Call to Order Baker called the meeting to order at 7:04 pm. II. Approval of Minutes — February 24, 2003 No changes. MOVED by Kuentz, seconded by Hill, and the motion carried unanimously to approve the minutes of the February 24, 2003 meeting as submitted. III. Program/Project Updates Natural Resources Inventory: The City is in the process of performing a natural resources inventory throughout the City. The inventory has maps showing the location of natural and non-native communities and are being provided in electronic and paper format as part of this study. The April 28, 2003 Environmental Commission meeting will be a joint meeting with the Open Space and Recreation Commission and the Planning Commission. At this meeting a presentation identifying the results of the natural resources inventory will be given by Short, Elliott, Hendrickson Inc. The DNR would like the City to sign a licensing agreement allowing release of the endangered species data to the public. Currently the City is incorporating the data received from the DNR. The data will be specific but users will need to know how to present it to the public. Baker further explained the agreement to others at the meeting. NPDES Phase II: The federal government has mandated Cities with a population greater than 10,000 to comply with the NPDES Phase II permit. Golden Valley is in good shape regarding the requirements by the government. The City's permit has 44 Best Management Practices (BMPs) that it must adhere Minutes of the Golden Valley Environmental Commission March 24, 2003 Page 2 to. The City Council has approved the permit application and Lundstrom plans to submit it to the Minnesota Pollution Control Agency by March 28, 2003. Lundstrom will supply a copy of the permit to all members of the Commission. BCWMC Second Generation Plan: Under the same laws as the NPDES Phase II permit, the BCWMC is required to submit a new water management plan. This second generation plan focuses on quality water issues. This will be discussed at the next BCWMC meeting scheduled for April 17, 2003 at noon in the City Hall Council Conference room. Baker indicated he would attend. Boone Avenue North and Trunk Highway 55 Project: The City is in the preliminary design process for the reconstruction of the intersection at Boone Avenue North and TH 55. The reconstruction is needed as a result of the General Mills headquarters expansion. General Mills has added additional office space to its corporate office which will increase traffic levels at this intersection. Council has also authorized staff to purchase the property at 710 Boone Avenue North. Seventy percent of this site is wetland. The City is considering construction of a flood levy in the vicinity of this property. The levy would provide ponding space and a lift station to alleviate the flooding of the two gas stations and the intersection of Boone Avenue North and TH 55. Golden Valley has an agreement with General Mills and the City's consultant, WSB & Associates Inc. to do a water resource study of the intersection and surrounding area. The City could receive the land that was proposed for the Bassett Creek Nature preserve and part of the agreement with General Mills. This would allow the City to restore the creek back to its original flow. This may allow General Mills to develop its land near Betty Crocker Drive and General Mills Boulevard. Preliminary investigations have been started by WSB. WSB will present its findings to the Commission in the fall. Oliver will provide the Commission with the scope of work from WSB. Wirth Beach: See item number IV. Proposed Developments: None. IV. Wirth Lake A project in the BCWMC CIP included dredging subwatershed FR -5 detention pond (see attachment), located at TH 55, to improve the water quality of Wirth Lake. The Minneapolis Park Board is in the feasibility stages of this project. Lundstrom discussed the project with a representative from the Park Board. He Minutes of the Golden Valley Environmental Commission March 24, 2003 Page 3 informed Lundstrom that the project is based on funding from the Legislative Committee for Minnesota Resources (LCMR). This project is presently on hold pending the State budget cuts. Kuentz distributed Table 6, Lake Improvement Options for the Wirth Lake Watershed. Golden Valley contributes approximately 5% to these costs and the rest is funded through LCMR grants, MnDOT and the Minneapolis Park Board. Kuentz explained that the FR05 detention pond is located between the park trail and Wirth Parkway. The water control structure kept the pond level higher than the lake. Recently Kuentz noticed that the structure is failing and there is no longer a pond at this location; it is more of a direct flow into the lake. Sediment is collecting and the pond is no longer functioning as a settling area. Kuentz believes the structure should be repaired. Oliver explained that the facility is fully under the responsibility of the maintenance of the Minneapolis Park Board. Kuentz will contact Tim Brown at the Board. V. Bassett Creek Park Pond The area north of Duluth Street and west of Highway 100 has been surveyed. The Bassett Creek Park Pond gets significant settlement of sediment. This reach of Bassett Creek and this pond were identified in the Golden Valley CIP. Lundstrom distributed a project schedule. Bonestroo, Rosene, Anderlik & Associates are the City's consultant. Staff will meet with MnDOT in early May. The Commission will review the preliminary report and design. A neighborhood meeting will be held later in May. Commission members, Baker and Hill, would