Attachments: Draft Minutes 4 1 Proposed Minutes September 6, 2023 Proposed Minutes Planning Commission Meeting September 6, 2023 Chair Boo called a Meeting of the Plymouth Planning Commission to order at 7:00 p.m. in the Council Chambers of City Hall, 3400 Plymouth Boulevard, on September 6, 2023. COMMISSIONERS PRESENT: Chair Michael Boo, Bill Wixon, Marc Anderson, Neha Markanda, and Josh Fowler COMMISSIONERS ABSENT: Jennifer Jerulle and Julie Olson STAFF PRESENT: Planning and Development Manager Chloe McGuire, Senior Planner Shawn Drill, and City Council Liaison Julie Pointner Chair Boo led the Pledge of Allegiance. Call to Order Approval of Agenda Motion was made by Commissioner Fowler and seconded by Commissioner Anderson to approve the agenda. With all Commissioners voting in favor, the motion carried. Consent Agenda (4.1) Planning Commission minutes from meeting held on August 16, 2023. Motion was made by Commissioner Fowler and seconded by Commissioner Wixon to approve the consent agenda. With all Commissioners voting in favor, the motion carried. Public Hearings (5.1) Request for comprehensive plan amendment by Scannell Properties LLC to reguide roughly 75 acres to MXD (mixed use) for property located at 13001 County Road 10 (2023- 052). Senior Planner Drill presented the staff report. 5 2 Proposed Minutes September 6, 2023 Commissioner Anderson referenced the statement that there would not be an impact on traffic, utilities, etc. He asked if that was determined by the Alternative Urban Areawide Review (AUAR) which was presented to and approved by the city council. Senior Planner Drill confirmed that the AUAR was approved by the council in July and included the traffic and utility studies. He commented that typically a large-scale development such as this would include an environmental assessment worksheet, but the alternative was to complete the AUAR. He explained that the AUAR would need to be revisited and updated every five years. Commissioner Wixon asked the number of multi-family housing units. Senior Planner Drill replied that the applicant is still determining the number of units that they would propose but noted that could range from roughly 700 to 1,000 units or more. Commissioner Wixon commented that the schools would be considerably impacted by that number of people and asked if that has been considered. Senior Planner Drill replied that the school district is aware of the potential development and noted that as a part of the AUAR process the schools commented that they do not have concerns. Commissioner Markanda asked if the primary component would be housing compared to commercial/retail. Senior Planner Drill replied that in terms of building square footage, the apartments would be the largest, but noted that in terms of land area housing would be less than 50 percent of the total land area. Commissioner Anderson asked if it would be possible that the applicant could come back with just one use, or whether it would be a requirement to have multiple uses. Senior Planner Drill replied that the requested MXD guiding requires a mix of uses. Chair Boo asked for input on whether there would be any concerns removing this land from CO (commercial office) and placing it under MXD (mixed use). Senior Planner Drill replied that the property is currently guided for office uses. He provided details on the amount of land that would remain in the CO guiding category after this change. He stated that there would not be a negative impact in making this reguiding change. Chair Boo invited the applicant to address the commission. Chair Boo introduced Andy Bollig, Roers Companies, and Dan Salzer, Scannell Properties, who represent the applicants for this proposal. Mr. Bollig thanked staff for their work on this matter, noting that they have been doing a lot of work to identify tenants for the property as they have many interested parties. He commented that they are excited to bring a mix of users to the site with preservation of natural space as well. 6 3 Proposed Minutes September 6, 2023 Commissioner Anderson asked how optimistic the applicant is about being able to secure the desired tenants and buyers. Mr. Bollig replied that they are very optimistic, recognizing that this is a long-term partnership that will not happen overnight. He stated that Roers will be doing the multi-family development and will begin to bring in requests for next year. He commented that they want to find the highest and best use for the property. Commissioner Anderson referenced the area along I-494, noting that previous plans identified warehouse or office/warehouse. He stated that is now identified as med tech and asked if that is simply a change in terminology or whether that is a different use. Mr. Salzer replied that a variety of users could fall under that use. He commented that it would be more of a corporate campus type user, and they are excited about the interest that has been expressed. Chair Boo asked for details on the timeline of development. Mr. Bollig replied that it would be completed in phases, with changes beginning on the site next year, but recognized that it would be a year-long process as the right users come forward. Commissioner Wixon asked if the Prudential office building would be removed and whether that would be done early in the process. Mr. Bollig confirmed both of those statements to be correct. Commissioner Markanda commented that in a post-COVID world, many corporations have scaled back on the need for a large corporate office. She asked the mitigation plan in the case that type of clientele is not there for the med tech space. Mr. Salzer commented that space would not necessarily be just office and would be a combination of office, lab, and R & D space. He agreed that the need for only office space has gone away. Commissioner Fowler asked for the order of the phasing, recognizing that would be somewhat market dependent. He asked for details on the process for review by staff in terms of mixed-use development if the residential development were to come first. Mr. Salzer stated that the next step would be preliminary plat and a zoning application which would identify certain areas for the different uses. He commented that if everything goes well, he would anticipate breaking ground on a few projects in the spring. Senior Planner Drill noted that the PUD general plan would identify the allowed uses and if the applicant desired to change something after that point, it would require an amendment with another public hearing. Chair Boo opened the public hearing. 7 4 Proposed Minutes September 6, 2023 Chair Boo introduced Rob Hastings, 5830 Oakview Lane N, who stated that he has recently noticed a lot more traffic because of the work being done on Bass Lake Road. He was concerned with additional traffic from this development and suggested that perhaps there could be a dead end in his neighborhood to prevent cut through traffic. He noted that perhaps there could still be a pedestrian connection through. Chair Boo introduced Jim and Lisa Pavich, 5805 Rosewood Ln N, who had questions about the increased traffic that would result from that number of residential units. He raised concerns with health and safety as well as noise. Chair Boo introduced Amy Marie Lemanski, 5955 Wedgewood Lane N, who stated that she is excited about this project. She commented that although a grocery store would be a lovely idea, there are already many different grocery options within a five-mile radius. She asked for details on the housing and whether it would be apartments and/or affordable. Chair Boo introduced Elaine Anderson, 16905 49th Place N, who implored the city and planners to consider walkability and human friendliness seriously. She commented that the layout seems friendly for parking and vehicles. She commented on the lack of walkability between the movie theater and nearby restaurant and did not want to see that pattern repeated. She encouraged parking on the outside with the buildings and walkability on the inside. Chair Boo introduced Deb Peterson, 13445 60th Place N, who expressed concern with the traffic. She noted that people often do not stop for the pedestrian crossings and requested a pedestrian stoplight which would ensure vehicles stop to allow crossing. Chair Boo introduced Andy Snope, 200 Nathan Lane, who stated that he represents the electrical worker ’s union. He commented that several people are present from the construction industry. He supported the proposal and believed it to be a good use for the site with mixed use. He recognized that the final plans are not yet before the commission but believed that this would be a good use of a tired property. He noted that this would be a great place for future and current residents to live, shop, work and recreate. He noted that this development would increase the tax base while also creating jobs. He stated that the developer would also request tax dollars to help with the improvement. He commented that he believes that this would be a good use of tax dollars to create the end result. He stated that with larger projects sometimes come issues with wages and craftsmanship and therefore asked that there is assurance that workers are paid fairly for the construction portion of the project and that the craftsmanship would be at the required level as well. He asked what the PUD would be used for if this were to be rezoned mixed use. Chair Boo closed the public hearing. Senior Planner Drill commented that a traffic study has been completed based on this plan and the highest use of the site and it was determined that this site could accommodate the traffic with some improvements. He stated that he could provide a copy of the study to anyone that is interested. He stated that the development contract would address access routes for construction traffic. He commented that there are certain warrants for traffic lights and other traffic measures and, therefore, they would need to investigate further about the pedestrian crossing concerns raised by the resident tonight. 