Public Hearing – Continued Consideration of a Major Amendment to Hidden Lakes PUD 74 Applicant: Regency Hospital Address: 1300 Hidden Lakes Parkway, Golden Valley, MN Jason Zimmerman, Planning Manager, reminded the group that this hearing is a follow‐up from a previous meeting on January 25th, due to new material. This amendment to PUD 74 would allow for an expansion of the hospital building and that would lead to necessary utility and landscape changes. April 12, 2021 – 7 pm City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 2 Zimmerman displayed a map and reviewed the zoning district and location within the City of Golden Valley. The previous meeting ended with a list of outstanding concerns and since then, there were negotiations between the hospital and the HOA Board, revisions were made to the plans: 6’ high solid wall along east edge of parking lot Additional landscaping Reduction of seven proposed parking spaces (37 vs. 44) The updated proposal includes a new private agreement between the HOA and the Hospital Board that addresses eight areas of concern: Hidden Lakes Parkway – maintenance and cost issues Employee smoking and littering Traffic speeds, stop signs, noise, deliveries, etc. New parking lot landscaping and wall Lighting Stormwater management Construction activities Future expansion This private agreement was approved by the HOA Board and hospital, then shared with residents on April 7th. This agreement is intended to manage issued outside of the PUD permit. Zimmerman recapped the details of the PUD amendment regarding the size of the addition, utility details, the existing entrance, dining/day room on the second floor, and the exterior material details. To illustrate these details, a map was displayed as well as a 3D rendition of the proposal. The updated plan recap is: Parking lot reconfiguration triggered: o Expand to the south, add 37 parking stalls o Would remain under the usual required parking ratio o Knoll and existing trees would be removed New landscaping/screening added along east edge of parking lot – both low and high Lighting would respond to the City’s “dark skies” requirements Stormwater treated/managed through an underground system Using the trip generation data for nursing homes, traffic engineers estimated that the addition would generate an estimated 42% increase in trips per day (578 to 822). Zimmerman reviewed the details surrounding community engagement, public comments, and the schedule for this item appearing before Planning Commission and the scheduled date it will appear before City Council. Staff evaluation and preliminary findings were extensive and resulted in a recommendation for approval subject to 18 conditions. City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 3 Recommendation Approval of Amendment #8 to Hidden Lakes PUD No. 74, subject to the following conditions: 1.

The location and nature of construction parking, access, delivery, staging, equipment and materials storage, and employee parking. c. A neighborhood “Hot Line” for issue resolution. Commissioner Pockl asked how the City insures the private agreements are enforced. Zimmerman responded that the City stays out of the private agreement between the hospital and the HOA. Any condition or agreement in the PUD permit has the enforcement of the PUD process. Violations will be addressed, require corrective actions, and could result in legal action. With all the conditions and the private agreement, Commissioner Johnson asked if the Planning Commission has now set itself up as a mediator and straying from its expertise in reviewing parking etc. He followed up by asking who has precedence, the HOA or the homeowners in the HOA. Zimmerman responded that staff has not inserted itself in the private agreement but together they came to the City and asked how it could be enforceable. The HOA will discuss what they intend to do to enforce their agreement. Johnson followed up that he hopes the Commission stays within its realm of ability. Chair Blum invited the Applicant to address the Commission. Dave Garmin, Applicant ‐ Regency Hospital, stated the private agreement with the HOA was a good compromise that benefits them and the HOA. Chair Blum opened the public hearing at 7:40pm. Jeff Eisenberg, President of HOA, stated staff provided a good presentation and elaborated on a background between the HOA and the applicant. Discussion between the HOA and Commissioners included resident input on and responses to the agreement. Fredda Pink 1405 Waterford Drive My husband has written quite a bit but my concern is the hospital is planning on doing a piling. I don’t know how many people are aware of the noise associated with a piling. My son is a real estate developer and he told us a few days ago that there’s a more expensive style that eliminates the constant pounding noise and potential damage to our homes. I was wondering if it would be possible to look into that, it would relieve a lot of tension. There’s also no protection for the people who face the north end of the hospital, we have a full view of the north end of the building and parking lot. That hasn’t been addressed either. City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 5 Patrick Lewis 1750 Waterford Court I wanted to clarify a few things from the presentation, there isn’t unanimous HOA Board support for the agreement and there is a difference between the homeowners and the HOA. I’ll reiterate that this project will be problematic no matter what, it’s a commercial development in a residential area. This expansion involves all the mitigations discussed to mask the issue that it’s too big of a build for this area. The hospital said they don’t have plans to expand but there’s nothing preventing them from proposing expansions in later years. The main thing I want to state again is that there isn’t an agreement between homeowners, the HOA Board doesn’t represent the homeowners, and there isn’t even agreement among the Board. Ron Schiferl 4220 Woodland Trail There’s been significant improvement since the last Planning Commission Meeting. The landscaping plan pictures look great but the actual plan proposed is to limit the trees to 6foot‐that’s exactly as high as the wall. There needs to be more variation in the plan. I hope the city works with the hospital to create more variety so it looks like landscaping. Can we add something to ensure the hospital maintains its landscaping as they have a history of not doing that. The last Planning Commission meeting there was mention that the hospital reached out to homeowners, they had not before or after that meeting. All communication has come from the HOA. My understanding is that this plan is for a two‐story building to allow for expansion on the first floor, if the hospital isn’t planning on any expansions in the future, why do they still need a two‐story building? Chair opened Commissioner discussion. The Chair asked staff to address the pilings question. Zimmerman said his understanding is that they’re not planning on using pilings but rather do spread footings. He followed up that he’s not sure how that impacts surrounding properties. A development agreement can address those issues. Displaying images from the presentation, staff addressed the concerns regarding shielding from the north end of the building and staff pointed out that most of the homes are on a hill from the hospital which may create more difficulties. Zimmerman added a condition to the PUD that landscaping must be maintained and trees will be 6 feet in height to start, not top out at 6 feet. Chair closed the public hearing at 8:11pm. Commissioners Johnson asked if the parking spaces exceed minimum amount, why is the City agreeing to this when they value green space. Staff responded that the minimum amount from the hospital is their standard amount and they’d prefer more to accommodate staff, training, visitors etc. Johnson expressed concern on this topic and feels the number of parking spaces is arbitrary. Commissioner Pockl asked if they can ask the applicant why removal of the knoll is needed. City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 6 Alan Catchpool, Applicant Engineer with Kimley‐Horn, stated that public utilities goes through the site and to the SE corner and the entrance to the parking lot is through the knoll. Those items require the knoll removal. Chair Blum noted the dedication of a conservation easement and staff responded that most of twin lakes has a conservation easement along it and the City would like to continue protecting that area. This helps prevent erosion and development and the area is not currently developed. Blum asked if it’s harder to develop on a slope as steep as the one along the hospital to the lake. Zimmerman responded that it is and was part of the hospital’s original plan but the decided against it. Blum noted to Commissioners that the area unlikely to be developed and may have less value to be dedicated as a conservation easement. Pockl asked the HOA representatives to explain how the HOA Board came to support the private agreement as a caller noted they hadn’t. Eisenberg, HOA, stated that the Board was updated after every conversation with the hospital and the Board voted unanimously to support the private agreement. Johnson referred to page 10 that the applicant wants to use motion sensors in the parking lot, and asked if that means the lot will be completely dark. Zimmerman stated the City Code has a minimum level for how the lot is illuminated. Blum discussed the building height and setbacks in the proposal. Commissioners had a discussion revolving around these items, lighting, and the easement. The discussion moved on to property maintenance, the applicant meeting requirements, and negotiations between applicant, city and HOA. Commissioner Segelbaum commended the negotiations and supports staff recommendation. Commissioner Brookins stated he supports the proposal and staff recommendation. Blum asked for more mitigating changes. Commissioner Sadeghi asked if the HOA Board mentioned the items concerning to Blum as they will feel the direct impacts. Eisenberg, HOA, responded that the private agreement, gives them more rights than they had before. The hospital needs repairs and the proposal will help that. Pockl said she’s not concerned about the setbacks or height, negotiations have been productive and the hospital improvements will have a positive impact. Pockl stated support for staff recommendations. Commissioner Johnson said he tried to consider all parties involved and doesn’t think an HOA Board has more say than the average resident. He added the process may need to change in the forward to ensure consideration of everyone’s rights. MOTION made by Commissioner Brookins, seconded by Commissioner Segelbaum to formally adopt staff findings and follow staff recommendation for approval subject to the 18 conditions as listed in the memo. Chair Blum stated he felt the final approval could be stricter. 