Public Hearing: Lino Lakes Main Street Master Plan Leila Bunge with Kimley Horn presented the Main Street Master Plan presentation. On July 8, 2024, the City Council adopted Ordinance No. 11-24 establishing a moratorium on residential development around the Main Street corridor between Sunset and 4th Avenue. The purpose of the moratorium is to allow for the completion of a master plan and AlternativeUrban Areawide Review (AUAR) for the area. The moratorium will end on August 15, 2025. The AUAR comment period ended on June 26th and responses to comments have been prepared by the project team. The adoption of the AUAR was brought to the City Council for consideration on August 11, 2025. An AUAR mitigation plan has been incorporated into the Master Plan document to guide development activities. The first draft Master Plan was presented to the Planning & Zoning Board on July 9, 2025. The Master Plan is a compilation of the process undertaken, site overview and constraints and planning considerations. The Preferred Scenario – Scenario 2 concept is more fully developed with key concepts highlighted and system plans. Mr. Wipperfurth had questions about the next steps once the Master Plan is adopted. Mr. Grochala let the Board know that the City would need to makea Comprehensive Plan Amendment, which would amend the current 2040 Plan. Mr. Wipperfurth asked whether developers would be able to apply to develop the land before the comprehensive plan is adopted. Mr. Grochala explained that theoretically someone could submit an application but they would have to follow the upcoming adoption. Mr. Vojtech had questions about the addition of wells to the area. Mr. Grochala explained that two wells need to be added over the next thirty years. The wells would be added as needed when future development starts. Mr. Root opened the public hearing at 6:57 p.m. DRAFT MINUTES Planning & Zoning Board August 13, 2025 Page 3 Angela Coil, 7672 Sunset Avenue, asked for a better understanding of Sunset Avenue becoming a gateway since there is some confusion with the county. Ms. Coilhad concerns regarding the potential increase in trafficin the area. Ms. Coil likes the small town feel of Lino Lakes and does not think the City needs to develop as quicklyand believes residents are opposed to high density housing. Sue Bass, 197 Shetland Lane, had concerns regarding the proposed connection of Century Trail to Main Street. Ms. Bass was worried that Robinson Drive would experience vehicles travelling faster through the area to avoid potential traffic. Ms. Bass had concerns about the safety of families in the neighborhood if more traffic were to travel through. Julia Nelson, 689 Oak Lane, was glad the topic of water consumption in the area was brought up. Ms. Nelson had concerns about the City being sued for overuse of water. Ms. Nelson does not think it would be as simple as adding more wells to provide water for potential future developments. Ms. Nelson understands that the City must follow guidelines put in place by the Metropolitan Council, but believes Lino Lakes should take a stand. Sam Bennett, 6841 Lakeview Drive, wanted to speak on prioritizing parks being closer to commercial space. Mr. Bennett believes having the park away from the commercial space in the proposed plan would not promote community development. Chris Stowe, 426 Pine Street, agreed with the previous comment regarding water and wells concerns. Mr. Stowe brought up concerns regarding speed limits and safety on Pine Street with potential new developments. Mr. Stowe is not in favor of higher density housing. Mr. Vojtech moved to close the public hearing. Motion seconded by Mr. Kohler. The public hearing was closed at 7:09 p.m. Mr. Root addressed comments made during the public hearing. Mr. Root asked staff to clarify Sunset Avenue becoming a gateway. Mr. Grochala stated that the gateway would be more aesthetic not becoming a highway. Sunset Avenue is a county road and the county is currently designing. Mr. Grochala explained that Main Street would be where the majority of traffic would be routed. Mr. Root wanted to address the comments regarding density requirements. Mr. Grochala stated that comments and resident concerns regarding density have been frequent for thirty years. The City is growing in the path of development for the metro area and the City is required to meet density requirements per Metropolitan Council DRAFT MINUTES Planning & Zoning Board August 13, 2025 Page 4 and state legislature. The City is trying their best to address those concerns with the residents. Mr. Root wanted to address pushing back on the Metropolitan Council. Mr. Grochala spoke about a previous lawsuit with Lake Elmo and the risks to pushing back on the Metropolitan Council. Mr. Root wanted to address the concerns about traffic. Mr. Grochala stated that there was a very extensive traffic study performed in the AUAR. The growth of all the cities around us is also a factor in how the City will move forward with developing the roads. Mr. Grochala stated the City must match what is going on with the county updates to the roads. Mr. Grochala stated that in the current 2040 Comprehensive Plan, Robinson Drive is a collector street. Mr. Root wanted to address the wells and drinking water. Mr. Grochala stated the City has a long-range plan for water use. The Metropolitan Council is observing our water use to get a better understanding of trends for future development in the metro area. Mr. Grochala explained that currently the biggest concern is trying to eliminate water use for irrigation. Mr. Root wanted to address that development would not be allowed if there was no water supply. Mr. Grochala confirmed. Mr. Root wanted to address the flooding. Mr. Grochala stated that the Northwest area is low elevation and are in floodplains. The Board is aware that the Citydoes extensive flood studies. Mr. Grochala stated that developers will have to prove that they will be able to accommodate the flooding in the area. Mr. Root wanted to address the parks in this plan. Mr. Grochala spoke about the City’s plan to have few larger parks with more enhancements. Mr. Grochala stated that this plan is a guideline and that a potential development could come in and place a park closer to commercial areas. Mr. Root wanted to address the comments about Madinah Lakes and potential new development applications being able to come in with the moratorium being lifted August 15, 2025. Mr. Grochala explained that if the developers were to come in they would be going through the land use application process along with the comprehensive plan amendment. Ms. Guthmueller had a question about Metropolitan Council and the requirements for density. Ms. Guthmueller understoodthat there would be lawsuits if the City were to not follow their adopted guidelines but wants better understanding of theMetropolitan DRAFT MINUTES Planning & Zoning Board August 13, 2025 Page 5 Councils purpose. Mr. Grochala explained the purpose of the MetropolitanCouncil. Any updates the City makes to our comprehensive plan would have to go before the Metropolitan Council to ensure we are aligned with the regional plans. The Metropolitan Council plays a role in helping the community with access to sanitary sewer and water. The City mustprovide a share of the region’s affordable housing. The City must make accommodations for affordable housing along with the surrounding cities. The MetropolitanCouncil requires the Cityto have a certain amount of land that is guided to affordable housing. Ms. Guthmueller wonders if we are building out too quickly and if there is a need for this much housing in the area. Ms. Guthmueller also had questions regarding surrounding cities and if we are all followed by the same rules. Mr. Grochala explained that the Metropolitan Council does have different standards depending on the City and does factor individual cities. Mr. Grochala explained that Lino Lakes forecasted population growth has been consistently slow compared to that of Blaine and Hugo. Ms. Guthmueller wanted to know if Metropolitan Council had to approve the Master Plan. Mr. Grochala explained that the Metropolitan Council would approve the amendment to the Comprehensive Plan but not the Master Plan itself. Ms. Hankee pointed out that Lino Lakes did push back on density with Metropolitan Council previously. Mr. Evenson moved to approve the Main Street Master Plan. Motion seconded by Mr. Laden. Motion carried 7-0. B. Continued Public Hearing: Peltier Ponds Comprehensive Plan Amendment, Rezoning, PUD Preliminary Plan and Preliminary Plat Ms. Larsen presented the staff report.

Ms. Larsen explained we have the ability to extend the process up to 120 days total. Will Rogers, 7608 Peltier Lake Drive, wanted to speak about issues he mentioned at the public hearing held in July. Mr. Rogers is in favor of City water being provided to the area.Mr. Rogers had concerns that more people would access his property. Mr. Rogers was not in favor of a road connection for public safety purposes and does not believe it would be necessary. Mr. Root addressed the extension to the existing road.