8 5 Proposed Minutes September 6, 2023 Chair Boo asked the applicant about thoughts on a grocery store after the comments made tonight. Mr. Bollig replied that the likelihood of a grocer is strong as they have multiple companies interested. He noted that grocers go through an extensive market study to identify locations and there is demand for another grocer in this area. He stated that they would include affordable housing in line with the city’s affordable housing policy. Chair Boo asked how the city addresses the concern with walkability. Senior Planner Drill commented that the thought is to create a development where people can live, work, play and shop without getting into a vehicle. He commented that there would be an extensive trail system with sidewalks along public streets and a city trail and potentially boardwalk through the central portion of the pond and patterned crosswalks. He noted that the multi-family housing would have underground parking. Planning and Development Manager McGuire commented that when more specific site design comes forward, the commission would have the opportunity to review that and provide input. She noted that the goal is for people to park and then walk throughout the site, but recognized that people would most likely want to drive to a grocery store. Chair Boo asked how the city would address the concerns with wages for contractors. Senior Planner Drill stated that he would have to look into that. He noted that money would not be taken out of the city’s tax coffers, but rather, any financial aid would be provided through tax increment financing (TIF). He stated that perhaps they could address the concerns in the TIF development agreement. Mr. Bollig commented that they would be happy to update the industry numbers used in their narrative. He stated that many of the tenants would be building their own projects and they would be happy to have those conversations. Chair Boo recognized that a PUD provides flexibility but also ensures that the city able to gain the desired amenities and type of development as well. Commissioner Anderson recognized the concern with traffic raised tonight. He stated that Prudential existed on the site with 450,000 square feet of office space and a huge parking lot. He asked if there would be a comparison to that use versus the proposed use. Senior Planner Drill commented that the AUAR and traffic study are posted on the city website for those interested. He confirmed that the traffic study compared the previous development to the development proposed and also looked at it from the perspective of full site development. He stated that a traffic study would be included with the PUD review. He stated that the mitigation measures identified in the AUAR have been adopted by the council and would need to be implemented in future plans submitted by the developer. Chair Boo recognized that this is very early in the development process, noting that this change would be for reguiding the site from CO (commercial office) to MXD (mixed use). 9 6 Proposed Minutes September 6, 2023 Commissioner Anderson commented that it is refreshing to see just the comprehensive plan amendment at this time, as that breaks down the review process and allows them to focus on the individual steps as they move forward. He noted that this would also refresh the site. He agreed that changing the use of the site would make sense and mixed use would provide the city with a lot of control. He stated that a grocery use would be market dependent and if there are 1,000 housing units, that would provide demand for a grocer. Commissioner Markanda commented that this is a great layout and change is inevitable. She requested that the developers keep safety and traffic in the forefront, as those will dictate whether the site will be successful. Commissioner Fowler commented that this is an extremely appropriate site for mixed use development, and a more appropriate use of the site than office development. He appreciated the concerns related to traffic as he commutes near this site daily. He hoped that the metro link bus extension would help and noted that the phased development plan would also assist in traffic management. He commented that walkability is a big concern as this moves forward, noting that this has the opportunity to be a well-connected community rather than a field of parking lots. Motion was made by Commissioner Anderson and seconded by Commissioner Markanda to recommend approval of a resolution approving a comprehensive plan amendment for Scannell Properties LLC to reguide roughly 75 acres located at 13001 County Road 10 from CO (commercial office) to MXD (mixed use). With all Commissioners voting in favor, the motion carried. (5.2) Approve conditional use permit amendment for outdoor storage of trucks and trailers for U-Haul at 1225 Highway 169 (2023043) Planning and Development Manager McGuire presented the staff report. Chair Boo asked how the limitation of ten came about. Planning and Development Manager McGuire stated that in reviewing the minutes it seemed the business only had ten trucks and that is why the condition was included in that manner. Chair Boo introduced the applicant, Christopher Bowman, who stated that he was available for questions. Commissioner Wixon commented that he lives near this property and noticed a buffer of grass about 25 to 30 feet in width. He asked if some trees could be placed in that area. Planning and Development Manager McGuire commented that there are some trees, but additional trees could be requested. Commissioner Wixon noted an area that does not have trees and believed trees would be a good addition in that location. 10 7 Proposed Minutes September 6, 2023 Commissioner Fowler asked if anything would be changing operationally. Mr. Bowman replied that as the business grew, this has been a successful location, and they would like to bring the site into compliance. Chair Boo opened the public hearing. No comments. Chair Boo closed the public hearing. Commissioner Wixon commented that he has noticed the growth of the business and congratulated the business as the site was previously vacant. Commissioner Anderson agreed with the suggestion for additional trees. Motion was made by Commissioner Wixon and seconded by Commissioner Anderson to recommend approval of the resolution as presented with additional screening, providing discretion for the developer to work with city staff on that item. With all Commissioners voting in favor, the motion carried. Adjournment Chair Boo adjourned the meeting at 8:19 p.m. 11 Regular Planning Commission September 20, 2023 Agenda Number:5.1 To:Planning Commission Prepared by:Chloe McGuire, Planning and Development Manager Reviewed by:Grant Fernelius, Community and Economic Development Director File No:2023042 1.

PROPOSAL: The applicant is requesting approval of the following: Site Plan Approval to allow for the construction of a three-story, 21- unit senior condominium building with underground parking and an outdoor pickleball court. Rezoning from FRD (Future Restricted Development) to O (Office) to accommodate the development of the senior condominium project. Variances for the following: 1. Wetland structure setback, for a portion of the building (southeast corner), of 4 feet 4 inches into to the required 15-foot setback. 2. A portion of a play and recreation facility (pickleball court) to be located in a front yard. Conditional Use Permit to allow for a maximum building height of 45 feet in the Office zoning district.

Notice of the public hearing was published in the City’s official newspaper and mailed to all property owners within 500 feet of the site. A copy of the notification area map is attached. Development signage is posted on the property. CONTEXT: Surrounding Land Uses Land Use Guiding Zoning Project Site Single Family Residential CO FRD North Single Family Residential in the Plum Tree 4th Subdivision LA-2 RSF-2 East Vacant C C-3 South Commercial (Culvers) C C-3 West Office Condominiums CO O Natural Characteristics of Site The site is located in the Bassett Creek drainage district. A medium quality wetland is located south and along the eastern portion of the property. The site is not located in a shoreland overlay district. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The city’s discretion in approving or denying a site plan is limited to whether the proposal complies with the comprehensive plan and zoning ordinance standards. If it meets the standards, the city must approve the site plan. The City has a relatively high level of discretion in approving or denying a rezoning application. This is because the rezoning of land is also a “quasi-legislative” action (enactment of policy). The zoning ordinance and map are the enforcement tools used to implement the goals and standards set by the comprehensive plan. The proposed zoning for a property must be consistent with the comprehensive plan. The city’s discretion in approving or denying a variance is limited to whether the proposal meets the standards for a variance. The city has a relatively high level of discretion with a variance because the burden of proof is on the applicant to show that they meet the standards for a variance. 15 2023042 Page 3 The City’s discretion in approving or denying a conditional use permit is limited to whether or not the proposal meets the standards listed in the zoning ordinance. If it meets the specified standards, the City must approve the conditional use permit. However, the level of discretion is affected by the fact that some of the standards may be open to interpretation. ANALYSIS OF REQUEST: The applicant is proposing to construct a three-story, 21-unit senior condominium building with an underground parking level on two lots (which will be required to be combined) at 18035 Old Rockford Road. The existing site is currently occupied by a one-story single family home with a garage and two small accessory buildings that will all be removed as part of this project. Site Plan The zoning ordinance contains specific standards for approval of a site plan in the O (Office) zoning district. Staff used these standards to review the proposed senior condominium development. Standards for the O (Office) District Specified Proposed Complies? Building Setbacks: --Front (from north lot line abutting Old Rockford Road) 25 ft. (min.) 70 ft. Yes --Side (from west lot line) 25 ft. (min.) 28 ft. Yes --Side (from east lot line) 25 ft.