2d: Blum suggested the language change to “install and maintain” 16: Blum suggested instead of the plan being shared, that there be more certain language. Staff took a roll call vote on the motion and it passed unanimously. City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 7 5. Public Hearing – Amendments to Future Land Use and Zoning Maps Applicant: Golden Valley Country Club Address: Northwest corner of 7001 Golden Valley Road Prior to presentation, Commissioner Sadaghei recused himself as there was a conflict of interest. Myles Campbell, Planner, summarized that the applicant is petitioning the City for both a Zoning Map Amendment and a change to the City’s Future Land Use Plan for a portion of the Golden Valley Country Club Property. Property is currently zoned I‐4 for Institutional use and the requests would result in the property being zoned “R‐1, Single Family Residential. Reguiding and Rezoning the property is the first step to allowing the site to be redeveloped for single‐family housing. Country Club approached the City in late 2019 about the opportunity to sell a portion of their property to a private developer. 7001 Golden Valley Road is in total 148.76 acres, the area being considered for rezoning is 2.25 acres. Ron Clark Construction (developer) is proposing to use the site for the development of seven single family homes. The applicant would like to use a new private road to provide access to the homes, limiting the number of new curb cuts off the public streets, and allowing for additional greenspace buffers. A PUD would be necessary and the City would require some public benefits and amenities in order to allow for flexibilities such as the private road. None of these actions can occur without change to the site’s zoning and guided land use Campbell discussed the existing conditions of the area, topography, creek location, and showed maps to illustrate these items. The approvals process prior to any redevelopment is large, if the rezoning and reguiding are approved, the applicant must then either apply for a major subdivision or a PUD. A potential approval schedule was displayed assuming each step was approved without tabling or additional review. Staff analyzed surrounding uses, traffic generation, buildable lots, and the comprehensive plan. Staff Findings The site is currently in an area with other R‐1 zoned properties, and would not be out of character with the surrounding neighborhood. More work is needed to determine the safest street access to the new residential development, but Engineering staff is not concerned about the traffic generated by the inclusion of new single‐family residential in the area. The use of this site for a residential purpose fits with a number of the goals and objectives of the Comprehensive Plan. In its Housing Chapter, the Comprehensive Plan recognizes the need for new housing in the City to maintain pace with demand, but notes the lack of available land area for a relatively City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 8 built‐out city. Rezoning this land and allowing for development would be a path to providing some new housing in the city. While the focus of rezoning should be on all potential future users under the R‐1 zoning designation, the narrative provided by Ron Clark Construction demonstrates both a high quality end product and an understanding that they are entering an existing neighborhood and an area with critical natural resources to protect. Recommendation Staff recommends approval of the requested amendment to the Zoning Map, changing the zoning designation for the proposed parcel as described in the land survey from Institutional Sub‐district I‐4, to Single Family Residential R‐1. Staff recommends approval of the requested amendment to the Future Land Use Map, changing the guided land use for the proposed parcel as described in the land survey from Parks & Natural Areas to Low Density Residential. The discussion started with process explanations and, PUD process, community engagement, and other input from watershed organizations and Met. Council. Chair Blum commented that it seems PUDs tend to maximize number of lots which causes concern for him on the size of lots proposed in this area. Campbell explained that a PUD can allow for more design flexibility, helps the City maintain wooded areas and greenspace. The City also changed the PUD requirements and new standards are in place to identify public amenities to be included in a PUD which allows the developer design flexibility. Campbell added he doesn’t feel a PUD only serves the developer. Commissioner Pockl asked if consideration for mature vegetation could be added to PUD requirements. Campbell responded that tree and landscape requirements would be required regardless of how the lots are established. The conversation moved on to discuss requirements for vegetation prior to these other approvals, hoping the property owner doesn’t clear cut prior to the landscaping considerations being in place. Commissioner Johnson expressed concern that the group is picking at the comp plan and how affordable and variety of housing is being factored into this plan. Campbell stated that the purchase agreement for the property may preclude affordable housing policies. However, the mixed‐income property policy requires new developments over a certain scale, make a percentage of the units available at a lower income value. In this case, the 7 units, do not meet the requirement for the policy. There are items in other chapters of the comp plan that can be addressed later in the proposal, at this point there are not enough details to say if these goals will be met. Blum stated that the Comp. Plan can be used to argue against the proposal as well and cited the open green space item. Pockl asked if the topography of the site limits development. Campbell responded that Engineering staff didn’t have an initial reaction when reviewing the proposal but details surrounding those specifics will be reviewed and discussed when this process is further along. Watershed and state agencies will be included in those conversations. City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 9 Chair Blum invited the applicant to speak. Ron Clark Construction, Applicant, has been working with the club for 6‐8 months and they feel strongly that re‐zoning that area to be R‐1 makes sense. The Club has been focused on making sure this benefits the City and the golf course and has had a holistic approach to this process. The design isn’t cookie cutter and the creation of a private road helps appeal from the course and helps the buffer to the road side. Chair Blum opened the public hearing at 10:04pm. Eric Boe 1023 Quebec Ave N I have lived here since 1993 and I’d like to add that all the homes in the area surrounding it are single‐ family detached homes. I think that’s an important detail. It’s good to hear in the plan they’d like to use a private road. One thing not mentioned, the four‐way intersection at Pennsylvania and Plymouth is offset. That creates limited visibility and any additional traffic and parked cars will add to safety concerns. I don’t want to see parking on this intersection or short driveways like over by Menards, I’d like to see a sidewalk added to the plan for added safety. Brent Behn 1300 Kelly Drive My concerns are regarding the term “low‐density” as it seems 7 large homes will be on a 2‐acre site and that appears to be fairly dense. This density level doesn’t fit in the community surrounding as the surrounding lots are bigger. I’m concerned with the rezoning continuing and more land being used for development in the golf course. Eric Brandt 7400 Plymouth Ave N We have a lot of parks in Golden Valley but I can’t think of another, separate 2.2‐acre wooded lot. I think we’re giving up a unique lot. Living here and looking at the wild‐life, they will all be impacted by clearing the trees. The private road sounds appealing but I can’t think of a single private road in Golden Valley that compares. Also, 7 homes on 2.2 acres is dense for this neighborhood and the proposed lot development would be an outlier. (Name inaudible) 1205 Pennsylvania Ave I’m also speaking on behalf of my neighbors. I’ve been privy to the plans and I want to indicate that I’m speaking a little out of context as I’m aware of the plans shared with golf course members. The private road is set to be on Pennsylvania Ave, the intersection is offset and