like to attend the neighborhood meeting to hear what the neighbors have to say about the project. Staff will get back to the Commission next month about attending neighborhood meetings. VI. Other Business Restoring Streams in Cities: At the February meeting, the Commission had asked the City to purchase a resource book called Restoring Streams in Cities. Lundstrom has bought the book and it is available to be checked out through him. Golden Valley Budget Cuts: Baker asked about the SunPost newspaper article regarding the City's budget cuts totaling nearly $600,000. Oliver explained the measures taken by management. One option is to fold the Environmental Commission under with the Planning Commission. Members opposed this option. Baker will contact the Mayor and he Minutes of the Golden Valley Environmental Commission March 24, 2003 Page 4 suggested that all Commission members contact the City Council members to discuss this matter. Baker recommended the Commission meet every other month to save dollars. Flood Damage Reduction Study: Giese asked about the status of the flood damage reduction study. Oliver advised that the floodproofing was approved by the BCWMC on March 20, 2003, and is included in their CIP. The City Council will hear this matter on April 1. Attendance of Commission members at City Council Meetings: The Commission would like members to attend the Golden Valley City Council meetings to make its present known and to get familiar with how the Council operates. The following assignments were made: April 1, 2003 Giese April 15, 2003 Baker May 6, 2003 Wessman May 20, 2003 Hill More assignments will be made in the future. Baker asked for the Council reports to be added to future Commission agendas. Members can get the agendas off the City's website along with the executive summaries for each action. VII.

Respectfully submitted, Deb Somers Administrative Assistant Department of Public Works Natural Resource Inventory Executive Summary In 2002, Short Elliott Hendrickson (SEH) completed a natural resources inventory throughout the City of Golden Valley. The City of Golden Valley was the lead implementing agency with collaborating partners that included the Minnesota Department of Natural Resources (MNDNR) and the Hennepin Conservation District (HCD). Funding was provided through a MNDNR Metro Greenways Planning Grant with an equal match provided by the City of Golden Valley. The project was administered by the Public Works Department of the City of Golden Valley (hereafter referred as the City). The primary objectives of the Natural Resources Inventory were threefold. First, to provide the City and metropolitan area with completed mapping of the Minnesota Land Cover Classification System (MLCCS). The MLCCS is a land cover classification system developed by the MNDNR. Large areas of the Twin Cities Metro have been, or are in the process of being, mapped using the MLCCS. Mapping of the City using MLCCS was the major objective and requirement of the MNDNR Metro Greenways Planning Grant. The second objective was to identify other important natural resources and resource management needs within the City. The third major objective was to provide the City with a natural resources management database that can serve as a source for future management efforts. The completed MLCCS is one of several tools to be used for long- term natural resources management and planning. The results and data collected during the study are presented as natural resource management units (RMU's). The RMUs are specific geographic areas identified by the City. Each RMU has a park or open space as a point of reference and are identified accordingly. Fourteen RMUs were determined and are shown in Figure 1. Natural resources were identified and assessed, and management opportunities addressed within each RMU. The following is a list of the RMUs included in this report in the order they are presented: 1) Medley Park 2) Wesley Park 3) Brookview Park 4) Westwood Lake 5) Laurel Avenue Greenbelt 6) Hampshire Park 7) Briarwood Nature Area 8) Wirth Park 9) South Tyrol Park 10) Shaper Park 11) Bassett Creek Nature Area 12) Mary Hills Nature Area 13) North Tyrol Park 14) Pennsylvania Woods CADOCUME-1 \dsomers\LOCALS-1\Temp\EXECUT-1.DOC In summary, the City's Natural Resources Inventory results reflect a fully developed city with established parks, open space, trails, and greenways. Most of the natural areas are mixed woodlands, forests, open water, or wetlands. Nuisance vegetation composition varies considerably, and ranges from severe infestations of European buckthorn and purple loosestrife in Wirth Park, to minor infestations of these species in the parks and open spaces in the remainder of the City. Ecological restoration needs are greatest in the vegetative communities that are infested with buckthorn and purple loosestrife. Restoration opportunities are limited in other areas. Existing trails and greenways are extensive and well planned. Potential trail and greenway opportunities are scattered within each RMU. Rare, threatened, or endangered species are limited by pre-existing development, but known occurrences are scattered throughout the City. The results and database of the MLCCS have been developed into a Geographic Information System (GIS) database for application and development of management objectives for natural resources by the City. The GIS database will be combined with the MNDNR and HCD efforts in the other Metro areas where the MLCCS has been completed. The Natural Resources Inventory for the City was completed in spring 2003.