Unknown --Fixture Height 30 ft. (max.) Unknown --Shielding Shielded fixtures within 300 ft. of residential Unknown --Correlated Color Temperature of Lighting 4100 Kelvin (max.) Unknown *Discussed below Density: The CO (commercial office) guiding lists types of development options as residential facilities such as nursing homes, assisted living facilities and senior citizen housing. Section 21450 of the zoning ordinance lists permitted uses within the office zoning district as elderly dwellings (senior citizen housing). The CO guiding designation specifies a minimum density goal of six dwelling units per acre and a maximum density of 20 dwelling units per acre. Density is based on net acreage excluding wetlands and related buffers, floodplain and land dedicated for arterial roadways. This method of calculating density is consistent with the procedures established by the Metropolitan Council. Based on the net acreage (1.08 acres), 7 to 21 dwelling units could be accommodated in accordance with the density guidelines identified in the comprehensive plan. Therefore, the proposed 21 units would be within the density guidelines. Access: Access to the building would come from Old Rockford Road, where two accesses are proposed. Parking: The ordinance requires 1.8 parking spaces per unit (at least one covered) for apartment dwellings. Using this formula, 38 parking spaces would be required. The proposed plan includes 18 surface parking spaces and 33 underground parking spaces for a total of 51 spaces. The proposed number of spaces meets the zoning ordinance requirements for parking. Lighting: The preceding table indicates issues related to the lighting plan. The site is in Lighting Zone 2 where: 1) parking lot lighting levels are limited to 2.5 lumens per square foot of parking area; 2) mounting height of light fixtures cannot exceed 30 feet; 3) light fixtures mounted higher than 12 feet that are located within 300 feet of residential property must be equipped with house-side shielding; and 4) the correlated color temperature (CCT) of lighting cannot exceed 4100 Kelvin. In addition, light fixtures must meet specified BUG (backlight/uplight/glare) ratings, and lighting levels must be reduced by at least 50 percent at 10 PM. The resolution requires that, prior to issuance of the building permit, the applicant submit a revised lighting plan for staff review and approval that complies with all lighting regulations. 17 2023042 Page 5 Building: The proposed project consists of a 3-story, 21-unit senior condominium building with underground parking. Proposed amenities include: • Fitness room • Level 1 common area with inset balcony/deck with patio and grill • Level 2 club room with an inset balcony • Outdoor pickleball court The units will range from large one bedroom unit with a den to large two bedroom units with a den. Each unit will have a large inset balcony. The exterior walls of the units and common areas are filled with extra tall windows for extra light and views to interior spaces. Proposed exterior materials used on the building include burnished block, fiber cement panels, wood-like siding on the balconies, and metal fascia. Section 21115.07 of the zoning ordinance also contains specific design requirements for apartments, including providing a minimum of two colors and two materials; offsets in the wall planes; and roof articulation. The proposal generally complies with these requirements but the Planning Commission could add a condition for additional rooftop articulation if the architecture does not appear to meet these requirements. Tree Preservation: Does not apply since there is no platting on this property. The properties must be consolidated at the County prior to work onsite. Landscaping: The zoning ordinance requires a minimum of two new overstory trees per dwelling unit for apartment developments with less than 50 dwelling units. In addition, a minimum of 15 percent of 18 2023042 Page 6 the required minimum number of trees for multi-residential developments shall be long-lived deciduous trees, 3.5 inches in diameter as measured six inches off the ground. The required number of overstory trees is 42. The submitted landscape plan meets the requirements of the zoning ordinance through the preservation of existing trees on site and providing new trees . The proposed sizes of the new trees also meet ordinance requirements. Wetlands/Floodplain: A large medium quality wetland is located south and east of the subject properties. A small portion of the delineated wetland is located in the southeast corner. The proposed development is subject to wetland buffer requirements consisting of a minimum of 24 feet and a maximum of 50 feet, for an average of 30 feet, from the delineated wetland. The applicant has submitted a wetland buffer and setback plan that meets zoning ordinance requirements with the exception of the variance request to the required 15-foot structure setback from the wetland buffer for a portion of the proposed building (southeast corner), as discussed below. A portion of the property contains Bassett Creek floodplain. The applicant has submitted a floodplain mitigation exhibit showing proposed cubic feet of floodplain greater than existing cubic feet of floodplain. A condition is included in the resolution related to meeting minimum floor requirements prior to the issuance of a building permit. Rezoning The site is currently zoned FRD, Future Restricted Development District. The purpose of this district is to provide a holding zone until a land owner/developer makes an application for development, at which time the City may rezone the affected property consistent with its designation in the Comprehensive Plan. A developer has come forward with the proposal for the senior condominium community, and the requested zoning at this time is O (Office) which allows for dwellings for senior citizens as a permitted use. The property has a land use designation of CO, Commercial Office, which does allow for a mix of uses if the development is carefully evaluated. A land use amendment is not required for this development. Variances The applicant has applied for the approval of two variances. One variance is a 4.4 foot variance to the 15-foot wetland structure setback (from buffer strip) on the south side of the site. The other variance is to allow for a portion of the outdoor pickleball court in the front yard of the site. Variance for Wetland Structure Setback Section 21670.05 references the required wetland setbacks for all types of development. The section establishes a 15-foot setback from the wetland buffer strip for all structures. As shown on the attached variance exhibit, the structure is encroaches into the wetland buffer strip setback by 4 feet 4 inches, which means that the building is only 10.6 feet from the wetland buffer strip. 19 2023042 Page 7 The applicant establishes proposed practical difficulties with complying with this section of the ordinance in the attached variance narrative. The narrative explains that the wetland boundary gets closer to the south lot line in the southeast corner of the site, and that the lot size is being decreased because additional right-of-way is being requested along Old Rockford Road. Variance for the Location of the Outdoor Pickleball Court A pickleball court is considered a play and recreational facility, as defined below, and these courts are not permitted within front yards. Therefore, a variance is required for the location of the courts within the front yard of the site. 21115.04. Subd. 1 of the zoning ordinance addresses play and recreational facilities and their allowed locations: The following shall not be considered as encroachments on yard setback requirements. (d) Pursuant to Section 21120 of this Chapter, accessory buildings and structures including, but not limited to, sheds, play and recreational facilities, private dog kennels, laundry drying equipment, and gazebos shall not be located in a front yard. Such accessory buildings or structures may be located within: 1) a side or rear yard, provided they comply with the minimum side or rear yard setback requirement for accessory structures as prescribed by the applicable district; and 2) a front yard which qualifies as an equivalent rear or side yard (as defined by this Chapter) provided they are set back from such front lot line a distanc e equal to, or greater than, the minimum front setback specified for the principal building on the lot, and comply with the minimum side yard setback requirement for accessory structures, as prescribed by the applicable district. No encroachment shall be permitted in existing or required drainage and utility easements, unless approved by the City Engineer. The exception is that eave overhangs and any related gutters for detached accessory buildings may encroach into a yard setback and drainage and utility easement up to 24 inches beyond the exterior walls of the building. Play and Recreational Facilities: Accessory structures and/or uses that are customary and incidental to the principal use of the site, including but not limited to swing sets, play structures, sand boxes, fire pits, skateboard ramps, batting cages, tennis courts, sport courts, swimming pools and their related aprons, and the like, intended for the enjoyment and convenience of the residents of the principal use and their guests. The variance proposed for the pickleball court is for a portion of a play and recreational facility within the front yard (in front of the furthest wall projection of the principal structure toward Old Rockford Road). The applicant establishes proposed practical difficulties with complying with this section of the ordinance in the attached variance narrative. The narrative explains that the wetlands on site make it difficult to move the court to the south or east of the site, and there are few locations on site for the flood plain mitigation that is required. Finally, the city will be asking for an additional seven feet of right-of-way on the north side of the site for Old Rockford Road, decreasing the size of the lot. 20 2023042 Page 8 Conditional Use Permit Section 21450.07 Subd. 3 indicates a conditional use permit is required for buildings in excess of height limitations, and the height limitation for this site is 35 feet. The applicant is requesting approval of a conditional use permit to allow for the construction of a building that is 45 feet in height. In addition to the general conditional use permit standards (attached), section 21450.07 of the zoning ordinance includes two specific standards for the Planning Commission to consider when reviewing the request: • For each additional five feet in height above 35 feet, the front and