Request by Northern States Power (Xcel Energy) for approval of a PUD Final Site and Building Plan to construct an electrical substation. CD Technician Grant presented the final site and building plan from Xcel Energy to construct an electrical substation within the Project Bigfoot PUD. Commissioner Comments Chair Reed asked how the substation's fencing compares to any other substations that are located within Rosemount. Senior Planner Nemcek shared that there is another substation close to Flint Hills Resources, and the fencing of the proposed substation likely has more screening compared to the other substation. The Public Hearing opened 7:07 p.m. Kirstin Sersland, Xcel Energy Jake Andre, Xcel Energy Marcus Green, ERM Chair Reed asked about the electromagnetic field (EMF) radiation levels associated with the substation. Sersland clarified that the EMF levels were of greater concern to Project Bigfoot compared to the substation itself, noting that the Minnesota Pollution Control Agency (MPCA) regulates Xcel Energy to monitor EMF levels. Sersland noted the high-security fencing surrounding the substation is designed to enhance privacy and prevent unauthorized access by both animals and humans. Commissioner Beadner requested clarification on the presence of two substations within the Project Bigfoot Planned Unit Development (PUD) adjacent to the proposed substation, as well as whether the substation would serve the City of Rosemount. Sersland elaborated on the interconnection of the proposed substation with the other private substation, and how the connected transmission line links to other substations and feeders, ultimately providing power to Rosemount. Commissioner Whitman inquired about the potential integration of renewable energy sources associated with the substation. Sersland explained that while the incoming electricity is not renewable, further details regarding renewable energy pertain more to Project Bigfoot. Andre expanded on Xcel Energy's ongoing sustainability and renewable energy initiatives. Commissioner Buggi inquired about the timeline for transferring the Stormwater Pollution Prevention Plan (SWPPP) from Project Bigfoot to Xcel Energy, and the process involved. Green clarified that the SWPPP will transfer during the grading permit process, dependent on Xcel Energy's determination of Project Bigfoot's satisfactory completion of the SWPPP for the entire site.

Request by KJ Walk, Inc for Preliminary and Final Plat approval for Rosewood Commons 3rd Addition. Planner Hogan presented the request by KJ Walk to plat five buildable commercial lots and one outlot in anticipation of future commercial development within the Rosewood Commons Third Addition. Commissioner Comments Chair Reed asked the status of potential medium-density residential development plans located north of the memory-care facility. Planner Hogan stated that the City has not received any updated plans for development of that area. Senior Planner Nemcek deferred to the applicant to provide further details regarding the approved buildable lots within the Planned Unit Development (PUD). Chair Reed and Commissioner Ellis asked about traffic flow and planning for higher traffic as development progresses. Planner Hogan provided insights into how traffic-related concerns will be addressed collaboratively by both the City and the County. Nemcek added that moving forward, there are plans to reconfigure the intersection into a three-quarter intersection rather than a full intersection. The Public Hearing opened at 7:18 p.m. Luke Israelson, KJ Walk, Inc. - 14738 Lyndall Ln NE Prior Lake, MN Israelson shared that a building permit is being submitted for Lot 7 the following week, with plans to start building the first apartment building in summer, 2024.

Storm Sewer Trunk Charge: $6,865/acre BACKGROUND SUMMARY Owner Earl Street Partners II, LLC Preliminary Plat Acres 18.24 acres Met Council Net Acres 13.26 acres Page 9 of 112 Residential Lots Created 66 single family lots Gross Density 4.98 units per acre Comp Plan Guidance MUR - Mixed Use Residential Current Zoning PI PUD - Public/Institutional Planned Unit Development Proposed Zoning R1 PUD - Low Density Residential Planned Unit Development Surrounding Land Uses North: Mixed Use Residential East: Mixed Use Residential South: Agriculture Research West: Mixed Use Residential The Planning Commission is being asked to consider a request by Maplewood Development for approval of rezoning and preliminary and final plats for Amber Fields 18th Addition to create 66 single family lots. The lots created will be traditional single family lots with widths of 50’. The proposed 18th addition area was initially reserved for a future school site, but the developer has indicated to staff that the school district will not be acquiring the land for a school as the acreage needed is much higher than what is available on this site. Due to this change, the site will need to be rezoned from PI PUD – Public Institutional Planned Unit Development to R1 PUD – Low Density Residential Planned Unit Development to accommodate for the residential development. Based on staff’s calculations, the additional units will not cause the site to exceed the maximum density of the land guided for MUR. The proposed plat meets the lot standards for the R1-Low Density Residential zoning district and the Amber Fields Planned Unit Development. Staff is recommending approval of the rezoning and preliminary and final plats, subject to the conditions included in the recommended action and the Engineers Memo dated May 13, 2024. BACKGROUND The present applications are the latest step in a long process of planning for the development within UMore Park. The developer received Planned Unit Development approval with Rezoning from the City Council at its September 7, 2021, meeting. The Planned Unit Development anticipated roughly 1,959 residential units, which were to include a mixture of housing types such as single-family lots, townhome lots, and multi-family lots. There are a total of 17 Amber Fields additions that have been approved by the City Council. Preliminary Plat Areas that have been approved by City Council include Amber Fields 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 13th, 14th, 15th, and 17th additions with additions 9th, 10th, 11th, 12th, and 16th being the remaining areas of the designated preliminary plat areas that are shown in the table below. There has been a total of 1,919 housing units approved so far within the Amber Fields Development Area and the table below shows the breakdown of units that have been approved per addition. The previously approved Amber Fields 6th Addition will be going back in front of the Planning Commission for rezoning and major amendment to the Amber Fields Planned Unit Development Agreement approval to allow for 178 townhomes to be constructed on site instead of the previously approved 268 units. This would bring down the count of total approved housing units to Page 10 of 112 1,829 units if approved by the Planning Commission and City Council. Amber Field Additions Housing Type Total Units Approved by City Council Amber Fields 2nd, 12th, and 16th Additions Single Family and Townhome 301 units May 2022, September 2023, and March 2024 Amber Fields 3rd and 11th Additions Townhome 182 units June 2022 and September 2023 Amber Fields 4th and 9th Additions Single Family 108 units July 2022 and April 2023 Amber Fields 5th and 10th Additions Single Family 124 units July 2022 and April 2023 Amber Fields 6th Addition Multifamily 268 units July 2022 Amber Fields 7th Addition Multifamily 250 units August 2022 Amber Fields 8th Addition Multifamily 160 units December 2022 Amber Fields 13th Addition Single Family 65 Units October 2023 Amber Fields 14th Addition Townhome 174 units February 2024 Amber Fields 15th Addition Single Family 167 units February 2024 Amber Fields 17th Addition Single Family 120 units April 2024 The developer is proposing 66 single family lots throughout the 18.24-acre section of the Amber Fields development area. This addition is located in the southeastern portion of the development, directly east of Akron Ave and west of the Amber Fields 15th Addition preliminary plat area. The Amber Fields 18th Addition subdivision is planned to be built in one phase. ISSUE ANALYSIS Legal Authority Preliminary and Final Plat requests are quasi-judicial decisions for the Planning Commission, meaning that the Planning Commission is acting as a judge to determine if the regulations within the Comprehensive Plan, Zoning Ordinance and Subdivision Ordinance are being followed. If the proposed plats meet the ordinance requirements, they must be approved. Rezonings are a legislative decision for the city, but the rezoning must conform with the adopted Comprehensive Plan to be approved. Therefore, while technically legislative in nature, if a rezoning is in line with the Comprehensive Plan, it should be approved. Staff’s review of each application is provided below. General Subdivision Design The preliminary plat area is located in the southeastern portion of the Amber Fields Development, directly east of Akron Avenue and west of the approved Amber Fields 15th preliminary plat area. The site is also located south of open land owned by the City which will be turned into a park area with pickle ball courts and a dog park. The land south of the site is land owned by the University of Minnesota. The main access into the site will be from two streets that intersect Akron Avenue, shown as Adamstown Drive and Aster Blvd on the plans. Adamstown Drive will be the southern access road to Page 11 of 112 the area off Akron Avenue and will extend east to connect to the Amber Fields 15th Addition area. Aster Blvd will be the northern access for this area and will also extend east for connection to the 15th Addition. The plans also show a north-south road called Altomonte Way which will extend off of Adamstown Drive and Aster Blvd for connection within the 18th Addition. Additionally, there will be another road that extends east off Altomonte Way called Achilles Drive which will give connections to the rest of the preliminary plat area, as well as the 15th preliminary plat area. Because Akron Avenue is a County road, access onto it will be limited in the future when Akron Avenue is extended as County Road 73, and only right in and right out maneuvers will be allowed where Adamstown Drive intersects Akron Avenue. There is one outlot shown on the site, which will be located in the southernmost area of the plat that abuts up to University of Minnesota land. The applicant has provided a phasing plan that shows development to be built out in one phase. This includes the 66 single-family lots as well as Altomonte Way and Achilles Driveway, which interconnect the 18th Addition. Rezoning and Land Use The site is designated for MUR-Mixed Use Residential land uses, which can include a range of housing types from single-family homes on traditional sixty-five foot lots to townhomes. The zoning district in which the preliminary plat area is located in is the PI PUD – Public/Institutional Planned Unit Development district. This area was originally planned for a school site, but most recent conversations with the developer indicate that the district will not be acquiring the land for a school as the acreage needed is much higher than what is available at that site. The applicant is now asking for the site to be rezoned from PI PUD to R-1 PUD – Low Density Residential Planned Unit Development to allow for residential development to occur in this area. The Amber Fields Planned Unit Development Agreement includes several deviations from the Zoning Ordinance. In addition to dimensional standards, the table below compares the proposed preliminary plat to the standards of the Amber Fields PUD. Category Required (Amber Fields PUD) Amber Fields 18th Addition Min. Lot Area (sf) 5,400 sf (interior) 7,200 sf (corner) 6,425 sf (interior) 8,537 sf (corner) Min. Lot Width 45 ft. (interior) 55 ft. (corner) 50 ft. (interior) 60 ft. (corner) Min. Front Yard Setback 25 ft 25 ft. Min. Side Yard Setback 10 ft. dwelling/5 ft. garage/20 ft. corner 10 ft. dwelling/5 ft. garage/20 ft. corner Min. Rear Yard Setback 20 ft. 20 ft. The Amber Fields PUD also includes a deviation from the maximum lot coverage as follows: The maximum lot coverage shall be fifty-five percent (55%) for lots less than 8,000 square feet, fifty percent (50%) for lots between 8,000 and 9,000 square feet, forty-five percent (45%) for lots between ,9000 and 10,000 square feet, and forty percent (40%) for lots over 10,000 square feet. This standard will be Page 12 of 112 reviewed as part of the building permitting process to ensure compliance. Street and Sidewalk System There are two access points into the preliminary plat areas where Adamstown Drive and Aster Blvd intersect Akron Ave. There are two additional roads that are located internally, one of which runs north-south and connects to Adamstown Drive and Aster Blvd and the other road extends east off the north-south road to connect the 18th Addition to the 15th Additions preliminary plat area. Sidewalks are shown to be provided on at least one side of all streets in accordance with City policy, as well as an 8-foot trail that runs north to south along Akron Avenue. Parks The Parks and Recreation staff has reviewed the park dedication requirement for Amber Fields 15th Addition as part of the overall Master Development Plan to consider the multiple playgrounds and extensive open space within the development. The parks dedication for the 18th Addition will be met through developer installed improvements as outlined in the subdivision agreement. The street and sidewalk system within the preliminary plat provides direct access to the trails and parks. The Vermillion Highlands Regional Greenway is identified in the City’s Parks Master Plan as being in this area. The developer should work with the County to accommodate that trail. The County has indicated a willingness to acquire their required ROW using Met Council funds and has begun a dialogue with the developer. Landscaping and Tree Preservation The applicant's landscape plan provides one tree per interior lot and two on every corner lot, which meets the planting requirement of the landscaping ordinance. A tree inventory was conducted for the overall Amber Fields development area, and a total of 1,983 caliper inches of trees were identified for replacement following the formula laid out in the City Code. So far, 644.5 inches have been provided, which leaves an overall total of 1,338.5 caliper inches remaining to be replaced. Staff has discussed this with the developer, who has indicated the planting schedule for the open area in the center of the Amber Fields development will contain plantings more than that required by the tree preservation ordinance. A total of 76 trees will be planted within this development, therefore a landscaping surety in the amount of $25,080 (76 trees x $300 plus 10%) is required as a condition of approval. Utilities The site is served by water and sanitary sewer located within Akron Avenue. Stormwater is managed on site, which differs from previous additions located west of Akron Avenue. In that portion of Amber Fields, all stormwater is managed within the large open space central to the site. Storm sewers in both the Amber Fields 18th Addition and 15th Addition plat areas carry water to the basin located in the northern portion of the 15th additions preliminary plat area. There are also two temporary sediment basins located within the 18th addition. Engineering staff reviewed the proposed preliminary and final plat and provided a memorandum with comments generally related to plan details. Final Plat Standards for reviewing subdivision requests are detailed in Title 12 of the Rosemount City Code. This Page 13 of 112 section of the Code outlines the two-step Preliminary and Final Plat process for land subdivision. The final plat for Amber Fields 18th Addition contains 66 residential parcels as well as dedicated right of way. Additionally, the final plat contains one outlot called Outlot A. This outlot is located in the southernmost portion of the plat south of the 12 residential lots south of Adamstown Drive. Staff finds the Final Plat is consistent with the Preliminary Plat and meets the requirements of the Zoning Ordinance. RECOMMENDATION Staff is recommending approval of the rezoning and preliminary and final plats for Amber Fields 18th Addition, subject to conditions in the recommended action and contained within the Engineer’s memorandum. This recommendation is based on information provided by the applicant and reviewed in this report. Page 14 of 112 Page 15 of 112 CO U N T Y RO A D N O . 7 3 C. S. A. H. NO. 42 (145TH ST. W.)

