Proclamation Observing June 19th as Juneteenth - Freedom Day Prepared By Seth Kaempfer, Equity and Inclusion Manager Summary For more than 150 years, Black Americans celebrate June 19th, or Juneteenth, as Freedom Day in recognition of the end of slavery. Although President Abraham Lincoln ratified the Emancipation Proclamation to abolish slavery on January 1st, 1863, slaveholders in Texas withheld information of abolition from enslaved Black Americans until Union troops shared the news on June 19th, 1865. As word spread Black Americans nationwide collectively celebrated their freedom and called the celebration Juneteenth, a combination of June and Nineteenth. Black communities across the nation still celebrate and recognize Juneteenth, also known as Freedom Day, as the end of slavery. The proclamation calls for the recognition of June 19th as "Juneteenth - Freedom Day" and the continued commitment to dismantle oppressive systems impacting the descendants of formerly enslaved Black Americans. During the two weeks of June 17th and 24th, the City of Golden Valley will support community celebrations of Kumbayah - The Juneteenth Story put on by Sweet Potato Comfort Pie. In accordance with the State of Minnesota and the signing of Juneteenth as a state holiday, City offices will be closed and no public business will be conducted this upcoming June 19th, 2024 as well as future dates. Legal Considerations This item did not require legal review. Equity Considerations This proclamation aligns with the City's commitment to diversity, equity, and inclusion and the City's welcome statement. The City supports and honors individuals of all backgrounds and believes it is critical to acknowledge celebrations and historical makers such as Juneteenth to both educate community and staff as well as create space for belonging of these richly diverse community.

Approve Contract for 2024 Fog Seal Project with Allied Blacktop Company Prepared By Tim Kieffer, Public Works Director Marshall Beugen, Street and Vehicle Maintenance Superintendent Summary The city previously used chip seal to preserve asphalt pavements. Chip seal is a process in which small granite rocks are spread over an asphalt emulsifier to seal the pavement and postpone future deterioration. This approach began to display premature signs of failure in the early 2000s. The top layer of pavement would delaminate causing potholes to form. The city discontinued chip sealing in 2012 until a solution could be found. Staff began pilot projects using newer technologies to determine the most cost-effect long-term solution to pavement preservation. One alternative is fog seal. Fog seal consists of a light application of diluted, slow setting emulsion that penetrates the pavement surface to slow oxidation and keep the pavement flexible. The city initially fog sealed in 2019 with good results, then again in 2022 and 2023. This year's project are roads in Maintenance District 3 that have not been chip sealed and the 2022 PMP. Financial or Budget Considerations Staff received one quote on June 11, 2024, from Allied Blacktop Company for $96,072.50. Funding for the fog sealing project will come from the Streets Capital Improvement Plan which has $250,000 dedicated for Pavement Surface Treatments (S-044). Legal Considerations The City Attorney has reviewed and approved the contract. Equity Considerations Staff solicited quotes from twelve contractors, including nine Disadvantaged Business Enterprises using the Minnesota Unified Certification Program database, and three community organizations that work with Minority and Women Business Enterprises. Recommended Action Motion to authorize the Mayor and Interim City Manager to execute the Contract for 2024 Fog Seal 16 Project with Allied Blacktop Company in the form approved by the City Attorney.

Approve Pipeline Encroachment Agreement With Union Pacific Railroad for Zane Avenue & Lindsay Street Improvements (Proj. No. 23-02) Prepared By Michael Ryan, City Engineer Summary This agreement between the City and Union Pacific Railroad (UPRR) is required for the construction of Zane Avenue and Lindsay Street Improvements, as part of the City’s Pavement Management Plan. This agreement specifically allows for the construction of storm sewer located within UPRR right-of-way. A license fee of $22,990 is a requirement of the agreement. Financial or Budget Considerations This agreement requires a $22,990 payment as a license fee, due and payable to UPRR upon execution of the agreement. This license fee has been factored in project cost estimates, which range between $8.9MM and $9.1MM, and is included in the Zane & Lindsay project budget as a line item. Legal Considerations Access and improvements within railroad right-of-way are subject to legal agreements, license fees, and coordination with railroad personnel. Railroad agreements, including this Pipeline Encroachment Agreement and similar previously authorized agreements, are common in the industry. This agreement would be effective until completion of associated improvements, and termination of the agreement. The City Attorney has reviewed and approved the Pipeline Encroachment Agreement. Equity Considerations The City’s work to execute our Pavement Management Program is consistent with the unbiased programs and services pillar of the City’s Equity Plan. The Pavement Management Program is unbiased, prioritizing streets that are not constructed to current standards, and streets that objectively have low Pavement Quality Index scores. This approach provides safe streets, reliable service, and consistent experiences for the community. Further, this Pipeline Encroachment Agreement allows specifically for storm sewer improvements that benefit the community beyond the local extents of the Zane Avenue & Lindsay Street Improvements project, by improving drainage capacity and reducing the potential for flooding in all areas that drain to, or away from, this project, including public spaces available to our entire community. 35 Recommended Action Motion to Approve Pipeline Encroachment Agreement With Union Pacific Railroad for Zane Avenue & Lindsay Street Improvements. Majority vote needed.

(402) 501-0340 Pipeline Crossing 06/05/18 Form Approved, AVP Law EXHIBIT B GENERAL TERMS AND CONDITIONS Section 1. LIMITATION AND SUBORDINATION OF RIGHTS GRANTED. A. The foregoing grant is subject and subordinate to the prior and continuing right and obligation of Licensor to use and maintain its entire property including the right and power of Licensor to construct, maintain, repair, renew, use, operate, change, modify or relocate railroad tracks, signal, communication, fiber optics, or other wirelines, pipelines and other facilities upon, along or across any or all parts of its property, all or any of which may be freely done at any time or times by Licensor without liability to Licensee or to any other party for compensation or damages. B. The foregoing grant is also subject to all outstanding superior rights (including those in favor of licensees and lessees of Railroad Property) and the right of Licensor to renew and extend the same, and is made without covenant of title or for quiet enjoyment. It shall be Licensee's sole obligation to obtain such additional permission, license and grants necessary on account of any such existing rights. Section 2. ENGINEERING REQUIREMENTS; PERMITS. A. Licensee's Facilities will be designed, constructed, operated, maintained, repaired, renewed, modified, reconstructed, removed, or abandoned in place on Railroad Property by Licensee or its contractor to Licensor's satisfaction and in strict conformity with: (i) Licensor’s current engineering standards and specifications, including those for shoring and cribbing to protect Licensor's railroad operations and facilities ("UP Specifications"), except for variances approved in advance in writing by Licensor’s Assistant Vice President Engineering – Design or its authorized representative ("UP Engineering Representative"); (ii) such other additional safety standards as Licensor, in its sole discretion, elects to require, including, without limitation, American Railway Engineering and Maintenance-of-Way Association ("AREMA") standards and guidelines (collectively, "UP Additional Requirements"); and (iii) all applicable laws, rules, and regulations, including any applicable Federal Railroad Administration and Federal Energy Regulatory Commission regulations and enactments (collectively, "Laws"). If there is any conflict between UP Specifications, UP Additional Requirements, and Laws, the most restrictive will apply. B. Licensee shall keep the soil over Licensee's Facilities thoroughly compacted, and maintain the grade over and around Licensee's Facilities even with the surface of the adjacent ground. C. If needed, Licensee shall secure, at Licensee's sole cost and expense, any and all necessary permits required to perform any work on Licensee's Facilities. Section 3. NOTICE OF COMMENCEMENT OF WORK; EMERGENCIES. A. Licensee and its contractors are strictly prohibited from commencing any work associated with Licensee's Facilities without Licensor's written approval that the work will be in strict compliance with the "ENGINEERING REQUIREMENTS; PERMITS" Section of this Exhibit B. Upon Licensor's approval, Licensee shall contact both of Licensor's field representatives ("Licensor's Field Representatives") at least ten (10) days before commencement of any work on Licensee's Facilities. B. Licensee shall not commence any work until: (1) Licensor has determined whether flagging or other special protective or safety measures ("Safety Measures") are required for performance of the work pursuant to the "FLAGGING" Section of this Exhibit B and provided Licensee written 43 Union Pacific Railroad Real Estate 1400 Douglas Street Stop 1690 Omaha, Nebraska 68179-1690 fx. (402) 501-0340 authorization to commence work; and (2) Licensee has complied with the "PROTECTION OF FIBER OPTIC CABLE SYSTEMS" Section of this Exhibit B. C. If, at any time, an emergency arises involving Licensee's Facilities, Licensee or its contractor shall immediately contact Licensor's Response Management Communications Center at (888) 877-7267. Section 4. FLAGGING. A. Following Licensee's notice to Licensor's Field Representatives required under the "NOTICE OF COMMENCEMENT OF WORK; EMERGENCIES" Section of this Exhibit B, Licensor shall inform Licensee if Safety Measures are required for performance of the work by Licensee or its contractor on Railroad Property. If Safety Measures are required, no work of any kind may be performed by Licensee or its contractor(s) until arrangements for the Safety Measures have been made and scheduled. If no Safety Measures are required, Licensor will give Licensee written authorization to commence work. B. If any Safety Measures are performed or provided by Licensor, including but not limited to flagging, Licensor shall bill Licensee for such expenses incurred by Licensor, unless Licensor and a federal, state, or local governmental entity have agreed that Licensor is to bill such expenses to the federal, state, or local governmental entity. Additional information regarding the submission of such expenses by Licensor and payment thereof by Licensee can be found in the "LICENSEE’S PAYMENT OF EXPENSES" Section of this Exhibit B. If Licensor performs any Safety Measures, Licensee agrees that Licensee is not relieved of any of responsibilities or liabilities set forth in this Agreement. C. For flagging, the rate of pay per hour for each flagger will be the prevailing hourly rate in effect for an eight-hour day for the class of flagmen used during regularly assigned hours and overtime in accordance with Labor Agreements and Schedules in effect at the time the work is performed. In addition to the cost of such labor, a composite charge for vacation, holiday, health and welfare, supplemental sickness, Railroad Retirement and unemployment compensation, supplemental pension, Employees Liability and Property Damage, and Administration will be included, computed on actual payroll. The composite charge will be the prevailing composite charge in effect at the time the work is performed. One and one-half times the current hourly rate is paid for overtime, Saturdays and Sundays, and two and one-half times current hourly rate for holidays. Wage rates are subject to change, at any time, by law or by agreement between Licensor and its employees, and may be retroactive as a result of negotiations or a ruling of an authorized governmental agency. Additional charges on labor are also subject to change. If the wage rate or additional charges are changed, Licensee (or the governmental entity, as applicable) shall pay on the basis of the new rates and charges. D. Reimbursement to Licensor will be required covering the full eight-hour day during which any flagger is furnished, unless the flagger can be assigned to other railroad work during a portion of such day, in which event reimbursement will not be required for the portion of the day during which the flagger is engaged in other railroad work. Reimbursement will also be required for any day not actually worked by the flaggers following the flaggers' assignment to work on the project for which Licensor is required to pay the flaggers and which could not reasonably be avoided by Licensor by assignment of such flaggers to other work, even though Licensee may not be working during such time. When it becomes necessary for Licensor to bulletin and assign an employee to a flagging position in compliance with union collective bargaining agreements, Licensee must provide Licensor a minimum of five (5) days notice prior to the cessation of the need for a flagger. If five (5) days notice of cessation is not given, Licensee will still be required to pay flagging charges for the days the flagger was scheduled, even though flagging is no longer required for that period. An additional ten (10) days notice must then be given to Licensor if flagging services are needed again after such five day cessation notice has been given to Licensor. 44 Union Pacific Railroad Real Estate 1400 Douglas Street Stop 1690 Omaha, Nebraska 68179-1690 fx. (402) 501-0340 Section 5. SAFETY. A. Safety of personnel, property, rail operations and the public is of paramount importance in the prosecution of any work on Railroad Property performed by Licensee or its contractor, and takes precedence over any work on Licensee's Facilities to be performed Licensee or its contractors. Licensee shall be responsible for initiating, maintaining and supervising all safety operations and programs in connection with any work on Licensee's Facilities. Licensee and its contractor shall, at a minimum comply, with Licensor's then current safety standards located at the below web address ("Licensor's Safety Standards") to ensure uniformity with the safety standards followed by Licensor's own forces. As a part of Licensee's safety responsibilities, Licensee shall notify Licensor if it determines that any of Licensor's Safety Standards are contrary to good safety practices. Licensee and its contractor shall furnish copies of Licensor's Safety Standards to each of its employees before they enter Railroad Property. Union Pacific Current Safety Requirements B. Licensee shall keep the job site on Railroad Property free from safety and health hazards and ensure that their employees are competent and adequately trained in all safety and health aspects of the work. C. Licensee represents and warrants that all parts of Licensee's Facilities within and outside of the limits of Railroad Property will not interfere whatsoever with the constant, continuous, and uninterrupted use of the tracks, property, and facilities of Licensor, and nothing shall be done or suffered to be done by Licensee at any time that would in any manner impair the safety thereof. D. Licensor's operations and work performed by Licensor’s personnel may cause delays in Licensee's or its contractor's work on Licensee's Facilities. Licensee accepts this risk and agrees that Licensor shall have no liability to Licensee or any other person or entity for any such delays. Licensee must coordinate any work on Railroad Property by Licensee or any third party with Licensor's Field Representatives in strict compliance with the "NOTICE OF COMMENCEMENT OF WORK; EMERGENCIES" Section of this Exhibit E. Licensor shall have the right, if it so elects, to provide any support it deems necessary for the safety of Licensor's operations and trackage during Licensee's or its contractor's construction, maintenance, repair, renewal, modification, relocation, reconstruction, or removal of Licensee's Facilities. In the event Licensor provides such support, Licensor shall invoice Licensee, and Licensee shall pay Licensor as set forth in the "LICENSEE'S PAYMENT OF EXPENSES" Section of this Exhibit B. F. Licensee may use unmanned aircraft systems ("UAS") to inspect Licensee's Facilities only upon the prior authorization from and under the direction of Licensor's Field Representatives. Licensee represents and warrants that its use of UAS on Railroad Property will comply with Licensor's then-current Unmanned Aerial Systems Policy and all applicable laws, rules and regulations, including any applicable Federal Aviation Administration regulations and enactments pertaining to UAS. Section 6. PROTECTION OF FIBER OPTIC CABLE SYSTEMS. Fiber optic cable systems may be buried on Railroad Property. Protection of the fiber optic cable systems is of extreme importance since any break could disrupt service to users resulting in business interruption and loss of revenue and profits. In addition to the notifications required under the "NOTICE OF COMMENCEMENT OF WORK; EMERGENCIES" Section of this Exhibit B, Licensee shall complete the required form at up.com/CBUD to determine if fiber optic cable is buried anywhere on Railroad Property to be used by Licensee. If it is, Licensee shall telephone the telecommunications company(ies) involved, and arrange for a cable locator, make arrangements for relocation or other protection of the fiber optic cable, all at Licensee’s expense, and will not commence any work on Railroad Property until all such protection or relocation has been completed. 45 Union Pacific Railroad Real Estate 1400 Douglas Street Stop 1690 Omaha, Nebraska 68179-1690 fx.

Licensee shall fully pay for all materials joined, affixed to and labor performed on Railroad Property in connection with the construction, maintenance, modification, reconstruction, repair, renewal, revision, relocation, or removal of Licensee's Facilities, and shall not permit or suffer any mechanic’s or materialman’s lien of any kind or nature to be enforced against the property for any work done or materials furnished thereon at the instance or request or on behalf of Licensee. Licensee shall promptly pay or discharge all taxes, charges, and assessments levied upon, in respect to, or on account of Licensee's Facilities, to prevent the same from becoming a charge or lien upon any property of Licensor, and so that the taxes, charges, and assessments levied upon or in respect to such property shall not be increased because of the location, construction, or maintenance of Licensee's Facilities or any improvement, appliance, or fixture connected therewith placed upon such property, or on account of Licensee’s interest therein. Where such tax, charge, or assessment may not be separately made or assessed to Licensee but shall be included in the assessment of the property of Licensor, then Licensee shall pay to Licensor an equitable proportion of such taxes determined by the value of Licensee’s property upon property of Licensor as compared with the entire value of such property. C. As set forth in the "FLAGGING" Section of this Exhibit B, Licensor shall have the right, if it so elects, to provide any Safety Measures Licensor deems necessary for the safety of Licensor's operations and trackage during Licensee's or its contractor's construction, maintenance, modification, reconstruction, repair, renewal, revision, relocation, or removal of Licensee's Facilities, including, but not limited to supervision, inspection, and flagging services.

Licensee shall pay to Licensor the total amount listed on such invoice within thirty (30) days of Licensee's receipt of such invoice. Section 8. MODIFICATIONS TO LICENSEE'S FACILITIES. A. This grant is subject to Licensor's safe and efficient operation of its railroad, and continued use and improvement of Railroad Property (collectively, "Railroad's Use"). Accordingly, Licensee shall, at its sole cost and expense, modify, reconstruct, repair, renew, revise, relocate, or remove (individually, "Modification", or collectively, "Modifications") all or any portion of Licensee's Facilities as Licensor may designate or identify, in its sole discretion, in the furtherance of Railroad's Use. B. Upon any Modification of all or any portion of Licensee's Facilities to another location on Railroad Property, Licensor and Licensee shall execute a Supplemental Agreement to this Pipeline Agreement to document the Modification(s) to Licensee's Facilities on Railroad Property. If the Modifications result in Licensee's Facilities moving off of Railroad Property, this Agreement will terminate upon Licensee's completion of such Modification(s) and all requirements contained within the "TERMINATION; REMOVAL OF LICENSEE’S FACILITIES" Section of this Exhibit B. Any such Modification(s) off of Railroad Property will not release Licensee from any liability or other obligation of Licensee arising prior to and upon completion of any such Modifications to the Licensee's Facilities. Section 9. RESTORATION OF RAILROAD PROPERTY. In the event Licensee, in any manner moves or disturbs any property of Licensor in connection with the construction, maintenance, modification, reconstruction, repair, renewal, revision, relocation, or removal of Licensee's Facilities, then, Licensee shall, as soon as possible and at Licensee’s sole cost 46 Union Pacific Railroad Real Estate 1400 Douglas Street Stop 1690 Omaha, Nebraska 68179-1690 fx.

Adopt Resolution No. 24-042 Approving Membership in the Hennepin County Fire Chiefs Association Prepared By Bethany Brunsell, Assistant Fire Chief Summary Hennepin County Fire Chiefs Association (HCFCA) was established in 1961 and the Golden Valley Fire Department has been a long-standing member of the HCFCA. The HCFCA is an organization of fire departments in Hennepin County as well as groups and agencies that support the fire service, whose purpose is to discuss and promote fire safety, exchange ideas and search for solutions, conduct research, facilitate educational programs, and promote the spirit of cooperation between fire departments and other emergency response organizations within Hennepin County, Minnesota. At the direction of HCFCA's membership and Board of Directors, HCFCA has organized as a nonprofit corporation and enable application for federal tax-exempt status. On January 8, 2024, the Hennepin County Fire Chiefs Association, Inc. was registered as a nonprofit corporation with the Office of the Minnesota Secretary of State. As part of membership to the HCFCA, each member fire department's governing body is being asked to adopt a resolution approving membership in the Hennepin County Fire Chiefs Association. Financial or Budget Considerations No impact. Hennepin County Fire Chiefs Association membership dues for Chief-level officers have been part of the Golden Valley Fire Department's annual budget for many years. Legal Considerations The Hennepin County Fire Chiefs Association becoming a nonprofit corporation increases legal requirements and oversight for the Association compared to the previous status of operating without such legal requirements. This resolution allows for Golden Valley Fire Department's membership to the HCFCA but does not require participation if the City chooses to end its membership. The City Attorney has not reviewed the Resolution Approving Membership in the Hennepin County Fire Chiefs Association; however the Resolution was created using an approved template without changes to the template. 52 Equity Considerations This resolution has no impact on equity considerations. In 2023, as a member of the Hennepin County Fire Chiefs Association Board of Directors, Golden Valley Fire Department Fire Chief Brunsell worked with other Board members to add an equity statement to the Association's Bylaws. Recommended Action Motion to adopt Resolution No. 24-042 approving membership in the Hennepin County Fire Chiefs Association.

The impact on families and individuals can be immense and damages to businesses can result in regional economic consequences. The time, money, and effort to respond to and recover from these disasters divert public resources and attention from other important programs and problems. Hennepin County is vulnerable to a variety of potential hazards. With seven Presidential Disaster Declarations since 2010, Hennepin County recognizes the consequences of disasters and the need to reduce the impacts of natural and manmade hazards. This HMP focuses primarily on natural hazard. The elected and appointed officials of the County also know that with careful selection, mitigation actions in the form of projects and programs can become long‐term, cost‐effective means for reducing the impact of natural and manmade hazards. The 2024 Hennepin County Multi‐Jurisdictional Hazard Mitigation Plan (HMP or the Plan) for Hennepin County, Minnesota, was prepared with input from the Mitigation Planning Regional Review Committee, the Hennepin County Emergency Management (HCEM) Planning cell, county residents, responsible officials, other HCEM department members, the state hazard mitigation officer, and in accordance with Federal Emergency Management Agency (FEMA). The process to develop the HMP included a year of coordination and collaboration with representatives from all the jurisdictions in Hennepin County. The HMP will guide the County toward paying down risk, greater disaster resistance in harmony with the character, and needs of the community. This section of the HMP includes an overview of the Plan, a discussion of the Plan’s purpose and authority, and a description of the 45 incorporated cities, the Minneapolis/St. Paul Airport, and the Fort Snelling unincorporated portion of the County. 1.1.1. PLAN DESCRIPTION AND REQUIREMENTS Federal legislation has historically provided funding for disaster relief, recovery, and some hazard mitigation planning. The Disaster Mitigation Act of 2000 (DMA 2000) is the latest legislation to improve this planning process (Public Law 106‐390). The new legislation reinforces the importance of mitigation planning and emphasizes planning for disasters before they occur. As such, DMA 2000 establishes a pre‐ disaster hazard mitigation program and requirements for the national post‐disaster Hazard Mitigation Grant Program (HMGP). Section 322 of DMA 2000 specifically addresses mitigation planning at the state and local levels. It identifies requirements that allow HMGP funds to be used for planning activities and increases the amount of HMGP funds available to states that have developed a comprehensive, enhanced mitigation plan prior to a disaster. States and communities must have an approved mitigation plan in place prior to receiving post‐disaster HMGP funds. Local and tribal mitigation plans must demonstrate that their proposed mitigation measures are based on a sound planning process that accounts for the risk to and the capabilities of the individual communities. State governments have certain responsibilities for 67 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 10 implementing Section 322, including: Preparing and submitting a standard or enhanced state mitigation plan. Reviewing and updating the state mitigation plan every three years. Providing technical assistance and training to local governments to assist them in applying for HMGP grants and in developing local mitigation plans; and Reviewing and approving local plans if the state is designated a managing state and has an approved enhanced plan. DMA 2000 is intended to facilitate cooperation between state and local authorities, prompting them to work together. It encourages and rewards local and state pre‐disaster planning and promotes sustainability as a strategy for disaster resistance. This enhanced planning network is intended to enable local and state governments to articulate accurate needs for mitigation, resulting in faster allocation of funding and more effective risk reduction projects. FEMA prepared an Interim Final Rule (IFR), published in the Federal Register on February 26, 2002 (44 CFR Parts 201 and 206), which establishes planning and funding criteria for states and local communities. The Plan has been prepared to meet Homeland Security Emergency Management (HSEM) and FEMA requirements thus making the County eligible for funding and technical assistance from state and federal hazard mitigation programs. FEMA also requires that this plan meet the Local Mitigation Planning Policy Guide FP 206‐21‐0002, released April 19, 2022, and went into effect on April 19, 2023. This policy provides 8 planning elements that address 51 standards/requirements that must be addressed for FEMA Hazard Mitigation Plan approval. 68 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 11 2.1. AUTHORITY C1 This updated HMP complies with all requirements set forth by HSEM and the Robert T. Stafford Disaster Relief and Emergency Assistance Act, Section 104 of the Disaster Mitigation of 2000. In addition, it complies with all of FEMA’s Final Rule 44 CFR 201.6 (c)(3), which outlines criteria for approval of mitigation plans. 2.2. SCOPE The HMP identifies 19 natural hazards that pose a threat to this county, including both incorporated and unincorporated areas, and provides goals, objectives, and a plan of action for mitigating these hazards. This plan addresses and addresses natural hazards affecting Hennepin County as determined by frequency of event, economic impact, deaths, and injuries. The plan addresses hazard risk, reviews current state and local hazard mitigation capabilities, develops mitigation strategies and identifies partner agency and other interagency working group’s actions to address mitigation needs. The plan, as agreed upon by all participating jurisdictions, assists in collaborating local mitigation plans or projects. Mitigation recommendations are provided through various federal, state, and local agency discussion and research. The HMP identifies a variety of existing literature and resources that will be used to assist participants in this plan, to succeed in their mitigation project application efforts. This is accomplished by establishing countywide mitigation strategies, providing technical resources through state, county and local agency staff expertise and support, to include, providing financial assistance through various grant programs, declarations, training and education and other jurisdiction initiatives for example partnering within community capital improvement. 2.3. PURPOSE FEMA defines Hazard Mitigation as any sustained action taken to reduce or eliminate long‐term risk to people and property from natural hazards for example, but not all‐inclusive, flooding, storms, high winds, wildfires, earthquakes, etc. Mitigation efforts undertaken by communities will help reduce or eliminate damages to buildings and infrastructure, such as water supplies, sewers, and utility transmission lines, as well as natural, cultural, and historic resources. The objective of the HMP is to rationalize the process of determining appropriate mitigation actions in protecting citizens, critical facilities, infrastructure, private property, and the surrounding environment from natural hazards. This objective can be achieved by identifying potential hazards in the jurisdiction, share information, discuss options, determine funding availability, and submit applications for qualified projects that would mitigate the effects of those hazards identified. This plan provides a framework for planning against all natural hazards in the county. The HMP can be used as a foundation beyond local mitigation plans in identifying additional collaborative partnerships in the county who wish to participate in paying down risk within their communities. 2.4. ADOPTION F1a, F2a In 2010, the incorporated cities and Hennepin County formed an agreement which established the unification in the development of writing this plan. The Hennepin County Board of Commissioners and City Councils from each participating municipality were required to adopt the plan prior to its submittal to HSEM and FEMA for final adoption. SECTION 2 PLAN PURPOSE, AUTHORITY AND ADOPTION 69 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 12 The Plan is intended to serve many purposes, including: Enhance Public Awareness and Understanding – to help residents of the County better understand the natural and manmade hazards that threaten public health, safety, and welfare; economic vitality; and the operational capability of important institutions. Create a Decision Tool for Leadership, supervisors, or management – to provide information that key decision makers of local government, business and industry, community associations, and other key institutions and organizations that need to take steps or actions by addressing vulnerabilities in reducing loss of life, prevent injury, and critical infrastructure damage with unforeseen future disasters. Promote compliance with State and Federal Program Requirements‐ to ensure that Hennepin County and its incorporated cities can take full advantage of state and federal grant programs, policies, and regulations that encourage or mandate that local governments develop comprehensive hazard mitigation plans. Enhance Local Policies for Hazard Mitigation Capability‐ to provide the policy basis for mitigation actions that should be promulgated by participating jurisdictions to create a more disaster resistant future. Provide Inter‐Jurisdictional Coordination of Mitigation‐Related Programming‐ to ensure that proposals for mitigation initiatives are reviewed and coordinated among participating jurisdictions within the county; and Achieve Regulatory Compliance ‐ To qualify for certain forms of federal aid for pre and post disaster funding, local jurisdictions must comply with the federal DMA 2000 and its implementing regulations (44CFR Section 201.6). DMA 2000 intends for hazard mitigation plans to remain relevant and current. Therefore, it requires that state hazard mitigation plans are updated every three years and local plans, including Hennepin County’s every five years. This means that the HMP for Hennepin County uses a “five‐year planning horizon”. It is designed to carry the County through a five‐year term, after which its goals, objectives, and actions will be reviewed with revisions being submitted to the County Board for adoption and approval. 70 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 13 This section provides an overview of the planning process used to update the 2023 Hennepin County HMP. It includes who was involved in preparing the plan, how the public and stakeholders were involved, and the review and incorporation of existing plans and studies. 3.1. Why Prepare This Plan – The Big Picture Hazard mitigation can be defined as, “to reduce or alleviate the loss of life, personal injury, and property damage that can result from a disaster through both long and short‐term strategies”. It involves strategies such as planning, policy changes, programs, projects, and other activities that can mitigate the impacts of hazards. The responsibility for hazard mitigation lies with many, including private property owners; business and industry; and local, state, and federal government. Types of hazard mitigation measures include the following (not all‐inclusive): • Structural hazard control or protection projects • Retrofitting of facilities • Acquisition and relocation of structures • Development of mitigation standards, regulations, policies, and programs • Public awareness and education programs • Development or improvement of warning systems The benefits of hazard mitigation include the following (not all‐inclusive): • Saving lives, protecting the health of the public, and reducing injuries • Preventing or reducing property damage • Reducing economic losses • Minimizing social dislocation and stress • Reducing agricultural losses • Maintaining critical facilities in functioning order • Protecting infrastructure from damage • Protecting mental health • Reducing legal liability of government and public officials The Disaster Mitigation Act (DMA) of 2000 (Public Law 106‐390) required state and local governments to develop hazard mitigation plans as a condition for federal disaster grant assistance. Prior to 2000, Federal disaster funding focused on disaster relief and recovery with limited funding for hazard mitigation planning. The DMA increased the emphasis on planning for disasters before they occur. The DMA encourages state and local authorities to work together on pre‐disaster planning, and it promote sustainability for disaster resistance. “Sustainable hazard mitigation” includes the sound management of natural resources and the recognition that hazards, and mitigation must be understood in the largest possible social and economic context. The enhanced planning network called for by the DMA helps local government’s articulate accurate needs for mitigation, resulting in faster allocation of funding and more cost‐effective risk reduction projects. SECTION 3 PLANNING PROCESS A 71 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 14 3.2.1. Hennepin County’s Response to the DMA In 2005, Hennepin County Emergency Management (HCEM) and municipalities agreed to work together to establish a framework for hazard mitigation planning that would meet the local mitigation planning requirements of Title 44 of the Code of Federal Regulations (CFR 44). The result was a HMP that included Hennepin County Departments, municipalities, and special jurisdictions. The plan provided local governments with the tools to complete individual mitigation objectives and actions, as well as completing a vulnerability assessment to meet their needs, while pooling resources and eliminating redundant planning activities. 3.2.2. Purpose for Planning HCEM and its planning partners have a long‐standing history of collaboration, proactive planning, and program implementation by developing and adopting a multi‐jurisdiction all hazard mitigation plan. Strategies in this plan were selected because they meet element requirements, provide eligibility for project funding, and because they meet the needs of the planning partners for their residents. This HMP will identify strategies, goals, objectives, projects, costs, and safety information, to reduce risk from natural hazards. This HMP will help guide and coordinate mitigation activities throughout Hennepin County. The plan has been developed to meet the following objectives: Meet or exceed requirements of the DMA. Enable all HMP participating partners to apply for federal grant funding to reduce risk through mitigation. Meet the needs of each planning partner as well as state and federal requirements. Create a risk assessment that focuses on Hennepin County’s nineteen (19) identified hazards. Create a single planning document that integrates all planning partners into a framework that supports partnerships within the County and puts all partners on the same planning cycle for future updates. Create opportunity for local governments in the County not included in the previous plan to gain DMA compliance. Meet the planning requirements of FEMA’s Community Rating System (CRS), allowing planning partners that participate in the CRS program to maintain or enhance their CRS classifications. Coordinate existing plans and programs so that high‐priority initiatives and projects to mitigate possible disaster impacts have an opportunity to funded and implemented. 3.2.3. Who Will Benefit from this Plan? All communities, businesses, and residents of Hennepin County are the ultimate beneficiaries of this HMP. The plan reduces risk for those who live in, work in, and visit Hennepin County. It provides a viable planning framework for all natural hazards that may impact the County. Participation in development of the plan by key stakeholders in the County help reduce risk and ensure that outcomes will be mutually beneficial. The resources and background information in the plan are applicable countywide, and the plan’s goals and recommendations can lay the groundwork for the development and implementation of local mitigation projects, open discussions or share information across multiple jurisdictions wanting to participate in the same mitigation project and develop or build relationships. 72 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 15 3.2.4. Plan Update – The Planning Process A1A A1B Hennepin County Emergency Management assumes the position of lead agency in preparing the HMP for the county and participating jurisdictions. The HMP revision process took one year and six months to complete, beginning in August 2022 with plan adoption in February 2024. Forty‐two municipalities, three cities that share boundaries with adjacent counties, Fort Snelling, and MSP Airport were considered in this plan. County Departments are also covered under the 2023 Hennepin County HMP. The planning process used to develop this Plan is as follows: A. A Regional Review Working Group (RRWG) was created to assess the plan. The RRWG consisted of one Hennepin County Emergency Management staff member and the regional chair of each of the four planning groups. The RRWG reviewed this plan mitigation goals and objectives, determined that using the existing 2018 plan was reasonable to follow the framework for revision, reviewed various county plans, and used the Local Mitigation Planning Policy Guide, FP 206‐21‐ 0002, Released April 19, 2022, Effective April 19, 2023, OMB Collection #1660‐0062. B. The RRWG met five times throughout 2022‐2023. (See TABLE 3.16A for schedule) C. The plan established and carried over many of the FEMA elements from 2018 but placed an emphasis primarily on those FEMA elements that were added in 2022 to include, critical infrastructure, underserved populations, and climate change. D. Hennepin County continued with the Hazard Mitigation Plan “Combination Model” for their planning and review process. Using this model, Hennepin County’s four Area Planning Groups: Minneapolis Group (5), Lake Minnetonka Regional Planning Group (21), North Suburban Regional Planning Group (14) and South Planning Group (7) appointed one representative to serve on the Hennepin County Mitigation Planning and Review Team to act on behalf of their regional group. This model assisted several smaller municipalities that had limited resources to participate in the overall early planning stages but were able to meet regionally or specifically with HCEM to work through their supporting documentation for local plan adoption. (See section 3.13) E. Public Participation was established using a community survey using a similar template from 2018 but made changes to meet the FEMA elemental requirements as recommended in 2022. The survey was created by HCEM and disseminated through the county social media sites and several city websites. See Section 7: appendix C) TABLE 3.5A below is a summary of the 2024 HMP Update Process: Task Date Action Task 1: Notification and FEMA guidelines review August 2022 State notification was received in preparation to resubmit the next 5‐year plan. A review of the 2018 Hennepin County HMP was conducted by HCEM. It was determined that the plan needed some revision so that it was consistent with the new 2022 FEMA Local Mitigation Planning Policy Guide. All meetings were documented and included in this revision (see TABLE 3.16A) Task 2: Building working groups and planning teams August 2022‐ June 2023 A Regional Review Working Group and Mitigation Planning Teams were formed to reflect county, local jurisdiction, and partner organization interests. Only 73 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 16 Task Date Action one member of the former 2018 steering committee was involved in this update. Each participating jurisdiction had at least one representative as a member of a planning team Task 3: Create an Outreach Strategy May 2023‐ November 2023 The county engaged the public and its participating jurisdictions through surveys, regional, and quarterly meetings. Stakeholder meetings were also conducted by meeting independently with all 42 cities. Public and stakeholder involvement is described below. Task 4: Review Community Capabilities May 2023‐ January 2024 Capabilities were assessed by each jurisdiction’s emergency manager with additional support from HCEM, from open‐source information, local agency updates and resource list compiling Task 5: Risk Assessment 2010‐2024 The current overall hazard risk assessment was reviewed. All 7 federal declarations with natural hazard implication in Hennepin County since 2010, were considered. Each participant also reviewed risk against their priority 1‐ critical infrastructure. Hennepin County’s Regional Emergency Management Reference Collection was also available as a reference to assess risk. Task 6: Mitigation Strategies May 2023‐ November 2023 Ten goals were used to make decisions for paying down risk. Participants built strategies by assessing gaps and vulnerabilities within their jurisdictional boundaries against those goals. Each participating jurisdiction reviewed past projects that were completed or yet to be completed and were carried over to this HMP. Participants also submitted new mitigation projects for future projects. Task 7: Plan Maintenance Procedure 2024‐2029 Covid‐19 limited a normal review cycle during this revision period. The 2018 base plan, nineteen natural hazards, and all community qualifying documentation products were reviewed, updated, crossed over, or deleted for this 2024 plan. A cyclic review schedule will occur routinely with a local mitigation strategies (LMS) group. Task 8: Review and Adopt the Plan January 2024 A draft of the plan was reviewed by HCEM, participating jurisdictions of the plan, Hennepin County Board of Commissioners, the HSEM state hazard mitigation officer, and the Regional Review Working Group. The adopted plan (with some redaction) will be made available to the public via the county website and for participating agencies who wish to upload a redacted version to their city websites. The plan will be sent to HSEM/FEMA for approval February 2024. Each participating jurisdiction will also adopt this plan through resolution in QTR 1 2024 74 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 17 Task Date Action Task 9: Final Plan Delivery February 2024 Hennepin County Emergency Management will upload a redacted and unredacted version for State, County, local jurisdictions, and partner organization receipt. 3.2.5.

The appendices also received updates to the regulatory crosswalk and jurisdiction participation sheet. 75 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 18 3.2.6. Why Update 44 CFR stipulates that hazard mitigation plans must present a schedule for monitoring, evaluating, and updating project status of the plan. Updates provide an opportunity to reevaluate goals and objectives and assess if impacts of those determined actions are currently being or have been accomplished. If the intent is not being met the mitigation strategy may need to be reviewed or modified. Should this plan reach its expiration date, participants will not be able to pursue elements of federal funding under the Robert T. Stafford Act for which this adopted hazard mitigation plan is a prerequisite. 3.2.7. The Updated Plan – What is Different E2a There are only a few changes to this 2024 plan which includes a change in the overall number of participating agencies involved in the plan update process. So, while this plan is an update for several participants, it is also the initial plan for new emergency managers who have been hired, selected, or appointed since 2018. Therefore, it was important to establish a planning process that was consistent for returning or new participants. The updated plan differs from the 2018 plan as described below: The current risk assessment (VOL 1) continues to reflect the nineteen natural hazards identified in this HMP. The updates cover the period between 2018‐2023 and will providing new information regarding significant events within this new 5‐year timeline. The update (VOL 3) creates an opportunity for the County and participants to review the plan in whole and engage citizens directly through community outreach involvement, social media, and surveys in a coordinated approach to gage their perception of risk and support of the concept of risk reduction through mitigation. The plan (VOL 3) identifies new mitigation strategies, goals, ideas, or recommendations for all participants to review and consider. The critical infrastructure risk assessment (VOL 3) was prepared to be informative to local emergency managers and what facilities were critical in continuity and their daily operations. Identifying infrastructure with risk assessment should better support future grant applications by providing risk and vulnerability information that will directly support the measurement of “cost‐ effectiveness” required under FEMA mitigation grant programs. An additional capability accountability tool (VOL 1) was created to identify ordinance and regulation. The dashboards (VOL 3) were modified to reflect references, social media, city websites, and any updates as described by the jurisdiction’s emergency manager. Given the extent of changes in this update, readers should consider this to be a simple revised or modified plan. Previous or prior plan versions are used as references in identifying where relevant change and correlations are required through discussion and cyclic review. Federal or state data or information becomes relevant where new content is required to add to the next iteration in hazard mitigation planning. 3.3. Summary of Previous Planning Efforts HCEM developed its first HMP in 2005, which was led by then named Hennepin County Emergency Preparedness. A Local Mitigation Planning Team was created and served as the planning team. The plan included three generalized goals: 76 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 19 Protect life and Property. Execute activities that assist in protecting lives by making homes, businesses, infrastructure, critical facilities, and other property more resistant to losses from hazards. Improve hazard assessment information to make recommendations for new and for existing developments in areas vulnerable to hazards. Public Awareness Increase public awareness of the risks associated with hazards in the county. Provide information on tools, partnerships, opportunities, and funding resources to assist in implementing mitigation activities. Partnerships and Implementation Strengthen communication and coordinate participation among and within public agencies, citizens, nonprofit organizations, business, and industry to gain a vested interest in implementation. Encourage leadership within public and private sector organizations to prioritize and implement local, county, and regional hazard mitigation activities. In 2010, HCEM re‐wrote the plan for the update due to several changes in the County’s risk assessment as well as new technology (HAZUS‐MH) to estimate losses to critical infrastructure. A Steering Committee was made up of HCEM personnel as well as the City of Minneapolis’s then Emergency Preparedness Department. In 2015, the HMP expired. Between 2015‐2018, HCEM took an additional 26 months to do a complete review and overhaul to meet the FEMA elemental requirements. The steering committee provided seven goals and each participating community was deeply involved in the planning process. The final adoption of the plan took place in 2018. The 2018 HMP expired in August 2023. 3.10 Organization of the Plan The 2024 update to the HMP has undergone small changes from the 2018 version. Updates were made using FEMA policy guidance, mitigation planning teams, federal hazard mitigation strategies, and Hennepin County Emergency Management Director directive. The plan was organized to reflect current practice and recommended guidance. However, content from the previous versions will continue to be included. The HMP consists of and maintains three components, each are broken down in the following volumes: Volume 1: Background and County Profile (103 pages) Section 1: Introduction Section 2: Plan Purpose, Authority and Adoption Section 3: Planning Process Section 4: County Profile Section 5: Community Capability Assessment 77 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 20 Section 6: Hazard Mitigation Plan Maintenance Section 7: Appendices Volume 2: Hazard Inventory (359 pages) Section 1: Hazard Categories and Inclusions Section 2: Disaster Declaration History and Recent Trends Section 3: Climate Adaptation Considerations Section 4: Comprehensive Natural Hazard Assessment Profiles Section 5: Vulnerability Assessment Section 6: Cultural Resource Inventory Section 7: Critical Infrastructure Key Resources (CIKR) Volume 3: Community and Mitigation Strategies (291 Pages) Section 1: Mitigation Strategy, Goals and Objectives Section 2: Mitigation Action Plan Section 3: Mitigation Actions and Projects Section 4: Minnesota Mitigation Crosswalk Section 5: Acronyms and Abbreviations Section 6: Glossary Section 7: Appendices 3.11 Planning Objectives To develop the Hennepin County HMP update, the County followed a process that had the following primary objectives: Establish a Regional Review Working Group. Form a mitigation planning teams by jurisdiction. Coordinate planning sessions with each participating jurisdiction (42). Reviewing existing goals, objectives, actions, and past projects. Develop a hazard risk assessment addressing critical infrastructure and the nineteen natural hazards. Engage the Public through social media with an opportunity to participate in a survey. Add ordinance and regulations capability assessment. 3.12 Establish a Regional Review Working Group Hazard mitigation planning invites collaboration and support among participating jurisdictions whose communities can be affected by hazard losses. Participating jurisdictions can create partnerships that pool resources to achieve a common vision for the community. A Regional Review Working Group was formed to provide review, observations, and recommendations for plan updates. The members of this committee included the four chairs of the regional planning groups and a staff member from Hennepin County Emergency Management. Several meetings took place in 2022‐ 2023. Regional Review Working Group meeting minutes are provided in Section 7: Appendix A (page 59‐62) 78 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 21 3.13 Forming a Mitigation Planning Team A2a To assist with the development and implantation of this HMP update, the Regional Review Working Group agreed that the Mitigation Planning Team (MPT) would consist of at least one lead representative from each jurisdiction. HCEM’s Plans & Systems Integration Coordinator assumed the role as lead administrator for review and training, scheduling a 2‐hour block of instruction for each jurisdiction. Each jurisdiction could have as many representatives attend their mitigation document development training session. Additional meetings were available should a jurisdiction need additional support. A PowerPoint tutorial was created, and a SharePoint password was created to give and allow jurisdictions additional support to review guidance and document updates, if needed. The MPT leads are listed for each jurisdiction and their primary affiliation: Lakes Region Corcoran Matt Gottschalk Police Deephaven Cory Johnson Police Excelsior Brian Tholen Police Greenfield Margaret Webb City Admin Greenwood Brian Tholen Police Independence Gary Kroells Police Long Lake Marc Schultz Police Loretto Jason Nelson Police Maple Plain Gary Kroells Police Medina Jason Nelson Police Minnetonka Beach Corey Farniok Police Minnetrista Paul Falls Police Mound Greg Pederson Fire Orono Corey Farniok Police Rockford and Hanover Wright County St. Bonifacious Paul Falls Police Shorewood Brian Tholen Police Spring Park Corey Farniok Police Tonka Bay Brian Tholen Police Wayzata Marc Schultz Police Woodland Cory Johnson Police North Region Brooklyn Center Todd Berg Fire Brooklyn Park Shawn Conway Fire Champlain Glen Schneider Police Crystal Mark Ray Public Works Dayton Paul Enga Police Golden Valley Fire Maple Grove Tim Bush Fire Medicine lake Joshua Hauble Emergency Management New Hope Sarah Larson Fire Osseo Shane Mikkelson Police Plymouth Erik Fadden Police Robbinsdale Patrick Foley Police 79 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 22 Rogers Patrick Farrens Fire St. Anthony Zach Lundberg Public Works South Region Bloomington Ulyssess Seal Fire Chanhassen Carver County Eden Prairie Scott Gerber Fire Edina Andrew Slama Fire Hopkins Dale Specken Fire Minnetonka Aaron Morris Fire Richfield Jay Henthorne Fire St. Louis Park Steve Koering Fire East Region Minneapolis Eric Gustafson Emergency Manager 3.14 Coordinate with other Agencies A2a 44CFR requires that opportunities for involvement in the planning process be provided to neighboring communities, local and regional agencies involved in hazard mitigation, agencies with authority to regulate development, business, academia, agencies that represent socially vulnerable communities, and other private and non‐profit interests. The Mitigation Planning Team Representatives invited additional agencies that fall under those classifications from within their jurisdictions, as well as watershed and school districts. This effort resulted in the steering committee described below: All 43 municipalities in Hennepin County (EM’s, PW, School districts, Watersheds) Hennepin County Departments (GIS and Public Health) Xcel Energy University of Minnesota 3.15 Review of Existing Programs 44 CFR states that hazard mitigation planning must include review and incorporation, if appropriate, of existing plans, studies, reports, and technical information. In addition, the following programs can affect mitigation within the planning area: Hennepin County Emergency Operations Plan Emergency Operations Plans (Regional North, Regional Lakes, Independent South, and the City of Minneapolis) 2019 Minnesota State Hazard Mitigation Plan 2019 Anoka County Mitigation Plan 2019 Carver County Mitigation Plan 2022 Dakota County Mitigation Plan 2019 Ramsey County Mitigation Plan 2021 Scott County Mitigation Plan 2023 Washington County Mitigation Plan 2023 Wright‐County Mitigation Plan 80 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 23 One of the Review Committee’s actions was to review the 2019 Minnesota State Hazard Mitigation Plan (SHMP). The Review Committee identified hazards listed in the state plan (pg. 56) to which the Hennepin County planning area is susceptible and to determine if there was a need to expand the scope of the current Natural Hazard Risk Assessment. The SHMP includes 15/22 natural hazards which are currently identified in this HMP, the other seven being industrial or manmade hazards, which are not included in this plan. The Committee also reviewed the 2022 FEMA Local Mitigation Planning Policy Guide determining that three additional goals were required to meet the new guidance. 3.16 Plan Development Chronology/Milestones A1a TABLE 3.16A summarizes important milestones in the development of the plan update. 81 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 24 Plan Development Calendar of Events Date Event Milestone Attendance 2022 10/10/2022 10/26/2022 10/27/2022 HCEM Mtgs for community outreach Survey Questionnaire discussion, timeline, and buildout 2‐5 11/10/2022 Regional Review Working Group Mtg 1 Info sharing, establishing HMP timeline 7 11/16/2022 FEMA webinar Steven Green Hazard Mitigation planning guidance 5 12/01/2022 Community Outreach Survey Survey questionnaire launched 43 12/05/2022 Community Outreach Survey HMP email: QRC created and disseminated to provide survey link 42 12/07/2022 Community Outreach Survey HMP email: Provide update and additional survey information 42 2023 1/18/2023 Community Outreach Survey City Websites advertise survey opportunity and announce HMP revision UNK 1/30/2023 HCEM Staff Mtg Check on progress discussion, accept recommendations 2 2/22/2023 Community Outreach HEMC Quarterly mtg HMP progress, documents, and timeline update 82 4/20/2023 Regional Review Working Group Mtg 2 Plan completion timeline, 44 CFR element review, Natural Hazard review 5 5/18/2023 Regional Review Working Group Mtg 3 Progress updates, community planning visits, product checklist, timeline update 5 5/18/2023 Community Outreach HEMC Quarterly mtg HMP progress report 65 5/25/23 Community Outreach Lakes Group HMP information update 15 5/26/2023‐ 12/15/2023 Participating jurisdiction planning 1 on 1 city visits commence to plan HM.

State, Federal, and local information sources were used to identify any new data that has occurred over the past five‐year period. In addition, HCEM continues to use the Hennepin County Regional Emergency Management Reference Library and web‐based historical open‐source collection as a primary means in data gathering. 3.18 HCEM Regional Emergency Management Planning Reference Collection A4 The purpose of Hennepin County Emergency Managements Regional Emergency Management Planning Reference Collection (REMPRC) is intended to assist emergency managers and others involved in emergency mitigation, preparation, response, and recovery. The collection is oriented toward historical disasters, after actions, theory, emergency management strategic, operational, and tactical planning; training and exercise design; as well as education, professional development and the evolution of emergency management systems and processes. The reference material collected in the REMPRC was created in 2010 and is categorized into very specific subject matter areas as it relates to disaster. The priority is given to references related to the doctrine, organization, and professional practice of emergency management, including theory, assessments, strategies, plans, and after‐action reviews. Also collected are analysis and accounts of hazards or threats of a level that could require emergency management employment (natural, technological, and adversarial). The second priority is to gather references that are useful for understanding the present and future environment that may have applications for strategic assessment and planning (demographics, economic forecasts, technology assessments, etc.). Last, the REMPRC gathers materials related to emergency practices within the disciplines that make up the emergency management community (police, fire, emergency medical services, public works, public 83 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 26 health, etc.). Works dealing with technologies used in emergency management is assembled (communications, data management, logistics, etc.). The types of material collected is as follows, much of which was used to assist in the overall Risk Assessment section of this plan. A4a Government documents, including formal doctrine, frameworks and other broad federal and state level strategy and references. Also includes tactical references such as incident management handbooks and other National Incident Management System (NIMS) and Incident Command System (ICS) planning tools. Mitigation plans, including state, county, and municipal plans to mitigate the impacts of hazards. Emergency operations plans, including standing contingency plans for operations during an emergency at all levels of government as well as non‐government and private entities. Incident action plans, including specific operational period plans utilized at incident sites for upcoming operational periods. Also includes incident support plans developed at an Emergency Operations Centers that focus on upcoming operational phases. Continuity of operations plans, includes reference material related to government, industry, or organizational plans to continue. After action reviews, including hot‐wash notes, interviews, and other materials related to the lessons learned from emergency management responses, training, exercises, and allied activity. Such reports include, but are not limited to National Fire Academy reports, National Transportation Safety Board reports, Congressional commissions, and inquiries. Training and exercise materials, including materials related to capability assessment, training strategy, training and exercise development, scenario development and the conduct and evaluation of training and exercises. Technical documents, including but not restricted to census and demographic data, soil surveys, geological survey reports, USGS water supply papers, climate data, NOAA assessments and related materials. Also includes materials related to technical specialties and their employment in emergencies including Geographic Information Systems (GIS), Hazardous Materials (HAZMAT), radio communications, information systems, and social media/public affairs. Legal reference material, including references for the main tenants of emergency planning and management at the federal, state, and local levels, such as Public Laws, US Codes, Minnesota Statutes and County Board Resolutions. Maps and atlases, includes depictions of natural data in space and through time such as geology, soils, hydrology, topography, vegetation, and climate. Specific geological threats such as seismicity maps, flood plains, karst, and slope failure are also collected. The collection also includes human and cultural depictions such as population density, land use, 84 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 27 transportation, population density, critical infrastructure, income distribution, age demographics, key emergency facilities, and related information. Textbooks, including works on comparative emergency management, crisis leadership, emergency management organization, planning processes and tools, and specialized emergency planning as it relates to hospitals, public health, public works, libraries, utilities, schools, corporations, special events and other sectors. Also includes references on scientific data that is crucial for emergency management such as meteorology, hazardous materials, radiation, chemistry, microbiology, and other fields. Books, includes non‐fiction case studies on specific disasters, emergencies, and critical situations. Also includes projections and forecasts of the future natural, social, economic, and security environment. Historical materials, includes resources that describe historic emergencies, disasters and crisis and their underlying threats and hazards. Also traces the evolution of emergency planning, organization, response, and recovery. Photographs and imagery, includes still and moving photography and images on various formats including film and digital media involving all aspects of emergency management. Audio includes recordings of public warning messages, news reports, and radio transmissions involving disasters and emergency response. White Papers includes academic literature or articles pertaining to professional development, current practices, new theory, or forecasting trends in emergency management. Many times, this literature is available through search engines on the web (i.e., google scholar) 3.19 Public Involvement/ Engage the Public A3 Broad public participation in the planning process helps ensure that diverse points of view about the planning area’s needs are considered and addressed. 44CFR requires that the public have opportunities to comment on disaster mitigation and during the drafting stages and prior to plan approval. 3.20 Strategies to inform the public. Since this planning process involved an update for some planning partners and first‐time planning for others, HCEM continued to use a comprehensive outreach approach, using multiple media sources already established in participating jurisdictions and the County. The strategy for involving the public in this plan update emphasized the following elements: Use of social media (Facebook, X‐Twitter, Instagram, Nextdoor, and city websites) to provide information and seek input on the plan. Use a questionnaire to determine and identify the public’s perception of risk. Attempt to reach as many planning area residents using multiple media sources. Partner with Hennepin County’s Communication Division for a consistent message regarding the update to the HMP. Identify and involve planning area stakeholders to take part in wide dissemination. 85 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 28 The following graphic (GRAPHIC 3.20) is the initial invitation that was provided to all jurisdictions after doing a one‐week beta test with three communities. GRAPHIC 3.20 HCEM Hazard Mitigation Community Survey Who: Hennepin County Residents What: All Hazard Multi‐Jurisdictional Community Survey When: Launched December 1st, 2022, scheduled to end January 31st, 2023, May be extended Why: To provide a whole community option in mitigation participation through community websites and social media outlets Currently Launched: Links posted to HCEM Social Media (Facebook, Instagram, Twitter, Nextdoor) and on the HCEM website Responses as of Today: 64 Total Questions and Average Completion Time: 47 questions, about 23 minutes on average to complete Top three cities with the most participants: Crystal (15), Minneapolis (12), St. Louis Park (8) IMPORTANT: Our goal is to reach as many residents as possible in Hennepin County.