side-yard setback requirements shall be increased by one foot. As indicated in the previous table, the applicant has proposed additional setbacks on the front (north) property line and both the east and west sides of the development that exceed this requirement. • The construction cannot limit solar access to abutting and/or neighboring properties. The applicant has submitted an exhibit that identifies the anticipated shadowing impact on the adjacent properties on one day in December, March and June during the solstice. The exhibit shows different times throughout the day and indicates that the shadows from the building will not impact the homes north of Old Rockford Road with the exception of an hour after sunrise on December 22. Some shadowing around sunset in June does occur to the north. Staff finds the impact of the increased height acceptable. Staff used the attached conditional use permit standards to review the request and finds it would meet all of the applicable standards. Specifically, the proposed use: 1) Would be consistent with the comprehensive plan; 2) Would not endanger the public health or safety; 3) Would not be injurious to other properties in the vicinity or to the city as a whole; and 4) Would not impede the orderly development of surrounding properties. RECOMMENDATION: Community and Economic Development Department staff recommends approval of the site plan, rezoning, variances and conditional use permit that are associated with the development proposal to build 21 senior condominiums with underground parking and pickle ball court at 18035 Old Rockford Road. If new information is brought forward at the public hearing, staff may alter or reconsider its recommendation. 21 w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w w

The site is currently zoned as FRD, Future Restricted Development and contains wetlands. The site is currently occupied by a one-story home with a garage and small accessory building that will all be removed as part of this project. The proposed project consists of a 3 story, 21 unit senior condominium building with an underground parking level. The new proposed zoning for the site is Office District. The underground parking garage will provide 33 vehicle parking spaces, 10 of which are tandem stalls. There will be 18 additional stalls in a surface parking lot between the building and Old Rockford Road. Proposed interior amenities include a fitness room, Level 1 common area with inset balcony and a Level 2 clubroom that also walks out to an inset balcony. Exterior amenities include a large exterior deck off of the Level 1 common area that steps down to a patio with grill and is adjacent to an outdoor pickleball court. The size of the units will range from large one bedrooms with a den to large two bedrooms with a den. Each unit has a large inset balcony. The exterior walls of the units and common areas are filled with extra tall windows that provide plentiful light and views to the interior spaces and enhance the exterior appearance of the building. Proposed exterior materials include a sand colored burnished block that wraps the entire base of the building and meets the grade with a warm earthy tone. Above the masonry base, the majority of the exterior will be clad with high quality fiber cement panels with exposed fasteners. There will be two types of panels, a dark gray smooth panel and a lighter gray grooved panel that will provide variation on each façade. The grooved panels will create a dynamic look that changes gradually throughout the day based on variation in natural light. The darker smooth panels align vertically with the stacked windows to help break up the longer building elevations. The inset balconies and entry will add additional warmth to the exterior with a light wood-look siding in a light cedar finish. The top parapet and balcony fascias will be clad in dark gray or black metal to create distinct horizontal lines that define the shape of the building. As part of this project we will be applying for the following applications: - Site Plan Review for a 3 story, 21 unit senior condominium building. - Rezoning from FRD, Future Restricted Development to O, Office. - A variance to reduce the wetland structure setback at the South Elevation as shown on the proposed plan. - A variance to allow a portion of the proposed recreational facility in the front yard. - A Conditional Use Permit for maximum height to be raised from 35 feet to 45 feet. 38 PZ2023042 CONDITIONAL USE PERMIT DESCRIPTION FOR 18035 OLD ROCKFORD ROAD The proposed Conditional Use Permit is to increase the height of a building in an Office District from 35 feet to 45 feet. The proposed Conditional Use Permit is in compliance with the Plymouth Comprehensive Plan. The increase to height allows for residential development that makes efficient use of land and utilizes existing public infrastructure and incorporates sustainable design practices. The city’s 2040 comprehensive plan identifies land use for the site as Commercial Office which allows senior housing. The senior housing project will address the city’s aging population and need for more senior housing that is noted in the comp plan. The conditional use and resulting project will enhance housing quality and diversity in the city while also protecting the natural environment. The height of the lowest floor has been designed to be at least two feet above the existing water table. In addition, the heights of floor levels have been determined by incorporating Mass Timber construction which is an innovative and sustainable building practice. Mass Timber has less embodied carbon compared to other building materials, which indicates fewer greenhouse gas emissions. The wood used in Mass Timber construction is natural and renewable. The establishment, maintenance or operation of this conditional use will promote and enhance the general public welfare and will not be detrimental to or endanger the public health, safety, morals or comfort. The establishment of additional owner occupied senior housing will enhance housing options for Plymouth’s aging population. The Mass Timber building will be unique to the area and its aesthetic and sustainability will further enhance the general public welfare. The setbacks of the building have been increased based on the increased height. The height of the building will not limit solar access to abutting and/or neighboring properties as shown on the shadow study plan. The conditional use will not be injurious to the use and enjoyment of other property in the immediate vicinity for the purposes already permitted, nor substantially diminish and impair property values within the neighborhood. As mentioned in the above paragraph, setbacks have been increased and the increased height will not limit solar access to other property in the immediate vicinity. The setback on the west side of the property was increased at least one foot for every five feet added to the building height. The setbacks in the front and east side yards already exceed this amount. The establishment of the conditional use will not impede the normal and orderly development and improvement of surrounding property for uses permitted in the district. The height of the building will not impede development of surrounding properties. 39 PZ2023042 2 Adequate measures have been, or will be, taken to provide ingress, egress, and parking so designed as to minimize traffic congestion in public streets. There is adequate ingress, egress and parking to minimize traffic congestion. A one way exit was added to help with congestion and aid in maneuvering emergency vehicles. The conditional use shall, in all other respects, conform to the applicable regulations of the Office district. The conditional use complies with the general and specific performance standards as specified by Section 21015 and the Plymouth Zoning Ordinance. Exterior lighting on the building will not cast glare toward the public right of way or neighboring residential uses or districts. The architectural appearance and functional design of the building and site has been designed to have a neutral palette that complements its natural surroundings and reflects the Mass Timber construction of the building with wood look accents. All sides of the building have the same harmonious exterior finish materials and treatment. 40 PZ2023042 REZONING DESCRIPTION FOR 18035 OLD ROCKFORD ROAD The proposed Rezoning is from FRD, Future Restricted Development District to O, Office District. The purpose of the Future Restricted Development District is to provide a holding zone until a landowner/developer makes an application for development, at which time the City may rezone the affected property consistent with its designation in the Comprehensive Plan. The 2040 Comprehensive Plan designates the Land Use for the two lots that are part of this development as CO, Commercial Office. The current zoning district that is most similar to Commercial Office is the O, Office District. The proposed action meets the purpose and intent of the ordinance for a rezoning amendment. Adequate infrastructure, including roads and utilities are available to serve the proposed action. The rezoning is compatible with adjacent districts. The proposed O, Office District allows senior housing. The proposed senior housing project on these two lots will address the city’s aging population and need for more senior housing that is noted in the 2040 Comprehensive Plan. 41 PZ2023042 VARIANCE DESCRIPTIONS FOR 18035 OLD ROCKFORD ROAD The first proposed variance is to reduce the wetland structure setback at the South Elevation as shown on the proposed plan. The variance and its resulting construction or project will be in harmony with the general purposes of the zoning code and will be consistent with the city’s comprehensive plan. The reduced setback supports residential development that makes efficient use of land and utilizes existing public infrastructure and minimizes the development impact on wetland areas to the south and east. The city’s 2040 comprehensive plan identifies land use for the site as Commercial Office which allows senior housing. The senior housing project will address the city’s aging population and need for more senior housing that is noted in the comp plan. The variance and resulting project will enhance housing quality and diversity in the city while also protecting the natural environment. There are practical difficulties in complying with the 15 foot structure setback beyond the minimum 24 foot wetland buffer at one point along the South Elevation. The Medium Quality (Manage 2) wetland boundary is located to the south and east of the lots to be developed. The first practical difficulty