congested. Our neighbors moved from an area near construction because it was impacting their quality of life and found this neighborhood mature and enjoyed the forest area across the street. The lot with trees is a gem as the previous caller mentioned. The cost associated with the development, the homes will not be on the City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 10 affordable side and while it may up our property values, it doesn’t seem that it would further Golden Valley’s objective to increase middle‐income housing. Chris Lowman 7440 Plymouth Ave We bought this house due to its location, we look right at the wooded lot. We are afraid the community that surrounds us will be taken away with this project. Additional traffic on this already busy corner makes us worried about the decrease in safety. We’re concerned about the lot sizes not matching the aesthetic of the neighborhood as well. The target market doesn’t seem to align with the market that wants to live in this neighborhood. My hope is that whatever decision is made, is the best one for the neighborhood and the city, not the developer. Commissioner Orloff stated that he feels more information on the ecological impacts will be needed. Campbell responded that any development will require removal of many trees and details around that will be navigated if this becomes a PUD. Commissioner Segelbaum thanked the callers and noted that many items will be addressed as the project moves forward. However, it seems that City Engineering staff do not think the addition of 7 homes will create unmanageable traffic. At this early stage, is parking or the offset intersection considered. Campbell responded that traffic volume is a principal concern, the other concerns will be addressed later as discussions around the private roadway occur. Brian Gieseke 1337 Kelly Drive I’d like to echo what I’ve already heard about the intersection, setbacks, the watershed, and traffic. The road is already narrow and there isn’t a stop sign for a few blocks so vehicle speeds increase. Parking will be an issue, especially over the winter and I’m concerned for further lot splitting if this area is zoned residential. The wooded area is special for our neighborhood and I am concerned for it to disappear. Blum urged everyone to utilize flexibility at this early stage and consider what’s most appropriate for the City and neighborhood here while being fair to the applicant. He referenced the 2040 Comprehensive Plan’s guide for open and green spaces. Blum stated he doesn’t support the applicant’s request. Pockl echoed those comments and said an appeal of Golden Valley are the green spaces and natural spaces. Pockl stated she doesn’t feel comfortable changing the zoning and land use at this point. Lynne Jensen 1039 Pennsylvania I’ve lived here 30 years and see a lot of wildlife coming from that area, eagles and owls nest in the trees proposed to be removed. The road to Winnetka on Plymouth is blocked and a lot of traffic is pushed to Pennsylvania. Traffic is already a problem on this street and particularly during rush hour. Additional traffic will also dissuade the active cycling community. City of Golden Valley Planning Commission Regular Meeting April 12, 2021 – 7 pm 11 Commissioner Johnson echoed Blum and Pockl’s and doesn’t see the benefit of taking the vibrant wooden greenspace and turning it in to 7 homes. Johnson is not in favor of changing the designation. Segelbaum followed up by saying the group is looking at seeing if the area is appropriate to convert from unused golf course space to housing. Caller concerns can be mitigated later in the negotiation process, it seems like there may already be a traffic issue. The PUD process will present an opportunity to help the existing areas. Johnson responded that the group has a responsibility to maintain greenspace. This plan drastically alters the landscape and he feels there will be more harm than good as a result. Blum responded that if they start the process now, momentum may take over and the project won’t turn out in the way the Commission intends on. Flexibility may occur now but things may not always turn out the way we want with that flexibility. Greenspace is valuable and so are lot sizes, once they’re given up, they’re gone. The group needs to do what it can to preserve those things. Chair Blum closed the public hearing at 10:45. Commissioner Brookins stated support for staff recommendation, feeling it’s appropriate for the area. MOTION made by Commissioner Pockl and seconded by Commissioner Johnson to deny the zoning designation amendment for the Northwest corner of 7001 Golden Valley Road. Staff took a roll call vote: Aye: Johnson, Pockl, Blum Nay: Brookins, Segelbaum Motion carries as stated. MOTION made by Commissioner Pockl and seconded by Commissioner Johnson to deny the land‐use amendment for the future land‐use map for the Northwest corner of 7001 Golden Valley Road. Staff took a roll call vote: Aye: Johnson, Pockl, Blum Nay: Brookins, Segelbaum Motion carries as stated. Televised portion of the meeting concluded at 10:53 pm 6.

Adjournment MOTION by Commissioner Pockl to adjourn, seconded by Commissioner Brookins, and approved unanimously. Meeting adjourned at 11:02 pm. ________________________________ Adam Brookins, Secretary ________________________________ Amie Kolesar, Planning Assistant 1 Date: April 26, 2021 To: Golden Valley Planning Commission From: Jason Zimmerman, Planning Manager Subject: Informal Public Hearing – Rezone Properties to Achieve Conformance with the 2040 Comprehensive Plan Summary Staff is requesting that 24 properties be considered for rezoning in order to come into conformance with the Future Land Use Map in the 2040 Comprehensive Plan. Background State statute requires that all zoning designations be updated to be consistent with the land uses identified in the Comprehensive Plan. A number of properties have already been rezoned, while others are awaiting further action such as the completion of the City’s Downtown Small Area Plan. Consideration of the current properties was paused while the Planning Commission and City Council adjusted the text of the zoning chapter of the City Code to allow rowhouses in the R‐2 zoning district. With that change completed, rezoning properties along the northern portions of Douglas Drive and Winnetka Avenue are now being revisited. Analysis The 24 properties under consideration represent two areas within the city. They both demonstrate a desire on the part of the City to intensify stretches of land along County roads by upzoning the residential densities allowed. The 2040 Comprehensive Plan put forward these land use designations as part of the approved Future Land Use Map. No development proposals are pending with the City at any of these locations. 2 Group 1 This group of 18 primarily single‐family residential properties along both sides of the northern portion of Douglas Drive was guided for Moderate Density use in the 2040 Comprehensive Plan. By rezoning to R‐2, duplexes and rowhouses would become options for these properties as they redevelop. All but one of these properties is currently zoned R‐1; a six‐unit development occupies a property zoned R‐3. Three lots zoned for single‐family use have legally nonconforming duplexes; two additional lots are vacant and are owned by the City. Address Current Zoning Current Use Proposed Zoning 2120 Douglas Drive North R‐3 Six‐unit development R‐2 2130 Douglas Drive North R‐1 Single‐family home R‐2 2150 Douglas Drive North R‐1 Single‐family home R‐2 2210 Douglas Drive North R‐1 Single‐family home R‐2 2230 Douglas Drive North R‐1 Single‐family home R‐2 2300 Douglas Drive North R‐1 Vacant R‐2 2310 Douglas Drive North R‐1 Single‐family home R‐2 2400 Douglas Drive North R‐1 Single‐family home R‐2 2410 Douglas Drive North R‐1 Single‐family home R‐2 2415 Douglas Drive North R‐1 Vacant R‐2 2420 Douglas Drive North R‐1 Duplex R‐2 2430 Douglas Drive North R‐1 Single‐family home R‐2 2501 Douglas Drive North R‐1 Single‐family home R‐2 2510 Douglas Drive North R‐1 Single‐family home R‐2 2511 Douglas Drive North R‐1 Single‐family home R‐2 2531 Douglas Drive North R‐1 Single‐family home R‐2 2551 Douglas Drive North R‐1 Duplex R‐2 6325 Medicine Lake Road R‐1 Duplex R‐2 3 At its regular meeting on August 10, 2020, the Planning Commission tabled consideration of a rezoning of the properties along the east side of Douglas Drive in light of pending zoning text amendments regarding rowhouses in the R‐2 zoning district. Given the new zoning language, rowhouses would be allowed on these properties, in addition to duplexes, should redevelopment occur. This would support the City’s goals of encouraging transit along arterial corridors and providing new types of housing. The existing single‐family homes would still be considered permitted uses under R‐2 zoning, so would not be impacted by this change. 