The purpose of the work would be to identify jurisdictional wetlands within the Study area, develop a plan to enhance existing wetlands, create new wetlands, restore the meander characteristics of Bassett Creek in the reach north of Betty Crocker Drive, provide additional floodplain storage in the area, and obtain permits for this work. This project will also provide wetland credits to be deposited into a wetland bank to be used by the City, General Mills, or Golf Course. Task I — Collect and Review Background Information. As part of this task, background information will be collected from various sources. This information will include reviewing the topography, modeling information, drainage area information, soil survey information, the National Wetland Inventory, DNR Public Waters Maps, and existing wetland delineation information. Task 2A —Develop Preliminary Wetland/Upland Location Map. A map that identifies the wetland/upland locations will be completed. The purpose of this task will be to better define wetland areas and use this information to develop concept plans. This task will utilize historic aerial photo review for the area, soils and NWI mapping information, and a field visit to develop the preliminary wetland location information. No stakes will be placed around the wetlands nor will wetland edges be surveyed as part of this task. This will be completed for the following areas as shown on the attached map: • Area 1: General Mills property bounded by Betty Crocker Drive, General Mills Boulevard, the 394 ramp, and the General Mills parking lot. • Area 2: The Golf Course property. • Area 3: Wetland in the northeast corner of 7`h Avenue and Boone Avenue. 4150 Olson • Area 4: General Mills property west of General Mills Boulevard, north of Betty Memorial Highway Crocker Drive, and east of 169. Suite 300 Task 2B — Complete Functions and Values Assessment of the Wetlands. As partof this r polis task, the Minnesota Routine Assessment Method (MnRAM) will be completed for the Minnesota 55422 763541.4800 763.541.1700 FAX Minneapolis • St. Cloud • Equal Opportunity Employer February 17, 2003 Page 2 wetlands reviewed in Task 2A. This assessment will allow the City and General Mills to make m pla g decisions about these wetlands and design a wetland enhancement project to meet the needs of the City, General Mills, and the Golf Course. Task 2C — Develop Preliminary Concept Plans and Report for the Wetland Enhancement/Floodplain Storage Project. From the information gathered in the previous tasks, preliminary concept plans will be developed that will incorporate the creation of floodplain storage, creation of new wetland, and enhancement of existing wetland areas. It is anticipated that up to three meetings will be held with General Mill's staff to obtain input and make certain the plan that is developed will meet the needs of the company to a maximum reasonable extent. This concept plan will be summarized in a draft report that will be mZies. available for review with City Staff, General Mills, other local landowners, and ew reviaBased on input from these parties, the concept plan will be finalized. Task 3 — Complete Formal Wetland Delineation. Once the concept plan is finalized, a delineation of the jurisdictional wetlands will be completed for those areas that have been determined to require delineation. This delineation will be in conformance with the US Corps of Engineers Wetland Delineation Manual (1987). Depending on the options selected from Task 2, the following areas or portions of the areas could be included for delineation: Area 1: General Mills property bounded by Betty Crocker Drive, General Mills Boulevard, the 394 ramp, and the General Mills parking lot. Area 2: The Golf Course property. Area 3: Wetland in the northeast corner of 7th Avenue and Boone Avenue. Informatio from the City and General Mills has indicated that the wetland delineation north of Betty Crocker Drive has been completed and is accurate; therefore, no additional delineation is proposed in this area. This task will include delineating the site(s), surveying the site(s), and developing a Wetland Delineation Report to be used for permitting purposes. One meeting is included with this task to review the formal wetland delineation with the appropriate permitting agencies. A cost estimate for delineation of each area has been developed and is included on the attached table. Task 4 — D velop Final Design for a Wetland Enhancement/Creation and Floodplain Storage Pr 9ject. As part of this task, the information obtained in the previous tasks will be reviewed aid a final plan for wetland enhancement, wetland creation, and floodplain storage project wil be developed. This plan will consider the potential to enhance the existing wetlands, t e amount of floodplain storage needed for the TH55/ Boone Avenue Improvement Project, and the potential to create additional wetlands in the area. This plan will also be