is that the wetland boundary gets closer to the south lot line in the southeast corner of the site. The other practical difficulty is that the lot size along Old Rockford Road is being decreased by 7 feet for right of way. The City is requesting that 7 feet of the lot be given to the Old Rockford Road right of way in order to align with the property lines on the adjacent lots. The proposed reduction of the wetland buffer/structure setback is less than 7 feet. The variance request is not based exclusively upon economic considerations. The development of the site for senior housing is dependent on providing parking and building setbacks, sufficient parking area design, fire lane and sufficient building width. The proposed building width allows for efficient entry to the underground parking garage, provides space for three rows of parking (including one row for tandem spaces) and provides sufficient space for unit layouts on Levels 1-3 including larger two bedroom units that will be desirable for senior housing. The building size and placement from east to west allows an extra large buffer from the east boundary of the wetlands. The exterior amenities for the building, including an exterior deck, patio and pickleball court have been located on the east side of the building to minimize impact on wetlands while also providing sufficient area for drainage and stormwater mitigation. The variance, and its resulting construction or project, will not be detrimental to the public welfare, nor will it be injurious to other land or improvements in the neighborhood. There is only one narrow area where the building will go beyond the structure setback at the minimum 24 foot wetland buffer. At most other locations, the wetland buffer will be much wider 42 PZ2023042 2 than 24 feet so that on average the wetland buffer greatly exceeds the minimum amount. At the southeast corner of the building, the building extends into the structure setback for a stretch of about 55.8 feet and extends from 0 to 4.4 feet into the setback in this area. The total area of the variance requested is 210 square feet. This makes up about 30% of the South Elevation which is 183.2 feet long. The other 70% exceeds the minimum wetland buffer. The variance, and its resulting construction or project, will not impair an adequate supply of light and air to adjacent properties, nor would it substantially increase traffic congestion in public streets, increase the danger of fire, endanger public safety, or substantially diminish property values within the neighborhood. The proposed variance to reduce the structure setback at the wetlands does not affect supply of light and air to adjacent properties, traffic congestion, danger of fire, public safety or property values. The only impact is to the wetland buffer, which will be more than the minimum amount at all other locations. The variance requested is the minimum action required to address or alleviate the practical difficulties. The variance for reduced structure setback will allow for minimum impact on the wetlands to the south and east. The amount the building goes into the setback is due to the variation of the wetland boundary and the increased right of way. The width of the exterior drive aisle was reduced from 26 feet to 24 feet to minimize the variance request. The proposed site layout minimizes variances while also minimizing the impact on natural areas. The second proposed variance is to allow a portion of the proposed recreational facility in the front yard. The variance and its resulting construction or project will be in harmony with the general purposes of the zoning code and will be consistent with the city’s comprehensive plan. The proposed recreational facility, a pickleball court, is an amenity for a residential development that makes efficient use of land and utilizes existing public infrastructure, minimizing development impact on wetland areas to the south and east. The city’s 2040 comprehensive plan identifies land use for the site as Commercial Office which allows senior housing. The senior housing project will address the city’s aging population and need for more senior housing that is noted in the comp plan. The proposed pickleball court is an amenity that encourages health, fitness and wellbeing through community activity. The variance and resulting project will enhance housing quality and diversity in the city while also protecting the natural environment. There are practical difficulties in locating the recreational facility completely in a side or rear yard instead of locating a portion in the front yard. The front yard for the O District is 50 feet for a dwelling abutting an arterial street. The proposed pickleball court will extend approximately 18’-3” into the front yard and be located approximately 31’-9” from the front property line. The first practical difficulty is that there are protected wetlands to the south and east of the lots to be developed. The wetland buffers and setbacks extend into the lot to be developed. The second practical difficulty is that there are few locations on the site for floodplain mitigation. A rate control basin has been proposed for the east side of the site for floodplain mitigation. Finally, there is a practical difficulty that the lot size along Old Rockford Road is being decreased by 7 feet for right of way. The City is requesting that 7 feet of the lot be given to the Old Rockford Road right of way in order to align with the property lines on the adjacent lots. In combination, the reduced lot size and environmental 43 PZ2023042 3 site restrictions allow very little area outside of the building footprint for amenity spaces that support the health and fitness of the senior condo residents. The variance request is not based exclusively upon economic considerations. The development of the site for senior housing is dependent on providing sufficient parking and building area design within the given setbacks and environmental site restrictions. The building size and placement from east to west allows an extra large buffer from the east boundary of the wetlands and sufficient space for floodplain mitigation. The exterior amenities for the building, including an exterior deck, patio and pickleball court have been located on the east side of the building to minimize impact on wetlands. The variance, and its resulting construction or project, will not be detrimental to the public welfare, nor will it be injurious to other land or improvements in the neighborhood. The pickleball court is over 30 feet from the front property line and from 56 to 58 feet from the existing arterial street. The proposed court is setback over 20 feet further from the front property line than the parking area. Lighting and activity on the court will comply with city curfew restrictions for recreational facilities. The variance, and its resulting construction or project, will not impair an adequate supply of light and air to adjacent properties, nor would it substantially increase traffic congestion in public streets, increase the danger of fire, endanger public safety, or substantially diminish property values within the neighborhood. The proposed variance to allow a portion of the pickleball court in the front yard does not affect supply of light and air to adjacent properties, traffic congestion, danger of fire, public safety or property values. The court is at grade level and will be surrounded by a fence that complies with the zoning code. The court will only be used by senior condo residents and guests and will not create more traffic than what is already expected for this development. The variance requested is the minimum action required to address or alleviate the practical difficulties. The variance for allowing a portion of the pickleball court in the front yard will allow for minimum impact on the wetlands to the south and east. The proposed site layout minimizes variances while also minimizing the impact on natural areas. The size of the court and space around the court has been minimized while also maintaining safety standards for its intended use. 44 73 80 80 DRAINAGE AND UTILITY EASEMENT PER PLAT OF PLYMOUTH OFFICE PLAZA D R A I N A G E A N D U T I L I T Y E A S E M E N T P E R P L A T O F P L Y M O U T H O F F I C E P L A Z A 10 10 10 ' U T I L I T Y E A S E M E N T P E R PL A T O F P E O N Y P R O M E N A D E DRAINAGE EASEMENT OVER ALL OF OUTLOT A PER PLAT OF PEONY PROMENADE PROPOSED BUILDING GARAGE ELEV = 1011.2 HY D T GENERAL NOTES 1.

The site is not located in a shoreland overlay district. Previous Actions In 1985, the City Council approved the conditional use permit and site plan to permit construction of this Burger King Restaurant. In 1993, the Council approved an outdoor play area at the front of the building. In 1996, the City Council approved a conditional use permit amendment and site plan amendment to allow the construction of a playroom addition. In 2005, an administrative site plan amendment approval to allow exterior site lighting changes of the Burger King Restaurant. In 2019, Burger King vacated the building. Later in 2019, the city initiated code enforcement and eventually filed a property maintenance lawsuit against Burger King to maintain the property. The lawsuit was recently dismissed without prejudice with the expectation that Spire Credit Union will acquire the property. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City’s discretion in approving or denying a site plan is limited to whether or not the proposal complies with the comprehensive plan and zoning ordinance requirements. If it meets these standards, the City must approve the site plan. The City’s discretion in approving or denying a variance is limited to whether or not the proposal meets the standards for a variance. The City has a relatively high level of discretion with a variance because the burden of proof is on the applicant to show that they meet the standards for a variance. ANALYSIS OF REQUEST: The applicant is requesting approval of the following: a site plan and variances to construct a 5,050 square-foot Spire Credit Union with drive-through and associated site changes located at 10000 Rockford Road. 66 2023051 Page 3 Site Plan The zoning ordinance contains specific standards for approval of a site plan for development in the C-3 (highway commercial) zoning district. Staff used these standards to review the proposal. The specific standards that apply are as indicated on the following table. Standards for the C-3 District Specified Proposed Complies? Building Setbacks: --Front 50 ft. (min.) 80 ft.Yes --Sides 15 ft. (min.)42 ft.Yes Parking Setbacks: --From Lot Lines: South 20 ft. (min.)20 ft.Yes --From Lot Lines: West 20 ft.