4 Staff is recommending one deviation from the land use plan adopted as part of the 2040 Comprehensive Plan. The property at 2120 Douglas Drive zoned R‐3 currently houses six affordable units in two separate buildings. Rezoning this property to R‐2 would effectively lower the number of units that could be constructed and might be viewed as encouraging the displacement of affordable housing. Given how much additional thought has gone into the City’s housing plan since the Future Land Use map was draft four years ago, it is not inappropriate for the Planning Commission and City Council to consider this change. Staff supports a denial of the proposed rezoning to R‐2 and recommends allowing the property to remain zoned R‐3. The would also provide an appropriate transition between the R‐2 zoning district to the north and the Neighborhood Mixed Use zoning district to the south. Group 2 The west side of Winnetka Avenue North, between 23rd Avenue North and Medicine Lake Road, currently contains a vacant lot, four single‐family homes, a small office building, and the Golden Valley Cemetery. The 2040 Comprehensive Plan guided the office building and the adjacent single‐family home for Medium Density use, and the remaining four properties to the south for Moderate Density use. Address Current Zoning Current Use Proposed Zoning 2445 Winnetka Ave North Office Office building R‐3 2415 Winnetka Ave North R‐1 Single‐family home R‐3 2409 Winnetka Ave North R‐1 Single‐family home R‐2 2337 Winnetka Ave North R‐1 Single‐family home R‐2 2325 Winnetka Ave North R‐1 Single‐family home R‐2 PID 3011821110083 R‐1 Vacant R‐2 5 At its regular meeting on August 24, 2020, the Planning Commission considering a proposed rezoning of 2445 and 2415 Winnetka from Office and R‐1 to R‐3, as guided in the Comp Plan. At that point, testimony was provided by the owners of those properties in favor of the rezoning and by a handful of neighbors in opposition. It was noted that the current office use had been struggling in recent years and the property owner had previously asked the City to consider a rezoning to Commercial. This request was denied based on concerns regarding a number of potential uses that would be allowed under this zoning designation. The Planning Commission felt this property, along with the single‐family home to the south that has the same ownership, had the potential to provide a residential transition between the high density development to the east and single‐family neighborhoods to the west. This was the basis for the change to Medium Density Residential on the Future Land Use map. 6 Given the outstanding questions regarding the appropriateness of R‐3 zoning in this location, the Planning Commission tabled a decision to allow time for a conversation around rowhouses in the R‐2 zoning district to take place. Concerns voiced by neighbors centered on increased building height, traffic, and noise (see attached minutes of the August 24 meeting). The key aspects of the two zoning designations being considered are listed below: Medium Density Residential (R‐3) Zoning District Permitted Uses Duplexes Townhouses Multifamily buildings Senior and physical disability housing Conditional Uses Retail sales, restaurants, and professional offices on a ground floor with direct access to the street Density Range 12 units per acre or 17 units per acre with a CUP (up to three additional units per acre available through density bonuses) Senior/physical disability housing – 20 units per acre or 25 units per acre with a CUP (up to five additional units per acre available through density bonuses) Height Four stories or 48 feet Five stories or 60 feet for senior/physical disability housing with a CUP Moderate Density Residential (R‐2) Zoning District Permitted Uses Single‐family homes Duplexes Rowhouses Density Range Up to eight units per acre Height 28 feet to the midpoint of the highest pitched roof for single‐family homes and duplexes 35 feet maximum for rowhouses Similar to the points raised above about upzoning R‐1 properties to R‐2 along arterials, the other four properties under consideration would have the option to redevelop at a slightly higher density – either as duplexes or rowhouses. Should the City chose not to rezone any of these properties, an amendment to the Future Land Use Map would then be required with the Met Council – modifying the recently‐adopted 2040 Comprehensive Plan – in order to maintain consistency between guided land use and zoning. Recommended Action Staff recommends approval of an amendment to the Zoning Map to rezone the 17 of the 18 properties in Group 1 from Single‐Family Residential (R‐1) to Moderate Density Residential (R‐2). 7 Staff recommends denial of an amendment to rezone 2120 Douglas Drive North from Medium Density Residential (R‐3) to Moderate Density Residential (R‐2). Staff recommends approval of an amendment to rezone 2445 Winnetka Avenue North from Office to Medium Density Residential (R‐3) and 2415 Winnetka Avenue North from Single‐Family Residential (R‐1) to Medium Density Residential (R‐3). Staff recommends approval of an amendment to the Zoning Map to rezone four properties in Group 2 from Single‐Family Residential (R‐1) to Moderate Density Residential (R‐2).

In tandem with this action, the applicant also proposes to rezone the property from Office to Institutional (I‐1). Additionally, the applicant is proposing to expand the existing Planned Unit Development (PUD) consisting of Meadowbrook Elementary and the Davis Community Center to include 5300 Glenwood and fully incorporate it into the campus. Background and Existing Conditions 5300 Glenwood is a roughly one‐acre property containing a one‐story brick office building (though because of changes in topography on the site, it appears to be two stories with a walkout basement when viewed from the north). It was constructed in 1969 with a 6,400 square foot footprint and was owned by the Boy Scouts of American for many years before being sold and eventually purchased by the Hopkins School District in 2018. The property sits between Highway 100 and the Meadowbrook Elementary School campus. The entrance drive wraps around the building from Glenwood (to the south) to the parking lot to the north. A narrow secondary drive provides access to the east parking lot of Meadowbrook School. In 2019, after an amendment to the Meadowbrook PUD that allowed for an major expansion along the west side of the building, the school district instituted a new drop‐off/pick‐up circulation pattern that involved utilizing the long driveway and access drive at 5300 Glenwood in an effort to remove queueing from Glenwood and prevent congestion on the public right‐of‐way. These efforts have been successful and the school district is now looking to fully incorporate this property into the Meadowbrook campus. Required Process If the change in land use and zoning are both viewed favorably by the City Council, the Metropolitan Council would also be required to review and approve the land use change as it constitutes an amendment to the Future Land Use Map in the City’s 2040 Comprehensive Plan. The proposed PUD amendment, which would expand the boundary of the existing PUD and incorporate the 5300 Glenwood address, could move ahead for consideration by the City Council while this process plays out, though final approval of a new PUD Permit would need to wait for final review and approval by the Met Council. Neighborhood Notification The City’s adopted Neighborhood Notification Policy requires a neighborhood mailing be sent for changes to the Future Land Use or Zoning maps. Because the proposed Major PUD Amendment for this property required a neighborhood meeting be held, the three items were all addressed at one virtual meeting held on April 7. No neighbors attended the meeting and to date staff have received no comments on the land use change, the rezoning, or the PUD amendment. Staff Review The City Code does not set specific standards for changing a future land use designation, and the City Council – with the input of the Planning Commission – has a great deal of latitude in deciding if the request is consistent with the overall direction and vision of the Comprehensive Plan. In making 3 a determination, the City should take into account the land use descriptions outlined in the Comprehensive Plan as well as any potential impacts on the character of the area. For a baseline to this discussion, it is important to understand what both the existing and proposed land uses entail and the expectations placed on those land uses in the Comprehensive Plan. The 2040 Comprehensive Plan has the following description of the Office land use: This category includes offices for administrative, professional, and clerical services. This also includes medical or laboratory facilities where work is performed in a predominantly office setting. This land use is located near commercial, institutional, and high‐density residential areas and generates employment in the community. The Institutional ‐ Assembly land use is described as follows: This category includes education facilities at all levels, the cemetery, places of worship for all denominations, and miscellaneous religious installations. The applicant has indicated that the building at 5300 Glenwood would mostly likely be used for district offices or for special services educational programming. The office use would be consistent with either the Office or the Institutional ‐ Assembly land use. Both the exiting and the proposed uses appear to be compatible with the single‐family residential neighborhood to the south of Glenwood Avenue. Another important consideration for the reguiding and rezoning of the property is whether the planning actions makes sense in a broader context of addressing the concerns raised by residents when the Meadowbrook expansion was approved in 2018. At that point, the prospect of an increase in the on‐site queueing space for drop‐off/pick‐up vehicles was welcomed. Incorporating this property in to the school campus would allow that plan to come to fruition. Traffic It should be noted that the final use of the 5300 building has not yet been determined. Engineering staff are conducting a traffic study to evaluate the capacity of the site to accommodate additional vehicle trips – both at peak hours and at off‐peak hours. Any approval of a PUD amendment will include assurances that the future use be tempered, if necessary, to avoid exacerbating congestion issues. Comprehensive Plan Consistency Finally, staff