Attn: Thomas Budzynski 9100 Baltimore St NE Blaine, MN 55449 OWNER: CB Property, LLC Attn: John Commers 11841 Flanders Circle NE Blaine, MN 55449 INTRODUCTION The applicant, TJB Homes, Inc, submitted a land use application to amend the preliminary plat application for Lake Amelia Woods. The applicant proposes to revise the grading plan related to the existing four (4) lot rural subdivision. Since the grading plan is part of the preliminary plat application, any significant change to the grading plan requires a formal preliminary plat amendment. No additional lots are being created. Tentative Review Schedule: Complete Application Date:August 12, 2025 60-Day Deadline:October 11, 2025 Environmental Board Meeting:N/A Park Board Meeting:N/A Planning & Zoning Board Meeting:September 10, 2025 City Council Work Session:October 6, 2025 City Council Meeting:October 13, 2025 1 This staff report is based on the following information: Preliminary Plans for Lake Amelia Woods prepared by Civil Methods, Inc. dated August 7, 2025 nd Certificate of Survey and Preliminary Plat for Lake Amelia Wood 2 Addition prepared by Acre Land Surveying dated August 7, 2025 BACKGROUND Original Preliminary Plat and Final Plat On November 8, 2021, the City Council passed Resolution No. 21-114 approving the preliminary plat for Lake Amelia Woods. The preliminary plat is a four (4) lot, 10 acre rural subdivision east of Amelia Lake. On June 27, 2022, the City Council passed Resolution No. 22-18 approving the final plat for those four (4) lots. ANALYSIS Zoning The lots are zoned R-X, Rural Executive. One single family detached dwelling is allowed per 10 acre parcel. Current Zoning R-X, Rural Executive Current Land Use Vacant Rural Residential 2040 Land Use Plan Urban Reserve Utility Staging Area Post 2040 Subdivision Ordinance Conformity with the Comprehensive Plan and Zoning Code The amended preliminary plat application is consistent with the comprehensive plan for urban reserve development and zoning code requirements for R-X, Rural Executive. Blocks and Lots The original and amended preliminary plat contain four, 10 acre lots. There are no changes to the lot lines, lot sizes, or number of lots. 2 Storm Water Management and Erosion and Sediment Control Per City Code Section 1001.041, part of the preliminary plat application is the preliminary, grading, drainage and erosion control plan. This grading plan is reviewed and approved as part of the preliminary plat process. Any significant change to the approved grading plan requires a preliminary plat amendment. In 2021, City Code Chapter 1011, Stormwater, Erosion and Sediment Control required each lot to have it’s own stormwater pond for stormwater management. The original preliminary plat and grading plans complied with this City code. In 2023, City Code Chapter 1011 was amended to exempt single-family residential subdivisions less than seven (7) lots from stormwater management requirements. City Code Section 1011.011(2) Exceptions: (d) Stormwater Management Requirements do not apply to single-family residential subdivisions creating seven or fewer lots that: 1. Establish no new public roadway; and 2. Includes no private roadway/driveway serving three or more lots. Now, each individual lot is not required to have a stormwater pond. This results in less tree removal and no future stormwater pond maintenance. The applicant has submitted revised grading plan compliant with current code. Easement Vacation As required, drainage and utility easements were dedicated on the Lake Amelia Woods final plat over the stormwater ponds. These easements will be vacated since the stormwater ponds are not required. The City Council will hold a public hearing on the nd vacation. New easements will be dedicated on the Lake Amelia Woods 2 Addition final plat. Public Land Dedication No new lots are being created; therefore, no additional public land dedication or fees are required. Wetlands/Floodplain/Shoreland Management A 75 ft wide vegetated wetland/shoreline buffer declaration along Wetland A (lake) was recorded with the original Lake Amelia Woods final plat as a stormwater management best management practice (BMP) to minimize runoff pollutants from entering the lake. The buffer will also help stabilize the shoreline, reduce erosion and support aquatic 3 plants and wildlife. One (1) access opening through the wetland buffer to the lake no greater than twenty (20) ft wide is allowed per lot. No structures, not even water- orientated accessory structures, are allowed in the 75 ft wide wetland/shoreline buffer zone. This buffer will remain in place and will not change with the proposed revised grading plan. Current Single Family House Construction A single family house is currently being constructed on Lot 3, Block 1, Lake Amelia th Woods (6175 20 Avenue) by the applicant as a spec home. A certificate of occupancy will not be issued until the final plat has been approved by City Council and recorded and any required plan or permit revisions have been made. Additional Government Agency Review Comments Anoka County Highway Department provided comments in the attached letter dated August 25, 2025. Agreements Stormwater Maintenance Agreement A stormwater maintenance agreement is not required since a stormwater management plan is not required per City Code Chapter 1010. Final Plat and Development Agreement The applicant shall submit a Land Use Application for final plat after preliminary plat approval. A Development Agreement may be required by the City as part of the final plat application. Findings of Fact Per Section 1001.013, Premature Subdivision: (1) General. Any concept plan, preliminary plat or final plat deemed premature pursuant to the following criteria shall be denied by the City Council. (2) Conditions for establishing a premature subdivision. A subdivision may be deemed premature should any of the following conditions not be met. (a) Consistency with the Comprehensive Plan. Including any of the following: 1. Land use plan; 4 2. Transportation plan; 3. Utility (sewer and water) plans; 4. Local water management plan; 5. Capital improvement plan; and 6. Growth management policies, including MUSA allocation criteria. The amended Lake Amelia Woods preliminary plat application is consistent with the comprehensive plan. (b) Consistency with infill policies. A proposed urban subdivision shall meet the city's infill policies: 1. The urban subdivision must be located within the Metropolitan Urban Service Area (MUSA) or the staged growth area as established by the city's Comprehensive Plan; 2. The cost of utilities and street extensions must be covered by one or more of the following: a. An immediate assessment to the proposed subdivision; b. One hundred percent of the street and utility costs are privately financed by the developer; c. The cost of regional and/or oversized trunk utility lines can be financed with available city trunk funds; and d. The cost and timing of the expenditure of city funds are consistent with the city's capital improvement plan. 3. The cost, operation and maintenance of the utility system are consistent with the normal costs as projected by the water and sewer rate study; and 4. The developer payments will offset additional costs of utility installation or future operation and maintenance. The amended Lake Amelia Woods preliminary plat application remains a 4 lot rural subdivision with private wells and septic systems. Per the 2040 Comprehensive Plan, the subject site is guided urban reserve and the land is preserved for post-2040 development. Land use prior to 2040 is limited to agricultural related uses and single family residential limited to 1 unit per 10 acres. The proposed development of 1 unit per 10 acres is consistent with the comprehensive plan’s infill policies. (c) Roads or highways to serve the subdivision. A proposed subdivision shall meet the following requirements for level of service (LOS), as defined by the Highway Capacity Manual: 1. If the existing level of service (LOS) outside of the proposed subdivision is A or B, traffic generated by a proposed subdivision will not degrade the level of service more than one grade; 2. If the existing LOS outside of the proposed subdivision is C, traffic generated by a proposed subdivision will not degrade the level of service below C; 3. If the existing LOS outside of the proposed subdivision is D, traffic generated by a proposed subdivision will not degrade the level of service below D; 5 4. The existing LOS must be D or better for all streets and intersections providing access to the subdivision. If the existing level of service is E or F, the subdivision developer must provide, as part of the proposed project, improvements needed to ensure a level of service D or better; 5.

However, the city may, at its discretion, consider developer-financed improvements to correct any street deficiencies; 7. The LOS requirements in divisions (2)(c)1. to 4. above do not apply to the I- 35W/Lake Drive or I-35E/Main St. interchanges. At city discretion, interchange impacts must be evaluated in conjunction with Anoka County and the Minnesota Department of Transportation, and a plan must be prepared to determine improvements needed to resolve deficiencies. This plan must determine traffic generated by the subdivision project, how this traffic contributes to the total traffic, and the time frame of the improvements. The plan also must examine financing options, including project contribution and cost sharing among other jurisdictions and other properties that contribute to traffic at the interchange; and 8. The city does not relinquish any rights of local determination. The amended Lake Amelia Woods preliminary plat application meets the requirements th for level of service (LOS). All 4 lots are served by CSAH 54/20 Avenue which is an A- Minor Reliever. The road has capacity for 4 additional lots. The city does not relinquish any rights of local determination.