(max.)28 ft.Yes Trash Receptacle Setbacks:50 ft.81’Yes Landscaping: 26 overstory trees (min.)40 Yes Parking Based on the proposed 5,050-square foot bank use, the site is required to have 21 parking spaces – one stall for each 250 square feet of floor area for the first 100,000 square feet, plus one space for each 350 square feet of floor area thereafter. The applicant has provided a site plan showing a total of 34 parking spaces to meet the zoning ordinance requirement. Lighting The project is located in lighting zone 2 (LZ2) and must meet the requirements under section 21105.06 of the zoning ordinance. The applicant submitted a lighting plan showing the proposed location, and fixture details. The applicant will need to provide lighting fixture details that meet the city’s B.U.G rating and a calculation of lumens per square foot of parking lot or other hardscape area to be lighted that meet the requirements of the LZ2. A condition to this effect is included in the attached resolution. 67 2023051 Page 4 Building Materials The primary building materials would include brick, EIFS, stone veneer, prefinished metal, and glass. The proposal would comply with City regulations relating to building materials and design. Landscaping Section 21130 of the zoning ordinance states that for new non-residential developments, a minimum of the greater of one new overstory tree per lineal feet of site perimeter (26 trees) or one new overstory tree per 1,000 square feet of gross floor area (six trees). Therefore, 26 overstory trees or equivalent overstory trees are required for this site. Up to 50 percent of the required number of overstory trees on a site may be substituted with an equivalent number of understory trees or shrubs. In such case, three understory trees or ten shrubs shall be equivalent to one overstory tree. The applicant has submitted a plan showing 11 new overstory and 29 existing trees to remain. The site will also contain a number of shrubs, perennials and grasses on site. The proposed number of overstory trees meets the minimum requirement. Access/Traffic Circulation The main entrances and exits for this site would be located in approximately the same location as exist currently. The applicant is proposing a one-way entrance on the east side that will direct employees to the rear parking lot and customers to the drive-throughs. The proposed drive-through will have four lanes with the outer lane as a future ATM lane. The applicant is requesting a variance to not provide a by-pass lane for the drive-through. 68 2023051 Page 5 Drive-through standards Section 21120.04 of the zoning ordinance includes the following performance standards for drive- through windows: The operation shall be responsible for litter control within 300 feet of the premises and litter control is to occur on a daily basis. Trash receptacles must be provided at a convenient location on site to facilitate litter control. A condition to this effect is included in the attached resolution. The drive-through is required to be located on properties with direct access to minor arterial, collector or service road. The site currently located on a service roadway. All elements of the drive-through service window must be at least 300 feet from residential properties. All elements of the drive-through is 300 feet away from residential properties. The facility’s public address system shall not be audible from any adjacent residentially zoned or guided property and shall comply with Section 21105.10 of this Chapter. A condition to this effect is included in the attached resolution. The drive-through must be designed for a minimum stacking of 4 cars per lane. The applicant shows 4 vehicles stacked on the plans. The use cannot significantly lower the existing level of service on streets and intersections. Staff finds that the impact on the existing service level would be acceptable. No alcoholic beverages may be sold or served in the drive-through lane. The applicant indicated that the restaurant does not serve alcoholic beverages. Staff included a condition to this effect in the attached resolution. All elements of the drive through service area, including but not limited to associated signage, order stations, teller windows, and vehicle lights from the stacking lanes, shall be screened from adjacent residentially zoned or guided property pursuant to Section 21130.03 of this Chapter. The applicant has indicated all elements will be screened. Sites with drive-through service shall be designed in a manner that allows drivers not using the drive-through, or wishing to exit the drive-through area, to bypass the drive-through lane(s). The applicant is asking for a variance for this item but applicant notes that the project is providing a 20-foot one-way drive in this area that would allow drivers to bypass those waiting for the drive-through. Staff used the attached conditional use permit standards to review the request and finds it would meet all of the applicable standards (variance for bypass lane discussed below). Specifically, the proposed use: 1) would be consistent with the comprehensive plan; 2) would not endanger the public health or safety; 3) would not be injurious to other properties in the vicinity or to the City as a whole; and 4) would not impede the orderly development of surrounding properties. Variances The applicant is requesting the following variances: 1. Not providing a bypass lane for the drive-through. 2. Additional wall signage Bypass lane variance Section 21120.04 of the zoning ordinance requires drive-throughs to have a bypass lane to allow motorists to exit if needed. The applicant is requesting to not provide a bypass lane for the drive- 69 2023051 Page 6 through because of the unique shape of the lot and by adding the bypass lane would result in significant loss of parking and building setback issues. The drive-through lanes are positioned at the rear of the building and will provide for stacking for a minimum of four cars each and on a typical day will have room to maneuver through the site. Wall Signage Variance Section 21155.06 Subd. 4(b)(1)(b) of the zoning ordinance requires only allows signage on one wall when the site fronts one street and the proposed signage shows signage on two walls. The applicant is requesting to place signage on two walls in an effort to help customers approaching from the frontage road. One wall sign is proposed on the south side of the building facing Rockford Road and the other would be on the west elevation, facing towards Nathan Lane. Findings In review of the request, staff finds that all of the applicable variance standards would be met, as follows: 1) The requested variances, and resulting construction, would be in harmony with the general purposes and intent of the ordinance, and would be consistent with the city’s comprehensive plan. 2) The applicant has demonstrated that there are practical difficulties in complying with the ordinance regulations, because: a. The applicant proposes to use the property in a reasonable manner. The commercial uses would be consistent with the existing surrounding development. b. The request is due to circumstances unique to the property that were not created by the landowner. The existing property is a unique shape and the requested variances would help create safe and efficient traffic flow patterns throughout the site and eliminate potential congestion on the frontage road. c. The variances would not alter the essential character of the neighborhood the traffic circulation is still available around the building and the additional signage would help in wayfinding and is not an increase in signage area but breaking up the maximum signage allowed and providing it on two walls. 3) The requested variance is not based solely upon economic considerations. The applicant is requesting the variances in order to configure the site to create a safe and efficient traffic flow throughout the site and to provide additional visibility and wayfinding to the site. 4) The variances, and resulting construction, would not be detrimental to the public welfare, nor would it be injurious to other land or improvements in the neighborhood. 5) The variances, and resulting construction, would not impair an adequate supply of light and air to adjacent properties, nor would it increase traffic congestion or the danger of fire, endanger the public safety, or substantially diminish property values within the neighborhood. 70 2023051 Page 7 6) The variances requested are the minimum action required to address the practical difficulties. The Planning Commission must review the variance request for compliance with the standards outlined in the zoning ordinance.

The proposed project would demolish, in its entirety, the existing outdated and non-conforming Burger King structure and site. After demolition, Spire Credit Union’s goal is to construct a modern branch office that offers adequate parking for members and staff as well as drive-up facilities that have become essential in modern banking. The proposed project would represent a large investment in the City of Plymouth as well as provide a benefit to the local community. The proposed new branch would be a major improvement to the site in many ways, but a few key areas that will have an immediate effect on the surrounding area: The project will not only replace an unoccupied and outdated building but will provide a modern building that is in line with the City’s vision for materials and design set forth in the City’s Architectural and Materials Standards. The proposed building will be designed using Spire Credit Union’s latest prototype design. It is an exciting and visually appealing building that will fit well into the local community. It utilizes premium exterior and interior finishes, varied roof heights and intriguing façade design. Renderings and elevations have been included with the package to help illustrate the proposed building design. The project is environmentally friendly: there will not only be a reduction in impervious surface, but also an increase in green space and landscaping. The site design will also incorporate all the latest advances in stormwater management and minimal design impact standards (MIDS). The new building will be built not only to comply but exceed current energy codes and will utilize environmentally friendly materials and construction methods where possible. The redesigned site has been developed in coordination with both the planning and engineering departments at the City. The credit union branches will generate traffic during business hours. All traffic will be managed onsite with excellent stacking capabilities for the dive-through within the new site design. While not finalized, Spire’s typical hours of operation are Monday – Thursday 9a-5p; Friday 9a- 6p; Saturday 9a-12p. Employee counts have not been finalized, but typical employment would be between 9-11 employees depending on time of day and staffing needs. As part of their commitment to the community, Spire attempts to hire local employees from the area. This project will not have any effect on the following items: o There will be no change to population and density upon surrounding land uses resulting from the project. o There will be no increase in noise, odors, smoke, gas, vibration, or increase in pests resulting from the project. o There will not be a reduction in public safety, health or welfare resulting from the project. 78 DATE: August 25, 2023 Variance Standards 79 P a g e 2 • • • 80 P a g e 3 81 Chris Clark Spire Credit Union Plymouth, MN 07-24-202 Scale: 1/8”=1’-0” SFCU_PLY_CL_V1A.ai illuminated channel let- ters Customer Location Description Sales Person Date Scale File / Rev This is a proprietary design of Leroy Signs, Inc., designed specifically for this project.