With Hennepin County and our communities’ ability to pass this information through their city websites, both Facebook and X (Twitter) were used to direct residents of Hennepin County to take part in this update by completing the survey questionnaire described below. It was determined to provide a link and QR code options to participate. We asked residents about their experiences about past disasters and their perception of hazard risks to Hennepin County. Residents were able to respond through an open survey period beginning December 1, 2022, and closed on March 31, 2023. To keep the messages consistent, the following social media messages were provided to all participating jurisdictions of this plan to provide wide dissemination during the open period. Digital media was the primary mechanism for the HMP release of information. A variety of press releases were provided through county and local community websites. The information provided included that an update was being conducted, that a survey was available, and links to the 2018 plan for review. For example, The University of Minnesota produced a mass e‐mail to their staff and student body describing what a HMP is, and asked students and staff to consider to participation. There were a variety of cities who also placed this information on their city websites.

Click here to take the survey What is Hazard Mitigation? Hazard Mitigation is any sustained action taken to reduce or eliminate long‐term risk to people and property from natural hazards, such as flooding, storms, high winds, wildfires, etc. Some examples include: ‐ Retrofitting water supply systems ‐ Stabilizing erosion hazard areas ‐ Elevating or retrofitting structures and utilities ‐ Building public safe rooms Mitigation efforts undertaken by communities help to minimize damage to buildings and infrastructure, as well as natural, cultural, and historic resources. Why Plan? Hazard Mitigation planning helps emergency management planners to identify the types of hazards that could affect Hennepin County. Hazard Mitigation planning also helps emergency managers and communities to identify actions that can help to reduce losses from those hazards. Ultimately, hazard mitigation planning helps to protect the residents of Hennepin County. Planning also helps to identify vulnerabilities and develop strategies to reduce the potential impacts of hazards. Building partnerships and reducing duplication of effort among organizations with similar goals is also a benefit of mitigation planning. In the end, Hazard Mitigation planning helps to build communities that are more resilient to disaster and increases public awareness of local hazards and disaster preparedness.

It also considered the 2022 FEMA guidance in creating questions to meet that criterion. The questionnaire was used to gauge household preparedness for natural hazards and the level of knowledge that residents have of hazards affecting Hennepin County. This questionnaire was hosted on several Hennepin County municipal social media and websites as well as posted to the Hennepin County Emergency Management Facebook and Twitter pages. The QR code and Link was also presented at monthly regional meetings and quarterly meetings as a reminder to point out the survey was “live”. Mitigation Planning Team members distributed the survey within their communities, with their local partners, and with their local vulnerable populations. A summary of the questionnaire results can be found below (3.24) under Public Involvement Results. The full questionnaire and results can be found in Section 7: Appendix C (page 69‐88) 3.23 Public involvement results From the questionnaire and feedback on social media posts, we found that the public is not aware that the county has a hazard mitigation plan but are aware of several natural hazards that affect them and the communities in Hennepin County. Major topics include Climate change, severe weather, and hail. 3.24 Stakeholder and Public Involvement Plan HCEM is committed to engaging stakeholders and the public in mitigation planning activities. To accomplish this, a Stakeholder and Public Involvement Plan was developed in 2015 which describes the approach, activities to engage stakeholders and the public in the development of the HMP. Based on current Federal requirements, a Mitigation Plan must include adequate and reasonable notice and opportunity for comment and other input from a variety of stakeholders, including the public, local governments, and other interested parties. HCEM has sought comment and the involvement of these stakeholders and the public through planning forums and questionnaires, interviews, as well as an online survey. Outreach activities were conducted as part of the 2024 HMP. These activities sought input and comments on the overall vision and direction for Hennepin County Emergency Management to meet the federal and state requirements, as well as consider local level development and participation in planning. This HMP determines both short and long‐range mitigation needs in community improvement and integrates within the scope of long‐range planning with HSEM‐ State of Minnesota. 3.25 Goals for Stakeholder and Public Involvement: The goals for stakeholder and public involvement for this HMP: • Gain an understanding of the need, the potential impacts of and opportunities for this HMP to improve the overall efficiency and sustainability of our communities • Solicit input relative to mitigation policies, projects, and programs to better meet the needs of communities while also making Hennepin County a more attractive location to conduct business and a better place to live; and • Provide input for developing a strategy for making investment decisions to mitigate risk. 89 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 32 3.26 Outreach Activities and Participation A. Open Houses/Regional Meetings/Quarterly Meetings HCEM held five plan review teams meetings. At each, a short presentation was given providing community visits, completion timelines, and survey results. Following each presentation was a discussion period and a brief question and answer period. HCEM attended all monthly regional planning group meetings (North, South, Lakes, and Minneapolis) to provide updates, instruction and receive feedback from these groups. HCEM would also meet with individual communities throughout this process. B. Survey Questionnaire The public through each of the 42 municipalities were given the opportunity to complete the HMP survey. Invitations were sent by email, social media, presented in county and local meetings, and available through local and the HCEM websites. Multiple reminders were sent to local emergency managers to promote wide dissemination. The survey was posted through survey monkey. The survey not only had questions about overall needs improve, but also questions about specific demographic information. Local jurisdictions ensured that this survey was available to underserved and socially vulnerable populations within their geographic area. 90 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 33 SECTION 4 COUNTY PROFILE 4.1.

Physical Features Hennepin County landforms were formed in the recent geological past by the action of glaciers that receded from the area about 10,000 years ago. The surface of the county may be classed into three broad types. Smooth plains of outwash and river terraces are found especially in the northeast. Belts of hills and gently rolling plains are interspersed throughout the rest of the county. Drainage is dominated by the Mississippi River into which all other Hennepin County streams empty, either directly or indirectly. The next major river is the Minnesota which forms the southern boundary of the County. The Crow River forms the northwest boundary of the County. Seven other important streams course through the county. The southwest portion of Hennepin County is dominated by Lake Minnetonka, a 14,528‐acre (59 square kilometer) body of water. Area: Hennepin County has an area of 607 square miles (1,572 square kilometers) Land area: 554 square miles (1,435 square kilometers) or 91% Water area: 53 square miles (137 square kilometers) or 9% Physical features: Mean elevation is 925 feet (282 meters) above sea level.

Infrastructure Hennepin County has a well‐developed highway system. The Hennepin County Highway System consists of approximately 571 miles of roadway. The Highway System is divided into two categories: County State Aid Highways and County Roads. The County Road system consists of approximately 80 miles of roadway. Metro Transit in Minneapolis recorded more than 42 million rides across all light rail, bus, and paratransit services in 2022, up 17% compared with total ridership in 2021. Light‐rail ridership increased 16% year over year with more than 12 million riders. Xcel Energy, Wright‐Hennepin Electric and Minnesota Valley Electric are public utility companies that provide natural gas and electric service to over 1 million residents in Hennepin County. Maintaining an adequate supply of safe drinking water requires attention, investment, and responses to new and ongoing challenges. Sustainable water resources are critical to personal and public health as well as our economy. Protecting water sources, treating water, and testing water after it is treated are part of the multi‐barrier approach to assuring an adequate supply of water that is safe to drink. The Minnesota Department of Health protects our drinking water. 4.7. Land Cover (see Section 7, Appendix 6‐ Community Map Series, Geography) Hennepin County consist of 388,100 acres of land that is divided into the following land cover: Artificial Surfaces and Associated Areas Planted or Cultivated Vegetation Forests Woodlands Shrublands Herbaceous Nonvascular Vegetation Sparse Vegetation Water 95 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 38 4.8. Watersheds (see Section 7, Appendix 6‐ Community Map Series, Bodies of Water) Watersheds are managed by either a Watershed Management Organization or a Watershed District. Both are considered a separate unit of government and are governed by a Board of Commissioners. Watershed District board members are appointed by the Hennepin County Commissioners, while Watershed Management Organization board members are appointed by individual city councils. Metro watershed management plans address: protection, preservation, and use natural surface and groundwater storage and retention systems. minimize public capital expenditures needed to correct flooding and water quality problems. identify and plan for means to effectively protect and improve surface and groundwater quality. establish more uniform local policies and official controls for surface and groundwater management. prevent erosion of soil into surface water systems. promote groundwater recharge. protect and enhance fish and wildlife habitat and water recreational facilities; and secure the other benefits associated with the proper management of surface and groundwater. Watershed organizations in Hennepin County are: Bassett Creek Watershed Management Commission Elm Creek Watershed Management Commission Lower Minnesota River Watershed District Minnehaha Creek Watershed District Mississippi Watershed Management Organization Nine Mile Creek Watershed District Pioneer‐Sarah Creek Watershed Management Commission Richfield‐Bloomington Watershed Management Organization Riley Purgatory Bluff Creek Watershed District Shingle Creek Watershed Management Commission West Mississippi River Watershed Management Commission 4.9. School Districts (see Section 7, Appendix 6‐ Community Map Series, School Districts) There are 22 independent school districts in Hennepin County, two of which were part of the Mitigation Planning Team. The following is a table of those Districts. Hennepin County Independent School Districts Special ISD 1 ‐ Minneapolis ISD 279 – Osseo ISD 011 ‐ Anoka‐Hennepin ISD 280 – Richfield ISD 110 – Waconia ISD 281 – Robbinsdale ISD 111 – Watertown‐Mayer ISD 282 – St. Anthony ISD 270 – Hopkins ISD 283 – St. Louis Park ISD 271 – Bloomington ISD 284 ‐ Wayzata ISD 272 – Eden Prairie ISD 286 – Brooklyn Center 96 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 39 ISD 273 – Edina ISD 728 – Elk River ISD 276 – Minnetonka ISD 877 – Buffalo ISD 277 ‐ Westonka ISD 879 – Delano ISD 278 ‐ Orono ISD 883 ‐ Rockford 4.10. Future Community Trends for 2040 Hennepin County is facing many changes from shifts in travel behavior, demographics, technology, and the environment. These shifts will affect how people, goods, and information move in the future. It is important that we proactively plan to address these changes to achieve our transportation vision. In anticipation of how community comprehensive plans will be structured for business development, residential infrastructure, and improvement to transportation corridors It is expected that partnerships will provide information at to the changes that will affect future hazard mitigation planning. Those city officials and planners involved in this work tend to share or extrapolate existing community development patterns providing information required in identifying areas of concern. Generally, the short‐term five‐ to‐ten‐year period has built in predictability with routine accuracy since change is often smaller and the lead‐time of most large‐scale projects require that planning preparations are scheduled well in advance. Longer‐term projections or immediate disaster impact planning are much more difficult since land use policy, lifestyle shifts/attitudes, economic patterns and other actions affecting society are hard to foresee. Strategic investments and partnerships that leverage geographic diversity, infrastructure, the strength of the local economy, and increasingly diverse human capital are essential to the continued success and wellbeing of Hennepin County and its residents. Socio‐economic Population growth will continue with an increase of 100K new residents. Countywide will see an increase in 50K households. Acknowledging Disparity People of color in Minnesota and Hennepin County are more likely to use public transportation and are also more likely to spend 30+ minutes commuting to work compared to their white counterparts. Challenge: Provide a multimodal transportation system that is affordable and accessible to reduce the cost of transportation for cost‐burdened households. We also must ensure that shared mobility and other technological advances are available to all residents regardless of economic status. The County will continue to grow more racially and ethnically diverse. Migration and birth rates continue to move the county toward a less homogeneous people. This will bring different expectations of the county and the region. Aging Population Meeting the needs of an older population will require adjusting our services and infrastructure. In 1990, 1 in 10 Hennepin County residents were aged 65 or older. By 2040, it is estimated this will increase to 1 in 3 residents. Challenge: Create a transportation system that provides safe, accessible, and affordable transportation options to enable our growing senior population to age in place and remain healthy, active, and socially connected. 97 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 40 We will experience an aging population. Meeting the needs of an older population will require adjusting our services and infrastructure. An older population may work less overall but also has more time and expertise to share. Climate Change Increased temperature variation, precipitation levels, and the frequency of extreme weather events are impacting design, construction, maintenance, and operations of our transportation system resulting in increased lifecycle costs. Challenge: We will need to explore emerging technologies and employ innovative practices to reduce the impact of the transportation system on the air we breathe, the water we drink, and the natural resources we enjoy. Weather pattern change will force adaptation in our infrastructure, services, and society. The county will also face pressure to reduce its contribution to climate change. Economy Economic growth in Hennepin County depends on an efficient, reliable, and affordable transportation system to maintain competitive commute times, retain, and attract businesses, and support efficient movement of freight. Challenge: Use technology and innovation to support economic growth and personal and freight mobility by making more efficient use of the transportation system and preserving and maintaining our aging infrastructure. Technology is enabling the rise of a sharing economy and is redefining what work is. No longer will we build one thing for everyone, and many products won’t be physical. The workforce is becoming highly connected and mobile. Infrastructure More than 30% of our roads are more than 50 years old and are nearing the end of their useful life. Ongoing maintenance, rehab and replacement is estimated to cost $2 billion. Challenge: As we rehab and replace infrastructure, we need to explore new ways to incorporate new technologies, innovations, and adaptations. Technology Technology is enabling the rise of a sharing economy and is redefining how, where, and when we work, travel, and communicate. The transportation sector is relying on data to drive decisions, and on technology to reimagine how we move people and goods. Mobile access to everything from traffic data to transit schedules informs our travel choices. Technological advances are changing residents’ lives and how the county does business and the services we provide. Challenge: While technological advancements have the potential to improve safety, mobility, and efficiency, we must recognize that without proactive planning and policy interventions, the technologies could result in increasing sprawl, vehicle miles traveled (VMT), and greenhouse gas (GHG) emissions, and limiting access for disadvantaged communities. Artificial Intelligence and Generative pre‐trained transformers have opened avenues with deep learning and machine learning and have positive and negative implication in its use. 98 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 41 Transportation Preferences are changing. In the region, people are driving less, using a variety of transportation modes, and showing a clear preference for living in walkable, transit‐accessible neighborhoods. Challenge: Hennepin County residents expect new and diverse mobility options that are affordable and available throughout the county. Mobility is rapidly evolving. Options for how we travel are expanding and our preferences are changing, too. The sharing economy, transit, and autonomous vehicles have the potential to profoundly and rapidly change how people get around. What we do today might not align with future mobility needs. Our infrastructure is aging. Many of our systems were built in the second half of the 20th century. That infrastructure needs maintenance, but society has not budgeted for it. There are opportunities to rethink these systems as we rebuild, incorporating new goals and technologies. Local land use development patterns E1a The principal guide in the forecasting of future land use development is with the comprehensive plans of the individual Hennepin County municipalities. All 45 municipalities provide future land development information on what types of land uses and the intensities of development they expect over the next twenty years. Land use planning, designations, and zoning are vested in the authority of individual municipalities. Hennepin County will continue to collaborate with these agencies during activities such as development reviews, corridor studies, and project improvements to encourage increased development densities, expanded access to transit, transit corridor and station area planning. Hennepin County actively promotes specific types of land use and development, including TOD, affordable housing, and brownfield redevelopment through the incentive‐based funding programs, Transit‐Oriented Development, Affordable Housing Incentive Fund, and the Environmental Response Fund, respectively. 99 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 42 THIS PAGE WAS INTENTIONALLY LEFT BLANK 100 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 43 SECTION 5 COMMUNITY CAPABILITY ASSESSMENT 5.1. Community Planning Tool Assessment C1a, C1b Hennepin County Emergency Management (HCEM) uses a variety of hazard mitigation implements to assist local emergency managers identify additional capability that can be used to pay down risk. The capability tables are meant to be informative with an understanding to build or be aware of plan sets, programs, relationships, funding, training, and regulation. This capability assessment provides overall awareness and can leverage what a community could draw from in making decisions about mitigation actions or significant events. With respect to each community‐ each community determines their capability and should consider closing any gaps if they come across an area not identified as a capability. The capability listings in this section enables emergency managers a program to improve community resilience through actions taken before, during and after a significant event that is within local capabilities. For example, building codes, land use, development ordinances, and regulations are commonly used which control rate of growth and limit development into flood prone areas. This 2024 Plan update includes Hennepin County’s second HMP capability assessment. This assessment was conducted using responses to the City Capabilities Questionnaire that was distributed to all Hennepin County municipalities. Local emergency managers from each participating jurisdiction were directed to update the City Capabilities matrix. Capabilities were categorized into planning (TABLE 5.1A), administrative and technical (TABLE 5.1B), fiscal (TABLE 5.1C) and education and training (TABLE 5.1D). In addition, a new, Ordinance and Regulation section (TABLE 5.1E) was developed and added to this HMP revision. 101 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 44 The results of the capability assessment are presented in the following tables.

All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 49 5.2. Participation in the National Flood Insurance Program C2a Flooding is the most common natural hazard. In 1968, Congress created the National Flood Insurance Program (NFIP) in response to the rising cost of taxpayer funded disaster relief for flood victims and the increasing amount of damage caused by floods. The Federal Emergency Management Agency (FEMA) manages the NFIP and oversees the floodplain management and mapping components of the Program. Nearly 20,000 communities across the United States and its territories participate in the NFIP by adopting and enforcing floodplain management ordinances to reduce future flood damage. In exchange, the NFIP makes federally backed flood insurance available to homeowners, renters, and business owners in these communities. The National Flood Insurance Program aims to reduce the impact of flooding on private and public structures. It does so by providing affordable insurance to property owners and by encouraging communities to adopt and enforce floodplain management regulations. These efforts help mitigate the effects of flooding on new and improved structures. Overall, the program reduces the socio‐economic impact of disasters by promoting the purchase and retention of general risk insurance, but also of flood insurance, specifically. 5.3 National Flood Insurance Program in Minnesota C2a The Minnesota Department of Natural Resources (DNR) is the state administration agent for the NFIP in Minnesota. The HSEM Hazard Mitigation branch works with the DNR, FEMA other agencies to help communities develop effective local flood hazard mitigation plans and projects which includes adopting required ordnances and mitigation plans necessary for the community to be eligible to participate in the NFIP.

A Repetitive loss property may or may not be currently insurance by the NFIP. 111 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 54 TABLE 5.4: Hennepin County Repetitive Loss Properties by Jurisdiction Jurisdiction Number of Repetitive Loss Properties Type of Property Bloomington 1 Residential Brooklyn Park 1 Residential Dayton 1 Residential Edina 5 Residential Golden Valley 2 Residential Hopkins 1 Residential Medicine Lake 1 Residential Minneapolis 7 Residential Mound 1 Residential New Hope 1 Residential Orono 1 Residential Plymouth 1 Residential Robbinsdale 1 Residential Saint Louis Park 1 Residential Tonka Bay 1 Residential Wayzata 2 Residential 5.5 Community Rating System (CRS) There are currently 0 Hennepin County municipalities that participate in the Community Rating System (CRS). The Community Rating System (CRS) recognizes and encourages community floodplain management activities that exceed the minimum NFIP standards. Depending upon the level of participation, flood insurance premium rates for policyholders can be reduced up to 45%. Besides the benefit of reduced insurance rates, CRS floodplain management activities enhance public safety, reduce damages to property and public infrastructure, avoid economic disruption and losses, reduce human suffering, and protect the environment. Technical assistance on designing and implementing some activities is available at no charge. Participating in the CRS provides an incentive to maintaining and improving a community's floodplain management program over the years. Implementing some CRS activities can help projects qualify for certain other Federal assistance programs. In exchange for a community's proactive efforts to reduce flood risk, policyholders can receive reduced flood insurance premiums for buildings in the community. These reduced premiums reflect the reduced flood risk resulting from community efforts toward achieving the three CRS goals: 1. Reduce flood damage to insurable property. 2. Strengthen and support the insurance aspects of the NFIP. 3. Encourage a comprehensive approach to floodplain management. Participation in the Community Rating System (CRS) is voluntary. By participating, communities earn credit points that determine classifications. There are 10 CRS Classes: Class 1 requires the most credit points and provides the largest flood insurance premium reduction (45 percent), while Class 10 means the community does not participate in the CRS or has not earned the minimum required credit points, and 112 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 55 residents receive no premium reduction. The CRS Classes are based on completion of 19 creditable activities organized into 4 categories: 1. Public Information 2. Mapping and Regulations 3. Flood Damage Reduction 4. Warning and Response 113 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 56 THIS PAGE WAS INTENTIONALLY LEFT BLANK 114 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 57 SECTION 6 HAZARD MITIGATION PLAN MAINTENANCE D This section describes the system that Hennepin County and participating jurisdictions have established to monitor, evaluate, and update the HMP; implement the mitigation plan through existing programs; and solicit continued public involvement with plan maintenance. 6.1. Monitoring, Evaluating, and Updating the Plan D1, D2 This section of the plan describes the ongoing methods to keep the plan current. It describes how the plan will be reviewed annually, how the public will be kept involved, and how the plan will be integrated into other planning mechanisms. It details the formal process that will ensure that this HMP remains an active and relevant document. The plan maintenance process includes a schedule for monitoring and evaluating the plan annually, as well as revising it every five years. This section also describes how the county will integrate public participation throughout the plan maintenance process. Minimum changes have been made to these processes since the 2018 plan adoption. However, COVID‐ 19 did change the way meetings were conducted. Many meetings were put on hold. Remote and hybrid work were eventually developed which still delayed much of the maintenance work as minimal representation attended these annual review meetings. Additional information will be presented at the Hennepin Emergency Managers Community quarterly meeting. 6.1.1. Monitoring D2a, D2b HCEM is tasked with the overall responsibility of monitoring this HMP. HCEM will develop a Local Mitigation Strategy Working Group (LMS). The HMP project will continually be under review as FEMA guidance is always evolving. This guidance will inform participants of funding sources, current project considerations for application, and assist in prioritizing funding availability for participating jurisdictions. By monitoring the implementation of the plan, HCEM and the LMS will be able to assess which projects are moving forward, which projects we be delayed, which have been completed, and which are no longer feasible or require additional planning as they no longer meet federal or state criteria. Finally, the LMS will periodically inform the public about the progress and success of its efforts through various community website or social media platforms. The LMS will continue to meet regularly and communicate via email. As part of the monitoring, evaluation and enhancement process, a participating jurisdiction meeting will be held in the 3rd Quarter (Jul, Aug, Sept) annually, to create a best practice program. The LMS will be able to address the following: FEMA updates, State updates, grant updates, and the application process. Attendance and minutes must be kept supporting this HMP update in future revisions. 6.1.2. Evaluation D2b Plan recommendations will be reviewed at the annual LMS meeting. The meeting will be used to determine the effectiveness of mitigation plan programs and make changes that may affect mitigation projects, priorities, or funding sources. As part of the evaluation process, responsible agencies will be invited to share any updates on their mitigation projects at the meeting. In addition, the following questions will be asked: Are there any new hazards developed not addressed in the plan? 115 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 58 Have any communities experienced natural disasters that will need to be added in the plan? Have any unanticipated developments occurred that is vulnerable to hazards (CIKR, zoning, land use)? Are there any additional mitigation ideas that need to be incorporated? What projects are being considered, been initiated, and or completed? What are the barriers to completing projects identified in the plan? Are our HMP goals still reflective of community priorities to reduce hazard vulnerabilities? Is there an open Presidential Disaster Declaration that has made mitigation monies available? The purpose of these questions is to gauge community partners goals, objectives, and actions and if they are still current and what changes need to be made in the plan. An update will be required at the annual meeting and can be submitted any time to HCEM. The discussion will be documented so that when the plan is revised, findings can be considered or incorporated in the next five‐year plan revision. Finally, the LMS will also evaluate how overall strategies and policies that drive augmentation, revision, or implementation. Programs and policies for review may include but not limited to: Sustainability Critical Infrastructure Climate initiatives Underserved populations Economic Growth Growth Management Environmental Preservation Historic Preservation Redevelopment Health and/or safety Recreation Land use/zoning Public Education and Outreach Transportation Technology 6.1.3. Updating the Plan D2c HCEM receives a one‐year notification from Minnesota’s Homeland Security Emergency Management‐ State Hazard Mitigation Officer. This notification indicates that the current adopted plan will expire in approximately one year. This is the official notice to begin modifying the HMP. Any of the following situations could trigger a review and update of the plan: Occurrence of a major natural disaster in Hennepin County Five‐year plan expiration Change in state of federal regulations which direct or guide compliance. The HMP will be periodically reviewed and updated by HCEM every five years unless it has undergone a more recent revision (with associated FEMA approval). At the five‐year mark, several 116 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 59 questions will be asked: Do the goals address current and expected conditions? Meet the FEMA guidance elements list. Has risk changed for participating jurisdictions? What additional hazard events have occurred or have been tracked between the five‐year planning period? Have the community capabilities changed with planning, administrative and technical, fiscal, training and education, and regulation and ordinance? What progress has been made to complete mitigation actions? How has the public remained involved over the past five years? Have a participating jurisdictions critical infrastructure prioritization changed (CFI 1‐5) 6.2. Five Year Revision Procedure When a major natural disaster occurs in Hennepin County, the staff from HCEM and the LMS working group will meet following the recovery effort to review and determine if changes will be required to the HMP. In the absence of a major natural disaster, the five‐year review will take place during the 12‐month period preceding the State of Minnesota HSEM plan expiration notification letter. Following proper notification for record, the Hennepin County Emergency Management Plans & Systems Integration Coordinator will convene a review committee, and with their assistance, carry out the following tasks: Create a timeline for completion. Determine if current goals are still valid? Meet one on one with each jurisdiction. Review community capability data. Compare historical hazards against local critical infrastructure. Prioritize continuity by identifying priority 1 critical facilities. Develop a mitigation projects list that would bring value and pay down risk for participating jurisdictions. Prepare a final draft. Submit to HSEM for FEMA element crosswalk compliance. Present to County Board for Adoption and submit adoption to State and FEMA Complete the participating jurisdiction plan adoption/resolution process and submit those by city resolutions to State and FEMA Receive FEMA approval letters for all participating jurisdictions. 6.3. Public Involvement D1a The public is encouraged to be involved in the continual updates of the HMP. The following methods of public involvement are options to ensure they are successful in having access. As technology or accessibility matures, additional methods of public involvement will be implemented. For the previous 2018 plan, a redacted plan was available on Hennepin County’s website for the past 5 years. An unredacted copy was provided to participating jurisdictions, departments, elected officials, and partner agencies. HCEM will continue to be the lead agency to ensure the public remains involved over the next five years via the following methods: HCEM will use social media via Facebook and Twitter to inform the public as to the availability of information and draft plan documents for review. This platform will be used extensively going 117 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 60 forward in engaging the public in ongoing hazard mitigation planning for public awareness. Each jurisdiction having a dedicated website can post a redacted HMP as received from the Plans & Systems Integration Coordinator for public consumption. The HC link can also be shared on their city web page, or a redacted copy can be imported into a city web site. HCEM and LMS working group will lead efforts to prepare and disseminate an annual fact sheet on status of hazard mitigation planning and implementation to all stakeholders. These materials will be passed out at various community engagement activities, regional planning working group meetings, and at Hennepin Emergency Management Community quarterly meetings. HCEM will continue to create a survey for the public that asks for feedback regarding their understanding of hazard mitigation and various hazards in their communities. These survey forms will be shared with participating jurisdictions for their use as well. These surveys will be distributed at various community engagement activities. 6.4. Implementation of the HMP through Existing Programs and Plans A4a, D3 All participating jurisdictions will need to integrate this HMP into relevant government decision‐making processes or mechanisms, where feasible. This includes integrating the recommendations or actions of this HMP into other local planning strategies, processes, or by using local comprehensive or capital improvement plans, as a project bridge, where funding may be allocated from multi sources. All jurisdictions must be cognizant of their objectives and actions in that they do not increase hazard vulnerability in Hennepin County. Although it is recognized that there are many possible benefits to integrating components of this Plan into other local planning strategy, the development and maintenance of this stand‐alone HMP is very effective and an appropriate method ensuring successful implementation of local hazard mitigation projects. TABLE 6‐4A below includes existing processes and programs through which the HMP could be implemented. These processes and programs can also integrate this plan into their planning mechanisms.

To access the questionnaire, participants were provided an informed consent form letting them know that their information was voluntary, that any free response questions were optional, and that the results would be published as part of the 2024 HMP. We also wanted to know how many respondents knew that a Hazard Mitigation Plan existed. 78% of the respondents did not know the plan existed. This shows that just by participating in the questionnaire, people were learning about mitigation. The survey asked if they were residents of Hennepin County. Of the 329 responses, 18 indicated they did not reside in Hennepin County. 131 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 74 The next few questions pertained to residency, employment, and city of employment. The city with the highest participation was Brooklyn Center at 22 %, second was Crystal with 12%. We had participants from 30 of the 47 cities to include Fort Snelling and one choosing “prefer not to answer” in Hennepin County. 132 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 75 An overwhelming 65% of the respondents have lived in Hennepin County 20 or more years. 57% responded that they work within Hennepin County. 133 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 76 Survey participants worked in 29 different cities with 14% of the respondents working in Minneapolis. 134 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 77 Some personal information was asked.

The details provided by each community that fall within the scope of this plan are provided in this appendix. E.1: Champlin The City has experienced moderate commercial and residential development over the past few years. The residential development was mainly single‐family residential subdivisions. None of the new development has been into any hazard prone areas or has affected vulnerable populations. E.2: Dayton The City of Dayton has seen enormous growth in residential and commercial properties. However, that growth has yet to be in any hazard‐prone areas within the community, such as floodplains, and it has yet to impact vulnerable populations within the community. E.3: Edina Over the past 5 years the City has approved several large scale re‐developments. As these sites were already developed, there was no impacts on wetland, floodplains or hazard prone areas. There have not been any developments that have affected vulnerable populations. Each site was reviewed by City staff and consultants when necessary and found not to have negative impacts. The following projects have been approved and built: 8 unit townhome replaced a 5‐unit townhome at 5132 Hankerson Avenue; 21‐ unit apartment replaced a day care at 4425 Valley View Road; a 118‐unit senior apartment replace an office building at 4040 70th Street; a 408 unit apartment replaced a large office building at 4660 77th Street; A 200 unit apartment replaced an office building at 4911 77th Street; A 196 unit apartment replaced an office and Perkins at 4917 Eden Avenue; 24,000 square foot medical office replaced a 16,000 s.f. medical office at 6500 Barrie Road; New restaurant, indoor tennis courts and fitness center built at Interlachen Country Club, 6200 Interlachen Blvd.; A 276 unit apartment replaced an office building at 4600 77th Street; 4‐unit townhome replaced a beauty salon at 4404 Valley View Road; Church and school expansion at 5051 Eden Avenue; 3‐story furniture store and restaurant built in the parking lot at Southdale; 70‐unit apartment replaced a large recording studio at 4100 76th Street; 62 unit apartment replaced a laundromat at 7075 Amundson Avenue; A 10,000 square feet retail building replaced an office building at 6950 France; A 167 unit apartment replaced a retail building at 3650 Hazelton Road. E.4: Loretto The Chippewa Estates Development was completed between 2018‐2020 and consists of four single‐ family residential homes. No part of this development is in a hazard prone area, nor did it affect vulnerable populations. E.5: Maple Grove The City of Maple Grove is a fast‐growing community with a number of large areas undergoing rapid development. Highlights include development of residential neighborhoods in the area of 105th Avenue, 173 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 116 construction of a large new headquarters building for Boston Scientific, residential neighborhoods in the vicinity of the Hindu Temple north of Arbor Ridge Parkway (101st Avenue), as well as numerous other residential and commercial buildings of various sizes. Maple Grove works within a comprehensive master plan in coordination with the Metropolitan Council and the State of Minnesota to ensure that new development has minimal effect on vulnerable populations and limited exposure to hazard prone areas. Maple Grove ‐ 105th Avenue Master Plan In 2018, the City of Maple Grove initiated a planning process to guide future development in the 105th Avenue North Growth Area. The study area is generally defined by Interstate 94 to the west, Interstate 610 to the south, County Road 81 and the rail line to the north, and Fernbrook Lane to the east. Core objectives of the 105th Avenue North Growth Area Master Plan were to examine alternatives for land uses, parks, trails and open space features and guide the design of the infrastructure network needed to support the desired development. Additionally, another key objective was also to understand the desires of existing landowners in the study area, some of whom are interested in developing their property and others, primarily existing single‐family residences, who are interested in remaining. Finding the right balance for new development, identifying what uses will likely remain, providing future opportunities for land uses to transition over time, was fundamental to the success of the Master Plan. The study area includes a variety of development areas, or districts, each with their own unique physical characteristics and development and/or redevelopment potential. In order to understand and address the many facets influencing development in the 105th Avenue North Growth Area, the planning team worked to understand current and future market conditions, existing and currently proposed land uses, potential transportation enhancements (vehicular, bicycle and pedestrian) and to identify necessary parks and open space features. Maple Grove – Gravel Mining Area South Master Plan The GMA South study area is just over 400 acres. Located north of Interstate 94 and west of US Highway 169. Elm Creek Boulevard bisects the northern portions of the plan area. The existing land uses within the GMA south area principally material extraction and industrial. Surrounding land uses include regional‐scale commercial to the west, and low‐density residential to the south across I‐94. Ownership of the parcels within the GMA South area is limited to a handful of entities. According to the most recent comprehensive plans for Maple Grove and Brooklyn Park, the area surrounding the gravel mining area south is envisioned for a wide range of uses. Commercial uses (Arbor Lakes) are well established to the west and industrial use is expected to continue to the north. Housing is planned to the west of the parkway shown north of the GMA area. A large business park to the east across 169 (in Brooklyn Park) is planned to continue. An established neighborhood is located to the south across I‐94, with some mixed use area available adjacent to the highway. Maple Grove – Northwest ‐ 610 Master Plan Existing land uses within the study area primarily consist of agricultural uses and undeveloped open space. Approximately a dozen rural residences and farmsteads dot the study area. A 20‐acre parcel 174 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 117 containing the Minneapolis Northwest KOA campground and RV Park is located along Brockton Lane/County Road 101. The Hindu Society of Minnesota owns approximately 80 acres within the study area, which includes a Hindu temple facility. Adjoining land uses within Maple Grove City limits include a combination of single‐family and townhome residences to the south within the Delgany Neighborhood. Areas further to the southeast, include commercial and retail uses primarily within the Maple Commons development. Directly west and across I‐94, land uses are similar to those within the study area, consisting of primarily undeveloped open areas, with larger‐lot single‐family residences. The City’s proposed 2018 Land Use plan designates the study area primarily low‐medium density residential. Higher density residential categories are identified within the Hindu Society property in recognition of their campus master plan. An additional area identified for highdensity residential is located at the intersection of 105th and 101st Avenues. Areas east of 105th Ave and Lawndale Lane are designated as mixed use, envisioned to contain a mix of residential, office, and office‐warehouse uses primarily. The school district property is identified as a future public use. E.6: Medicine Lake Medicine Lake is making long‐term improvements to critical infrastructure beginning in the summer of 2024. These projects include complete reconstruction of all streets within the city of Medicine Lake, municipal water main installation, sanitary sewer upgrades, and lift station reconstruction. Each of these projects will impact all residents of Medicine Lake. E.7: Medina Recent residential development activity in Medina has included single‐family and townhome development concentrated north of Highway 55. Commercial development included the new Adam’s Pest Control office building and Loram Warehouse development. Okalee, a new senior housing/assisted living facility has also been constructed and the Wealshire Memory Care facility has been expanded, both housing populations with service needs. Development and construction have not been in hazard prone areas. E.8: Minneapolis Minneapolis recently received an application for an addition to an existing home in the floodplain. An existing home at 4845 James in the FP overlay and AE floodway proposed a building addition. They received a CUP to build the addition on pilings as opposed to on fill, which would have been permitted by code as of right. The proposed floor elevations were above the base flood elevation. No other development that is of relevance to the hazard mitigation plan occurred. E.9: Minnetrista The Woodland Cove development has progressed over the past several years in the area just north of Hwy 7 at Kings Point Road. It includes a variety of housing ranging from townhouses, villa homes, single family homes and multi‐million dollar lake homes. Within the past year or so we have added commercial property to include a grocery store, Caribou Coffee, a liquor store and a several hundred unit apartment complex. Additionally, there are a couple other areas in the city currently zoned for multi‐family development. None of these areas are prone to hazards. 175 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 118 E.10: New Hope As an inner‐ring suburb of Minneapolis, the city of New Hope is largely developed, with limited opportunities for further development. However, New Hope continues to pursue opportunities for redevelopment in all areas and has seen growth in commercial, industrial, and single‐family housing areas, despite some slowing during the COVID19 pandemic. Single‐family home values have risen steadily the past few years, increasingly the valuation of property for homeowners and slowly growing the overall tax base of the city. The city’s population has held steady around the 21,000 mark for several years, and population diversity remains relatively steady year‐over‐year. A new consideration for the community to incorporate into vulnerability planning is the addition of a new residential development. This development was completed on a 8.7 acre site, consisting of 32 single‐family homes near a known Burlington Northern Santa Fe (BNSF) freight railway, which does transport hazardous materials, including crude oil. Continued development and redevelopment near this transport site is a consideration going forward. E.11: Plymouth The City of Plymouth has recently developed the Hollydale Golf Course into a residential neighborhood. This 160‐acre development is located east of Holly Lane N between the 4600‐block and the 5900‐block. There are 231 lots for single family homesThere are no hazard prone areas in this new development. Enclave mixed use project is currently under construction. The property is located along Bass Lake Rd, west of Hwy 169 and consists of 19 acres. The project will contain commercial, office and mixed use retail/residential. There are no known hazard prone areas in this development. Parkera and Twin Cities Orthopedics: is currently under construction and is a redevelopment site of Dundee Nursery. The site was remediated during initial construction and there are no known hazards. When complete the site will have a 70,00 Square Foot medical building (complete/TCO) and a 210 unit multi‐family building with 428 parking spaces (bus transit). E.12: Robbinsdale Recent development in Robbinsdale can be characterized as redevelopment of obsolescent or underutilized commercial and office properties for high density multiple family uses. No building occurred in any hazard prone areas and there was no impact to vulnerable populations. E.13: Rogers Residential Development The City has seen approximately 2000 new single family lots be platted/subdivided (available for construction, not necessarily built) over the past 5 years. New Single Family and Townhome permits 265 new homes (single/townhomes) constructed in 2023. 226 in 2022 256 in 2021 141 in 2020 83 in 2019 Apartments 2019‐2021 – Vincent Woods apartments constructed with 165 units. 176 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 1‐ Background and County Profile 119 2022 ‐ The Frederik apartments were constructed with approximately 175 units. 2023 ‐ Territorial Lofts constructed on Territorial Road, 75 units 2022 ‐ Quest Apartments constructed on 137th Avenue North, 135 units. Commercial Development Endeavor Distribution Center (Brockton Lane) Graco expansion, 440,000 sq ft of industrial expansion of existing Graco facility. (David Koch) Capitol Beverage Expansion (South Diamond Lake Rd) Freddy’s/Dunkin strip mall (Main Street) 21st Century Bank (Rogers Drive) I‐State Trucking (CR81) Rogers Tennis Club (James Rd) Primrose Daycare (South Diamond Lake Rd) Construction of Norbella Senior Living and Memory Care development (40 units) could introduce new vulnerable populations to the community on South Diamond Lake Road. No recent developments are in a floodplain. 177 2024 HENNEPIN COUNTY MULTI‐JURISDICTIONAL HAZARD MITIGATION PLAN VOLUME 2 Hazard Inventory 01 February 2024 178 THIS PAGE WAS INTENTIONALLY LEFT BLANK 179 TABLE OF CONTENTS- VOLUME 2 TABLE OF CONTENTS .......................................................................................................................... 3 SECTION 1: HAZARD CATEGORIES AND INCLUSIONS ...................................................................... 5 1.1.

Risk Assessment Process Risk from natural hazards is a combination of hazard and vulnerability. The risk assessment process measures the potential loss to a community, including loss of life, personal injury, property damage and economic injury resulting from a hazard event. The risk assessment process allows a community to better understand their potential risk and associated vulnerability to natural, intentional human‐caused and unintentional human‐caused hazards. This information provides the framework for a community to develop and prioritize mitigation strategies and plans to help reduce both the risk and vulnerability from future hazard events. This section describes the natural hazards that have had historical impact within Hennepin County and assesses their associated risk with future impact. There are 19 hazards that have affected Hennepin County and are identified and defined in terms of their range of magnitude, spectrum of consequences, potential for cascading effects, geographic scope of hazard, historical occurrences, and likelihood of future occurrences. There were no hazards eliminated in this revision TABLE 1.1A was created to meet FEMA guidance. TABLE 1.1A B1a Eliminated Hazards in 2024 There were no hazards eliminated in this revision In addition, a thorough geospatial risk analysis was conducted using locally available parcel data and building values. Further, maps were provided where hazard boundaries and data existed. These improvements help to provide a more accurate assessment of risk in the county to develop mitigation actions. 1.1.2. FEMA Risk Assessment Tool Limitations In 1997, FEMA developed the standardized Hazards U.S., or HAZUS model to estimate losses caused by earthquakes and identify areas that face the highest risk and potential for loss. HAZUS was later expanded into a multi‐hazard methodology, HAZUS‐MH, with new models for estimating potential losses from wind (hurricanes) and flood (riverine and coastal) hazards. HAZUS‐MH is a Geographic Information System (GIS) based software program used to support risk assessments, mitigation planning, and emergency planning and response. It provides a wide range of inventory data, such as demographics, building stock, critical facility, transportation and utility lifeline, and multiple models to estimate potential losses from natural disasters. The program maps and displays hazard data and the results of damage and economic loss estimates for building and infrastructure. However, due to the limitations of the software (only estimates losses for earthquakes, hurricanes, and floods), Hennepin County did not use this software in 2018 or this new update in 2024. To estimate losses, Hennepin County Emergency Management used the Hennepin County Critical Infrastructure and Facilities Critical Facility Index (CFI) Priority Ranking Aid. This CFI was provided to municipalities, Hennepin County Departments, and special jurisdictions to assist in identifying critical infrastructure and facilities in their 182 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 6 community and estimate the potential losses. This CFI considers all hazards that were identified in the Risk Assessment. 1.1.3. Justification of Hazard Inclusion TABLE 1.3A provides the types of natural hazards that have been identified through analysis and assessment. TABLE 1.3A. Natural Hazards B1a Natural Hazards Types Justification for Inclusion Geological Landslide Countywide vulnerable area, especially where steep slopes are located, and heavy saturation occurs. Sink Hole History of occurrences, poses danger to population and property Soil Frost History of occurrences that have caused infrastructure damage Volcanic Ash Historic volcanic eruptions (western states) have spread ash into Hennepin County. Future occurrences may also impact the county Meteorological Climate Change There has been climate research done at the international level through the Intergovernmental Panel on Climate Change (IPCC) and local through the Minnesota State Climatology Office. Tornado Hennepin County has a strong history of tornadoes dating back to 1820. This hazard is a consistent threat to both life safety and property Winds, Extreme Straight‐Line Hennepin County has a strong history of derecho’s dating back to 1904. The Storm Prediction Center (SPC) also highlights Minnesota as being highly impacted by derecho activity during the summer months. Hail Hailstorms occur during severe convective storms and are an annual occurrence in Hennepin County. Very large hail has been recorded back as far as the National Weather Service has compiled data (1950). These storms pose a significant threat to people and infrastructure. Lightning Lightning is a regular occurrence and is associated with thunderstorm activity. Hennepin County has a history of lightning deaths as well as damage to property and infrastructure Rainfall, Extreme Hennepin County has had a history of extreme rainfall events, and the occurrences are becoming much more frequent. The State Climatology Office has published sixteen‐year research 183 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 7 documents on Minnesota flash floods caused by extreme rainfall. Heat, Extreme Extreme heat is an annual occurrence in Hennepin County and there have been several historic heat waves that have caused both deaths and injuries to our residents. Drought Several historic droughts have occurred across Hennepin County dating back to 1863. These events cause severe impacts on agriculture and the economy as well as increasing wildfire potential. Dust Storm Hennepin County has a history of dust storms going back to the 1930’s. These days’ dust storms are the cascading events of extreme drought. Cold, Extreme Extreme cold temperatures are an annual occurrence in Hennepin County, with historic outbreaks dating back to the 1800’s. These events pose significant threat to people and infrastructure. Winter Storm, Blizzard/Extreme Snowfall Hennepin County has a history of winter weather dating back to the late 1800’s. Varying degrees of severity occur in Hennepin County due to the different topography, with the worst conditions occurring in western Hennepin County. Winds, Non‐Convective High Although rare, extreme wind‐producing non‐ convective event may affect well over 100,000 square miles with wind damage, and may produce extreme impacts over tens of thousands of square miles Ice Storm Several ice storms have occurred in Hennepin County dating back to the 1930’s. These storms have caused great impact to infrastructure and people. The cascading effect of power outages is another threat that has occurred with past ice storms. Hydrologic Flooding, River Several historic flood events have occurred due to the Mississippi, Crow, and Minnesota River in Hennepin County. Flooding, Urban Urban flooding is a consistent problem in Hennepin County, due to torrential rainfall associated with thunderstorm activity. 184 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 8 THIS PAGE WAS INTENTIONALLY LEFT BLANK 185 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 9 SECTION 2 DISASTER DECLARATION HISTORY AND RECENT TRENDS 2.1. Disaster Declaration History One method to identify hazards based upon past occurrence is to look at what events triggered federal and/or state Disaster Declarations in Hennepin County. Disaster Declarations are granted when the severity and magnitude of the events impact surpass the ability of the local government to respond and recover. Disaster assistance is supplemental and sequential. When the local government’s capacity has been surpassed, a state disaster declaration may be issued, allowing for the provision of state assistance. If the disaster is severe enough that both the local and state government’s capacity is exceeded, a Federal Declaration may be issued, allowing for the provision of Federal disaster assistance. It is important to note that the Federal government may issue a Disaster Declaration through the U.S. Department of Agriculture (USDA) and/or the Small Business Administration (SBA), as well as through FEMA. The quantity and types of damages are the determining factors. Listed below in TABLE 2.1A are the previous Disaster Declarations that are of concern to Hennepin County.