Page 33 of 112 EXECUTIVE SUMMARY Planning Commission Regular Meeting: May 28, 2024 Tenative City Council Meeting: Unless the action taken tonight is appealed, this item will not go before the Council. AGENDA ITEM: Variance request by Kevin Moquin to construct an addition to an existing accessory structure that would exceed the maximum area allowed by the zoning ordinance. AGENDA SECTION: PUBLIC HEARINGS PREPARED BY: Anthony Nemcek , Senior Planner AGENDA NO. 6.b. ATTACHMENTS: Resolution, Site Location, Site Aerial, Oblique Aerial, Applicant's Submittal APPROVED BY: AK RECOMMENDED ACTION: Motion to adopt a resolution denying a variance from the R1-Low Density Residential standards to increase the maximum aggregate total for any accessory building(s), excluding attached garage, from one thousand (1,000) square feet to 1,816 square feet. or Motion to adopt a resolution approving a variance from the R1-Low Density Residential standards to increase the maximum aggregate total for any accessory building(s), excluding attached garage, from one thousand (1,000) square feet to 1,816 square feet. BACKGROUND Property Owner and Applicant Kevin Moquin Site Location 4101 143rd Street West Site Area 1.01 Acres Current Zoning R1-Low Density Residential Comp Plan Designation LDR-Low Density Residential Surrounding Use Residential The Community Development department received a variance request from the applicant to allow them to construct an addition to their existing detached garage that would result in a total area for the structure of 1,816 square feet. The maximum aggregate area, meaning the total area of all accessory structures, is limited to 1,000 square feet in the R1-Low Density Residential. The principal structure on the site was constructed in 1966, and the parcel on which it sits was platted in 2005 when the parcels immediately east of the subject parcel were split off and eventually sold. In addition to the principal structure, the subject property also contains a 1,000 square foot detached garage and a carport approximately 500 square feet in area. The carport was constructed sometime in the summer of 2018 and an addition to it was constructed in late 2019 or early 2020 based on aerial photos of the site. Therefore, the site already exceeds the maximum aggregate total of accessory structures. Page 34 of 112 The applicant initially met with staff when applying for a building permit. It was at that time staff informed the applicant that the subject property already exceeds the maximum square footage of accessory structures allowed by the City Code. Staff was unaware at that time when the carport was constructed, and staff assumed it was a legal non-conforming structure. Staff provided suggestions that an addition of the same square footage could replace the carport, or that the applicant could construct an attached garage that is a maximum of 1,000 square feet but can be up to 1,500 square feet so long as the garage does not exceed 50 percent of the gross floor area of the principal building (garage and living area combined). While researching and reviewing the variance request, no building permit records for the carport were found. Therefore, the carport is not legally non-conforming and a building permit for an addition to the garage could not be approved since the property is at its maximum allowable area of accessory structures even without the carport. Staff also informed the applicant that staff would be unable to make findings to support granting a variance and would have to recommend denial of the variance. To approve a variance request, five findings must be made in support of such an approval. In this case, only four findings can be made that would support the granting of a variance. Therefore, staff is recommending denial of the variance. If the Commission votes to adopt a resolution approving the variance, it must articulate its findings that support approval of the variance. Staff will then incorporate them into a resolution to be signed by the Chair following the meeting. An analysis of the request and staff's findings are detailed in this report. ISSUE ANALYSIS The Planning Commission, acting as the Board of Appeals and Adjustments, is being asked to consider a variance. The proposed variance is to increase the maximum aggregate total for any accessory building(s), excluding an attached garage, from one thousand (1,000) square feet to 1,816 square feet. Based on conversations with the applicant, it is staff's understanding that the applicant believes the large size of the lot means there will be minimal impact on neighboring properties and that increasing the amount of garage space on the property through the construction of an attached garage would change the look and feel of the property. While staff agrees that a large accessory building will likely not impact neighboring properties, it is staff's understanding of the intent of the ordinance is that the limit on the aggregate area of accessory buildings is to ensure the principal use on the site remains residential. There are no unique circumstances related to the property that would necessitate a variance, and the request is simply a matter of the applicant's desire for a larger detached garage. Also, because the carport was never permitted it is not considered a legally non-conforming use that could be replaced by a garage addition even if the applicant reduced the size of the proposed addition to match the existing carport. Staff received a comment from one resident within the notification area whose concern was that there have been vehicles parking on the street in front of the property when there were none parking before, and that the applicant is seeking to expand the detached garage to use it for a type of home- based business. Staff received no other comments related to the request. Variance Standards According to Section 11-12-2.G, there are five criteria for the Board of Appeals and Adjustments to review when considering a variance request. The five criteria used to assess each request along with staff’s findings for each are listed below. While weighing a variance request against these criteria, there are also two key issues to consider. The first is whether the applicant has reasonable use of their Page 35 of 112 property without the variance. The second is whether the project can be redesigned to eliminate or reduce the need for a variance. The Board of Zoning Appeals must approve or deny each request based on findings related to each of the five standards. 1. The variance request is in harmony with the purposes and intent of the ordinance. Finding: While detached garages are a permitted accessory use in the R1 zoning district, it is staff's interpretation that the intent of the ordinance to limit the total aggregate area of accessory structures is to ensure that the principal use on the site remains residential. Because the footprint of the house is larger than the proposed detached garage and addition, staff finds the variance request to be in harmony with the purpose and intent of the ordinance. 2. The variance is consistent with the comprehensive plan. Finding: The site is designated as Low Density Residential. The variance request is consistent with that designation. 3. The property owner proposes to use the property in a reasonable manner. Finding: Staff finds that, given the information received from the applicant, the property owner proposes to use the property in a reasonable manner. That being said, if there is an intention by the property owner to make use of the detached garage for anything other than the storage of vehicles or personal use, staff would not find that reasonable. 4. There are unique circumstances to the property which are not created by the landowner. Finding: Staff does not find any unique circumstances to the property that would necessitate a variance in order for the applicant to have reasonable use of the property. If it is the desire of the applicant to have additional garage space, they are permitted to construct an attached garage of 1,000 square feet and up to 1,500 square feet so long as the garage does not exceed 50 percent of the gross floor area of the principal building (garage and living area combined). The applicant acknowledges the subject parcel is larger than most, and there would be no issues meeting the lot standards related to setbacks and lot coverage 5. Granting of the variance does not alter the essential character of the locality. Finding: The essential character of the locality would not be altered by granting the variance. A single family home with a detached garage is consistent with the character and residential nature of the locality. RECOMMENDATION Because staff finds no unique circumstances that would require a variance from the maximum aggregate total for accessory buildings in the R1 zoning district in order to have reasonable use of the subject parcel, staff is recommending denial of the variance request.