reviewed the goals and policies of the Comprehensive Plan to help determine if this reguiding action follows the intent of the City’s central guiding plan. Based on the application materials, staff found the following goals and objectives to support the reguiding and incorporation of the site into the Meadowbrook campus. Land Use 1. Goal 2: Minimize Conflicts and Impacts Of Change ‐ Develop a regulatory framework designed to minimize potential conflicts between land uses. 4 a. Objective 2 – Support non‐residential growth opportunities while respecting adjacent properties b. Objective 2.1 – Promote Planned Unit Developments as a way to achieve zoning flexibility c. Transportation 1. Goal 2: Improve the Functionality and Safety of the Roadway Network – Improve mobility for efficient movement of people and goods on the local and regional roadway network. Improve safety for motorized and non‐motorized traffic a. Objective 4 – Use Travel Demand Management (TDM) practices and land use planning principles to reduce congestion and increase mobility b. Objective 4.2 – Require development proposals with potential for significant traffic impacts to prepare a traffic impact study or TDM plan and make improvements that mitigate impacts determined in the study Recommended Action Based on the findings above, staff recommends approval of the requested amendment to the Future Land Use Map, changing the guided land use for 5300 Glenwood Avenue from Office to Institutional ‐ Assembly.

In tandem with this action, the applicant also proposes to amend the City’s Future Land Use map to guide the property for Institutional ‐ Assembly use instead of the current guidance as Office. Additionally, the applicant is proposing to expand the existing Planned Unit Development (PUD) consisting of Meadowbrook Elementary and the Davis Community Center to include 5300 Glenwood and fully incorporate it into the campus. Background & Existing Conditions For details on the background of this rezoning request and the existing conditions of the site itself, please refer to the accompanying memo on the proposed change in guided land use. Staff Review The City Code does not set forth specific standards for changing a zoning designation, and the City Council – with the input of the Planning Commission – has a great deal of latitude in deciding if the request can be considered to be consistent with the broader zoning map for the City. In making a determination, the City should take into account the purpose of zoning as outlined in the City Code, which is “to regulate land use within the City, including the location, size, use, and height of buildings, the arrangement of buildings on lots, and the density of population within the City for the purpose of promoting the health, safety, order, convenience, and general welfare of all citizens of the City.” (Sec. 113‐2) This rezoning request seeks to change the sites zoning from Office to Institutional (I‐1). The purpose statements for both districts follow: Office Zoning The purpose of the Office Zoning District is to provide areas for the offices, clinics, day care centers, financial institutions, and other compatible uses that serve local and regional needs. The District fosters employment opportunities and encourages transitions between land uses. The District is not intended to serve as an area for the sale of or handling of goods, wares, merchandise, or commodities. Institutional The purpose of the Institutional Zoning District is to establish areas where both public and private institutional uses such as schools, hospitals, parks, golf courses, nursing homes, and public buildings may be located. Allowed Uses In the Office Zoning District, permitted uses include: 1. Offices 2. Clinics ‐ medical, dental, or optical 3. Financial institutions; and 4. Essential services, Class I. 3 Conditional uses include Adult Day Care Centers, Child Care Centers, Daytime Activity Centers for disabled people, Drive‐through Facilities for Financial Institutions, Heliports (accessory to an office), Limited Retail Service (accessory to an office), Recreational Facilities (accessory to an office) and Laboratories. The following principal uses are listed as permitted in the I‐1 Institutional Zoning Sub‐district: 1. Places of worship 2. Schools, public and parochial, excepting colleges, seminaries, and other institutions of higher education 3. Essential services, Class I; and 4. Seasonal farm produce sales. In addition to these four uses, Adult Day Care Centers, Child Care Centers, and Heliports are permitted in the I‐1 district by conditional use permit. Another important consideration is whether the rezoning is consistent with surrounding uses. Both office and institutional uses are considered to have lower external impacts on surrounding properties compared to industrial and commercial uses. That said, the conversion of the 5300 Glenwood property to a school use could mean additional traffic in the area. As noted in the associated memo related to the proposed land use change, a traffic study (currently underway) will assess the likelihood of any increase in congestion. In this case, the change in zoning to Institutional (I‐1) is consistent with the adjacent institutional properties west and complementary to the single‐family neighborhood to the south. Staff Findings The property under consideration is being rezoned to a use that would allow it to be fully incorporated into the Meadowbrook campus and complete the vision that was developed in 2018 when the school building was expanded. Given staff’s review, and weighing the opportunities and challenges provided by a change in zoning, the following findings from staff are made in support of rezoning the property in question to an Institutional (I‐1) designation: 1. The site is currently adjacent to a significant Institutional zoned property and would not be out of character with the surrounding neighborhood. 2. While more study will be needed to determine if any constraints need to be placed on the future uses of the property, Engineering staff is comfortable moving forward with the rezoning knowing that the pending PUD amendment can include conditions to limit any future impacts. 3. As noted in the accompanying memo on the site’s land use change, the use of this site for an expansion of the Meadowbrook campus fits with a number of the goals and objectives of the Comprehensive Plan. 4 Recommended Action Based on the findings above, staff recommends approval of the requested amendment to the Zoning Map, changing the zoning designation for 5300 Glenwood Avenue from Office to Institutional (I‐1). Attachments Excerpt of Zoning Map (1 page) Zoning Map 1 Date: April 26, 2021 To: Golden Valley Planning Commission From: Jason Zimmerman, Planning Manager Subject: Informal Public Hearing – Meadowbrook School PUD No. 90, Amendment #5 – 5430 and 5300 Glenwood Avenue Applicant: ISD #270 ‐ Hopkins School District Property owner: Same Zoning District: Institutional (I‐1) and Office Proposed PUD size: 13.08 acres Current use: School and office building Future land use: School Adjacent uses: Railroad/ponds (west), Residential and Church (south), Hwy 100 (north and east) 2020 aerial photo (Hennepin County) 2 Summary Hopkins Public Schools, represented by Neil Tessier, is applying for a Major Planned Unit Development (PUD) Amendment in order to expand the boundary of the PUD and to incorporate additional land area currently addressed as 5300 Glenwood Avenue. This expansion would allow for the completion of a traffic control plan initiated as part of Amendment #4 in 2018 as well as provide future space for district offices or special services educational programming. Background PUD No. 90 was adopted by the City Council on December 19, 2000. The PUD was established to allow the City and the School District to build the Davis Community Center following the relocation of Turners Crossroad and Xenia Avenue. The first amendment to the PUD was approved in May 2012 to allow a small addition to the building. The second amendment, approved in November 2012, allowed for modifications to be made to the parking area. A third amendment was approved in October 2013 to consolidate the Meadowbrook School parcel, the Davis Community Center parcel, and the former Crisis Nursery parcel (which was connected to the main school building via a newly constructed tunnel). The latest amendment (number five) was approved in May 2018. This modification allowed for the addition of nine new classrooms on the west side of the building and modified both the east and west parking lots as well as right‐of‐ way improvements with new turn lanes to improve traffic flow. Existing Conditions The size of the current Meadowbrook PUD is roughly 10.5 acres. It is bounded on the west by Turners Crossroad North, on the east by Highway 100, and to the south by Glenwood Avenue. An office building sits adjacent to the PUD to the east at 5300 Glenwood Avenue. This is the property that would be included in the PUD if it is expanded. The entire Meadowbrook School site is guided for Institutional use in the Comprehensive Plan and is zoned Institutional (I‐1), the category reserved for schools and places of worship. There are currently four access points to the school campus—two on Turners Crossroad and two on Glenwood Avenue. The northern driveway on Turners provides access to the loading and unloading area for buses. The southern driveway provides access to a small circular drive and parking area which is utilized for student drop‐offs and pick‐ups for the school and the community center. Along Glenwood, the western driveway is limited to exiting the site. All vehicles entering the site (teachers, staff, and parents) currently