designed to in conformance with the Wetland Conservation Act and regulations of the US Corps of Engineers to provide wetland credits to the City. Excess wetland credits created by the project could be used by the City, General Mills, or the Golf Course for F. I WPW1M1473-001021703gv.doc February 17, 2003 Page 3 mitigation of future projects that impact wetlands. This task includes two meetings with City Staff to review the plans. Task 5 — Complete Final Report. The information developed from the previous tasks will be compiled into a report. This report will outline the background information collected, the results of the functions and values assessments, results of the wetland delineation, review the concept plans and discuss the plan for the enhancement and creation of wetlands within the site as well as outline the plans to provide additional floodplain storage. This report will be prepared and reviewed with the City Staff. Task 6 — Develop and Submit Permit Applications for Wetland Enhancement Design. This task includes developing and submitting the appropriate permit applications for the wetland creation and enhancement project for review and approval. It is anticipated that this plan will need to be approved/reviewed by the City of Golden Valley as the LGU for WCA, the US Corps of Engineers, the DNR, and the Bassett Creek Watershed Management Organization. This application will include a wetland banking application for excess wetland credits anticipated to be created by the project. This task anticipates up to four meetings with the agencies and associated follow up. Cost Estimate and Timeline The cost estimate to complete this work is $52,265. An itemized estimate is attached for your review. The preliminary wetland review can be completed in April/May, concept plan development in June, wetland delineation in July, and report preparation and permit application submittal by the end of the summer.

Non -point source storm water is generally the overland flow of storm water that does not originate from a single pipe, otherwise know as point -source storm water. The Phase II National Pollution and Discharge Elimination System (NPDES) permitting process requires cities such as Golden Valley to file a Phase II NPDES permit with the Minnesota Pollution Control Agency (MPCA) which addresses how the City will regulate and improve storm water discharges. The permit must include a Storm Water Pollution Prevention Plan (SWPPP) addressing all the requirements of the permit. The Public Works Department has managed the permit application process. Several Department Heads and Managers assisted staff with the permit process. Staff attended several seminars and meetings collecting information related to the Phase II program. The City also joined a consortium of Cities coordinated through the League of Minnesota Cities (LMC) and attended the workshops sponsored by the LMC. The framework for developing the City's NPDES Phase II permit application and plan is the City's existing Comprehensive Surface Water Management Plan (SWMP), adopted in August 1999. The purpose of the Golden Valley Surface Water Management Plan is to provide a complete and intensive guide and reference for managing surface water resources within the City of Golden Valley. The plan assists the City with policy decisions, water resource management, implementation priorities, regulatory program references, and capital improvement budgeting for water resource issues. Golden Valley's NPDES Phase II plan addresses the six Minimum Control Measures (MCMs) outlined in the permit requirements. Many of the Best Management Practices (BMP), required in the NPDES permit, have already been developed in accordance with the City's Surface Water Management Plan. The six Minimum Control Measures of the permit are: 1. Public Outreach and Education 2. Public Participation/Involvement 3. Illicit Discharge Detection and Elimination 4. Construction Site Runoff Control 5. Post Construction Runoff Control 6. Pollution Prevention/Good Housekeeping 2 EXECUTIVE SUMMARY The Storm Water Pollution Plan (SWPPP) was developed by the City of Golden Valley to enhance the integrity of surface water through management of the storm water runoff within the City. The SWPPP is designed to minimize the discharge of pollutants into the City's storm water system, to protect and enhance water quality, and to satisfy the appropriate requirements of the Clean Water Act of 1984. The Goal of the SWPPP is to prevent unwanted discharges into the City's storm sewer system to the maximum extent practicable. The Process Before beginning selection of Best Management Practices (BMPs) and Measurable Goals for each Minimum Control Measure required by the permit, City staff undertook a self-assessment of Golden Valley's storm water system including an evaluation of our City's conditions, needs, and practices. The objective of this process was to provide a knowledge base upon which to