Climate Adaptation Climate includes patterns of temperature, precipitation, humidity, wind, and seasons. Climate plays a fundamental role in shaping natural ecosystems and the human economies and cultures that depend on the. Climate adaptation refers to the ability of a system to adjust to climate change to moderate potential damage, to take advantage of opportunities, or to cope with the consequences. The International Panel on Climate Change (IPCC) defines adaptation as the “adjustment in natural or human systems to a new or changing environment”. Adaptation to climate change refers to adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities. 3.1.2. Hennepin West Mesonet (HWM) In order to adapt to climate change, Hennepin County has built the Hennepin West Mesonet, a network of remote sensors which provide highly accurate, near real‐time measurements of weather, soil and water conditions. Recent experiences across the Twin Cities metro area reveal a long‐standing vulnerability to dangerous weather or human‐caused conditions that form very quickly without clear advance indications. Fatal tornadoes in Rogers, MN (2006) and in North Minneapolis, MN (2011) both point to a need for more complete and rapid surface observations from a network of sensors spread across the area. A fatal landslide in Saint Paul, MN (2013) also shows that near real time soil temperature and saturation data across the metro could be useful in providing alerts for evolving dangerous conditions. Other vulnerabilities exist in our area to rapid‐onset flash flooding, straight‐line winds or hazardous materials releases which require many sensors with quick detection capability to provide useful public warning or evacuation decision‐making. The Hennepin West Mesonet delivers normal at different temporal resolutions, thus providing more precise climate monitoring. Through climate monitoring, the HWM provides an essential service and benefit of observing and precisely detecting impacts on the environment and ecosystems both at the geospatial and temporal scale in Hennepin County. Archived data and current observations provide consistent and high‐quality information from decision‐makers and researchers, information that can be utilized for development of research and prediction models, improving understanding of climate variability, advancing public climate education, and supporting development of mitigation and/or adaptation measures for local communities. 188 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 12 THIS PAGE WAS INTENTIONALLY LEFT BLANK 189 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 13 SECTION 4 COMPREHENSIVE NATURAL HAZARD ASSESSMENTS NATURAL HAZARD PROFILES 4.1. Geological Hazards 4.1.1. Hazard Assessment: LANDSLIDES 4.1.1.1. Definition. A landslide is the downward movement of rock, soil, or other debris along a slope. Other terms used for landslides are debris flow, earth flow, mudslide, slump, slope failure, mass wasting, and rock fall. The rate of landslide movement ranges from sudden to very slow and may involve small amounts of material up to very large amounts. The kinds of movement include falling, sliding, and flowing. Material can move as an intact mass or become significantly deformed and unconsolidated. The slopes that have landslides can range from near vertical to gently rolling with slopes above 30% having the highest susceptibility. 4.1.1.2. Range of magnitude Further work is needed among the Hennepin County landslide assessment team to develop range of magnitude. 4.1.1.3. Spectrum of Consequences B2b 4.1.1.3.1. PRIMARY CONSEQUENCES: 4.1.1.3.1.1. Transportation: Mobility is frequently stopped or slowed by landslides. When at the foot of slopes, roads and highways can be impacted by fallen rock, soil flows and landslide debris. When routes are at the crest of slopes, surfaces may be undercut by slides and fall away leaving voids and gaps in the road. Railroads are similarly impacted by landslides. The practice of cut and fill in road and rail grade construction can increase susceptibility to this problem. Besides direct damage to surface transportation routes, secondary impacts can occur if vehicles carrying hazardous materials rupture if struck by slides. 4.1.1.3.1.2. Electric utilities: Electric service lines often follow alongside roads, including their routes through valleys and ravines or along the crests of slopes. This makes them vulnerable to disruption from landslides. Cut power lines are a frequent feature of landslide activity. Landsides impact both lines suspended from utility poles and buried power lines. 4.1.1.3.1.3. Water, sanitary and storm sewer services: Cracked, broken or leaking water or sewer lines often have a significant role in triggering landslides in susceptible areas. 190 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 14 Inspections and maintenance of lines in vulnerable locations should be a priority to reduce risk. Water and sewer lines are also vulnerable to damage and destruction by landslide events. 4.1.1.3.1.4. Energy pipelines: Gas lines and other energy pipelines that pass‐through landslide susceptible areas may become weakened or severed by slide action. Damages may be caused by direct physical impacts or by indirect transmission of stresses through soil to the pipeline causing weaknesses or deformation of the lines. 4.1.1.3.1.5. Telecommunications: Telecommunications cables that pass‐through landslide susceptible areas may become weakened or severed by slide action. Damages may be caused by direct physical impacts or by indirect transmission of stresses through soil to the cable causing weaknesses or deformation of the lines. Fiber optic lines are particularly susceptible to deformation which can cause erratic signals or total signal loss. 4.1.1.3.1.6. Structural damage: Landslides impacts to structures ranges from rapid catastrophic destruction resulting from a landslide impact to gradual degradation of structures from slow earth movements. Complex load factors act on structures that are subject to landslide forces. Engineering assessment of compromised structures is vital to both response and recovery phases of a landslide incident. Landslide impacts to structures is both a life‐safety hazard and can also be an occasion for costly property damage. 4.1.1.3.1.7. Recreational impacts: Parks and trails are frequently placed in areas subject to landslides. Often parks or trails are in scenic areas in ravines or valleys associated with rivers with natural slopes being a main feature. They may also be part of former railroad rights‐of‐way that have been abandoned. Human‐modified slopes or other historic disruptions of natural soils and terrain can elevate landslide susceptibility in parklands. Slides in parks and trails is a risk to lives and safety, as well as a costly disruption to recreation activities. 4.1.1.3.2. SECONDARY CONSEQUENCES: 4.1.1.3.2.1. Hazardous material spill or release: If cut by a landslide, pipelines may release hazardous liquids or gasses, or polluting materials that can threaten lives, impact property or harm the environment as a secondary hazard after the landslide. 4.1.1.3.2.2. Fire or explosion: In certain instances, landslides may trigger fires or explosions at the site of buildings or other impacted structures, or where pipelines or service lines carrying gas or other flammable material. 4.1.1.4. Potential for Cascading Effects 4.1.1.4.1. Life‐Safety: Landslides can result in deaths and have done so in Hennepin County (1955) and adjacent metro counties (2013). Injuries have resulted in numerous other instances, as well as close calls. The landslide at Fairview‐Riverside hospital in Minneapolis (2014) narrowly missed pushing passing motorists on West River Road into the Mississippi River, for instance. 191 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 15 4.1.1.4.2. Infrastructure Destruction: Landslides can impact many kinds of critical infrastructure. Linear infrastructure such as roads, highways, railroads, pipelines, electric power lines and telecommunications cables are particularly vulnerable to slides that cross their paths. Water and wastewater infrastructure is not only vulnerable to slides as a linear system but may also help trigger landslide activity if a break occurs in water, sewer or storm sewer lines at sites that have other susceptibility factors. Point infrastructure located at susceptible sites anywhere between the crest to the foot of slopes are also vulnerable. 4.1.1.4.3. Property Damage: Homes and businesses have been damaged or destroyed by landslides in Hennepin County and surrounding counties. Lack of detailed landslide investigations and awareness in some cases have led to development on susceptible terrain. The fact that landslides are not covered by insurance policies has led to often catastrophic financial losses for homeowners and businesses that are hit. Expensive litigation has also often resulted from these incidents between property owners and cities. 4.1.1.5. Geographic Scope of Hazard B1c Landslide activity depends on certain localized factors (see above critical values) that result in an uneven distribution of landslides across Hennepin County. In general, Hennepin County landslide activity occurs in the valley walls of the Minnesota, Mississippi and Crow Rivers and their tributaries. Some of the exposed glacial sediments and bedrock layers in these valleys are unstable and subject to precipitation or spring‐ induced landslides. In the interior of Hennepin County, small landslides happen in steep slopes in glacial sediments that are found along streams, ravines, lakeshores, and wetlands. Artificially steepened slopes, often with disrupted soils and fills, also have been sites for landslides in Hennepin County. A Hennepin County Landslide Hazard Atlas is in development and is set for release in late 2018. 4.1.1.6. Chronologic Patterns Further work is needed among the Hennepin County landslide assessment team to develop Chronological Patterns 4.1.1.7. Historical Data B1d 4.1.1.7.1. HISTORICAL RECORD: Hennepin County Emergency Management commissioned an assessment of historic landslide activity in the county using archival data and historic news accounts. There are around two dozen landslides in Hennepin County that were documented in written accounts including a known location and date. June 19, 2014 (DR‐4182) June 1, 2014 April 2014 May 22, 2013 4.1.1.7.2. PRE‐HISTORIC EVIDENCE: Hennepin County Emergency Management commissioned an assessment of pre‐historic landslide activity in the county using LiDAR (Light Detection and Ranging) imagery. There are over one thousand sites in Hennepin County with landslide evidence that have been discovered through imagery analysis. 192 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 16 4.1.1.8. Future Trends B1e 4.1.1.8.1. TRENDS AND PROJECTIONS: The most significant trigger for landslide activity in Hennepin County is precipitation. Documented trends in precipitation in Minnesota, as well as projections into the future show an increase in overall rainfall, plus an increase in intense precipitation events. Recent landslide activity in Minnesota and Hennepin County has risen. It appears likely that landslide activity will continue to grow in tandem with precipitation trends. 4.1.1.8.2. EVENT PROBABILITIES: More analysis of the recently developed data is needed to determine landslide event probabilities in Hennepin County. 4.1.1.9. Indications and Forecasting Further work is needed among the Hennepin County landslide assessment team to develop modeling and forecasting methods. 4.1.1.10. Detection & Warning Additional work is needed among the Hennepin County landslide assessment team to develop detection and warning criteria. Indications of changes in key factors will be accomplished in large part by the Hennepin‐West Mesonet network of environmental sensors. 4.1.1.11. Critical Values and Thresholds 4.1.1.11.1. Slope. Also called the angle of repose, slope is a critical factor for landslide susceptibility. In Hennepin County, landslide activity starts to increase above 20% slope, and is most numerous on slopes between 30‐40%. Slopes may be either natural or artificially created by human activities. 4.1.1.11.2. Soil type: Soil type is important to landslide susceptibility for several reasons. Differences in the porosity and permeability of soils is important since it describes the degree to which soil types will either slowly retain or quickly shed water. Other characteristics such as soil structure may contribute to slope failure. Many soils in Hennepin have been disrupted or altered in some way by human activities. 4.1.1.11.3. Soil moisture: Soil moisture is a critical factor in Hennepin County landslides. Among other things, when water replaces air within soil pores, the overall weight of the soil increases. Increasing the weight of near surface soils can increase the likelihood of the material moving downslope and forming a landslide. The Hennepin County landslide assessment is developing specific soil moisture criteria for alert purposes. 4.1.1.11.4. Precipitation. Precipitation is one of the most critical factors in triggering landslides in Hennepin County. Duration, intensity, and recurrence of precipitation are important elements in precipitation‐initiated landslide events. The Hennepin County landslide assessment is developing specific precipitation thresholds for alert purposes. 4.1.1.11.5. Springs. Springs discharge water along slopes, increasing erosion and helping to trigger landslides. Springs in Hennepin have been mapped in detail. 193 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 17 4.1.1.11.6. Bedrock. The depth from the surface to bedrock is an important factor in some kinds of slides. Exposed bedrock is required for rock falls for instance. A shallow depth to bedrock may also facilitate flows and other forms of slides as well. 4.1.1.11.7. Surface conditions: Vegetation on slopes usually assists in stabilizing them against failure. Plants with deep root systems, often native species, are recommended to help slow slope erosion. Conversely, removal of vegetation that results in bare and exposed soil increases the risk of landslides and mudslides. 4.1.1.11.8. Soil temperature: The action of winter and spring freeze‐thaw cycles seems to help trigger some rock falls or topples. Thus, these types of landslides are the only ones that appear to happen outside of the normal rainfall/thunderstorm season of Hennepin County. The freeze‐ thaw cycles allow water, trapped in voids and crevices in rock, to expand and push rock apart, sometimes triggering a fall. 4.1.1.12. Prevention Further work is needed among the Hennepin County landslide assessment team to develop prevention methods. 4.1.1.13. Mitigation 4.1.1.13.1. Avoidance (Prevention). The most effective mitigation measure against landslide fatalities, injuries, infrastructure disruption and property loss are avoiding development and certain human activities at sites prone to landslides. This is a preventive action. Avoidance may be accomplished through evidence‐based zoning policies that utilize local area landslide hazard assessments that trigger site‐specific landslide investigations when appropriate if development or other uses are proposed at sites inside identified hazard zones. Specific actions include avoiding cutting into slope sides or at the food of slopes, and not placing excessive weight on the top of slopes by erecting structures there. 4.1.1.13.2. Education and public alerts. Education of zoning officials, landowners and need accurate local information in order to make sound decision regarding their development and activities in landslide susceptible terrain. A simple knowledge of landslide risk also sets the foundation for appropriate action when a public alert is issued. Public alert thresholds, messages and distribution methods must be developed. 4.1.1.13.3. Active mitigation methods. Geometric methods include changes in slope angle to reduce the chances of landslides. Hydrological methods consider surface, shallow and deep‐ water drainage and attempt to improve the ability of landslide‐susceptible sites to drain water effectively. Finally, mechanical methods include the use of rock anchors, netting, retaining walls, or pilings. In general, these methods are expensive and are suitable only of sites of limited size in areas where development is of high importance. 4.1.1.14. Response Further work is needed among the Hennepin County landslide assessment team to develop Response 194 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 18 methods. 4.1.1.15. Recovery Further work is needed among the Hennepin County landslide assessment team to develop Recovery methods. 4.1.1.16. References 195 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 19 4.1.2. Hazard Assessment: SINKHOLE 4.1.2.1. Definition. A sinkhole is a bowl‐shaped depression in the land surface. Sinkholes are also called subsidence, which is a downward settling of the surface without any horizontal movement. Sinkholes result from natural processes where near‐surface carbonate bedrock is dissolved by water to form underground spaces, also called voids. These voids typically form along existing joints or cracks in the rock that aid the movement of water. Some voids grow toward the surface where infiltrating surface waters meet and flow downward into the drain of the void. This action weakens the rock. Eventually, the weight of overlying materials can result in a collapse. Areas favorable for sinkhole development are called karst terrain. Certain human activities may speed up the natural sinkhole processes in karst areas. Human activities outside of normal karst terrain can also trigger unexpected human‐caused ground collapses in materials not usually prone to sinkholes. 4.1.2.2. Range of magnitude Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored sinkhole hazard assessment in 2020. 4.1.2.3. Spectrum of Consequences B2b 4.1.2.3.1. PRIMARY CONSEQUENCES: Sinkholes and other land subsidence can cause significant direct damage to buildings, roads, water supply systems and other infrastructure. The loss of land usable for farming or other development is another consequence of sinkhole activity. Finally, groundwater contamination is a significant consequence of karst and sinkhole activity. Subsurface water flow in karst areas creates a situation where surface water, along with their contaminants, quickly travel deep into aquifers without significant filtration. The problem is worsened when people use sinkholes as garbage dumps, which was formerly a common practice in the United States. 4.1.2.3.2. SECONDARY CONSEQUENCES: 4.1.2.3.2.1. Disease. Dumping of wastes into sinkholes maybe a source of disease. A disease outbreak in Harmony, Minnesota (Fillmore County) was traced to a sinkhole used as a disposal point for human waste. 4.1.2.3.2.2. Dam failures. There have been instances of dams and other water‐control infrastructure being undermined by sinkholes and other karst activity. 4.1.2.3.2.3. Fires or explosions. When structures, or infrastructure such as pipelines are impacted by sinkholes and gas lines are compromised, fires and explosions are possible. 196 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 20 4.1.2.4. Potential for Cascading Effects In Minnesota, most sinkholes are in rural areas and develop very slowly. These sinkholes are not dangerous, and they do not cause much destruction except for the loss of crop land. When sinkholes happen in developed urban areas however, they have the potential to be much more costly and, in some cases, even dangerous. The active karst areas in southeast Hennepin County are in places with concentrated developments of housing, businesses, schools and infrastructure. The potential for destructive sinkhole events in Hennepin County has not been adequately assessed. Hennepin County Emergency Management is initiating a study of sinkhole hazards in the county that is expected to be complete by 2020. 4.1.2.5. Geographic Scope of Hazard B1c The southeastern three‐quarters of Hennepin County is underlain by carbonate bedrock and is karst terrain. The western and northern limits of this area begin in the south around Excelsior and extend northward into Medina, then eastward into Brooklyn Center. Most of this area is comprised of covered karst which has overlying glacial material more than 100 feet in depth. An area with pockets of transitional karst which has overlying glacial material between 50 and 100 feet thick is roughly bounded in the south by Edina, west to Wayzata, and northeast to Brooklyn Center. Active karst is found in mostly along the Mississippi River from North Minneapolis south to Fort Snelling. Scattered outlying pockets of active karst can be found westward from Golden Valley south to St. Louis Park. Active karst areas have less than 50 feet of overlying material covering them. Note: Other types of land subsidence are directly caused by human activities and are dealt with in the human‐caused, industrial/technological section of this hazard assessment. These include water or sewer system breaks that cause sinkholes or collapse of underground tunnels. 4.1.2.6. Chronologic Patterns Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored sinkhole hazard assessment in 2020. 4.1.2.7. Historical Data B1d The Seven Oaks Park in south Minneapolis is a sinkhole. The surface depression is approximately 300 feet wide and over 20 feet deep. The time of formation of the sinkhole is unknown but predates the construction of the structures around it. Seven Oaks Park is located between E 34th Street and E 35th Street at 47th Avenue South in Minneapolis (USNG 15T VK 83754 76384). Other possible sinkholes are nearby but await more definitive confirmation. There have been no other naturally caused incidents that are within the scope of this plan. 4.1.2.8. Future Trends B1e Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored sinkhole hazard assessment. 4.1.2.9. Indications and Forecasting 197 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 21 Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored sinkhole hazard assessment in 2020. 4.1.2.10. Detection & Warning Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored sinkhole hazard assessment. 4.1.2.11. Critical Values and Thresholds 4.1.2.11.1. Bedrock material: Areas susceptible to sinkholes (karst terrains) are underlain by water‐soluble, but relatively impermeable bedrock such as limestone (calcium carbonate). Soluble rocks dissolve when exposed to certain acids, including acidic water. Over time, acidic water flowing through joints and cracks will dissolve and remove large amounts of soluble rock creating many void spaces. In more unusual instances, sandstones or even quartzite may develop sinkholes. In these cases, the bedrock is more permeable, but less soluble. Slower sinkhole development may occur in these rocks. 4.1.2.11.2. Water acidity: Acidic surface water and groundwater is required for natural sinkhole formation as the agent that dissolves soluble bedrock. Pure water has a pH of 7.0, which is neutral – neither acidic nor base. However, water in nature is not pure. Instead, it contains natural impurities which make it acidic. Unpolluted rainwater has a pH of around 5.6 (acidic). Rainwater in Minnesota contains atmospheric pollutants which further lower the pH, increasing acidity. Once at the surface, water can become further acidified by exposure to nitrogen fertilizers or other chemicals. When this water infiltrates into the bedrock it begins to gradually dissolve any carbonate rocks. 4.1.2.11.3. Bedrock depth: For a void to cause a collapse of the overlying surface material it must be close to the surface. Active karst areas have carbonate bedrock less than 50 feet below the surface. Transitional karst areas have carbonate bedrock covered by material between 50 and 100 feet. In some instances, sinkholes can occur in these conditions as well. Covered karst areas have more than 100 feet of overburden. Sinkholes are unlikely to develop in such deep conditions. 4.1.2.11.4. Bedrock topography. Once water penetrates the soil, it will arrive at the bedrock layer. Typically, the bedrock is much less permeable than the overlying unconsolidated soils which promotes lateral water flow. The water will flow according to the topography of the bedrock finding crevices and valleys that collect water until a penetration point can be found into the bedrock. 4.1.2.11.5. Joints, fractures, and bedding planes: These features provide easy routes for water to travel through the rock. As water moves through this network of joints, fractures and bedding planes, chemical action of the acidic water dissolves the bedrock. Joints and fractures are often oriented in parallel and perpendicular patterns. Because of this, voids and sinkholes also are often aligned to follow these patterns. 4.1.2.11.6. Water table: Fluctuations in ground water levels can affect sinkhole activity. Abrupt 198 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 22 changes in ground water level can induce sinkholes. Ground water drawdown often increases sinkhole activity. 4.1.2.11.7. Construction and development. Human development activities that add extra weight and pressure to land surfaces by construction of new buildings and other infrastructure may accelerate sinkhole formation. The alteration of surface and subsurface drainage flows due to human development may also accelerate sinkhole formation by increasing the flow of water through sinkhole drains. Water and sewer lines in karst areas are susceptible to damage from sinkholes and other land subsidence. When water or sewer lines leak or break, the released water may enter sinkhole systems and quickly enlarge voids, accelerating sinkhole formation. 4.1.2.12. Prevention 4.1.2.12.1. Avoidance The most effective prevention/mitigation measure against sinkhole fatalities, injuries, infrastructure disruption and property loss are avoiding development and certain human activities at sites prone to sinkholes. This is a preventive action. Avoidance may be accomplished through evidence‐based zoning policies that utilize local area sinkhole hazard assessments that trigger site‐specific sinkhole risk investigations when appropriate if development or other uses are proposed at sites inside identified hazard areas. Zoning‐based measures would be challenging in Hennepin County because much of the karst areas have already been developed. 4.1.2.13. Mitigation 4.1.2.13.1. Education. Education of zoning officials, landowners need accurate local information to make sound decision regarding their development and activities in sinkhole susceptible terrain. These require detailed sinkhole hazard maps. HCEM completed its Landslide Hazard Atlas to assist in mitigation, avoidance, and planning response efforts. The atlas was release by 2020. 4.1.2.14. Response With the completion of the Landslide Hazard Atlas in 2020. Response effort follows five key principles: engage partnerships, have a tiered response, have a scalable, flexible, and adaptable operational capability, unify your effort, and be ready to act. Scene stabilization will be achieved when the immediate threat to life‐safety and property damage at the scene have been stopped. 4.1.2.15. Recovery The recovery process begins soon after the incident happens. The objective is to bring households and communities back to normal activities post‐disaster. Relief can come from a variety of ways. Public Assistance, Individual Assistance, Emergency Repair, or Permanent Repair. 4.1.2.16. References Hennepin County landslide Hazard Atlas.

Hazard Assessment: SOIL FROST 4.1.3.1. Definition. Soil frost is caused when water, which is present as a component of soil, freezes into pore ice. The depth to which this freezing penetrates is called the deep frost. Some soils are vulnerable to frost heaving, which is the vertical displacement of the surface due to frost expansion or the development of ice lenses. Melt collapse happens when the ice lenses melt. These effects can damage roads and building foundations and other infrastructure. Deep penetration of frost can also have a devastating impact on critical buried infrastructure, such as water and wastewater pipes. In extreme cases, fire hydrants and fire sprinkler water supplies may freeze. Hard impervious frost layers in the soil also can worsen springtime rain and snowmelt flooding by not allowing water to penetrate the soil and increasing run‐off. 4.1.3.2. Range of magnitude Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored soil frost hazard assessment in 2020. 4.1.3.3. Spectrum of Consequences B2b 4.1.3.3.1. PRIMARY CONSEQUENCES 4.1.3.3.1.1. Water utilities: In Hennepin County, water service lines are typically buried between 78 to 90 inches (198.1 to 228.6 centimeters) deep. This depth is usually protecting these lines against freezing. When particularly deep frost is formed, however, water service lines may freeze, cutting off water services to residences, businesses, and government facilities. Bottled water delivery is often the response of choice while awaiting water service restoration. Water service freezing not only stops the flow of potable water to an address, it may also interrupt fire protection systems such as sprinklers or standpipes. Water mains, which are buried deeper than service lines, are less likely to freeze. If they freeze, then fire hydrant services also are interrupted. Thawing frozen water lines is difficult and time consuming. It requires special equipment and experience. Some methods may cause structural fires. In widespread instances of frozen water lines, service may be cut for days to weeks. Without intervention, frozen water service lines in Hennepin County would thaw by May. Service line freezing may be prevented by keeping a pencil‐sized flow of cold tap‐water always moving through the system. Prevention is usually done at the request of the local water utility. 4.1.3.3.1.2. Wastewater services: In general, municipal sewer lines have similar depth requirements as water service lines to prevent frost damage or disruption. Sewer lines typically have fewer freeze problems during deep frost events than water lines, however. Rather than frost causing problems for municipal sewer systems, a bigger issue seems to be impacts to household septic systems. 200 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 24 4.1.3.3.1.3. Energy pipelines: Gas and other pipelines are vulnerable to the effects of frost. According to data from the Pipeline and Hazardous Materials Safety Administration (PHMSA), 82% of cold weather failures of distribution pipelines in the US (1984 through 2014) were caused by frost heave. 4.1.3.3.1.4. Communications: Buried fiber optic cables are susceptible to impacts from frost. This occurs when water that has infiltrated the fiber optic conduit freezes. The most vulnerable areas where sites were cables were shallow or exposed near bridges. While freezing has no impact on copper cables, fiber optic cables may be bent by the expansion of the ice. Various levels of signal degradation may occur, including complete failure. As a countermeasure, some communication companies have injected their conduit with anti‐freeze compounds. 4.1.3.3.1.5. Structural damage: Frost heave of soils can cause significant damage to structures including cracked foundations or slabs and other effects from ground movement. 4.1.3.3.1.6. Transportation: Roads and highways are impacted frost action. Differential frost heaves are creating blisters in pavement that leads to cracking and potholes. Frost can block proper drainage and lead to additional problems. Road load‐bearing capacity is affected by freeze‐thaw cycles. 4.1.3.3.2. SECONDARY CONSEQUENCES: Frost induced breaks in gas or oil pipelines can cause fires or explosions. 4.1.3.4. Potential for Cascading Effects 4.1.3.4.1. Specific sites. Deep frost can impact buried infrastructure that carry water, wastewater, energy or communications causing service interruption by freezing or by physical damage. Frost heaving can also cause damage to buildings and other structures. These damages are highly dependent on localized conditions leading to impacts that area variable from address to address. Frost depth impacts may be widespread but spotty. 4.1.3.4.2. General areas. Deep frost can create a frozen and temporarily impervious layer of soil across wide regions which limits infiltration of snow‐melt water and rainwater in springtime. This additional runoff worsens springtime flooding across river basins and stream watersheds. 4.1.3.5. Geographic Scope of Hazard B1c All areas of Hennepin County and the State of Minnesota are vulnerable to soil frost during winter months. Minnesota and the adjacent state of North Dakota are the center of deep frost activity in the 48 contiguous United States. While frozen soils are routine in all parts of Minnesota, problems occur when frost penetrates deeper than normal. The Minnesota State Building Code (MSBC) Rule 1303.1600 places construction frost depth in Hennepin County at 42 inches (106.7 centimeters). 201 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 25 4.1.3.6. Chronologic Patterns Unknown, pending conclusion of the Hennepin County Emergency Management‐sponsored soil frost hazard assessment in 2020. 4.1.3.7. Historical Data B1d 4.1.3.7.1. Comprehensive. Hennepin County Emergency Management (HCEM) has not yet systematically investigated historical records of local frost depth. Precise frost measurements using frost tubes or other sensors are unlikely to have been conducted anywhere in Hennepin County prior to the HCEM program which started in 2015. The nearest historic soil frost records are probably measurements taken at the University of Minnesota, Saint Paul campus. These St. Paul records are for frost under sod. It is possible that written historical accounts of frost depth and their effects might be found in records of municipal utility providers. These records, if discovered, would probably be for frost under pavement which impacted water lines and other utilities. 4.1.3.7.2. Winter of 2013‐2014. The coldest Hennepin County winter since 1978‐1979 occurred in 2013‐2014 with a sustained three‐month cold snap. The mean temperature for the months of December, January and February was 9.8F degrees at MSP airport. The normal for this time period is 18.7F degrees. More snow fell than average during the period as well (57.2 inches three‐month total). Most of it fell late in the period. Frost was pushed much deeper than average. Anecdotal reports by public work crews working on frozen water service lines reported frost as deep as 7 to 8 feet in Plymouth. Twelve cities, not including Minneapolis, provided information regarding service interruptions. In these cities were a total of 324 water freeze up incidents, mostly service lines. In addition, 1 hydrant froze, 2 water mains, and 4 sewer lines also became frozen. The longest outages were over one week. Residences, businesses, care facilities, and government buildings were impacted. In several instances, cities had to distribute bottled water to affected residences. There have been no other naturally caused incidents that are within the scope of this plan. 4.1.3.7.3. Pre‐Historic Evidence: Unknown. HCEM has not found any research regarding pre‐historic frost depth in Hennepin County. 4.1.3.8. Future Trends B1e Undetermined. Climate change is having a significant impact on Minnesota and Hennepin County. Forces generated by climate change are sometimes at odds over the net effect experienced in this area during any winter. For instance, there has been an overall warming trend in Minnesota winters, including a shorter winter season and higher average temperatures. More recently, prolonged outbreaks of extreme cold air have impacted Minnesota and Hennepin County. These include the winter of 2013‐2014 and the winters of 2016‐2017 and 2017‐2018. These cold outbreaks appear to be related to warming in the Arctic that has weakened the Polar Jet Stream. The weakened jet stream is less able to contain cold Arctic air in high latitudes and block it from streaming south. Some scientists theorize that prolonged outbreaks of extreme cold polar air may be a recurring feature of future winters in Minnesota. When coupled with low or no‐snow cover conditions, outbreaks of extreme cold may push frost deeper into the soil. 202 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 26 EVENT PROBABILITIES: Unknown. Further research is needed to determine trends and probabilities of future deep soil frost events in Hennepin County. 4.1.3.9. Indications and Forecasting Additional study is needed to develop deep soil frost event models and forecasts for Hennepin County. Adequate weather forecasting already exists and would certainly be a major factor in any future soil frost forecasts. Better data on the behavior of frost in local soils under various temperature, surface material, soil moisture and snow cover conditions is required to develop models and forecasts. Hennepin‐West Mesonet data will provide much of the needed information. 4.1.3.10. Detection & Warning In 2015, following the disruptive winter of 2013‐2014 when hundreds of water service lines were frozen, Hennepin County Emergency Management (HCEM) began to install a network of manually read frost tubes at locations around Hennepin County. When possible, two frost tubes were installed at the same site. One tube was for measuring frost depth under sod, and the other for frost depth under pavement because of the significant differences between the two. Frost tubes are usually located near a Hennepin‐West Mesonet sensor station so that weather factors can be compared to the frost depth at the site. The measurements, taken at least weekly, can provide indications that the frost is pushing deeper than normal and is beginning to threaten water and sewer services, fire protection capabilities, and other vital services. When appropriate, HCEM will send out alerts to public works officials that frost may threaten their water and sewer infrastructure. 4.1.3.11. Critical Values and Thresholds 4.1.3.11.1. Air temperature: Air temperatures below freezing (32F/0C) are required to initiate soil frost formation. A freezing index based on degree‐days of freezing may be used to roughly estimate frost depth potential in an area. 4.1.3.11.2. Pavement. Human‐made surfaces, such as concrete or asphalt roadways create ideal conditions for exceptionally deep frost penetration into soil. The differences between frost depth under paved roads and frost depth under natural sod is large enough to produce a few feet of difference at the same site. Therefore, measurements should specify of they are taken under pavement or under sod. Factors such as the thermal conductivity of pavement and the removal of snow cover combine to push frost deep into the underlying soils. This is important because a lot of buried infrastructure is underneath immediately adjacent to roadways, increasing their vulnerability to frost. 4.1.3.11.3. Surface albedo: Surface albedo is the ratio of irradiance of solar energy reflected to the irradiance of solar energy absorbed by a surface. Asphalt, dark soils, turf grasses and forests have low albedo. Snow cover, sand, and winter prairie grasses have higher albedo. The albedo of the primary surface is important because it influences the snow cover characteristics of the site. Snow cover is a central factor is controlling frost depth. 4.1.3.11.4. Soil type: Different soil types freeze at different rates. Frost tends to penetrate less in clay (heavy textured) soils and more deeply in silty or sandy (lighter textured) soils. Inorganic soils 203 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 27 with >3% by weight of grains finer than 0.02 millimeter in diameter (silts, silty sands, and clays) form frost lenses more easily and have a very high susceptibility to frost heaves. 4.1.3.11.5. Moisture content: Soil moisture effects the initial freezing of soil because of the increased heat capacity and thermal conductivity of the soil surface. The initial freezing point of soil is usually delayed with increasing amounts of soil moisture. As winter progresses, the soils that have started with greater amounts of water filling pore spaces experience greater overall frost depths due to increased thermal conductivity since air is a less efficient conductor of heat than water. Water tables within 10 feet of the surface are a contributing factor for frost heaves. 4.1.3.11.6. Snow cover: The insulating effect of snow cover is a key factor in slowing the penetration of frost into the soil. Each foot of undisturbed snow cover typically reduces the depth of soil freezing by an equal amount. Snow cover is a function of the amount of snowfall received at a location, along with the type of surface material at that location. Darker colored surfaces also tend to help accelerate snow melting and help remove the insulating effect of snow (see albedo). Snow removal on paved surfaces helps to push frost deeper by not allowing insulating snow cover to accumulate. 4.1.3.11.7. Vegetative cover: Like snow, vegetation acts as an insulator to slow frost penetration into the soil. Loose grasses or leaves can form insulating air pockets that reduce the depth that frost can penetrate. 4.1.3.11.8. Geographic location: In general, in Minnesota the average initial soil frost date is earlier with higher latitudes and more westerly longitudes. More northerly latitudes have longer overall frost seasons on average. In Minnesota the change in average freezing date is about 3.3 days per degree of latitude. 4.1.3.11.9. Infrastructure condition. In general, older buried infrastructure such as service lines, pipes and conduits are in a more deteriorated condition than newer infrastructure and are more susceptible to damage from deep frost. 4.1.3.12. Prevention Unknown, pending conclusion of the Hennepin County Emergency Management assessment in 2020. 4.1.3.13. Mitigation 4.1.3.13.1. Frozen water lines. Water lines can be protected against deep frost by ensuring they are buried to the correct depth. Lines which are already installed can resist freezing by ensuring a constant flow of a small amount of water (pencil‐diameter stream from a faucet) flowing in from the service line. Typically, water utilities will request that customers maintain running water at addresses that have had freezing problems in the past. 4.1.3.13.2. Buildings, roads, and infrastructure. When it occurs, typical vertical ground movement due to frost heaves and melt collapse is between 4 to 8 inches. Extreme movement can be up to 24 inches. These ground movements are enough to cause significant damage to human‐made structures. Various mitigation measures can protect structures against frost heave and melt collapse. Buildings which are heated rarely experience frost heave problems because of 204 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 28 a portion of the heat is received by the surrounding soil which prevents ice lens formation and heave action. For unheated structures, heaves can be prevented through keeping waters out of freezing zone. Another mitigation method is to ensure soils surrounding structures are those less susceptible to frost problems. 4.1.3.13.3. Distribution pipelines. Pipelines are susceptible to frost heave‐produced ground movements. Pipe materials, joining methods, soil conditions and water drainage are all important factors in prevention of damages. In areas susceptible to frost heave damage, pipeline materials should shift away from cast iron and threaded steel pipe and be replaced by plastic of welded steel. Other measures can be taken to reduce the chances of frost damage to pipelines. These include drainage to reduce water in the soil and eliminate standing water over pipelines. Soil conditions may also be modified to reduce susceptibility to ice lens formation. 4.1.3.13.4. Flooding. Deep frost penetration can worsen spring meltwater flooding by preventing soil absorption of snow melt or rainwater. Flood control and management measures must consider the potential for deep frost effects in spring flood scenarios. 4.1.3.14. Response Unknown, pending conclusion of the Hennepin County Emergency Management assessment in 2024. 4.1.3.15. Recovery Unknown, pending conclusion of the Hennepin County Emergency Management assessment in 2024. 205 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 29 4.1.4. Hazard Assessment: VOLCANIC ASH 4.1.4.1. Definition. Volcanic ash consists of tiny particles of jagged rock and natural glass blasted into the air by a volcano. This ash poses threats to human and animal health, aircraft engines, electronics, machinery, electrical power generation and telecommunications. Winds may carry ash thousands of miles, impacting areas and people far away from the volcano itself. Volcanic ash is not the product of combustion, and thus is not like the light ashes made by burning leaves, wood, or coal, for example. Volcanic ash particles are hard rock fragments that do not dissolve in water. Ash is extremely abrasive, mildly corrosive and can conduct electricity when wet. 4.1.4.2. Range of magnitude Unknown, pending conclusion of the Hennepin County Emergency Management assessment in 2020. 4.1.4.3. Spectrum of Consequences B2b 4.1.4.3.1. PRIMARY CONSEQUENCES 4.1.4.3.1.1. Aircraft. Aircraft in flight are particularly vulnerable to the effects of exposure to volcanic ash. Often the ash cloud is invisible to the flight crew, and must be detected by the odor of sulfur, or by a haze developing on the windscreen. The electrically charged ash particles can interfere with navigational and flight instruments, and communications equipment. The ash may clog the pitot‐static system that indicates airspeed and feeds air to several vital flight instruments. Abrasion by the jagged particles can erode leading edge surfaces, and quickly produce a haze on windscreens so that pilots are unable to see through them. Turbine compressor blades in jet engines can wear quickly. Finally, the low melting temperature of volcanic ash means that the particles liquefy in the ignition chamber of jet engines, but quickly cool in the next engine stage and end up coating engine parts with a glaze of volcanic glass. Engines have failed from ingesting volcanic ash. Repair costs from encounters with ash can cost millions of dollars per aircraft. 4.1.4.3.1.2. Surface transportation. At the surface, ash fall could produce hazardous driving conditions by cutting visibilities when at least 1 millimeter (1/32 inch) of ash accumulates on roadways. Ash fall amounts of accumulation greater than 1 mm (1/32 Inch) also obscure markings on roadways, causing confusion among drivers in the low visibility conditions. 4.1.4.3.1.3. Human health. The main health impact of volcanic ash to people (and animals) are to the respiratory tract and to the eyes. Ash particles less than 100 nanometers in size produce upper airway irritation. Ash particles less than 10 nanometers in size can penetrate deep into the lung and worsen the conditions of those 206 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 30 with various pre‐existing lung diseases. Ashes with high crystalline silica content may also increase risk for suture silicosis. Technical analysis is required to determine silica component of the ash. 4.1.4.3.2. SECONDARY CONSEQUENCES: Unknown at this distance from source volcanoes. 4.1.4.4. Potential for Cascading Effects Volcanic ash is capable of various degrees of destruction, largely based on the distance it has traveled from the volcano of origin. Ash falling to the surface in areas near the volcano is much coarser and heavier than the ash that winds can carry for hundreds of thousands of miles from the eruption. Since the principle volcanic ash producing threats are located at least 800 miles west of Hennepin County, the destructive potential is restricted to the characteristics of ash that can be wind‐transported that far. The most significant impacts at this distance involve the critical safety threat of aircraft flying through invisible high‐ altitude ash clouds. Sensitive electronic devices including computers, communications equipment, medical devices, and other critical equipment can be damaged by the abrasive and electrically charged particles. Finally, human and animal health impacts can occur because of the effect that the irritating volcanic ash has on the respiratory system and on eyes. 4.1.4.5. Geographic Scope of Hazard B1c Most volcanic ash is produced during explosive volcanic eruptions. Explosive volcanoes are found along the boundaries of Earth’s converging tectonic plates that are converging, such as along the Pacific Rim, sometimes called the Ring of Fire. Other volcanic activity is at mantle plumes, called ‘hot spots, which melt through tectonic plates. The closest volcano to Hennepin County is the Yellowstone Caldera, located about 800 miles west, in northwest Wyoming. The belt of volcanoes in the Cascade Range are about 1300 miles west of Hennepin County in eastern Washington State. Prevailing winds from the west set up Minnesota as a potential recipient of ash from volcanic eruptions in the western United States, Canada, and Alaska. 4.1.4.6. Chronologic Patterns Unknown, pending conclusion of the Hennepin County Emergency Management assessment in 2024. 4.1.4.7. Historical Data B1d Several major eruptions have occurred in North America where ash clouds traveled great distances. These include the Spurr Volcano, Alaska (27 June 1992); Mount Saint Helens, Washington (18 May 1980) and the Novarupta Volcano, Alaska (06 June 1912). Ash from the Spurr volcano traveled over Minnesota (see graphic at the beginning of this section) in September 1992. Pre‐Historic Evidence Some extremely large volcanic eruptions occurred in the geologically recent past in the Yellowstone Super‐Volcano complex in northwestern Wyoming. The United States Geological Survey estimates an average recurrence rate of explosive volcanic eruptions at Yellowstone to be between 600,000 and 800,000 years. The pervious explosive eruptions have been the Lava Creek Eruption, Yellowstone, WY (630,000 years ago); the Mesa Falls Eruption, Yellowstone, WY (1.3 million years ago); and the Huckleberry Ridge Eruption, Yellowstone, WY (2.1 million years ago). Massive ash falls were generated 207 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 31 by these eruptions. There have been no other naturally caused incidents that are within the scope of this plan. 4.1.4.8. Future Trends B1e There is no evidence that typical volcanic activity levels among the volcanoes that pose an ash fall threat to Hennepin County are either increasing or decreasing. These volcanic events happen in geologic time in which eruption recurrence rates of hundreds, thousands or even hundreds of thousands of years are possible. Event Probabilities: The United States Geological Survey (USGS) has estimated the activity level and eruption recurrence rate of each of the volcanoes in the western United States, Canada, and Alaska. 4.1.4.9. Indications and Forecasting Volcanic forecasting is the responsibility of the United States Geological Survey and its Volcano Observatories. USGS scientists categorize volcanoes and estimate their explosive potential based on evidence of past eruptions. 4.1.4.10. Detection & Warning USGS scientists monitor precursor activity and are often able to issue alerts of impending eruptions months or weeks prior to the event. Ash clouds are tracked by the National Oceanic and Atmospheric Administration. The Washington Volcano Ash Advisory Center (WVAAC) is responsible to provide alert and warning services for aviation safety. The Minneapolis Air Route Traffic Control Center (ARTCC) is served by the WVAAC. 4.1.4.11. Critical Values and Thresholds 4.1.4.11.1. Diameter: Ash particles are less than 2 millimeters in diameter down to very extremely small particles of less than 0.001 millimeter. Volcanic ash is lofted high into the atmosphere and can be blown thousands of miles away from the volcano. Larger and heavier particles will fall to Earth much more quickly than smaller and lighter particles which may remain aloft for weeks or longer. Extremely small particles suspended in the air can be invisible to the human eye, yet present hazards to aviation. 4.1.4.11.2. Density: Ash particles have variable degrees of density (pumice, 700‐1200 kg/m3; glass, 2350‐2450 kg/m3; crystals, 2700‐3300 kg/m3; and rock particles, 2600‐3200 kg/m3). The high‐density ash particles are hard (5 Mohs scale). Window glass and steel have a Mohs hardness of 5.5, for example. Ash particles have sharp edges making them very abrasive. 208 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 32 4.1.4.11.3. Weight: Fallen volcanic ash is heavy and poses a risk to buildings close to the eruption, particularly those with flat roofs. A dry layer of ash 4 inches thick weighs 120 to 200 pounds per square yard, and wet ash weight is usually double the dry totals. Ash weight should not be a threat to Minnesota structures. 4.1.4.11.4. Prevailing winds. Both east‐west zonal flow and Alberta Clipper systems bring winds to Minnesota from regions that host active volcanoes. 4.1.4.12. Prevention Unknown, pending conclusion of the Hennepin County Emergency Management assessment in 2024. 4.1.4.13. Mitigation 4.1.4.13.1. Avoidance. Avoidance of flight through ash clouds is vital to aviation safety. Ash cloud alerts and warnings provide air route control centers the information they need to vector aircraft away from ash clouds. 4.1.4.13.2. Personal protection. Personal protective equipment such as filtration masks and eye protection from covered goggles are needed to avoid some of the health risks posed by volcanic ash. 4.1.4.13.3. Barriers. Sealing off rooms that have sensitive electronics can be done with plastic sheets and duct tape. Covering individual devices may also help protect them against ash. 4.1.4.14. Response Unknown, pending conclusion of the Hennepin County Emergency Management assessment. 4.1.4.15. Recovery Unknown, pending conclusion of the Hennepin County Emergency Management assessment. 209 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 33 4.2. Hydrological Hazards 4.2.1. Hazard Assessment: FLOODING, URBAN 4.2.1.1. Definition Urban flooding occurs when rain overwhelms drainage systems and waterways and makes its way into the basements, backyards, and streets of homes, businesses, and other properties. As land is converted from fields or woodlands to roads or parking lots, it loses its ability to absorb rainfall. Because of this, densely populated areas are at a high risk for flash floods. The construction of buildings, highways, driveways, and parking lots increases runoff by reducing the amount of rain absorbed by the ground. 4.2.1.2. Range of magnitude The 10‐year average of recent flood damages is about $20 billion. However, some years have run as high as $40 billion. Deadliest Flash Flood (Dam Collapse): 1889, Johnstown Pennsylvania: 2,200 people died. Deadliest torrential rain flood: July 31, 1976, Big Thompson Canyon, Colorado: 143 people died Longest duration: 1993 61 days; The Great Midwest Flood Greatest USD Damage: $12 Billion 1993; The Great Midwest Flood 4.2.1.3. Spectrum of Consequences B2b There are several ways in which storm water can cause the flooding: overflow from rivers and streams, sewage pipe backup into buildings, seepage through building wall and floors, and the accumulation of storm water on property and in public rights‐of‐way. Sometimes, streams through cities and towns are routed underground into storm drains. During heavy rain, the storm drains can become overwhelmed and flood roads and buildings. Low spots, such as underpasses, underground parking garages, and basements can become dangerous. The economic, social, and environmental consequences of urban flooding can be considerable. Water quality issues can arise from sewer overflow’s debris contamination, fertilizer runoff from agriculture etc.… which affect public health with possible contaminated drinking water and water borne illnesses. The cost of removal of soil from landslides, or sediment deposits from flooding can be high, as well as wildlife habitat reconstruction as wildlife habitat can be ruined by wash out, water contaminates, oxygen loss, or loss of access to food sources. Chronically wet houses are linked to an increase in respiratory problems, and insurance rates and deductibles may rise to compensate for repeated basement flooding claims. Industry experts estimate that wet basements can lower property values by 10‐25 percent and are citied among the top reasons for not purchasing a home. According to FEMA, almost 40 percent of small businesses never reopen their doors following a flooding disaster. Between 2006–2010 the average commercial flood claim made to the NFIP amounted to just over $85,000. Urban flooding also erodes streams and riverbeds and degrades the 210 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 34 quality of our drinking water sources and the health of our aquatic ecosystems. 4.2.1.4. Potential for Cascading Effects Structures that encroach on the floodplain, such as bridges, can increase upstream urban flooding by narrowing the width of the channel which can cause sediment and debris carried by floodwaters further because the flow is occurring at a higher stage past the obstructions. This can cause channels to become filled with sediment or become clogged with debris causing issues farther upstream from where the initial flooding occurred. Depending on the extent of the flooding, water quality becomes an issue because it becomes necessary to treat contaminated runoff, but depending on the contaminants present this process can be very costly especially when compared to its benefits. In addition to water quality in the runoff poses issues, if any sewer or water treatment plants have been flooded, homes may now not have access to clean water or working restrooms. 4.2.1.5. Geographic Scope of Hazard B1c The extent of urban flooding in Hennepin County really depends on an extremely complex set of interactions between the surface and sub‐surface drainage networks and features of the environment. Urban flooding can be small in geographic scope as in just a few streets or neighborhoods with minor flooding damage, to large areas of entire cities being under water. 4.2.1.6. Chronologic Patterns Urban flooding in Hennepin County typically occurs in the spring and summer months associated with thunderstorms. Springtime urban flooding can come from both snowfall melt and runoff during the spring, a spring thunderstorm that comes before the ground has had time to that completely preventing infiltration, or just a normal thunderstorm (or multiple thunderstorms within a smaller period) with excessive rainfall rates. 4.2.1.7. Historical Data B1d Floods have been documented all the way back to 1776 in Minnesota. However official American records don’t begin until 1873. As mentioned in river flooding, of the 24 State of Minnesota Flood Declarations, Hennepin County has been included in six, with all having urban flooding issues with road and bridge closures. There have been no other naturally caused incidents that are within the scope of this plan. 1965 Flooding (DR‐188) 1969 Flooding (DR‐255) 1997 Severe Flooding, High Winds, Severe Storms (DR‐1175) 2001 Severe Winter Storms, Flooding, and Tornadoes (DR‐1370) 2010 Flooding (DR‐3310) 2014 Severe Storms, Straight‐Line Winds, Flooding, Landslides and Mudslides (DR‐4182) 2016 Severe Storms & Flooding (DR‐4290) 211 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 35 4.2.1.8. Future Trends B1e Urban flooding is a naturally occurring hazard that affects cities and regions around the world, and is expected to become even more problematic in the future. Damages from floods are also increasing as are the number of people who are affected by them. Human‐induced land cover change and climate change are important factors in urban flooding. Rapid population growth and increasing migration from rural areas to cities lead to intense urbanization, which often increases flood risk. According to recent studies, the urban heat island effect and aerosol composition can alter the climate mechanism, which plays an important role in the storm evolution of urbanized regions. Global warming, the other main cause of hydrologic regime change, can induce the acceleration of the water cycle, which can consequently affect the frequency and intensity of future storm events. Research has shown that in the future we may not necessarily see more rainfall, but more rainfall on less days. That is to say that if the monthly average total rainfall is four inches over eight different days, we would now see that four inches come on three or four days. So same amount of rain, just coming more at one time. 4.2.1.9. Indications and Forecasting Currently, the operational method for forecasting flash floods at the National Weather service is to utilize the Flash Flood Monitoring and Prediction software package to compare rainfall estimates with flood‐ induced rainfall accumulation thresholds, known as flash flood guidance values. The success of this guidance depends on both accuracy of radar‐estimated rainfall rates and the flash‐flood guidance values. The National Weather Service Weather Forecast Offices issues all flash‐flood advisories, watches, and warnings for their respective county warning areas. The primary indicator used by forecasters to predict onset of flash flooding, is when radar‐based rainfall estimates exceed flash flood guidance values over f 1, 3, or 6 hours. Flash‐flood guidance is defined as the threshold rainfall required to initiate flooding on small streams that respond to rainfall within a few hours. 212 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 36 4.2.1.10. Detection & Warning The National Weather Service issues flash flood advisories, watches, and warnings. Flood Advisory: Thunderstorms have produced heavy rainfall that may result in ponding of water on roadways and in low‐lying areas, as well as rises in small stream levels, none of which pose an immediate threat to life and property. Flash Flood Watch: Atmospheric and hydrologic conditions are favorable for short duration flash flooding and/or dam break is possible. Flash Flood Warning: Excessive rainfall producing thunderstorms have developed, lead to short duration flash flooding. A warning may also be issued if a dam break has occurred. 4.2.1.11. Critical Values and Thresholds Using thresholds for flooding indicators can be intellectual traps for the uneducated and what constitutes an important threshold in one situation may be unimportant in another. In broad terms, moderately high rainfall rates begin at about 1 inch per hour, and moderately long durations begin at about one hour, but these should be considered only as the crudest of guidelines. Conversation with the local National Weather Service in Chanhassen, MN has concluded that local forecasters tend to look at the rainfall rate and return period more than any amount threshold. It also depends on antecedent conditions. Consensus between the hydrologist and an operation warning forecaster is they look for model outputs to show them at least a 10‐year event as a starting point to get flash flooding. In addition, using one particular source, they use a return period for precipitation to have at least a 20–50‐year event to get flash urban flooding in the Twin Cities Metro area. 4.2.1.12. Prevention To improve water management and protect the sewage system from damage, cities can revamp their underground pipe and drainage systems by separating rainwater from the sewage system. The separation enables the wastewater treatment plant to function properly, without it being overburdened by large quantities of storm water. Other more obvious methods are to keep sewer systems clean of clog up with waste, debris, sediment, tree roots and leaves. 4.2.1.13. Mitigation Areas that have been identified as flood prone areas can be turned into parks, or playgrounds, buildings and bridges can be lifted, floodwalls and levees, drainage systems, permeable pavement, soil amendments, and reducing impermeable surfaces. Reducing impervious surfaces could include the addition of green roofs, rain gardens, grass paver parking lots, or infiltration trenches. Other mitigation strategies include developing a floodplain management plan, form partnerships to support floodplain management, limit or restrict development in floodplain areas, adopt and enforce building codes and development standards, improve storm water management planning, adopt policies to reduce storm water runoff, and improve the flood risk assessment. 213 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 37 4.2.1.14. Response One of the most important things to be done during the initial response is to make sure that people are safe. If their homes have been damages and are unlivable, finding a place for them to stay is among one of the top priorities. Next is the access to places if roads are washed out or still underwater. One complicated factor with flood disasters, is sometimes you do not know how bad the damage is until the water recedes, which can take time and slow the response. Another important part of response is to make sure water supply is available as quick as possible if there has been any contamination. The role of Hennepin County Emergency Management is to coordinate resources that our municipalities may need to accomplish all response needs. 4.2.1.15. Recovery As mentioned in river flooding, recovery from floods can take weeks, to months, to years. Urban flooding is unlike quick disasters (e.g., tornadoes) where you can see the damage immediately, sometimes with urban flooding you must wait for the flood waters to recede to find out what damage there is to recover from. A lot of the time, the longer the water level stays too high, the more consequences are introduced that you must then recover from. 4.2.1.16. References Bumsted, J. M. 1997. Floods of the Centuries.

Silver Spring, MD. 215 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 39 4.2.2. Hazard Assessment: FLOODING, RIVER 4.2.2.1. Definition River flooding occurs when river levels rise and overflow their banks or the edges of their main channel and inundate areas that are normally dry. River flooding can occur from both high precipitation weather events and/or ice/snow melt in the spring. The amount of flooding is usually a function of the amount of precipitation in an area, the amount of time it takes for rainfall to accumulate, previous saturation of local soils, and the terrain around the river system, dam failures, rapid snowmelt, and ice jams. Over 750 of Presidential Disaster Declarations result from flooding. River flooding is classified as Action, Minor, Moderate, or Major based on water height and impacts along the river that have been coordinated with the National Weather Service. Action means the National Weather Service, or a customer/partner, needs to take mitigation action in preparation for potential river flooding. Minor river flooding means that low‐lying areas adjacent to the stream or river, mainly rural areas and farmland and secondary roadways near the river flood. Moderate flooding means water levels rise high enough to impact homes and businesses near the river and some evacuations may be needed. Larger roads and highways may also be impacted. Major flooding means that extensive rural and/or urban flooding is expected. Towns may become isolated and major traffic routes may be flooded. 4.2.2.2. Range of Magnitude United States o Most destructive flood: Mississippi River, 1927 (500 killed; 600,000 homeless) o Costliest Flood: Great Mississippi & Missouri River Flood of 1993 ($30.2 billion) Minnesota o Most destructive flood: 1997 Red River Flood (58 of 87 counties in Minnesota Federally Declared Disasters) o MN costliest flood: 1997 Red River Flood ($2 billion) 4.2.2.3. Spectrum of Consequences B2b River flooding can affect both people and property. Losses in both wildlife and livestock can also occur, which can drastically affect the economy. In addition, road washouts, power and water outages can also be common with river flooding. 4.2.2.4. Potential for Cascading Effects There is high potential for cascading consequences from river flooding. Depending on severity, there could be public health sanitation problems, landslides, food spoilage and food production shortages from farmland being underwater. 216 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 40 4.2.2.5. Geographic Scope of Hazard B1c River flooding occurs across all of Hennepin County. Three major rivers create Hennepin County borders on the northwest, south and east side. Those include the Minnesota, Crow, and Mississippi Rivers. In addition, several creeks and streams across Hennepin County have a history of flooding, which have caused damage to property. Some of those include the Minnehaha Creek, and Nine Mile Creek. All these rivers and creeks are susceptible to early spring snow‐melt flooding as well as summer and fall storm seasons. 4.2.2.6. Chronologic Patterns River flooding can occur because of both snowmelt and high precipitation events which makes the flood season start from early spring to early winter. It of course depends on how warm we start to get in the spring how early, to when we start to get below freezing in the winter. For example, if there is more than average snowfall/snow depth tied together a spike in temperatures during the early spring, we are melting snow without having a fully thawed out ground, making soil impervious, which increases the runoff and subsequently increasing chances for flooding. 4.2.2.7. Historical Data/Previous Occurrence B1d Floods have been documented all the way back to 1776 in Minnesota. However official American records don’t begin until 1873. Minnesota has seen twenty‐four Disaster Declarations due to flooding, six of which have been in Hennepin County. There have been no other naturally occurring incidents that are within the scope of this plan. 1965 Flooding (DR‐188) The Mississippi River at Fridley crested at 20 ft. on April 17th, 1965, which was 4 ft. over flood stage. On April 15, the Minnesota River at Savage crested at 719.40 ft., over 17 ft. above flood stage (702 ft.), and 7 ft. above major flood stage (712 ft.). A day later April 16th, the Mississippi river at St Paul crested at 26.01 ft., 12 ft. above flood stage (14 ft.) and 9 ft. above major flood stage (17 ft.). The St Croix River at Stillwater followed suit with a record crest of 94.10 ft. on April 18, is 7 ft. above flood stage (87 ft.) and 5 ft. above major flood stage (89 ft.). 1969 Flooding (DR‐255) The Mississippi River at Fridley crested at 17.50 ft. on April 14, 1969, which was 1.5 ft. over flood stage. Crow River crested at 16.5 ft. on April 11, 1969, which is 6.5 ft. over flood stage. 1997 Severe Flooding, High Winds, Severe Storms (DR‐1175) The Mississippi River at Fridley crested at 17.10 ft. on April 10, 1997, which is 1.1 ft. over flood stage. 217 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 41 Crow River reached flood stage of 10 feet on 4/4/97 at Rockford which is the river monitoring point. The river crested at 14.4 feet on 4/9/97 which was the fifth highest crest ever recorded. The river subsided to below flood stage on 4/20/97. Substantial flooding occurred at a golf course in the town of St. Michael. (NCDC Storm Events) 2001 Severe Winter Storms, Flooding, and Tornadoes (DR‐1370) The Mississippi River at Fridley crested twice. First at 16.60 ft. on April 15, 2001, and second at 16.40 ft. on April 28th, 2001, 0.6 and 0.4 ft. over flood stage respectively. Four factors contributed to the flooding of 2001: significant autumn precipitation, heavy winter snowfall, less than ideal snowmelt scenario, and record‐breaking April precipitation (http://climate.umn.edu/doc/journal/flood_2001/flood_2001.htm). April 16th the Crow River at Rockford, MN crested at 14.5 feet with a peak discharge at 13,100 ft3/s which is 4.5 ft. over flood stage. 2010 Flooding (DR‐3310) Crow River at Rockford reached 13.99 ft. on March 22, 2010, which was 3.99 ft. over flood stage. 2014 Severe Storms, Straight‐Line Winds, Flooding, Landslides and Mudslides (DR‐4182) Crow River at Rockford crested at 15.08 ft. on June 25th, 2014, which was 5.08 over flood stage. 4.2.2.8. Future Trends B1e Changes in river flooding can be caused by changes in atmospheric conditions, land use/land cover, and water management. These changes can occur in tandem, or individually which makes it difficult to determine which factor acts as the driving force of changes in river flooding behavior. However, long‐term data does show and increase in flooding in the norther half of the eastern prairies and parts of the Midwest. Even with data showing days with heavy precipitation increasing, this trend does not strongly relate to changes, or increases, in river flooding. One conclusion for this is the mismatch of seasons with which the high precipitation events occur and most likely season for flooding in most river basins within our region8. For example, the northern Great Plains typically sees peak river flooding during spring snowmelt, however, generally the heaviest daily rainfall events occur during the summer. When considering the issue of future river flood hazard changes, it is important to recognize that urban and rural land‐use impacts, and water management have significant influence on river flood behavior. While precipitation and flooding have been increasing in the northern half of the eastern prairies, general circulation models do not show this as an area expected to have a substantial increase in runoff in the twentieth‐century or the twenty‐first century forecast. 4.2.2.9. Indications and Forecasting River Flooding typically occurs hours to days after a high precipitation event. Warnings for river floods can often provide much more lead‐time that those for flash flooding. 4.2.2.10. Detection & Warning 218 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 42 The National Weather Service issues flood advisories, watches and warnings16. Flood Advisory: Thunderstorms have produced heavy rainfall that may result in ponding of water on roadways and in low‐lying areas, as well as rises in small stream levels, none of which pose an immediate threat to life and property. Flood Watch: Atmospheric and Hydrologic conditions are favorable for long duration areal or river flooding. Flood Warning: Long duration areal or river flooding is occurring or is imminent, which may result from excessive rainfall, rapid snow met, ice jams on rivers or other similar causes. 4.2.2.11. Critical Values and Thresholds The National Weather Service uses flood categories to communicate/categorize the severity of flood impacts in the corresponding river/stream reach. The severity of flooding at a given stage is not necessarily the same at all locations along a river reach due to varying channel/bank characteristics or presence of levees on portions of the reach. Therefore, the upper and lower stages for a given flood category are usually associated with water levels corresponding to the most significant flood impacts somewhere in the reach. The flood categories used by the National Weather Service are: Minor Flooding ‐ minimal or no property damage, but possibly some public threat (e.g., inundation of roads). Moderate Flooding ‐ some inundation of structures and roads near stream. Some evacuations of people and/or transfer of property to higher elevations. Major Flooding ‐ extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations. Record Flooding ‐ flooding which equals or exceeds the highest stage or discharge observed at a given site during the period of record. The highest stage on record is not necessarily above the other three flood categories, it may be within any of them or even less than the lowest, particularly if the period of record is short (e.g., a few years). It is also important to note that minor, moderate, major flood categories do not necessarily exist for all forecast points. For example, a location with a permanent levee may begin to experience impacts at moderate flooding level. 4.2.2.12. Prevention Most prevention methods of river flooding fall under mitigation actions. See Mitigation below for methods of prevention. 4.2.2.13. Mitigation There are many ways to mitigate flooding hazards. Two techniques are hard and soft engineering mitigation techniques. Hard engineering techniques include building dams, levees, wing dykes, and diversion spillways. Soft engineering techniques include floodplain zoning, afforestation, wet plain restoration, river restoration, and removal of properties in flood prone areas. 219 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 43 4.2.2.14. Response Hennepin County Emergency Management Capabilities Situation monitoring Station (SMS) Immediate Impact Reconnaissance Teams Hennepin County Emergency Operations Plan 4.2.2.15. Recovery Recovery from floods can take weeks to months to years. One complicating factor when it comes to river flooding, is unlike quick disasters (e.g., tornadoes) where you can see the damage immediately, river flooding you must wait for the floodwaters to recede to find out what damage there is to recover from. A lot of the time, the longer the water level stays too high, the more consequences are introduced that you must then recover from. 4.2.2.16. References Bumsted, J. M. 1997. Floods of the Centuries.

Meteorological Hazards 4.3.1. Hazard Assessment: CLIMATE CHANGE 4.3.1.1. Definition Climate change is a significant and ongoing change in the long‐term statistical and/or spatial behavior of weather patterns and variables, as global temperatures rise in response to the intensified combustion of fossil fuels and deforestation, both of which increase concentrations of atmospheric carbon dioxide and other greenhouse gases. The increasing global temperatures have, in turn, added additional moisture to the air through higher evaporations rates, and modified patterns of global atmospheric circulation. Climatic Background Hennepin County has a highly variable, continental‐type climate with seasonal extremes and a wide range of weather hazards. Its position near the center of the continent, and halfway between the Equator and North Pole, subjects it to a wide variety of air mass types throughout the year. During a single year, Hennepin County will experience heavy snow, frigid wind chills, howling winds, intense thunderstorms, torrential rains, and heat waves, as well as dozens of bright and sunny days. In addition to extreme variations between our seasons, Hennepin County’s climate also can include large variations from one year to the next, or even at decadal and multi‐decadal scales. The extremely dry years of 1910, 1936, 1976, and 1988 each were followed within 1‐3 years by extremely wet ones. In a six‐year span of the 2010s, Hennepin County experienced its warmest November through March on record in 2011‐12, its 5th coldest on record in 2013‐14, and its 4th warmest on record in 2015‐16. Climate Change in Hennepin County In Hennepin County, climate change has meant distinct, measurable trends towards warmer, wetter, and more humid conditions on average, even as occasional swings towards dry or cold conditions continue to be part of the climate. As shown in TABLE 4.3.1A, county‐averaged temperature and precipitation have increased by 3.1° F and 3.0 inches, respectively since 1895. The warmest year, winter, and spring, and the wettest summer and winter, have all occurred since the year 2000. Additionally, nine of the county’s 10 warmest years and seven of the 10 wettest years from 1895 through 2023 occurred after 1970, with the vast majority occurring after 1990. The county’s most extreme precipitation events also occurred during this period, with major flash‐flooding in 1977, 1987, 1997, 2014, and 2016. Record‐level humidity extremes occurred more frequently from 2000 through 2023 than at any other time in 121 years of record. 222 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 46 TABLE 4.3.1A Annual, spring, summer, fall, and winter temperature and precipitation averaged over Hennepin County showing the 1991‐2020 average values, the total change from 1895‐2023, the maximum values and the minimum values.