Ft. TOTAL EXISTING HARDCOVER 2,810 Sq. Ft. AREA OF LOT 7,971 Sq. Ft. PERCENTAGE OF HARDCOVER TO LOT 35.3% 99 Maxar, Microsoft 100 Brief description of Variance Request: We are applying for a variance request at our property address of 9600 17th Ave North to allow for a backyard shed to be installed and increase impervious surface from proposal 35.3% to now 39.4%. Building a new house at our current property is our family's dream since we have purchased the property over 10 years ago. It had a hardcover 48% before starting new building process. We believe our request for a variance is reasonable for a few reasons. 1) This is a very small size of lot. Only 0.18 ac. It has grandfather hardcover 48%. Now hardcover is 39.4% and dramatically decrease hardcover surface. House has been built with ICF blocks which it has 12” thickness exterior walls taken more interior space than tradition one. ICF is Eco friendly Geen block. The backyard shed will be good use and keep the backyard clean and neat. 2) Best Management Practice (BMP) Solutions available: We would be happy to work closely with the city planning team to ensure the final design incorporates the necessary BMP to ensure limited rainwater runoff from our property. We have installed a 250-gallon rain barrel in the Northeast corner. Please see attached photos. We will be more than happy to make some changes if city planning team has some recommendations and suggestions. In summary, we are requesting a variance from the City of Plymouth to allow backyard shed to be installed and increase impervious surface to 39.4% from proposal 35.3 at 8600 17th Ave North. We can work with the planning team so that it does not have negative consequences from a water runoff standpoint. We very appreciate your consideration. Tom and Lan. 9600 17th Ave North. 101 Community and Economic Development Department 3400 Plymouth Blvd Plymouth, MN 55447 (763) 509-5450 What is the proposed project? Explain what you’re doing and why you need a variance. It is a new build process for 9600 17th Ave North, Plymouth, MN 55441. From final AS_BUILT survey, impervious (Hardcover) is 39.4%. And proposed is 35.3%; It increases 4.1%; Driveway increases about 2.5%. Patio and rain harvest system base add about 1.2%. The shed adds about 0.08%; Other miscellaneous adds about 0.32%. It had 48% impervious surface before the new building process starts. With rise issue with impervious surface coverage over proposed during the phase of building shed, Homeowner (BUILDER) would like to have a city approval variance which over the proposed impervious surface percentage. Would the variance, and its resulting construction or project, be in harmony with the general purposes and intent of the Zoning Ordinance, and consistent with the comprehensive plan? Explain. The shed has been designed to match the current new house design. Please see attached 3D designs. Driveway hardcover increases to match the garage width, which is good to fit the property. Would the variance, and its resulting construction or project, be detrimental to the public welfare, or injurious to other land or improvements in the neighborhood? Explain. The shed has setback back in place. Originally it has two car garage without setback. The shed is perfect to fit and good use with new property. It has a similar shed around the neighborhood. Driveway hardcover is naturally to fit with new house and the same as miscellaneous hardcover. Would the variance, and resulting project, impair an adequate supply of light and air to adjacent properties, substantially increase traffic congestion in public streets, increase the danger of fire, endanger the public safety, or substantially diminish property values within the neighborhood? Explain. According to the survey, the shed will not result project, impair an adequate supply of light and air to adjacent properties. The shed is used by homeowners for storage garden tools and will not substantially diminish property values within the neighborhood. Increased driveway hardcover will be naturally look and feel about property. 102 Community and Economic Development Department 3400 Plymouth Blvd Plymouth, MN 55447 (763) 509-5450 Explain the “practical difficulties” present by answering the following questions: Is the variance the minimum action required to address or alleviate the practical difficulties? Explain. Do you plan to use the property in a reasonable manner, permitted by the Zoning Ordinance? Explain. Yes, we are live here as single-family house and planning for long term. Would the variance, if granted, alter the essential character of the locality? No. Is the variance request based exclusively upon economic considerations? Explain. No. It is to store some miscellaneous garden tool and such to make backyard looks good and neat. Is the difficulty due to circumstances unique to the property and was the issue created by the property owner? Explain. This is a very small size of lot. Only 0.18 ac. It has grandfather hardcover 48%. Now hardcover is 39.4% and dramatically decrease hardcover surface. House has been built with ICF blocks which it has 12” thickness exterior walls taken more space interior than tradition build. ICF is Eco friendly Geen block. 103 104 250-gallon rainwater collection system 105 Agenda Number File 2023056 PLYMOUTH COMMUNITY DEVELOPMENT DEPARTMENT PLANNING AND ZONING STAFF REPORT TO: Plymouth Planning Commission FROM: Chloe McGuire, AICP, Planning and Development Manager MEETING DATE: September 20, 2023 APPLICANT: Tom Li PROPOSAL: Variance to impervious surface coverage for a shed in the rear yard at 9600 17th Ave LOCATION: 9600 17th Ave GUIDING: LA-1 (living area 1) ZONING: RSF-2 (single family detached 2) REVIEW DEADLINE: December 28, 2023 DESCRIPTION OF REQUEST: The applicants are requesting approval of a variance to keep a shed on the property which increased impervious surface from 35.3% to 39.4%, where the zoning ordinance allows a maximum of 25%. Notice of the public meeting was mailed to all property owners within 200 feet of the site. A copy of the notification area map is attached. Staff received correspondence from two neighbors about this project - a complaint about the shed and a call from a neighbor concerned about the shed staying onsite (recommended denial of variance). 106 Page 2 Surrounding Land Uses Adjacent Land Use Guiding Zoning North, East Single-family homes LA-1 RSF-2 South Industrial I I-3 East, Northeast Public P-I P-I Natural Characteristics of Site The lot is located in the Bassett Creek watershed and fully within the Medicine Lake Shoreland Management Overlay district. The property contains no wetlands and is not located in a floodplain overlay district. The site is approximately 275 feet from the edge of Medicine Lake (ordinary high water line). Properties within the shoreland overlay district, which are also limited in their impervious surface coverage, are shown in the map to the right within the colored circles around water bodies. Around 5400 residential parcels that are completely within the Shoreland layer (zoned one of the RSF, RMF or PUD). 107 Page 3 Previous Actions Affecting Site and Timeline of Actions Year Action 1999 Small house seen onsite in aerial photos 2002 Rear yard garage seen onsite in aerial photos Impervious surface rules implemented by city per State of Minnesota, limiting impervious surface coverage allowable levels 2013 New owners purchase property (current owners, applicant) 2015 Rear yard garage torn down NOTE: 180 days after tear-down, property loses nonconforming rights (grandfathered) to this impervious surface coverage 2018 Building permit approved – proposed to tear down house and build at lower impervious amount Survey noted a reduction in impervious from 48.3% to 35.3%, which is still over the allowable 25% threshold, but a reduction in overall impervious, so it could be administratively approved. 2019 Construction 2020 Construction 2021 Construction 2022 Construction 2023 Owner puts up shed, complaint received by city about shed and impervious surface. Through inspection and survey, found to be over allowed impervious surface. June 2023 – First Notice of Violation regarding Shed August 2023 – Second Notice of Violation regarding Shed August 2023 – Variance request submitted. Survey shows 39.4% impervious where only 35.3% is allowed Note: Construction of the home is not yet finalized. The need for additional storage onsite may be related to the construction of the home (which can be seen in photos) and staff finds that the new home is of a reasonable size that once completed, should meet the needs of reasonable storage onsite. Additionally, this is a new home. Staff finds that additional storage could have and should have been considered during the design process, which was less than 5 years ago and the home has been in construction during all of these years. The home does not have a certificate of occupancy yet. The applicant also received note from the city in July 2023 that he was not in compliance with city tree planting rules, which require 2 new trees in the front yard of new homes. These trees were not planted. 