utilize an eastern driveway that loops through the 5300 Glenwood property and threads its way through an upper and lower parking area. Enrollment at the school is capped at 890 students through a condition of the existing PUD Permit. Proposal In response to feedback from the City as part of Amendment #4, the Hopkins School District purchased 5300 Glenwood Avenue and has been testing a new circulation pattern for the eastern parking lot. The new proposal would officially incorporate this property into the PUD. Separately, 3 the school district has submitted applications to change the land use and the zoning of this property. In addition to 5300 Glenwood, the expansion of the PUD would also include land along Highway 100, along Glenwood Avenue, and near the exit ramp from Highway 100 onto Glenwood. This excess right‐of‐way is not needed by MnDOT, Hennepin County, or the City and would help to ensure all school uses (such as the running track) are located on school grounds. The City supports transferring responsibility for some existing infrastructure to the school as part of this arrangement. As part of this project, the parking lot at 5300 would be improved to provide a more direct circulation pattern and better capture and treat stormwater runoff. New lighting and landscaping around the parking lot would also be provided. The existing narrow drive that connects the two properties would be widened and improved to create a direct route for queueing vehicles. The northeast corner of the existing east Meadowbrook lot would also be expanded slightly in order to recapture some of the parking stalls lost during this realignment. Overall, between the two parking lots, the parking count would drop from 211 to 197. As a carry‐over from the last PUD amendment, the school has also provided a letter confirming the process for verifying student enrollment annually as well as a description of the site logistics for drop‐offs and pick‐ups of students. Finally, the applicant has provided a deposit for the City’s traffic engineering consultant to evaluate the current traffic levels and ensure that future use of the 5300 building by the school district will not generate congestion on Glenwood Avenue. Neighborhood Notification The City’s adopted Neighborhood Notification Policy requires a neighborhood meeting to share any proposal for a Major PUD Amendment. A virtual meeting that addressed the PUD amendment, the proposed land use change, and the rezoning was held on April 7. No neighbors attended the meeting and to date staff have received no comments. Evaluation Land Use and Zoning Considerations As a PUD, the City can offer flexibility from the regular zoning requirements in order to achieve a better development. With the inclusion of 5300 Glenwood Avenue and the adjacent excess rights‐ of‐way along Highway 100 and Glenwood Avenue, very little additional flexibility is being requested on the part of the City. The primary modification would be the expansion of the drive between the Meadowbrook campus and the 5300 parcel. This paved connection would not be allowed outside of a PUD, but as part of the development provides an extended circulation pattern that is a benefit to the City in that it keeps vehicles from queueing on Glenwood Avenue at peak drop‐off and pick‐ up times. 4 Additionally, some interior parking setbacks would continue to be less that what the zoning requirements would be for institutional‐zoned properties (25 feet), but because these represent a setback internal to the PUD there are no impacts to surrounding property owners. Changes to the amounts of impervious surfaces (32.09% without the 5300 property and 32.78% with it included) and open space (44.86% without the 5300 property and 44.17% with it included) are also negligible. In summary, the inclusion of the 5300 Glenwood property has no discernable impact on the overall conformance to the usual Institutional requirements, has great benefit to those traveling along Glenwood Avenue, and requires only one primary concession in terms of zoning flexibility on the part of the City. Traffic A major impetus for the inclusion of the 5300 Glenwood property into the Meadowbrook PUD is the ability to relieve congestion on Glenwood Avenue by increasing the length of the queueing lanes. The concept of utilizing the long driveway at 5300 and improving the existing internal connection between the two properties was supported by the Planning Commission and City Council during the review process for Amendment #4 in 2018. An informal test of this arrangement has shown to remove traffic queues from Glenwood Avenue during regular conditions – though it should be noted that traffic congestion did occur during the initial return to school phase of the 2020‐21 school year as many parents avoided sending their children to/from school on buses. Operations have since been optimized and the problems have been alleviated. In order to ensure the future use by the school district of the 5300 building does not add to traffic concerns, a traffic study is currently underway to evaluate how much capacity might exist during peak drop‐off and pick‐up times. Should the results of this study indicate likely problems, the City retains the right to curtail the use or the hours of operation at this location. Stormwater New stormwater management in the form of an underground treatment area would be constructed under the parking lot at 5300 Glenwood, along with improvements to other surrounding infrastructure. Additional details and requirements are included in the Engineering comments below. Lighting New lighting for the parking lot at 5300 and the edge of the east parking lot for Meadowbrook is proposed as part of the improvements associated with this PUD amendment. As submitted, some lighting levels on the plans exceed the allowances of the City’s “dark skies” outdoor lighting standards. Adjustments will be required prior to the approval of the PUD Permit by the City Council. 5 Landscaping The proposed landscaping plans primarily focus on the 5300 Glenwood property, but do include some plantings along the eastern edge of the current Meadowbrook campus. Staff review confirms the required one‐for‐one replacement of planted and significant trees and shrubs has been met, with 16 new trees, 20 new shrubs, and 15 new perennials replacing 12 identified tree removals. Additional review and possible adjustments to species or locations will be conducted as part of the Tree and Landscape Permit process near the end of construction. Platting In addition to replatting the two properties in order to consolidate them into one PUD, additional land is intended to be incorporated by obtaining areas along Highway 100, along Glenwood Avenue, and near the exit ramp from Highway 100 (including the existing driveway to 5300 Glenwood). The school is also required to provide new walkway easements for a public trail along Glenwood Ave that veers onto its property. Enrollment and Operations In response to conditions placed on Meadowbrook as part of Amendment #4, the school district has provided confirmation that enrollment continues to remain below the maximum allowed level of 890 students and has also outlined a process for sharing this information with the City annually. Engineering and Fire Safety Considerations As is standard practice for development proposals, plans were reviewed by the City’s Engineering staff and the following notes were provided: The school is required to provide walkway easements, to be recorded as separate documents, for any trail along Glenwood that is within the school property. The school should provide exhibits and legal description (two feet north of trail edge) and the City will prepare documents. This was a condition of previous PUD approvals for this site. The ROW layout is subject to the review and approval of Hennepin County and MnDOT. City will vacate any interest it has in the MnDOT turnback area over a portion of the east driveway entrance and along the east side of PUD, with the exception that drainage and utility easements will be retained (or must be dedicated on the plat) for any areas with City utilities present. Any and all infrastructure within this vacation area would be owned and maintained by the school district and included in the maintenance agreement executed between the City and the school. The proposed project requires BCWMC review of the erosion and sediment control plan. The City will need evidence of BCWMC approval before City permits are issued. The proposal requires plat review by MnDOT and Hennepin County. The stormwater report and plan require review and a permit application from MnDOT for changes proposed to the storm sewer/stormwater system that drains to MnDOT’s system within the Highway 100 corridor. The City will need evidence of MnDOT review and permit issuance before City permits are issued. 