Some hazards appear strongly linked to climatic change while other hazards have yet to show any influence at all. In general, the most notable associations include cold weather extremes becoming less severe or less frequent, and extremes of precipitation becoming more severe or more frequent. Humid heat waves have a moderately‐strong and increasing association with climate change, because of increases in humidity. Other common hazards, including tornadoes, hail, and strong thunderstorm winds; drought; and summer high temperature extremes, show little or no long‐term change in frequency or magnitude yet. GRAPHIC 4.3.1A Confidence that climate change has already impacted common Hennepin County weather/climate hazards through 2023. Provided upon request by Minnesota State Climatology Office. 223 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 47 Warming in Hennepin County County‐averaged statistic indicate Hennepin County has warmed a total of 3.1° F since 1895, or at an average rate of +0.24° F per decade, which exceeds global and national averages. As illustrated in GRAPHIC 4.3.1B, using the same data source, nine of the 10 warmest years on record—including the warmest year in 2012—have occurred since 1990. GRAPHIC 4.3.1B Annual temperature, averaged over Hennepin County, 1895‐2023, with the trendline showing average rate of change over the period of record. Table at right shows ten warmest years. Data from Minnesota DNR Climate Trends Tool (https://arcgis.dnr.state.mn.us/ewr/climatetrends/). Although temperatures are increasing in every season, winter (December through February) has warmed approximately three times faster than summer (June through August), with a total warming of 5.0° F versus 1.7° F. Daily overnight low temperatures have also increased about three times faster than daily high temperatures. The most extreme differences in warming rates are between winter low temperatures, which have increased by an average of 6.4° F since 1895, and summer high temperatures, 224 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 48 which have shown very slight decreases over that same period. Winter and nighttime‐driven warming is consistent across the planet and is especially pronounced in areas with long and severe winters—when surface heat that would normally escape into space is trapped by the growing concentration of greenhouse gases. This warming has reduced the availability and depth of cold air masses, such that cold air outbreaks are not as frequent or severe as they were historically, while mild winter air masses are now more frequent and often warmer than was typical historically. For instance, GRAPHIC 4.3.1C shows that daily minimum temperatures of ‐20° F or lower are now less common in the Twin Cities than in any other period back to 1873. GRAPHIC 4.3.1C Frequency of ‐20° F low temperatures in the Twin Cities. Data source: Applied Climate Information System, accessed via https://www.dnr.state.mn.us/climate/historical/acis_stn_meta.html. Across Minnesota and the region, this warming has led to far more warm records than cold records being set. Since the year 2000, the Twin Cities airport has set 6.7 times more records for highest daily maximum and highest daily minimum temperature, than for lowest daily minimum and lowest daily maximum temperature (shown in GRAPHIC 4.3.1D). These recent years represent just 16% of the station history but account for 33% of the warm records and only 5% of the cold records.

The average summer daily maximum or high temperature (June through August) shows a very slight decrease over time. This observation is matched by the fact that the count of daytime high temperatures reaching or exceeding 90° F in the Twin Cities has shown no trend since peaking in the 1930s. Meanwhile, average summer minimum or low temperatures show have increased by 3.7° F since 1895, which exceeds the rate of annual average warming for the county. Therefore, the summer warming experienced in the county so far is attributable to warmer nights, which result in higher minimum temperatures. GRAPHIC 4.3.1E shows summer temperature behavior over in the Twin Cities and Hennepin County.

As shown in GRAPHIC 4.3.1F, using the same data source, five of the 10 wettest years on record, including each of the top‐3 and four of the top‐5, have occurred since 1990. Only one year since 1990 has made the list of 10 driest years (2022 was 10th driest, not shown). The long‐term Twin Cities climate station, currently at the International Airport, set all‐time annual precipitation records in 2016, and then again in 2019, and finished the 2010s as the wettest decade on record since the 1870s. Although at least one month from each season has increasing precipitation, the strongest seasonal increases have been in spring and summer, whereas average precipitation during fall and winter hardly changed or decreased slightly from 1895 through 2023.

Table at right shows ten warmest years. Data from Minnesota DNR Climate Trends Tool (https://arcgis.dnr.state.mn.us/ewr/climatetrends/). Daily and multi‐day extremes of rain have become more common in recent decades as well. Rainfall records for the Twin Cities go back to 1871, but the period since 1970 dominates the heavy rain statistics, with four of the top‐six daily rainfall totals occurring during that period, including the two largest events on record—which led to significant and even catastrophic flooding. As shown in GRAPHIC 4.3.1G, annual precipitation and the number of days with heavy rain, or at least one inch of precipitation, both increased during the most recent several decades. Seasonal snowfall also has increased and remained historically high during the period of strong winter warming and the great climatic change in Hennepin County. With snowfall records back to 1884‐85, each of the top three, tour of the top five, and 14 of the 20 snowiest seasons on record occurred after 1980. Most recently, the 2022‐23 winter was third snowiest on record in the Twin Cities, with 90.3 inches. The period 1980‐2023 represents just 32% of the station history of the Twin Cities, but accounts for 70% of the top‐20 seasonal snowfall totals. Daily and multi‐day snowfall extremes are also more common in recent decades. Eight of the 10 largest daily snowfalls on record occurred after 1980, including each of the top four. GRAPHIC 4.3.1H shows how days with heavy snow and seasonal snowfall have hit historical high marks only recently. GRAPHIC 4.3.1G (top) Annual precipitation and average number of days receiving at least one inch of precipitation, by decade in the Twin Cities.

In fact, as can be seen in GRAPHIC 4.3.1G above, even with the drought episodes, annual precipitation during the early 2020s is still higher than every decade from the 1920s through the 1960s. This is because the dry conditions have been episodic, generally limited to the warm season, and often followed by very wet conditions in the cooler months. 29.73 26.17 26.76 31.50 27.74 25.17 23.88 25.72 24.97 26.85 27.18 29.88 31.14 29.57 34.31 27.11 0 1 2 3 4 5 6 7 8 9 0 5 10 15 20 25 30 35 40 Days with 1+ InchAnnual Precipitation (in.)Twin Cities Average Annual Precipitation and Heavy Rain Days by Decade Annual Precipitation Average Number 1‐inch Precip Days 39.72 40.27 43.40 44.91 40.02 37.47 36.90 44.66 49.05 55.68 61.45 52.65 47.46 54.36 60.18 1 1.5 2 2.5 3 3.5 4 4.5 5 0 10 20 30 40 50 60 70 Average Number of DaysSeasonal Snowfall (in.)Twin Cities Average Seasonal Snowfall and Heavy Snow Days by Decade Seasonal Snowfall Days with 4+ Inches 229 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 53 For instance, the six months from May through October of 2022 were the 4th driest on record in Hennepin County, with the US Drought Monitor indicating Extreme Drought, the second‐highest level, over much of the county. A very wet period quickly followed it, however, and the six months from November through April 2023 became the fourth wettest on record. Dry conditions set in again, with May through August 2023 ranking 3rd driest on record, followed by much‐above‐normal precipitation in September and October, and then the third‐wettest December on record. This oscillation between wet and dry regimes is illustrated in GRAPHIC 4.3.1I. GRAPHIC 4.3.1I Sequential episodes of very dry and very wet conditions during 2022 and 2023 in Hennepin County. Source: DNR Climate Trends (https://arcgis.dnr.state.mn.us/ewr/climatetrends/). Humidity Increased humidity has been notable during all seasons in recent decades. From 2000 through 2023, the Twin Cities long‐term climate station measured more daily record‐high and fewer daily record‐low dew point temperatures (a measure of humidity) than any other time since records began in late 1902. Of the 14 documented days with extreme humidity yielding at least one hourly 80° F dew point reading, 10 have occurred since 1990, and none occurred prior to the 1960s. Even though the highest air temperatures of summer and the number of 90° or 95° F days has not increased over the long‐term, extremely humid conditions have at times combined with hot air masses to yield unprecedented Heat Index values, which measure what the air feels during heat waves. On July 19, 2011, Flying Cloud airport measured a Heat Index of 122°F, while the Twin Cities airport measured 119 °F. On August 22, 2023, another intense heat wave fueled by high moisture and dew points, sent Heat Index values into the upper 110s F across the county, with 120° F recorded at the Hennepin‐West Mesonet stations located in Hanover and at the MSP Airport. Record humidity has not been confined to the summer, when it is most noticeable to humans, but in fact ‐50% 4th driest 54% 4th wettest ‐55% 3rd driest 33% 20th wettest ‐80% ‐60% ‐40% ‐20% 0% 20% 40% 60% June ‐ October 2022 November 2022 ‐ April 2023 May ‐ August 2023 September ‐ December 2023DepartureRecent Precipitation Departures from 1991‐2020 Averages, and Ranks from 1895 to 2023 Hennepin County 230 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 54 has been observed throughout the year with increased frequency during recent decades. Most notably, in 2021 latest date a 50° F dew point had ever been recorded at the Twin Cities long‐term station advanced 10 days, to December 15th, in 2021, and then 10 more days, to December 25th in 2023. The latest 60° dew point on record was measured on November 10th of 2022. The earliest date to measure 50° F was February 20, 2017, and the earliest 60° F dew point occurred on March 17, 2012. Increased humidity is not just a human comfort concern; it also has implications for precipitation and severe weather frequency, because water vapor is what fuels precipitating weather systems. The high dew points recorded on December 15, 2021, were associated with an unprecedented winter outbreak of tornadoes and damaging thunderstorm winds in southeastern Minnesota. The December 25, 2023, high dew points were associated with an unusually heavy December rainfall event. The 60° F dew point on March 17, 2012, was matched or nearly matched for several more days, and fueled a rash of rare mid‐ March severe thunderstorms across Minnesota. 4.3.1.2. Range of Magnitude Climate change is unlike other hazards because it is not episodic and does not “strike.” Rising global temperatures represent a constant and increasing force that is always present, even when it is not obviously detectable in each weather pattern or climatological data set. The magnitude of climate change is generally measured as the total warming of the earth’s atmosphere above “pre‐industrial” temperatures, with that period reflecting 1850‐1900 averages in some data sets, or simply beginning in 1880 in other data sets. These temperatures are closely, but not exclusively linked to the global concentrations of carbon dioxide, as measured at the Mauna Loa observatory in Hawaii. Carbon dioxide levels have increased annually for decades, but while global temperatures have increased steadily, natural factors, like El Niño and some ocean circulation phenomena, drive normal fluctuations the global heat content. Virtually all data sets show that the earth has warmed between 1.1° and 1.3° C (2 – 2.3° F), and most show a continued warming rate 0.1 to 0.2° C (.18° to 0.36° F) per decade. These warming magnitudes and rates are smoothed to remove the influence of large short‐term variations, including the world‐record temperature spikes observed in 2023, when global temperatures exceeded 1.5° C above pre‐industrial levels at times, and when the average anomaly was 1.3° to 1.54° C for the year. Translating the magnitude of warming globally, into weather or climate impacts experienced in Hennepin County is not straightforward. The science of “attribution,” or determining how much of a given trend, change, or event, is attributable to human‐caused climate change, has largely focused on events that to date have not included the area. These studies usually indicate that climate change is responsible for all, or nearly all long‐term warming in non‐urbanized areas, and that it enhances or intensifies some types of extreme weather events but does not “cause” them. Given that the Twin Cities airport climate station is and has always been in an urban, built‐up area, we know that some of the temperature increase seen there is because of urban “heat island” effects and not the changing global climate. At rural stations, and in homogenized data sets like the county‐averaged one 231 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 55 referenced in other sections in this chapter, the urban warming “bias” is minimized or even non‐existent. Rural counties to the west have similar long‐term temperature increases to Hennepin County. It is therefore likely that the vast majority of the 3.1° F of average annual warming and the other seasonal warming reported for Hennepin County results from human‐caused climate change. Applying findings from attribution studies in other areas to common hazards in Hennepin County suggests the following: Climate change is likely making humid heatwaves in Minnesota more severe by increasing Heat Index values by 4°‐6° F over what would have been observed without a warmer global climate. This also has the effect of increasing the probability of occurrence dramatically. Extremes of precipitation, including snowfall, may be 10‐15% larger because of the higher water content of the atmosphere due to rising global temperatures. o Similarly, the damaging snows of December 13‐16, 2022, to the north of the Twin Cities may have had two climate changes making them more likely: 1) the increased availability of moisture because of higher global temperatures, and 2) the winter warming that caused the snow to be wetter, heavier, and thus more destructive. Out‐of‐season events that result from unusually warm conditions, like the severe weather outbreak of December 15, 2021, or a record‐breaking heat wave in early October of 2023, may have been much more likely because of climate change, and therefore would have been substantially less probable without human‐caused warming. Any events of these types will become more probably with continued warming, and that continued warming would make larger contributions to future events, meaning potentially greater extremes of precipitation and humid heat waves in the decades ahead. 4.3.1.3. Spectrum of Consequences B2b In Hennepin County, climate change has led to warmer conditions in general, especially during winter; more precipitation, including during drought years; greater extremes of rain and snow; and more intense humidity‐driven heatwaves. Additionally, the seasonal ranges of heatwaves and severe weather events have expanded. Even though year‐to‐year and multi‐year variations will continue, these changes are projected to continue as well, with an enhancement of some hazards as the world warms. Warmer winter conditions pose some benefits for human comfort and safety but pose recreational risks because of dangerous lake ice that may be unsuitable for fishing and ice skating. Natural systems dependent on cold weather to keep out competitive species and predators also suffer from enhanced winter warming, which can alter ecosystems and natural resources. Increased rain and snow extremes mean roads and their supporting infrastructure may face increased damages if they are not built to higher design standards. Heavy, wet snow, as occurred in the 2022‐23 winter, can damage trees, knock out power, and overwhelm some structures with snow loads. Greater precipitation totals during wet years also would imply high water levels on area lakes and streams, increasing chances for erosion, pollution from runoff, degraded water quality, stream bank failure, landslides, and residential flooding. 232 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 56 Humid heatwaves pose significant dangers to those working, recreating, or living outside. Increases in these dangerous conditions will affect larger proportions of the population, as the risk moves from those most vulnerable, to the general population, and even those in excellent physical condition. Following are some consequences expected with climate change in Hennepin County: ● Less reliable and more dangerous lake ice ● More periods of bare/snow‐free ground, allowing frost to penetrate to great depths during cold outbreaks. ● Expansion of the heavy rainfall season, leading to enhanced peak stream flows, and altered timing of normal flow regimes. ● Increased runoff and flash‐flooding as the largest events intensify and become more common. ● Water infrastructure damage from intense rainfall events ● Agricultural stress, from shifting crop ranges, heat, drought, and extreme rainfall ● More days with high water vapor content and heat index values ● Greater summer cooling costs, more days requiring cooling. ● New invasive species, both terrestrial and aquatic, especially those acclimated to warmer climates or those that were cold weather limited. ● “Hyper‐seasonality,” as warm conditions develop during the “off‐season,” leading to bouts of heavy rainfall or severe weather, followed by wintry conditions. ● Increase in frequency of freeze‐thaw cycles, as winter is increasingly infiltrated by warm conditions. Some positive benefits of a changing climate might include fewer automobile accidents and damage as more winter precipitation falls in the form of rain rather than snow or ice. However, warmer winters doesn’t necessarily mean rain instead of snow, it could mean more ice storms, which would lead to dangerous driving conditions and power outages due to down power lines. Also, rain falling in the winter can be disastrous if it is followed by sharply colder air and a “flash‐freeze.” Additionally, summertime air temperatures are extremely likely to begin increasing in the decades ahead, and possibly before 2030. When these hotter summers pair with normal dry swings in the climate, they will increase drought severity and water demand, while also increasing the potential for wildfire (see drought section of risk assessment). Some new research (as of 2023) indicates that extreme windstorms associated with thunderstorms may become more probable, larger, and possibly more intense as the world continues warming. These studies indicate that, as a result, a given extreme wind event may have the ability to affect more people and more property than in the past—not accounting for the growth and the expansion of Hennepin County’s population. In recent years, smoke from wildfires has degraded air quality, occasionally to dangerous levels in Hennepin County. Climate models project that wildfires and downstream smoke infiltration will become more common as northern forests are weakened by warming winters, more severe heat waves, and even precipitation extremes. Increased smoke particulates are a health hazard for everyone, but disproportionally affects those with respiratory challenges, limited mobility, other health conditions, and those who cannot shelter from the smoke. 233 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 57 4.3.1.4. Potential for cascading effects Climate change enhances some hazards, so please see chapters on Extreme Heat, Straight‐line winds, Extreme rainfall, and non‐convective winds, to understand the potential cascades that climate change may enhance or cause. The most novel group of cascading effects to consider with climate change is when warm conditions produce a meteorological situation previously unheard of or quite rare. Winter severe thunderstorm events, for example, may be more likely as winters continue warming, but to occur, they would almost certainly be accompanied by a powerful low‐pressure system capable of producing plunging temperatures and strong winds. Communities facing power outages, debris clean‐up, and even search‐and‐rescue operations may then have to face with cold weather hazards. 4.3.1.5. Geographic scope of hazard B1c Climate change is a global hazard and influences weather and climate patterns in some way virtually everywhere. In Minnesota, the greatest warming has been in the northern part of the state, and the largest precipitation increases have been in the southeastern and central portions of the state. However, the entire state of Minnesota, including all of Hennepin County is at risk from increased precipitation extremes, more intense humid heat waves, and the seasonal expansion of severe thunderstorms and heat. 4.3.1.6. Chronological patters (seasons, cycles, rhythm) Warming is occurring year‐round, though the most pronounced changes have been during winter. It should be noted that the area’s climate exhibits natural high variability, and that variability will continue, even as Minnesota warms. It should also be noted that hazard risk does not necessarily follow the cycle of greatest warming. For instance, damaging rains are far more likely in the summer than the winter. 4.3.1.7. Historical Data/Previous Occurrence B1d The year 2012 may be thought of as a preview of the years and decades ahead. The 2011‐12 winter was warm and short, with bouts of 50s and 60s observed throughout Minnesota during January. March that year saw 8 record high temperatures in Minneapolis, and 8 days above 70 degrees. Throughout the region, March 2012 obliterated long‐standing daily and monthly temperature records. The warmth continued through the remainder of the spring and into the summer, with over 30 days above 90 degrees in parts of Hennepin County, and 2 days above 100 at MSP. This was the first summer with multiple 100‐degree readings since the summer of 1988. Others may consider the late 2010s to be representative of the future, because: Based on the Midwest chapter from the 2014, 2018, and 2023 National Climate Assessment, a review of other recent research into the region, and analyses of quality‐controlled, nationally standardized, and publicly available data, the recent trends can be described as follows. 234 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 58 ● Bouts of extreme cold in Hennepin County and throughout Minnesota and the region are now at an all‐time low in terms of both frequency and severity. Of all changes, the loss of cold weather extremes has the strongest link with climate change. ● Extreme rainfall episodes have become both more intense and more frequent, and Minnesota has seen seven “mega‐rainfall” events since the year 2000. Changes in extreme rainfall behaviors are strongly linked to climate change. ● A general increase in annual and seasonal snowfall has been punctuated by an uptick in the size and frequency of large snowfall events. This is likely related to the presence of warmer air and more water vapor during winter, which provides more energy to passing low pressure systems capable of producing snow. ● Severe thunderstorms and tornadoes pose challenges to long‐term analyses because of changes in reporting procedures and detection technologies over time. That said, Minnesota has been in a pronounced severe weather lull since the summer of 2011, which followed a very active spring and record‐setting year for tornadoes in 2010. Confidence in the link between climate change and observed severe weather trends is low. However, the severe weather season has expanded aggressively in recent years, with record‐early tornadoes in Minnesota on March 6, 2017, and record late tornadoes (by 30 days) on December 15, 2021. ● Humid heat waves have increased in severity and frequency, in response to higher humidity. Summertime high temperatures and the number of hot days has not changed yet. ● Despite three straight years of significant growing season drought in 2021‐2023, Hennepin County still does not have a long‐term trend towards increased drought frequency or severity. These are just some examples of the effects of climate change in Hennepin County. 4.3.1.8. Future trends/likelihood of occurrence B1e Projections of future climates from multiple sources indicate that the area is likely to continue to see a rapid erosion of winter extreme cold temperatures, and it is expected that Hennepin County will fail to reach previously common benchmarks by increasingly large margins. Extreme rainfall is projected to increase, but it should not be expected to do so on a year‐after‐year basis. Instead, climate change is increasing the long‐term frequency and magnitude of these events, meaning that storms of a certain size may come every 10‐20 years instead of every 50 years. By mid‐century, the area should receive an additional 3‐8 days per decade with rainfall in the top 2% of the historical distribution (GRAPHIC 4.3.1J). Thus, the expectation is that unprecedented rainfall events will occur at some point this century, but their likelihood in the next decade will be limited by their overall statistical rareness. GRAPHIC 4.3.1J Average difference in number of days per year by mid‐century (2040‐2070) with rainfall in upper 2% of distribution. 235 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 59 Snowfall extremes should continue to increase as well, although the warming of winter in general and the effect of increased winter rains should eventually begin decreasing seasonal snowfall. However, even the most aggressively warm model scenarios show that snow will be a major if not dominant winter precipitation through much of the century. Severe convective storms and tornadoes are unlikely to remain at the current low incidence rates, and a “rebound” appears likely within the next decade, based on historical frequency alone. The association between this rebound and climate change will remain unclear, however. It is increasingly clear that severe convective storms will have expanded seasonal and geographic ranges. It is possible, based on new research, that extreme straight‐line thunderstorm winds will be larger and/or more intense as the climate continues warming. Humid heat waves have already begun increasing in response to greater available humidity. Projections indicate that summer temperatures are likely to increase significantly in Minnesota as well during the 21st century. It remains unclear when these trends would begin, given a lack of any recent trends toward increasing summertime high temperatures. However, projections indicate that by mid‐century, the Twin Cities should expect 5‐10 additional days per year above 95° F, which would more than double current frequencies (GRAPHIC 4.3.1K) 236 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 60 GRAPHIC 4.3.1K Difference in number of days per year by mid‐century (2040‐2070) maximum temperatures above 95° F. Like severe convective storms, drought has shown no trend towards increasing in frequency, severity, duration, or areal coverage in recent decades. This is because the increases in precipitation have overwhelmed even recent significant drought episodes. Projections, however, indicate that drought will at a minimum become more severe in the future—when it occurs. This increase would be in response to the inevitable increase in summertime high temperatures. It remains unclear whether the actual frequency of drought conditions will increase. Projected increases in the number of consecutive dry days during dry spells suggest that drought frequency may increase, in the form of short, “flash” drought episodes, as have been common in the early 2020s (GRAPHIC 4.3.1L). GRAPHIC 4.3.1L Difference in number of consecutive days per year by mid‐century (2040‐2070) with less than 0.01 inches of precipitation. An increase in this variable is associated with an increase in the chance of drought in the future. 237 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 61 Projected changes in the same weather hazards that were shown and discussed previously are shown in GRAPHIC 4.3.1M, along with confidence associated with the projections. Highest scientific confidence is in the continued warming of winter, the continued loss of cold weather extremes, and continued increases in extreme rainfall, leading to occasional unprecedented events. Increases heat waves are projected with high confidence, because of both the increases in humidity already ongoing, and the increases in summer temperature extremes projected unanimously by climate models. With these increases in heat extremes, drought becomes somewhat more likely too, as described above; the severity of drought should increase as summer temperatures do, but it is unclear whether drought frequency will increase. As the century wears on, heavy snow events may continue being more extreme, but they should become less frequent as winter warms even more. Confidence remains moderately low with severe thunderstorms in general, even though seasonality will continue changing. GRAPHIC 4.3.1N combines information known about observed and projected climate trends in Minnesota. GRAPHIC 4.3.1M Confidence that various common Minnesota weather hazards will be impacted by climate change through 2070. 238 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 62 GRAPHIC 4.3.1N Confidence that various common Minnesota weather hazards will be impacted by climate change beyond 2026. 4.3.1.9. Indications and Forecasting Climate change is known to be ongoing and is continuously monitored by climatologists, atmospheric scientists, chemists, biologist, physicists, oceanographers, geologists, and many others. This includes the study of greenhouse gas concentrations, global temperatures, historical events, complex interactions between varying earth systems, and building forecasting models to make sophisticated global, regional, and local projections. The state of the climate and the state of climate science are monitored and reported regularly by thousands of scientists in an array of fields and summarized in assessment reports provided by the Intergovernmental Panel on Climate Change (IPCC) and by the US Global Change Research Program. 239 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 63 4.3.1.10. Detection & Warning The same scientists who contribute to the body of research summarized in the national and global assessment reports also issue statements and warnings regarding the trajectory of the climate and the steps needed to change that trajectory, and/or to protect ourselves against potentially dire consequences of not changing that trajectory. While there are no warnings for climate change like tornado warnings, or flash flood warnings, the IPCC effectively issues warnings with the release of its reports. Some scientists also often issue warnings individually or as smaller groups. The overwhelming consensus among climate scientists is that the climate is changing faster than we can manage and that without fast reductions in greenhouse gas emissions, we will face severe consequences from heat waves, rising sea levels, larger storms, and greater extremes in general. 4.3.1.11. Critical values and thresholds Climate change is an ongoing phenomenon that manifests itself through the persistent change in the statistical behavior of climatic variables. Although no critical values and thresholds exist in Minnesota, the following indicators represent rare and/or uncharted territory in Hennepin County, and would indicate climate change mileposts: February ice‐out, Lake Minnetonka; earliest on record is March 11, 1878 Lack of zero or colder temperature at MSP; has not happened yet, and fewest such readings was two in 2001‐02 Winter average temperature above 27° F ‐‐has only happened once, during “year without a winter” of 1877‐78 Low temperatures failing to reach ‐10° F. Previously it was ‐20° F, and then ‐15°F, but it we now commonly fail to reach these thresholds. No subzero high temperature all winter Summertime minimum temperatures in excess of 80 degrees 90° F in March, 70° F in December or February Tornadoes or severe convective storms at any time from November through February 4.3.1.12. Prevention Preventing climate change requires global coordination and massively reducing the amount of coal, oil, and natural gas burnt for personal, municipal, industrial, and vehicular purposes. However, in the mitigation section you will find strategies to reduce the effects as well as adaptation examples for the changing climate. Hennepin County has a comprehensive Climate Action Plan that includes ambitious goals to reduce greenhouse gas emissions across the county to “Net Zero” (no emissions, or all emissions balanced by reductions) by 2050. While this alone cannot stop climate change, it represents the type of action needed on a larger scale to do so. 240 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 64 4.3.1.13. Mitigation In climate change studies and policy, “mitigation” refers to prevention of the climate change specifically through reducing greenhouse gas concentrations globally. The term “adaptation” generally refers to protecting systems and communities from the changing climate. Hennepin County’s Climate Action Plan lays out steps for not only reducing the greenhouse gas emissions that lead to heat retention and rising global temperatures, but also to adapt the county to the changing climate in a manner intended to improve resiliency and equity, while reducing vulnerabilities. The plan has specific goals to: Protect and engage people, especially vulnerable communities. Enhance public safety. Increase the resilience of the built environment and protect natural resources. Reduce emissions in ways that align with core county functions and priorities. Partner in ways that can be most impactful. The overall risks of future climate change impacts can be reduced by limiting the rate and magnitude of climate change by efforts to reduce or prevent emission of greenhouse gases. Adaptation and mitigation are complementary strategies for reducing and managing risks of climate change. Mitigation can mean using new technologies and renewable energies, making older equipment more energy efficient, or changing management practices or consumer behavior. It can be as complex as a plan for a new city, or as a simple as improvements to a cook stove design. Efforts underway around the world range from high‐tech subway systems to bicycling paths and walkways. Protecting natural carbon sinks like forests and oceans or creating new sinks through green agriculture are also elements of mitigation. Adaptation examples are shown in Table 4.3.1B. Table 4.3.1B.

Hazard Assessment: TORNADO 4.3.2.1. Definition A tornado is defined as a violently rotating column of air that reaches from a wall cloud or updraft base of a severe thunderstorm to the ground. Most tornadoes occur in severe thunderstorms, but not all severe thunderstorms will contain tornadoes. Tornado development depends on either condensed moisture from above and/or dust or debris from the surface to become visible. The wind speeds, width, duration, and length of travel of tornadoes vary widely. The degree of destruction depends on both the strength of the tornado and of what has been hit. Tornadoes may form alone or in some instances they may have satellites or twins that are in proximity. Some regions may experience several tornadoes that form during a few hours in a phenomenon called an outbreak. Outbreaks that repeat over several days are called an outbreak sequence. 4.3.2.2. Range of Magnitude Tornadoes can appear in a variety of shapes and sizes ranging from large wedge shapes with a diameter greater than a mile down to thin rope like circulations. The strongest tornadoes can have wind speeds more than 200 mph. Tornado wind speeds are estimated after the fact based on the damage they produce. Tornadoes are characterized on a scale of 0 (weakest) to 5 (strongest) according to the Enhanced Fujita (EF) Scale. The original Fujita Scale was devised in 1971 by Dr. Ted Fujita of the University of Chicago. The scale gives meteorologist the ability to rate from F0 to F5 based upon the type and severity of damage that the tornado produced. At that time, there were very few actual measurements of tornado wind speeds that he could relate to the damage, but Dr. Fujita used them together with a lot of insight to devise approximate wind speed ranges for each damage category. In subsequent years, structural engineers have examined damage from many tornadoes. They use knowledge of the wind forces needed to damage or destroy various buildings and their component parts to estimate the wind speeds that caused the observed damage. What they found was that the original Fujita Scale wind speeds were too high for categories F3 and higher, which may have led to inconsistent ratings, including possible overestimates of associated wind speeds. With these inconsistent ratings in mind, a panel of meteorologists and engineers convened by the Wind Science and Engineering Research Center at Texas University devised the new Enhanced Fujita Scale, which became active as of February 1, 2007. The EF Scale incorporates more damage indicators and degrees of damage than the original “F” Scale, allowing more detailed analysis and better correlation between damage and wind speed. You can see both scale charts below TABLE 4.3.2A. 246 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 70 TABLE 4.3.2A Fujita Scale The follow are records from around the County as well as Hennepin County.

Spectrum of Consequences B2b The consequences from tornadoes can range from minor damage and injuries to complete destruction and death. Please see the chart below (TABLE 4.3.2B) that correlates the EF rating scale with the expected damage seen. 248 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 72 TABLE 4.3.2B EF Rating Scale 4.3.2.4. Potential for Cascading Effects Beyond the destruction and lives that tornadoes leave behind, there are many cascading events or hazards that can follow. If a tornado takes out a power source and there is expected extreme temperatures to follow, you have now increased the number of people vulnerable to extreme heat or cold event consequences. A lack of power impacts the ability of people to remain warm or cool and may also disable medical equipment. If a tornado disrupts farming is, anyway, this can lead to food shortages and/or disrupt the food chain. As debris is deposited anywhere and everywhere from a tornado, this can lead to water contamination, and a fire hazard with lumber from houses, buildings and trees amongst damaged power lines and gas leaks. Another consequence is the economy impact. Indirect losses that occur from the destruction of a tornado are hard to estimate directly after an event. Losses could include lost production, sales, incomes and labor time, increased commute times and transportation costs from goods having to be rerouted, decreased tourist activity, and utility disruptions. Some people might lose their jobs all together. The decreased economic activity also results in lost taxable receipts and uses up federal disaster relief funds to help the clean‐up, repair, and replacing of loss assets. Loss of production an also result in surging prices due to shortages. A well‐known example of this occurred when refineries were affected by a tornado in the southern United States in 2011, which caused gas prices to rise. 249 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 73 4.3.2.5. Geographic Scope of Hazard B1c The United States has the highest incidence of tornadoes worldwide, with more than 1,000 occurring every year. This is due to the unique geography that brings together polar air from Canada, tropical air from the Gulf of Mexico, and dry air from the Southwest to clash in the middle of the country, producing thunderstorms and the tornadoes. The illustration below (GRAPHIC 4.3.2A) provides all tornadoes that have occurred from 1950‐2012 as plotted by the Storm Prediction Center. GRAPHIC 4.3.2A National Tornado Occurrence Map 1950‐2012 250 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 74 The illustration below (GRAPHIC 4.3.2B) provides all tornadoes that have occurred from 1820‐2014 as listed by Hennepin County Archives. GRAPHIC 4.3.2B Hennepin County Tornado Occurrence map 1820‐2014 4.3.2.6. Chronological Patterns Tornadoes can occur during any time of day and any time of year. However, most tornadoes have occurred in the afternoon hours and during the months of May through August. The graphic below (GRAPHIC 251 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 75 4.3.2C) shows the tornado reports nationally from 1950‐2014. You can see in the chart that tornadoes occur (and are reported) more typically starting in April through September with the greatest months being June and July. These two months are typically identified as Minnesota’s tornado season. GRAPHIC 4.3.2C 4.3.2.7. Historical Data/previous occurrence B1d Native peoples in tornado‐prone areas such as Hennepin County experienced tornadoes and developed oral traditions to explain them. The first written record of an American tornado is from July 8, 1680, in Cambridge, MA. The first officially recorded tornado in Minnesota was sighted near Fort Snelling in Hennepin County on April 19, 1820. Because tornadoes are more numerous in the United States than any other nation, tornadoes have been studied here more than anywhere else. In 1882, the U.S. Army Signal Corps assigned Sgt. John Finley to investigate weather conditions that form tornadoes. Technology limits made the early understanding of tornado anatomy difficult. The adoption of radar revolutionized the study and forecasting of tornadoes. The first US Weather Bureau radar in Minnesota was installed at the Minneapolis‐Saint Paul International Airport in the early 1960s. Air Force meteorologists issued the first tornado forecast in March 1948. The US Weather Bureau followed suit by 1952. Important advancements in understanding tornadoes were made by Theodore Fujita who studied tornado formation and damage across the Midwest in the 1960s and 70s. Modern era radar was installed at the Twin Cities office of the National Weather Service in 1996. In Minnesota and Hennepin County, the record of tornado sightings encompasses nearly 200 years from records kept at Fort Snelling. The local newspaper record, which often contain notices of weather events, goes back over 160 years. In general, early reports are incomplete and may contain some factual errors. 0 100 200 300 400 500 600 700 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec# of ReportsMonth Number of Tornado Reports Per ‐Month 1950‐2014 Storm Data, National Climatic Data Center, MN DNR 2014 252 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 76 As settlement and population density increased, human interactions with tornadoes also increased.

Future Trends B1e When looking at trends of tornado occurrences, one must keep in mind how reporting has changed over the last decade as well as population increase. With more people covering a larger geographical area than 100 years ago, there is bound to be more reports of tornadoes occurring because people are there to see them. There seems to be no trend since 1954 of the occurrences of F1 and stronger tornadoes and increase in tornado reports results from an increase in the weakest tornadoes, F0. If just looking at stronger events being reported, you can run into the problem of changes in tornado damage assessment procedures in trend identification. Taking out changes in population and reporting measures, there is less trend in the number of tornadoes per year, as in there doesn’t seem to be a growing number of tornadoes each year, or less for that matter. Research does show there seem to be more extreme swings in tornadoes per year. While years have always varied in terms of number of tornadoes, they generally fell between a certain range. In the past decade however, researchers have started seeing toad counts that have deviated well outside of that range. Another trend researchers are seeing is the number of tornado days seems to be decreasing, while the number of tornadoes per day has been increasing. Researchers have also been looking into trends on when the ‘tornado season’ starts. The average start days of tornadoes is March 22nd, and that has not changed (tornado season start is defined as first 50 tornadoes of F1/EF1 strength have been reported). However, there have been later and early starts to the season in recent years. Seven of the 10 earliest tornado starts have occurred since 1996, and four of the latest starts occurred between 1999 and 2013 of 60 years of records. 8 6 4 3 22 1 0 1 2 3 4 5 6 7 8 9 F0/EF0 F1/EF1 F2/EF2 F3/EF3 F4/EF4 F5/EF5Number of OccurencesHennepin County Tornadoes 1950 F Scale EF Scale 254 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 78 4.3.2.9. Indications and Forecasting National responsibility for developing tornado indications and forecasts rests with the National Oceanic and Atmospheric Administration/National Weather Service’s Storm Prediction Center (SPC) in Norman, Oklahoma. The SPC issues daily Convective Weather Outlooks. These outlooks give general categories that explain the chances/risk of tornadoes each day. As conditions look to develop more favorable for tornadic storms to occur, the SPC will issue Mesoscale Discussions (MDs). MDs contain a graphical depiction of the mesoscale convective developments, an area affected line, concerning line, valid time, a summary paragraph summary, and a paragraph for a technical discussion. There are five categories of concern issued with the MD: Severe Potential…Watch Unlikely (5 or 20%) Severe Potential…Watch Possible (40 or 60%) Severe Potential…Watch likely (80 or 95%) Severe Potential…Tornado Watch likely (80 or 95%) Severe Potential…Severe Thunderstorm Watch Likely (80 or 95%) Severe Potential…Watch Needed Soon (95%) After an MD is issued, SPC will monitor conditions and if tornadic potential still is likely, they will issue a tornado watch. A tornado watch is issued when atmospheric conditions are favorable for the development of severe thunderstorms capable of producing tornadoes. On average, Hennepin County is included in 4 tornado watches each year. In addition to the SPC’s information about potential for tornadoes, the National Weather Service Forecast Office will issue Hazardous Weather Outlook (HWO) based on their thoughts for the potential of tornadoes occurring. In this discussion, they will highlight the best time, and generally geographic location for storms to occur. 4.3.2.10. Detection and Warning National responsibility for detection and warning of tornadoes falls on the local National Weather Service’s Weather Forecast Offices (WFO). The local WFO for Hennepin County is in Chanhassen, MN. One of the systems the WFO uses to detect tornadoes is RADAR. There are two RADAR sites that the Chanhassen WFO uses, the NEXRAD WSR‐88D and the Terminal RADAR. The NEXRAD WSR‐88D is located at the Chanhassen WFO office, and the Terminal RADAR is in Woodbury and is used daily for incoming aircraft. There are many different products that the NWS can use from these RADARS that help them detect whether a storm has a tornadic signature to it. Another avenue that the WFO uses are spotter reports, or reports from emergency managers. In the metro region, there is an organized amateur radio group called Metro SKYWARN that teach SKYWARN spotter classes to amateur radio operators so they can make reports directly to the local WFO. Hennepin County Emergency Management also trains internal SKYWARN spotters to report to the Hennepin County Emergency Operations Center during activations or directly to the local WFO. If the WFO sees evidence that there is a tornado either on the ground, or the potential, they will issue a tornado warning. A tornado warning means a severe thunderstorm has developed and has either produced a tornado or radar has indicated the presence of atmospheric conditions conductive to tornado development. On average, Hennepin County is in a tornado warning between 30 and 45 minutes a year. Once a tornado warning has been issued, there are a variety of notification systems that notified 255 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 79 automatically in which they then send off the notification of tornado warning as well: Wireless Emergency Alerts (WEA), Outdoor Warning Sirens, Digital Message Signs, IPAWS, and NOAA Weather Radios. In addition to the automatic notification, television and radio station may also begin to broadcast the warning information. 4.3.2.11. Critical Values and Thresholds According to NOAA, there is no single critical threshold values to confirm or predict the occurrence of tornadoes of a particular intensity without looking at damage. The critical values of the F & EF tornadoes scales can be seen above in the Range of Magnitude section. 4.3.2.12. Prevention There is nothing you can do to prevent a tornado from occurring. However, you can prevent some of the consequences from occurring by being prepared. It is crucial to always be aware of the weather forecast and if there is a possibility of severe weather. Further, having multiple methods of receiving weather alerts from official sources is also important. 4.3.2.13. Mitigation While there is no way to prevent a tornado from occurring, you can prevent some of the consequences from occurring by being weather aware for life safety, build safe rooms for sheltering or retrofit walls to safe room standard. Here are some of the ideas from the FEMA Mitigations Handbook Education and Awareness Programs: Conduct outreach activities to increase awareness of tornado risk and impacts. Educate citizen through media outlets. Conducting tornado drills in schools and public buildings Teaching schoolchildren about the dangers of tornadoes and how to take safety precautions. Distributing tornado shelter location information Supporting severe weather awareness week Promoting use of National Oceanic and Atmospheric Administration (NOAA) Weather Radios. Construction of Safe Rooms: Requiring construction of safe rooms in new schools, daycares, and nursing homes. Encouraging the construction and use of safe rooms in homes and shelter areas of manufactured home parks, fairgrounds, shopping malls, or other vulnerable public structures. Encouraging builders and homeowners to locate tornado safe rooms inside or directly adjacent to houses to prevent injuries due to flying debris or hail. Developing a local grant program to assist homeowners who wish to construct a new safe room. Require Wind‐Resistant Building or Retrofitting Techniques: Structural bracing Straps and Clips Anchor Bolts Laminated or impact‐resistant glass.

Response Hennepin County Emergency Management Capabilities Situation monitoring Station (SMS) HCEM Immediate Impact Reconnaissance Teams Mutual Aid 4.3.2.15. Recovery There are two types of recovery, short term, and long term. Initial short‐term recovery can be getting the power back on or cleaning up debris. There are many things to consider when talking about long‐term recovery. Depending on the extend of the tornado and location, large, wooded areas can pose a fire threat, so damaged trees and branches need to be managed. Another important consideration is business recovery. It took Joplin 3 years to be able to re‐build their hospital and high school. Other businesses have been shown the struggle for one or more years after a disaster. Another consideration of recovery is the mental recovery of not only victims, but of the rescue workers that responded and helped during the initial short‐term recovery process. 4.3.2.16.