108 Page 4 LEVEL OF CITY DISCRETION IN DECISION-MAKING: The city’s discretion in approving or denying a variance is limited to whether or not the proposal meets the standards for a variance. The city has a relatively high level of discretion with a variance because the burden of proof is on the applicant to show that they meet the standards for a variance. The applicant’s response to the variance standards is attached. ANALYSIS OF REQUEST: The applicants request the variance to keep a shed in the rear yard of the property. The shed is under 200 square feet. Section 21665 of the zoning ordinance allows a maximum of 25% impervious surface coverage on all properties within 1,000 feet of a lake. The applicants’ survey indicates that their property would contain 39.4% impervious surface coverage and will remain at that amount if the variance is approved, though they are lawful, nonconforming at 35.3%. To approve a variance, the City Council must make the following findings, per Section 21030 of the Zoning Ordinance. The following findings are written for denial of the variance request. 1. Would the variance, and its resulting construction or project, be in harmony with the general purposes and intent of this Chapter, and be consistent with the comprehensive plan? Finding: Staff finds that the request is in harmony with the RSF-2 Zoning Ordinance, where single family homes are an allowed use, and sheds are an approved accessory use, and consistent with the LA-1 Guiding. 2. Is the variance request is based exclusively upon economic considerations? Finding: Staff finds that the request is not solely based on economic considerations, but may be partially based upon economic considerations resulting from the construction of the main home, which is not yet finalized. 3. Would the variance, and its resulting construction or project, be detrimental to the public welfare, or would it be injurious to other land or improvements in the neighborhood? Finding: Staff finds that the request may be detrimental to the public welfare, and would not be injurious to other land/improvements in the neighborhood. The applicant is requesting an increase in impervious surface, which can impact adjacent properties with increased runoff. A goal of the impervious surface regulations (intent below) are to protect water quality and lay out recommendations for the built environment around our lakes. The intent of the shoreland regulations: The regulations contained in this section are intended to guide and govern the wise development of shoreland of public waters, thus preserving and enhancing the quality of surface waters, preserving the economic and natural environmental values of shorelan ds, and providing for the wise utilization of water and related land resources in the City. It is the intent 109 Page 5 of this section to implement the goals and objectives of the Comprehensive Plan with respect to the identified shoreland areas. The regulations con tained within this section establishing this overlay district are intended to manage areas suitable for development of varying types as allowed in the underlying zoning district. It is the intent that this section be administered in conjunction with the ad opted land use regulations and requirements of this Chapter and of other ordinances, codes, and policies. The applicant proposed a rain barrel to offset the increase in impervious surface, which may help alleviate the increased runoff, but the property is already 10% over the allowable impervious surface and staff finds that the home can function reasonably at its current state. 4. Would variance, and its resulting construction or project, impair an adequate supply of light and air to adjacent properties? Or would it substantially increase traffic congestion in public streets, increase the danger of fire, endanger the public safety, or substantially diminish property values within the neighborhood? Finding: Staff finds that the request would not impair light and air, nor increase traffic, risk of fire, nor endanger the public safety, nor dimmish property values in the neighborhood. Staff finds that the variance request is consistent with uses in this zoning district. 5. Is the variance requested is the minimum action required to address or alleviate the practical difficulties? Finding: Staff finds that there are no practical difficulties onsite, and that the shed was built without a prior variance. Storage on this property could be within the single family home and attached garage. 6. Practical Difficulties Does the applicant propose to use the property in a reasonable manner permitted by this Chapter? Finding: Staff finds that the request is reasonable. Sheds are a permitted use in the RSF-3 District. Is the plight of the landowner is due to circumstances unique to the property that were not created by the landowner? Finding: Staff finds that the variance request is due to situations created by the landowner. The property owner recently applied to tear down and rebuild the home and property, in 2018, with 35.3% impervious surface, which is already more than 10% higher than allowed in this district. The The variance, if granted, would not alter the essential character of the locality? Finding: Staff finds that the request would alter the essential character of the locality, finding that increased impervious surface leads to impacts on adjacent properties. Additionally, staff has received feedback from neighbors that the shed is not in character with that of the locality. 110 Page 6 If the Planning Commission recommends approval of the variance, each of the above findings must be made by the Planning Commission for approval. RECOMMENDATION: Staff recommends denial of the requested variance subject to the conditions listed in the attached resolution. 111 CITY OF PLYMOUTH RESOLUTION NO. 2023- RESOLUTION DENYING A VARIANCE TO THE IMPERVIOUS SURFACE COVERAGE REQUIREMENTS AT 9600 17TH AVENUE NORTH (2023056) WHEREAS, Tom Li has requested approval of an impervious surface variance for an existing shed at 9600 17th Avenue North; and WHEREAS, the subject property is legally described as: Lot 12, Block 2, Inglebrae Addition, Hennepin County, Minnesota; and WHEREAS, the Planning Commission has reviewed said request at a duly called public meeting. NOW, THEREFORE, BE IT HEREBY RESOLVED BY THE CITY COUNCIL OF THE CITY OF PLYMOUTH, MINNESOTA, that it should and hereby does deny the request by Tom Li for an impervious surface coverage variance for a shed at 9600 17th Avenue North, subject to the following findings and conditions: 1. The requested variance to allow increased impervious surface coverage to allow an approximately 8.5 x 8.5 foot shed, increasing the impervious surface on the property from 35.3% to 39.4%, where 25% is allowed, is hereby denied, in accordance with the application received by the city on August 16, 2023 and with additional information on August 29, 2023, except as amended by this resolution. 2. The requested variance is denied, based on the finding that all applicable variance standards would not be met, as follows: a) The applicant has not established that there are practical difficulties in complying with the ordinance regulations, because: 1) The request is due to circumstances created by the landowners as they purchased the property in 2013, tore down the garage in 2015, and had an approved survey at 35.3% impervious in 2018. 2) The variance would alter the essential character of the lot or neighborhood given the number of homes around Medicine Lake within the shoreland overlay district that are subject to the 25% impervious surface coverage limit. This property is already over the allowed, and recommended 25% impervious surface coverage limit, at 35.3%. Additionally, the current home is still under construction and the property owner does not need a variance to provide for additional space to grow onsite. 112 Resolution 2023- (2023056) Page 2 3) There is nothing unique about this property in terms of layout, size, or physical characteristics that necessitate this variance. The building permit was recently approved for a new construction home on this property and the home has not yet received a certificate of occupancy. b) The requested variance and resulting construction would be injurious to other land or improvements in the neighborhood. The shed was built prior to a variance, and all adjacent properties are also within the shoreland overlay district, subject to 25% lot coverage. An increase in impervious surface can impact water quality, runoff to the lake and adjacent properties, and the aesthetics of the property. The property is already over the maximum allowed impervious surface based on previous lawful, non-conforming status. c) The city maintains a commitment to environmental protection and attempts to complies with the regulations set forth by the State of Minnesota regarding impervious surface coverage whenever possible. d) The variance request is not the minimum action required to address the items that the applicant has noted as practical difficulties. The city finds that there are no practical difficulties onsite, and that additional yard storage on the property can be put within the home that is still under construction on the subject property. 3. The shed must be removed from the property. Any increase in impervious surface will require a variance prior to construction or installation on this property. The property shall be reverted to what was approved by the building permit in 2018. APPROVED by the City Council on this _______ day of __________, 2023. STATE OF MINNESOTA) COUNTY OF HENNEPIN) SS.