6 If construction dewatering and pumping is required, the City will need to see evidence of permits and approvals from MnDNR and other applicable agencies before City permits are issued. The existing stormwater maintenance agreement for the Meadowbrook site will need to be updated as part of this PUD Amendment. The City will prepare all documents for review and signatures. The district’s existing chloride management plan for Meadowbrook will need to be updated and included as part of this maintenance agreement. The Fire Department reviewed this proposal for adequate emergency access and public safety requirements and had no concerns. Anticipated Development Timeline Construction is planned to take place in June through August of 2020. Future interior remodeling of the 5300 Glenwood building would likely take place at a future date once the final use has been determined. Findings In order approve an amendment to a PUD, the City must be able to make certain findings as outlined in Section 113‐123, Subd. (c)(2) of the City Code. These findings, along with staff responses, are listed below: Quality Site Planning. The PUD plan must be tailored to the specific characteristics of the site and achieve a higher quality of site planning and design than generally expected under conventional provisions of the zoning chapter. The PUD amendment is tailored to the specific characteristics of the site by providing a beneficial circulation plan that ensures vehicles are queueing off of the public right‐of‐way to avoid creating back‐ups and congestion on Glenwood Avenue. Other improvements to the parking lot provide a needed update to older infrastructure. Preservation. The PUD plan must preserve and protect substantial desirable portions of the site’s characteristics, open space, and sensitive environmental features including steep slopes, trees, scenic views, creeks, wetlands, and open waters. Minimal tree removal required as part of the project is mitigated through replanting. No sensitive site features are impacted. Efficient; Effective. The PUD plan must include efficient and effective use of the land (which includes preservation). The proposed amendment would utilize land efficiently by consolidating nearby excess right‐ of‐way and opening up an existing building for additional school operations. Consistency. The PUD plan must result in development that is compatible with adjacent uses and consistent with the Comprehensive Plan and redevelopment plans and goals. The proposal is consistent with the current use of the existing PUD and there are no known impacts to the surrounding residential neighborhood. The proposal is consistent with the City’s Comprehensive Plan, which calls for the support of non‐residential growth opportunities and utilizing the PUD process as a way to achieve zoning flexibility. 7 General Health. The PUD plan must be consistent with preserving and improving the general health, safety, and welfare of the people of the city. The PUD amendment would improve general health by providing water quality improvements to the Sweeney Lake sub‐watershed through new stormwater management infrastructure, and would improve safety and welfare by ensuring continued improvements to the traffic flow on Glenwood Avenue. Meets Requirements. The PUD plan must meet the intent and purpose provisions of Section 113‐123 as well as all other provisions. The creativity and flexibility provided under the PUD section of the Zoning Code allows for the coordinated use of a long driveway across two properties in order to provide congestion reduction. The PUD amendment meets the Intent and Purpose provision of the City Code in that it creates a public benefit in exchange for this flexibility. Recommendation Based on review of the materials submitted and the findings above, staff recommends approval of Amendment #5 to Meadowbrook School PUD No. 90, subject to the following conditions: 1. The photometric plans must be updated to conform to City standards for lighting levels and shall be reviewed and approved by staff prior to the issuance of building permits. 2. Information on enrollment, staffing, and program activities shall be provided to the City annually by October 1st or more frequently if changes are proposed or anticipated. Additional enrollment, or changes to staffing or programming, may only occur in concert with the construction of additional comprehensive traffic management solutions. 3. The City reserves the right to curtail certain uses or hours of operation for the 5300 Glenwood Avenue building pending the results of the ongoing traffic study in order to manage on Glenwood Avenue. 4. A financial guarantee shall be submitted to the City to ensure all title work is completed and the final plat is recorded with Hennepin County. 5. Walkway easements for any trail along Glenwood that is within the school property shall be recorded as separate documents. The school shall provide exhibits and legal description (two feet north of trail edge) and the City will prepare documents. 6. The City will vacate any interest it has in the MnDOT turnback area over a portion of the east driveway entrance and along the east side of PUD, with the exception that drainage and utility easements will be retained (or must be dedicated on the plat) for any areas with City utilities present. Any and all infrastructure within this vacation area would be owned and maintained by the school district and included in the maintenance agreement executed between the City and the school. 7. The existing stormwater maintenance agreement for the Meadowbrook site shall be updated as part of this PUD Amendment. The City will prepare all documents for review and signatures. The district’s existing chloride management plan for Meadowbrook shall be updated and included as part of this maintenance agreement. This approval is subject to all other state, federal, and local ordinances, regulations, or laws with authority over this development. 8 Attachments Project Narrative (3 pages) Student Enrollment and Site Logistics Letter (2 pages) Plans received March 2, 2021, and updated April 16, 2021 (13 pages) SAFEngineering Site and Athletic Facility Engineering, PLLC 3200 122nd Avenue NE Blaine, MN 55449 March 17, 2021 Mr. Jason Zimmerman Planning Manager City of Golden Valley 7800 Golden Valley Road Golden Valley, MN 55427 RE: ISD #270 - Meadowbrook ES Parking Lot Improvements - PUD Narrative Letter In accordance with the City of Golden Valley PUD Major Amendment requirements, we are pleased to provide the following narrative per your request for additional information letter dated March 12, 2021. PUD NARRATIVE 1. The City of Golden Valley PUD Section of the City Code, Section 113-123. A. The current zoning of the eastern portion of the property is Business. The School District purchased the eastern portion of the property, formerly the Boy Scout building and other business operations, and would like to change the zoning to Institutional. B. The existing school owned property, western portion of the site, has two buildings connected together with an underground tunnel. This portion of the property is zoned Institutional. Both properties will be combined into one parcel, with dedicated easements for utilities, paths and wetlands. The final plat and zoning will be Institutional. C. The new site plans and future use of the newly acquired building meet the Intent and Purposes of the PUD. a. Quality Site Planning: The plans have been specifically tailored to provide maximum auto traffic queuing to improve the characteristics of the site. Significant storm water systems have been designed to improve water quality. Landscaping has been designed to improve the aesthetics of the site. New site lighting has been designed to improve the safety of the site. b. Preservation: The new design minimizes the impact to the natural landscape. A minimum number of trees were removed and will be replaced with better quality trees and in locations to improve the aesthetics of the site as well as additional landscaping. Significant storm water systems have been designed to improve water quality. SAFEngineering Site and Athletic Facility Engineering, PLLC 3200 122nd Avenue NE Blaine, MN 55449 c. Efficient, Effective: The new design minimizes the impact to the natural landscape. A minimum number of trees were removed and will be replaced with better quality trees and in locations to improve the aesthetics of the site as well as additional landscaping. The new footprint of the hard surfaced areas was minimized and closely matched the existing hard surfaced areas. d. Consistency: The new use of the building is more compatible with the overall site. The newly acquired building will be educational based and fits in better than the previously Building zoning and usage by the previous owner. The new Institutional zoning is more consistent with the other portion of the property. e. General Health: The new use of the building will definitely improve the safety of the property and City. The new expanded drive lanes will permit more vehicles on site to significantly increase the queue for morning drop off and afternoon pick-up of students. This will remove cars from the City streets, creating a safer environment for the residents of Golden Valley. e. General Health: The PUD plan meets the Intent and Purpose of all required sections of PUD Section 113-123. The rational for combining the properties into one is for the benefit of the community and the School District to provide for an exceptional educational facility to serve the needs of the residents of the City of Golden Valley. D. The overall concept for the School District property is multi-faceted. The main purpose of the site is for the educational benefit of the students and community of the City of Golden Valley who attend the many functions of the property. The properties main buildings are used for elementary school education. The other buildings provide daycare as well as educational services. There is a community center within the main building utilized for a wide variety of educational opportunities for all members of the community. The newly acquired building will be renovated. The intent of the renovation is unknown at this time. However, it will be utilized for either School District offices, special services educational programming or a combination of both. 2. The existing footprint for the western portion of the property is as follows: A. Main Building: 109,000 Square Feet B. Secondary Building: 8,000 Square Feet C. New Building: 6,400 Square Feet D.