Hazard Assessment: WIND, EXTREME STRAIGHT‐LINE 4.3.3.1. Definition Extreme straight‐line winds are thunderstorm winds that exceed 70 mph and can reach or exceed 100 mph. Along with damage potential to trees, power lines, vehicles and structures, these winds pose risks to life and safety. Most thunderstorms produce gusty winds from downdrafts of air flowing from the tops of the storm. Some thunderstorms produce winds of 58 mph or stronger, officially making them “severe” by National Weather Service standards. Occasionally, severe thunderstorms will produce destructive winds that far exceed the 58‐mph threshold. These winds are often referred to as “straight‐line winds,” to differentiate them from the cyclonic, turning winds of a tornado. Extreme straight‐line winds can indeed produce tornado‐like damage. Extreme thunderstorm winds can be highly localized, or widespread along an arc of storms extending dozens of miles or concentrated locally in numerous individual cells within a line or cluster of storms. The duration of straight‐line winds at a given location can be as brief as 30 seconds or can last upwards of 30 minutes. The storms producing the extreme winds may cover just 30 miles, or they may track for hours and cover hundreds of miles. The latter case represents an important class of extreme thunderstorm winds called “derechos.” A Derecho is an extreme, widespread, and long‐lived windstorm, usually associated with bands of rapidly moving showers or thunderstorms variously known as bow echoes, squall lines, or quasi‐linear convective systems. If the swath of wind damage extends for more than 240 miles, includes wind gusts of at least 58 mph along most of its length, and several, well‐separated 75 mph or greater gusts, then the event may be classified as a derecho. In general, derechos follow two basic types: Progressive Derechos tend to form on the northern edge of a steamy air mass, and the derecho is usually associated with one primary, very intense thunderstorm cell that follows the boundary of the hot air. These derechos have the greatest potential for catastrophic damage, and given enough instability, there is almost no limit to the intensity of their thunderstorm winds. Serial Derechos, by contrast, tend to form to the west of warm and unstable air masses, often along cold fronts, and often in the presence of very fast winds aloft. These instances lead to long, arcing, fast‐moving lines of storms with many different cells, any of which can harness the strong winds aloft and produce damaging winds. These derechos can produce widespread damage because of all the “candidate” storm cells, but they generally lack the destructive potential of progressive derechos. Hennepin County has been affected by numerous extreme straight‐line windstorms, including derechos. Every decade from the 1950s through the 2010s had multiple extreme thunderstorm wind events within 258 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 82 the county. 4.3.3.2. Range of magnitude Maximum wind speeds: ● Hennepin: ○ Measured 100 mph, Wold‐Chamberlain Field (MSP), July 20, 1951 ○ Measured 86 mph at Flying Cloud Airport, on 15 July 1980 ○ Estimated over 100 mph on July 3, 1983 ● Other Twin Cities Metro: ○ 110 mph sustained, gust 180 mph, St. Paul, Aug 20, 1904 ● Minnesota: ○ 121 mph, Donaldson, MN, September 1, 2011 ○ 117 mph, Alexandria, July 19, 1983 ● Region: ○ 128 mph (Northeast of Madison, WI May 31, 1998) ○ 126 mph, Atkins, IA, August 10, 2020 (140 mph estimated from damage surveys) Maximum width: 100 miles (Kansas – The “Super Derecho of May 8, 2009) Longest track: 1300 miles (The Boundary Waters‐Canadian Derecho July 4‐5, 1999) Longest duration: 22 hours (The Boundary Waters‐Canadian Derecho July 4‐5, 1999) Costliest US Derecho: $7.5 Billion (The Iowa‐Midwest Derecho of August 10, 2020) Deadliest US Derecho: 73 killed (The “More Trees Down” Derecho July 4‐5, 1980) 4.3.3.3. Spectrum of Consequences B2b Extreme thunderstorm winds and derechos are most common in the warm season and pose risks to those involved in outdoor activities. Campers or hikers in forested areas are vulnerable to being injured or killed by falling trees. Boaters risk injury or drowning from storm winds and high waves that can overturn boats. Trees around lakes pose risks to walkers, joggers, and cyclists. At outside events such as fairs and festivals, people may be killed or injured by collapsing tents and flying debris. Additionally, anyone caught outside may be injured by flying debris. Any person without adequate shelter is at significant risk in extreme thunderstorm winds. Occupants of cars and trucks also are vulnerable to being hit by falling trees and utility poles. Further, high profile vehicles such as semi‐trailer trucks, buses, and sport utility vehicles may be blown over. Even those indoors may be at risk for death or injury during derechos. Mobile homes may be overturned or destroyed, while barns and similar buildings can collapse. People inside homes, businesses, and schools are sometimes victims of falling trees and branches that crash through walls and roofs; they also may be injured by flying glass from broken windows. Finally, structural damage to the building itself (for example, removal of a roof) could pose danger to those within. Throughout Hennepin County, and especially in suburban and urban areas, electrical lines are vulnerable to high winds and falling trees. In addition to posing a direct hazard to anyone caught below the falling lines, wind damage to the power infrastructure can result in massive, long‐lasting power outages. 259 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 83 Hundreds of thousands of people may lose power for a week or more, as happened most recently in 2013. In addition, unlike the localized damage produced by a tornado, often covering the equivalent of one square mile, extreme thunderstorm wind damage can be widespread, affecting tens or even hundreds of square miles within the county. As a result, repairs often require substantial effort, with additional delays related to shortages in supplies. Extreme straight‐line winds also can expose socio‐economic vulnerabilities among Hennepin County’s diverse and growing population. Derechos and severe thunderstorms can strike quickly, posing serious challenges to the elderly, or anyone with limited mobility who is caught outside. Those new to the region who are unfamiliar with severe weather, how to access information about it, and how to respond, may be caught off‐guard and unprepared for the dangerous winds. Language barriers also may prevent some people from getting vital information as the storm is approaching. Anyone without adequate shelter will be subject to all the risks of being outside during dangerous thunderstorm winds. In general, extreme thunderstorm winds pose greater threats to disadvantaged populations that may lack the resources others have to anticipate, plan for, seek shelter from, and recover from extreme straight‐line winds. 4.3.3.4. Potential for cascading effects Flash Flooding ‐ On occasion, the convective system responsible extreme wind damage will stall, back‐build, or regenerate, producing excessive rainfall. In other cases, the storm may simply unload enormous quantities of rainfall. On July 1, 1997, a complex of thunderstorms produced 80‐110 mph winds and extensive damage from Wright into western Hennepin County, while dropping 3‐5 inches of rain in 60‐90 minutes over much of the area. The rains flooded every type of road in the county, submerging vehicles and significantly delaying emergency vehicles deployed to respond to the extreme wind event. Power Outages and Arctic Outbreaks – Dangerously cold air had never been considered a serious concern in relation to extreme thunderstorm winds and derechos, which tend to form during the warm season. On December 15, 2021, however, a historic outbreak of intense thunderstorm winds and tornadoes struck southeastern Minnesota, knocking out power for 1‐3 days as temperatures in the 10s F settled into the region. Any extreme straight‐line wind occurring outside the usual warm season, and particularly between November and March, may pose significant cold weather risks in its aftermath. Without power, electrical baseboard heat will not operate, nor will many appliances, security systems, electronic devices, or lights. 260 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 84 Power Outages and Intense Heat – Some of the most intense summer thunderstorm winds and the explosive class of “progressive derechos” tend to occur on the fringes of major heat waves. The heat and deep moisture often pool near the boundary that promotes the development of thunderstorms, and those ingredients act to fuel the intensification of the storms and the development of destructive winds. When thunderstorm winds damage the electrical infrastructure during or prior to intense heat waves, residents are left without the benefit of air‐conditioning while having to deal with intense heat. This sort of cascading effect occurred in the Ohio Valley and eastern US on June 29, 2012, when a derecho traveled for 700 miles, impacting 10 states and Washington, D.C. An estimated 4 million customers lost power for up to a week. The region impacted by the derecho was also during a heat wave, which claimed 34 lives in areas without power following the derecho. Wildland Fires – Extreme straight‐line winds and derechos can obliterate millions of trees across miles of forest due to the extreme winds associated with them. This increases fuel loads on forests and escalates the risk of wildland fire. Tornadoes – Extreme straight‐line winds and tornadoes can and do occur with the same convective system at times. In addition to the December 15, 2021, event discussed above, damaging straight‐line winds and tornadoes also occurred near each other in or close to Hennepin County on July 3, 1983, July 1, 1997, and September 21, 2005. The tornadoes may occur with isolated supercells ahead of the derecho producing squall line, or they may develop from storms within the squall line itself. Tornadoes have occurred with serial derechos, as on December 15, 2021, and on May 12, 2022, in southwestern Minnesota, and they have also occurred with progressive derechos, as on July 3, 1983. Blizzards – It has yet to be documented in Minnesota, but any cold‐season derecho is likely to be associated with a vigorous low‐pressure system and it would be possible for not just cold air, but intense snow and wind, to follow damaging thunderstorms within 6 to 48 hours. This map illustrates the large‐scale meteorological environment favorable for progressive and serial derechos on the northern or western fringe of a high‐ pressure area associated with a major heat wave over central and eastern United States. 261 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 85 4.3.3.5. Geographic Scope of Hazard B1c Hennepin County is within a high‐frequency corridor for extreme thunderstorm winds and derechos that covers much of the eastern half of the US. Every part of the county has experienced significant damage from unusually intense thunderstorm winds. Within the county, there are no favored areas. Winds estimated to 80 mph hit downtown Minneapolis in April of 1986, tearing a hole in the roof of the Metrodome. Winds at least that strong winds have hit every corner of the county, with 100 mph winds measured at the international airport in 1951, and winds likely well over 100 mph striking the northern suburbs in July of 1983. Nationally, derechos most commonly occur along two axes. One track parallels the "Corn Belt" from the upper Mississippi Valley southeast into the Ohio Valley; the other extends from the southern Plains northeast into the mid‐Mississippi Valley. During the cool season (September through April), derechos are relatively infrequent but are most likely to occur from east Texas into the southeastern states. Although derechos are rare west of the Great Plains, derechos occasionally do occur over interior portions of the western United States, especially during spring and early summer. The highest annual frequencies of occurrence appear along the "Corn Belt," from Minnesota and Iowa into western Pennsylvania, and in the south‐central states, from eastern parts of the southern Plains into the lower Mississippi Valley. However, the frequencies vary by season. During the warm season (May through August), derecho events are most frequent in the western part of the Corn Belt. During the remainder of the year (September through April), the maximum frequencies shift south into the lower Mississippi Valley 4.3.3.6. Chronologic patterns (seasons, cycles, rhythm) Extreme straight‐line winds and derechos in the United States are most common in the late spring and summer (May through August), with more than 75% occurring between April and August. The seasonal variation of derechos corresponds rather closely with the incidence of thunderstorms. However, as noted above, Minnesota (and neighboring states) experienced extreme straight‐line winds qualifying as a derecho on December 15, 2021. Approximate number of times "moderate and high intensity" (MH) derechos affected points in the United States during the years 1980 through 2001. Areas affected by 3 or more derecho events are shaded in yellow, orange, and red. 262 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 86 4.3.3.7. Historical data/previous occurrence B1d The Independence Day Derecho of 1977 Although it did not affect Hennepin County, the “Independence Day Derecho of 1977” formed over west central Minnesota on the morning of Monday, July 4th. As the derecho moved east‐southeast, it became very intense over central Minnesota around midday. From that time through the afternoon, the derecho produced winds of 80 to more than 100 mph, with areas of extreme damage from central Minnesota into northern Wisconsin. The derecho continued rapidly southeast across parts of Lower Michigan during the evening, producing winds up to 70 mph and considerable damage before finally weakening over northern Ohio around 1:30 AM on Tuesday, July 5th. This event was notable for affecting recreationist and travelers out enjoying the Independence Day holiday. West Metro to Northern Wisconsin Derecho of 1983 On July 3, 1983, between 12:30 and 13:20 local time, a complex of extremely severe thunderstorms affected a southwest to northeast swath of Hennepin County. Damage was most extensive from eastern Lake Minnetonka, through Maple Grove and Champlin. The storms continued into Anoka County and produced the Twin Cities area’s most recent EF‐4 tornado in Andover (most recent as of January 2024). Extreme straight‐line winds caused significant damage in a southwest‐to‐northeast swath across Hennepin County. The storm complex raced northeastward into Wisconsin during the next few hours, and aerial surveys conducted by the University of Chicago found over 150 linear miles of continuous EF‐1‐equivalent straight‐line wind damage, with pockets of EF‐2 damage—stretching from Carver County to Ashland, Wisconsin. The National Weather Service Issued “Very Severe Thunderstorm Warnings” for the storm, to indicate winds in excess of 75 mph, and sirens sounded throughout Hennepin County. This storm remains (as of 2024) the most destructive severe convective storm event in the Twin Cities Metropolitan Area, since the May 6, 1965, tornado outbreak. 263 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 87 The I‐94 Derecho of 1983 Around dawn on the morning of Tuesday, July 19, 1983, well north of warm/stationary front over South Dakota and northern Iowa, a bow echo moved out of northeast Montana and began producing damaging winds in northwest North Dakota. This would be the beginning of a noteworthy progressive derecho event that would move across the northern Great Plains and upper Mississippi Valley and reach the Chicago metropolitan area by late evening. As the convective system's cold pool continued to deepen and elongate east‐southeastward with the mean cloud‐layer flow, it ultimately reached the warm front as that boundary advanced slowly north across eastern South Dakota and southern Minnesota. This meeting occurred during the early afternoon over west central Minnesota, and likely accounts for the appreciable increase in storm strength observed around that time as the convection became surface based. At this time the storm system also expanded in scale, evolving into a squall line with two and sometimes three bow echo segments as it continued across Minnesota and later Wisconsin, with Interstate 94 near its central axis. Winds over 100 mph were recorded at the airport in Alexandria, Minnesota, Minnesota, where planes and hangers were damaged and destroyed. The storm continued to produce much damage as it moved east‐southeast across south central and southeast Minnesota; approximately 250,000 customers lost electrical power in the Minneapolis/St. Paul area, a record at that time. Thirty‐four people were injured in Minnesota and Wisconsin from this storm. Of these injuries, 12 were from mobile homes being blown over, and eight were from falling trees. The Northwoods/ “Right Turn” Derecho of 1995 During the late afternoon of Wednesday, July 12, 1995, thunderstorms formed over southeast Montana and began producing winds that damaged homes and barns. As the storm system moved east across North Dakota, vehicles were overturned, and a grain bin was destroyed. Measured winds reached 70 mph at Bismarck, ND. As the system approached Fargo during the early morning of July 13th, it became a well‐ defined bow echo storm with measured winds of 91 mph at the Fargo airport. The The path of the 1983 I‐94 Derecho as it crossed over six states on July 19, 1983. The path of the “Right Turn” Derecho of 1995. One of three derechos to occur on consecutive days across Northern Minnesota. 264 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 88 derecho was becoming a "high end" event. The derecho took a track similar to one of the previous nights, producing significant damage for the second night in a row from southeast North Dakota eastward across northern Minnesota to western Lake Superior. Damage was extreme across Minnesota, with over five million trees blown down and many buildings damaged, and some destroyed. Six campers were injured from the falling trees during the pre‐dawn hours. Trucks with plows were needed to clear many of the roads, and some areas were without power for a week. Damage totaled well over $30 million in 1995 dollars. Extreme Thunderstorm Winds and Other Hazards, July 1, 1997 A complex of very intense thunderstorms moved out of South Dakota during the afternoon and approached the Twin Cities during the early evening, producing multiple tornadoes rated up to F‐ 3 (now EF‐3), along with destructive winds that spread from central Minnesota into Wright, Sherburne, Hennepin, and Anoka counties and beyond. Although not long enough to qualify as a derecho, this storm was as destructive over a path that was over 100 miles long and 10 miles wide in some areas. Wind gusts estimated from 85 to 110 mph damaged small airports and planes; destroyed homes and garages; snapped or uprooted tens of thousands of trees; flipped trailers and mobile homes; blew down headstones in cemeteries; and produced over 100,000 power outages in the western and northern Twin Cities area, including Hennepin County. The storms also produced extreme rainfall rates, exceeding the threshold for 200 or even 500‐ years storms at the 1 and 2‐hour duration, as 3‐5 inches of rain occurred in 60‐90 minutes. The rains overwhelmed drainage capacity across Hennepin County and stranded or submerged vehicles on parts of Interstates 94, 394, 494, 694, 35‐W, along with parts of US Highways 10, 169, and 212, and literally dozens of other state, county, and smaller roads. The intense flash‐flooding hampered emergency responses in the parts of the county damaged by winds. Hail Derecho, May 15, 1998 A severe squall line developed in western Texas around midnight and raced northeastward, making it to south‐central Kansas by daybreak, southwestern Iowa by mid‐morning, and the Twin Cities area by 16:00 local time. The storms produced widespread damaging wind along the 1000‐ mile‐long track, and reached peak intensity in Iowa, Minnesota, and Wisconsin, with fast‐moving tornadoes and 1‐2” hail driven by 60‐80 mph winds. This was an unusual extreme wind event, qualifying easily as a derecho, but not fitting easily into the “progressive” or “serial” categories. This is among the only known damaging thunderstorm events in Minnesota history to have originated in Texas. 265 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 89 The storms produced a record number of power outages in Minnesota (the record has since been broken twice), and snapped or uprooted thousands of trees in Hennepin County alone (with estimates of over 1000 trees killed in Ramsey County). A tornado tracked from Roseville into Blaine, at an estimated speed of 80 mph, causing significant damage to homes. The majority of the damages, however, were from wind‐ driven hail, which broke windows, damaged roofs, bent garage doors, and forced automobile dealerships in Bloomington to submit claims for their entire outdoor inventories. The compound hail and wind damage from this storm produced over a billion dollars, adjusted for inflation, in home, automobile, and business property insurance claims. The largest hail reported in the Twin Cities was 2 inches, and most reports were in the 1‐1.5” range. However, the intense straight‐line winds turned the hail into dangerous projectiles, and produced far more damage than would normally be expected. The Southern Great Lakes Derecho of 1998 During the early evening of Saturday, May 30, tornado‐producing supercells over eastern South Dakota merged and became a squall line that moved east into southern Minnesota. As the squall line crossed southern Minnesota it evolved into a bow echo system that expanded in scale and raced east across the southern Great Lakes before finally dissipating over central New York after sunrise on Sunday, May 31st. This bow echo system produced one of the most dangerous and costly derecho events in the history of the Great Lakes region. The "Southern Great Lakes Derecho of 1998" adversely affected millions of people on the weekend after Memorial Day. Many casualties and record amounts of damage occurred. Radar at 16:25 local, as bowing hail core entered central Twin Cities on May 15, 1998 The Southern Great Lakes Derecho as it moved over Hennepin County On Saturday, May 30th. 266 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 90 The bow echo system began to produce significant wind damage over south‐central Minnesota about 10 p.m. Saturday evening. As the system moved rapidly eastward it grew south into northern Iowa and caused damaging winds over most of southeast Minnesota and northeast Iowa. Many trees and power lines were blown down and several farm buildings were damaged or destroyed. The most intense damage occurred near the northern end of the bow echo system in Minnesota, from Sibley and McLeod Counties eastward across southern portions of the Minneapolis/St. Paul metropolitan area. Along this band, winds greater than 80 mph were measured; in some areas, estimated speeds reached 100 mph. Tens of thousands of trees were blown down, 500,000 customers lost power, two semi‐trailer trucks were overturned, two apartment building roofs were blown off, and 100 boats were destroyed. In addition, over 100 homes were destroyed or badly damaged, and over 2000 others received some damage. Twenty‐two people were injured, and damage to property was estimated to be about $48 million in 1998 U.S. dollars...with $35 million dollars of that damage occurring in Dakota County alone. In summary, while crossing southern Minnesota and northeastern Iowa, the derecho event caused about $50 million in 1998 U.S. dollars of damage, left about 600,000 customers without power, and injured twenty‐two people. In some areas, power was not restored until nearly a week after the event. Boundary Waters – Canadian Derecho On July 4, 1991, a major derecho in the BWCAW, known as the Boundary Waters‐Canadian Derecho, lasted for more than 22 hours, traveled more than 1,300 miles, and produced wind speeds averaging nearly 60 mph, peaking at 80‐100 mph. The blowdown caused widespread devastation with casualties both in Canada and the United States. The storm front initiated as large complex of thunderstorms in South Dakota. The storm moved west to east snapping tree trunks in half that pulled power lines down with them in Cass, Crow Wing, Itasca and Aitkin Counties. After blowing down trees on 1,300 acres on the Chippewa National Forest and dropping heavy rains that eroded 9,000 acres of shorelines, the storm continued into northeast Minnesota. The storm entered the Arrowhead region of northeastern Minnesota in the early afternoon. Here, winds of 80 to 100 mph resulted in injuries to about 60 canoe campers and damage to tens of millions of trees within 477,000 acres of forest land on the Superior National Forest in the course of leveling a swath 30 miles long and 4 to 12 miles wide. The storm affected approximately 477,000 acres (16 percent of the Superior National Forest). The BWCAW sustained the heaviest damage in a line from Ely to the end of the Gunflint Trail. Figure 2. Percentage of trees blown down in Superior National Forest in northeast Minnesota on July 4, 1999. Scale: 1" = 15 miles. (Courtesy of USDA Forest Service, Superior National Forest) 267 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 91 Other Notable or Recent Extreme Thunderstorm Wind Events o September 21, 2005 (Hennepin County)—Large, slow‐moving supercell thunderstorms produced large hail, tornadoes, and extreme downburst winds in Anoka and northern Hennepin County, with wind gusts estimated up 100 mph in Brooklyn Center, where a man was killed by falling trees. o September 20, 2018 (southern Minnesota)—A line of fast‐moving thunderstorms, like a serial derecho but not traveling far enough to qualify, produced nearly continuous and severe damage as tornadoes and straight‐line winds ravaged communities in south‐ central and southeastern Minnesota, including Waseca, Owatonna, Faribault, Northfield, and Cannon Falls. National Weather Service surveys indicated straight‐line winds exceed 100 mph. o July 19 (central Minnesota and July 20, 2019 (southern Minnesota)—An intense heat wave with Heat Index values to 115° F fueled a derecho that tracked 490 miles from central Minnesota into Michigan. The next day, as the heat dome settled southward, another derecho tracked 860 miles from western South Dakota, through southern Minnesota, Wisconsin, and northern lower Michigan, crossing the damage path of the previous day’s extreme winds in Wisconsin. o August 10, 2020 (Iowa and Midwest) – One of the most extensive and destructive mainland storm events in US history, an extreme derecho tracked from the Iowa/Nebraska border to the Indiana/Ohio border, reaching maximum intensity in eastern Iowa, where winds gusted over 100 mph over an unusually large area, with 80‐ 120 mph gusts lasting over 30 minutes in areas near Cedar Rapids. o December 15, 2021 (Southeast Minnesota and Midwest) – By far the latest‐in‐the‐ season severe weather outbreak in Minnesota, this serial derecho traveled from southern Nebraska into Wisconsin, producing widespread 75 mph winds and 22 tornadoes across south‐central and southeastern Minnesota, damaging buildings and homes, uprooting trees, and knocking out power. One man near Rochester was killed by straight‐line winds. This event set a record back to 2004 for most reports of hurricane‐force (74 mph) wind gusts. The storms were followed quickly by a strong cold front the dropped temperatures into the 20s and 10s F, as extreme non‐convective winds associated with a powerful low‐ pressure area spread over the region. o May 12, 2022 (Corn Belt into western Minnesota)– Another powerful serial derecho with wind gusts of 85 to over 100 mph required just six hours to track from southern Nebraska to the Brainerd Lakes area of Minnesota. This massive event produced a dust storm from the dry conditions in western and central Minnesota, along with extensive damage to towns and rural properties. As of October 2023, this event was estimated to have produced over three billion dollars in damage across the region. 4.3.3.8. Future trends/likelihood of occurrence B1e For decades, the science was inconclusive about the connection between climate change and extreme thunderstorm winds or derechos, suggesting and trends in the frequency or intensity of these dangerous hazards would be short‐lived and attributable primarily to “normal” variations in weather and climate patterns. Recent research, however, has suggested that a warming climate can influence the size and/or intensity of derechos and other extreme thunderstorm wind events. Physical modelling simulations of the August 268 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 92 2020 derecho in Iowa revealed that while the storm would not necessarily have produced stronger winds in a warmer world, the likelihood of a stronger nearby heat wave would have allowed the damaging winds to cover more area and last longer. Another investigation of extreme straight‐line wind occurrences showed an observed increase both their intensity and their areal coverage in the United States as the climate has warmed and theorized a 7.5% increase in intensity for each additional degree C (1.8 degrees F) of warming. Similarly, a study of a lethal 2022 Mediterranean derecho showed that the marine heat wave in its vicinity that helped fuel it was itself made substantially more likely and more intense by rising global temperatures. This marine heatwave contributed substantial intensity and wind energy to the thunderstorm complex, which simulations showed would have been of “ordinary” strength in the absence of climate change. Taken together, these studies suggest that the changing climate can make extreme straight‐line thunderstorm winds and derechos larger, longer lasting, and in some cases, more intense. As the climate continues warming, therefore, a given extreme straight‐line wind event may be more likely to affect Hennepin County and neighboring areas. 4.3.3.9. Indications and Forecasting National responsibility for developing tornado indications and forecasts rests with the National Weather Service’s Storm Prediction Center (SPC) in Norman, Oklahoma, and the local National Weather Service office in Chanhassen. 4.3.3.10. Critical Values & Thresholds Winds in a derecho must meet the National Weather Service criterion for severe wind gusts (greater than 57 mph) at most points along the derecho path. Most other extreme straight‐line wind events are well above this threshold as well. In stronger derechos, winds may exceed 100 mph. Based on current warning criteria and analysis of local and regional storm events, the following thresholds apply: 58+ mph: Entry level for “severe.” Some damage to trees and powerlines. 70+ mph: outdoor warning sirens activated in Hennepin County; significant tree and electrical infrastructure damage, with structural damage possible. 80+ mph: Wireless Emergency Alerts (WEAs) triggered; structural and vehicular damage likely; risks from airborne debris. 100+ mph: tornado‐like damage expected, with secondary damage from debris‐bombardment. 4.3.3.11. Preparedness Hennepin County Emergency Management employs meteorologists who monitor the potential for extreme straight‐line winds and communicate with an array of county personnel as conditions warrant. Those planning to be outdoors for a significant length of time must be aware of the weather forecasts, especially if well‐removed from sturdy shelter. Preparation means staying "connected" via television, radio, NOAA Weather Radio, or social media. Extreme straight‐line winds rarely occur without warning, 269 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 93 although warning lead times may be comparatively limited during the early stages of storm development. Emergency water and food supplies, can openers, batteries, and flashlights should be on‐hand in case of power disruptions. 4.3.3.12. Mitigation Education and Awareness Programs Educating homeowners on the benefits of wind retrofits such as shutters and hurricane clips. Ensuring that school officials are aware of the best area of refuge in school buildings. Educating design professionals to include wind mitigation during building design. Structural Mitigation Projects – Public Buildings & Critical Facilities Anchoring roof‐mounted heating, ventilation, and air conditioner units Purchase backup generators Upgrading and maintaining existing lightning protection systems to prevent roof cover damage. Converting traffic lights to mast arms. Structural Mitigation Projects – Residential Reinforcing garage doors Inspecting and retrofitting roofs to adequate standards to provide wind resistance. Retrofitting with load‐path connectors to strengthen the structural frames. 4.3.3.13. Recovery Recovery from extreme straight‐line winds can take weeks as power outages from these storms can be extensive. A widespread event, or one in densely populated areas, may require search‐and‐rescue operations, which can be hampered when fallen trees or downed power lines block critical routes. Utility and infrastructure repair needs can exceed local resources and staff availability. Homes and businesses often require extensive repairs, bottlenecking the supply of contractors who provide such work, and opening the door to out‐of‐state and even predatory contract services who exploit the desperation and confusion often associated with disaster recovery.

Hazard Assessment: HAIL 4.3.4.1. Definition Hail is precipitation that is formed when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the thunderstorm where they are continuously lofted and form into hail. They eventually become heavy and fall to the ground. Hail can cause billions of dollars of damage to structures, cars, aircraft, and crops, and can be deadly to livestock and people. Damaging hail is associated with severe thunderstorms, and is often found in proximity to strong winds, torrential rainfall, and even tornadoes. Supercell thunderstorms are responsible for most Minnesota hail reports more than 1.5 inches in diameter, and nearly all reports in excess of 2.5 inches. These supercell thunderstorms may or may not be tornadic at the time of hail production. Damage becomes significantly more likely as hail size increases because the impact factor increases exponentially with incremental growth (Table 4.3.4A). Table 4.3.4A Hail diameter and impact. From Marshall et al. (2001). Hail Diameter 1” 2” 3” Impact (foot‐lbs) <1 22 120 4.3.4.2.

Costliest hail event ● May 15, 1998: $950 million USD in 1998 dollars (~3.1 billion in 2023) from damages in Minnesota resulting from hail, straight‐line winds, and isolated tornadoes. Vast majority of losses were from wind‐driven hail, which destroyed thousands of new and used vehicles, roofs and siding on thousands of homes. 4.3.4.3. Spectrum of consequences B2b Ultimately, the thunderstorm strength governs the size of hailstones and dictates the amount of time a given area will be exposed to them. Hail falling in small “popcorn” thunder‐ storms that form with weak instability and low shear tends to be short‐lived and sub severe (less than 1” diameter), although in rare instances can be up to golf ball‐sized (1.75”). Hail in fast‐ moving squall‐lines tends to be short‐lived and similar in size, although intense winds may turn the hail into dangerous and damaging projectiles. In large and/or slow‐ moving supercell thunderstorms, hail can fall for up to 30 minutes at a given location, and the high instability and shear producing these storms also often yields golf ball‐or‐larger hail stones. Although somewhat rare, regenerating supercell thunderstorms may produce multiple hailfalls over a given location during a single event. Hail over one inch in diameter may produce small “dimples” or “pocks” on vehicle exteriors. At 1.5 inches, damage to roofing materials becomes common. At sizes greater than 2”, windshields and rear windows are often cracked or shattered, vehicle bodies damaged badly, residential windows may be broken, residential siding welted, and many varieties of roofs badly damaged (Table 4.3.4B) for an example of roof damage thresholds). Although fatalities are uncommon, injuries to the head, shoulders, back, and arms are not. Severe bruising, often in multiple locations, is the most typical type of injury. Drivers and passengers of vehicles also may have cuts and lacerations from flying glass. Significant mobile home damage from hail. Source: NSSL 273 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 97 Table 4.3.4B. Damage onset thresholds for various roofing materials. From Marshall et al. (2002). Large hailstorms also tend to halt traffic and may require snow removal equipment to clear area roads. An early morning hail event in November of 1999 caused traffic jams and spinouts in Eden Prairie, and snowplows were needed to clear over 2 inches of accumulated hailstones from I‐494. ‘ Although the human toll from hail tends to be much lower than from tornadoes and straight‐line winds, hailstorms are often costlier, because of the costs associated with cosmetic damages to residences, vehicles, and businesses. Severe crop damage is also common, with soybeans and corn especially susceptible to damages from wind‐blown hail. Hail rarely causes infrastructural damage. 4.3.4.4. Potential for cascading effects The consequences of hail are generally limited to the duration of the hail event, providing few options for cascading effects. However, large, and damaging hail events tend to be associated with strong or severe thunderstorms that produce or can produce other convective weather hazards, which can exacerbate or compound the impacts. The large hail core in a tornado‐producing supercell thunderstorm is often very near the tornado itself. Thus, hail damage victims are at risk of becoming tornado victims as well. High situational awareness is therefore required during large hail. Any person caught outside during a hailstorm is also at significant risk from excessive rainfall and lightning. Any building or vehicle with shattered windows is also more susceptible to flying debris through those now open windows as well. 274 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 98 4.3.4.5. Geographic scope of hazard B1c Minnesota is north and east of the spatial hail frequency maximum within the US, which stretches from southwestern South Dakota, into Nebraska, Kansas, Oklahoma, Colorado, and Texas. Within Minnesota, hail tends to be most common in the southern and western portions of the state, although large and damaging hail has been observed in every county. The map of all known 4” hail reports since 1955 does show a preference for western and southern Minnesota, but also shows a clustering of reports near the Twin Cities, where more people are available to observe and report hail. 4.3.4.6. Chronologic patterns (seasons, cycles, rhythm) Most years, Hennepin County sees at least one large hail event. The seasonal hail threat coincides with the thunderstorm season, generally from April through September, with a notable peak in frequency in June and July. Severe hail has been reported as early as March in Hennepin County, and as early as February in greater Minnesota. Hail was observed with thunderstorms in the Twin Cities on December 16, 2015, though no damage was observed. Damaging hail in Hennepin County has been reported in November and has occurred several times during October.

Historical (statistical) data/previous occurrence May 6, 1965: Most widespread, intense, and long‐lasting hail event on record in Twin Cities. Although May 6, 1965, is best known for its devastating tornadoes in the Twin Cities, the storms also produced destructive hail for an unusually long duration and over an unusually large area. Hail the size of ping pong balls, golf balls, tennis balls and baseballs were reported throughout the evening, in association with both the tornadic storms and the many non‐tornadic thunderstorms cells. The largest hail stones were reported in Hennepin County, generally inside what is now the 494‐ 694 corridor. Hail reports were received before the first tornado confirmations, and well after even the last suspected tornado, and the hail event lasted approximately six hours. Many areas were hit by tornadoes early in the evening, and destructive hail later in the evening, and some locations were hit by three distinct waves of hail larger than golf balls. Locations in Hennepin County reporting golf ball or larger hail include Minneapolis, Bloomington, St. Louis Park, New Hope, Brooklyn Center, Maple Grove, Brooklyn Park, Edina, Deephaven, Crystal, and Eden Prairie. May 15, 1998: Derecho hailstorm A severe squall line developed in western Texas around midnight and raced northeastward, making it to south‐ central Kansas by daybreak, southwestern Iowa by mid‐ morning, and the Twin Cities area by 16:00 local time. The storms produced widespread damaging wind along the 1000‐mile‐long track, and reached peak intensity in Iowa, Minnesota, and Wisconsin, with fast‐moving tornadoes and 1‐2” hail driven by 60‐80 mph winds. The storms produced a record number of power outages in Minnesota (the record has since been broken twice), and snapped or uprooted hundreds of trees in Hennepin County alone (with estimates of over 1000 trees killed in Ramsey County). A tornado tracked from Roseville into Blaine, at an estimated speed of 80 mph, causing significant damage to homes. Most of the damages, however, were from the hail, which broke windows, damaged roofs, bent garage doors, and forced automobile dealerships in Bloomington to submit claims for their entire outdoor inventories. Wind (blue), hail (green), and tornadoes (red) reported on May 15, 1998. Generated from Severe Plot 3.0 (see references). Radar at 16:25 local, as bowing hail core entered central Twin Cities 276 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 100 The largest hail reported in the Twin Cities was 2 inches, and most reports were in the 1‐1.5” range. However, the intense straight‐line winds turned the hail into dangerous projectiles, and produced far more damage than would normally be expected. August 6, 2013: The National Night Out Storm On an evening when many Minnesotans were outside at neighborhood block parties, a powerful supercell thunderstorm moved across central Minnesota into western Wisconsin, producing a large swath of severe weather. Most reports were concentrated just south of the I‐94 corridor, and the storm caused extensive damage to crops and vehicles. The National Night Out storm had less wind but somewhat larger hail than the May 15, 1998, storm. Winds were generally confined to 65 mph or less, but hail sizes were typically 1.5 ‐ 2 inches in the core of the storm, which covered the southwestern third of Hennepin County. Damage to roofs and vehicles was common from Maple Plain, through the Lake Minnetonka area, into Eden Prairie and Bloomington. Damages were not quantified locally, but Aon‐ Benfield counted $1.25 billion in damages from storms over the northern and central US on August 5‐7, noting that Minnesota and Wisconsin were hardest‐hit.

Image courtesy Eden Prairie Police Department 277 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 101 An additional significant hail event occurred on August 11, 2023. However, that incident did not have as high of impacts as the other events already described. 4.3.4.8. Future trends/likelihood of occurrence B1e Research into hail frequencies in a changing climate has been somewhat limited, though modelling efforts have suggested that the frequency of hail may decrease at the expense of more days with straight‐line winds, because the atmosphere may favor higher instability but lower‐shear profiles as the equator‐to‐ pole temperature gradients weaken (Brooks 2013). Other research has suggested there may be fewer hail days, but more significant events on the days with hail. The bottom line is that significant hailstorms, some significant, are still to be expected into the future. 4.3.4.9. Indications and Forecasting Like other severe weather hazards, national responsibility for hail monitoring and forecasting lies with the National Weather Service’s Storm Prediction Center (SPC) in Norman, Oklahoma. The SPC uses three different “products” that detail in anticipation of a severe weather event: Convective Outlooks are spatial products that assign risk categories for severe weather and quantify the varying risk for hail (and other hazards) each day, along with an explanation of the basis for the risk categories assigned. Outlooks are issued for Day 1 (day of), and days 2‐8. Only Day‐1 outlooks contain hail‐specific probabilities. “Day 1” outlooks are issued at 01:00, 08:00, 11:30, 15:00 and 20:00 (all times CDT). For Day 1, risk categories include Marginal, Slight, Enhanced, Moderate, and High. These risk categories are assigned based on the probabilities of severe weather (or a particular hazard) occurring with 25 miles of a point. (As shown in Table 4.3.4C) 278 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 102 Table 4.3.4C Risk categories and probabilities are displayed on maps as color contours. The image below shows the slight risk and probabilities of specific hazards at the 15:00 CDT outlook, just hours ahead of the National Night Out storm. SPC probabilistic risk table with corresponding outlook categories 279 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 103 Mesoscale Discussions (MDs) are used to identify a particular area of concern within a risk area, often when storms have developed or are expected to, and to communicate the possibility that a watch may be issued. The MD will be tagged with a statement of likelihood regarding the issuance of a Watch, as follows: Severe Potential…Watch Unlikely (5 or 20%) Severe Potential…Watch Possible (40 or 60%) Severe Potential…Watch likely (80 or 95%) Severe Potential…Watch Needed Soon (95%) MDs can also be used to communicate additional concerns or trends during an ongoing event. Like Convective Outlooks, MDs are both graphical and textual. The following MD graphic was issued after the 15:00 CDT Convective Outlook, in anticipation of a watch issuance. Convective outlook (upper left), tornado (upper right), severe wind (lower left), and hail probabilities on august 6, 2013. From SPC’s severe weather events database. 280 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 104 Watches are issued when atmospheric conditions are favorable for the development of severe weather. They are more geographically specific than Convective Outlooks, and they have defined geographic boundaries, as well as start and end times. Typically, a watch will cover about 50,000 square miles‐‐slightly more than half the size of Minnesota‐‐and will last between 5 and 8 hours. Tornado watches are used when conditions favor development of tornadoes, in addition to other forms of severe weather. Severe thunderstorm watches are used when the tornado risk is relatively low and hail or strong winds are expected. Large hail can be expected with both types of watches, and neither connotes a greater or lesser risk of hail. The National Night Out hail even was initially covered by a Tornado Watch, which was replaced by a Severe Thunderstorm Watch after a few hours, when it became apparent there was not enough low‐level moisture or shear to produce tornadoes, but plenty instability aloft and mid‐level shear to produce large hail and strong winds. Below is the Severe Thunderstorm Watch outline with radar overlay. Mesoscale Discussion graphic issued in anticipation of National Night Out severe weather event 281 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 105 In addition to the SPC’s information and products, the local National Weather Service Forecast Office issues a Hazardous Weather Outlook (HWO), generally 1‐2 times per day, as situations warrant, to share thoughts about the potential for severe weather, including hail. These outlooks often discuss likely timing and locations. 4.3.4.10. Detection & Warning Local responsibility for detecting and warning citizens about severe hail lies with the National Weather Service forecast office in Chanhassen. The primary means to communicate urgent storm location and timing information is with Severe Thunderstorm and Tornado Warnings. These warnings indicate that severe weather is imminent and will be affecting the warned area for a specified period of time. As with watches, hail can be expected in both Severe Thunderstorm and Tornado Warnings, and neither is a better indicator than the other of hail risk. The NWS uses a combination of trained spotters and radar to detect severe hail. NWS Chanhassen has a RADAR site for remote monitoring of hail‐containing storms‐‐the NEXRAD WSR‐88D in Chanhassen. Numerous tools and algorithms enable NWS staff in Chanhassen to use this system for identification of severe hail in thunderstorms. Severe thunderstorm Watch outline with radar overlay on August 6, 2013 282 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 106 Spotter reports, reports from emergency managers, and increasingly, reports from social media also help forecasters in Chanhassen assess the severity of ongoing storms. 4.3.4.11. Critical values and thresholds The National Weather Service considers hail to be severe if it equals or exceeds one inch in diameter. The NWS will issue a severe thunderstorm warning with a “Considerable” tag when hail is expected to be 1.75 inch in diameter or greater or will issue a severe thunderstorm warning with a “Destructive” tag when hail is expected to be 2.75 inches in diameter or greater which would trigger a Wireless Emergency Alert for those in the warning area. Because impact increases exponentially with incremental increases in hail size, larger hailstones pose a significantly greater risk to safety and property. Therefore, spotters are trained to use common objects to make estimates about the size of hailstones. It should be noted that few hailstones are ever measured. Instead, they are often observed, compared to the common objects, and then the size is inferred from the size of the stated objects. Thus, reported hail sizes are almost always crude estimates. Table 4.3.4D summarizes the common objects used as hail size references, along with the approximate diameter. The diameters, and often not the common objects, will be preserved in the Storm Events Database. 4.3.4.12. Prevention Hailstorms cannot at present be prevented and should be considered an occasional risk within Hennepin County. 4.3.4.13. Mitigation The risks of being killed or injured by hail are greatest when hail is very large and/or wind driven. Thus, awareness of conditions that could lead to severe weather and hail, and having a plan of retreat if storms approach is of primary importance. As with all storms, the safest place to be when it’s hailing is inside, in a sturdy structure, away from windows. Even though cars often lose windows and contain some flying glass, they may be safer than being outside, if the travel distance to the vehicle is reasonable. If no shelter or vehicle is available, retreat to lower ground, if possible, stay away from trees, which pose a lightning risk, and by covering the head to avoid potentially lethal impacts from large hail. Hailstone size comparisons of commonly reported reference objects. Table 4.3.4D 283 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 107 On the road, many drivers make choices that ultimately compromise the safety of other motorists. Driving into hail at highway speeds increases a hailstone’s momentum (and therefore impact) substantially. Thus, if it begins hailing while driving, slow down and look for potential shelter options off the road. There may be none, but slowing down will reduce the impact of hail to the vehicle, reducing the risk for damage, and potential injury from shattered glass. If slowing down does not adequately reduce the risks, pull completely off the road, never under an overpass, and stop. 4.3.4.14.

Hazard Assessment: LIGHTNING 4.3.5.1. Definition Lightning is one of the oldest observed natural phenomena on earth. It has been seen in volcanic eruptions, extremely intense forest fires, surface nuclear detonations, heavy snowstorms, in large hurricanes, and most commonly, thunderstorms. Lightning is essentially an electrical current where electrostatic discharges between the cloud and the ground, other clouds, within a cloud, or with the air. Within a thunderstorm, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. Those collisions create an electric charge. The positive charges, or protons, form at the top of the cloud and the negative charges, or electrons, form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The ground’s electrical charge concentrates around anything that sticks up, such as metal conductors, tall buildings, people, or trees. The positive charge coming up from these points eventually connects with the negative charge reaching down from the clouds, and that is when you see the lightning strike. 4.3.5.2. Range of Magnitude The magnitude of lightning is incredibly variable from storm to storm. Typically, when discussing magnitude of lighting, one is concerned mostly with lighting strikes that hit the ground. GRAPHICS 4.3.5A and 4.3.5B are using data from the National Climatic Data Center, which show the reported costs from lightning for the past 10 years.

Spectrum of Consequences B2b Lightning strikes are the leading causes of wildfires and have been responsible in the past for some of the most devastating fires in the southwest United States. According to Storm Data, Minnesota ranks 28th in the United States in lightning deaths from 1959‐2012. Lightning is not only a threat to public safety, but also a threat for public and private structures because of the large number of structural fires started from lightning each year. Lightning can have direct and/or indirect effect, depending on whether it strikes a structure directly or not. The effects depend greatly on the conductivity of the materials the electricity travels through. Material Consequence Electrical Electrical voltages created by electrical discharges dissipated in the ground that is struck by lightning. Thermal Substantial damage and injuries from fires, burns, and destruction caused by a major release of heat. Electrodynamic Forces of attraction occur between parallel conductors that are traversed by currents in the same direction create mechanical stresses and strain. Electromagnetic The lightning current induces extremely high voltage and an extremely strong electromagnetic field that generate very powerful electric pulses that can damage sensitive electronic devices. Electrochemical Corrosion due to currents circulating through buried conductors Acoustic (Thunder and Windowpanes can be shattered a few meters from the point of impact. 0 0.5 1 1.5 2 2.5 3 3.5 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014Million $Total Damage Cost from Lightning Per Year: Minnesota 10 Year Average = 1.21 287 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 111 Pressure Waves) Physiological From simple dazzling to being struck dead by lightning, with a range of effects in between: Nervous shocks, various forms of blindness, deafness, blacking out, and momentary or prolonged comas. A common misconception of people being killed from lightning is because they were struck. Most lightning injuries and deaths are causes by mechanisms other than direct lightning strikes. Only 3‐5% of lightning strike victims take a direct strike. 3‐5% of lightning victims are contact injuries where the person is touching or holding an object to which lightning attaches, such as indoor wired telephones or plumbing that transmits current to the person. 30‐35% of injuries are caused by a side flash, also called splash. Side flashes occur when lightning hits an object such as tree or building and travels partly down that object before a portion jump to a nearby victim. Most injury (50‐55%) come from ground current. Ground current arises because the earth is not a perfect conductor. Ground current effects are more likely to be temporary, slight, and less likely to produce fatalities. However multiple victims and injuries are more frequent from ground current. Another 10‐15% of injury occur from upward leaders. Upward leaders are upward discharges of lightning, which almost always occur from towers, tall buildings, or mountain tops. A direct consequence to the body is an intense shock can severe impair most of the body’s vital functions. Cardiac arrest is common. Commonly when there is a strike that affects the heart directly, there is a massive shutdown. With every beat the heart depolarizes and changes its electrical signal. In addition, people can develop problems days, weeks, or months after being struck or being close to a lightning strike. 4.3.5.4. Potential for Cascading Effects Lightning strikes that hit the ground, called cloud to ground strikes, can have a vast array of consequences. One of the most common cascading events is when a lightning strike causes a fire to start, which can then spread to homes, or produce wildland fire. Another consequence would be if lightning strikes a transformer and people are without power for days, those people could be at risk for heat illnesses if hot and humid conditions persist. When lightning strikes a building, transients are generated on adjacent power, data, telephone and/or RF lines. As these transients pass through electronic equipment on their way to earth, they can cause both immediate damage and longer‐term component degradation. However, the problem goes far beyond a direct strike. Today our electronic systems are intrinsically connected to the outside world, not only by mains power cables, but also through data and telephone lines, RF feeders, etc. Transient over voltages from lightning activity up to 1 km away can destroy equipment inside a building, even when the building itself has not been struck. As transients can be induced onto any conductive cable‐overhead or underground, the power, data, telephone, or RF lines leaving a building to join the main network or even running between buildings can provide a way in for transients looking for a path to earth. Lightning simply striking the ground, or even cloud‐to‐cloud lightning, induces a transient overvoltage on those cables, allowing access directly into the electronic heart of that theoretically protected building. The following is a list of possible secondary consequences following a lightning event. Downtime and disruption Hardware damage 288 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 112 Software corruption Data loss Lost production 4.3.5.5. Geographic Scope of Hazard B1c As mentioned, lightning is one of the oldest observed natural phenomena on earth and has been seen in many different types of natural phenomena. This means lightning occurs across the world, including the United States, and of course, Minnesota. Individual lightning strikes are relatively small in geographic scope. However, when an area has a storm filled with lightning, or multiple storms filled with lightning, you can have a large geographic area being affected all at the same time. Graphic 4.3.5C shows Flash Density map from Vaisala which shows the flashes per square mile per year for the entire United States. Graphic 4.3.5C 4.3.5.6. Chronologic Patterns Lightning can happen any time of year, however it is more prominent with spring and summer months as this is when most of the convective weather occurs. 289 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 113 4.3.5.7. Historical Data B1d Lightning is a usual occurrence in thunderstorms across the State and Hennepin County each year. Every year, about four percent of Minnesota structural fires are caused by natural events, one can infer these natural events to be lightning related. The National Climatic Data Center states that there have been $700,000 dollars in damage and 6 injuries due to lightning strikes in Hennepin County since August of 1995. From 1959‐2014, Minnesota has had 64 lightning fatalities in the state. Historically, data shows us that leisure‐related activities are the greatest source of lightning fatalities. From a study that looked at lightning deaths from 2006 through 2013, fishing contributed to the most lightning deaths with 11% of all deaths. See GRAPHIC 4.3.5D for the top 11 activities that contributed most the lightning deaths during this period. This is consistent with a study that was published in 1999 that looked at lightning casualties and damages from 1959 to 1994 in the United States. There have been are no other lightning related incidents that are within the scope of this plan. 290 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 114 GRAPHIC 4.3.5D Lightning Fatalities 4.3.5.8. Future Trends B1e Some studies have shown changes in lightning associated with seasonal or year‐to‐year variations in temperature, but there have not been any reliable studies conducted to indicate future trends of occurrence until recently. A study looked at two variables, precipitation, and cloud buoyancy and how they might be a predictor of lightning (see more in the indications and forecasting section for predicting and forecasting lightning). The scientists found that on average, climate models predict a 12 percent rise in cloud‐to‐ground lightning strikes per temperature degree increase in the contiguous U.S. This is roughly a 50 percent increase by year 2100 if earth continues to see the expected seven‐degree Fahrenheit increase in temperature. While this is a step into looking into the future trends of lightning as our climate continues to change, less is known about the exact locations on where strikes will increase. 4.3.5.9. Indications and Forecasting “Lightning is caused by the charge separation within clouds, and to maximize separation, you have to lift more water vapor and heavy ice particles into the atmosphere” (Romps, 2014). It is known that the faster the updrafts, the more lighting, in addition, the more precipitation, the more lighting. How fast the updraft of the convective clouds is determined by the convective available potential energy (CAPE) which is measured by radiosondes, balloon‐borne instruments, released by each weather forecast office (WFO) 291 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 115 twice a day. CAPE is essentially how potentially explosive the atmosphere is. In essence, where forecasters see high CAPE values, and high‐water vapor content in the atmosphere is where expected lightning and thunderstorms are to occur. 4.3.5.10. Detection & Warning Currently, there are no official alert or warning products that are issued by the National Weather Service for just lightning. There are, however, certain programs that can be used that have lightning detection. One of the leading lightning detection companies across the United States is Vaisala. Vaisala’s Global Lightning Dataset was first launched in September 2009. However, currently there is no way to receive lightning detection data from Vaisala, or other detection sources, without a paid subscription to a specific service. There are also very few, if any, sources that will give you the distinction between cloud to ground lightning, intra‐cloud, and cloud to air lightning, partly because the science is just starting to understand how to detect the difference. Hennepin County has installed lightning sensors at select mesonet stations in the Hennepin West Mesonet network which detect lightning strikes within a 20‐mile radius. These sensors can provide some information on how close lightning is to cities in Hennepin County. 4.3.5.11. Critical Values and Thresholds Although there are not watches or warnings for lightning, by using the detection services that available, one can watch how lighting within a storm is changing. In general, if lightning activity is increasing within a storm, one can infer that the storm is strengthening. If lighting activity is decreasing, one can infer that the storm is weakening. 4.3.5.12. Prevention You cannot prevent lightning from occurring, but you can prevent some of the consequences by being aware of when thunderstorms are forecasted as well as being aware of the potential cascading consequences that can accompany the lightning. If a person sees lightning or hears thunder, they should go inside immediately. 4.3.5.13. Mitigation While there is no way to prevent lightning from happening, there are mitigation strategies to help protect from the effects of lightning. First is protecting critical facilities and equipment by installing protection devices such as lightning rods and grounding on communications infrastructure, electronic equipment, and other critical facilities. Another way to mitigate for lightning is through educational and awareness programs. Developing brochures to hand out at festivals, or with monthly water bills is one of the popular strategies. Additionally, teaching schoolchildren about the dangers of lightning and how to take safety precautions is another way to reach the parents at home as well. 4.3.5.14. Response Quick response when it comes to effects from lightning is crucial. When someone is struck or is affected by a near strike, ground current, first aid and CPR is crucial. However, CPR must continue for a long time because it takes a long time for the heart to beat again, the diaphragm to function, and even longer for the brain to reboot and control vital organ functions. People who go into cardiac arrest from lightning have a 75 percent mortality rate. Quick response is also needed when lighting causes a fire. 292 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 116 Whether it is a structure fire or grass/wildland fire, the more spread, the more damage. Please see the Wildland Fire section of this hazard assessment for more information about response. 4.3.5.15. Recovery Assessing the damage is the first part of the recovery process. People who are victims of a strike or near strike ay not ever fully recovery and may continue to have issues the rest of their lives. However, the faster the treatment they can get immediately, the faster recovery they will see. 4.3.5.16. References Holle, Ronald L. 2012.

Hazard Assessment: RAINFALL, EXTREME 4.3.6.1. Definition Extreme rainfall leads to flash flooding, infrastructural and property damage, and even loss of life. Although the definition varies by application, extreme rainfall events are generally understood to have rates that meet or exceed a given threshold, often tied to storage or drainage capacity. Virtually all extreme rainfall events in Minnesota are associated with thunderstorms. Short‐duration extreme events, in which an unusually large quantity of rain falls in a short amount of time (for example, 3 inches falling in one hour) are often associated with severe supercell thunderstorms, squall lines, and mesoscale convective systems. Long‐duration events more than six hours tend to occur in environments favorable for strong thunderstorms, but not favorable for sustained severe weather. In these situations, there is often a stationary boundary allowing regenerating thunderstorms to pass over the same locations, in a process known as “training.” In forecasting applications, extreme rainfall drives the issuance of National Weather Service flash‐flood products based on “flash‐flood guidance,” which is a changing, location‐dependent value that utilizes pre‐existing soil moisture and land cover conditions. Unsaturated soils and ample vegetation require higher precipitation rates to trigger flash‐flooding than saturated soils, denuded vegetation, or impervious surfaces. Extreme rainfall also is critical to hydrologic design of roads, trails, culverts, retention and detention ponds, dams, and other types of infrastructure. Engineers and planners design these facilities to withstand all but some small percentage of all heavy rainfall events. For instance, many non‐critical features like small roads and trails are designed to withstand a storm that has a 10% probability in any given year (also known as the 10‐year storm). More critical features will often be designed for 100‐year rainfall events‐‐those that have a 1% probability in any given year. NOAA Atlas 14 contains the most recent scientific estimates of rainfall amounts for durations from 5 minutes to 60 days, and with recurrence intervals of 1 through 500‐years.

Spectrum of consequences (damage scale, common impacts and disruptions, response needs) B2b The most dangerous result of extreme rainfall is flash flooding, which has numerous consequences, arises from a combination of factors, and is covered in greater depth as its own chapter within this assessment. Other severe hazards are not related to directly flooding. Following is a brief annotated list of common consequences resulting from extreme rainfall: ● Injury, drowning, death: those unable to get to higher ground, and those stuck in vehicles that either failed to navigate or are unaware of high water are at significant risk. Flooded roads, particularly at night, are especially dangerous. ● Infrastructure damage: roads, culverts, drainage basins, bridges, and even dams can succumb to the direct force of heavy flowing water, and to erosion from the ground below. Sewer and wastewater systems may overflow. ● Stalled, stranded, or damaged vehicles. Many vehicle batteries die in high water, causing vehicles to stall. Parked vehicles in low‐lying areas may also be inundated and stranded. Water frequently gets inside the vehicles, damaging the electronics and the interior. ● Structural failure: eroding soils from a heavy rain may undermine the structural integrity of houses and buildings, resulting in complete or partial collapse. ● Water damage. Water enters sub‐grade floors through small openings and in extreme events can accumulate to inches or even feet on the lowest levels, as municipal sewer systems exceed capacity and water backs up into residential lines. Electrical equipment becomes susceptible to damage, and interior materials may be compromised and may develop dangerous mold or mildew. ● Crop damage: it is common for major extreme rainfall events to damage agricultural fields, often wiping out an entire season’s worth of crops. ● Water quality: extreme rainfall washes high level of compounds into area waterways, which may exceed allowable contaminant thresholds for days or even weeks after a major event. ● Recreational loss: extreme rainfall events target the lowest areas first, meaning that lakes and rivers are susceptible to overflow. No‐wake laws impede water sports, and overflowing streams and rivers can produce dangerous conditions for canoeing and other human‐powered water 295 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 119 activities. Trails and paths near lakes and rivers are often flooded, preventing bicycling, jogging, and walking. Recreational departments will require extra labor hours to return recreational resources to proper working conditions. 4.3.6.4. Potential for cascading effects Most cascading effects associated with extreme rainfall are identical to those associated with flash‐ flooding and urban flooding. Extreme rainfall hazards can easily be compounded by other pre‐existing hazards, as well as hazards that develop after an event. In many cases, extreme rainfall‐‐especially of shorter durations‐‐occurs with severe supercell thunderstorms, squall lines, and mesoscale convective systems. Almost by definition, these systems are multi‐hazard events. Thus, straight‐line downburst winds, large hail, tornadoes, and frequent lightning are often associated with the same storms that produce extreme rainfall rates. Power may be out, which complicates efforts to remove water using sump pumps. This was the case in June of 2013, following a major wind event in the Twin Cities. The July 23‐24 super storm produced record‐setting and basement‐inundating rainfall from storms that also produced heavy damage from tornadoes. There were instances during the evening in which tornado warnings and Flash‐Flood warnings were in effect for the same area simultaneously. Seeking shelter in a basement posed flood‐related risks. Extreme rainfall also can play a role in tree mortality, and associated damages to public sidewalks, personal property, and electrical systems. On June 21, 2013, a major tree fall event that was also the largest weather‐related power outage in state history, resulted not just from the prolonged downburst winds, but also from intense rains that fell both earlier in the day, and during the storm. Though the winds were 50‐ 60 mph with some higher gusts for over 10 minutes in many places, they produced far more damage than would be expected at those speeds. The severity of tree damage likely resulted from the saturated soils, which provided less resistance than normal, allowing trees to become “loose” and eventually topple. Whether short or prolonged in duration, extreme rainfall is often associated with summerlike air masses. Thus, extreme rainfall may occur before, during, or after an extreme heat event. Similarly, extreme rainfall can occur during drought conditions, as was the case in 1987. Additional specific cases of high‐impact multi‐hazard extreme rainfall events will be outlined in the Historical (statistical) data/previous occurrence section. 4.3.6.5. Geographic scope of hazard B1c Extreme rainfall rates may cover between 50 and 1500 square miles at a time. After accounting for movement, the total area affected by rainfall more than 3 inches may cover thousands of square miles, with hundreds of square miles receiving over six inches of rain. In exceptionally rare cases, 6‐inch rainfall totals may cover an area greater than 1,000 square miles‐‐approximately the size of two Twin Cities area counties. The Minnesota State Climatology Office has documented 12 of these “mega” rainfall events in Minnesota since the mid‐1800s. These events are always associated with catastrophic damage and often loss of life. 296 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 120 4.3.6.6. Chronologic patterns (seasons, cycles, rhythm) Extreme rainfall has been observed from April through November, but peak probabilities are generally from June through August, and to a lesser extent, September. The frequency of 3 and 4‐inch rainfall peaks during July. Graphic of 2, 3, and 4‐inch daily rainfall totals in Minneapolis since 1871. Like other convective weather hazards, extreme rainfall goes through more and less active periods. Hennepin County has at times gone many years between major events. 2014, 2002, and 1997, on the other hand, are relatively recent examples of years with multiple extreme events in the county. 4.3.6.7. Historical (statistical) data/previous occurrence B1d NOAA Atlas 14 is the definitive source for extreme rainfall estimates and contains the most recent scientific estimates of rainfall amounts for durations from 5 minutes to 60 days, and with recurrence intervals of 1 through 500‐years. The following table is for a point selected in central Hennepin County. The top row contains recurrence intervals (or return periods), and the left column is storm durations. The value in bold where they intersect is the likely amount in inches expected for a storm of that duration, at that recurrence interval. The values in parentheses represent the 90% confidence range around the bold value Example: For 24‐hour rainfall at a 100‐year recurrence interval is estimated to be 7.34 inches, and is 90% likely to be between 5.55, and 9.65 inches. 297 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 121 TABLE 4.3.6A is derived from a statistical technique that utilizes data from multiple stations and is based on observations. TABLE 4.3.6A Precipitation frequency estimates for a point in central Hennepin County The 100‐year recurrence value for 24‐hour rainfall is the most frequently cited value, and indeed, many structure are designed for such an event. It is, however, important to note that shorter durations of excessive rainfall can also overwhelm systems, and many have therefore been designed for 1, 3, or 6‐hour thresholds. Structural, civil, and hydrological engineers can provide further information on exceedance thresholds used for infrastructure elements. Additionally, heavy rainfall over longer durations can overwhelm systems, even when exceptional hourly rainfall rates are lacking. Extreme rainfall, therefore, should be anticipated on a variety of timescales, and not just measured by daily or 24‐hour rainfall only. Radar estimates and automated rain gauges help forecasters understand rainfall quantities for shorter and longer durations, and noteworthy rainfall events of many duration‐ magnitude combinations have affected Hennepin County. 298 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 122 July 23‐24, 1987, Super Storm The heaviest rainfall ever officially recorded at a Twin Cities weather station fell between about 18:00 CDT on 23 July and about 02:00 CDT on 24 July 1987. During this eight‐hour interval, observers at the Twin Cities International airport station measured an even ten inches of rain (9.15 inches of which fell in a five‐hour period). In addition to the heavy rainfall, the 23‐24 July storm spawned an F3 tornado near Goose Lake in Hennepin County and produced extensive damage in Maple Grove and Brooklyn Park. Damage in other areas was extensive, largely the result of flooded homes and businesses, ruptured storm sewers, and washed out or inundated streets and highways. Two flood related deaths were reported, and property damage was estimated to be in excess of $30 million (1987 dollars). The 23‐24 July storms occurred along an outflow boundary that had separated extremely warm, moist air to the south and east and much cooler, drier air immediately to the north and west. The interaction of these air masses produced intense thunderstorms with extremely heavy rainfall over the southwestern portion of the Twin Cities on 20‐21 July 1987, two days prior to the 23‐24 July outbreak. Rainfall amounts during this event included 3.83 inches at the Twin Cities airport station, 9.75 inches near Shakopee and 7.83 inches at the neighboring community of Chaska. The 23‐24 and 20‐21 July storms, together with the rainfall produced by thunderstorms earlier and later in the month, brought unprecedented July rainfall to the Twin Cities area. The International airport station recorded 17.91 inches, approximately six times the July normal. An unofficial monthly total of 19.27 inches was recorded in west Bloomington. Ironically, July 1987's excessive rainfall came in the middle of a prolonged period of subnormal precipitation. Precipitation had been below normal for every month from October 1986 through June 1987 and, following about six weeks of wet weather in July‐August 1987, the drought returned. Extreme dryness prevailed during much of the ensuing year with a near record dry June and record warmth during the summer of 1988. July 1, 1997, Derecho and Flood An intense mesoscale system containing supercells and a fast‐moving squall line tore through the central and northern Twin Cities area during the evening, producing extensive wind damage and catastrophic flooding. Numerous tornadoes rated up to F3, were reported from the Willmar area, through Wright and Sherburne Counties. Non‐tornadic winds more than 100 mph knocked out power, severely damaged structures, and snapped and uprooted trees in Wright, Anoka, Sherburne, and northern Hennepin counties. As the storm complex moved into the central portions of the Twin Cities, it produced some of the heaviest one‐hour rainfall ever measured in Minnesota. 3‐4 inches fell within one hour over the central and eastern parts of Hennepin County, as well as adjacent portions of Ramsey and Anoka counties. I‐35 and I‐94 were closed south of downtown Minneapolis and standing water more than 10 feet in some areas prompted boat rescues in south Minneapolis and Richfield. Edison High School in northeast Minneapolis sustained major flood damage, and hundreds of homes and residential complexes were severely damaged by inundation. 299 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 123 Late May through June 2014 ‐ repeated/persistent heavy rainfall events A persistently wet pattern punctuated by numerous heavy rainfall events during June 2014 led to significant flooding and estimates of approximately $12 million in damage throughout Hennepin County. The greatest impacts tended to be focused near water bodies and low‐lying areas. Numerous stations in Minnesota reported record monthly rainfall for June. May 31‐ June 2: 2‐4 inches of rainfall was common over the county, with 4.3” reported at Flying Cloud. This was part of a nearly statewide heavy rainfall event. Lake Minnetonka rose to its highest levels in 109 years following this event. June 6‐8: A scattered rainfall event, with up to 2 inches in western Hennepin County, and an isolated 3‐inch report near Independence. June 14‐16: 2‐3 inches throughout the county. Levels began rising rapidly along many waterways. June 18: Isolated reports of up to 1 inch in association with a major event concentrated over southern MN, and in advance of the more significant event on the following day. June 19: Major, long‐duration intense rainfall event, with waves of heavy precipitation throughout the day. Flooding became common and widespread. 3‐5 inches were common throughout the county, with 4.13 reported at MSP—the heaviest daily total since October 2005. 5.47” was reported by CoCoRaHS in Eden Prairie. Seven‐day rainfall amounts of 4‐8 inches were common across the county, with even more to the south and west. Municipalities, school districts, and other public interests within Hennepin County reported losses and expenses more than $12 million USD (2014). The following list is not exhaustive, but rather representative of the scale and impact of damage from the excessive rainfall. Bloomington, $265‐270k: parkland damage; destruction of warming house Eden Prairie, $360‐370k: pipe ruptures damage to Duck Lake Trail, Eden Prairie Road, recreational trails, sewers, and banks of Riley Creek Golden Valley, $90‐95k: unspecified damages to roads, sewers, culverts Greenfield, $20‐25k: roads, sewers Hennepin County Sheriff's Office, $26k: water patrol docks and one boat damaged. Hopkins School District, $5k: washouts at High School, West Jr. High, Gatewood Elementary, and Eisenhower 300 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 124 Minneapolis Park Board, $6.8M: Mudslide behind Fairview‐Riverside affecting 100' x 250' slope and exposing facility oxygen tanks and require extensive re‐engineering and restoration. Minnehaha Creek Watershed District, $180k: Lake Minnetonka reached record high water mark of 931.11 feet, and Minnehaha creek exceeded 100‐year flow at Hiawatha (with 893 cu ft.). The entire creek watershed was severely impacted, as were many of the MCWD's capital projects. Minnetonka, $55k: unspecified damages to municipal property Minnetonka Independent School District, $NA: Destruction/failure of retaining wall at high school. Mound, $1M: unspecified damages to streets, culverts, sewers, parks, and infrastructure Orono, $150k: severe damage to Starkey Road and Balder Park Road Park Nicollet Methodist Hospital, $3.6M: Drainage system destroyed; sunken grade creating sinkhole risk; low‐lying electrical circuitry inundated and damaged, pumping, sandbagging and dewatering required; barriers construction. Richfield, $70‐75k: Power failure at sanitary lift station, damage to pumps, trails and paths inundated, littered with debris, and damaged. St. Louis Park, $50‐55k: severe damage on Louisiana Ave Wayzata, $70‐75k: city marina flooded and damaged; culverts damaged, requiring emergency repairs. August 18‐20, 2007 ‐ worst rainfall event on record in MN Perhaps the most extraordinary precipitation event in Minnesota's modern history shattered Minnesota’s 24‐hour rainfall record. The 15.10" total recorded at 8:00 AM on Sunday, August 19, 2007, near Hokah in Houston County is the largest 24‐hour rainfall total ever measured at an official National Weather Service observing station in Minnesota, breaking the old record of 10.84 inches by an astonishing 39%. The storm also obliterated the state’s “unofficial” rainfall record, when a non‐National Weather Service rainfall observer near La Crescent (Houston County) reported 17.21 inches for the 24‐hour period ending 7:00 AM, Sunday, August 19. This is the largest 24‐hour value in the Minnesota State Climatology Office database and broke the previous statewide non‐NWS observer record 12.75” by a margin of 35%. Both new records far exceeded expected totals, even for record‐breaking events, and are so large, a true return period estimation is virtually impossible. Rainfall totals for entire 3-day rainfall event in southern Minnesota in august of 2007. In most areas, 80-90% of the totals came within the first 24 hours of the event. 301 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 125 The rainfall was caused by a series of strong thunderstorms moving along a stalled frontal boundary for an unusually long time. The most intense precipitation rates occurred during the afternoon and evening hours of Saturday, August 18, and the early morning hours of Sunday, August 19. Over the course of the event, all or portions of 28 counties received at least four inches of rain. Six‐ inch totals were common across the region, and portions of southeastern Minnesota reported three‐day totals ranging from 8 to 20 inches. The heaviest rainfall reports came from Winona, Fillmore, and Houston counties, where 36‐hour totals exceeded 14 inches. The largest multi‐day rainfall total reported (through Monday, August 20) was 20.85 inches observed near the town of Houston in northern Houston County. The deluge produced flooding tied to seven fatalities. Major flood damage occurred in many southeastern Minnesota communities. Hundreds of homes and businesses were impacted. Reports of stream flooding, urban flooding, mudslides, and road closures were numerous throughout southern Minnesota. The combination of huge rainfall totals and a very large geographic extent, make this an extraordinary episode. The area receiving six or more inches during a 24‐hour period during this torrent encompassed thousands of square miles‐ the largest such area known to the Minnesota State Climatology Office. There have been no other incidents that are within the scope of this plan. Damaging mudslide near Hokah.