BACKGROUND Applicant 814 Services, LLC Property Owner Akron 42, LLC Site Location Directly north of 145th Street West (County Road 42) and in-between Akron Avenue and Abbeyfield Avenue Site Area In Acres Approximately 1.44 Acres Current Zoning C4-General Commercial Comp Plan Designation CC - Community Commercial Page 51 of 112 The Planning Commission is being asked to review the site plan submitted by 814 Services, LLC to construct an 11,093 square foot childcare center with a 10,786 square foot play area on a 1.44-acre site located directly north of 145th Street West (County Road 42) and in-between Akron Avenue and Abbeyfield Avenue. The subject parcel is located within the recently approved Prestwick Place 25th Addition plat area. The plans provided by the applicant generally meet all requirements of the zoning ordinance within the City Code with the exception being the ratio of building materials used. Staff is recommending approval of the site plan review to allow for the construction of the childcare center, subject to the conditions listed in the recommended action section above. GENERAL INFORMATION The subject property is part of the Prestwick Place Planned Unit Development that was originally approved in 2007. It is designated in the City’s comprehensive land use plan for commercial uses and has been zoned accordingly since the original PUD approval. The original PUD approval was very prescriptive about how this area would develop. For example, the PUD described the specific types of commercial uses, as well as the size of the buildings that would be permitted on the parcels. That was much more specific than seen in any of the planned unit developments that have been approved since, and it was very limiting as to the type of commercial development that could occur. A Major PUD Amendment was approved that removed the subject property, as well as other adjacent undeveloped outlots from the scope of the Commercial Area Guidelines within the 2007 PUD agreement. Additionally, land immediately north of the subject parcel was reguided from CC-Community Commercial to HDR-High Density Residential in order to help provide a critical mass of residents that would not otherwise support commercial development due to the large swaths of open land held by Flint Hills Resources and the University of Minnesota within the market area used to determine the feasibility of commercial projects by developers. The City Council recently approved a preliminary and final plat for Prestwick Place 25th Addition which created two buildable lots, one of those lots being the subject parcel. This land was previously outloted with Prestwick Place 24th Addition for future commercial use. A bank and coffee shop were also recently approved on land directly west of this subject site and there is anticipation of an application submittal for commercial development for the land directly east of the subject site. Childcare centers are permitted uses in the C4-General Commercial zoning district. In addition to the general site plan, the applicant has provided architectural drawings, a grading plan, a utility plan, and a landscape plan, all of which are included in the attachments. A formal review and analysis of this information and how it relates to the Zoning Ordinance is provided in the next section. No variances are being requested for the construction of the addition, and subject to the conditions listed above, the proposed development meets the requirements of the zoning ordinance. SITE PLAN REVIEW The purpose of a site plan review is to evaluate each project as it relates to the performance and site design standards of the zoning ordinance. Site plan approval is required for all commercial, industrial, institutional and multi-family development projects. Site plan applications are approved by the Planning Commission and considered a quasi-judicial action. As such, the City has a set of standards and requirements for review. Generally, if a site plan Page 52 of 112 application meets the ordinance requirements, it must be approved. These standards are outlined in Section 11-4-14 (General Commercial District) and 11-10-3 (Site and Building Plan Review). Setbacks The proposed building is shown to be located in the southern portion of the subject parcel with the main entrance facing towards the west. The north and west portions of the site contain parking lot areas and drive aisles. The southern and eastern portions of the site contain the proposed play area, which is shown to be fenced in with a 6-foot fence. The table below shows the required setbacks in comparison with those provided on the site plan. The table includes an additional setback of 20’ from CSAH 42, an arterial road, for structures. Required Setback Provided Setback Frontage Building Parking Building Parking North 10 feet 10 feet >10 feet >10 feet East 10 feet 10 Feet 36 feet 15 feet South (CSAH 42) 30 feet 20 feet 67 feet >20 feet West 10 feet 10 feet 48 feet 24 feet The site plan also shows a trash enclosure southwest of the proposed building and directly west of the play area. The enclosure is shown to be setback 10-feet from the western property line and more than 30-feet from the southern property line, which meets the setback requirements of the city code. All building setbacks meet ordinance requirements. The setback for parking from the west property line is ten (10) feet. The drive aisle is not included in the setback for parking as the parking and drive aisles will flow into the parking on the site to the west. Parking and Access There will be two vehicular accesses into the site, one from the private road that runs east-west between Akron Avenue and Abbeyfield Avenue and the other from an internal drive access which will eventually connect to the commercial development to the east. The access to the site from the east west private road will extend south to the site. This access will be shared with the commercial development to the west. There is a concrete median shown on the western property line, which is where the shared access road into the site is located. A requirement of the City’s Engineering memorandum is for the applicant to provide turning movements for emergency, delivery, and garbage vehicles as there is a potential issue with the location of the concrete median. Traffic is shown to circulate to the west and north of the principal structure with parking located within those areas. The parking requirement for a childcare center is 1 parking stall per 20 children, plus one parking stall per staff member. Based on the number of children the facility will be able to accommodate and required staffing for that number of children (157 students and 26 staff members), a total of 34 parking stalls are required. The site plan includes 40 stalls, 2 of which are ADA compliant stalls, which exceeds the required number of parking stalls. Page 53 of 112 Use Required Provided Daycare Centers, Nursery and Montessori schools 34 Stalls (1 per 20 children plus 1 per staff) 40 Stalls Exterior Building Materials and Massing The building elevations provided show a mix of materials being used on the exterior. Brick will extend along the base of the entire building. Horizontal lap siding makes up the remainder of the exterior siding on the building. The front entrance to the building shows two colorful aluminum tubes along with two concrete sphere bollards. No EIFS or masonry stucco, of which 10% of the façade can be comprised, will be used. The C4-General Commercial zoning district has a requirement that at least 50% of the exterior must contain natural stone or brick. The elevations do not meet that minimum threshold which the applicant is aware of, and new plans will be submitted prior to City Council approval to meet that requirement. Staff will be recommending a condition of approval that calls for the submittal of updated elevations that increase the amount of natural stone or brick to the 50% threshold. The tallest portion of the building is shown to be 24’9” in height. This is below the maximum building height of 35’ allowed in the C4 zoning district. Trash Enclosure A 7-foot-tall trash enclosure featuring materials such as split-face concrete masonry units and precast concrete cap with gates on the enclosure shown to be made of composite lumber. The enclosure will be located in the southern portion of the site, south of the western parking area and west of the enclosed play area. Fencing Fences are approved administratively by staff. They can be constructed up to, but not on, the property line. In non-residential zoning districts, the maximum fence height is 8’. The applicants' plans show fencing surrounding the 10,786 square foot outdoor play area which is located on the south and east sides of the proposed building. The fence is shown to be 6-feet tall on the applicants' site plan. Landscaping The City’s landscape ordinance (11-6-3) requires that properties within the commercial zoning districts plant a minimum of 8 trees or 1 per 3,000 square feet of land area. Based on the site area of 62,726 square feet, a total of 21 trees are required to be planted on site. The applicants site plan shows a total of 11 trees planted throughout the site, which is below the required number. The landscape plan shows the tree calculation based off a plantable landscape area of 5,370 square feet instead of the total 62,726 square feet of the site. The landscaping ordinance also requires one foundation plating for every 10 linear feet of building exterior. The proposed building has 500 linear feet of perimeter, which requires a total of 50 foundation plantings. The landscape plan includes 50 total foundation plantings which are shown to be located along the front of the building, near the trash enclosure on the southern end of the site and along the northern parking lot area. Turf sod is also shown to be installed along the southern, wester, and northern portions of the site. In addition to the landscaping required by the City’s landscaping ordinance, the C4-General commercial zoning district requires a certain level of landscaping in parking lot areas. A minimum of 10% of the site's parking areas must be landscaped, and within the landscaping section of the zoning code. The parking area on site totals 6,480 square feet, which equates to a landscaped area of 648 square feet. Page 54 of 112 Based on that square footage, 3 trees (1 per 250 square feet) must be planted in the parking area. The applicants' plan shows 3 trees planted throughout the northern parking area. Overall, the landscape plan falls short of the minimum requirement by the city’s code, and a condition of approval to provide additional trees on the landscaping plan is included in staff’s recommendation. Calculation Formula Number Required Number Provided Site Trees 8 trees or 1 per 3,000 sf 62,726/3,000=21 trees 8 trees Parking Lot Landscaping 1 per 250 sf 648/250=3 trees 3 trees Foundation Plantings 1 per 10 linear feet 500/10=50 foundation plants 50 foundation plants Lighting The applicant is proposing site lighting that consists of three pole mounted lights within the parking lot area. The pole mounted lights are shown to be 25-feet in height. The zoning ordinance allows pole mounted lights to be up to 30-feet tall except in areas within 100-feet of a residential use. In those areas, the maximum height for lighting is 20-feet. The maximum level of lighting allowed by the code is 0.5 lumen at adjacent residential property lines and 1.0 lumen at non-residential property lines. The applicant has informed staff that the closest pole mounted light from the northern residential property boundary is 121-feet. The applicant has submitted a photometric study, but they will be resubmitting an expanded photometric plan showing that the lumen levels do not exceed 0.5 lumen at the northern property boundary. Park Dedication The developer of the Prestwick Place 25th Addition plat had requested that park dedication fees be collected at the time a building permit was issued. The park dedication requirement for commercial developments is either 10% of the total property area as land dedication or cash-in-lieu of land dedication. The cash dedication for the 1.44-acre site is $12,960 (.144 acres x $90,000/acre). Staff has included the payment of the park dedication fee with the building permit fee as a recommended condition of approval. Engineering The City’s engineer has reviewed the submitted plans and provided a memorandum dated May 17, 2024. The memo contains general comments related to the site plan, grading and drainage plan, and utility plans. Some key comments within the document include: providing turning movements for emergency, delivery, and garbage vehicles, working with the landowner to the west to coordinate shared access into both sites and to coordinate utility installations and extensions. Conformance with all requirements of the City Engineer is a recommended condition of approval. RECOMMENDATION Staff finds the plans provided by the applicant meet the standards of the zoning ordinance except where noted, and is recommending approval of the site plan allowing 814 Services, LLC, to construct a childcare center. This recommendation is based on information provided by the applicant and reviewed in this report.

Subsequently, Joint Trench and Home construction will occur. TOTAL PLATTED AREA: 1.44 AC TOTAL DISTURBED AREA: 1.44 AC PROPOSED (DESIGN) IMPERVIOUS AREA:0.81 AC SPECIAL WATERS: The site is NOT within a 1-mile radius of a special or impaired water. CONSTRUCTION PHASING The project is expected to be constructed in three phases, with mass grading occurring during one construction season. Mass grading is anticipated to be completed within 4 weeks from commencement of work. Utility and street construction is anticipated to be completed within 4 weeks from commencement of work. POTENTIONAL FOR EROSION AND DISCHARGE OF SEDIMENT As the site will be stripped of topsoil and vegetation for a period of several weeks during construction, the potential for erosion will increase. The overall gradients on the site are relatively low. The street subcut will serve as temporary sediment basins during construction. The project is primarily cut, and therefore perimeter erosion will flow inward towards the project. The risk of discharge of sediment off of the site is low, due to the grade orientation and design. The highest potential for discharge off the site is from the street entrance. Contractor will be required to manage completion of 3:1 slopes such that soil exposure is minimized. After excavation and embankments are completed, slopes shall be re-spread with topsoil, the slope grades certified, and erosion blanket installed as per the plan. Contractor shall coordinate these steps to be carried out in a timely manner. EROSION CONTROL BMPs The construction plans anticipate the use of, but are not limited to, the following Erosion Control BMPs: 1.Perimeter delineation to minimize disturbed areas 2.Temporary Rock Construction Entrance 3.Temporary straw mulch as needed. 4.Seed and mulch/sod 5.Erosion Control Blanket 6.Minimize active or disturbed work areas 7.Horizontal slope grading 8.Turf Reinforcement Mat SEDIMENT CONTROL BMPs The construction plans anticipate the use of, but are not limited to, the following Sediment Control BMPs 1.Sediment traps constructed in street subcut 2.Rock filter dikes in street subcut 3.Utilize permanent stormwater basin as Temporary Sediment Basin 4.Silt Fence at project perimeter or toe of slopes 5.Inlet protection on existing catch basins 6.Inlet protection on existing culverts 7.Inlet protection after utility construction 8.Linear control along back of new curb and gutter (sod, bioroll, or silt fence) 9.Routine street sweeping adjacent to construction entrance. 10.Ditch checks Refer to plans for designated locations of BMPs, details and implementation notes. BASIN AND TRAP DEWATERING BMPs Should the need arise for basin or trap dewatering, contractor shall utilize a floating skimmer pump intake, such that the water is drawn from the surface of the basin. Pumped effluent shall not be discharged into Surface Waters in a turbid state. Turbid effluent shall be filtered with mechanical devices, chemical filtering, or a combination thereof, to a state of 50 NTUs or less. STABILZATION BMPs The construction plans anticipate the use of, but are not limited to, the following Stabilization BMPs: 1.After lot pads are grade certified, permanent seed and mulch can be applied, generally from the front of the building pad, extending to the rear of the lot (areas where no further utility construction is anticipated.) 2.After 3:1 slopes on lots are certified, permanent seed and erosion control blanket can be applied. 3.Rip rap at pipe outfalls 4.Permanent seed and erosion control blanket on basin slopes after grade certified. 5.After curbs are backfilled, apply permanent seed and mulch to remaining building pads and boulevard area not already stabilized. 6.Sod placement, as appropriate. POLLUTION CONTROL BMPs 1.Fueling: A fixed fueling station is not anticipated. Contractor will be required to implement BMPs for onsite re-fueling of equipment. 2.Concrete Washout: A suggested washout area will be specified on the plan. The developer has the ability to adjust location or to provide alternative washout containment. 3.There is not an anticipated need for storing chemicals, paints, solvents or other potentially toxic or hazardous materials on site. SEED & MULCH SPECIFICATIONS Seed placed for permanent cover or final stabilization requires 6” minimum topsoil cover. Exception: Infiltration basins - see basin details for soil type). Multiple site visits will be required to accommodate permanent or temporary stabilization as required during the phases of construction.