Engineering •General The Lake Amelia Woods preliminary plat proposes to create four 10-acre parcels for single thth family homes along 20 Avenue (CSAH 54) in place of two existing parcels: 6149 20 Ave and the parcel immediately to the north (PID 35-31-22-13-0004). All of the proposed parcels Ms. Katie Larsen 9/3/2025 Page 2 th will be accessed from 20 Avenue (CSAH 54) and abut Amelia Lake. The lots are within the Shoreland Overlay District of Amelia Lake. The existing lots have a total area of 1,779,327 square feet (40.85 acres). Each of the new lots is proposed to be over 10 acres in area and include the building pads for future homes. Comments: 1.Plans shall reference the current version of the City Standard Specifications found on the City website and all details shall be updated to City Standard Details as applicable. Reference to the City Standard Specifications has been added, and the City Standard Details have been included. Please update GEN-13 and GEN-22 to the most recent version (found in Appendix C of the Standard Specifications). The indicated details have been updated to the most recent versions. 2.Per the Shoreland Ordinance there shall not be any facilities or construction within the 150’ shoreland impact zone. Stormwater biofiltration basins have been moved to be outside the 150’ shoreland impact zone. The same treatment volume and configuration has been maintained to ensure equivalent hydrologic function. The conceptual house footprints and drives are also located outside of the 150’ shoreland impact zone. 3.Applicant shall provide a permit or written authorization from Great River Energy and UPA to work within their easements. Permission will be obtained as needed from Great River Energy and UPA prior to completion of final construction plans. Prior to approving the final plat, the City of Lino Lakes will require written authorization from Great River Energy and UPA. See document for release of easement. City Attorney is reviewing document. OK 4.Additional geotech data required: a.The applicant is proposing homes in old borrow pit areas. Building pad locations shall be evaluated for bearing capacity and per building code. Notes will be added to final construction plans indicating the requirement for additional geotechnical investigation. Final construction plans will include any corrective measures resulting from the investigation. b.Percolation tests shall be provided for filtration basins. The filtration basins are planned to be constructed with specified granular borrow material, with predictable percolation rates, to ensure proper function. They will also include underdrains to ensure proper drawdown. •Grading & Stormwater Management The Lake Amelia Woods Plat will require site grading for the proposed house pads, the proposed driveways, storm water facilities, and other site grading. Elevations for the proposed house pads were provided on the grading plan for each property. The minimum Lake Amelia Woods Final Plat Engineering Review Ms. Katie Larsen 9/3/2025 Page 3 elevations for the house pads are dependent on the groundwater elevation, the ordinary high water level (OWHL) of the Amelia Lake, and the design of the stormwater facilities. The existing parcels are within the Amelia Resource Management Unit. The applicant is proposing approximately 2.22 acres of new impervious surface for the proposed driveways and proposed house pads at this time. The proposed project is within the Vadnais Lake Area Water Management Organization (VLAWMO). Stormwater BMPs are needed to meet City stormwater and shoreland requirements. The applicant is proposing to meet City stormwater requirements by constructing several stormwater basins and infiltration basins. The design of the ponds shall meet the requirements of Table 6 of the City’s Stormwater Management ordinance. Comments: 1. The building pad Low Floor Elevations (LFE’s) must be 4 feet above the highest known groundwater level. The highest known groundwater level was estimated at elevation 910.5, corresponding to the mottles in SB3. The minimum LFE would therefore be 914.5. All LFEs are now above this elevation. 2.The LFE elevation of future homes shall not be lower than the HWL elevations of the adjacent storm basins. House pad elevations and pond elevations were adjusted so that all pond HWLs are lower than the adjacent future home LFEs. The proposed EOF and HWL levels for the basins on Lots 1 & 2 are at or just below the LFE. City staff meet and reviewed the EOF for the basins and the proposed lot grading. The pond runoff in high water conditions overflows directly to the lake and wetland. Staff recommends allowing the proposed basins to be constructed as currently shown in order to minimize impacts to natural features and use the existing topography. Per staff recommendation the basins were kept as shown. 3.For future maintenance purposes, the basins shall be located on the property for which they are treating impervious surface. Stormwater biofiltration basins have been relocated so that they are on the property for which they are treating impervious surface. 4.Filtration basins shall be located outside of the high vulnerability area shown in the Drinking Water Supply Management Area, see attached map. Please incorporate liners for the basins within the high vulnerability area. The high vulnerability area covers a significant portion of the project area, and it would not be possible to provide adequate stormwater treatment on each individual property outside of the high vulnerability area. It may also be noted that the proposed basins are biofiltration basins with an underdrain, and not infiltration basins. The likelihood of any contamination occurring because of these biofiltration basins is minimal to nonexistent. However, if still considered necessary, for the basins on proposed lots 1 and 2 (within the high vulnerability area) final plans will include a liner to be installed underneath the basin to prevent any stray infiltration. Applicant to include a clay liner for the basins on proposed lots 1 and 2. The basin detail has been modified to include the required clay liner for the basins on proposed lots 1 and 2. 5.Applicant to show the location of turf maintenance access to basins. Applicant to confirm access is traversable. Lake Amelia Woods Final Plat Engineering Review Ms. Katie Larsen 9/3/2025 Page 4 Turf maintenance access shown on revised plans. Turf maintenance access should not be located within the septic areas (see Lot 4). The turf maintenance access location has been adjusted to be out of the septic area. Access is not a problem in this location, but in any case, access paths from the driveway have been noted on the sides of the basin. 6.Plans shall show rip rap or alternative stabilization for drain tile underdrain outlets. Riprap splash pad is indicated on plans for underdrain outlets. Detail will be included on final plans. 7.Provide calculations to confirm the adequacy of the sizing for the proposed culverts. The culvert shown on sheet C02 velocity exceeds 6 fps. Design outlets to the wetlands to achieve an outlet velocity less than 6 fps. The proposed culverts, including the noted culvert on sheet C02, have been modified to reduce velocity to less than 6 fps for the 100-year storm flow. HydroCAD results for proposed culverts are provided in the following table: Sheet #Culvert LocationPeak Flow Velocity C01Outlet from Basin B1P5.8 FPS C02Under Lot 2 Driveway4.4 FPS C02Outlet from Basin B2P4.6 FPS C03Outlet from Basin B5P5.9 FPS C04Outlet from Basin B8P3.9 FPS 8.Address all redline comments shown on plans 9.Grading or construction in the utility easement will require the authorization of the facility owner a.Verify all clearances are met and poles are not undermined with construction b.Show all utilities and poles on plans 10.Label all EOFs 11.Show all proposed wetland buffer signs on plans (see preliminary plat) 12.One of the 918 Contour lines that extends across several pages is the wrong line type 13.Adjust Lot 4 Plan Sheet to include the full extents of Lot 4 14.Show how water in the low area along the roadside of Lot 4 gets to the wetland to the west a.Provide a proposed culvert with invert elevations Lake Amelia Woods Final Plat Engineering Review Ms. Katie Larsen 9/3/2025 Page 5 •Water Supply The existing properties are identified as part of the Stage 3 Planned Service Area in the th 2040 Comprehensive Plan. There is not currently any existing water main along 20 Avenue (CSAH 54) in this area. The 2040 Comprehensive Plan does identify a future 8” watermain loop in this area. The proposed homes will need to install wells. Comments: 1.Proposed well locations shall be shown on the preliminary plans. Applicant to provide dimensions from proposed well locations to proposed building pads and to proposed septic systems (primary and secondary). Well