Future trends/likelihood of occurrence B1e The 2023 National Climate Assessment indicates that winter and spring precipitation is expected to increase, while summer and fall precipitation will be more variable (NCA5, 2023). By mid‐century (2041‐ 2070), the latest science suggests that rainfall events that would ranking in the top 2% for the period 1981‐2010, will become more common. Most of Minnesota can expect, on average, an additional day per year with these events, which amounts to an approximate doubling in frequency. 4.3.6.9. Indications and Forecasting The Chanhassen Office of the National Weather Service is the local authority for extreme rainfall monitoring and forecasting, and uses flash flood guidance, based on soil moisture and land cover conditions, to evaluate whether expected and/or ongoing heavy rainfall poses a significant flooding risk. Additionally, NOAA’s Weather Prediction Center (WPC) has a legacy of advanced hydro‐ meteorological monitoring and prediction and offers Excessive Rainfall Outlooks and Mesoscale Precipitation Discussions that are comparable to the severe weather products offered by the Storm Prediction Center. Unlike the Storm Prediction Center, however, the WPC does not issue Watches of any sort. Forecasters monitor and analyze numerical weather models and other predictive tools to ascertain potential extreme rainfall and associated flash flooding threats. The following sequence of products may then be used in an idealized situation, though it should be noted that extreme rainfall threats may appear of disappear at any step in this timeline: 4+ days out: Chanhassen NWS Office highlights threat for heavy or extreme rainfall and flash flooding potential in Hazardous Weather Outlook products. 1‐3 days out: WPC issues Excessive Rainfall Outlook, indicating Marginal, Slight, Moderate, or High Risk of excessive rainfall, according to the following probabilities: Additional days per year with upper 2% rainfall events by mid-century (2041-2071). Source, 2014 National Climate Assessment, Midwest Chapter. 303 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 127 Risk Category Probability of Rainfall Exceeding Flash Flood Guidance at a Point Marginal (MRGL) 2‐5% Slight (SLGT) 5‐10% Moderate (MDT) 10‐15% High (HIGH) >15% Current/valid Excessive Rainfall Outlooks can be found at: http://www.wpc.ncep.noaa.gov /qpf/ excess _rain.shtml Within 48 hours: Chanhassen NWS Office issues Flash Flood Watch, based on combination of expected precipitation and local Flash Flood Guidance values. → Important: In early spring 2018, the NWS will no longer use Flash Flood Watches, and will instead consolidate them into generic Flood Watches, as part of its Hazard Simplification process: https://www.weather.gov/news/170307‐hazard‐simplification Within 1‐6 hours: WPC issues Mesoscale Precipitation Discussion to highlight emerging flooding potential from expected, developing, or ongoing thunderstorm and rainfall activity. These discussions are only used for large areas of concern (generally the size of 25 or more Minnesota counties) and do not pertain to highly localized extreme events. Each discussion includes an annotated graphic indicating the area of concern, and a brief text discussion focused on the mesoscale features supporting the anticipated heavy rainfall. The potential for flash flooding within the area of concern will be highlighted by one of three headlines: FLASH FLOODING LIKELY High confidence exists that environmental conditions are favorable, or will become favorable, for heavy rainfall that will result in flash flooding. FLASH FLOODING POSSIBLE Environmental conditions are favorable, or will become favorable, for heavy rainfall, but there are questions about how the event will evolve and/or whether flash flooding will occur. FLASH FLOODING UNLIKELY High confidence exists that environmental conditions are unfavorable, or will become unfavorable, for heavy rainfall that will result in flash flooding. Once event has begun: Chanhassen NWS Office issues Flash Flood Warning, based on combination of precipitation received, further precipitation expected, soil conditions, and stream levels and flow. A Flash Flood Warning is issued when flash flooding is occurring or is imminent. These warnings differ from Severe 304 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 128 Thunderstorm and Tornado warnings, in that they are not issued in advance of the parent thunderstorm(s), but instead after the storm has begun, ideally in advance of the flash‐flooding itself. The behavior of approaching storms is erratic enough that pre‐storm lead time for flash‐flood warnings would lead to high false alarm rates. Flash Flood Warnings are issued as polygons that attempt to match the spatial extent of the true threat (as opposed to covering entire counties). Like Severe Thunderstorm warnings, they may cover slivers of counties, or multi‐county swaths. The warning period depends on the duration of the event itself, but Flash Flood Warnings may continue for several hours after the precipitation has subsided. 4.3.6.10. Detection & Warning The Chanhassen NWS Office and North Central River Forecast Center (adjoining the Chanhassen office) monitor local flood conditions using a combination of manual and remotely sensed information. Key warning detection and decision sources include but are not limited to: Radar‐estimated precipitation, which can be used in conjunction with flash flood guidance values to determine flood potential. Automated, real‐time stream gaging, which indicates the level and flow of critical streams. Real‐time, manual, or automated rainfall reports Radar and local meteorological trends, indicating potential for storms to continue and/or redevelop in or near affected areas. Reports from spotters, emergency managers, first responders, the media, and the public Images or videos shared via social media or other means. The Chanhassen NWS Office will issue a Flash Flood Warning if the forecasters determine that information from the above and other detection sources indicate that flash flooding is occurring or is imminent in each area. 4.3.6.11. Critical values and thresholds Unlike other weather hazards, Watch and Warning thresholds for flash floods vary with the pre‐existing meteorological conditions. Conditions with saturated soils and high or overtopped streams require substantially less precipitation to generate flash‐flooding than conditions with low soil moisture and low stream levels. Although some anticipated precipitation amounts may suggest to forecasters that flash flooding is possible, irrespective of soil conditions, the Watch and Warning thresholds are generally determined on a case‐by‐case basis, by considering the Flash Flood Guidance for the area(s) of concern. Flash Flood Guidance (FFG) values estimate the average amount of rainfall (in inches) for given a duration required to produce flash flooding in the indicated county or area. These values are based on a combination on current soil moisture conditions and land cover considerations, and therefore change in response to the local hydro‐climatic situation. Throughout much of Hennepin County, and especially in urban areas, less rainfall is required to produce flash flooding than in many neighboring areas, because of the county’s high concentration of impervious surfaces. 305 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 129 Current flash‐flood guidance for 1, 3, and 6‐hour rainfall can be found at: https://www.weather.gov/ncrfc/LMI_ROF_NFP_FlashFloodGuidance 4.3.6.12. Prevention To improve water management and protect the sewage system from damage, cities can revamp their underground pipe and drainage systems by separating rainwater from the sewage system. The separation enables the wastewater treatment plant to function properly, without it being overburdened by large quantities of storm water. Other more obvious methods are to keep sewer systems clean of clog up with waste, debris, sediment, tree roots and leaves. 4.3.6.13. Mitigation Areas that have been identified as flood prone areas can be turned into parks, or playgrounds, buildings and bridges can be lifted, floodwalls and levees, drainage systems, permeable pavement, soil amendments, and reducing impermeable surfaces. Reducing impervious surfaces could include the addition of green roofs, rain gardens, grass paver parking lots, or infiltration trenches. Other mitigation strategies include developing a floodplain management plan, form partnerships to support floodplain management, limit or restrict development in floodplain areas, adopt and enforce building codes and development standards, improve storm water management planning, adopt policies to reduce storm water runoff, and improve the flood risk assessment. 4.6.3.14. Response One of the most important things to be done during the initial response is to make sure that people are safe. If their homes have been damages and are unlivable, finding a place for them to stay is among one of the top priorities. Next is the access to places if roads are washed out or still underwater. One complicated factor with flood disasters, is sometimes you do not know how bad the damage is until the water recedes, which can take time and slow the response. Another important part of response is to make sure water supply is available as quick as possible if there has been any contamination. The role of Hennepin County Emergency Management is to coordinate resources that our municipalities may need to accomplish all response needs. 4.6.3.15. Recovery As mentioned in river flooding, recovery from floods can take weeks, to months, to years. Extreme rainfall/flooding is unlike quick onset disasters (e.g., tornadoes) where you can see the damage immediately, sometimes with excessive rainfall/flooding you must wait for the flood waters to recede to find out what damage there is to recover from. A lot of the time, the longer the water level stays too high, the more consequences are introduced that you must then recover from. 4.6.3.16.

Hazard Assessment: HEAT, EXTREME 4.3.7.1. Definition Conditions of extreme heat are defined as summertime temperatures that are substantially hotter and/or more humid than average for a location at that time of year. Humid or muggy conditions, which add to the discomfort of high temperatures, occur when an area of high atmospheric pressure traps hazy, damp air near the ground. Extremely dry and hot conditions can provoke dust storms and low visibility. Typically, when extreme heat conditions last for two days or longer, they are called heat waves. 4.3.7.2. Range of Magnitude The magnitude of extreme heat can vary greatly. You can have extreme heat events where you have shorter periods (3‐5 days) with much higher‐than‐normal temperatures, or you can have longer periods (2‐3 weeks) with temperatures only 5‐10 degrees higher than normal temperatures. Hottest Heat Wave on record MN: July 18, 2011 Longest Heat Wave on record MN: June 3‐10, 2021 Most Recent Heat Wave for Hennepin County: August 25th, 2013 Deadliest MN Heat Wave: August 4‐8, 2001; 5 fatalities 4.3.7.3. Spectrum of Consequences B2b Extreme heat can be just as deadly as other natural hazards by pushing the human body beyond its limits. Under normal conditions, the body’s internal thermostat produces perspiration that evaporates and cools the body. However, in extreme heat and high humidity, evaporation is slowed, and the body must work extra hard to maintain a normal temperature. Most heat disorders occur because the victim has been overexposed to heat or has over exercised for his or her age and physical condition. Effects can be seen through just a few people or by many depending on extent the temperatures rise above normal, or other hazards occurring simultaneously. People most at risk include elderly and very young persons, chronically ill patients, socially isolated people, urban residents, and people without access to air conditioning. There are different conditions, or disorders, related to extreme heat illnesses: heat stress, heat exhaustion, heat stroke, and hyperthermia. Heat stress is the perceived discomfort and physiological strain associated with exposure to hotter than normal environment, especially during physical activity. Heat exhaustion is a mild‐to‐moderate illness due to water or salt depletion resulting from exposure to extreme heat conditions or strenuous physical activity. Heat stroke is a severe illness resulting from exposure to environmental heat, or strenuous physical exercise during extreme heat conditions. Heat stroke is characterized by a human body core temperature greater than 104oF along with central nervous system abnormalities such are delirium, convulsions, or coma. Heatstroke can have a fast onset and poor survival rate. 308 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 132 4.3.7.4. Potential for Cascading Effects One complicating factor when discussing impacts of extreme heat, is extreme heat doesn’t necessarily immediately impact people when it sets in, instead it is when the periods of extreme heat last for days and weeks that it takes its toll on people. Additionally, when overnight air temperatures do not cool below 70 degrees F, it does not give people’s bodies a break from the heat. An additional complicating factor is when extreme heat conditions are paired with another hazard. For example, if severe thunderstorms affect an area and knock out power right before extreme heat sets in, you now have additional people exposed to extreme heat without working air conditioners. Extended durations of extreme heat can also exacerbate drought conditions and can also lead to excessive power consumption needs causing the potential for brown‐ and black‐outs, which would only make the exposure conditions worse. Extended periods of extreme heat also contribute to wildfire hazard through a process wherein natural materials, particularly sand and bare soil absorb solar radiation, holding the heat very near the surface, resulting in extremely high surface temperatures. The hot surface heats the overlying air, which rises, carrying the heat upward. The extremely hot surfaces generate strong updrafts, essentially creating local winds that dry surrounding vegetation, increase fuel temperatures, and intensify and spread wildfires. The dry vegetation, high fuel temperatures, and high winds increase the static electricity, increasing the potential for spontaneous combustion, particularly during prolonged periods of drought. Extreme heat temperatures can also force the closure of airports due to the lack of sufficient air density for take‐offs and landings. 4.3.7.5. Geographic Scope of Hazard B1c When this hazard happens, it can be as small as a local hazard, or countywide with areas of highest concern in the largest metropolitan areas because of the Urban Heat Island (UHI). Urban heat islands are large metropolitan urban areas that are warmer in temperature than surrounding rural areas because of pavement, blacktop, and buildings. The University of Minnesota conducted a study showing the Twin Cities metro area temperature differences in 2011. Graphic 4.3.7A illustrates measured temperature differences of up to 10 degrees just within Hennepin County. 309 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 133 Graphic 4.3.7A 4.3.7.6. Chronologic Patterns While the definition of extreme heat indicates an extended period where temperatures are above average high temperature, you typically see extreme heat as an issue during the summer months of May through September in Hennepin County. 4.3.7.7. Historical Occurrence B1d There have been several past instances of extreme heat in Hennepin County. The earliest records of extreme heat include the Dust Bowl of the 1930’s. The Dust Bowl years of 1930‐36 brought some of the hottest summers on record to the United States, especially across the Plains, Upper Midwest, and Great Lake States. For the Upper Mississippi River Valley, the first few weeks of July 1936 provided the hottest temperatures of that period, including many record highs. Two consecutive heat waves occurred in 1999. The first was on July 23‐25, 1999, when a massive upper ridge over the central U.S. enabled heat to build into Minnesota. Heat indices ranged from 95‐110 on the 23rd, 90‐105 on the 24th, and climaxed at 95‐116 on the 25th. One death resulted from the heat wave after a man fell asleep inside a closed vehicle on the 25th. The second heat wave of 1999 occur less than a week later for central and south‐central Minnesota. This heat wave lasted from July 29th, 1999, through July 30th, 1999. This heat wave was stronger with heat indices climbing to the 95‐114 range with lows in the 70s and dew points in the middle 60s to 70s which produced heat indices 70‐85 even in the morning hours. In 2001, there were another two heat waves, one that was from July 30 through August 1st, and a second from August 4th through August 8th. The July 30th‐August 1st heat wave is commonly known for the heat wave where Minnesota Vikings football player Corey Stringer collapsed on the football field around 310 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 134 midday on July 31 in Mankato and was taken to the hospital. Mr. Stringer died early on August 1st, 2001. The second heat wave of 2001 came just three days later and persisted for five days. This heat wave produced five fatalities all within Hennepin County. Hot weather and tropical‐like humidity pervaded the region, as virtually all stations registered highs in the 90s all five days. Minneapolis‐St. Paul (MSP) reached 98 or 99 three straight days (August 5‐7) when highs were 98, 99 and 98 respectively; the highs at MSP on August 6 and August 7 set records. A few noteworthy heat indexes, including the highest known value around Minnesota for each day, are: August 4 ‐ 110 at Morris (Stevens County), 107 at Redwood Falls (Redwood County), and 102 at MSP. August 5 ‐ 114 at Alexandria (Douglas County) and Morris (Stevens County), 110 at Maple Lake (Wright County) and Montevideo (Chippewa County), and 107 at Mankato (Blue Earth County) and at MSP. August 6 ‐ 118 at Rush City (Chisago County), 114 at Redwood Falls (Redwood County), 110 at Faribault (Rice County), and 109 at MSP. August 7 ‐ 117 at Morris (Stevens County), 116 at Redwood Falls (Redwood County), 109 at MSP, and 107 at Staples (Todd County). August 8 ‐ 102 at Little Falls (Morrison County) and Staples (Todd County), 100 at Appleton (Swift County), and 95 at MSP. Another heat wave occurred in 2005. High temperatures at Minneapolis‐St. Paul International Airport remained at or above 90 degrees for 9 consecutive days between July 9th and 17th. This extended period of hot weather set a record for the 3rd longest streak of at or above 90‐degree highs since 1891 in the Twin Cities. On July 12th, a laborer putting up a fence in Arden Hills in Ramsey County suffered severe heatstroke. He collapsed at the work site and was rushed to a local hospital. His body temperature reached 108.8 degrees, but miraculously he survived after receiving intensive medical attention. He awoke from a medically induced sedation 24 hours after falling ill and made a full recovery. Two heat waves occurred in 2011, one in June and one in July. The June heat wave occurred on June 7th, where it broke the all‐time true temperature record for the day at 103oF. This was the warmest day in the Twin Cities in almost 23 years, when July 31, 1988, had a high of 105 degrees. The second heat wave of 2011 occur in July as a large ridge of high pressure expanded across the Upper Midwest and allowed for a stagnant pattern, and eventually oppressive heat and humidity to develop. The heat wave broke records for temperature and dew point, and even heat indices across the region. Maximum heat index values of 115 to 125 were common. A record high minimum temperature was set on July 18th, when a low temperature of 80 degrees was recorded at Minneapolis ‐ St. Paul International Airport. The previous record was 78 degrees which was set in 1986. A record high minimum temperature was also set on July 20th, when a low temperature of 80 degrees was recorded. The previous record was 76 degrees which was set in 1901, 1935 and 1940. A total of 44 fans were treated at Target Field (32 treated in their first aid facilities and more than a dozen treated in their seats). The heatwave led to record power demand. Xcel Energy set a record with the highest one‐day peak demand ever of a little more than 9,500 megawatts on Monday, July 18th. The heat affected turkeys in southwest Minnesota, where 50,000 turkeys died due to heat related causes near Redwood Falls. In addition to the turkeys that died, several news articles had references to heat related deaths to livestock in southern and western Minnesota, but the articles were not specific for counties. The heat and humidity were also blamed for road buckling on I‐94 in Minneapolis. Two lanes of northbound I‐94 at Lowry Ave, and two lanes of eastbound I‐94 at 49th Ave, were closed because of buckling pavement. 311 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 135 The most recent heat wave occurred in 2013 specifically August 25th through August 27th. A large ridge of high pressure built across the central part of the United States during the last week of August. Heat and humidity increased across the Upper Midwest starting the weekend of August 25th and lasted until the latter part of the week with a string of 90+ afternoon temperatures, combined with dew points in the 70s, caused heat indices to rise above 100 degrees from Sunday, through Tuesday, August 27th. In the Twin Cities metro area, heat indices remained above 80 degrees overnight, and afternoon heat indices continued above 100 degrees through Thursday afternoon, August 29th. The Minnesota State Fair was going on during the time. 216 people required treatment at medical stations at the fair for heat related illnesses, 10 of whom were transported to local area hospitals. In addition, several record high temperatures were observed, and a dew point temperature of 77 degrees on August 27th at 3:00 PM tied the MSP high dew point temperature record set on August 27, 1990. It also tied the record for highest dew point ever during the State Fair (77 degrees ‐ August 28, 1955, and August 27, 1990). Minneapolis schools canceled all outdoor after‐school athletics practices during this period. The August 26th high of 96 degrees in the Twin Cities broke the 94‐degree record set in 1948. In Hennepin County, from the 25th through the 29th, there were 28 people who were treated for heat related illnesses, either as walk‐ins at emergency rooms, or transported by ambulance to hospitals. There have been no other incidents that are within the scope of this plan. 4.3.7.8. Future Trends B1e Numerous studies have documented that human‐induced climate change has increased the frequency and severity of heat waves across the globe. While natural variability continues to play a key role in extreme weather, climate change has shifted the odds and changed the natural limits, making heat waves more frequent and more intense. In an unchanging climate both new record highs and new record lows are set regularly, even while the total number of new records set each year may decrease as time goes on. Sixty years ago in the continental United States, the number of new record high temperatures recorded around the country each year was roughly equal to the number of new record lows. Over the past decade, however, the number of new record highs recorded each year has been twice the number of new record lows, a signature of a changing climate, and a clear example of its impact on extreme weather. 312 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 136 4.3.7.9. Indications and Forecasting Heatwaves are most common in summer when high pressure develops across an area. High pressure systems can be slow moving and persist over an area for a prolonged period such as days or weeks. Not all high‐pressure systems bring heat waves. However, high pressure that is combined with high temperatures and high dew points are those that bring the extreme heat events. Typically, with high pressure, you have clear skies, which allows strong solar inputs as well. There has been a study done in 313 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 137 which showed local evaporation also plays a role in causing high moisture values near the surface. 4.3.7.10. Detection & Warning The two crucial values for the National Weather Service issuing excessive heat products are described below in the definitions of advisory, watch, and warning criteria. Excessive Heat Advisory: The heat index will reach 95 °F for at least three hours one day. The forecast maximum Wet Bulb Globe Temperature will reach 85 for three hours one day. The heat index will reach 95 °F for two days in a row, along with an overnight low no cooler than 73 °F. Excessive Heat Watch: A possibility the heat index will reach 100 °F for one day and/ro the forecast maximum Wet Bulb Globe Temperature could reach 87 for one day, and/or the heat index could reach 100 °F for two days in a row, along with an overnight low no cooler than 73 °F. Excessive Heat Warning: Maximum heat index at MSP Airport reaches 100 °F or greater for at least 1 day. The forecast maximum Wet Bulb Globe Temperature will reach 87 for one day. The heat index will reach 100 °F for two days in a row, along with an overnight low no cooler than 73 °F. Advisory conditions for at least four consecutive days. 4.3.7.11. Critical Values and Thresholds The heat index is what gives us the critical values for indications and warnings. The Heat Index is sometimes referred to as the “apparent temperature”. The Heat Index, given in degrees Fahrenheit, is a measure of how hot it feels when relative humidity is added to the actual air temperature. Another measurement that is used to describe how the human body reacts to extreme heat is the Wet Bulb Globe Temperature (WBGT). This is different from the heat index because it factors in wind and solar radiation along with temperature and humidity. The WBGT parameter has been used by the military for heat safety since the 1950s as it is a better representation for individuals who are active in the heat, since wind and sun factor into how out body cools itself off. Many athletic associations including the sports of 314 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 138 running, football, tennis, and soccer have used the WBGT as well. The critical values used by the military can be seen below. 4.3.7.12. Mitigation There are many ways to mitigate for extreme heat events. Mitigating from the health effects of extreme heat can be having air conditioning, cities opening cooling centers, or adjusting work ours for those individuals who work primarily outside. There are some energy efficiency measures in houses and small commercial buildings can help to keep the indoor environment within comfortable temperature conditions without use of air conditioning during extreme heat events such as: roof deck insulation, wall insulation, high performance windows, and building orientation. Mitigation strategies that require coordination and construction include shading of buildings, asphalt and other dark surfaces with trees can reduce the UHI effect. Solar panels placed on canopies over parking lots and other paved surfaces can also shade and reduce the UHI effect. Direct shading of buildings also reduces heat in buildings in the event of power outages in an extreme heat event. However, tree planting requires adequate space, water, and maintenance, and the correct selection of trees. Another mitigation strategy is the management and restoration of parks in urban areas increases vegetated areas, which can help reduce heat island effects. Increasing recreational and riparian spaces in urbanized areas has many additional benefits including health benefits from air and water quality improvements. Additionally, there are pavements that have technologies to reduce heat island effects. The pavements reflect more solar energy, enhance water evaporation, are more porous, or have been otherwise modified to remain cooler than conventional pavements. 315 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 139 Education about extreme heat can also be a strategy. TABLE 4.3.7A White‐Newsome et al (2014) describe educational strategies in their four‐city study: TABLE 4.3.7A Four City Study 4.3.7.13. Response There are many things an individual can do to respond to extreme heat events. The following list is from the American Red Cross: Listen to a NOAA (National Oceanic and Atmospheric Administration) Weather Radio for critical updates from the National Weather Service (NWS). Never leave children or pets alone in enclosed vehicles. Stay hydrated by drinking plenty of fluids even if you do not feel thirsty. Avoid drinks with caffeine or alcohol. Eat small meals and eat more often. Avoid extreme temperature changes. City Recommendations Detroit Revisit framing of heat warnings Invest in full scale public relations campaign to educate residents on heat and health. Educate grade school students about climate change. Ensure that county summer campaign includes a heat health component. Develop messages that connect climate change to everyday life New York Identify strategies to prevent oversaturation of messaging (e.g., home‐based care providers have many health messages to deliver) Using focus groups, determine how and where to best promote cooling centers to a greater diversity of vulnerable persons. Make health messages that apply to everyone. Consider additional risk factors in messaging, such as obesity and risk aversion Philadelphia Revisit messaging about where to go (e.g., ride public transportation, cooling centers, mall) during heat waves. Educate people to participate in traditional cooling behaviors. Increase messaging to encourage buddy systems or checking on loved ones. Consider use of social media or partnerships with GenPhilly (http://www.genphilly.org) to remind younger generations to check on vulnerable family members Phoenix Create clearinghouse of projects and materials Develop ―check on your neighbor‖ programs or messaging. Work with Salvation Army on trainings for social service providers Improve collective definitions of heat wave. Partner with academics to better translate study findings 316 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 140 Wear loose‐fitting, lightweight, light‐colored clothing. Avoid dark colors because they absorb heat from the sun. Slow down, stay indoors, and avoid strenuous exercise during the hottest part of the day. Postpone outdoor games and activities. Use a buddy system when working in excessive heat. Take frequent breaks if you must work outdoors. Check on family, friends and neighbors who do not have air conditioning, who spend much of their time alone or who are more likely to be affected by the heat. Check on your animals frequently to ensure that they are not suffering from the heat. As an Emergency Management agency, opening cooling centers to the public, adjust cooling center and homeless shelter hours to account for those at need during non‐traditional open hours are all response strategies used. Many time neighborhood networks are also unofficially activated to check on their elderly and vulnerable populations. The City of Chicago stated that one of the biggest changes after the 1995 Chicago Heat Wave has been technology. Chicago now has implemented a 311‐center phone number to reach City Hall. Someone in another state with an elderly mother living alone in Chicago can call the 311‐center, and a well‐being check will be conducted by the appropriate agency. This allows the city to be more proactive that reactive when it comes to calls about extreme heat illnesses. 4.3.7.14. Recovery Like many other weather‐related disasters, recovery from an extreme heat event is not fast. As mentioned, consequences from extreme heat can begin to show after the extreme heat has subsided so checking on vulnerable populations as part of the response, also carries over to the recovery process. It’s important to acclimatize to changes in temperatures. So as the body has started to get used to extreme heat once the temperature drops back down can have effects as well. Giving the human body time to adjust to these shifts is important to remember for workers who may spend most of their day outside. 4.3.7.15. References Bernard, Susan M., and Michael A.

Hazard Assessment: DROUGHT 4.3.8.1. Definition A generalized definition of drought is a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the affected area. In easier to understand terms, a drought is a period of unusually persistent dry weather that persists long enough to cause serious problems such as crop damage and/or water supply shortages. If the drought is brief, it is known as a dry spell, or partial drought. A partial drought is usually defined as more that 14 days without appreciable precipitation, whereas a drought may last for years. Another type of drought is a flash drought, which is a “rapid onset or intensification of drought […] set in motion by lower‐than‐normal rates of precipitation, accompanied by abnormally high temperatures, winds, and radiation” (NIDIS, 2024). When a drought begins and ends is difficult to determine because rainfall data alone won't tell you if you are in a drought, how severe your drought may be, or how long you have been in drought. The most used drought definitions are based on meteorological, agricultural, hydrological, and socioeconomic effects: 1. Meteorological – A measure of departure of precipitation from normal. Due to climatic differences, what might be considered a drought in one location of the country may not be a drought in another location. 2. Agriculture – Refers to a situation where the amount of moisture in the soil no longer meets the needs of a particular crop. 3. Hydrological – Occurs when surface and subsurface water supplies are below normal. 4. Socioeconomic – Refers to the situation that occurs when physical water shortages begin to affect people. 4.3.8.2. Range of Magnitude The severity of the drought depends upon the degree of moisture deficiency, the duration, and the size of the affected area. The magnitude of a considered drought event corresponds to the cumulative water deficit over the drought period, and the average of the cumulative water deficit over the drought period’s mean intensity. Most Severe Drought: 1030‐1936 Dust Bowl or ‘Dirty Thirties’ Longest Drought: 1944‐1950s: Southwestern United States Costliest: Second to the Dust bowl that is estimated to have cost $1 billion in 1930’s money is the drought of 1989 and 1999. It is estimated the drought costs somewhere between $80 and $120 billion worth in damage. 320 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 144 4.3.8.3. Spectrum of Consequences B2b Drought impacts are wide‐reaching and may come in different forms, such as economic, environmental, and/or societal. A reduction of electric power generation and water quality deterioration are also potential effects. Drought conditions can also cause soil to compact, decreasing its ability to absorb water, making an area more susceptible to flash flooding and erosion. A drought may also increase the speed at which dead and fallen trees dry out and become more potent fuel sources for wildfires. An ongoing drought which severely inhibits natural plant growth cycles may impact critical wildlife habitats. Drought impacts increase with the length of a drought, as carry‐over supplies in reservoirs are depleted and water levels in groundwater basins decline. Impacts from drought can also be exacerbated because of dust settling on snow, which causes increased solar energy absorption. As a result, snowmelt takes place earlier in the season and runoff magnitudes increase. The impacts related to early runoff pose problems for many important sectors in Minnesota including agriculture, recreation, tourism, and municipal water supplies. Reservoirs may also be at capacity during these constrained runoff periods, causing spills to be necessary. Ideally, to avoid releases of water downstream, water is captured over a longer timeframe with gradual melting of snowpack. Alternatively, dust produced from the hardening and drying of bare soil can also be exposed as vegetative cover decreases due to extended periods of drought. Although droughts can be characterized as emergencies, they differ from other emergency events in that most natural disasters, such as floods or forest fires, occur relatively rapidly and afford little time for preparing for disaster response. Droughts typically occur slowly, over a multi‐year period, and it is not obvious or easy to quantify when a drought begins. 4.3.8.4. Potential for Cascading Effects As mentioned, there are many different consequences that can occur from drought. Since droughts typically occur over longer time periods of months, seasons, and years it’s possible to start with a few consequences initially, but as the drought persists or worsens, your consequences can start to multiply. This can happen within just the drought hazard itself, but another aspect is adding another hazard on top of or as result of the drought. For example, in drought conditions that have persisted for many months, if you have a rain event occur over a short period of time, the ground will not be able to absorb the moisture quick enough creating a flash flood event. Another common cascading event is the threat and increase of wildfires due to the dry conditions. 4.3.8.5. Geographic Scope of Hazard B1c Due to natural variations in climate and precipitation, it is rare for all of Minnesota to be deficient in moisture at the same level at the same time. However, single season droughts, and different magnitudes and intensity over some portions of the State are quite common. In addition, it is typical for all of Hennepin County to be within a drought at the same time, although possible to have part of Hennepin County in a higher level of drought category than another part of the county. 4.3.8.6. Chronologic Patterns Drought can occur any time of year, however people mostly think of its effects in the spring and summer months. The onset of summer drought intensity can, and typically, begins with the prior fall and winter 321 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 145 being drier than average. 4.3.8.7. Historical Data B1d Perhaps the most devastating weather driven event in American History, the drought of the 1920’s and 1930’s significantly impacted Minnesota’s economic, social, and natural landscapes. Abnormally dry and hot growing season weather throughout the better part of two decades turned Minnesota farm fields to dust and small lakes into muddy ponds. The parched soil was easily taken up by strong winds, often turning day into night. The drought peaked with the heat of the summer of 1936, setting many high temperature records that still stand today. One of the most significant droughts to affect the County was the drought of 1976‐1977. The 1976‐77 drought was widespread and by some measures was exceeded only by the severity of conditions during the 1930’s. In spring of 1976, the general lack of precipitation was statewide. Shallow residential and farm wells began to go dry in June. Some municipalities also were affected. Precipitation continued to be much less than normal for the rest of 1976 and gradually returned to normal during the summer of 1977. Minnesota’s State Climatology Office records show the precipitation total for the Twin Cities to be 16.50 inches, well below the 27‐inch average (based on the Twin Cities Monthly & Yearly Twin Cities Total Average). Another severe drought that had an impact on Hennepin County was the drought of 1988. A nationwide event, the Drought of 1988 intensified in June with Minneapolis receiving only 0.22 inches of rain, making it the driest June ever recorded in the metro area. The June average temperature for Minneapolis was 74.4 degrees Fahrenheit, which equaled the second warmest June ever. Statewide temperatures ranged from 6 to 9 degrees above normal. By the end of June most of the state was classified as either in “severe” or “extreme” drought. The drought continued into July with temperatures six degrees above normal in Minneapolis and rainfall 1.5 to 3 inches below normal. Soil moisture levels reached record lows at most University of Minnesota Experiment Stations. In the Minneapolis area, maximum temperatures of 90 degrees or greater were recorded 17 days, a record high for July. Most locations reported maximum temperatures exceeding 100 degrees at least once during the month. By August, the drought began to subside but not after severe agricultural damage was caused and several records were broken across Hennepin County and the State of Minnesota including: June precipitation averaged 1.40 inches statewide, replacing the old record low of 1.50 inches set in 1910. May through August average temperature at 69.7 degrees was nearly 2 degrees higher than the old record set in 1936. Minneapolis‐St. Paul Airport had 44 days with 90 degrees or more. The old record has been 36 days in 1936. The Palmer Drought Index dropped below ‐7 in northwest Minnesota for the first time since record keeping began at the turn‐‐ of‐the‐century. The old record had been ‐6 in September 1934. Groundwater levels throughout the state reached new record low levels. The Mississippi River at St. Paul reached low levels previously experienced only in 1934 and 1976, prompting the first total sprinkling ban in Minneapolis and St. Paul. 322 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 146 There have been no other incidents that are within the scope of this plan. 4.3.8.8. Future Trends B1e In the past few years, there have been several studies published that show to have conflicting conclusions when it comes to trends in past drought occurrence and how the future looks. Part of this is because of the different definitions of drought. Because of the different definitions, a small reduction in the mean of one parameter, can translate into a much larger increase in drought on the other parameters, or definitions. Many of the computer modeling have shown increased trends in drought occurrences across much of the northern hemisphere. However, results of satellite‐based studies along with other observation‐based studies conclude there is no significant trend in areas with drought in the past three decades. 4.3.8.9. Indications and Forecasting Drought intensity categories are based on five key indicators and numerous supplementary indicators. The accompanying drought severity classification table shows the ranges for each indicator for each dryness level. Because the ranges of the various indicators often don't coincide, the final drought category tends to be based on what most of the indicators show. The analysts producing the final determined category also weighs the indices according to how well they perform in various parts of the country and at different times of the year. 323 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 147 Range Category Description Possible Impacts Palmer Drought Index CPC Soil Moisture Model (Percentiles) USGS Weekly Streamflow (Percentiles) Standardized Precipitation Index (SPI) Objective Short and Long‐term Drought Indicator Blends (Percentiles) D0 Abnormally Dry Going into drought: short‐term dryness slowing planting, growth of crops or pastures.

Detection & Warning At present, the best approach for predicting the development, intensification, and demise of a drought is a two‐fold strategy that combines the monitoring of both local water and climate conditions and large‐ scale wind patterns, including the comparison of current conditions to historical analogues, with the 324 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 148 interpretation of computer forecasts. This strategy is employed by both the monthly and seasonal drought outlooks, which are issued monthly by the National Oceanic and Atmospheric Administration, National Weather Service, and Climate Prediction Center as an operational effort geared toward infusing such advances into drought predictability. Although predicting drought on any scale remains a challenge, progress in understanding global‐to‐regional scale climate‐system phenomena provides hope for improving drought prediction at longer lead times. Early warning of drought onset, and characterization of its evolving environmental and economic impacts, can be further enhanced using regional‐scale early warning systems that promote sustained partnership networks linking meteorological and climatological information providers to water, agriculture, and other private and public management communities. 4.3.8.11. Critical Values and Thresholds According to the Minnesota Statewide Drought Plan, there are five drought phases/triggers that follow closely to the drought intensity categories. TABLE 4.3.8A describes the drought triggers from the Minnesota Drought Plan. These triggers are based on conditions for the different watersheds across the state. TABLE 4.3.8A Drought Triggers Drought Phase/Triggers Conditions Non‐Drought Phase A signification portion of the watershed is not under drought conditions according to the U.S. Drought Monitor. Drought Watch Phase A significant portion of the watershed is “abnormally Dry” or in a “moderate Drought”. Drought Warning Phase A significant portion of the watershed is in a “Severe Drought”, or from public water suppliers using the Mississippi River, the average daily flow at the USGS gage near Anoka is at or below 2000 cfs for five consecutive days. Restrictive Phase A significant portion of the watershed is in an “Extreme Drought”, or for public water suppliers using the Mississippi River, the average daily flow at the USGS gage near Anoka is at or below 1500 cfs for five consecutive days. Emergency Phase A significant portion of the watershed is in an “Exceptional Drought”, or highest priority water supply needs are not met, or there are threatened or actual electricity shortages due to cooling water supply shortages, or for public water suppliers in the Twin Cities, the average daily flow of the Mississippi Rover UGSG gage near Anoka is at or below 1000 cfs for five consecutive days. 325 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 149 4.3.8.12. Mitigation Even though you can’t prevent a drought from occurring, they are hard to predict, or how long they will last, there are ways you can protect from some of the consequences. Monitor Drought Conditions: this can provide early warnings for policymakers and planners to make decisions through actions including: Monitor Water Supply: This can save water in the long run though the following actions: Develop a drought emergency plan. Develop criteria or triggers for drought‐related actions. Develop agreements for secondary water sources that may be used during drought conditions. Rotating crops by growing a series of different types of crops on the same fields every season to reduce soil erosion. Practicing contour farming by farming along elevation contour lines to slow water runoff during rainstorms and prevent soil erosion, allowing the water time to absorb into the soil. Using terracing on hilly or mountainous terrain to decrease soil erosion and surface runoff. Planting “cover crops,” such as oats, wheat, and buckwheat, to prevent soil erosion. Using zero and reduced tillage to minimize soil disturbance and leave crop residue on the ground to prevent soil erosion. Constructing windbreaks to prevent evaporation from reclaiming salt‐affected soil. Collecting rainwater and using natural runoff to water plants. Encourage farmers and agriculture interests to obtain crop insurance to cover potential losses due to drought. 4.3.8.13. Response When drought occurs, the water supplier and community must take action to reduce the demand for water. While increasing water supplies would be of benefit, most such remedies require more than five years to plan and construct new reservoirs, canals, and/or groundwater sources. Reducing water demand can result in significant positive effects within only a few days. Voluntary action from water users can result in up to 25% water use reduction for short periods of time. Mandatory restrictions have resulted in as much as a 40% reduction of water use. This savings effect is directly related to a) the public’s belief that the emergency is real; b) the public clearly understands the actions required to reduce water use; and c) the active enforcement of mandatory water use restrictions. It is very important for water suppliers to understand the public seldom sustains the voluntary water conservation levels more than a few months. Drought response actions, even mandatory water use restrictions are designed to be suspended once the drought is deemed over. Drought response programs and water efficiency programs are two very different actions for two different problems. Water efficiency programs are designed to effect long‐term (even permanent) water use reductions; drought response is designed to solve short term water supply deficits. Water efficiency programs can reduce the impact of subsequent droughts, but water efficiency strategies continue beyond the term of a drought. Water efficiency planning is usually based on the economics of avoided costs or least cost planning. Drought response is meant to solve an emergency supply shortfall; thus, does not always need to be justified by avoided costs. 326 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 150 4.3.8.14. Recovery Like all disasters, recovery from drought can takes months to years to return to a state of normalcy. On August 7, 2012, President Barack Obama called for an "all hands‐on deck" approach to the drought at a White House Rural Council meeting. At the same meeting, the President asked that the USDA take the lead in coordinating the Federal effort to help with drought response and recovery. To support this collaboration across multiple federal agencies, the concepts and organizing principles of the National Disaster Recovery Framework (NDRF) were leveraged to promote a more integrated and cohesive response to drought. Based on the input received in the Drought Recovery Regional Meetings, the NDRF team identified “big bucket” issues to organize Federal resources identified across all applicable departments and agencies. These included technical assistance, grant programs, loan programs, and information resources. TABLE 4.3.8B shows resources for short‐term and long‐term recovery. The short‐term section provides links to agencies providing relief resources and information. The long‐term recovery section is geared more toward information to aid in mitigation and adaptation, but long‐term recovery resources are also listed. TABLE 4.3.8B Agency and Recovery Support Agency Short Term Recovery Long Term Recovery U.S. Department of Agriculture provides financial and technical assistance to drought affected areas and services The Natural Resources Conservation Service The Rural Development Program The Farm Service Agency Crop Production Losses Disaster Assistance Programs Natural Resource Protection/Private Lands Environmental Quality Incentives Program Emergency Watershed Protection Community Water and Wastewater Crop Insurance Risk Management Agency Natural Resource Protection/Private Lands Agricultural Water Enhancement Program Emergency Watershed Protection ‐ Floodplain Easement Watershed Protection and Flood Prevention Wetlands Reserve Program Conservation Technical Assistance Community Water and Wastewater Us Department of Interior The Recovery Act The Drought Water Bank DOI's Bureau of Reclamation administers the WaterSMART and water and Energy Efficiency Grants that aims to make more efficient use of existing water supplies through water conservation, efficiency, and water marketing projects. Funding is also available to promote water use efficiency program projects like rebate programs, irrigation system upgrades, water conservation education programs and to address and improve Best Management Practices. 327 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 151 Environmental Protection Agency EPA works with states to manage programs that provide financial assistance for projects that protect public health and water quality. EPA also manages the WaterSense Program, which helps consumers identify water‐efficient products, practices and programs.

Hazard Assessment: DUST STORM 4.3.9.1. Definition A dust storm is a strong, violent wind that carries fine particles such as silt, sand, clay, and other materials, often for long distances. The fine particles swirl around in the air during the storm. A dust storm can spread over hundreds of miles, rise over 10,000 feet, and can have wind speeds of at least 25 miles per hour. Dust storms usually arrive with little warning and advance in the form of a big wall of dust and debris. A common name for dust storms is Haboob, which comes from Arabic word habb meaning wind. 4.3.9.2. Range of Magnitude There are two main kinds of dust storms; one where the dust is carried along the surface, and the other where dust is lifted high into the atmosphere. Each of these dust storm types can happen individually, or together at the same time. If these two types of storms happen together at the same time, there is the potential for greater magnitude of consequences versus each type individually. Below are a few examples of dust storms from the National Climatic Data Center that have occurred in the United States since 1950. Most Recent, Minnesota: May 12, 2022: Blowing dust ahead of a serial derecho (a type of fast‐ moving extreme thunderstorm wind) spread from eastern Nebraska to Sioux Falls, SD, and up through western Minnesota, dropping visibility below ¼ mile, with zero visibility reported in places. A lighter wave of blowing dust entered the western Twin Cities area, including Hennepin County. Longest Distance: May 17, 2001, Dust from a storm in China traveled across the ocean and deposited dust from Alaska to Florida. Most Costly: June 10th, 2013, Humboldt, Nevada, $1.5 million Property Damage Deadliest: October 13, 2009, SW S.J. Valley, 3 fatalities 4.3.9.3. Spectrum of Consequences B2b Dust storms can have environmental, health, social, and economic consequences. Health consequences include poor air quality due to the increase in breathable suspended particles in the air which can be almost an instant consequence with people choking on dust or a consequence from particles suspended over time. Environmental consequence can be dust deposition on the landscape which can cause drying of leaves, and negative growth of plant and damage to crops. Some of the social impacts can be road and aviation accidents due to the poor visibility. Economic impacts can include damage to structures, and roads, costs associated with cleaning of infiltrated dust inside the houses and buildings, costs associated with accidents, material, crop, and production loss. On 75 million acres of land in the United States alone, wind erosion is still a dominant problem, with four to five million acres moderately to severely damage each year. 330 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 154 Many believe that dust storms are not a worry for urban areas. However urban communities are not immune to the harmful effects of dust storms either. One thing that is a concern when a dust storm hits a town or city is power outages and infrastructure damage. Anyone of these two things could have a negative result for a business. Also, there could be extensive damage to computers and communications equipment from the buildup of dust. The dust particles can get into buildings and businesses and work their way inside computers and telecommunications equipment, ruining the delicate technologies on the inside. Again, with many businesses today being dependent on technologies such as computers and communications equipment, this could have a negative impact on commerce. Additionally, vulnerable populations within urban or other populated areas may experience disproportional consequences from dust storms. For instance, those without shelter would have little to protect themselves from the airborne particulates and may suffer more frequent or acute respiratory distress. Those with limited mobility may find it similarly difficult to seek shelter. In all cases, persons with respiratory conditions like asthma, the elderly, infants, and anyone with compromised health may bear a greater cost from dust storms than the general population. 4.3.9.4. Potential for Cascading Effects The immediate economic impact of dust storms is significant, but it doesn't rival major natural disasters that destroy entire cities. For instance, the damage due to dust storms in China averages at about $6.5 billion per year. A single major earthquake can do damage five times that figure. However, experts argue that the real economic impact of dust storms, particularly those that originate in areas of desertification, is difficult to pin down because of the long‐term consequences they have on the livelihood of people who live in the area. When dust storms kick up in agricultural dry lands that are degraded, they remove the topsoil, which causes further desertification. As a result, farmers are forced to watch the topsoil, and their livelihood, literally blow away. This cycle, if gone unchecked, threatens to displace whole communities in some regions. 331 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 155 4.3.9.5. Geographic Scope of Hazard B1c The winds involved with dust storms can be as small as "dust devils" or as large as fast moving regional air masses. Dust storms occur most frequently over deserts and regions of dry soil, where particles are loosely bound to the surface. Dust storms don't only happen in the middle of the desert, however. They happen in any dry area where loose dirt can easily be picked up by wind. Grains of sand, lofted into the air by the wind, fall back to the ground within a few hours, but smaller particles remain suspended in the air for a week or more and can be swept thousands of miles downwind. Dusts storms can reach as high as 10,000 feet with an aerial coverage on the leading edge that can stretch for hundreds of miles. However, on average, they only travel around 25 to 50 miles. 4.3.9.6. Chronologic Patterns Dust storms are not common around Minnesota, but they can happen any time of year, and have occurred in the past. They are most common in desert regions, including the US Southwest and often are triggered by downdraft winds from monsoon thunderstorms. They are slightly more common during the afternoons and evenings than at cooler times of day, but only because of the importance of thunderstorms, which tend to be most numerous and most intense during afternoons or evenings. Otherwise, diurnal cycles of heating and cooling have no effect on dust storm behavior or probability. In Minnesota, dust storms are most likely during persistently dry conditions, and/or when dry and loose soil is also unprotected by mature vegetation. Because the growing season features higher rates of moisture conduction between plants and soils, and because the same plants will shield underlying soils from wind erosion, dust storms will tend to favor the pre‐green‐up periods of Late March into May, or late September into early November. GRAPH 4.3.9A shows the critical wind erosion period in Minnesota. It shows that March, April, and May are the periods of the year where agricultural fields are particularly vulnerable to wind erosion, and to extension dust storms, due to higher wind speeds with direction of prevailing wind than normal and low vegetative cover on fields. GRAPH 4.3.9A Critical wind erosion 0 5 10 15 20 25 30 Jan Feb March Apr May Jun Jul Aug Sep Oct Nov Dec Percent of Annual Erosive Winds Minneapolis, MN 332 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 156 4.3.9.7. Historical Data B1d The “Dust Bowl” era of the 1930s was so named because of massive dust storms that frequently ravaged the Plains during that extraordinarily dry period. During this period, Minnesota saw some of the worst dust storms in its history. In 1934, dry conditions combined with high winds to produce thick dust on five or more dates at the end of the month. February had at least six more dust storm dates, followed by 15 dates in March, and 19 dates in April, with the worst of the dust storms occurring on May 9‐10. Meteorologists at the time reported these latter dust storms were likely the most severe of their kind ever experienced in the area, with extreme soil erosion exposing and subjecting new seed to the strong winds. The most recent severe dust storm clipped western Minnesota and hit much of South Dakota head‐on during a severe weather outbreak on May 12, 2022. Intense downburst winds generated by severe thunderstorms advanced well ahead of the storms at speeds of 60‐80 mph. The region had been quite dry, and soils were loose and unprotected by vegetation. As a result, a huge cloud of thick dust raced north northeastward across the region, dropping visibilities to zero in spots, especially in Nebraska and South Dakota. Visibility below a quarter mile was common in western Minnesota. A lighter cloud of blowing dust moved into Hennepin County during the evening, though visibility was hardly reduced, and no impacts were reported. There have been no other incidents that are within the scope of this plan. 4.3.9.8. Future Trends B1e There is no current research available on the direct effects of future climate conditions on the incidence of dust storms. However, because drought conditions have the effect of reducing wetlands and drying soils, droughts can increase the amount of soil particulate matter available to be entrained in high winds, where agriculture practices include tilling. This correlation between drought conditions and dust storms means that an increase in future droughts could increase the incidence of dust storms, even though the drought is not directly related to the directly to the dust storm. 4.3.9.9. Indications and Forecasting Dust storms move quickly. Other than seeing a wall of brown dust approaching in the distance, there is not much warning before a dust storm arrives. However, they usually precede thunderstorms. So if conditions have been dry, and one can see a large cumulonimbus cloud and feel the wind is picking up, one can expect dust to be blowing with the possibility of dust storm type reduced visibilities and consequences. Dust storm events are caused by different weather systems showing different intensities and identifiable characterizes in observational systems. There are four dust storm generation types: frontal, meso‐ or small‐scale, disturbances, and cyclogenesis. Key features of cold front‐induced dust storms are their rapid process with strong dust emissions and a large, affected area. Frontal dust storms typically last 3‐5 hours with wind speeds of 36‐83 mph and typically affect an area of 7,700 to 77,000 square miles. Meso‐ or small‐scale dust storms are the most common type of dust storm including thunderstorms, convections along dry lines, gusty winds cause by high pressure, and more. The most common occurrence are thunderstorms in which the organized outflow from the downdrafts of decaying thunderstorms blows 333 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 157 dust plumes. These storms can typically last 2‐5 hours with winds from 53 to 78 mph. They produce the highest level of particle emission over a limited area, typically 2,000 to 6,000 square miles. The third type of dust storms are caused by tropical disturbances. These typically show strong concentration of dust in the air and last longer than frontal and meso‐ or small scale at 3‐7 hours with wind speeds 30 to 58 mph. The typical area covered is just 200 to 4000 square miles. The last type of dust storm occurs from cyclogenesis which is the development of strengthening or a lower pressure area. Dust storms from cyclogenesis typically last longer than the others at 4‐21 hours with wind speeds 38 to 65 mph because cyclogenesis tends to be stationary. These storms typically affect and area of 4000 to 31,000 square miles. 4.3.9.10. Detection & Warning As mentioned earlier, there is not a lot of indication for dust storms besides knowing the current conditions that may present the storm from occurring. However, with each of the types of dust storms mentioned above, there is never always a dust storm when those conditions are present. The National Weather Service in Chanhassen does not have a specific definition for when they would issue a blowing dust advisory or dust storm warning. In fact, The NWS Office in Chanhassen has never issued a blowing dust advisory or dust storm warning. However, the Grand Forks National Weather Service has. 4.3.9.11. Critical Values and Thresholds The blowing dust advisory conditions, visibilities at or below 1 mile, and dust storm warning, visibilities less than ¼ mile, are the two critical values when it comes to warning the public for public safety concerns. Among those concerns are health concerns when dust particles are inhaled. The particles that are small enough to be inhaled are known as PM10 which are particulate matter less than 10 microns in size or smaller. 4.3.9.12. Mitigation The effects of sand and dust storms can be reduced by using several health & safety measures and environmental control strategies. Large‐scale sand and dust storms are generally natural phenomena, and it may not be always practicable to prevent it happening. However, control measures can be taken to reduce its impacts. To reduce the consequences of dust events that may not reach dust storm criteria, cities can take appropriate control of dust raising factors such as increasing the vegetation cover where possible using native plants and trees as buffer. These can reduce wind velocity and sand drifts at the same time of increasing the soil moisture. Some health and safety measures that should be taken to minimize the adverse impacts due dust storms can be alerting vulnerable populations, using dust masks, and restricting outdoor activities and staying inside when dust storms are occurring. Mitigation strategies to reduce wind erosion from dust storms are lumped into two major categories: reduce the wind force at the soil surface and create a soil surface more resistant to wind forces. Some of these strategies are standing residues, planting perpendicular to prevailing winds, windbreaks, grass 334 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 158 barriers, strip cropping, or clod‐producing tillage. 4.3.9.13. Response One of the most important things to be done during the initial response is to make sure that people are safe. The role of Hennepin County Emergency Management is to coordinate resources that our municipalities may need to accomplish all response needs. 4.3.9.14. Recovery It is important to note that conditions and consequences from a dust storm may linger longer that one can see to the naked eye. There may be lingering dust in the air after a dust storm so the first step to recovery is to continue to avoid breathing in outdoor air for hours after a storm passes. From an emergency management perspective, assessing the amount of property damage, preparing a list of specific damage to property and buildings, and agriculture damage are top on the list to start the recovery process. 4.3.9.15.

Hazard Assessment: COLD, EXTREME 4.3.10.1. Definition The term extreme cold can have varying definitions in hazard identification. Generally, extreme cold events refer to a prolonged period (days) with extremely cold temperatures. An extreme cold event is when temperatures are dangerously lower than historical averages and pose risk to people, animals, and critical infrastructure (CISA, 2024). The extreme cold definition also depends on the area you live. In southern regions relatively unaccustomed to winter weather, near freezing temperatures could be considered extreme cold. In the North, extreme cold can mean temperatures well below zero. When defining extreme cold one also must mention wind chill. The wind chill temperature is an apparent temperature, or how cold it feels to people outside. Wind chill is based on the rate of heat loss from exposed skin caused by wind and air temperature. As the wind increases, it draws heat from the body, driving down skin temperature and eventually the internal body temperature. 4.3.10.2. Range of Magnitude Lowest Temperature in MN: ‐60°F (Feb 2, 1996: St. Louis County) Lowest Temperature in Hennepin County: ‐41°F (Jan 21, 1888) 336 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 160 Lowest Wind Chill in MN: ‐71 oF with new formula and ‐100 oF with old formula (Jan 9‐10, 1982) Lowest Wind Chill in Hennepin County: ‐6‐73 oF with the new formula and ‐87 oF with the old formula.