If rock becomes filled with sediment and tracked material to the extent the purpose ceases to function, remove the contaminated rock and replace with new rock. 2.Silt fence - Inspect weekly, particularly for damaged sections, breaches, down-gradient areas, flow concentration points, scour areas and sections adjacent to sensitive areas. Where capacity is filled to more than 50% of depth, sediment shall be removed to restore capture capacity. 3.Sediment traps and basins - Inspect weekly. Where capacity is filled to more than 50% of depth, sediment shall be removed to restore capture capacity within 72 hours of discovery. 4.Inlet Protection - Inspect weekly or more frequently as needed after multiple rainfalls less than 0.5”. Verify intake capacity is not compromised. Where capacity is filled to more than 50% of depth, sediment shall be removed to restore capture capacity. 5.Inspect other site specific BMP's on a weekly basis minimum. Rain Event Inspection - Mandatory, within 24 hours after a rain event 0.5” or greater. Complete all items associated with Routine Inspection. Furthermore, inspect site for breaches, failures, scours and gullying. Take corrective actions as necessary to restore functionality to the BMP's. If a given situation is discovered to be prone to repetitive failure, advise the Engineer and Contractor for SWPPP and BMP amendments. ADDITIONAL SWPPP NOTES 1.All Erosion and Sediment Control facilities shall be maintained by the contractor during the construction operations. Any temporary facilities which are to be removed as called for on these plans and specifications shall be removed by the contractor at the time directed by the engineer. The contractor shall then restore the subsequently disturbed areas in accordance with these plans and specifications. 2.Wherever practical and feasible, the contractor shall protect and preserve existing natural trees, grass and other vegetative cover in effort to provide natural buffering and filtering of runoff. 3.Contractor shall be adaptable in adjusting construction schedules in anticipation of weather forecasts of precipitation, in order to minimize risk of erosion and sediment transport. 4.It is the responsibility of the contractor to keep public streets, travel ways, parking lots and trails utilized for ingress to and egress from the construction site free of dirt, sediment and debris, resulting from construction activity. Cost for this shall be considered incidental to the contract. 5.Adequate control of dust shall be maintained by the contractor. Cost for dust control shall be considered incidental to the contract. ADDITIONAL SWPPP NOTES (continued) 6. Perimeter controls shall not be removed until final stabilization of areas draining toward the control devices. 7. When temperatures do not exceed 40 degrees F, areas that require seed and mulch stabilization shall be dormant seeded. Application rate shall be two times the normal rate. No dormant seeding shall be done on ice or snow greater than 2” in depth. 8. Any areas that were seeded that do not achieve 70% coverage shall be reseeded at the contractor's expense, where coverage limitation is caused by lack of seed germination and growth. MPCA STORMWATER PERMIT - RESPONSIBILITY The Contractor will be required to become the Permittee for the project, until final stabilization and transfer of responsibility is completed. Transfer of responsibility shall be completed with the Permit Modification Form.

R. 7090] 2.8 This permit does not replace or satisfy any environmental review requirements including those under the Minnesota Environmental Policy Act or the National Environmental Policy Act. The owner must verify completion of any environmental review required by law, including any required Environmental Assessment Work Sheets or Environmental Impact Statements, Federal environmental review, or other required review prior to applying for coverage under this permit. If any part of your common plan of development or sale requires environmental review, coverage under this permit cannot be obtained until such environmental review is complete. [Minn. R. 7090] 2.9 This permit does not replace or satisfy any review requirements for discharges adversely impacting State or Federally designated endangered or threatened species or a designated critical habitat. The owner must comply with the National Historic Preservation Act and conduct all required review and coordination related to historic preservation, including significant anthropological sites and any burial sites, with the Minnesota Historic Preservation Officer. [Minn. R. 7090] 2.10 This permit does not authorize discharges to wetlands unless the permittee complies with the requirements in Section 22. Coverage under this permit cannot be issued until the requirements for wetland permits, decisions, other determinations, or the mitigative sequence required in section 22 have been finalized and documented. [Minn. R. 7050.0186] 3.1 Application and Coverage Effective Date. [Minn. R. 7090] 3.2 The owner and operator must submit a complete and accurate on-line application with the appropriate fee to the MPCA for each project that disturbs one (1) or more acres of land or for a common plan of development or sale that will ultimately disturb one (1) or more acres. [Minn. R. 7090] 3.3 For projects or common plans of development or sale that disturb less than 50 acres or do not discharge stormwater within 1 mile (aerial radius measurement) of a special or impaired water, permittees do not need to submit the SWPPP with the application. Permit coverage for these projects is effective upon application and completing the payment process. [Minn. R.7090] 3.4 For certain projects or common plans of development or sale disturbing 50 acres or more, the complete SWPPP must be included with the application and submitted at least 30 days before the start of construction activity. This applies if there is a discharge point on the project within one mile (aerial radius measurement) of, and flows to, a special water listed in item 23.3 through 23.6 or an impaired water as described in item 23.7. Permit coverage for these projects is effective upon submitting the application and complete SWPPP, completing the payment process and receiving a determination from the MPCA that the review of the SWPPP is complete. The determination may take longer than 30 days if the SWPPP is incomplete. If the MPCA fails to contact the permittees within 30 days of application receipt, coverage is effective 30 days after completing the payment process. [Minn. R. 7090] 3.5 The application requires listing all persons meeting the definition of owner and operator as permittees. The owner is responsible for compliance with all terms and conditions of this permit. The operator is responsible for compliance with Sections 3, 4, 6-22, 24 and applicable requirements for construction activity in Section 23. [Minn. R. 7090] 3.6 Permittees will receive coverage notification in a manner determined by the MPCA. [Minn. R. 7090] 3.7 For construction projects where the owner or operator changes (e.g., an original developer sells portions of the property to various homebuilders or sells the entire site to a new owner), the current owner and the new owner or operator must submit a complete permit modification form provided by the MPCA. The current owner and the new owner or operator must submit the form prior to the new owner or operator commencing construction activity or no later than 30 days after taking ownership of the property. [Minn. R. 7090] 3.8 For construction projects where the owner or operator changes, the current owner must provide a SWPPP to the new owner and operator that specifically addresses the remaining construction activity. The new owner or operator can implement the original SWPPP, modify the SWPPP, or develop a new SWPPP. Permittees must ensure their activities do not render another party's erosion prevention and sediment control BMPs ineffective. [Minn. R. 7090] 4.1 Termination of Coverage. [Minn. R. 7090] 4.2 Permittees must submit a NOT within 30 days after all termination conditions listed in Section 13 are complete.[Minn. R. 7090] 4.3 Permittees must submit a NOT within 30 days after selling or otherwise legally transferring the entire site, including permit responsibility for roads (e.g., street sweeping) and stormwater infrastructure final clean out, or transferring portions of a site to another party. The permittees' coverage under this permit terminates at midnight on the submission date of the NOT.[Minn. R. 7090] 4.4 Permittees may terminate permit coverage prior to completion of all construction activity if they meet all of the following conditions: a.construction activity has ceased for at least 90 days; and b.at least 90 percent (by area) of all originally proposed construction activity has been completed and permanent cover has been established on those areas; and c.on areas where construction activity is not complete, permanent cover has been established; and d.the site complies with item 13.3 through 13.7. After permit coverage is terminated under this item, any subsequent development on the remaining portions of the site will require permit coverage if the subsequent development itself or as part of the remaining common plan of development or sale will result in land disturbing activities of one (1) or more acres in size. [Minn. R. 7090] 4.5 Permittees may terminate coverage upon MPCA approval after submitting information documenting the owner cancelled the project. [Minn. R. 7090] 5.1 Stormwater Pollution Prevention Plan (SWPPP) Content. [Minn. R. 7090] 5.2 The owner must develop and implement a SWPPP. The SWPPP must include items 5.3 through 5.26. [Minn. R. 7090] 5.3 The SWPPP must incorporate specific Best Management Practices (BMP) used to comply with the requirements of this permit. [Minn. R. 7090] 5.4 The SWPPP must include a narrative describing the timing for installation of all erosion prevention and sediment control BMPs and a description of the permanent stormwater treatment systems. [Minn. R. 7090] 5.5 The SWPPP must include the location and type of all temporary and permanent erosion prevention and sediment control BMPs along with procedures used to establish additional temporary BMPs as necessary for the site conditions during construction. Standard details and/or specifications for BMPs must be included in the final plans and specifications for the project. [Minn. R. 7090] 5.6 The SWPPP must include the calculations and other information used for the design of temporary sediment basins and any of the permanent stormwater treatment systems required in Section 15. [Minn. R. 7090] 5.7 The SWPPP must include estimated quantities anticipated at the start of the project for the life of the project for all erosion prevention and sediment control BMPs (e.g., linear feet of silt fence or square feet of erosion control blanket). [Minn. R. 7090] 5.8 The SWPPP must include the number of acres of impervious surface for both pre- and post-construction. [Minn. R. 7090] 5.9 The SWPPP must include a site map with existing and final grades, including drainage area boundaries, directions of flow and all discharge points where stormwater is leaving the site or entering a surface water. The site map must indicate the areas of steep slopes. The site map must also include impervious surfaces, soil types and locations of potential pollutant- generating activities as identified in Section 12. [Minn. R. 7090] 5.10 The SWPPP must include a map of all surface waters, existing wetlands, and stormwater ponds or basins that can be identified on maps such as United States Geological Survey 7.5-minute quadrangle maps, the National Wetland Inventory map or equivalent maps and are within one mile (aerial radius measurement) from the project boundaries that will receive stormwater from the construction site, during or after construction. The SWPPP must identify if the surface waters are special or impaired waters. [Minn. R. 7090] 5.11 The SWPPP must include a site map showing construction activity areas that are adjacent to and drain to Public Waters for which the DNR has promulgated "work in water restrictions" during specified fish spawning time frames. [Minn. R. 7090] 5.12 Permittees must identify locations of 50' buffer zones as required in item 9.17 and 100' permanent buffer zones as required in item 23.11, on plan sheets in the SWPPP. [Minn. R. 7090] 5.13 If permittees determine compliance with the following requirements is infeasible, they must document the determination in the SWPPP: a.temporary sediment basins as described in Section 14; and b.for linear projects, if the permanent stormwater treatment system cannot be constructed within the right-of-way, a reasonable attempt must be made to obtain additional right-of-way (item 15.9); and c.buffer zones as described in item 9.17 and item 23.11. [Minn. R. 7090] 5.14 If permittees determine that a temporary sediment basin is infeasible as described in item 14.10, the SWPPP must describe the alternative BMPs used. [Minn. R. 7090] 5.15 Where systems cannot meet the full volume reduction requirement on-site, (e.g., the site has infiltration prohibitions, see item 16.14 through item 16.21) the permittee must document the reasons in the SWPPP. [Minn. R. 7090] 5.16 The SWPPP must include any stormwater mitigation measures proposed to be part of the final project in any environmental review document, endangered species review, archeological or other required local, state or federal review conducted for the project. For purposes of this permit, mitigation measures mean actions necessary to avoid, minimize, or mitigate for impacts related to erosion prevention, sediment control, the permanent stormwater treatment system, pollution prevention management measures and discharges associated with the project's construction activity. [Minn. R. 7090] 5.17 The SWPPP must describe the methods used for permanent cover of all exposed soil areas. [Minn. R. 7090] 5.18 Permittees must identify the locations of areas where construction will be phased to minimize the duration of exposed soil areas in the SWPPP. [Minn. R. 7090] 5.19 For projects with a discharge point on the project within one (1) mile (aerial radius measurement) of and which flows to an impaired water, permittees must identify the impaired water(s), and any United States Environmental Protection Agency (USEPA)-approved Total Maximum Daily Load (TMDL) for the pollutant(s) or stressor(s) described in item 23.7. Permittees' identification must include those TMDLs approved at any time prior to permit application submittal and are still in effect. [Minn. R. 7090] 5.20 Permittees must document in the SWPPP, all trained individuals identified in item 21.2. Documentation must include: a.names of personnel required to be trained; and b.dates of training and name of instructor(s) and entity providing training; and c.content of training course. If permittees do not know the names of the individuals at the time of application, the permittees must ensure they document training before construction activity commences. [Minn. R. 7090] 5.21 The SWPPP must identify a person knowledgeable and experienced in the application of erosion prevention and sediment control BMPs who will coordinate with all contractors, subcontractors, and operators on-site to oversee the implementation of the SWPPP. [Minn. R. 7090] 5.22 The SWPPP must describe any specific chemicals and chemical treatment systems used for enhancing the sedimentation process and how it achieves compliance with item 9.19. [Minn. R. 7090] 5.23 The SWPPP must identify the person(s), organizations, or entities responsible for long-term operation and maintenance of permanent stormwater treatment systems. [Minn. R. 7090] 5.24 The SWPPP must describe methods to minimize soil compaction and preserve topsoil. Minimizing soil compaction is not required where the function of a specific area dictates compaction. [Minn. R. 7090] 5.25 The SWPPP must include any site assessments for groundwater or soil contamination required in item 16.15.