structure the SWPPP in order to meet the Permit's Maximum Extent Practicable standard. The self-assessment was guided by materials included in the League of Minnesota Cities NPDES Phase II MS4 Guide Plan. This self-assessment process had two major components: 1. A workshop session organized as part of the LMC Guide Plan project included a self-assessment component led by Pat Collins of AMEC Earth & Environmental. This workshop included: discussion of physical and socio-political watershed and organizational conditions and issues that should guide the selection of BMPs and Measurable Goals. review of two examples of Cities with different characteristics to demonstrate how local conditions should shape the selection of BMPs and Measurable Goals. a series of exercises in which our City staff considered the local conditions for our community and how they should guide our selection of BMPs and Measurable Goals. 2. Staff completed NPDES Phase II Program Assessment Questionnaire that was included in the LMC Guide Plan notebook. This was a twelve -page document with a comprehensive list of questions that staff used to guide them through a self-assessment activity, including consideration of a wide range of stormwater approaches. The results of this process include: a set of understandings among City staff regarding storm water management written notes regarding stormwater management completed Storm water Program Assessment Questionnaire 3 This assessment represents our knowledge of Golden Valley's storm water system and the conditions that shape it. City staff has used the results of this self-assessment process to guide our selection of BMPs and Measurable Goals that make up the SWPPP for our Permit Application. Based on this self-assessment process, the City evaluated many factors in order to meet the maximum extent practicable standard set forth in the permit. These factors include sources of pollutants, potentially polluting activities being conducted in the watershed, sensitivity of receiving waters, uses of receiving waters and other issues of specific local concern. In addition to the self-assessment process discussed above, the City considered non - storm water discharges to determine whether they should be identified as significant contributors of pollutants to our storm water system. If any of these discharges were considered significant, they were incorporated into the permit. The City of Golden Valley did not find any of the additional referenced non -storm water discharges listed above to be significant contributors of pollutants to the storm water system Funding Mechanism The City of Golden Valley established a Storm Water Utility Fee in 1992. The City's Storm Water Utility revenue is generated by fees according to land use. The Storm Water Utility Fee is the primary funding source for all storm water improvements related to the City's Surface Water Management Plan, Pavement Management Program and NPDES Phase II requirements. The following is a breakdown of the 2003 Storm Water Utility Fee revenue source: Property Type Quarterly Collection Rate Parks/Golf Courses $ 27.00(per acre Railroads 40.50(per acre Single Family - Residential 18.00(per unit Schools/Library/Churches 81.00(per acre Multiple Family 135.00(per acre Commercial/Industrial 270.00(per acre 11 GOLDEN VALLEY WATERSHED AND CITY PERSPECTIVE Primary Drainage System Bassett Creek 2 Lakes Closed Basin Secondary Drainage System Known Conveyance System (MS4) Approximately 90 outfalls entering Bassett Creek No Cross -connections Features Mild Slopes Clay Soil Types Receiving Waters Bassett Creek – Mississippi River Known pollutants -mainly phosphorus from sediment deposition and fertilizers Land Use Primarily low density residential; seventy percent of housing stock single family residential Significant Commercial, Industrial and Institutional; approximately 35% of overall land use Twenty-five Parks and Nine Nature areas within the community Three Significant Golf Courses Type of Community/Growth Older Community No significant Growth Primarily Redevelopment Emotional Environment Culture is positive Willing to spend money wisely on storm water management — Storm water management projects generally supported by City Council and Administration City Government Full-service community 126 full-time staff Staff is well educated about storm water issues Limited equipment Medium technology capabilities are in place Stakeholders Multiple City Departments are impacted by the Storm Water Pollution Prevention Plan People generally willing to abide by Local Storm water Ordinances Individual citizen and civic group volunteers available Several homeowner associations exist There are seven neighboring Phase II Communities and one Phase I Community G:\NPDES PHASE 2\SWPPP\Introduction.doc Minimum Control Measure Summary This section summarizes the existing and planned Best Management Practices (BMP) selected by the City of Golden Valley. 1.