Spectrum of Consequences B2b Extreme cold temperatures have well known impacts on human health. On average, the United States sees 29 cold weather‐related fatalities each year. In 2019, there were 62 cold‐related deaths in Minnesota (MN DPH, 2019). Human and animal exposure to cold temperatures, whether indoors or outside, can lead to serious or life‐ threatening health problems such as hypothermia, cold stress, frostbite or freezing of the exposed extremities such as fingers, toes, nose, and ear lobes. Hypothermia occurs when the core body temperature is less than < 95oF. If persons exposed to excessive cold are unable to generate enough heat (e.g., through shivering) to maintain a normal core body temperature of 98.6oF, their organs can malfunction. When brain function deteriorates, persons with hypothermia are less likely to perceive the need to seek shelter. Signs and symptoms of hypothermia (e.g., lethargy, weakness, loss of coordination, confusion, or uncontrollable shivering) can increase in severity as the body's core temperature drops. Extreme cold also can cause emergencies in susceptible populations, such as those without shelter, those who are stranded, or those who live in a home that is poorly insulated or without heat (such as mobile homes). Infants and the elderly are particularly at risk, but anyone can be affected. Damage to structures due to extreme cold events is relatively low. Freezing pipes can be the largest problem. Extended periods of cold weather can increase the potential for frost depth problems. The depth to which soils freeze and thaw is important in the design of pavements, structures, and utilities. Increased depth of frost can also delay the frost thaw in the spring which would cause those in agriculture a later start to their season, which may lead to less yield of crops. Broken water mains can put significant demands on municipal public works departments. 4.3.10.4. Potential for Cascading Effects Extremely cold temperatures often accompany a winter storm, so individuals may have to cope with power failures and icy roads. Although staying indoors as much as possible can help reduce the risk of car crashes and falls on the ice, individuals may also face indoor hazards. Many homes may become too cold either due to a power outage or because the heating system is not adequate for the weather. The use of space heaters and fireplaces to keep warm increases the risk of household fires and carbon monoxide poisoning. During cold months, carbon monoxide may be high in some areas because the colder weather makes it difficult for car emission control systems to operate effectively. Carbon monoxide levels are typically higher during cold weather because the cold temperatures make combustion less complete and cause inversions that trap pollutants close to the ground reducing air quality. 337 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 161 4.3.10.5. Geographic Scope of Hazard B1c Extreme cold is typically associated with the northern states in the winter. However, extreme cold conditions can occur as far south as Texas. As mentioned in the definition, the social impact or where/how the public is accustomed to cold weather plays a factor in what is called extreme cold for a specific geographical area. GRAPHIC 4.3.10A shows an example from 2014. You can see extreme cold apparent temperatures for most of the central United States. GRAPHIC 4.3.10A 4.3.10.6. Chronologic Patterns Extreme cold outbreaks occur most commonly during the December, January, February months of the year. 4.3.10.7. Historical Occurrence B1d Extreme cold is a regular occurrence in Minnesota and in Hennepin County. There have been no incidents that are significant enough to be included in this plan. GRAPHICS 4.3.10B and 4.3.10C shows historically the frequency of lows at or below ‐10oF and highs at or below 0 degrees in Hennepin County. 338 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 162 GRAPHIC 4.3.10B GRAPHIC 4.3.10C 339 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 163 What is the coldest wind chill ever seen in the Twin Cities or Minnesota? The answer can be a little tricky because in November 2001 the formula on how to calculate the wind chill was changed. Perhaps the coldest wind chill the Twin Cities has ever seen was ‐67oF with the new formula (‐87oF with the old formula) back on January 22, 1936. The temperature was ‐34oF with a wind speed of 20mph. All traffic in the Twin Cities was severely impacted and several fatalities were caused by the cold. Without a lengthy state‐wide wind record, it is difficult to say when the coldest statewide wind chill was. There are some candidate dates though besides January 22, 1936. On January 9th and 10th, 1982 temperatures of ‐30oF and winds of around 40mph were reported in Northern Minnesota. This would translate to ‐71oF by the new formula (‐100oF by the old formula.) A few other notable extreme cold events are: 1989 Feb 3: At 6:00 AM in the Twin Cities the air temperature was ‐22oF with a wind speed of 17mph, creating a wind chill temperature of ‐49oF (by the 2001 formula). 1994 On January 13, 1994, an arctic air mass settled over Hennepin County. From January 13 to January 19, true air temperatures dropped from ‐10oF on January 13 to ‐27oF on January 19. The high temperature on January 18 was ‐16oF. Morning air temperature readings were ‐26oF in the Twin Cities at 9am with a wind chill temperature of ‐48oF (by the 2001 formula). The University of Minnesota on the Twin Cities campus closed on the 18th due to the cold and Governor Arne Carlson closed all public schools. 1996 On January 31, 1996, some of the coldest weather to ever hit Hennepin County settled over the area and remained entrenched through February 4. Minneapolis set three new record low temperatures as well as Minnesota recording the coldest day on record on February 2. A mean temperature of ‐25oF was measured that day with a high of ‐17oF and a low of ‐32oF. This was within two degrees of tying the record low temperature set in the Twin Cities and the coldest temperature recorded this century. On the same date that the Minnesota state record minimum temperature record was set on February 2, 1996 (‐ 60oF near Tower), Governor Arne Carlson cancelled schools for cold a second time. In the Twin Cities at 6am February 2, 1996, the air temperature was ‐30oF with a wind chill temperature of ‐48oF (based on the 2001 formula). Another extreme cold event took place on December 24, 1996. A strong low‐pressure system that deposited heavy snow over northern Minnesota also brought down very cold Canadian air. Temperatures fell to 15 to 35 degrees below zero. In addition, the high temperature on Christmas Day in Minneapolis was only ‐9oF. Combined with the record low temperature that morning of ‐22oF, the mean temperature for Christmas Day was ‐ 16oF. Christmas Day, 1996 set a record for being the coldest Christmas Day on record for the Twin Cities metro going back to when modern day records began in 1871. The temperature in Minneapolis fell to ‐27oF. 2004 The first wind chill warning that was issued for the Twin Cities under the new wind chill temperature formula established in 2001 was the arctic outbreak of January 29‐30, 2004. The coldest wind chill observed in the Twin Cities during that period was ‐43oF at 8:00 AM on January 30, 2004. 340 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 164 2006 In the wake of a winter storm on February 17, 2006, strong high pressure moved in and created strong winds and dangerous wind chills. The coldest wind chill seen at the Twin Cities International Airport was ‐34oF. The coldest wind chill found statewide was ‐54oF at Thief River Falls. 2014 Governor Mark Dayton cancelled K‐12 public schools statewide on Monday January 6th, 2014, due to extreme wind chills that were forecasted well in advance. The coldest wind chill temperature in Minnesota was ‐63oF at Grand Marais Airport at 9:00 AM with a ‐31oF air temperature and a 21mph wind. The coldest wind chill temperature in the Twin Cities was ‐48oF at 5:00 AM with an air temperature of ‐22oF and a 15‐mph wind. Many schools also cancelled classes the following day as well. The wind chill at 4am January 7th was ‐ 28oF at the Twin Cities International Airport with an air temperature of ‐14oF and a wind of 6mph. Statewide the coldest wind chill was ‐50oF reported at Duluth at 4:00 AM with an air temperature of ‐23oF and a west wind of 16mph. Schools were cancelled at many locations again on Thursday, January 23. The coldest wind chill in the Twin Cities on January 23 was at 2:00 AM with a wind chill of ‐37oF with an air temperature of ‐14oF and a NW wind of 15mph. The coldest statewide wind chill was ‐ 51oF at Park Rapids at 6am with an air temperature of ‐33oF and as wind of 6mph. Schools were cancelled for a fourth day across the Twin Cities on January 27 as well. Classes were also canceled for the day for the University of Minnesota. The coldest wind chill in the Twin Cities was ‐39oF at 4:00 AM (‐13oF air temp and wind NW 20mph). The coldest wind chill statewide was ‐53oF degrees at the Grand Marais Airport at 8:00 AM (‐ 26oF air temp, wind NE 16mph). Schools were cancelled once more across the Twin Cities on Tuesday January 28th. University of Minnesota classes were cancelled in the morning. The coldest wind chill in the Twin Cities was ‐29oF at 9am with an air temperature of ‐12oF and a wind speed of 8mph. The coldest wind chill in the state was ‐52oF at Fosston at 7:00 AM with air temperature of ‐33oF degrees and a wind speed of 7mph from the south. 4.3.10.8. Future Trends B1e In Minnesota, there are climate change signals showing the loss of formerly normal cold temperatures. That is saying that the coldest day of the year has warmed by about 8oF since the early 20th century and the 15 coldest days have warmed by about 7o F over the same period. GRAPHIC 4.3.10D shows this warming period of coldest temperatures from about 1970 forward. This means the coldest high temperatures have warmed dramatically since 1970 and are now warmer than at any other time on record. In addition, the high temperatures at or below zero have become much less common in recent years and may soon be the exception, rather than the rule. 341 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 165 GRAPHIC 4.3.10D While temperatures during our winter months seem to be warming, and as mentioned high temperatures at or below zero have become much less common in recent years, this does not mean we will not be seeing any extreme cold events in the future. 4.3.10.9. Indications and Forecasting The National Weather Service is responsible for forecasting all extreme cold events for Hennepin County. Typically, extreme cold events occur when a continental polar or continental arctic air mass makes its way down over Minnesota. These are air masses that originate over the ice and snow‐covered regions of northern Canada and Alaska where long, clear nights allow for strong cooling of the surface. Extreme cold typically occurs with or following a low pressure. As the system passes off to the east, continental polar or continental arctic air gets pulled down on the backside of the low pressure. 4.3.10.10. Detection & Warning The National Weather Service issues Wind Chill Advisories, Watches, or Warnings based on the following forecasted criteria: Wind Chill Advisory: Widespread wind chill values around ‐25oF to ‐34°F are expected. Wind Chill Watch: Widespread wind chill values around ‐35oF or colder are possible. Wind Chill Warning: Widespread wind chill values around ‐35°F or colder are expected. Extreme Cold Watch: The possibility of wind chill or air temperatures colder than ‐35 °F. Extreme Cold Warning: Wind chills or air temperatures colder than ‐35 °F are expected. 342 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 166 4.3.10.11. Critical Values and Thresholds Depending on where you live in the state, there are different critical values that related to the advisories, watches, and warnings listed above. The critical wind chill values for Hennepin County are ‐25oF and ‐35oF. It is at ‐25oF that exposed skin can start to see frostbite in 30 minutes of being outside. At ‐35oF, it can take only 10 minutes for exposed skin to be susceptible to frostbite. 4.3.10.12. Mitigation Education and Awareness Programs Educating the public regarding the dangers of extreme cold and steps they can take to protect themselves when extreme cold occurs. Organize outreach to vulnerable populations, including establishing and promoting accessible heating centers in the community. Encourage utility companies to offer special arrangements for paying heating bills. Educate homeowners and builders on how to protect their pipes including locating water pipes on the inside of building insulation or keeping them out of attics, crawl spaces, and vulnerable outside walls. Informing homeowners that letting a faucet drip during extreme cold weather can prevent the buildup of excessive pressure in the pipeline and avoid bursting. 4.3.10.13. Recovery Depending on the consequences that occurred during the extreme cold event, recovery can be short or long. Recovery time from frostbite depends on the extent of tissue that was affected. It can take sometimes up to three months to determine the extent of the damage. When it comes to recovery from deep frost depth, it can take months to years to recover from consequences of broken water mains or broken roadways, or crop yield. 343 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 167 4.3.10.14.

Hazard Assessment: WINTER STORM, BLIZZARD, EXTREME SNOWFALL 4.3.11.1. Definition Winter storms produce intense snowfall rates and/or large accumulations that can immobilize entire regions and paralyze cities, stranding commuters, closing airports, stopping the flow of supplies, and disrupting emergency and medical services. The weight of snow can cause roofs to collapse and knock down trees and power lines. Homes, farms, and businesses may be isolated for days. The cost of snow removal, repairing damages, and the loss of business can have severe economic impacts on counties and municipalities. In Hennepin County, virtually all winter storms are generated by the convergence of moisture and cold temperatures associated with low‐pressure systems. Blizzards represent the most dangerous class of winter storms, combining strong winds with falling or freshly fallen snow to reduce visibility for a period of time. Technically, they are defined as three hours or more of sustained winds or frequent gusts of 35 mph or higher in falling or blowing snow, and visibilities reduced to a quarter mile or less. The strong winds create deadly whiteout conditions that bring traffic to a standstill, enabling the wind‐driven snow to form dangerous drifts that are impossible for many vehicles to pass. In addition, the strong winds are often accompanied by falling temperatures and low wind chills, subjecting stranded motorists to life‐threatening conditions that may persist for 24 hours or more. Lastly, the strong winds of blizzards exert additional stress upon structures if they were already straining under the load of heavy snow. All winter storms have some combination of cold air, moisture, and lifting mechanisms that turn the moisture into precipitation. Most winter storms affecting Hennepin County are associated with extratropical cyclones (low‐pressure systems). Typically, the heaviest snow and blizzard conditions are found on the left side of the path of the storm system.

Source NOAA, http://www.nws.noaa.gov/os/winter/resources/Winter_Storms2008.pdf Unfortunately, blizzards are not consistently tracked and are difficult to diagnose retroactively. Moreover, most major winter storms in Hennepin County have not prompted Blizzard Warnings. In fact, one of the last NWS‐issued Blizzard Warning in Hennepin County was on November 1‐2, 1991, during the infamous Halloween Blizzard. However, many winter storms have produced Blizzard warnings in neighboring counties, along with winds in Hennepin County that significantly compounded the impacts from accumulating snow. Therefore, to avoid confusion and the misattribution of impacts, in this report, a blizzard is any accumulating snow event known to have a significant wind‐driven and blowing snow component. While many winter storms produce sleet and/or freezing rain, Hennepin County Emergency Management recognizes these as distinct hazards and will cover them separately. 4.3.11.2. Range of Magnitude A given location in Hennepin County sees 24‐hour snowfall totals over six inches once or twice per year on average, though there have been years with five or more such events. Blizzards, on the other hand, recur approximately once every 3‐4 years in western and northwestern parts of the county, and every 6‐ 347 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 171 8 years inside the 494‐694 loop. It should also be noted that blizzard conditions can occur without large snowfall accumulations. These “ground blizzard” situations are most common in rural Minnesota, but can occur in open areas of Hennepin County, west of the I‐494 corridor, and especially west of MN highway 101.

Spectrum of Consequences B2b Outdoor life safety hazards: Severe winter storms and blizzards are often accompanied by falling temperatures and dangerous wind chills. Persons caught outside unprepared can face disorientation, frostbite, hypothermia, and death. A quarter of winter storm casualties occur among those caught outside in the storm. Power outages/utilities: Heavy snow can cause power outages from direct loading on electrical wires, and more commonly from indirect sources, for example when tree limbs become overloaded with snow and fall onto wires. Heavy, wet snow can cause widespread power outages, and strong winds exacerbate this impact. The duration of service outages is typically related to the complexity and magnitude of the outage pattern, along with the ability of crews to get to repair sites. Thus, high‐volume, heavy, wet, wind‐driven snow events are associated with higher outage numbers and longer service delays. Structural failure: Heavy snow will can cause roof collapse, not just at residences, but at larger commercial facilities as well. Large roof spans lacking consistent support are especially vulnerable. The former Hubert H Humphrey Metrodome Stadium in Minneapolis failed three separate times from excessive snow loads causing the Teflon canopy to tear. Transportation: By far the greatest and most common impacts from winter storms in Hennepin County are to the transportation infrastructure, but there is no strict threshold above which heavy snow is guaranteed to produce a particular impact. Stranded vehicles and snow removal costs increase with greater accumulations, but accidents and spinouts are often a function of prior road conditions, driver preparedness and awareness, and the consistency of the accumulating snow. For instance, from January 31‐ February 2, 2004, a well‐forecast series of winter storms produced widespread 8‐11" snowfall totals across the Twin Cities, but a relatively small impact, owing to preparedness, and the generally fluffy nature of the snow. By contrast, a much smaller event on March 8 that same year, produced only 1‐3 inches, but did so unexpectedly and within a 2‐hour window. This "surprise" event caused hundreds of spinouts and accidents and forced the closure 348 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 172 of the I‐94 exit at Highway 280. The NWS estimates that 70% of winter storm related casualties result from vehicular accidents. Heavy snow impedes traffic, creates hazardous travel conditions, and requires plowing and surface treatment to keep roads passable. It also significantly reduces visibilities, which compromises driver reaction times. In blizzard conditions, the effect of wind further restricts visibilities, often to zero, and can easily disorient drivers. Stranded drivers and those forced to leave their vehicles because of accidents are often directly exposed to the harsh conditions outside their vehicles and can quickly find themselves in a life‐threatening situation. Airports frequently experience significant delays, and it is common for all runways to close for a time during major winter storms. 4.3.11.4. Potential for cascading effects Heavy snow and blizzard conditions can occupy a large portion of any strong, cold‐season extratropical cyclone, and as a result can precede, follow, or be accompanied by a wide range of weather conditions. Situational awareness is key to understanding if and how the effects of winter storm conditions will be compounded by the following hazards. Flooding: Unusually intense and/or repetitive snowfalls can drain local governments of their resources, as crews put in long hours to maintain roads, and clear debris. As the heavy snow melts, it poses flooding risks for area streams, basements, low‐lying intersections, and other areas prone to ponding. Heavy rainfall events falling onto or just after the melting of a large snowpack pose immediate flooding threats, as soil storage capacity is often very limited. In April of 2001, heavy rains in southern Minnesota caused considerable flooding, after an unusually long and snowy season left a large snowpack and saturated soils. Extended power outages: A severe winter storm that knocks out power becomes much more dangerous as the time to restore service increases. This is especially true of storms that are followed by a rapid drop in temperatures. Residences and facilities dependent on electrical power for heating or heat distribution can become dangerously cold within hours of power loss. Sometimes a heavy snowfall event or blizzard occurs shortly after a major ice storm. In these cases, the ice produces the initial critical loading, but then the snow and/or wind acts as the “final straw,” resulting in severe and widespread power outages. In these situations, the snowstorm or blizzard is just another link in a chain of cascading hazards already in progress. Overexertion: Snow removal after a major event often results in a casualty spike related to overexertion resulting from attempting to dislodge stranded vehicles and clear snow from sidewalks and driveways. It is a major cause of winter‐related fatalities in the US. Severe weather: In rare situations, a major winter storm can follow a significant severe weather event. An infamous tornado‐blizzard combination affected Janesville, WI on November 11, 1911. The tornado killed nine people and was followed almost immediately by a historic cold front that brought blizzard conditions within a couple hours of the tornado’s passage, as temperatures fell from the 60s and 70s into the teens. On April 26, 1984, a strong, killer tornado hit Minneapolis and St. Anthony, and was followed within three days by up to 10 inches of snow. Most recently, 349 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 173 on March 31, 2014, a confirmed tornado struck near St. Leo in Lyon County MN, while a Blizzard Warning was already in effect. 4.3.11.5. Geographic Scope of Hazard B1c A given winter storm may affect several hundred thousand square miles over a period of days, and often will have an instantaneous footprint of 50,000 square miles, under which dangerous winter weather conditions are occurring. The swath of all precipitation including rain and thunderstorms may cover an area the size of several Midwest states. Winter storms have occurred in virtually every part of the US, except for coastal southern California, parts of the Sonoran Desert, and southern Florida. The most severe winter storms are found in the Central and Northern Plains, and downwind of the Great lakes, and along the East Coast. Comparatively, Minnesota experiences storms that generally produce lesser snowfall totals and/or weaker winds. 4.3.11.6. Chronologic patterns (seasons, cycles, rhythm) Winter storm season in Minnesota extends from late October through April, with peak frequencies from late‐November through mid‐March. Historically, February has had the fewest major snowstorms. However, since 2004, February has become remarkably more active, while March has become less so. 4.3.11.7. Historical data/previous occurrence B1d The Twin Cities has had dozens of major winter storms since the late 19th century, with 25 calendar‐day snowfalls of 10 inches or greater, and 26 two‐day totals of at least 12 inches (TABLE 4.3.11A). TABLE 4.3.11A Historical 2‐day snowfall totals of 12” or greater in the Twin Cities. Events in bold are known blizzards in Hennepin County since 1940. Date ending Total (in.)

Notable recent examples include March 1‐2, 2007, and February 21, 2014, when 6‐12 inches of snow were finished off with 25‐40 mph winds. Following are more detailed accounts of some of the area’s most noteworthy winter storms. The Armistice Day storm of November 11, 1940 is the defining blizzard of the 20th century in Minnesota and remains the storm against which all other blizzards in this state are compared. It was a high‐impact, high‐mortality blizzard affecting a huge swath of Minnesota, Wisconsin, Iowa, and the Dakotas. The storm began as a low‐ pressure area over Colorado on the morning of November 10, which then swung northeastward and intensified rapidly as it passed over La Crosse and eventually Lake Superior on the 12th. Initially warm conditions gave way to rapidly falling temperatures, and rain turning to extremely heavy windswept snow. Winds were sustained above 30 mph over much of Minnesota, with gusts exceeding 65 mph in some areas. Snowfall rates at times were as high as three inches per hour. Snowfall totals of 15‐25 inches were common across Minnesota, including Hennepin County. The long duration of the storm, combined with its rapid onset and its severity contributed to 1/22/1917 16.0 3/4/1985 16.7 3/29/1924 12.0 3/31/1985 14.7 3/13/1940 15.6 12/1/1985 15.9 11/12/1940 16.7 11/1/1991 26.7 3/23/1952 14.1 11/30/1991 14.3 3/12/1962 12.7 3/9/1999 16.0 3/18/1965 12.2 12/11/2010 17.1 3/23/1966 13.6 2/21/2011 13.8 Surface pressure chart on November 11, 1940 351 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 175 extreme losses, including 49 deaths in Minnesota alone‐ many of whom were stranded motorists who could not navigate the enormous snow drifts that were up to 15 feet high in open sections of Hennepin County. Over a dozen of the dead were hunters who were dressed for pleasant weather and were caught off‐guard and stranded on islands in the Mississippi River. One train derailed, two were involved in a head‐on collision, and one could not complete its route because of the snow. The regional death toll exceeds 150, with many of the non‐Minnesota deaths coming from numerous capsized Great lakes vessels. “Storm of the Century”, January 10‐12, 1975. Formed by a then‐record‐setting low pressure system, this storm only produced 4‐8” of snow in the Twin Cities but hit areas to the west and north much harder. There, hurricane‐force winds gusts and blinding snowfall were common, with accumulations of up to 27 inches and drifts of 10‐ 20 feet in open country. Ice accumulated over one inch in parts of southwestern and southern Minnesota, and the combination of ice, heavy snow, and severe winds produced thousands of power and telephone outages. The storm claimed the lives of 35 Minnesotans, 21 of whom suffered heart attacks. The Red Cross provided food and shelter to over 17,000 people. Despite the heavy losses, the storm was well anticipated, and forecasts are credited with keeping the casualty toll in check. Back‐to‐Back Record‐Breakers, January 20‐22, 1982. A low‐pressure system interacting with an exceptionally air mass in retreat produced a broad swath of heavy snow over much of Minnesota on January 20. Widespread daily totals of 10‐20 inches were common, and the Twin Cities recorded 17.1”, which broke the all‐time daily snowfall record that had been set during the Armistice Day storm. As the storm wound down and exited the region on the 21st, a more potent low‐pressure system emerged from the Colorado Plains. This system intensified and moved into the region on the 22nd, producing heavy snow, sleet, ice, thunder, and blizzard conditions, prompting the closure of interstates 90 and 35 for part of the day. Snowfall totals of 10‐20 inches were again common, this time over an even larger area. The Twin Cities recorded 17.2” on the 22nd, breaking the all‐time snowfall record that had been set just two days earlier. The extreme snow loads from these storms—in many cases greater than 30 inches—caused many residential and commercial roof failures. “Wall of White” blizzard, February 4, 1984. A fast‐moving low‐pressure system and cold front charged through Minnesota, producing 2‐4 inches of light powdery snow and sustained winds more than 40 mph, with gusts as high as 75 mph. The snow and wind were unexpected and moved southward at up to 50 mph. The sudden onset of the blizzard caused severe traffic problems in rural areas, where visibilities fell to zero and snow drifts covered many roads. Cars stalled in the snow, spun out, and motorists who ventured out were subjected to subzero temperatures and 40‐60 mph winds. The storm killed 21 people in a matter of hours, almost all from exposure, and almost all of whom had been in stranded vehicles. This storm remains the most lethal single weather event in 352 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 176 Minnesota in the last 50 years. Thanksgiving weekend Blizzard, 1985. An unusually prolonged and widespread winter storm produced several waves of heavy snow over Minnesota, Iowa, Wisconsin and the Dakotas between November 28th and December 1st, 1985. In the Twin Cities, at least 5 inches on three consecutive days, with each consecutive day producing more snow than the last—this behavior is unprecedented in the area’s recorded history and resulted in three‐ day totals in excess of 20 inches. Although the snow during the first two days of the storm was very heavy, it fell in light winds as a cold air mass remained in place over the region. The final wave of snow, however, was associated with a powerful and intensifying low pressure system, and produced a slight warm‐up, followed by strengthening winds and rapidly falling temperatures. The large geographical reach of this storm system overwhelmed Minnesota’s road networks, and many state highways and local roads became impassible and had to be closed. Thousands of travelers hoping to get into or out of Minnesota we forced to remain in place into the following work week. Halloween Blizzard, October 31 – November 2, 1991. A low‐pressure system dove into southern Texas from eastern Colorado, picked up copious moisture from the Gulf of Mexico, and then proceeded on a north‐northeast path, nearly following the central portion of the Mississippi River, before passing through Wisconsin and out over Lake Superior. This scenario and trajectory produced a historic period of heavy snow in the Twin Cities and much of eastern Minnesota, followed by intense winds and plummeting temperatures. 16” 12” 20”+ Snowfall pattern, From Nov 28 – Dec 1, 1985, modified from original, courtesy of NOAA/NCDC, December 1985. 353 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 177 The snow began around noon in the Twin Cities and intensified throughout the day. Five to 10 inches had already fallen by the end of the day, and intense snowfall continued throughout the overnight period. By daybreak on November 1st, most of the Twin Cities area already had well over a foot of snow on the ground, with heavy snow still falling. Many areas experienced a decrease in snowfall intensity beginning in the late morning, but snow nevertheless continued to accumulate at a rate of an inch every 2‐3 hours throughout the afternoon and into the evening. Winds had picked up during the morning also, and increased throughout the day, with sustained speeds between 20 and 30 mph with many gusts above 40 mph in the Twin Cities. By mid‐evening, another band of heavy snow spread across the area, as winds reached peak speeds of 25‐40 mph with gusts as high as 50 mph. Whiteout conditions permeated the entirety of Hennepin County during this period. Snow continued at a lighter pace into the 2nd and even the 3rd of November, but most of the snow had fallen, with 25‐30” totals falling on through the event. The storm prompted school closings on both Friday November 1, and Monday November 4th in some districts, as snow removal efforts were significantly behind schedule. The storm broke daily and all‐time snowfall records in the Twin Cities, and in its aftermath, the earliest subzero temperatures on record were observed. Dome Teflon Roof #3 Snowstorm and Blizzard, December 10‐12, 2010. A very potent winter storm developed over South Dakota and Nebraska on Friday, December 10th, then strengthened as it moved into Iowa through Saturday, December 11th. Moisture surged into the Upper Mississippi River Valley ahead of the system on Friday, and precipitation pushed into the region during the overnight hours. Both coverage and intensity increased during the day on Saturday, and winds increased to 25‐40 mph with higher gusts by afternoon. Snowfall totals from Halloween Blizzard. Courtesy of Minnesota DNR State Climatology Office 354 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 178 Very heavy snow accompanied this system, with widespread totals between 12 and 24 inches. The Twin Cities recorded 17.1 inches, making it the fifth largest snowstorm on record, and the largest in December. For the third time in 30 years, the excessive snow load ripped and then collapsed the Teflon roof of the Metrodome. There have been no other incidents that are within the scope of this plan. 4.3.11.8. Future trends/likelihood of occurrence B1e Research on the future of winter storms in Minnesota is lacking, but recent trends indicate a tendency towards increases in the size of the largest snowfall events. However, this increase is not yet statistically significant. Climate change on one hand is causing a rapid warming of winter, and on another hand is putting more water vapor into the atmosphere. Therefore, it is plausible that snowstorm intensity could increase, even as seasonal snowfall decreases. However, using data from the Twin cities and Minnesota in general, there is no evidence that seasonal snowfall is decreasing, even though significant winter warming is well underway. It is possible that the current trend of an increase in high‐end snowfall events will continue. Using the Twin Cities snowfall record from 1900‐2015, a daily snowfall of just of six inches can be expected annually. The 10‐year snowfall amount for a calendar day is just over 12 inches. These values can be analyzed for durations of up to 7 days and return periods of up to 100 years. Snowfall totals from December 10-12, 2010, storm.

Using the same data somewhat differently, we can assess the expected frequency of common daily snowfall amounts. Frequency with which a daily snowfall total at a point in Hennepin County will equal or exceed a given amount: 4.3.11.9. Indications and Forecasting The Twin Cities/Chanhassen forecast office of the National Weather Service is the official forecasting authority for major winter weather events affecting Hennepin County. High‐intensity winter storms are usually well anticipated by the numerical weather prediction models, often up to a week in advance, and forecasters tend to have high awareness of potentially dangerous winter conditions two days or more before they develop. 356 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 180 Warning Products Remarks Blizzard Warning Sustained wind or frequent gusts greater than or equal to 35 mph accompanied by falling and/or blowing snow, frequently reducing visibility to less than 1/4 mile for three hours or more. A major life safety hazard is ongoing or imminent. Danger is greatest for those traveling or caught outdoors. May be issued 2‐4 times per year in open areas of far southern and western Minnesota. Very rare in Hennepin County; one was November 1‐2, 1991. Winter Storm Warning Significant and dangerous winter weather is expected, generally within 24 hours. Six or more inches of snow, not to exceed 48 hours, half an inch of sleet and/or forecaster discretion: a combination of snow, sleet, freezing rain, blowing snow, and/or wind leading to significant impacts. This product spans a large range, from heavy snow events with little or no wind, to major wind‐driven events that produce near‐blizzard conditions. Typically, 2‐4 issued for Hennepin County per winter. Snow Squall Warning The occurrence of snow squalls (short bursts of intense snow) meeting or exceeding one or both of the following conditions: Visibility 1/4 mile or less in snow with sub‐freezing road temperatures. Often accompanied by wind gusts greater than 30 mph. Plunging temperatures sufficient to produce a flash freeze, along with a significant reduction in visibility from falling and/or blowing snow. Additional factors to consider: Time of day. Highways and interstates impacted. These are polygon‐based warnings that last usually an hour or less. Larger and longer events are covered by Winter Storm Warnings. Severity tags: General (no tag): Used frequently. Snow squall conditions are expected or observed, but mitigating actions, combined with societal context, will reduce the threat to safe travel. "SIGNIFICANT" tag: Used only when suspected or observed A quick onset snow band with intense snowfall with potential impacts. 357 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 181 Warning Products Remarks conditions, both meteorological and non‐meteorological, suggest a substantial threat to safe travel, such that WEA is warranted to alert all devices in the path of the squall. Watch Product Name Winter Storm Watch Significant and dangerous winter weather is possible, generally within 72 hours. Blizzard conditions with visibility less than a quarter mile due to falling and/or blowing snow and frequent wind gusts to 35 mph, for three hours or more. Six or more inches of snow with an event, not to exceed 48 hours in length. A quarter inch of ice. A half inch of sleet. Forecaster discretion: a combination of snow, sleet, freezing rain, blowing snow and/or wind leading to significant impacts. As certainty about an event approach, it may be “upgraded” to a warning. Many become lower‐standing Advisories, and about 1/10 Watches end up with no Warning or Advisory product. Advisory Product Name Winter Weather Advisory Winter weather that causes inconvenience but is not dangerous if proper caution is exercised. 3‐6 inches of snow. Bowing snow, causing local visibility reductions. Less than a half inch of sleet. Less than a quarter inch of ice. Forecast discretion: a combination of light snow, sleet, freezing rain, blowing snow, and/or wind leading to impacts. In ideal situations, progression of NWS products used will include a Hazardous Weather Outlook, Watches, and then Warnings or Advisories. 4.3.11.10. Critical Values & Thresholds The baseline for a winter storm product (i.e., Watch or Warning) is generally 6 inches in 12 hours or 8 inches in 24 hours. The baseline for an Advisory is generally 3 inches in 12 hours. However, NWS forecasters may issue Watches, Warnings and Advisories at lesser thresholds if other hazards or concerns warrant a different standard. 4.3.11.11. Preparedness Before the storm strikes, homes, offices, and vehicles should be stocked with an emergency kit. At home or work, primary concerns are primary concerns are loss of heat, power and telephone service, and a shortage of supplies in prolonged or especially severe and disruptive events. Essential supplies include: 358 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 182 Flashlight and extra batteries Battery‐powered NOAA Weather Radio and portable radio to receive emergency information. Extra food and water such as dried fruit, nuts and granola bars, and other food requiring no cooking or refrigeration. Extra prescription medicine Baby items such as diapers and formula First‐aid supplies Heating fuel Emergency heat source: properly ventilated fireplace, wood stove, or space heater Fire extinguisher, smoke alarm; test smoke alarms once a month to ensure they work properly. Extra pet food and warm shelter for pets Back‐up generator (optional) but never run a generator in an enclosed space. Carbon monoxide detector Outside vents should be clear of leaves, and debris, and cleared of snow after the storm. In vehicles, the supplies in GRAPHIC 4.3.11A are essential for winter storm survival. GRAPHIC 4.3.11A Source: NWS Winter Storm Safety (http://www.nws.noaa.gov/om/winter/before. shtml) If traveling on the road for a significant length of time, be aware of the weather forecast, especially if you will have long drives with large distances between towns. Stay "connected" via television, radio, NOAA Weather Radio, or social media. Major winter storms rarely occur without warning, although road travel can subject motorists to rapidly changing, sometimes unexpected weather conditions. Thus, check forecasts throughout your route each day before your leave, and plan accordingly. 4.3.11.12. Mitigation 359 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 183 Education and Awareness Programs ● Vehicle fleet crews and others who spend substantial time on the road should be familiar with NWS warning products, jurisdictions, and be familiar with how to obtain pertinent information. All professional drivers should carry winter weather survival supplies. ● Homeowners and commercial properties should be aware of snow load safety and best practices for preventing roof damage. See FEMA document P‐957, “Snow Load Safety Guide” (January 2013) ● Members of the general public should understand the risks posed by winter storms, and should review the information available at https://dps.mn.gov/divisions/hsem/weather‐ awareness‐preparedness/Pages/winter‐storms.aspx. 4.3.11.13. Recovery Recovery from a major snow event can take days, or even weeks if it is complicated by a combination of cold weather, power outages, fallen trees, ice, or snow. In forested areas, logging activities may be significantly impacted, and fuel loads may exacerbate the potential for wildland fire. In addition to power outages, persistent wind loading on structures has at times caused gas line ruptures. 4.3.11.14.

Hazard Assessment: WINDS, NON‐CONVECTIVE HIGH 4.3.12.1. Definition Non‐convective high winds are rare, long‐lasting, sustained events that can pose significant life safety risks and produce widespread damage over a large area, while originating from sources unrelated to thunderstorms (i.e., not related to tornadoes or thunderstorm downbursts). In the Upper Midwest and most of the US, they form in association with intense and/or rapidly intensifying mid‐latitude cyclones (low pressure systems). “Wake lows” developing behind thunderstorms have been observed to produce relatively prolonged bouts of non‐convective strong winds in Minnesota‐‐sometimes resulting in damage‐‐ but these events are best considered within the spectrum of consequences and cascading effects resulting from derechos and other severe thunderstorms events. The most common scenario in Minnesota, occurring 1‐3 times per year on a statewide basis, is for a prolonged (multi‐hour) period of sustained 30‐45 mph winds, with frequent gusts to 60 mph, and isolated gusts as high as 70 mph. These events tend to result in sporadic minor structural damage, and occasionally cause isolated injuries or even deaths. A more dangerous class of events occurs roughly once or twice per decade in Minnesota, and produces a pocket of enhanced wind speeds, often sustained above 45 mph for several hours, with gusts exceeding hurricane force. These events produce massive wind loadings that can result in significant infrastructural and property damage, and the most extreme among them yield death and injury rates that resemble those of tornado outbreaks. Unfortunately, the meteorological differences between these two classes of events are quite subtle, and identifying the potential for the higher‐impact extreme cases remains a forecasting challenge. In fact, every instance of them on record in the Upper Midwest has been under‐forecast, in some cases significantly. Like derechos, there is no specific National Weather Service warning product for them. Most events in Minnesota have occurred during High Wind Warnings, within lower‐priority Wind Advisories, and even during Blizzards Warnings. Those latter cases will be considered under Blizzards and will be discussed only briefly here. Further complicating matters, no standardized database or method for cataloging non‐convective extreme winds exists. Therefore, precise statistics on areal extent, duration, and total impact are lacking. 4.3.12.2. Range of magnitude Maximum event (Hennepin): measured gust 89 mph at MSP on October 10, 1949 Maximum event (non‐Hennepin): measured 100 mph at Rochester on October 10, 1949 Maximum duration: 36 hours, Wisconsin, October 26‐27, 2010 Satellite image of the October 26, 2010 cyclone that set low pressure records in Minnesota and produced 24 hours of non‐convective severe‐threshold winds covering over 100,000 square miles. 362 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 186 Maximum sporadic wind damage footprint: 1000 mi long x 450 mi wide, November 10, 1998, and October 26‐27, 2010 Maximum extreme wind damage footprint (MN): 400 mi long x 200 mi wide, October 10, 1949 Event Type Frequency per decade Maximum sustained winds (mph) Maximum wind gusts (mph) Damaging wind duration (hr) Extreme wind duration (hr) Footprint High Wind 10‐30 30‐45 55‐70 4‐8 NA Isolated minor structural damage covering an area the size of MN. Injuries/deaths in 5‐ 10% of events Extreme Wind 1‐2 45+ 75‐100 6‐24 3‐6 Isolated minor structural damage covering several states. Significant infrastructural and property damage covering dozens of counties. Numerous injuries/deaths per event common. 4.3.12.3. Spectrum of Consequences B2b Non‐convective winds killed nine Minnesotans between 1980 and 2005, with several other deaths possible between 2006 and 2014. Estimates suggest 20‐40 additional deaths occurred between 1940 and 1979. Thus, with at least 30 deaths (and possibly as many as 55) since 1940, non‐convective extreme winds clearly present a life safety risk on par with those of tornadoes and convective storm hazards. Research has shown that non‐convective wind fatalities are like derecho fatalities, in that the majority of them occur outdoors, in boats, or in vehicles. Only 5% of documented US non‐convective wind deaths between 1980 and 2005 occurred within structures. By contrast, over 70% of tornado‐related deaths occur within buildings or homes, illustrating that people are less likely to seek shelter during non‐ convective high winds than during tornadoes. Summary of typical versus extreme non‐convective wind events 363 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 187 Unlike derechos, the peak frequencies of non‐convective extreme winds occur during the mid‐spring and especially mid‐fall transition seasons. This timing minimizes the number of outdoor recreational activities and reduces the potential exposure to wind‐related hazards. The notable exceptions are 1) Minnesota’s fishing opener, typically during the first half of May, at the end of the spring risk period, and 2) Minnesota’s hunting seasons, which span the heart of the peak risk in October and November. Boaters face substantial risks during non‐convective high wind events. The reduced friction of open water often increases wind speeds and wave heights and threatens to capsize boats. Once overturned or submerged, a boat’s occupants will be subject to the seasonally cold water, which poses serious risks for hypothermia and eventual drowning. Given the harsh conditions, rescue operations can be difficult, if not impossible. Several of the known deaths during the Armistice Day storm of 1940 were from skiffs that capsized in the 40‐60 mph winds, hours before snow began to fall. The prolonged nature of non‐convective high wind events means that hunters and others spending time outdoors face extended risk exposure from falling trees. In urban or built‐up areas, falling trees and power lines are the most typical sources of risk. During extreme events, urban inhabitants can be injured or killed by flying debris. In rural areas, outbuildings are often damaged, and barns frequently collapse. Sources and locations of US non‐convective wind fatalities, modified from Ashley and Black 2008 (see references) 364 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 188 Occupants of cars and trucks also are vulnerable to being hit by falling trees and utility poles. Further, high profile vehicles such as semi‐trailer trucks, buses, and sport utility vehicles are frequently blown over during sustained non‐convective wind events. Though they only make up 5% of the 1980‐2005 deaths shown above, construction sites may make larger proportional contributions during periods of high economic growth, when the number of large projects multiplies. Workers have been and can be blown from ledges or scaffolding and bombarded by loose materials. Because they are so rare, the Twin Cities area has not experienced the consequences of a major non‐ convective wind event in several decades. Examination of the event in 1949, combined with what is known about derechos, suggests that a current‐era repeat would be catastrophic. The total population exposed— outdoors, on the streets, in traffic—would likely be several times larger than in 1949. Power disruptions would cover the entire metropolitan area, and thousands of roads and street segments would be blocked by fallen trees, wires, and utility poles. The breadth of an extreme system, acting on our complex and dense concentration of overhead distribution feeders, would necessitate a massive temporary workforce to restore service after an event. Outages would likely last days, which could be particularly dangerous if winter conditions followed the high winds. 4.3.12.4. Potential for Cascading Effects Non‐convective high winds can occupy a large portion of any strong extratropical cyclone, and as a result can follow, precede, or be accompanied by a wide range of weather conditions. The parent intense low‐ pressure systems frequently produce severe thunderstorms and tornadoes in areas that are later affected by the non‐convective high or extreme winds. In some cases, the dangerous winds stretch far northwestward, into the portion of the cyclone where heavy snow is falling or has fallen. In these situations, severe blizzard conditions develop, and the winds function as one of many mutually enhancing hazards. 365 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 189 Phase 1 Phase 2 Phase 3 Considering that thunderstorm hazards tend to be distributed in the southeast quadrant of a cyclone, that blizzards tend to occupy the northwestern quadrant, and that any system capable of both will tend to move northeastward through the region, it is unlikely that any given location will experience severe thunderstorms, non‐convective extreme winds, and blizzard conditions from the same system. However, a powerful system on November 11, 1911, did just that, producing killer tornadoes in Iowa, Wisconsin, Illinois, and Missouri, followed by record‐setting temperature drops of 60‐80 degrees in 6‐10 hours with blizzard conditions and wind gusts as high as 75 mph. This event is a true singularity in the central US, in that nothing else like it has ever been recorded. Perhaps the most common scenario for any one location in the Upper Midwest is that the extreme winds follow a period of inclement but otherwise non‐hazardous weather and are followed by a return to non‐ hazardous weather as well. The scenario a given event follows is determined by both relative position with respect to the center of low pressure, and the depth of cold and/or warm air and moisture available to the system as it moves through the region. Those factors, in turn, influence the likelihood of cascading effects. In Scenario 1, the primary impacts are damage and power outages, and weather conditions in the storm’s wake generally will not further escalate the situation. In all other scenarios, there is some potential for combinations of the following cascading effects. Severe weather – Virtually all known non‐convective extreme wind‐producing systems in the Upper Midwest have also produced severe weather hazards somewhere within the storm’s warm sector, which is in its southeast quadrant. Incidentally, concentrations of a system’s most extreme non‐convective winds typically follow the cold front into the southeast quadrant as well. Thus, if a sufficiently intense system produces tornadoes or straight‐line winds (both of which can form in the high‐shear environments of these systems if enough instability is present), some of the Scenario 1 Non‐hazardous weather Extreme winds Non‐hazardous weather Scenario 2 Severe convective storms Extreme winds Non‐hazardous weather Scenario 3 Non‐hazardous weather Extreme winds Blizzard & dangerously cold Scenario 4 Non‐hazardous weather Extreme winds Dangerously cold The four generalized scenarios in which non‐convective extreme winds most frequently occur in the Upper Midwest. It should be noted that a single system may produce different scenarios at different locations. The Armistice Day storm 1940 generated each of the four scenarios listed. 366 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 190 areas affected will be at risk for non‐convective high or extreme winds, generally beginning 6‐24 hours after the severe weather. This occurred in south‐central and southeast Minnesota on December 15, 2021, when severe thunderstorm winds to 75 mph or greater knocked out power and were followed by non‐convective winds of 60‐80 mph several hours later. In these situations, any debris generated by the severe weather will have the potential to become airborne and further scattered by the non‐convective winds, prolonging the hazard exposure by hours. Moreover, the sustained wind loadings will further weaken or damage already‐ compromised structures, causing the potential for further collapse. The winds will also threaten to blow down trees and power structures previously spared. Lastly, these intense non‐convective winds will add a layer of danger to ongoing search and rescue operations. Blizzard – Although the very strongest winds tend to wrap into what had been the warm sector and are often removed from the area of heavy snow, the broad area of strong and even dangerous winds can reach back into areas experiencing (or previously experiencing) winter weather conditions. In these cases, the wind hazards are compounded by falling temperatures, reduced visibilities, and slippery or obstructed roads. Winds combined with heavy snowfall can knock down trees, power lines and power poles, blocking streets and cutting some residents off from their communities. Cold – Even areas that do not experience blizzard conditions may see rapid temperature drops behind the cold front. Because these events usually occur during the transition seasons, the extent and depth of the cold air tend to be minimized. However, temperatures can fall near or below zero, and wind chill temperatures can fall to ‐25 or lower. The cold weather risks are greatest in areas that had lost power or utility service from extreme winds, as frostbite and hypothermia become serious concerns. Flash Flooding – Most of the systems capable of extreme winds move quickly enough that precipitation amounts are kept under 2 inches. However, there have been instances of prolonged heavy rainfall and at least minor flooding, raising the possibility of a joint flood/non‐convective wind disaster at some point in the future, though none have been recorded in Minnesota. The force of moving water combined with sustained strong winds would easily overwhelm stranded vehicles and would significantly hamper rescue operations. Wildland Fires – The swaths of trees toppled by non‐convective high winds can increase fuel loads on forests and escalating the risk of wildland fire. Additionally, although most non‐convective wind systems produce some precipitation, many of the extreme winds come through “dry,” and even in fair conditions. If the system passes through during a drought or other condition with unusually dry vegetation, the winds could easily enhance wildfire risk. Any existing fires would have the potential to spread rapidly and uncontrollably. 367 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 191 4.3.12.5. Geographic Scope of Hazard B1c A typical extreme wind‐producing non‐ convective event may affect well over 100,000 square miles with wind damage and may produce extreme impacts over tens of thousands of square miles. The total footprint may resemble those of derechos, but the time signature is very different because non‐convective events often affect large areas simultaneously and for much longer durations than convective weather systems. Non‐convective extreme winds have been recorded in every state, but their impacts are greatest in heavily populated areas, even though their frequencies and magnitudes may be greatest on the open Plains of the central US. The highest death rates per unit area are found in the northeastern US, between Maryland and New York state, where “nor’easters” can expose large, dense populations to hurricane‐force (or greater) winds, and along the Pacific coast. Death rates in these regions are 10 times higher than in Minnesota and the Upper Midwest, because of higher frequencies of intense low‐pressure systems, the complex topography found between the mountains and coasts induce wind‐enhancing terrain effects, and the much greater population concentrations. Within the Midwest, Minnesota appears to lie on the northwestern side of a risk corridor, which maximizes near Chicago. 4.3.12.6. Chronologic patterns (seasons, cycles, rhythm) Non‐convective extreme winds associated with strong low‐pressure areas are most common during the fall and spring transition seasons, when the polar jet stream’s mean track is near the Upper Midwest and when continental temperature gradients are strong. Although strong cyclone development is more common in spring than in fall, the conditions favoring explosive intensification are more common during autumn, and thus, October and November have by far the highest frequency for non‐convective extreme winds. 4.3.12.7. Historical data/previous occurrence B1d The record of non‐convective extreme wind events in Minnesota is incomplete, owing to the lack of adequate instrumentation, documentation, and categorization. Knowing the true frequency of extreme winds in Minnesota would help estimate the likely recurrence of impacts on the modern landscape and population. The following events are those known to have produced significant non‐convective wind impacts in Minnesota and the surrounding region.

Extreme non‐convective winds capsized skiffs used by hunters in southern Minnesota, and produced impossible navigation on the Mississippi River, which forced at least 12 hunters to shelter on islands, where they ultimately froze to death. The winds wrecked large vessels on Lakes Michigan and Superior, resulting in 59 fatalities. From Minnesota east into Michigan and Ohio, winds were sustained at 35 mph or greater for several hours, with many stations recording average speeds more than 50 mph. Gusts of 70‐80 mph are believed to have been common throughout the region. The strongest winds were over Wisconsin, Illinois, and western Michigan, to the south and southeast of the intensifying low‐ pressure center. The winds blew down utility poles, and cut power and communications to much of Minnesota, Wisconsin, Illinois, and Michigan, creating a dangerous situation as temperatures fell into the teens and single digits. The event produced all four extreme wind scenarios described previously in different parts of the region. Across much of Wisconsin, Lake Michigan and Lower Michigan, the dangerous, prolonged winds of 40‐60 mph (gusting up to 80 mph) were the only significant hazard posed by the storm. Over Iowa and Illinois, tornadoes and severe thunderstorms swept through the area during the morning, and then non‐ convective sustained winds of 25‐45 mph (gusting 55‐70 mph) blew for 8‐12 hours following the passage of the strong cold front. Over western Iowa, much of Minnesota, northwestern Wisconsin and the eastern Dakotas, non‐hazardous weather gave way to strong winds gusting up to 70 mph, severe blizzard conditions, and dramatically falling temperatures; these conditions stranded and killed at least two dozen motorists. Lastly, the central and western Dakotas had wind gusts to 65 mph, little or no snowfall, but dangerously cold temperatures. On October 10, 1949 The most severe non‐convective wind event on record in Minnesota struck most of the state and produced over 75,000 square miles of derecho‐level damage. Minneapolis recorded seven straight hours of sustained winds above 40 mph, three hours of sustained winds above 50 mph, and two hours of gusts exceeding 75 mph, including a maximum gust of 89 mph. In Rochester, a 100‐mph wind gust was recorded. Boat works facilities were demolished on Lake Minnetonka, as well as numerous other Minnesota lakes; docks were destroyed, and sailboats were piled onto the shores of Minneapolis lakes; windows were blown out of homes, storefronts, and office buildings; and many brick buildings partially collapsed. In downtown Minneapolis, large signboards were twisted, the 65‐foot chimney of the Sheridan Building fell onto and severely Surface weather map, Nov 11, 1940. Shaded area represents region of wind impacts. Dark area represents hurricane‐force wind gusts. Modified from La Crosse NWS. 369 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 193 injured several people, and workers on upper floors of the Foshay Tower fell ill from motion sickness due to the extreme swaying of the building. The winds inflicted destruction or severe damage upon barns, windmills, water towers, and grain elevators throughout rural Minnesota. The event claimed 27 lives region‐wide (four in MN), and severely injured hundreds (at least 100 in MN). Many of the casualties were caused by blunt trauma from flying or falling objects, and lacerations from flying glass. Northern States Power counted approximately 4800 broken lines and 600 broken poles in southern Minnesota alone. An additional 48 broken poles were counted in the Fergus Falls area. In some areas, outages lasted into early November. Losses exceeded $100 million USD (2014) at a time when there was far less infrastructure and property than there is today. This storm system produces a band of occasionally heavy rain that in some cases fell into the howling winds, producing visibilities near zero at times. The rain itself otherwise had a marginal impact (no significant flooding, no damage), and although severe weather was reported well to the south of the region, no other significant hazards preceded or followed the extraordinary winds in Minnesota and the Upper Midwest. On November 10, 1998, An explosively intensifying low pressure system tracked from Kansas to western Lake Superior, producing a wide array of dangerous weather conditions, punctuated by a deadly, long‐lasting bout of non‐convective extreme winds. The storm set the statewide low‐pressure record (at the time), with 962.7 millibars registered at both Albert Lea and Austin. Although most of Minnesota had widespread 30‐50 mph winds, with gusts up to 75 mph, the most devastating winds stretched from central Iowa, through the majority of Wisconsin, and into Upper and western Michigan. These areas experienced up to 18 hours of sustained 35‐50 mph winds with frequent gusts of 65‐75 mph, and many gusts exceeding 85 mph, including a 93‐mph gust recorded at the La Crosse NWS office. Wind gusts exceeded 85 mph over far southeastern Minnesota. Surface weather map, Oct 10, 1940. Shaded area represents region of wind impacts.

The record‐breaking extra‐tropical cyclone October 25‐27, 2010 This system brought a widespread severe weather event and serial derecho to the lower‐Midwest, followed by a massive, 2‐day non‐convective high wind event that stretched from the Dakotas and Nebraska to Michigan. The sea‐level pressure of 955.2 millibars at Bigfork, MN shattered the previous state record set by the November 10, 1998, storm system. The reading at Bigfork is also the lowest on record anywhere in the Central US and is a mere 0.2 millibars from the record for contiguous US. Despite the extraordinarily low pressure, the enormous area occupied by non‐convective high winds, and the unusually long duration, this event lacked the wind severity of those in 1949 and 1998. 60 mph gusts were observed at most stations in the storm's 8‐state footprint, but not a single station recorded an 80‐mph gust. The winds produced nearly 500,000 power outages (at one point or another), toppled thousands of trees and power lines, but produced fewer casualties (2 fatalities and 8 injuries), and less property and infrastructural damage than the other systems. This result is not well understood, because wind speed and impacts tend to be highly and strongly correlated with the strength of the cyclone, as represented by its lowest sea‐level pressure. It is possible that this event, for a currently unknown reason, failed to produce or incorporate the dynamical and mesoscale features that typically produce extreme winds in high‐intensity systems. 373 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 197 The October 2010 event was also unusual because it produced pockets of excessive rainfall. Typically, strong regional winds aloft with these systems prevent thunderstorms from training and ensure that precipitation is not prolonged. Thus, the highest precipitation total is usually kept below 2 inches. In this case however, numerous clusters of thunderstorms formed just east of the advancing low center, producing widespread heavy rainfall. As the cyclone reached peak intensity, its forward motion slowed dramatically, and heavy stratiform precipitation (eventually changing to heavy snow) impacted many of the same areas that received repetitive thunderstorms.