[Minn. R. 7090] 5.26 The SWPPP must account for the following factors in designing temporary erosion prevention and sediment control BMPs: a.the expected amount, frequency, intensity, and duration of precipitation; and b.the nature of stormwater runoff and run-on at the site, including factors such as expected flow from impervious surfaces, slopes, and site drainage features; and c.the stormwater volume, velocity, and peak flowrates to minimize discharge of pollutants in stormwater and to minimize channel and streambank erosion and scour in the immediate vicinity of discharge points; and d.the range of soil particle sizes expected to be present. [Minn. R. 7090] 6.1 SWPPP Amendments. [Minn. R. 7090] 6.2 One of the individuals described in item 21.2.a or item 21.2.b or another qualified individual must complete all SWPPP changes. Changes involving the use of a less stringent BMP must include a justification describing how the replacement BMP is effective for the site characteristics. [Minn. R. 7090] 6.3 Permittees must amend the SWPPP within 7 days to include additional or modified BMPs whenever there is a change in design, construction, operation, maintenance, weather or seasonal conditions having a significant effect on the discharge of pollutants to surface waters or groundwater. [Minn. R. 7090] 6.4 Permittees must amend the SWPPP within 7 days to include additional or modified BMPs whenever inspections or investigations by the site owner or operator, USEPA or MPCA officials indicate the SWPPP is not effective in eliminating or significantly minimizing the discharge of pollutants to surface waters or groundwater or the discharges are causing water quality standard exceedances (e.g., nuisance conditions as defined in Minn. R. 7050.0210, subp. 2) or the SWPPP is not consistent with the objectives of a USEPA approved TMDL. [Minn. R. 7050.0210] 7.1 BMP Selection and Stormwater Management. [Minn. R. 7090] 7.2 Permittees must select, install, and maintain the BMPs identified in the SWPPP and in this permit in an appropriate and functional manner and in accordance with relevant manufacturer specifications and accepted engineering practices to minimize the discharge of pollutants in stormwater from construction activities. Examples of stormwater management practices for this section include but are not limited to wet sedimentation basins, temporary depressions to hold stormwater, stormwater routing, dikes, berms, pumping, and stormwater treatment BMPs. Permittees must phase and incorporate stormwater management principles as the construction progresses. Unless infeasible, temporary or permanent wet sedimentation basins (when required, see section 14 and 15) should be constructed as a first step in the process and stormwater routed to these. [Minn. R. 7090] 7.3 Permittees must not disturb more land (i.e., phasing) than can be effectively inspected and maintained in accordance with Section 11. [Minn. R. 7090] 7.4 If permittees will be using some type of erosion control netting on the site as part of the soil stabilization techniques, permittees are encouraged to use products that have been shown to minimize impacts on wildlife. The U.S. Fish & Wildlife Service recommends using types of netting practices that are considered "wildlife friendly," including those that use natural fiber or 100 percent biodegradable materials and that use a loose weave with a non-welded, movable jointed netting. Products that are not wildlife friendly include square plastic netting that are degradable (e.g., photodegradable, UV- degradable, oxo-degradable), netting made from polypropylene, nylon, polyethylene, or polyester. Other recommendations include removing the netting product when it is no longer needed. More information may be found at: https://www.fws.gov/initiative/protecting-wildlife/make-change-wildlife-friendly-erosion-control-products. There also may be State, Tribal, or local requirements about using wildlife friendly erosion control products. See Minnesota Department of Transportation requirements at: https://www.mndot.org/environment/erosion/rolled-erosion-prevention-products.html. [Minn. R. 7050] 8.1 Erosion Prevention Practices. [Minn. R. 7090] 8.2 Before work begins, permittees must delineate the location of areas not to be disturbed. [Minn. R. 7090] 8.3 Permittees must minimize the need for disturbance of portions of the project with steep slopes. When steep slopes must be disturbed, permittees must use techniques such as phasing and stabilization practices designed for steep slopes (e.g., slope draining and terracing). [Minn. R. 7090] 8.4 Permittees must stabilize all exposed soil areas, including stockpiles. Stabilization must be initiated immediately to limit soil erosion when construction activity has permanently or temporarily ceased on any portion of the site and will not resume for a period exceeding 14 calendar days (7 days for sites discharging to special or impaired waters, see section 24). Stabilization must be completed no later than 14 calendar days after the construction activity has ceased. Stabilization is not required on constructed base components of roads, parking lots and similar surfaces. Stabilization is not required on temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand stockpiles) but permittees must provide sediment controls at the base of the stockpile. [Minn. R. 7090] 8.5 For Public Waters that the Minnesota DNR has promulgated "work in water restrictions" during specified fish spawning time frames, permittees must complete stabilization of all exposed soil areas within 200 feet of the water's edge, and that drain to these waters, within 24 hours during the restriction period. [Minn. R. 7090] 8.6 Permittees must stabilize the normal wetted perimeter of the last 200 linear feet of temporary or permanent drainage ditches or swales that drain water from the site within 24 hours after connecting to a surface water or property edge. Permittees must complete stabilization of remaining portions of temporary or permanent ditches or swales within 14 calendar days (7 days for sites discharging to special or impaired waters, see section 24) after connecting to a surface water or property edge and construction in that portion of the ditch temporarily or permanently ceases. [Minn. R. 7090] 8.7 Temporary or permanent ditches or swales being used as a sediment containment system during construction (with properly designed rock-ditch checks, bio rolls, silt dikes, etc.) do not need to be stabilized. Permittees must stabilize these areas within 24 hours after their use as a sediment containment system ceases. [Minn. R. 7090] 8.8 Permittees must not use mulch, hydromulch, tackifier, polyacrylamide or similar erosion prevention practices within any portion of the normal wetted perimeter of a temporary or permanent drainage ditch or swale section with a continuous slope of greater than 2 percent. Examples of acceptable erosion prevention practices include blankets, poly, riprap, etc. [Minn. R. 7090] 8.9 Permittees must provide temporary or permanent energy dissipation at all pipe outlets within 24 hours after connection to a surface water or permanent stormwater treatment system. [Minn. R. 7090] 9.1 Sediment Control Practices. [Minn. R. 7090] 9.2 Permittees must establish sediment control BMPs on all downgradient perimeters of the site and downgradient areas of the site that drain to any surface water, including curb and gutter systems. Permittees must locate sediment control practices upgradient of any buffer zones. Permittees must install sediment control practices before any upgradient land-disturbing activities begin and must keep the sediment control practices in place until they establish permanent cover. [Minn. R. 7090] 9.3 If downgradient sediment controls are overloaded, based on frequent failure or excessive maintenance requirements, permittees must install additional upgradient sediment control practices or redundant BMPs to eliminate the overloading and amend the SWPPP to identify these additional practices as required in item 6.3. [Minn. R. 7090] 9.4 Temporary or permanent drainage ditches and sediment basins designed as part of a sediment containment system (e.g., ditches with rock-check dams) require sediment control practices only as appropriate for site conditions. [Minn. R. 7090] 9.5 A floating silt curtain placed in the water is not a sediment control BMP to satisfy item 9.2 except when working on a shoreline or below the waterline. Immediately after the construction activity (e.g., installation of rip rap along the shoreline) in that area is complete, permittees must install an upland perimeter control practice if exposed soils still drain to a surface water.[Minn. R. 7090] 9.6 Permittees must re-install all sediment control practices adjusted or removed to accommodate short-term activities such as clearing or grubbing, or passage of vehicles, immediately after the short-term activity is completed. Permittees must re- install sediment control practices before the next precipitation event even if the short-term activity is not complete. [Minn. R. 7090] 9.7 Permittees must protect all storm drain inlets using appropriate BMPs during construction until they establish permanent cover on all areas with potential for discharging to the inlet. [Minn. R. 7090] 9.8 Permittees may remove inlet protection for a particular inlet if a specific safety concern (e.g. street flooding/freezing) is identified by the permittees or the jurisdictional authority (e.g., city/county/township/Minnesota Department of Transportation engineer). Permittees must document the need for removal in the SWPPP. [Minn. R. 7090] 9.9 Permittees must provide silt fence or other effective sediment controls at the base of stockpiles on the downgradient perimeter prior to the initiation of stockpiling. Sediment controls must be managed in accordance with section 9.6. [Minn. R. 7090] 9.10 Permittees must locate stockpiles outside of natural buffers or surface waters, including stormwater conveyances such as curb and gutter systems unless there is a bypass in place for the stormwater. [Minn. R. 7090] 9.11 Permittees must install a vehicle tracking BMP to minimize the track out of sediment from the construction site or onto paved roads within the site. [Minn. R. 7090] 9.12 Permittees must use street sweeping in addition to vehicle tracking BMPs if vehicle tracking BMPs alone are not adequate to prevent sediment tracking onto the street. [Minn. R. 7090] 9.13 Permittees must install temporary sediment basins as required in Section 14. [Minn. R. 7090] 9.14 In any areas of the site where final vegetative stabilization will occur, permittees must restrict vehicle and equipment use to minimize soil compaction. [Minn. R. 7090] 9.15 Permittees must preserve topsoil on the site, unless infeasible. [Minn. R. 7090] 9.16 Permittees must direct discharges from BMPs to vegetated areas unless infeasible. [Minn. R. 7090] 9.17 Permittees must preserve a 50-foot natural buffer or, if a buffer is infeasible on the site, provide redundant (double) perimeter sediment controls when a surface water is located within 50 feet of the project's earth disturbances and stormwater flows to the surface water. Permittees must install perimeter sediment controls at least 5 feet apart unless limited by lack of available space. Natural buffers are not required adjacent to road ditches, judicial ditches, county ditches, stormwater conveyance channels, storm drain inlets, and sediment basins. If preserving the buffer is infeasible, permittees must document the reasons in the SWPPP. Sheet piling and other impermeable barriers installed in a manner that retains all stormwater are considered redundant perimeter control. [Minn. R. 7090] 9.18 Any sediment control made of soil must be temporarily or permanently stabilized within 24 hours. [Minn. R. 7090] 9.19 Permittees must use polymers, flocculants, or other sedimentation treatment chemicals in accordance with accepted engineering practices, dosing specifications and sediment removal design specifications provided by the manufacturer or supplier. The permittees must use conventional erosion and sediment controls prior to chemical addition and must direct treated stormwater to a sediment control system for filtration or settlement of the floc prior to discharge. [Minn. R. 7090] 10.1 Dewatering and Basin Draining. [Minn. R. 7090] 10.2 Permittees must not cause nuisance conditions (see Minn. R. 7050.0210, subp. 2) in surface waters from dewatering and basin draining (e.g., pumped discharges, trench/ditch cuts for drainage) discharges. Permittees must discharge turbid or sediment-laden waters related to dewatering or basin draining to a sediment control (e.g. sediment trap or basin, filter bag) designed to prevent discharges with visual turbidity. To the extent feasible, use well-vegetated (e.g., grassy or wooded), upland areas of the site to infiltrate dewatering water before discharge. Permittees are prohibited from using receiving waters as part of the treatment area. Permittees must visually check and photograph the discharge at the beginning and at least once every 24 hours of operation to ensure adequate treatment has been obtained and nuisance conditions will not result from the discharge. [Minn. R. 7050.0210] 10.3 If nuisance conditions result from the discharge, Permittees must cease dewatering immediately and corrective actions must occur before dewatering is resumed. Nuisance conditions includes, but is not limited to, a sediment plume in the discharge or the discharge appears cloudy, or opaque, or has a visible contrast, or has a visible oil film, or has aquatic habitat degradation that can be identified by an observer. [Minn. R. 7050.0210] 10.4 If permittees must discharge water containing oil or grease, they