locations have been updated and shown on the Preliminary Plat. Applicant to also put proposed well locations on the grading plans. Well locations have been added to the grading plan sheets. Well locations will be further reviewed with building permit applications. Well locations should not be within proposed driveways. Well location on Lot 3 conflicts with the drain tile. Well locations are not within driveways. Lot 3 yard drain location adjusted to accommodate the well location. The properties with private wells within the high vulnerability zone of the DWSMA will be required to connect to municipal water if municipal water becomes available in the future (per City Code). Noted. •Sanitary Sewer The existing properties are identified as part of the Stage 3 post 2040 Planned Service Area in the 2040 Comprehensive Plan and are located in the 4C sub-district. There is not th currently any existing sanitary sewer along 20 Avenue (CSAH 54) in this area. The proposed homes will be served by private septic systems. •Transportation th The site is located between Amelia Lake and 20 Avenue (CSAH 54). All proposed th properties will have access off of 20 Avenue (CSAH 54), an Anoka County state aid highway and an A-Minor Arterial Reliever. A right-of-way width 120-ft is required for minor th arterial streets. The existing right-of-way along 20 Avenue (CSAH 54) varies from 55 feet to th 70 feet west of centerline. For a portion of the plat, 20 Avenue (CSAH 54) is within the th larger Interstate 35E right-of-way. 20 Avenue (CSAH 54) has capacity to handle the additional traffic from the new lots. Anoka County Parks Regional Trail and the City of Lino Lakes Comprehensive plan identify th a future reginal trail along the west side of 20 Avenue (CSAH 54). Comments: th 1.An additional 5 feet of right-of-way adjacent to 20 Avenue (CSAH 54) where there is less than 60 feet will be required for future reconstruction purposes (60 feet total right-of-way width west of CSAH 54 centerline) 60 FT from centerline of CSAH 54 to proposed ROW shown. Lake Amelia Woods Final Plat Engineering Review Ms. Katie Larsen 9/3/2025 Page 6 •Wetlands and Mitigation Plan There are multiple existing wetlands within the Lake Amelia Woods project area. The plans note that the wetland information was provided by Midwest Natural Resources, Inc. and that field work was done between June and October of 2016. The applicant is not proposing any permanent impacts to wetlands with this project. Comments: 1. Applicant shall show buffers for the wetlands as established by VLAWMO’s MnRAM. The 75FT buffer width is shown along Lake Amelia (Wetland A). Wetland B is a Manage 2 wetland, which calls for a Base Buffer Width of 30 FT. Although buffer slopes and soils may allow a narrower base width, we conservatively assume that 30 FT is also the applied buffer width. This results in an overall required buffer area of 25762 SF. Consistent with VLAWMO rules, the buffer width for Wetland B was reduced in some areas (to no less than 15 FT, i.e., 50% of the Base Buffer Width) and expanded in other areas (to no more than 60 FT, i.e. 200% of the Base Buffer Width) to accommodate site conditions. The resulting proposed buffer area around Wetland B is 26240 SF, exceeding the area of habitat protection corresponding to the Base Buffer Width. Wetland D is a Preserve wetland, which calls for a Base Buffer Width of 75 FT. Although buffer slopes and soils may allow a narrower base width, we conservatively assume that 75 FT is also the Applied Buffer Width. Not considering off-property area of the area protected separately within the shoreland impact zone, this results in an overall required buffer area of 131578 SF. Consistent with VLAWMO rules, the buffer width for Wetland D was reduced in some areas (to no less than 37.5 FT, i.e., 50% of the Base Buffer Width) and expanded in other areas (to no more than 150 FT, i.e. 200% of the Base Buffer Width) to accommodate site conditions. The resulting proposed buffer area around Wetland D is 141952 SF, exceeding the area of habitat protection corresponding to the Base Buffer Width. Wetlands C and E are Manage 2 wetlands, which calls for a Base Buffer Width of 30 FT. Constant width (30 FT) buffers have been shown for both wetlands. 2.Show all proposed wetland buffer signs on plans (see preliminary plat) •Landscaping Restoration and rain garden/basin plant listing is reviewed by the City’s Environmental Coordinator. •Floodplain There is existing floodplain on Lake Amelia Woods along Amelia Lake. It is identified as Zone AE with a base flood elevation of 910.2. The applicant is not proposing any grading or building within the floodplain. Lake Amelia Woods Final Plat Engineering Review Ms. Katie Larsen 9/3/2025 Page 7 Comments: 1.Applicant should modify the legend to identify the floodplain line on the plans. The floodplain line has been added to the legend. Applicant to clarify in the legend that the floodplain line is the same as the HWL. Legend has been updated as indicated. •Drainage and Utility Easements th The applicant is proposing 10-ft wide drainage and utility easements along the 20 Avenue (CSAH 54) right-of-way. The applicant is proposing 5-ft wide drainage and utility easements on adjacent property lines between lots. Per City Code, the City requires 10-ft wide drainage and utility easements along lot lines and allows these easements to be centered on common rear and side lot lines. Comments: 1.Applicant shall provide the following Drainage and Utility (D&U) Easements: th a.A 20-ft wide D&U easement along 20 Avenue (CSAH 54) beyond the right of way will be required for future water system looping b.All side lot lines require 10-ft D&U easements c.D&U easements along Amelia Lake shall be along the delineated wetland + 10ft or floodplain 100 yr elevation + 10 ft (whichever is greater) d.All wetlands require a D&U easement 10 ft from the delineated boundary Applicant to update the north D&U boundary for the southernmost wetland on Lot 4. It does not appear to extend all the way to the right-of-way and/or the D&U easements adjacent to the right-of-way. e.All stormwater facilities require a D&U easement 10-ft from the HWL Easements have been updated and shown as indicated. th 2.Applicant to provide a 20-ft wide trail easement along 20 Avenue (CSAH 54) that shall be recorded with the final plat in the same location as the D&U for the water system looping The trail easement is shown as a drainage and utility easement on the preliminary plat. Sketch and description to be prepared upon approval of location and placement. That location is correct. The trail easementshall be recorded as a separate document with the final plat. See private easement sheet (S6). Development Agreement A Development Agreement will be required with the final plat. Grading Agreement A Grading Agreement is not applicable at this time. •Stormwater Maintenance Agreement The stormwater ponds will be privately maintained and a Stormwater Maintenance Declaration will be required with the final plat.

Lake Amelia Woods Final Plat Engineering Review Environmental Memo To:Katie Larsen, City Planner From:Tom Hoffman, Environmental CoordinatorTom Hoffman, Environmental Coordinator Date:September 2, 2025 Re: Environmental Comments – Lake Ameila Woods Preliminary Plat Staff has reviewed the submittals and had recommended the following: 1. Redundant erosion control where at 50’ natural vegetation buffer cannot be maintained to wetlands, floodplain, or lake shore. a. Erosion control should be spaced 3-5’ to prevent erosion and sedimentation. b.A buffer should be maintained along the wetland on lot three and the proposed silt fence and grading. Current plan shows silt fence and grading up to the edge of the wetland. This will most likely result in some sedimentation and fill. To prevent wetland impacts pull back the silt fence and grading to allow for a buffer. 2.Natural net erosion control blanket shall be used in all areas and called out in the SWPPP 3.Provide MN DOT seed mixes for each type of proposed vegetation. Native weed free seed should be used to provide pollinator habitat. 4.Site ultimately discharges to Wilkinson Lake, which is an impaired water body within 1 mile of the project location. Wilkinson is not shown as impaired on the resource map in the SWPPP 5.Tree survey and approved tree plan is the same from the original plat. a.Update tree survey with current proposal b.Tree removal should decrease significantly with the removal of the stormwater features. 6.Provide energy dissipation at driveway culverts or provide storm calcs showing its not necessary. 7.Provide impervious surface calculations for each lot within the proposed development. Overall site is being shown at 0.98 acres. a.Impervious calculations should include proposed accessory structures, patios, and additional hardcover on the lot.