BAYFILTER MAINTENANCE THE BAYFILTER SYSTEM REQUIRES PERIODIC MAINTENANCE TO CONTINUE OPERATING AT ITS PEAK EFFICIENCY DESIGN. THE MAINTENANCE PROCESS COMPRISES THE REMOVAL AND REPLACEMENT OF EACH BAYFILTER CARTRIDGE AND THE CLEANING OF THE VAULT OR MANHOLE WITH A VACUUM TRUCK. FOR BEST RESULTS, BAYFILTER MAINTENANCE SHOULD BE PERFORMED BY A CERTIFIED MAINTENANCE CONTRACTOR. A QUICK CALL TO AN ADS ENGINEER OR CUSTOMER SERVICE REPRESENTATIVE WILL PROVIDE YOU WITH A LIST OF RELIABLE CONTRACTORS IN YOUR AREA. WHEN BAYFILTER IS INITIALLY INSTALLED, WE RECOMMEND THAT AN INSPECTION BE PERFORMED ON THE SYSTEM IN THE FIRST SIX (6) MONTHS. AFTER THAT, THE INSPECTION CYCLE TYPICALLY FALLS INTO A BIANNUAL PATTERN GIVEN NORMAL STORM OCCURRENCE AND ACTUAL SOLIDS LOADS. WHEN BAYFILTER EXHIBITS FLOWS BELOW DESIGN LEVELS, THE SYSTEM SHOULD BE INSPECTED AND MAINTAINED AS SOON AS PRACTICAL. REPLACING A BAYFILTER CARTRIDGE SHOULD BE CONSIDERED AT OR ABOVE THE LEVEL OF THE MANIFOLD. MAINTENANCE PROCEDURES 1. REMOVE THE MANHOLE COVERS AND OPEN ALL ACCESS HATCHES. 2. BEFORE ENTERING THE SYSTEM MAKE SURE THE AIR IS SAFE PER OSHA STANDARDS OR USE A BREATHING APPARATUS. USE LOW O2, HIGH CO, OR OTHER APPLICABLE WARNING DEVICES PER REGULATORY REQUIREMENTS. 3. USING A VACUUM TRUCK, REMOVE ANY LIQUID AND SEDIMENTS THAT CAN BE REMOVED PRIOR TO ENTRY. 4. USING A SMALL LIFT OR THE BOOM OF THE VACUUM TRUCK, REMOVE THE USED CARTRIDGES BY LIFTING THEM OUT. 5. ANY CARTRIDGES THAT CANNOT BE READILY LIFTED CAN BE EASILY SLID ALONG THE FLOOR TO A LOCATION THEY CAN BE LIFTED VIA A BOOM LIFT. 6. WHEN ALL THE CARTRIDGES HAVE BEEN REMOVED, IT IS NOW PRACTICAL TO REMOVE THE BALANCE OF THE SOLIDS AND WATER. LOOSEN THE STAINLESS CLAMPS ON THE FERNCO COUPLINGS FOR THE MANIFOLD AND REMOVE THE DRAINPIPES AS WELL. CAREFULLY CAP THE MANIFOLD AND THE FERNCO'S AND RINSE THE FLOOR, WASHING AWAY THE BALANCE OF ANY REMAINING COLLECTED SOLIDS. 7. CLEAN THE MANIFOLD PIPES, INSPECT, AND REINSTALL. 8. INSTALL THE EXCHANGE CARTRIDGES AND CLOSE ALL COVERS. 9. THE USED CARTRIDGES MUST BE SENT BACK TO ADS FOR EXCHANGE/RECYCLING AND CREDIT ON UNDAMAGED UNITS. BAYFILTER INSTALLATION NOTES 1. CONTACT UTILITY LOCATOR TO MARK ANY NEARBY UNDERGROUND UTILITIES AND MAKE SURE IT IS SAFE TO EXCAVATE. 2. REFERENCE THE SITE PLAN AND STAKE OUT THE LOCATION OF THE BAYFILTER VAULT. 3. EXCAVATE THE HOLE, PROVIDING ANY SHEETING AND SHORING NECESSARY TO COMPLY WITH ALL FEDERAL, STATE AND LOCAL SAFETY REGULATIONS. 4. LEVEL THE SUB–GRADE TO THE PROPER ELEVATION. VERIFY THE ELEVATION AGAINST THE MANHOLE DIMENSIONS, THE INVERT ELEVATIONS, AND THE SITE PLANS. ADJUST THE BASE AGGREGATE, IF NECESSARY. 5. HAVE THE SOIL BEARING CAPACITY VERIFIED BY A LICENSED/ENGINEER FOR THE REQUIRED LOAD BEARING CAPACITY. ON SOLID SUB–GRADE, SET THE FIRST SECTION OF THE BAYFILTER PRE–CAST VAULT. 6. CHECK THE LEVEL AND ELEVATION OF THE FIRST SECTION TO ENSURE IT IS CORRECT BEFORE ADDING ANY RISER SECTIONS. 7. IF ADDITIONAL SECTION(S) ARE REQUIRED, ADD A WATERTIGHT SEAL TO THE FIRST SECTION OF THE BAYFILTER VAULT. SET ADDITIONAL SECTION(S) OF THE VAULT, ADDING A WATERTIGHT SEAL TO EACH JOINT. 8. INSTALL THE PVC OUTLET MANIFOLD. 9. INSTALL THE PVC OUTLET PIPE IN BAYFILTER VAULT. 10. INSTALL THE INLET PIPE TO THE BAYFILTER VAULT. 11. AFTER THE SITE IS STABILIZED, REMOVE ANY ACCUMULATED SEDIMENT OR DEBRIS FROM THE VAULT AND INSTALL THE FLOW DISKS, DRAINDOWN MODULES (IF APPLICABLE), AND THE BAYFILTER CARTRIDGES. 12. PLACE FULL SET OF HOLD DOWN BARS AND BRACKETS INTO PLACE. 0015'30'SHEET OFDATE:PROJECT #:DRAWN:CHECKED:THIS DRAWING HAS BEEN PREPARED BASED ON INFORMATION PROVIDED TO ADS UNDER THE DIRECTION OF THE SITE DESIGN ENGINEER OR OTHER PROJECT REPRESENTATIVE.