must use an oil-water separator or suitable filtration device (e.g., cartridge filters, absorbents pads) prior to discharge. [Minn. R. 7090] 10.5 Permittees must discharge all water from dewatering or basin-draining activities in a manner that does not cause erosion or scour in the immediate vicinity of discharge points or inundation of wetlands in the immediate vicinity of discharge points that causes significant adverse impact to the wetland. [Minn. R. 7090] 10.6 If permittees use filters with backwash water, they must haul the backwash water away for disposal, return the backwash water to the beginning of the treatment process, or incorporate the backwash water into the site in a manner that does not cause erosion. [Minn. R. 7090] 11.1 Inspections and Maintenance. [Minn. R. 7090] 11.2 Permittees must ensure a trained person, as identified in item 21.2.b, will inspect the entire construction site at least once every seven (7) days during active construction and within 24 hours after a rainfall event greater than 1/2 inch in 24 hours. [Minn. R. 7090] 11.3 Permittees must inspect and maintain all permanent stormwater treatment BMPs. [Minn. R. 7090] 11.4 Permittees must inspect all erosion prevention and sediment control BMPs and Pollution Prevention Management Measures to ensure integrity and effectiveness. Permittees must repair, replace or supplement all nonfunctional BMPs with functional BMPs by the end of the next business day after discovery unless another time frame is specified in item 11.5 or 11.6.Permittees may take additional time if field conditions prevent access to the area. [Minn. R. 7090] 11.5 During each inspection, permittees must inspect areas adjacent to the project, surface waters, including drainage ditches and conveyance systems but not curb and gutter systems, for evidence of erosion and sediment deposition. Permittees must remove all deltas and sediment deposited in areas adjacent to the project, surface waters, including drainage ways, catch basins, and other drainage systems and restabilize the areas where sediment removal results in exposed soil. Permittees must complete removal and stabilization within seven (7) calendar days of discovery unless precluded by legal, regulatory, or physical access constraints. Permittees must use all reasonable efforts to obtain access. If precluded, removal and stabilization must take place within seven (7) days of obtaining access. Permittees are responsible for contacting all local, regional, state and federal authorities and receiving any applicable permits, prior to conducting any work in surface waters.[Minn. R. 7090] 11.6 Permittees must inspect construction site vehicle exit locations, streets and curb and gutter systems within and adjacent to the project for sedimentation from erosion or tracked sediment from vehicles. Permittees must remove sediment from all paved surfaces within one (1) calendar day of discovery or, if applicable, within a shorter time to avoid a safety hazard to users of public streets. [Minn. R. 7090] 11.7 Permittees must repair, replace or supplement all perimeter control devices when they become nonfunctional or the sediment reaches 1/2 of the height of the device. [Minn. R. 7090] 11.8 Permittees must drain temporary and permanent sedimentation basins and remove the sediment when the depth of sediment collected in the basin reaches 1/2 the storage volume within 72 hours of discovery. [Minn. R. 7090] 11.9 Permittee's must inspect and photograph dewatering discharges at the beginning and at least once every 24 hours during operation. Dewatering discharges that only last for minutes, as opposed to hours, and do not reach a surface water, do not require photographs or documentation. [Minn. R. 7090] 11.10 Permittees must ensure that at least one individual present on the site (or available to the project site in three (3) calendar days) is trained in the job duties described in item 21.2.b. [Minn. R. 7090] 11.11 Permittees may adjust the inspection schedule described in item 11.2 as follows: a.inspections of areas with permanent cover can be reduced to once per month, even if construction activity continues on other portions of the site; or b.where sites have permanent cover on all exposed soil and no construction activity is occurring anywhere on the site, inspections can be reduced to once per month and, after 12 months, may be suspended completely until construction activity resumes. The MPCA may require inspections to resume if conditions warrant; or c.where construction activity has been suspended due to frozen ground conditions, inspections may be suspended. Inspections must resume within 24 hours of runoff occurring, or upon resuming construction, whichever comes first. d.for projects where a pollinator habitat or native prairie type vegetated cover is being established, inspections may be reduced to once per month if the site has temporary vegetation with a density of 70% temporary uniform cover. If after 24 months no significant erosion problems are observed, inspections may be suspended completely until the termination requirements in section 13 have been met. [Minn. R. 7090] 11.12 Permittees must record all inspections and maintenance activities within 24 hours of being conducted and these records must be retained with the SWPPP. These records must include: a.date and time of inspections; and b.name of persons conducting inspections; and c.accurate findings of inspections, including the specific location where corrective actions are needed; and d.corrective actions taken (including dates, times, and party completing maintenance activities); and e.date of all rainfall events greater than 1/2 inches in 24 hours, and the amount of rainfall for each event. Permittees must obtain rainfall amounts by either a properly maintained rain gauge installed on-site, a weather station that is within one (1) mile of your location, or a weather reporting system that provides site specific rainfall data from radar summaries; and f.if permittees observe a discharge during the inspection, they must record and should photograph and describe the location of the discharge (i.e., color, odor, settled or suspended solids, oil sheen, and other obvious indicators of pollutants); and g.any amendments to the SWPPP proposed as a result of the inspection must be documented as required in Section 6 within seven (7) calendar days; and h.all photographs of dewatering activities and documentation of nuisance conditions resulting from dewatering activities as described in section 10. [Minn. R. 7090] 12.1 Pollution Prevention Management Measures. [Minn. R. 7090] 12.2 Permittees must place construction materials and landscape materials under cover (e.g., plastic sheeting or temporary days)or protect them by similarly effective means designed to minimize contact with stormwater. Permittees are not required to cover or protect products which are either not a source of contamination to stormwater or are designed to be exposed to stormwater. [Minn. R. 7090] 12.3 Permittees must place pesticides, fertilizers and treatment chemicals under cover (e.g., plastic sheeting or temporary roofs) or protect them by similarly effective means designed to minimize contact with stormwater. [Minn. R. 7090] 12.4 Permittees must store hazardous materials and toxic waste, (including oil, diesel fuel, gasoline, hydraulic fluids, paint solvents, petroleum-based products, wood preservatives, additives, curing compounds, and acids) in sealed containers to prevent spills, leaks or other discharge.

Vegetative cover must consist of a uniform perennial vegetation with a density of 70 percent of its expected final growth Vegetation is not required where the function of a specific area dictates no vegetation, such as impervious surfaces or the base of a sand filter. [Minn. R. 7090] 13.3 Permittees must clean the permanent stormwater treatment system of any accumulated sediment and must ensure the system meets all applicable requirements in Section 15 through 19 and is operating as designed. [Minn. R. 7090] 13.4 Permittees must remove all sediment from conveyance systems prior to submitting the NOT. [Minn. R. 7090] 13.5 Permittees must remove all temporary synthetic erosion prevention and sediment control BMPs prior to submitting the NOT.Permittees may leave BMPs designed to decompose on-site in place. [Minn. R. 7090] 13.6 For residential construction only, permit coverage terminates on individual lots if the lot is sold to the homeowner, structures are finished, and permanent cover has been established. For lots that are sold to the homeowner where permanent cover has not been established, coverage terminates if temporary erosion prevention and downgradient perimeter control is properly installed and the permittee distributes the MPCA's "Homeowner Fact Sheet" to the homeowner. [Minn. R. 7090] 13.7 For construction projects on agricultural land (e.g., pipelines across cropland), permittees must return the disturbed land to its preconstruction agricultural use prior to submitting the NOT. [Minn. R. 7090] 13.8 When submitting the NOT, Permittees must include either ground or aerial photographs showing the requirements of 13.2 have been met. Permittees are not required to take photographs of every distinct part of the site, however the conditions portrayed must be substantially similar to those areas that are not photographed. Photographs must be clear and in focus and must include the date the photo was taken. [Minn. R. 7090] 14.1 Temporary Sediment Basins. [Minn. R. 7090] 14.2 Where ten (10) or more acres of disturbed soil (5 acres for sites discharging to special or impaired waters, see section 24) drain to a common location, permittees must provide a temporary sediment basin to provide treatment of the runoff before it leaves the construction site or enters surface waters. Permittees may convert a temporary sediment basin to a permanent basin after construction is complete. The temporary basin is no longer required when permanent cover has reduced the acreage of disturbed soil to less than ten (10) acres draining to a common location. [Minn. R. 7090] 14.3 The temporary basin must provide live storage for a calculated volume of runoff from a two (2)-year, 24-hour storm from each acre drained to the basin or 1,800 cubic feet of live storage per acre drained, whichever is greater. [Minn.

[Minn. R. 7090] 14.5 Permittees must design basin outlets to prevent short-circuiting and the discharge of floating debris. [Minn. R. 7090] 14.6 Permittees must design the outlet structure to withdraw water from the surface to minimize the discharge of pollutants. Permittees may temporarily suspend the use of a surface withdrawal mechanism during frozen conditions. The basin must include a stabilized emergency overflow to prevent failure of pond integrity. [Minn. R. 7090] 14.7 Permittees must provide energy dissipation for the basin outlet within 24 hours after connection to a surface water. [Minn. R. 7090] 14.8 Permittees must locate temporary basins outside of surface waters and any buffer zone required in item 23.11.[Minn. R. 7090] 14.9 Permittees must construct the temporary basins prior to disturbing 10 or more acres of soil draining to a common location. [Minn. R. 7090] 14.10 Where a temporary sediment basin meeting the requirements of item 14.3 through 14.9 is infeasible, permittees must install effective sediment controls such as smaller sediment basins and/or sediment traps, silt fences, vegetative buffer strips or any appropriate combination of measures as dictated by individual site conditions. In determining whether installing a sediment basin is infeasible, permittees must consider public safety and may consider factors such as site soils, slope, and available area on-site. Permittees must document this determination of infeasibility in the SWPPP.[Minn. R. 7090] 15.1 Permanent Stormwater Treatment System. [Minn. R. 7090] 15.2 Permittees must design and implement the project so all stormwater discharged from the project during and after construction activities does not cause a violation of state water quality standards, including nuisance conditions, erosion in receiving channels or on downslope properties, or a significant adverse impact to wetlands caused by inundation or decrease of flow. [Minn. R. 7090] NPDES REQUIREMENTS 15.3 Permittees must design and construct a permanent stormwater treatment system to treat the water quality volume if the project's ultimate development replaces vegetation and/or other pervious surfaces creating a net increase of one (1) or more acres of cumulative impervious surface. [Minn. R. 7090] 15.4 Permittees must calculate the water quality volume as one (1) inch times the net increase of impervious surfaces created by the project. [Minn. R. 7090] 15.5 Permittees must first consider volume reduction practices on-site (e.g., infiltration or other) when designing the permanent stormwater treatment system. If this permit prohibits infiltration as described in item 16.14 through item 16.21, permittees may consider a wet sedimentation basin, filtration basin or regional pond. This permit does not consider wet sedimentation basins and filtration systems to be volume reduction practices. [Minn. R. 7090] 15.6 For projects where the full volume reduction requirement cannot be met on-site, (e.g., the site has infiltration prohibitions), permittees must document the reasons in the SWPPP. [Minn. R. 7090] 15.7 Permittees must discharge the water quality volume to a permanent stormwater treatment system prior to discharge to a surface water. For purposes of this item, surface waters do not include man-made drainage systems that convey stormwater to a permanent stormwater treatment system. [Minn. R. 7090] 15.8 Where the proximity to bedrock precludes the installation of any of the permanent stormwater treatment practices required by Sections 15 through 19, permittees must install other treatment such as grassed swales, smaller ponds, or grit chambers, prior to the discharge of stormwater to surface waters. [Minn. R. 7090] 15.9 For linear projects where permittees cannot treat the entire water quality volume within the existing right-of-way, permittees must make a reasonable attempt to obtain additional right-of-way, easement or other permission for stormwater treatment during the project planning process. Documentation of these attempts must be in the SWPPP. Permittees must still consider volume reduction practices first as described in item 15.5. If permittees cannot obtain additional right-of-way, easement or other permission, they must maximize the treatment of the water quality volume prior to discharge to surface waters. [Minn. R. 7090] 16.1 Infiltration Systems. [Minn. R. 7090] 16.2 Infiltration options include, but are not limited to: infiltration basins, infiltration trenches, rainwater gardens, bioretention areas without underdrains, swales with impermeable check dams, and natural depressions.