ISG Response (6/9/2025) WSB Response (6/20/2025) ISG Response (7/14/2025) WSB Response (8/6/2025) WSB Response/Comment (9/4/2025) Engineering •General The Wilkinson Waters Development includes 76 acres south of Ash Street/County Road 32, West of Centerville Road/County Road 21 and north of Wilkinson Lake Boulevard, the border with the City of North Oaks. The current conceptual project proposes 56 Townhome units, two (2) 100-unit apartments, one (1) 100-unit senior living facility and 33,000 square feet of commercial retail space. Comments: 1.Increased height has been requested for the buildings and it appears that they are already being raised quite a bit from the existing topography Ms. Katie Larsen 09/04/2025 Page 2 a.Provide what the need is for having the floor elevations as high as they are proposed for the buildings. •Grading The Wilkinson Waters Development includes site grading for the townhomes, apartments, and retail space as well as the connecting roads, driveways, and parking areas. Comments: 1.Site should be designed to better match existing grades. Lowering the site approximately 5 feet from what is proposed. The applicant should consider an underground subsurface drainage system. ISG Response (7/14/2025) Further testing is being conducted on site to determine the groundwater elevations. Grading will be updated per results of these tests. WSB Response/Comment (9/4/2025) In process 2.Provide EOF elevations, locations and routes for all low points in the paved and greenspaces. ISG Response (6/9/2025) – EOF elevations have been added to the Grading Plan. WSB Response (6/20/2025) – EOF elevations are in compliance with freeboard requirements. ISG Response (7/14/2025)ISG Response: EOF elevations have been added to the Grading Plan. WSB Response/Comment (9/4/2025) Additional EOFs are still required for low points in the roadway and greenspaces. Note impact of downstream EOFs being higher than upstream EOFs. 3.Retaining walls exceeding 4’ in height shall require a plan prepared by a Minnesota licensed structural engineer submitted for review and approval by the Building Official prior to permit issuance a.Provide top and bottom of wall elevations at beginning and end of wall, at point of maximum height, and at points along the length of wall to adequately describe the retaining wall and to display final grading accurately. b.Retaining walls are not allowed in easements or public rights-of-way c.Provide fences for safety as required ISG Response (7/14/2025)Noted, safety fence has been added to all walls over 4’ of height WSB Response/Comment (9/4/2025) Additional instances required on plans 4.Show all high and break points ISG Response (7/14/2025)Updated spot elevations to callout high points and break points WSB Response/Comment (9/4/2025) Additional instances required on plans 5.Label all inlet elevations ISG Response (7/14/2025)All inlet elevations at structures have been added to the plans WSB Response/Comment (9/4/2025) Additional instances required on plans 6.Provide slopes across parking areas and along curbs Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 3 ISG Response (7/14/2025)Slopes for parking areas have been added to the plans, curb slope labels will be added in the future when the scale of the plan sheets are smaller WSB Response/Comment (9/4/2025) Complete 7.Minimize drainage areas to all underground parking entrances a.Provide overflow options ISG Response (7/14/2025)Drainage to parking garage entrance has been minimized as much as feasible, overflow options for the garage entrances have been updated to provide an EOF to the adjacent greenspace WSB Response/Comment (9/4/2025) EOFs need to meet freeboard requirements •Stormwater Management Stormwater management for the Wilkinson Waters site consists of a large sedimentation basin and various smaller BMPs to provide additional treatment. There is also a proposed future public street that must meet City design standards. Existing and proposed discharge rates are summarized below. Pre- and Post- Development Discharge Rates (cfs) Condition2-Year10-Year100-Year10-Day Snowmelt Needed if basins Existing24.1255.09125.90 landlocked Currently Needed if basins 16.1341.84123.94 Proposedlandlocked Comments: 1.Compliance with stormwater requirements will be reviewed by the City. However, any wetland impacts must be permitted through the LGU for the site, VLAWMO. ISG Response (7/14/2025) – Noted, wetland impacts are permitted through VLAWMO. WSB Response (8/6/2025) – Comment addressed. WCA permit noted. 2.Per NURP design criteria, sedimentation basins must provide dead storage of at least the 2.5” storm event volume of runoff from the tributary area. The 2.5” storm event must be provided in future modeling to ensure compliance with this standard. a.If this standard is met, additional pretreatment such as the SAFL Baffles and rain gardens are not needed. These pretreatment BMPs are recommended to be removed if Basin 1 is sufficiently sized so as to reduce future maintenance needs. MIDS modeling is also not needed if Basin 1 is demonstrated as meeting NURP design criteria. ISG Response (6/9/2025) – After discussion, pretreatment will be kept in place. WSB Response (6/20/2025) – Dead storage confirmed with modeled 2.5” event. Keeping pretreatment is welcome in providing additional rate control and pollutant removals. 3.A surface water reuse system is required. Rice Creek Watershed District staff may be able to supply a water reuse spreadsheet for use in calculating water reuse rates and areas for the site. ISG Response (7/14/2025) – Noted, will reach out to RCWD for their reuse spreadsheet to add in the design, the feasibility report for Water Reuse on the sight is Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 4 being completed by Water in Motion and will be supplied to the City and VLAWMO for review. WSB Response (8/6/2025) – Noted, please provide water reuse report when available. 4.The steepest allowable slope below the 10’ aquatic bench is 3:1. Current grading of 2:1 is too steep and must be revised. ISG Response (6/9/2025) – Grading below the aquatic bench was revised to 3:1 slopes. WSB Response (6/20/2025) – Comment addressed. 5.The outlet pipe for Basin 1 must be submerged at least 1’ below the NWL. a.Considering this basin is intended for irrigation reuse, the outlet pipe should be set such that it is submerged even at the lowest planned water elevation. ISG Response (7/14/2025) – Invert of the outlet pipe has been updated. WSB Response (8/6/2025) – While submerged for the stated NWL, outlet pipe invert should be set according to lowest planned water elevation in the water reuse report. WSB Response (9/4/2025) – Remains an open comment. 6.An impervious clay liner should be specified below Basin 1 as geotech borings in and around the pond show some sandy/silty soils that may infiltrate water meant for irrigation reuse. This will be evaluated with the next submittal. ISG Response (6/9/2025) – Noted. WSB Response (6/20/2025) – Clay liner noted on pond detail. 7.Tree plantings are not recommended on the Basin 1 berm as root growth may weaken its integrity over time. ISG Response (7/14/2025) – Noted, tree plantings have been removed from the top of the berm.. WSB Response (8/6/2025) – Comment addressed. 8.All BMPs and site depressions need to show EOF locations and elevations. ISG Response (6/9/2025) – Addressed. WSB Response (6/20/2025) – EOFs shown. 9.Curb cuts must have rock stabilization over the flow path to BMPs. ISG Response (7/14/2025) – Addressed. WSB Response (8/6/2025) – Comment addressed. 10.Wilkinson Way will be a public road so inlet spread and run calcs, in particular at sag points, must be provided and ensure an 8’ drivable lane during the 3-year storm event. ISG Response (7/14/2025) – Storm sewer inlets spread calculation was calculated using the 3-yr stm event, calculations are included in the stormwater report. WSB Response (8/6/2025) – Provided calculations do not include spread extents. Intake efficiency does not indicate how far into the roadway water will spread during the storm event. Additionally, allowable sag depths of 0.5’ and 1’ would result in ponded water up to and over the crown of the road per the given typical section. This does not provide a center 8’ drivable lane. The provided calculations also appear to be for a 10-year event, not 3-year. WSB Response (9/4/2025) – Remains an open comment. 11.All proposed pipe serving Wilkinson Way must have supporting calculations to ensure there is capacity for conveying the 10-year storm event. ISG Response (7/14/2025) – Storm sewer was sized using the 10-yr stm event, calculations are included in the stormwater report. WSB Response (8/6/2025) – Comment addressed, pipe capacity is sufficient.. 12.The maximum pipe velocity is 10 ft/sec and the minimum is 3 ft/sec. ISG Response (7/14/2025) – Noted, these design considerations have been addressed. WSB Response (8/6/2025) – Comment addressed. Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 5 13.The City minimum storm sewer size for public roads is 15” and must be RCP. Include storm sewer pipe material on utilities sheets. a.Pipe from ST-108A to ST-108 must be increased to 15” diameter. ISG Response (7/14/2025) – Storm Sewer within roadway has been updated to be a minimum of 15”. WSB Response (8/6/2025) – Comment addressed. 14.Structure types and sizes should be called out for Wilkinson Way storm sewer. ISG Response (7/14/2025) – Structure Types and Sizes for sewer within Wilkinson way have been added to the plans. WSB Response (8/6/2025) – Comment addressed. 15.Show storm sewer in profile view along Wilkinson Way to ensure there are no utility conflicts. a.Utility crossings should be checked across the site to ensure there are no conflicts and to call out insulation as needed. ISG Response (7/14/2025) – Storm Sewer has been added to the profile of Wilkinson Way on the Final Plans. WSB Response (8/6/2025) – Comment addressed. No conflicts appear to be present and insulation is called out in storm profile view. 16.Ensure structure diameters are sized properly for alignments with pipes at acute angles or with large diameter pipes. ISG Response (7/14/2025) – Storm Structure diameters were updated. WSB Response (8/6/2025) – Check constructability of structures with large diameter (>21”) pipes. For example, ST-202 with a 36” RCP and 42” RCP at 90° is not likely constructable as a 48” structure. WSB Response (9/4/2025) – Remains an open comment even though pipes into ST- 202 have changed. 17.What is the purpose for structure ST-2? ISG Response (7/14/2025) – ST-2 was removed per grading updates. WSB Response (8/6/2025) – Comment addressed. 