Rainfall associated with October 25‐27 non‐convective high wind event. Courtesy NWS Duluth. 374 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 198 of precipitation, with isolated reports of over 5 inches, resulting in flooded intersections, submerged roads, and minor damage to businesses and residences. The locations receiving the heaviest rainfall were in the same position with respect to the cyclone center as areas that often receive the most intense non‐ convective winds; fortunately, however, this storm did not produce such winds, and there were few or no compound flooding/extreme wind effects. December 15, 2021 An unusual winter situation unfolded during this evening as a muggy airmass and a developing cyclone produced intense thunderstorms that raced northeastward from Nebraska into southeastern Minnesota, producing 22 tornadoes in the state, along with extensive straight‐line wind damage. After the storms cleared the area, the intensifying low‐pressure system responsible for them approached, with an “eye‐like” center of circulation and a large area of strong non‐convective winds. The winds moved into the same areas damaged by the severe thunderstorms. Rochester, for instance, recorded 77 mph wind gusts with the severe thunderstorms, and then three hours of 55‐70 mph non‐convective gusts, with another peak of 77 mph just before midnight local time. Throughout southern Minnesota, non‐convective wind gusts reached 60‐75 mph, producing tens of thousands of power outages as a much colder air mass settled into the region. The non‐convective winds were quite strong, especially considering the severe weather barrage they had followed, but the peak winds remained below the levels of those witnessed in 1949 and 1998, likely because this cyclone was not quite as intense, and because it was still gaining strength as the strongest winds passed through Minnesota. 4.3.12.8. Future trends/likelihood of occurrence B1e Non‐convective high winds are relatively rare, occurring, on average, fewer than three times per year in Minnesota. Extreme events are even rarer, and only affect some part of the state approximately once or twice per decade. Open areas of the state in the west and south are more conducive to extreme thunderstorm winds than other areas, but extreme non‐convective winds do not appear to follow that pattern. If anything, extreme winds, and especially the impacts of them, are slightly more common in the hilly and tree‐filled eastern parts of the state than on the open prairies. The frequency of non‐convective extreme wind in Minnesota is directly tied to the frequency of intense mid‐latitude or extratropical cyclones. Unfortunately, the physical link between explosive cyclogenesis (the process that leads to intense low‐pressure systems) and human‐caused climate change, is not well understood, so research into the future of these systems has been inconclusive, with results depicting all possible scenarios. Eye‐like feature seen in eastern Nebraska on December 15, 2021, as severe thunderstorms advance through southeastern Minnesota and intense non‐convective winds move northeastward with the circulation. 375 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 199 Consultation of all available research suggests that extreme non‐convective winds have a frequency like high‐end tornado events, with recurrence intervals on the order of multiple decades within Hennepin County. 4.3.12.9. Indications and Forecasting Forecasting authority for non‐convective high wind events rests with local National Weather Service forecast offices. High‐intensity mid‐latitude cyclones are usually well anticipated by the numerical weather prediction models. As a result, forecasters tend to have high awareness of potentially strong winds 2 days or more before they develop. In ideal situations, progression of NWS products used will include a Hazardous Weather Outlook, High Wind Watch, and High Wind Warning. In some cases, damaging and even deadly winds have arisen within Wind Advisories. Despite high awareness of strong regional wind potential, most non‐convective high wind events in the region, and all extreme events, have been under‐forecast. As a result, the impacts have come as surprises. An after‐action report from the disastrous 1949 event concluded that forecasters had "little evidence by which the severity might have been forecast." Although forecasting techniques have improved dramatically since that time, underestimation is still a concern. The November 10, 1998, event forecast products made no mention of winds exceeding 65 mph, yet there were dozens of separate instances of winds exceeding 80 mph throughout the region. Even the lower‐impact, October 2010 event had dozens of gusts exceeding the maximum thresholds named in forecast products. The forecasting challenges arise from a combination of low event frequency, low priority (when compared with other hazards), and limited understanding of the latest research. Recently, mechanisms contributing to cyclone‐related, non‐convective extreme winds have become better understood. Events with extreme winds share the following commonalities: Intense cyclone. The strongest 5% of cyclones in the Upper Midwest have minimum sea‐level pressure of 980 millibars or lower and produce strong regional winds. Both the likelihood and coverage of high and extreme winds increase as the minimum pressure drops, with 972 millibars serving as a threshold below which both are almost guaranteed. The first indicator that extreme winds are possible is the forecast of a sub‐980 millibar cyclone within the region. The lower the forecast minimum pressure, the greater the potential for impacts. Potential can be ascertained several days in advance. Cyclone passes north or northwest of area. Although non‐convective strong and high winds can be distributed widely throughout the cool side of any intense cyclone, the most extreme winds tend to be found to the south of the center of low pressure, especially in cyclones whose minimum pressure is below 972 millibars. This is most likely within 300 miles of the cyclone, but distances vary depending on the circulation structure. For example, the October 1949 event had its maximum impact area 150‐300 miles southeast of the low, versus 25‐150 miles to the south of the low in the November 1998 event. The second indicator that extreme winds are possible is if the sub‐980 millibar cyclone is forecast to pass northwest or north of the area. The nearer the cyclone (to the north/northwest), the greater the potential for impacts, especially if the minimum pressure is forecast below 972millibars. Potential can be ascertained 1‐3 days in advance. 376 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 200 Presence of a “sting jet” or “mesoscale dry hook.” The most intense non‐convective winds tend to form in the cool air circulation that wraps around and to the south of the cyclone, in association with one of two features. The first is the “sting jet,” which is associated with the pointed end of the comma‐ shaped cloud formation that wraps around the low. It is so named because of its resemblance to a scorpion tail. Another feature is the “mesoscale dry hook,” which is a sharp, reverse‐J‐shaped feature that forms in the tightly rotating comma head, which is found, incidentally, north, and west of the sting jet. The strongest winds are often found near the base of the hook. The two features often move closer to each other as a cyclone reaches maximum intensity. Both are associated with descending or drying air, often originating in the strong winds in the mid‐troposphere or above. If the descending air makes it to the ground, extraordinarily strong surface winds can result. The science is not sufficiently evolved to determine exactly which events were sting jets, mesoscale dry hooks, or both. However, either one is an excellent indicator of extreme wind potential when a surface cyclone is of sufficient intensity (indicator 1 above). It should be noted that these features may form in the absence of a strong cyclone, but their airflows will remain aloft and therefore will not pose serious threats. The third indicator that extreme winds are possible is the formation of a sting jet or a mesoscale dry hook (or both), which can be detected on satellite products. TABLES 4.3.12A and 4.3.12B can be used as guides for anticipating non‐convective wind impacts, based on pressure ranges, distance from the cyclone, and location relative to the cyclone.

Critical Values & Thresholds Because duration is such an important component of the wind loadings and total impacts, no firm thresholds have been determined for non‐convective wind speeds. However, research has shown that some impacts emerge when gusts exceed 60 mph. When gusts exceed 75mph, impacts are often widespread, and casualties tend to increase dramatically. 4.3.12.11. Preparedness If planning to be outdoors for a significant length of time, be aware of the weather forecast, especially if you will be well‐removed from sturdy shelter. Stay "connected" via television, radio, NOAA Weather Radio, or social media. Non‐convective high wind events rarely occur without warning, although warning lead times may be comparatively limited during the evolution of an extreme wind episode. Because protracted and extensive electrical and communication disruptions may occur, set aside emergency water and food supplies, can openers, batteries, and flashlights.

Mitigation Education and Awareness Programs ● Field construction crews, public works employees, and those who work or spend significant time outdoors should be educated about these risks. ● Members of the public should understand the risks posed by non‐convective wind events. ● Educating homeowners on the benefits of wind retrofits such as shutters and hurricane clips. ● Ensuring that school officials are aware of the best area of refuge in school buildings. ● Educating design professionals to include wind mitigation during building design. Structural Mitigation Projects – Public Buildings & Critical Facilities ● Anchoring roof‐mounted heating, ventilation, and air conditioner units ● Purchase backup generators ● Upgrading and maintaining existing lightning protection systems to prevent roof cover damage. ● Converting traffic lights to mast arms. Structural Mitigation Projects – Residential ● Reinforcing garage doors ● Inspecting and retrofitting roofs to adequate standards to provide wind resistance. ● Retrofitting with load‐path connectors to strengthen the structural frames. . 4.3.12.13. Recovery Recovery from non‐convective high winds can take weeks and may be complicated by a combination of cold weather, power outages, fallen trees, ice, or snow. In forested areas, logging activities may be significantly impacted, and fuel loads may exacerbate the potential for wildland fire. In addition to power outages, persistent wind loading on structures has at times caused gas line ruptures. 4.3.12.14. References Ashley, W. S., & Black, A. W. (2008).

Hazard Assessment: ICE STORMS 4.3.13.1. Definition Ice storms are major winter weather events that produce accumulations of ice, either from rain falling in sub‐freezing surface temperatures, or from heavy sleet. In Minnesota and Hennepin County, ice storms form most commonly ahead of a warm front, resulting in warm air being lifted over colder air in place, producing precipitation that is warm enough for rain but then freezes on contact with sub‐ freezing objects. When the front is associated with strong low pressure, the precipitation can be quite heavy, with rapid ice accumulations. With weaker systems or when the front is stationary, it may produce sustained light to moderate precipitation for many hours. Either situation can lead to ice‐related impacts. If the layer of freezing air near the surface is deep enough, the precipitation will fall as sleet instead of freezing rain. The granular nature of sleet generally makes it less of a damage and safety hazard than freezing rain, but sleet is nevertheless often a part of major ice storms. 4.3.13.2. Range of magnitude Magnitude of ice accumulation is rarely measured, and most accounts are purely anecdotal. Severe ice storms in Minnesota have been reported to leave a glaze up to 3 inches thick. 4.3.13.3. Spectrum of consequences B2b Heavy accumulations of ice can bring down trees, topple utility poles, and damage communications towers, disrupting power and communications for days, while utility companies make extensive repairs. Ice also damages roofs, gutters, and downspouts, and falling tree limbs often cause devastating secondary damages to structures and vehicles. Even small ice accumulations can be extremely dangerous for motorists and pedestrians, and ice storms often result in increased accidents, falls, and injuries. The following categories represent the most common and severe consequences for ice storms: Significant ice storm damage in southwestern Minnesota in April 2013. Courtesy MPR. 382 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 206 Outdoor life safety hazards If associated with a severe winter weather system, heavy snow, strong winds, falling temperatures and dangerous wind chills may follow the ice storm. Persons caught outside unprepared can face disorientation, frostbite, hypothermia, and death. 25% of winter storm casualties occur among those caught outside in the storm. Power/utilities Ice storms can cause power outages from direct loading on electrical wires, and more commonly from indirect sources, for example when tree limbs become overloaded with ice and fall onto wires. Ice accumulations greater than a quarter inch can cause widespread power outages, and strong winds exacerbate this impact. The duration of service outages is typically related to the complexity of the outage pattern, along with the ability of crews to get to repair sites. Thus, prolonged ice storms with strong winds are associated with higher outage numbers and longer service delays. Structural damage Ice storms can damage roofs at residences, and at larger commercial facilities as well. Large roof spans lacking consistent support are especially vulnerable. Secondary damage from falling ice‐coated tree limbs is especially common. These falling limbs are often significantly heavier because of the ice and can break windows and damage downspouts and gutters. In if the rain is especially heavy, ice can penetrate vulnerable locations in roofs, deforming them and often leading to significant water damage to plaster and drywall materials inside the structure. Transportation Ice storms are especially dangerous to the transportation. Major ice storms can paralyze the entire transportation system, including public transportation and airports. Spinouts and accidents frequently number in the hundreds. However, most large ice storms are anticipated, and road treatments are possible ahead of time. Smaller events from freezing drizzle only cause minor ice accumulations, but when unforeseen, can be devastating. A thin glaze from freezing drizzle on November 20‐21, 2010, resulted in several hundred reported accidents, and at least two fatalities. 4.3.13.4. Potential for cascading effects Extended power outages An ice storm that knocks out power becomes much more dangerous as the time to restore service increases. This is especially true of storms that are followed by a rapid drop in temperatures. Residences and facilities dependent on electrical power for heat distribution can become dangerously cold within hours of power loss. Temperature profiles associated with freezing rain.

In these cases, the ice produces the initial critical loading, but then the snow and/or wind acts as the “final straw,” resulting in severe and widespread power outages. In these situations, the snowstorm or blizzard is just another link in a chain of cascading hazards already in progress. Flooding Depending on hydrological and meteorological conditions, ice storms may prime areas for both flash‐ flooding, and river flooding. Flash‐flood scenarios unfold when the glaze of ice is especially thick, temperatures rise to slightly above freezing, and a period of heavy thunderstorms or heavy rain occurs before the ice can melt. Because of ice restricting flow into storm sewers, falling rain can lead to rapid ponding on roads and low‐lying areas. If the storm water infrastructure is not obstructed, a heavy glaze on the land will prevent absorption by soils, and will direct falling rain directly into area streams, which may rise rapidly. It should be noted that these scenarios to date are extremely rare, and reports in Minnesota have been highly localized. River flooding can occur after a major ice storm if a large snowpack had been present and/or additional rain falls over a large area. The melted snow would be the initial cause of rising river levels, which would then be exacerbated by rain falling over ice, and to a lesser extent by the melting ice itself. Like flash‐ flooding, these situations are not common and would require a convergence of many factors. The main risks would occur during the late winter snowmelt period. Severe weather In rare situations, it is possible for ice storms to follow or be followed by a significant severe weather event. November, March, and April are currently the most likely months. Power outages and compromised communications from ice storms may limit situational awareness needed to heed severe weather warnings. A direct hit by a major severe weather event on an area recently affected by an ice storm would further complicate damages and compound clean‐up efforts. Similarly, an ice storm following a damaging severe weather event would threaten to worsen the impacts significantly, with additional tree, power, structural, and interior damage possible. 4.3.13.5. Geographic scope of hazard B1c Most major ice storms in Minnesota affect thousands to tens of thousands of square miles‐‐generally an area the size of 10‐20 southern Minnesota counties. There have been larger events, and ice storms in the central and southern US often cover 50‐100 thousand square miles at a time, with total footprint of up to 250 thousand square miles in some cases. The State Climatology Office has noted that historically, ice storms have tended to favor higher terrain locations just inland from the north shore of Lake Superior, and along the Buffalo Ridge in southwestern Minnesota. While ice storms have affected every part of Minnesota, these areas have elevated frequencies. 4.3.13.6. Chronologic patterns (seasons, cycles, rhythm) GRAPHIC 4.3.13A shows the peak months, historically, for ice storms in Minnesota are January and April, but the main season should be considered November through April. Rare ice storms have occurred in Minnesota in October and May. 384 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 208 GRAPHIC 4.3.13A 4.3.13.7. Historical (statistical) data/previous occurrence B1d Most parts of Minnesota average between 3 to 5 days of exposure per season. Approximately 6 to 9 hours of that time includes freezing rain. It should be noted that freezing rain and drizzle can occur while transitioning between rain and snow weather patterns. The frequency of true ice storms, however, is much lower. Thirty ice storms affected Minnesota in the 20 winter seasons between 1995‐96 and 2014‐15, yielding an approximate frequency of 1.5 per year. However, ice storms can be highly episodic and clustered in time, with no ice storms in five of those years (25%), and six events during the 1996‐97 winter alone. The following noteworthy ice storms affected various parts of Minnesota: 385 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 209 Feb. 22, 1922. Blizzard, ice and thunderstorms across Minnesota, with winds hitting 50 mph in Duluth while thunderstorms were reported in the Twin Cities. Heavy ice over southeast Minnesota with 2 inches of ice on wires near Winona. Over two inches of precipitation fell in many areas. This was also one of the largest ice storms in Wisconsin history with ice four inches in diameter on telegraph wires. One foot of ice‐covered wire weighed 11 pounds. Jan. 9‐10, 1934. Sleet and ice storm over southwest Minnesota. Hardest hit was Slayton, Tracy, and Pipestone. The thickest ice was just east of Pipestone with ice measuring 6 to 8 inches in diameter. At Holland in Pipestone County 3 strands of #6 wire measured 4 ½ inches in diameter and weighed 33 ounces per foot. The ice was described as: “very peculiar in formation being practically round on three sides, the lower side being ragged projectiles like icicles: in other words, pointed. The frost and ice were wet, not flaky like frost usually is. In handling this, it could be squeezed into a ball and did not crumble.” March 3‐5, 1935. Called “the worst ice storm in Duluth’s history,” the area covered by this storm was centered on Duluth and extended up the Lake Superior coast to Beaver Bay, and east to Ashland, WI. The worst of the storm extended about 40 miles to the west and south of Duluth. The storm began in the evening of March 3, with rain and wet snow falling at the Duluth Weather Bureau, and a temperature of 26 degrees. By morning the snow stopped but the rain continued. Ice had accumulated to ⅜ inches by 11 AM and ⅞ inches at 4PM, at which point the lights started going out. By the morning of the 5th, ice coatings were measured at 1.5 inches and Duluth was virtually cut off from the outside world, except for short wave radio. A local ham radio operator sent the Duluth Weather Bureau reports. Four streetcars had to be abandoned in the storm, three of them in the western part of the city. A heavy salt mixture and pick axes were used to try to free the stuck streetcars. A one‐mile stretch of telephone poles along Thompson’s Hill was “broken off as if they were toothpicks” due to the ice. A Duluth, Masabi & Northern Railway engineer estimated up to 7 inches of ice on cables in Proctor. 75% of shade trees were reported ruined in Moose Lake, with thousands of trees stripped of their limbs. Hibbing also had damage due to ice with the breaking of large and small branches. The Portal Telephone Company in the city of Superior, Wisconsin noted ice from ½ to 1 ½ inches in diameter. Nov. 10‐11, 1940 (Armistice Day Storm). This destructive storm also produced up to ½ inch of ice on wires with ice thickness to 1 inch in Pine City and Lake Benton. Combined with fierce winds, damage to power poles was widespread. In correspondence with M.R. Hovde, the meteorologist in charge of the US Weather Bureau Office, Northwestern Bell reported: Northwestern Bell and Tri ‐State Telephone & telegraph Company Repairs and Replacements. $79,000 total estimated cost. Thickness of ice on wires‐ Generally 1/8‐to‐1/2‐inch diameter. 1 inch in diameter in two small areas. Time ice first began to form‐ Early morning of November 11, 1940 Length of time ice remained on wires‐ About 24 hours. Locality of heaviest ice formation‐ 1‐inch diameter in small area near Pine City. 1‐inch diameter in vicinity of Lake Benton. 386 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 210 Approximate number of wires down ‐1600 Approximate number of poles down ‐2400 Extent of delay of service‐ Average 18 hours for toll and 36 hours for exchange lines out of service. Remarks: The above covers damage to both Northwestern Bell and Tri ‐State Telephone Company plant in Minnesota. The greatest damage was in the area about 20 miles east and west of a line from Sandstone to Albert Lea. Jan. 14, 1952. Glaze, sleet and ice storm across Minnesota from St Cloud south into Iowa. 1,100 Northwestern Bell telephone wires down. The Buffalo Ridge in the Pipestone area the hardest hit with ¾ inches of solid ice on Northern State Power wires with icicles to 3 inches. Northwestern Bell reported ice to 1 ½ inches of ice on their wires in the same area. Thunder and a shower of ice pellets accompanied the storm in New Ulm and Mankato. Minneapolis General Hospital treated 81 victims of falls on icy streets. North Shore Ice Storm, March 23‐24, 2009. A vigorous area of low pressure moved out of western Nebraska on March 22, and an area of moderate rain reached northeast Minnesota after midnight on March 23rd. The surface air was warm enough in places like Ely and Hibbing for only minor ice accumulations. However, along the north shore of Lake Superior, near‐surface air temperatures remained below freezing. Moderate rain continued through the day and tapered off by the early morning hours of March 24th. Two ‐ day precipitation totals include .91 inches at Grand Marais and 1.94 inches at Duluth. The .91 inches at Grand Marais was freezing rain. Power outages began as tree branches snapped and downed power lines. Some of the places hardest hit were Two Harbors, Finland, and Grand Marais. 2,000 people were without power in Lake County. The crashing sounds of tree branches could be heard in the woods at Wolf Ridge Environmental Learning Center. November 20‐21, 2010. A dangerous weather situation set up late on Saturday November 20th and into early Sunday morning the 21st, as freezing drizzle and light freezing rain spread northward. Although ice accumulations were very light, the glaze caused treacherous driving conditions, resulting in over 400 accidents and two deaths in Minnesota. 387 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 211 Southwest Minnesota Ice Storm, April 9‐11, 2013. A slow‐moving low‐pressure system pumped copious amounts of moisture up into a subfreezing air mass, resulting in up to 48 hours of nearly continuous freezing rain in southwestern Minnesota, eastern Nebraska, northwestern Iowa, and eastern South Dakota. Just north of the freezing rain, heavy, wet snow accumulated 6‐14 inches. In southwestern Minnesota, hundreds of trees and power poles were snapped by the ice, which accumulated to nearly 1” thick near Worthington. Extensive secondary damage occurred to residences and vehicles, as tree limbs snapped off and crashed through windows. Power outages lasted days in some areas. Governor Dayton issued Executive Order 13‐03, to authorize state assistance for recovery efforts in southwestern Minnesota. There have been no other incidents that are within the scope of this plan. 4.3.13.8. Future trends/likelihood of occurrence B1e Little is known about future trends with respect to ice storm activity. On one hand, damaging ice storm frequency may decrease, as more and more winter events fall as above‐freezing liquid. Another argument is that more events that would have been snowstorms will contain freezing rain, and hence, more ice storms. Yet another line of reasoning suggests that increased wintertime moisture will result in more heavy precipitation events, including heavy rain and freezing rain. The topic has received little research attention, so there is virtually no “consensus” about what is likely to happen. 4.2.13.9. Indications and Forecasting The Twin Cities/Chanhassen forecast office of the National Weather Service is the official forecasting authority for major winter weather events affecting Hennepin County, including ice storms. High‐intensity winter storms are usually well anticipated by the numerical weather prediction models, often up to a week in advance, and forecasters tend to have high awareness of potentially dangerous winter conditions two days or more before they develop. The potential for significant ice accumulation 1‐3 days out is also monitored by the Weather Prediction Center, at NOAA/NWS headquarters. 4.3.13.10. Detection & Warning Warning authority for ice storms also lies with the Twin Cities/Chanhassen forecast office of the National Weather Service. An urgently severe ice storm will be covered by an Ice Storm Warning, which indicates 388 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 212 over a quarter inch of ice accumulation is expected. These situations may lead to damage and power outages, in addition to dangerous or impossible travel. If a severe ice storm is expected with other winter hazards, especially snow, the NWS may cover all hazards under a Winter Storm Warning. Similarly, lesser ice accumulations with lighter accumulating snow may be covered under a Winter Weather Advisory. 4.3.13.11. Critical values and thresholds Ice storm or Winter Storm Warnings will be issued when over ¼ inch of ice accumulation is expected. Damage to trees, along with power outages, increase dramatically after ½” of ice accumulation. 4.3.13.12. Preparedness Because ice storms are likely to disrupt power and disable local transportation routes, before the storm strikes, homes, offices, and vehicles should be stocked with needed supplies. At home or work, primary concerns are loss of heat, power and telephone service, and a shortage of supplies in prolonged or especially severe and disruptive events. Essential Supplies ● Flashlight and extra batteries ● Battery‐powered NOAA Weather Radio and portable radio to receive emergency information. ● Extra food and water such as dried fruit, nuts and granola bars, and other food requiring no cooking or refrigeration. ● Extra prescription medicine ● Baby items such as diapers and formula ● First‐aid supplies ● Heating fuel ● Emergency heat source: properly ventilated fireplace, wood stove, or space heater ● Fire extinguisher, smoke alarm; test smoke alarms once a month to ensure they work properly. ● Extra pet food and warm shelter for pets ● Back‐up generator (optional) but never run a generator in an enclosed space. ● Carbon monoxide detector ● Outside vents should be clear of leaves, and debris, and cleared of snow after the storm. 4.3.13.13. Mitigation Education and Awareness Programs ● Vehicle fleet crews and others who spend substantial time on the road should be familiar with NWS warning products, jurisdictions, and be familiar with how to obtain pertinent information. All professional drivers should carry winter weather survival supplies. ● Members of the general public should understand the risks posed by winter storms, and should review the information available at https://dps.mn.gov/divisions/hsem/weather‐awareness‐ preparedness/Pages/winter‐storms.aspx. 389 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 213 4.3.13.14. Recovery Recovery from a major ice storm can take days, or even weeks if it is complicated by a combination of other weather hazards. In forested areas, logging activities may be significantly impacted, and fuel loads from fallen trees may exacerbate the potential for wildland fire. In addition to power outages, persistent wind loading on structures, associated with powerful winter storms, has at times caused gas line ruptures. 4.3.13.15. References Changnon, S. A., & Karl, T.

This was based on their probability of occurrence, their impact on population, critical infrastructure, and the economy. Each participating municipality may have differing degrees of risk exposure and vulnerability compared to others due their geographic proximity to the hazard. However, many of the hazards are countywide risks due to their size and their impacts, and because not all are geographically specific. Under each map portion is a hazard ranking justification statement of why the hazard was given the ranking it received. 5.1 Hazard Ranking Maps B1b The following pages provide hazard rankings (in alphabetical order) for the following hazards: GRAPHIC 5.1A Blizzard 212 GRAPHIC 5.1B Climate Change 213 GRAPHIC 5.1C Drought 214 GRAPHIC 5.1D Dust Storms 215 GRAPHIC 5.1E Extreme, Cold 216 GRAPHIC 5.1F Extreme, Heat 217 GRAPHIC 5.1G Extreme, Rainfall 218 GRAPHIC 5.1H Flooding, River 219 GRAPHIC 5.1I Flooding, Urban 220 GRAPHIC 5.1J Hail 221 GRAPHIC 5.1K Ice Storm 222 GRAPHIC 5.1L Lightning 223 GRAPHIC 5.1M Tornado 224 GRAPHIC 5.1N Winds, Non‐Convective 225 GRAPHIC 5.1O Winds, Straight‐Line 226 GRAPHIC 5.1P Winter Storm 227 392 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 216 GRAPHIC 5.1A Blizzard 393 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 217 GRAPHIC 5.1B Climate Change 394 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 218 GRAPHIC 5.1C Drought 395 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 219 GRAPHIC 5.1D Dust Storms 396 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 220 GRAPHIC 5.1E Extreme Cold 397 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 221 GRAPHIC 5.1F Extreme Heat 398 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 222 GRAPHIC 5.1G Extreme Rainfall 399 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 223 GRAPHIC 5.1H Flooding, River 400 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 224 GRAPHIC 5.1I Flooding, Urban 401 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 225 GRAPHIC 5.1J Hail 402 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 226 GRAPHIC 5.1K Ice Storm 403 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 227 GRAPHIC 5.1L Lightning 404 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 228 GRAPHIC 5.1M Tornado 405 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 229 GRAPHIC 5.1N Winds Non‐Convective 406 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 230 GRAPHIC 5.1O Winds, Straight‐Line 407 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 231 GRAPHIC 5.1P Winter Storm 408 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 232 THIS PAGE WAS INTENTIONALLY LEFT BLANK 409 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 233 6.1. Inventories The effects of a disaster can be wide‐ranging from human casualty to property damage to the disruption of governmental, social, and economic activity. Often not considered, is the potential devastating effects of disasters on historic properties and cultural resources. Historic buildings and structures, artwork, monuments, family heirlooms, and historic documents are often irreplaceable, and may be lost forever in a disaster if not considered in the mitigation planning process. The loss of these resources is more painful and ironic considering how often residents rely on their presence after a disaster to reinforce connections with neighbors and the larger community, and to seek comfort in the aftermath of a disaster. To inventory the county’s cultural resources, the Steering Committee collected information from the following sources: National Register of Historic Places Minnesota’s National Historic Landmarks 6.2.

These become especially important after a hazard event. Critical facilities typically include police and fire stations, schools, and emergency operation centers. Critical infrastructure can also include roads and bridges that provide ingress and egress and allow emergency vehicles access to those in need, and the utilities that provide water, electricity, and communication services to the community. 7.1. Critical Facilities Index (CFI) Numbering Scoring System For this update to the mitigation plan, Hennepin County Emergency Management (HCEM) ranked the restoration priority of a facility using a score index of 1 to 5, 1 being the most critical to the overall health of the community. Jurisdiction understand this as those critical facilities within their community that must operate during times of disaster. The score is identified as an “all‐hazards” CFI, which applies to private and public critical facilities and is directly related to business continuity and continuity of government. The following are definitions of each score index: CFI Priority 1: facility is identified as "critical" to public health, safety. These include Hospitals and emergency medical facilities, emergency shelters, fire stations, police stations, prisons/jails, fire rescue facilities, water pumping and wastewater facilities, major communication facilities, major flood control structures, financial institutions, military installations, and critical electric utility facilities. If possible, must be operational within 2 hours. CFI Priority 2: facility may include some of the same types of facilities described for CFI Priority 1. These facilities provide significant public services but are deemed to be somewhat less critical by government agencies. These include Nursing homes, major water and sewer facilities, fire and police stations, minor flood control structures, fuel transfer/loading facilities (ports), airports, schools and park facilities used to support other critical government purposes. If possible, must be operational within 8 hours. CFI Priority 3: facility may include some of the same types of facilities described for CFI Priority 2 above. These facilities provide public services but are deemed to be somewhat less critical by government agencies. These include apartment complexes for the elderly, assisted living facilities, grocery distribution/large cold storage facilities, local water and sewer facilities, local fire and police stations, medical service facilities (such as dialysis centers) and facilities having critical impact on the environment. If possible, must be operational within 48 hours. CFI Priority 4: These facilities provide public services but are deemed to be somewhat less critical by government agencies, and include: supermarkets, banks, gas stations, hotels/motels, and lodging. If possible, must be operational within 72 hours. CFI Priority 5: These facilities provide a public service but are deemed to be less critical that the other priority tiers. CFI is used by HCEM with the intent for the coordination of restoration and post disaster economic re‐development and in coordination with infrastructure service providers. This information is intended to improve communication with local EOCs and other coordination centers during any type of emergency 426 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 2 – Hazard Inventory 250 event. This scoring system, as well as planning during normal operations, will ensure that community services are restored in a flexible and coordinated manner. The following communities participated in the Critical Facilities Index 1‐5 priorities risk assessment. Each community used the 19 hazards in this plan and determined if the hazard affects their pre‐identified priority 1 facilities.

The purpose of this plan is to identify the Counties major hazards, assess the vulnerability, and to reduce risk using a variety of data and best practice measures to implement mitigation projects. This plan identifies goals, objectives, recommended actions, and costs by reviewing and working on initiatives with each county jurisdiction or partner to reduce and/prevent injury and damage from hazardous events. The intent of the Plan is to provide unified guidance for coordinating mitigation efforts prior to or following a major emergency/disaster by implementing an on‐going comprehensive county hazard mitigation strategy intended to reduce the impact of loss of life and property due to effects of natural hazards. Through continued collaboration with each jurisdiction by providing staff expertise, support, training and education opportunities, Hennepin County Emergency Management will continue to increase its resiliency to minimize the effects of natural hazards. 430 THIS PAGE WAS INTENTIONALLY LEFT BLANK 431 TABLE OF CONTENTS - VOLUME 3 TABLE OF CONTENTS

INTRODUCTION The mitigation strategy provides a blueprint for Hennepin County to enhance its resiliency against a wide spectrum of natural hazards. It is based on the efforts of the Planning Team, the findings and conclusions of the Risk Assessment, and input from the public and stakeholders. The mitigation strategy includes hazard mitigation objectives and hazard mitigation actions. The objectives serve as the guiding principles for local future mitigation policy and project administration; actions serve as implemental items that support and provide a way to reach those objectives. The mitigation strategy includes a process for evaluating mitigation actions to ensure actions are feasible based on community capabilities, tied to plan goals, and effective in reducing hazard losses for current and future structures and populations. This section outlines the goals, objectives, and mitigation action evaluation and prioritization process undertaken in Hennepin County. Each jurisdiction provided objectives, actions and prioritization and are included in the Mitigation Action Plan (MAP), which can be found for each jurisdiction located in Section 3: Mitigation Plans 1.2. 2024 HENNEPIN COUNTY HAZARD MITIGATION PLAN GOALS C3a The plan goals are broad and reflect current needs and priorities of the county. They are intended to reduce long‐term vulnerability to all hazards identified in this plan. The 2024 Hennepin County AHMJMP goals were developed by the Mitigation Steering Committee and reviewed by the regional planning working group. The planning team reviewed the goals and opted to keep the goals as written. The mitigation planning goals are listed in TABLE 1‐2A TABLE 1‐2A Hennepin County Mitigation Goals Goal Number Goal 1 Minimize loss of life, injury, and damage to property, the economy, and the environment from natural and man‐made hazards. 2 Increase education, outreach, and awareness. 3 Protect natural and cultural resources. 4 Identify areas of greatest impact from hazards. 5 Enhance hazard mitigation coordination and communication with federal, state and local governments. 6 Promote disaster‐resistant future development. 7 Build and support local capacity and commitment to become less vulnerable to hazards. 8 Identify mitigation strategies for underserved communities, vulnerable populations, and those with access and functional needs. 9 Mitigate against the potential impacts of climate change on local communities, the economy, and the environment. 10 Enhance and improve the capability, capacity, and reliability of community lifelines and critical infrastructure in becoming more resistant to failure and resilient to natural hazards.

SELECTION OF MITIGATION ACTIONS E2a Selected objectives and actions are provided within this volume. This volume is a functional plan for action and is considered to be the most essential part of the mitigation planning process. This volume includes a prioritized listing of proposed hazard mitigation actions (policies and projects) for each participating jurisdiction. Each action includes accompanying information such as the department responsible for completing the action, timeline, and cost estimate. This volume provides each jurisdiction a description of their plan in implementing mitigation actions providing an opportunity to reduce vulnerability over time. Further, the volume provides a mechanism to monitor progress over time. Each action also considers the benefits and costs of an action, to ensure it is cost effective, which is included in the priority. These actions are reviewed and revised by each municipality, who prioritize these actions based on their own specific needs. 2.2. PRIORITIZATION OF MITIGATION ACTIONS C5a All actions are considered cost‐effective including a cost‐benefit review for prioritization. In addition, local knowledge or need, may necessitate a change in priority from the guidelines presented for priority below: A priority number scale has been used with 1 being top priority and sequential numbers being less priority. The scale may be limited on the number of identified actions for any objective listed. • Low Priority Projects: Projects that is associated with low or infrequent hazard probability and least likely to prevent loss of life. (Scale 8‐10) • Medium Priority Projects: Projects associated with a less probable hazard with potential to save lives or damage to property. (Scale 4‐7) • High Priority Projects: Projects identified in response to one or more of the highest probability hazards combined with the ability to save lives. (Scale 1‐3) 2.3. IMPLEMENTATION OF MITIGATION ACTIONS This volume includes several measures to ensure actions are implemented. HCEM will serve as the coordinating agency. However, each action is tied to a responsible agency or individual who will be responsible for leading the completion of the mitigation action. By assigning responsibility, it increases accountability and the likelihood of action. In addition to the assignment of a local lead department or agency, an implementation time period or a specific implementation date has been considered to assess whether actions are being implemented in a timely fashion. Further, the county continues to look for and research funding sources to implement mitigation projects in both the pre‐disaster and post‐disaster environments. Potential funding sources continue to be discussed for proposed actions listed in this volume. 436 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 3 – Community and Mitigation Strategies 10 THIS PAGE WAS INTENTIONALLY LEFT BLANK 437 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 3 – Community and Mitigation Strategies 11 SECTION 3 MITIGATION ACTIONS AND PROJECTS 3.1.

States and local governments are encouraged, but not required, to use the PRT as a checklist to ensure all requirements have been met prior to submiƫng the plan for review and approval. The purpose of the checklist is to idenƟfy the locaƟon of relevant or applicable content in the plan by element/sub‐element and to determine if each requirement has been “met” or “not met.” FEMA completes the “required revisions” summary at the boƩom of each element to clearly explain the revisions that are required for plan approval. Required revisions must be explained for each plan sub‐ element that is “not met.” Sub‐elements in each summary should be referenced using the appropriate numbers (A1, B3, etc.), where applicable. Requirements for each element and sub‐element are described in detail in SecƟon 4: Local Plan Requirements of this guide. Plan updates must include informaƟon from the current planning process. If some elements of the plan do not require an update, due to minimal or no changes between updates, the plan must document the reasons for that. MulƟ‐jurisdicƟonal elements must cover informaƟon unique to all parƟcipaƟng jurisdicƟons. Element A: Planning Process Element A Requirements LocaƟon in Plan Met / Not Met A1.

Terms Multi‐Jurisdictional Hazard Mitigation Plan‐ a countywide plan that identifies risks and ways to minimize damage by natural and manmade disasters. The plan is a comprehensive resource document that serves many purposes such as enhancing public awareness, creating a decision tool for management, promoting compliance with State and Federal program requirements, enhancing local policies for hazard mitigation capability, and providing inter‐jurisdictional coordination. Area Planning Group‐ One of four groups in Hennepin County divided by region that meet routinely to gather information, discuss issues, develop goals, prioritize goals, create approaches, prioritize approaches, and develop plans. Each step is necessary to the overall development and creation of the regional or jurisdictional plan. Disaster Mitigation Act (DMA 2000)‐ is Public Law 106‐390, also called DMA2K, is U.S. federal legislation passed in 2000 that amended provisions of the United States Code related to disaster relief. The amended provisions are named after Robert Stafford, who led the passage of the Stafford Disaster Relief and Emergency Assistance Act of 1988. Hazard Mitigation Program Grant ‐ to help communities implement hazard mitigation measures following a Presidential major disaster declaration. Hazard mitigation is any action taken to reduce or eliminate long term risk to people and property from natural hazards. The HMPG is authorized under Section 404 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act. Incident Action Plan‐ a written plan that defines the incident objectives and reflects the tactics necessary to manage an incident during an operational period. Operational Period‐ An operational period is the period of time scheduled for executing a given set of operational actions. The length of the operational period is typically 12 to 24 hours. Planning Team‐ A team whose members usually belong to different groups, functions and are assigned to activities for the same project. Public Law 106‐390‐ to establish a national disaster hazard mitigation program— (1) to reduce the loss of life and property, human suffering, economic disruption, and disaster assistance costs resulting from natural disasters; and (2) to provide a source of pre‐disaster hazard mitigation funding that will assist States and local governments (including Indian tribes) in implementing effective hazard mitigation measures that are designed to ensure the continued functionality of critical services and facilities after a natural disaster. Risk Assessment‐ is the determination of quantitative or qualitative estimate of risk related to a well‐ defined situation and a recognized threat (also called hazard assessment). Social Media‐ are computer‐mediated tools that allow people or companies to create, share, or exchange information, career interests, ideas, and pictures/videos in virtual communities and networks. Steering Committee‐ a committee that provides guidance, direction and control to a project within an organization. SECTION 6 GLOSSARY 772 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 3 – Community Mitigation Strategies 346 Vulnerability Assessment‐ the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Whole Community‐ an approach to emergency management that reinforces the fact that FEMA is only one part of our nation’s emergency management team; that we must leverage all the resources of our collective team in preparing for, protecting against, responding to, recovering from and mitigating against all hazards; and that collectively we must meet the needs of the entire community in each of these areas. Working Group‐ is an ad hoc group of subject‐matter experts working together to achieve specified goals. Title 44 CFR Part 201‐ Identification name for Emergency Management and Assistance‐ specifically Mitigation Planning within the Code of Federal Regulation. (1)‐The purpose of this part is to provide information on the policies and procedures for mitigation planning as required by the provisions of section 322 of the Stafford Act, 42 U.S.C. 5165. (2)‐The purpose of mitigation planning is for State, local, and Indian tribal governments to identify the natural hazards that impact them, to identify actions and activities to reduce any losses from those hazards, and to establish a coordinated process to implement the plan, taking advantage of a wide range of resources. 773 2024 Hennepin County All‐Jurisdiction Hazard Mitigation Plan Volume 3 – Community Mitigation Strategies 347 SECTION 7 APPENDICES APPENDIX A APPLICABLE FEDERAL AND STATE REGULATIONS A. The Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act), as amended by the Disaster Mitigation Act of 2000, provides the legal basis for state, tribal, and local governments to undertake risk‐based approaches to reducing natural hazard risks through mitigation planning. Specifically, the Stafford Act requires state, tribal, and local governments to develop and adopt FEMA‐approved hazard mitigation plans as a condition for receiving certain types of non‐ emergency disaster assistance. B. Another law relevant to hazard mitigation planning is the National Flood Insurance Act of 1968, as amended (42 U.S.C. § 4104c), which authorizes the Flood Mitigation Assistance (FMA) grant program with the goal of reducing or eliminating claims under the National Flood Insurance Program (NFIP). FMA provides funding to states, territories, federally recognized tribes, and local communities for flood hazard mitigation projects, plan development, and management costs. C. Title 44, Chapter 1, Part 201 (44 CFR Part 201) of the Code of Federal Regulations (CFR) contains requirements and procedures to implement the hazard mitigation planning provisions of the Stafford Act. D. FEMA policies are external, authoritative statements that articulate the Agency's intent and direction to guide decision‐making and achieve rational outcomes for Agency activities. The following mitigation planning guidance documents constitute FEMA’s official policy on and interpretation of the hazard mitigation planning requirements in 44 CFR Part 201.

This involves introducing a second drive-through lane and making necessary site adjustments to accommodate it, including expanding the waiting area to handle the expected increase in drive-through efficiency. MEETING DATE(S) Planning Commission: May 28, 2024 City Council: June 18, 2024 PROJECT INFORMATION Applicant: Ben Sparks Property owner: Sweet Cream Properties Golden Valley, LLC Lot size: 1.47 acres Future land use designation: Retail/Services Zoning district: C (Commercial) Existing use: Commercial Proposed use: Commercial Adjacent land use, zoning and uses: The properties to the north are guided Light Industrial, zoned LI and developed as commercial properties. The property to the south is guided Business & Professional Offices, zoned BPO and developed as Golden Valley Tire & Service. The property 785 2 to the east is guided Commercial, zoned C, and developed with Lat14 Asian Eatery. The property to the west is guided Commercial, zoned C and developed as Red Lobster. 2024 aerial photo (Hennepin County) PLANNING ANALYSIS The applicant is proposing a second drive-through lane, which will result in the loss of parking stalls on the east side of the site. This will reduce the total number of parking stalls on site from 62 to 58 stalls. The City Code requires 58 stalls for a building of this size. There are no changes to the drive-through lane front setback as all changes are internal to the site. The changes to the site layout will result in slightly less impervious surface area. The improvement includes the addition of two overstory trees, two ornamental trees, 20 shrubs and a variety of grasses and perennials. In reviewing this application, staff has examined the request in accordance with the standards outlined in §113-30 of the Code, which provides the criteria for granting a Conditional Use Permit (CUP) in accordance with Minnesota State Statute §462.357. The burden of proof rests with the applicant to demonstrate that the request aligns with the general purposes and intent of this chapter and is consistent with the Comprehensive Plan. A Conditional Use Permit (CUP) must be reviewed against the following standards: 1) Demonstrated need for the proposed use. The project has experienced a consistent rise in drive-through orders over the course of several years. Introducing a second drive-through lane will better accommodate this growing demand and change in the consumer market. 786 3 2) Consistency with the Comprehensive Plan of the City. The proposed project adheres to the Comprehensive Plan and won't result in any changes to zoning or overall use. Restaurants and drive-throughs are consistent with the land use and zoning designation. 3) Effect upon property values in the neighboring area. The additional drive-through land will not change the nature of this business and staff does not anticipate any impact on property values in the vicinity. 4) Effect of any anticipated traffic generation upon the current traffic flow and congestion in the area. The change will have no impact on traffic generation but will simply allow the business to serve more customers in the drive-through. The applicant indicates that the indoor seating demand has declined as drive-through demand has increased. The proposed development will improve traffic flow by allowing customers to queue in the drive-through, thus reducing congestion caused by site traffic. 5) Effect of any increases in population and density upon surrounding land uses. The population and density in this area will not increase due to the proposed plan. 6) Compliance with the City's Mixed-Income Housing Policy (if applicable to the proposed use). Not applicable to this project. 7) Increase in noise levels to be caused by the proposed use. The proposed use will not lead to an increase in noise levels. 8) Any odors, dust, smoke, gas, or vibration to be caused by the proposed use. There will not be any odors, dust, smoke, gas, or vibration caused by the proposed. use. 9) Any increase in pests, including flies, rats, or other animals or vermin in the area to be caused by the proposed use. The proposed use will not attract animal pests. 787 4 10) Visual appearance of any proposed structure or use. The proposed use will maintain the visual appearance of the existing building without significant alteration. 11) Any other effect upon the general public health, safety, and welfare of the City and its residents. The proposed development will improve the overall public health, safety, and welfare of the city and its residents. The Development Review Committee (consisting of staff from all departments) reviewed this item and had no additional comments or concerns. PUBLIC NOTIFICATIONS Notice was sent to all adjacent property owners as outlined in City Code Sec. 113-30-(f). At the time of this staff report, no comments were received from adjacent property owners. RECOMMENDATION Move to recommend approval of the Conditional Use Permit for a second drive-through lane based on the findings outlined in the staff report, with the following conditions: 1. The sidewalk be extended to connect from the building to the trash enclosure with a pedestrian ramp for employees to safely access the trash enclosure. 2. The applicant is required to submit a plan detailing sign placements, designs, and specifications, ensuring they meet all city code requirements. ATTACHED EXHIBITS 1. Location map 2.

Rachel Vogl, Project Manager Subject: Culver’s Drive Thru Improvements Executive Summary The owner of the Culver’s located at 8845 7th Ave North in Golden Valley proposes to modify the existing drive-thru of the restaurant. The project proposes adding a second drive-thru lane with related site work to accommodate the second lane and order point. The site proposes to extend the order waiting area to accommodate the anticipated increased efficiency of the drive-thru. Like others in the industry, this restaurant location has seen an increasing percentage of total business coming from the drive-thru and mobile orders. By upgrading the drive thru, there is potential to increase cars per hour through the drive-thru, car stacking, and overall efficiency of the site parking. This project will not increase the building square footage, nor will it alter the size of the parking lot. The project proposes the addition of a second drive-thru lane which will replace the space of existing parking stalls on the east side of the site. This will increase the efficiency of the drive-thru which limits vehicle conflicts in the existing parking field and improves traffic circulation on-site. The site proposes 58 parking stalls, not including the order waiting areas, which is a 4 stall decrease from the existing conditions. The proposed 58 stalls meet the required parking count for the site. The proposed improvements will maintain the existing curb limits on the site and add new landscape plants to the proposed curb islands. The proposed project does not significantly alter the pervious and impervious areas on the site. This project proposes a slight decrease in impervious area by adding landscaping areas to reconfigured islands near the drive-thru area. Conditional Use Permit Factors of Evaluation Summary Below is a summary of how the proposed improvements will meet the City of Golden Valley’s CUP Standards. 1. Demonstrated need for the proposed use. a. The proposed project has seen an increase in drive-thru ordering which has sustained over multiple years. Adding a second drive-thru lane will help accommodate this increase and change in the consumer market. 2. Consistency with the Comprehensive Plan of the City. a. The proposed project is compliant with the Comprehensive Plan and will not change the zoning or overall use. 3. Effect upon property values in the neighboring area. a. It will not be injurious to the use and enjoyment of surrounding property, nor will it diminish the property values in the area. 790 4. Effect of any anticipated traffic generation upon the current traffic flow and congestion in the area. a. The proposed development will generate a better traffic flow with safer areas for customers to stack in the drive thru while navigating the site. This will prevent instances of site traffic creating congestion in the area. 5. Effect of any increase in population and density upon surrounding land uses. a. The density or population in the area will not increase due to the proposed use. 6. Compliance with the City’s Mixed-Income Housing Policy a. Not applicable to this project. 7. Increase in noise levels to be caused by the proposed use. a. There will not be an increase in noise by the proposed use. 8. Any odors, dust, smoke, gas, or vibration to be caused by the proposed use. a. There will not be any odors, dust, smoke, gas, or vibration caused by the proposed use. 9. Any increase in pests, including flies, rats, or other animals or vermin in the area caused by the proposed use. a. The proposed use will not attract animal pests. 10. Visual appearance of any proposed structure or use. a. The proposed use will not significantly alter the visual appearance of the existing building. 11. Any other effect upon the general public health, safety, and welfare of the City and its residents. a. The proposed development will enhance the general public health, safety and welfare of the City.

Regular Members Absent: Ruby, Sicotte c. Student Member, Status: Benjamin Fricke, Absent d. StaƯ Members Present: Darren Groth, Assistant Community Development Director Kendra Lindahl, City Planning Consultant e. Council Liaison Present: Councilmember Denise La Mere-Anderson 2. CONSENT AGENDA: Brookins motioned to approve the consent agenda, with two minor changes to the May 13, 2024, meeting minutes. BarnstorƯ seconded. Commission voted 5-0 to approve. Vice-Chair Cohen noted that new member Van Oss was not present at the last meeting to be sworn in as a commissioner. Groth swore in Commissioner Van Oss and Van Oss gave a brief introduction of himself. 3. PUBLIC HEARINGS: CULVER’S CUP a. Conditional Use Permit (CUP) to add a second drive-through lane to the existing Culver’s restaurant in the Commercial zoning district (Section 113-92) b. Applicant: Ben Sparks, Sweet Cream Properties Golden Valley, LLC c. Location: 8845 7th Avenue N At 6:09 p.m., Lindahl started the presentation to share the details and summarize the sta Ư report of the request. She noted that the property is zoned Commercial (C) and would have changes in the northeast corner of the site to accommodate the proposed change of adding a second drive- through lane. Lindahl also shared two staƯ recommendations for conditions of approval. The first is that the sidewalk should be extended to connect the building to the trash enclosure with a pedestrian ramp for employees to safely access the trash enclosure. The second is that the applicant should be required to submit a plan detailing sign placements, designs, and specifications, ensuring they meet all city code requirements. Lindahl further stated that the CUP standards in the zoning ordinance have been met. Commissioner Segelbaum asked about the site parking figures, traƯic flow, and why the staƯ requested a sign plan, but not any other types of plans such as a lighting plan. Lindahl noted that the applicant volunteered to keep the 58 parking stalls and the sign plan was requested because of the newly proposed sign for the drive through lane and no additional changes to the existing site plan, such as lighting was proposed. 803 CITY OF GOLDEN VALLEY PLANNING COMMISSION MEETING MINUTES Tuesday, May 28, 2024 – 6 p.m. | City Hall Council Chamber 7800 Golden Valley Road Golden Valley, MN 55427 At 6:14 p.m., Ben Sparks, applicant, spoke in favor of the request and asked for the commission’s approval. Sparks introduced his agent working on the project, Rachel Vogl. Vogl responded to Commissioner Segelbaum’s questions by noting that the queuing and stacking issues at the site should be a wash because while they were losing four parking spaces, the additional drive through lane would add four more queuing spaces. Commissioner Segelbaum asked about continuing the two lanes for a longer distance south and Vogl responded that they did not want to lose any more parking. Commissioner Segelbaum asked if the 58 parking spaces was limiting to their business. Vogl stated that the 58 spaces were the City’s standard parking figure and Culver’s desired parking number. Commissioner Cohen mentioned that he ate at this restaurant often and while he thought he may need to recuse himself, he just wanted to ask about the lunch and weekend rush times and if the second lane was for peak hours. Sparks noted that the flow adds capacity and should work for all times and not just lunch. Sparks stated that the lunch and dinner orders are typically diƯerent types of orders, and each posed a unique challenge. Commissioner Segelbaum asked if Culver’s see a lot of Door Dash orders and Sparks responded that they do, but they also oƯer walk out service so people can avoid the drive through queue. Commissioner BarnstorƯ asked if the proposal considered the environmental impacts regarding additional cars idling, such as increased emissions and noise, and whether adding a lane solves the problem or induces demand. Sparks noted that the company wants people to dine in their restaurants because that is the best way to experience the freshness and cleanliness of Culver’s. He noted that they resisted Door Dash for years because of Culver’s model, but they were losing money due to long lines. Commissioner BarnstorƯ asked if the current use of iPads was helping. Sparks noted that anecdotally he has heard people say it helps, but his restaurant statistics do not show any diƯerence. Commissioner Segelbaum asked if the queue is forming in front of parking spaces. Sparks noted that they do, and it is a problem now, but they feel that adding the second lane will allow them to utilize those spaces again. Commissioner Segelbaum asked how this change will impact vehicles visiting the site from Decatur Avenue. Vogl shared that the Decatur traƯic has a choice and can make various decisions on how they use the parking lot and that most of the traƯic comes from 7th Avenue. Commissioner Segelbaum asked if the sidewalk staƯ requested would also get blocked from the queue and Vogl stated that it should not. Commissioner Segelbaum indicated that he was confused by the configuration and asked how Culver’s currently handles the driving space at the southeast corner of the lot. Vogl noted that the south side parking will remain with the entry spot still a bypass. Commissioner Segelbaum asked then where the queue went. Sparks shared that the majority of traƯic comes from 7th. Commissioner Segelbaum asked if they thought about signs for the 7th Avenue entrance to be enter only and Sparks responded that while they had not thought about that, they could if traƯic becomes a problem. Commissioner Segelbaum asked for more information regarding the sidewalk and how it connects to the trash. Lindahl clarified that no issue has been raised about the street traƯic and that the proposal eliminates two points of conflict. Commissioner Segelbaum asked if the proposal was for a sidewalk or crosswalk to avoid staƯ as pedestrians having to walk through the drive through lanes. Lindahl indicated either could work. Lindahl asked to respond to a previous question and claimed that the double drive lanes would mean less time idling. Vogl agreed. Sparks agreed by saying that while the times would not be changing much, this proposal is intended to move cars more quickly through the process of ordering and getting their food. Commissioner Segelbaum asked if a sidewalk were installed, would traƯic from the north have to drive over the sidewalk. Lindahl clarified that the sidewalk is only requested to the curbline. Commissioner Segelbaum asked if she proposed the sidewalk to extend 804 CITY OF GOLDEN VALLEY PLANNING COMMISSION MEETING MINUTES Tuesday, May 28, 2024 – 6 p.m. | City Hall Council Chamber 7800 Golden Valley Road Golden Valley, MN 55427 to the trash and Lindahl responded that is not proposed. Commissioner Brookins noted that the sidewalk as proposed by the applicant ends at a catch basin and Vogl noted that is their design. Commissioner Brookins asked hos staƯ currently takes out the trash. Sparks stated that they go in a straight line from the door to the trash and not typically down the sidewalk. Commissioner Van Oss asked if Culver’s has any issues with this way of taking out the trash. Sparks responded none. Commissioner Brookins asked if the drive through light is being relocated and Vogl noted how it is planned to stay on the island. At 6:44 p.m., Vice-Chair Cohen opened the public hearing. There were no audience members present to speak. At 6:44 p.m., Vice-Chair Cohen closed the public hearing. At 6:45 p.m., Commissioner Brookins made a motion to recommend approval of the request in accordance with the findings and conclusion in staƯ report submitted by Lindahl with the removal of the condition to extend the sidewalk. Commissioner Segelbaum seconded the motion. The Commission voted unanimously to approve the motion. 4. NO NEW BUSINESS 5.