Permittees must follow the infiltration prohibition in item 16.14 anytime an infiltration system is designed, including those not required by this permit. [Minn. R. 7090] 16.3 Permittees must design infiltration systems such that pre-existing hydrologic conditions of wetlands in the vicinity are not impacted (e.g., inundation or breaching a perched water table supporting a wetland). [Minn. R. 7090] 16.4 Permittees must not excavate infiltration systems to final grade, or within three (3) feet of final grade, until the contributing drainage area has been constructed and fully stabilized unless they provide rigorous erosion prevention and sediment controls (e.g., diversion berms) to keep sediment and runoff completely away from the infiltration area. [Minn. R. 7090] 16.5 When excavating an infiltration system to within three (3) feet of final grade, permittees must stake off and mark the area so heavy construction vehicles or equipment do not compact the soil in the infiltration area. [Minn. R. 7090] 16.6 Permittees must use a pretreatment device such as a vegetated filter strip, forebay, or water quality inlet (e.g., grit chamber) to remove solids, floating materials, and oil and grease from the runoff, to the maximum extent practicable, before the system routes stormwater to the infiltration system. [Minn. R. 7090] 16.7 Permittees must design infiltration systems to provide a water quality volume (calculated as an instantaneous volume) of one (1) inch of runoff, or one (1) inch minus the volume of stormwater treated by another system on the site, from the net increase of impervious surfaces created by the project. [Minn. R. 7090] 16.8 Permittees must design the infiltration system to discharge all stormwater (including stormwater in excess of the water quality volume) routed to the system through the uppermost soil surface or engineered media surface within 48 hours. Permittees must route additional flows that cannot infiltrate within 48 hours to bypass the system through a stabilized discharge point. [Minn. R. 7090] 16.9 Permittees must provide a means to visually verify the infiltration system is discharging through the soil surface or filter media surface within 48 hours or less. [Minn. R. 7090] 16.10 Permittees must provide at least one soil boring, test pit or infiltrometer test in the location of the infiltration practice for determining infiltration rates. [Minn. R. 7090] 16.11 For design purposes, permittees must divide field measured infiltration rates by 2 as a safety factor or permittees can use soil-boring results with the infiltration rate chart in the Minnesota Stormwater Manual to determine design infiltration rates.When soil borings indicate type A soils, permittees should perform field measurements to verify the rate is not above 8.3 inches per hour. This permit prohibits infiltration if the field measured infiltration rate is above 8.3 inches per hour. [Minn. R. 7090] 16.12 Permittees must employ appropriate on-site testing to ensure a minimum of three (3) feet of separation from the seasonally saturated soils (or from bedrock) and the bottom of the proposed infiltration system. [Minn. R. 7090] 16.13 Permittees must design a maintenance access, typically eight (8) feet wide, for the infiltration system. [Minn. R. 7090] 16.14 This permit prohibits permittees from constructing infiltration systems that receive runoff from vehicle fueling and maintenance areas including construction of infiltration systems not required by this permit. [Minn. R. 7090] 16.15 This permit prohibits permittees from constructing infiltration systems where infiltrating stormwater may mobilize high levels of contaminants in soil or groundwater.

R. 7090] 17.2 Filtration options include but are not limited to: sand filters with underdrains, biofiltration areas, swales using underdrains with impermeable check dams and underground sand filters. If permittees utilize a filtration system to meet the permanent stormwater treatment requirements of this permit, they must comply with items 17.3 through 17.11. [Minn. R. 7090] 17.3 Permittees must not install filter media until they construct and fully stabilize the contributing drainage area unless they provide rigorous erosion prevention and sediment controls (e.g., diversion berms) to keep sediment and runoff completely away from the filtration area. [Minn. R. 7090] 17.4 Permittees must design filtration systems to remove at least 80 percent of TSS. [Minn. R. 7090] 17.5 Permittees must use a pretreatment device such as a vegetated filter strip, small sedimentation basin, water quality inlet, forebay or hydrodynamic separator to remove settleable solids, floating materials, and oils and grease from the runoff, to the maximum extent practicable, before runoff enters the filtration system.

Conformance with all comments contained within the Engineer's Memo Dated March 14, 2024. BACKGROUND The Planning Commission is being asked to consider requests by Enclave Companies for a rezoning of the subject parcel described as Lot 1, Block 1, Amber Fields 6th Addition from High Density Residential to Medium Density Residential and for a Major Amendment to the Amber Fields Planned Unit Development in order to construct 178 townhomes. This is a departure from the site plan originally Page 79 of 112 approved for this parcel in Amber Fields, but staff is supportive as the general housing type is similar to the original approval, albeit with fewer units. The rezoning is needed since the proposed townhomes are more traditional in style, whereas the earlier plans were more like many small apartment buildings and were consistent with high density residential development. The proposed PUD amendment also includes a deviation to reduce the required amount of guest parking on site from 89 to 62 spaces (.5 per unit to .34 per unit), a deviation to accommodate a site density of 12.2 units/acre, .2 units/acre higher than allowed in R3, and a deviation increasing the maximum building height from 35' to 38'. Staff is supportive of these deviations, which are described in detail in this report. Site amenities include a clubhouse with a pool, pickle ball court, and a tot lot. A fenced-in dog area will be located in the northern portion of the site along the frontage abutting CSAH 42. Property Owner Earl Street Partners II, LLC Applicant Enclave Companies Location South of County Road 42 and approximately 1,600 feet west of Akron Avenue. Site Area in Acres 14.58 Acres Comprehensive Plan Designation HDR-High Density Residential Current Zoning R4 PUD – High Density Residential Planned Unit Development Proposed Zoning R3 PUD - Medium Density Residential Planned Unit Development Residential Units 178 Units Gross Density 12.2 Units/Acre Net Density 12.2 Units/Acre The Amber Fields Master Development Plan was approved by the City Council at its meeting on September 7, 2021. The overall development plan includes a mix of different housing types ranging from traditional single-family homes to high-density apartment buildings. The proposed townhome community is similar to the Springs community that was originally approved for the site and also similar to Echelon, located further east, in that the units are all located on a single parcel and will be offered for rent rather than for sale. The main inconsistency with the originally approved plan for this site is that the intensity of development is lower, with 178 units versus 268 units. The amenities are similar, and traffic circulation is generally the same with access into the site being provided by two driveways from 148th Street West. Legal Authority Rezonings are legislative decisions by the City, and the approval of Major Planned Unit Development Amendments are also a legislative decisions because of the Code deviations being proposed. Legislative decisions give the Planning Commission more latitude, but consideration should be given to expectations related to the overall Master Development Plan’s intended development pattern for this specific site. General Site Layout The site plan includes twenty-nine residential buildings. Twelve of the buildings will contain 5 or six units in a side-by-side configuration. Seventeen buildings will be configured with 6 or 8 units back-to- Page 80 of 112 back. The side-by-side units will be located around the east, west, and south perimeter of the site. The taller, back-to-back units will be centrally located, including along the northern property boundary abutting CSAH 42. Access to the site is made via two driveways on the south parcel boundary that connect with 148th Street West, a collector road. The western driveway is the main entrance, featuring a landscaped median. The eastern driveway offers secondary access into the site. The clubhouse and other amenities are located immediately north of the main entrance, and somewhat centrally to the site. The buildings are all positioned at least 20' from one another in accordance with Zoning Code standards, and setbacks are consistent with those approved for the Amber Fields Planned Unit Development Master Development Plan. Rezoning The site is currently zoned R4 PUD - High Density Planned Unit Development. Staff advised the applicant during initial conversations that a rezoning to R3-Medium Density would be be needed since the proposed townhomes are not a permitted use in the R4 district. The Rosemount Comprehensive Plan does allow limited R3 zoning within the HDR land use designation. Staff finds that the location of the subject parcel creates a transition between the single family homes to the south and County Road 42, and that the proposed rezoning is consistent with the Comprehensive Plan. The proposed townhomes also create a transition from the High Density Residential land east of the subject parcel. Street and Sidewalk System The street system shown on the site plan provides circulation throughout the development, with entry and egress made through two drives along the southern site boundary. There are secondary, internal streets that provide access to the individual units and connect the perimeter street. The sidewalks are provided on one side of most streets, and pedestrian connections to 148th Street West are included in the layout. A bituminous trail that offers additional pedestrian connections along the northern site boundary is shown on the plan. Parking The zoning ordinance requires 2 enclosed parking spaces per unit plus .5 spaces per unit as guest parking for a total of 445 spaces. Each unit has 2 enclosed parking stalls within their individual garages, as well as two off-street parking spaces on the units' driveways. 62 guest parking spaces are provided on the plan, a ratio of .34 guest parking spaces per unit, The guest parking provided is placed throughout the development, both on street and off. Guest parking is also provided in close proximity to the clubhouse and other amenities. Staff is supportive of the request for a reduction in guest parking stalls as there is still a significant amount of parking provided, and the two driveway stalls are provided in excess of what is required by the code. When compared to the multi-family housing parking requirement of 2 stalls per unit, the proposed plan provides 4.34 stalls per unit overall. Required Provided Enclosed 356 (2 per unit) 356 Guest 89 (.5 per unit) 62 (.34 per unit) Surface/Driveway 0 356 Total 445 774 Parks Page 81 of 112 The Parks and Recreation department reviewed the proposed development. The Parks and Recreation director indicates in his attached memorandum that the parks dedication requirement will be met through developer installed improvements as outlined in the Amber Fields subdivision agreement. Landscaping The zoning code requires one tree per unit for townhome developments and one foundation planting per ten linear feet of building perimeter. Based on a unit count of 178 units, the landscape plan's 172 trees is a shortfall of 6. Staff has included a condition in the recommended action that the applicant update their landscape plan to include a total of 178 overstory trees. Perennials and shrubs are indicated on the plan, and with a total building perimeter, including that of the clubhouse, of 8,810 linear feet, 881 foundation plantings are required. The planting schedule on the applicant's landscape plan shows 2261 perennials and shrubs to be planted on site. These will be located around the dwelling units as well as the clubhouse. The entrance drive features a landscaped median, and additional plantings are shown around the perimeter of the site, including along CSAH 42. Planting Type Required Provided Overstory Trees 178 (1 per unit) 172 (a shortfall of 6) Foundation Plantings 881 (1 per 10 linear feet of building perimeter) 2261 In addition to the overstory trees and foundation plantings, the applicant's landscape plan includes 64 ornamental trees. The Zoning Ordinance specifically calls for a minimum number of overstory trees. Therefore, ornamental trees do not count towards the minimum planting requirement. Utilities Private utilities within the development will connect with the City's sewer and water infrastructure located in 148th Street West. Stormwater will be handled offsite, in the large stormwater basins located centrally within the Amber Fields development. This is consistent with how the rest of Amber Fields has developed. The City's engineer has reviewed the plans and provided comments on the applicant's submittal. The comments are typical of a plan review, but one piece of note is the engineer's comments related to the bituminous trail in the northern portion of the site. The engineer would like further explanation of the benefit of that short trail segment and the memo notes that it transitions from 5’ sidewalks on both ends and does not connect into the larger City trail system. The memo suggests that the developer should consider integrating the trail into the larger City system or maintain it as 5' sidewalk. MAJOR AMENDMENT TO THE AMBER FIELDS PUD There are three deviations from the code needed to facilitate the proposed plan, and none are a vast departure from the requirements of the code. The widest deviation is from the guest parking requirement of .5 stalls per unit. The proposed development provides 4 stalls allocated to each unit and another 62 for guests to the complex. The second deviation requested is to allow for a density of 12.2 units per acre, .2 units per acre above the maximum density. The last deviation would increase the maximum building height by 3 feet from 35' to 38'. The buildings that reach that height are the back-to-back units which are either located centrally or along the property boundary abutting CSAH 42. There would be no discernible impact on properties outside the subject property. Page 82 of 112 Generally, staff finds the development to be consistent with what was anticipated and already approved for the site. Moreover, the height and density deviations would not be necessary but for the rezoning to accommodate the townhouse-style units. Lastly, consideration may be given to the fact that the units will be for rent rather than for sale, and the site will be managed similarly to an apartment building. RECOMMENDATION Staff recommends approval of the requests based on the information provided by the applicant and reviewed in this report. Staff recommends several conditions of approval, which are listed in the Recommended Action above.