18.How will the low points at driveways into Buildings A and B be drained? ISG Response (7/14/2025) – Trench drains were added to the utility drawing. WSB Response (8/6/2025) – Comment addressed. 19.Indicate tip-out gutter as needed to ensure pooling is avoided in upgradient portions of parking lots. ISG Response (7/14/2025) – Reverse curb gutter callouts have been added to the plans. WSB Response (8/6/2025) – Comment addressed. 20.ST-304 should be moved to the corner of the nearest parking stall rather than on the curb radius. ISG Response (7/14/2025) – ST-304 was moved to the end of the nearest parking stall. WSB Response (8/6/2025) – Comment addressed. 21.It is recommended to route ST-201 directly to FES-4A to avoid daylighting drainage and potentially flooding onto the proposed trail. ISG Response (6/9/2025) – Storm Sewer was updated to convey stormwater directly to the basin. WSB Response (6/20/2025) – Comment addressed. 22.The OCS details on sheet C0-26 do not match HydroCAD modeling. ISG Response (6/9/2025) - Detail has been updated to match the HydroCAD modeling. WSB Response (6/20/2025) – The weir wall is modeled as 5’, though the detail shows a 6’ diameter structure. Additionally, the rain garden outlet rim elevations/pipe Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 6 inverts/pipe sizes do not match between the provided plans and HydroCAD modeling. Ensure these match in future submittals. WSB Response (9/4/2025) – Remains an open comment. 23.HydroCAD modeling has a 36” pipe from OCS-2 to FES-6, however this is shown as a 30” pipe in the plans. ISG Response (6/9/2025) – OCS-2 has been removed from plans. WSB Response (6/20/2025) – Noted. 24.HydroCAD modeling of OCS-2 has a 5’ wide weir, but a 6’ wide grate. Please reconcile these differences. ISG Response (6/9/2025) – OCS-2 has been removed from plans. WSB Response (6/20/2025) – Noted. 25.Use native prairie seed mix on Basin 1 slopes. ISG Response (7/14/2025) – Noted, high maintenance turf has been replaced with prairie seed mix on Basin 1 slopes. WSB Response (8/6/2025) – Planting plans on the plat set and public plans still show turf hatching along Basin 1 slopes above the NWL. Additionally, please include a legend item in the private plans for seeding type over the proposed rain gardens. WSB Response (9/4/2025) – Remains a partially open comment. The rain garden seeding comment has been addressed, though turf seeding is still shown along Basin 1. 26.Deconflict storm sewer and proposed trees to the extent practical, overlap of planting can result in root intrusion long-term, especially where trees are proposed near structures. ISG Response (7/14/2025) – Noted, utility revisions and tree location adjustments have been made and accommodated for. WSB Response (8/6/2025) – Comment addressed. 27.WSB Response (8/6/2025) – The proposed conditions rates do not match between the HydroCAD report and Table 5 of the Stormwater Report. WSB Response (9/4/2025) – Remains an open comment. •Water Supply The City’s 2040 Comprehensive Plan identifies this area being served by Lino Lakes via a 12” trunk water line. Lino Lakes City water is about 1.5 miles away and the City is not considering an extension at this time. In the interim the site will be supplied by the existing White Bear Lake Township infrastructure that is located across the Rapp farmland in Lino Lakes and into the north end of North Oaks. This will require a Joint Powers Agreement between all of the Cities involved. The development proposes two connections. A 12” connection at the south end on the west side of the proposed roundabout which will be extended along Wilkinson Way north to the north end for a future connection to Ash Street (CR 32) to meet the City’s 2040 Comprehensive Plan. The second connection will utilize the existing 8” stub as part of the existing assumed White Bear Lake Township infrastructure that is located across the Rapp farmland in Lino Lakes . Otherwise, the development will include a water system with 8- inch diameter water main and various stub sizes being extended to each lot depending on its use. Current and future ownership and maintenance of all existing utility infrastructure will need to be clarified between the developer North Oaks Farms, White Bear Lake Township, and the Cities of North Oaks and Lino Lakes. Comments: Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 7 1.Remove the proposed 12” gate valve on the north leg of the tee. The gate valve will be installed with the future extension of the line to the north. ISG Response (7/14/2025)Gate valve was removed. WSB Response/Comment (9/4/2025) Complete 2.The existing watermain stub at the roundabout is 12” not 8” ISG Response (7/14/2025)Noted, call out has been updated to a 12” existing line WSB Response/Comment (9/4/2025) Complete 3.Locate proposed gate valves consistently on all water service stubs ISG Response (7/14/2025)Gate valve locations have been updated to be consistent on all water service stubs WSB Response/Comment (9/4/2025) Complete 4.Label all water service stub size, length, and material ISG Response (7/14/2025)Labels for the watermain has been updated to show size, length and material WSB Response/Comment (9/4/2025) Complete 5.Provide minimum 1:1 easement for watermain outside the right of way (minimum 20' centered on the utility) ISG Response (7/14/2025)Easement lines have been updated to provide 20’ minimum or 1:1 easement for watermain outside of the ROW WSB Response/Comment (9/4/2025) Watermain around Block 1 requires additional easement at bend points 6.Extend utilities a minimum 10' past the storm sewer at the Ash Street intersection ISG Response (7/14/2025)Utility stubs have been extended past the culvert at the Ash Street intersection WSB Response/Comment (9/4/2025) Complete 7.Shift gate valve from northern leg to southern leg of 12” x 8” cross ISG Response (7/14/2025) Gate valve has been shifted to the south leg of the cross WSB Response/Comment (9/4/2025) Complete 8.Maintain minimum required 10’ horizontal separation between watermain and storm sewer alignments ISG Response (7/14/2025)Watermain alignment was updated to provide 10’ of separation around storm sewer structures WSB Response/Comment (9/4/2025) Areas still do not meet minimum separation requirements (see redline comments) 9.Note separation between sanitary sewer and water services across Wilkinson Way a.Some services will need to be shifted to maintain separation. ISG Response (7/14/2025)Note was added to plans calling out the separation between services. Plans are showing a typical separation of 11’ WSB Response/Comment (9/4/2025) Cross services are still close together. Discussion with Public Works 10.WSB Response/Comment (9/4/2025) Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 8 •Sanitary Sewer Sanitary sewer collection for the Wilkinson Waters Development is proposed to connect to the existing assumed White Bear Lake Township infrastructure that is located across the Rapp farmland in Lino Lakes. There is also an existing 18 inch sanitary sewer line located at the intersection of Wilkinson Lake Blvd/CR J (81)/CSAH 21 that is believed to be owned and maintained by White Bear Township as well and is planned to serve Lino Lakes sewer district 4. This will require a Joint Powers Agreements between the developer North Oaks Farms, White Bear Lake Township, and the Cities of North Oaks and Lino Lakes. Per the Centerville Road Sanitary Sewer memo updated 4/22/21, the City of Lino Lakes service district 4 has 354 GPM capacity reserved in the Centerville Road trunk line. There is an additional lift station planned in the future to serve the remainder of district 4 that will pump into the 18” line located at the intersection of Wilkinson Lake Blvd/CR J (81)/CSAH 21. This forcemain can be drilled within City or County right of way in the future. The 8 inch line that is being required to extend to Ash Street would only serve a small localized area of sewer district 4. The City would be open to extending the 18 inch through the site to serve as much of the development as possible. However, due to depth, the senior apartments would still need to be connected to the deeper 8 inch line as proposed. A future forcemain tie in to the 18 inch would need to be accommodated. This will be further evaluated through the preliminary plat process. The site will otherwise be served by 8- inch diameter main along with various sized service pipes being extended to each lot depending on its use. An additional sanitary sewer stub will be extended to the north at Ash Street (CR 32) for future connections. Current and future ownership and maintenance of all existing utility infrastructure will need to be clarified between the developer, White Bear Lake Township, and the Cities of North Oaks and Lino Lakes. Additionally calculations will need to be made for the increased flows to the existing lift station in North Oaks and whether upgrading of the pumps will need to occur. Comments: 1.Extend the existing 18" sanitary sewer stub outside the roadway into right of way as shown in the attached redlines ISG Response (7/14/2025)Sanitary sewer stub has been extended to the ROW WSB Response/Comment (9/4/2025) Connection has been recently updated and is under separate review 2.Provide minimum 1:1 easement for watermain outside the right of way (minimum 20' centered on the utility) a.The sanitary sewer between Lots 3 and 4 Block 1 would require a 40’ total easement ISG Response (7/14/2025)Easement lines have been updated to provide 20’ minimum or 1:1 easement for sanitary sewer outside of the ROW WSB Response/Comment (9/4/2025) Complete 3.Extend utilities a minimum 10' past the storm sewer at the Ash Street intersection ISG Response (7/14/2025)Utility stubs have been extended past the culvert at the Ash Street intersection WSB Response/Comment (9/4/2025) Complete Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 9 4.Maintain sanitary sewer manholes on road centerlines ISG Response (7/14/2025)Sanitary sewer manholes are maintained on the roadway centerline. Sanitary manholes are placed adjacent to the median to avoid conflicts with tree planting within median WSB Response/Comment (9/4/2025) Shift sanitary manholes to median or to center of drive lanes 5.Applicant to verify existing Lift Station has capacity for proposed project ISG Response (7/14/2025)Noted, Sanitary Sewer Lift Station Memo has been Submitted WSB Response/Comment (9/4/2025) Address previous comments and revise Lift Station Memo 6.WSB Response/Comment (9/4/2025) •Transportation Ensure City parking space requirements are met and ADA spaces are all marked on the site plan.