Applicant should provide responses to each comment and redline comment. We offer the following comments below. Civil Comments: 1. General a. Show removals on Existing Conditions Plan Sheets b. Retaining walls exceeding 4’ in height shall require a plan prepared by a licensed engineer submitted for review and approval by the Building Official prior to permit issuance. Noted. 2. Utilities a. Provide rim and inverts for all sanitary sewer structures. Rim and invert elevations are included in the schedule on Sheet C -4.2. b. At the two connection points, use the existing gate valve or replace back to including the existing gate valve. The existing gate valve will be used at the connection points. c. Coordinate with City Public Works whether hydrants should be located on the same side of the street as the watermain or should the fronts of units be avoided . Water main routing has been revised. All but one hydrant are on the same side of the street as the main. This area is crowded with storm sewer and other services and provides good coverage of the area in its proposed location near Building 21. Page 100 of 112 Townhomes at Amber Fields – Preliminary Plat Review March 14, 2024 Page 2 d. Gate valves and storm sewer castings near the curb line will make it difficult to compact and maintain bituminous between the castings and the curb line. Water main and storm sewer has been revised to avoid this. e. The proposed watermain is within 10' of the existing sanitary sewer mains in the northeast area of the development. i. Coordinate with MDH to achieve an acceptable running alignment. Water main has been revised to provide more than 10’ of separation. f. Show proposed adjustments to existing structures that are impacted by development grading. i. Based on the size of adjustments, additional sections may need to be added or removed ii. Coordinate approval and construction of adjustments with the City and MCES as applicable. A note has been added to the grading plan. Construction of adjustments will be coordinated with MCES and more detail will be included based on that. g. Several sanitary sewer structures have two outlets i. Verify this is acceptable with City Public Works This has been reduced to one structure. One of the outlets is one foot above the structure invert and will not receive flow, but is connected for maintenance access. h. Provide profiles for all utilities. i. Show utility crossings in all profiles. ii. Maintain minimum 18” separation between utilities. iii. Insulate when storm sewer is within 36” of watermain. Profiling and separations are in process. i. Verify catch basins are not located near ped ramps or driveways to impact curb transitions. Curb on the driveway side will be mountable throughout to avoid many transitions, as will as inlet castings. Separation has been provided between pedestrian ramps and catch basins. 3. Streets, Signage and Street Lighting a. Provide turning movements for fire/emergency, garbage, and delivery vehicles. This is provided. b. Review impact of on street parking areas on sight lines for drivers turning from adjacent streets Noted. c. Provide the benefit of the proposed trail on the north end of the development. i. It transitions from 5’ sidewalks on both ends and does not connect into the larger City trail system. ii. Consider integrating the trail into the larger City system or maintain as 5' sidewalk. The trail has been removed. d. Discuss the proposed locations of crosswalks as well as stops signs relative to the clubhouse and throughout the development to be consistent. Page 101 of 112 Townhomes at Amber Fields – Preliminary Plat Review March 14, 2024 Page 3 The stop signs are provided for the 4-way intersection near the clubhouse and entrance of the development. e. There is a significant number of existing sanitary sewer mains on the north end of the project. i. Provide an agreement for the process of how disruption will be handled at the northeast corner of the site when future maintenance or construction of these sewer mains needs to occur. After coordination with MCES, an agreement will be obtained and provided. 4. Landscape a. No comments Grading, Drainage, and Erosion Control Comments: 5. General a. The site layout included in these plans shows a different configuration than what was included in the original PUD. If this change in layout results in additional impervious, the applicant should submit an updated SWMP and updated HydroCAD modeling representative of this new layout and additional impervious to confirm the site is still meeting stormwater requirements. The site will not create impervious surface exceeding what was included in the original PUD. The SWMP assumed 97% post-development impervious cover for the parcel and this layout proposes 64% impervious cover. 6. Ponds and Wetlands a. Include NWL/HWL for Basin 1918 to the west of the site to the grading plan. This has been added. b. Confirm the retaining wall will not modify the storage within Basin 1918 below the HWL. If the storage below the HWL is modified, update and resubmit the HydroCAD modeling for Amber Fields. The retaining wall will not modify the storage within the basin below the HWL. 7. Emergency Overflow Routes a. Note EOFs for all localized low points both in the roadway and in the side/rear yards. This has been provided on the grading plan. 8. Retaining Walls a. Add TW/BW elevations for the retaining wall northeast edge. This has been added. 9. Erosion Control a. No comments. 10. Grading Page 102 of 112 Townhomes at Amber Fields – Preliminary Plat Review March 14, 2024 Page 4 a. Clarify use of three sets of contours on this grading plan (grey dashed, black thin continuous and black bold continuous) in the legend. The grading plan has been revised to p b. Grading is shown in the CSAH 42 ditch north of the lot line, confirm this is correct. If so, is this grading planned just to remove an existing access roadway? Grading has been revised to maintain the access. c. Update the proposed contour tie ins on the east side of the site. The tie ins have been revised. d. Show high points and drainage between all buildings. This has been added. e. Provide driveway elevations at both ends of all buildings as well as any grading breaks (low or high points) along the building. These have been provided. Stormwater Management Plan: 1. General Storm Sewer Design a. As part of final design, provide rational method storm sewer sizing calculation and catch basin drainage area map (including the area intended to drain to the proposed stubs) along with storm sewer sizing calculations to confirm storm sewer is sized for a 10-year storm event. A drainage map and storm sewer sizing calculations have been provided electronically. b. Include sumps on CBMH 20 and CBMH 2 prior to the connection to the existing stub. Sumps have been included on these two structures. c. Adjust storm sewer where noted on the plans to be at least 10 feet away from the building edge. There are still a couple locations where storm sewer is within 10 feet of the building, however the material is called out to be PVC SCH 40 due to MDLI requirements crossing water services in these locations. Please advise if this is still not acceptable. d. Include storm sewer castings for proposed storm structures. Castings have been included in the schedule on Sheet C-4.2. e. Confirm all proposed storm sewer shown on the plans will be privately owned and maintained. If any storm sewer is proposed to be publicly owned and maintained, RCP will be required for those pipes.

ATTACHMENTS: Consultant's Memo, Current vs Proposed Zoning Map, District Conversion Tables APPROVED BY: AK RECOMMENDED ACTION: Hold a public hearing and make a Motion to recommend the City Council adopt the proposed zoning map. BACKGROUND Community Development staff along with the consultant team from HKGi will present a summary of changes to the City's zoning map in alignment with the work completed of the past year and a half. Please see the attached memo from HKGi outlining the scope of the project. The proposed map reflects the consolidation of certain districts and the elimination of unused or little-used districts. Staff has created a webpage for the code update and encourages the Planning Commission and public to view the documents there: https://www.rosemountmn.gov/899/2024-Zoning-Code-Update Additional materials and newsletter articles have been distributed since the Planning Commission reviewed the new zoning code text. The City Council will also be holding a public hearing during its meeting on June 4 to receive comment ahead of taking action on the repeal and replacement of the existing code with the Code Update and map. Initially staff had anticipated the Council would adopt the zoning and subdivision ordinance text update separately from the zoning map. Following discussion with the City's attorney, staff is bringing both the map and the text update to the Council together for two reasons. First, the zoning map is considered part of the zoning code and requires the same approval process as the text update. Second, the publication and effective date of the text and map need to be the same. RECOMMENDATION Hold a public hearing, discuss the proposed changes to the City's zoning map, and recommend CIty Council adopt the zoning map at its meeting on June 4. Page 106 of 112 800 Washington Avenue North, Suite 103 Minneapolis, MN 55401 Planning Commission Meeting Memo To:Rosemount City Council and Planning Commission From:Jeff Miller and Beth Richmond, HKGi Date:May 28, 2024 Subject:Zoning Map Amendments Public Hearing Overview At the May 28th Planning Commission meeting, planning consultants (HKGi) and city staff will present an overview of the proposed zoning map amendments. As required by State law and the City’s Zoning Code for any code and map amendments, a public hearing will also be held by the Planning Commission at the May 28th meeting. Following the public hearing and the Planning Commission’s discussion of the amended zoning map, the Planning Commission will consider recommendation of the amended zoning map to the City Council for adoption. The proposed amended zoning map is available for public review on the City’s website. The Zoning Map and Zoning/Subdivision Code amendments are expected to be considered for adoption by the City Council at the June 4th meeting. A public hearing for the Zoning/Subdivision Code amendments was held at the Planning Commission meeting on March 18th. The Planning Commission recommended adoption of the Zoning/Subdivision Code amendments at that meeting. Purpose of the Zoning Map Amendments As part of the Zoning/Subdivision Code Update project, the City’s zoning districts are proposed to be consolidated from 21 today to 14 proposed districts. A new mixed-use district (MX-2) has also been created for the Hwy 42 mixed use nodes. The purpose of the zoning map amendments is to consolidate districts that have similar standards, create more flexible and simplified districts, and eliminate districts that are not used or needed. The City is also required to ensure consistency between the Zoning/Subdivision Code and the 2040 Comprehensive Plan. The City Council adopted the 2040 Comprehensive Plan Update in March 2020. This project is not making any changes to the 2040 Comprehensive Plan and the 2040 Future Land Use Map remains in place. The intent of this update is to address the aspects of the Zoning/Subdivision Code that are in conflict with the 2040 Comprehensive Plan or have not been updated to address the City’s current development market trends/changes. The project’s intent is also to create zoning and subdivision regulations that are modern, consistent, and user-friendly.