WSB Response (9/4/2025) – Signing and striping comments provided on 8/6/25 have not been addressed. •Wetlands and Mitigation Plan The Vadnais Lake Area WMO (VLAWMO) (WCA LGU) issued a Notice of Decision (NOD) (LGU No. 14.2021) approving the wetland boundaries on March 17, 2022 (Appendix A). The decision is valid for 5 years. The WCA NOD also confirmed that Wetland 7 is an incidental wetland and therefore not regulated-under WCA. The USACE issued an Approved Jurisdictional Determination (AJD) on April 6, 2022 for Wetlands 8, 9 and 10 (File No. MVP-2015-03940-SSC) (Appendix A). The AJD is valid for 5 years. A map of the site location is provided in Figure 1. Three wetlands (Wetlands 1, 7, and 10) were delineated within the current project area in September 2021 by KES (Figure 2). Previously submitted information discussed the delineation in more detail and included the National Wetland Inventory (NWI) and soil survey mapping. A copy of the previously submitted delineation report (Hawkins-Rogalla Lino Lakes Wetland Delineation Report) is available upon request. A wetland replacement plan and no loss request (for incidental wetland) was submitted, reviewed, and approved through VLAWMO and the City. The TEP in its WCA Notice of Decision agreed that WL7 is incidental per WCA rules, WL10 is wetland based on new guidance and the WL5 boundary was extended to the northwest. Per aerial photos in 3-9- 2022 addendum, WL9 and WL8 are wetland. No other changes were directed to all other delineated wetland boundaries in the project area. Approved wetland boundaries are shown in the 3-10-2022 Rogalla and Hawkins surveys from Kurth Surveying, Inc. The proposed WCA-regulated 0.13 ac of impact to Wetland 10 will be replaced at a 2:1 ratio via the debiting of wetland bank credits from the Rapp Farm and Anderson Slough wetland bank (#170) located within major watershed 20 and Bank Service Area 7, which is the same major watershed and Bank Service Area as the project location. This bank is owned by the project applicant. A draft Standard Credit Withdrawal Form is included. Compensatory mitigation is not proposed for USACE-regulated Wetland 7. Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 11 Wetland buffers meeting minimum and average requirements will be required around all wetland areas following construction. •Landscaping A Landscape Plan for Wilkin son Waters Addition has been submitted and will be reviewed by staff and the City’s Environmental Coordinator. The Environmental Coordinator will provide separate comments. •Floodplain The proposed pond berm and trail grading appears to result in floodplain fill. Calculation of compensatory cut must be provided to ensure there is no net fill in the floodplain. This remains an open comment. A one-time deposition of 100 cubic yards of floodplain fill is allowable, fill in excess of this volume requires compensatory cut within the floodplain. •Drainage and Utility Easements Roadways are proposed within right-of-way and lots include standard drainage and utility easements. Larger drainage and utility easements will be required to be provided over any utilities outside the right of way and any surface water management features The plan shows White Bear Lake Township easements (30’ and 50’) with the existing sanitary sewer and watermain crossing the site. White Bear Lake Township has commented that the Township has no easement and that the lines were installed and owned by the North Oaks Company. Please update the linework or provide a record showing the easements. Comments: 1.For pipe within drainage and utility easements that is greater than 10’ deep, easements must be set with a width equal to the pipe depth. For example, a 20’ deep pipe would require 20’ wide easements on either side of the alignment. a.This appears to be needed for P-101, P-102, P-111, P-110, and P-202. ISG Response (7/14/2025) – Easement lines have been updated to provide 20’ minimum or 1:1 easement for storm sewer outside of the ROW. WSB Response (8/6/2025) – D&U must be expanded between L4 B1 and L5 B1 to accommodate the >10’ pipe depth between ST-110 and ST-109. D&U must be expanded between L1 B1 and L2 B1 to accommodate the >10’ pipe depth between ST-202 and ST-201. WSB Response (9/4/2025) – Remains an open comment. 2.Drainage and utility easements are needed for all proposed rain gardens up to the extents of the 100-year HWL. ISG Response (7/14/2025) – D&U easements have been added around proposed raingardens. WSB Response (8/6/2025) – Please specify document showing these easements, none are evident on sheet A0-16 of the Preliminary Plat Plan Set. WSB Response (9/4/2025) – Remains an open comment. 3.Provide existing easement figure showing all ownership Wilkinson Waters Development - Engineering Review Ms. Katie Larsen 09/04/2025 Page 12 ISG Response (7/14/2025)Easement have been included on the Preliminary Plat and Final Plat documents WSB Response/Comment (9/4/2025) Create exhibit that clarifies of whom each easement is in favor 4.Conservation easements and wetland buffers shall be dedicated over wetlands, ditches, and the greenway 5.ISG Response (7/14/2025)Easement has been added to the greenway corridor and wetland buffer 6.WSB Response/Comment (9/4/2025) Easements not shown on plat – Exhibits under review Development Agreement A development agreement will be required with the final plat.

Wilkinson Waters Development - Engineering Review Environmental Memo To:Katie Larsen, City Planner From:Tom Hoffman, Environmental CoordinatorTom Hoffman, Environmental Coordinator Date:September 3, 2025 Re: Environmental Comments – Wilkinson Waters PPP PP Environmental Board had recommended the following at their March 26, 2025 meeting: 1.Complete the noise mitigation study and submit findings if any additional berming or screening is required. 2.Building setbacks to Wilkinson Lake as proposed should be maintained. 3.Work with planning and zoning on building heights. Currently building heights exceed the requirements for the shoreland district. a.Board recommends additional overstory planted adjacent to buildings that exceed the requirements for additional screening and sight lines. 4.Stormwater management to be reviewed by City Engineer a.Use of stormwater for irrigation purposes for the site should be evaluated and if feasible required as part of site development. i.Water balance study is being conducted b.Infiltration is required to be shown where feasible based on soil borings. If infiltration is not feasible follow the Minimum impact design standards (MIDS)) as designed by the MPCA i.Infiltration basins are shown for pretreatment of parking lot runoff. c.Currently private drainage from parking lots is by passing pre-treatment basins within the parking lot and discharging into the stormwater basins. Any private drainage must first be treated prior to discharge into a public stormwater basin. i.If private drainage cannot be treated prior to discharge the basins shall be privately maintained. 5.Storm sewer between town homes should discharge between the buildings into a swale before continuing west to the drainage swale and entering the storm basin. a.Creating water features between the buildings with native plantings and vegetation will provide a higher level of stormwater treatment and create “fingers of green” running through the site to enhance wildlife habitat. b.Storm sewer between town houses should be relocated for future maintenance and access. Feasibility of replacing that pipe in the future will create access issues. Pipe should remain private if public access isn’t available for future work. i.Remove one or both pipes between town house crossings or provide alternative for future maintenance 6.The project should include expanded buffers adjacent to Wetland 1. A restoration and management plan should be developed for upland buffer areas consistent with pre-settlement vegetation. 7.Trees scheduled to be preserved must have Tree Protection Fence installed in accordance with City tree protection fence detail. City Tree Protection Fence detail should be added to the plan sheet. Standard detail Gen-27. 8.Tree removal should be completed in the fall or winter to minimize impacts to migrating or nesting bat populations. 9.Provide ESA classification and basic use designation for the 57 trees being removed. It appears that several of the trees will be larger than 12” in diameter and would require a 2:1 replacement planting. a. b.Plans show removal of 38 trees of which 30 are significant. Clarify total number of removals. c.On the removal plans add the tree identification number so we can correlate it with the tree inventory. d.Coniferous trees are shown as measured by DBH, city standards measure coniferous trees by height. Please provide height measurements for all coniferous trees planned to be removed. 10. Plant additional “large” canopy trees on the backside of the proposed senior living building within the shoreland district. Page 2 a.Increased heights of proposed building should include additional screening on the backside of the building to break up the outline from the lake. 11.Sheet C5.13 should include the species of trees proposed to be planted instead of large, medium, and small. a.Provide numbers for each species of tree to be planted. 12.Seed mixes should be updated to MNDOT seed mix design numbers for final plans. Please provide more site-specific mixes for each location. a.Low maintenance and drought resistant species should be proposed throughout the development to reduce the need for irrigation. 13. 4” minimum of topsoil is required for final planting of all ground covers, seed, and sod. Soil shall be loosened and prepped to a minimum depth of 4” to reduce compaction and allow for root growth. 14.The proposed trail should make a loop in the open space area and run along ash street before connecting back into Wilkinson way. a.Currently the trail is proposed to dead end in the park/open space. Opportunities for additional trail exist throughout the park. Potentially linking the trail system through any future proposed bmp as part of the VLAWMO BMP study. 15.The project will disturb more than an acre of soil and will be required to obtain an NPDES permit. Proof of permit shall be required before construction. a.A SWPPP shall be required in additional submittals as required by the MPCA meeting sections 5.2-5.26 b.Final erosion and sediment control will be reviewed with future submittals 16.Provide a Blandings turtle mitigation plan, surmountable curb should be proposed within the roadway to allow turtles access off the road for travel.

The preliminary plat was previously titled th Erickson Property. The applicant proposes to subdivide the existing lot located at 7590 20 Avenue into 14 single family lots. Tentative Review Schedule: Complete Application Date:August 12, 2025 60-Day Deadline:October 11, 2025 Environmental Board Meeting:N/A Park Board Meeting:N/A Planning & Zoning Board Meeting:September 10, 2025 City Council Work Session:October 13, 2025 City Council Meeting:October 13, 2025 This staff report is based on the following information: Hampton Addition Plan Set prepared by Landform revision date August 11, 2025 Hampton Addition Final Plat prepared by Landform received on August 11, 2025 1 Temporary Cul-de-sac Easement Exhibit prepared by Landform received on August 11, 2025 Title Commitment dated August 4, 2025 BACKGROUND On July 14, 2025, the City Council passed Resolution No. 25-93 approving the preliminary plat. The Council staff report and resolution detail the project’s consistency with the City’s Comprehensive Plan and compliance with the City Code. This staff report provides updates to the July 14, 2025 Council staff report related to the preliminary plat. Changes are either narratively described or shown as strikethrough (deletions) or underline (additions). ANALYSIS Preliminary Plat The preliminary plat contains 14 lots and 1 outlot. The outlot is for stormwater management. The outlot will be owned by an HOA the City and the stormwater pond will be maintained by the City. The original plan set included a retaining wall on the two north lots. These retaining wall were going to be maintained by an HOA. This retaining wall has been removed on the revised plan set. If it is determined the retaining walls are still required, the property owners of the two lots shall be responsible for the maintenance. Final Plat The final plat contains the same 14 lots and 1 outlot. Phasing Plan The development is proposed to be constructed in one (1) phase. Public Land Dedication The City will require cash in lieu of land dedication. At the July 7, 2025 Council Work Session, the Council requested all 14 lots pay park dedication fees. After consulting with the City Attorney, it was determined this would be reasonable since the existing house did not pay park dedication fees. The Council also requested the trail be constructed at this time by the developer. Trail construction costs will be credited to the developer. 2 Hampton Addition Total # Units =14 x Park Dedication Fee$3,500 = Cash in Lieu Value$49,000 (Trail Construction Costs)($12,078) TOTAL CASH FEE DUE =$36,922 Title Commitment The City Attorney will review the title commitment and final plat prior to Council approval of the final plat. Agreements Stormwater Maintenance Agreement The private stormwater facilities will be maintained through a Declaration for Maintenance of Stormwater Facilities. Development Agreement and Final Plat A Development Agreement will be prepared by the City and shall be executed. Site Improvement Performance Agreement Not applicable.

Existing and proposed discharge rates are summarized below. Pre- and Post- Development Discharge Rates (cfs) Condition2-Year10-Year100-Year10-Day Snowmelt Only needed if Existing9.6415.2332.09 basins landlocked Currently Only needed if 4.316.4612.40 Proposedbasins landlocked Comments: 1.This development falls within the Northeast Drainage Area Comprehensive Stormwater Management Plan (CSMP) area and as such is beholden to additional rate control and volume reduction requirements. Landform Response (8/11/25) – Proposed outlet structure has been re-routed to the existing south pond (Pond 500). See updated plans & stormwater report. 2.The pond south of this development was constructed with the Watermark development and designed to include runoff from the Erickson Property. If rates are reduced or maintained from existing conditions, volume control provided in the form of stormwater reuse, and water quality treatment provided by the proposed pond, it is recommended to overflow the onsite pond south to the existing Pond 500 (NWL 899, HWL 904.3). This allows the proposed development to meet CSMP rate control requirements by utilizing the existing Watermark system that already meets requirements. Landform Response (8/11/25) – Proposed outlet structure has been re-routed to the existing south pond (Pond 500). See updated plans & stormwater report. 3.Why does PB-3 have water surface land cover modeled in HydroCAD? Landform Response (8/11/25) – This should have been Type D soils. Updated. 4.The pond EOF must include riprap stabilization. Landform Response (8/11/25) – Updated. See Plans. 5.The modeled pond EOF of 906.5 does not reflect the EOF of 905.57 in the plans. Landform Response (8/11/25) – Model has been updated with an EOF of 905.57. 6.A detail must be provided for the pond outlet control structure. Landform Response (8/11/25) – Plan and profiles have been included. WSB Response (9/3/25) – The pond skimmer structure must include the rim elevation and must match the grate modeled in HydroCAD. The submerged 12” pipe Erickson Property Development - Engineering Review Ms. Katie Larsen 09/03/2025 Page 4 is recommended to have an invert of 900 to ensure it remains submerged when the pond is drawn down for irrigation. 7.The 10’ aquatic bench should continue around the entire pond. If that is not feasible, the bench should at least be on the eastern side of the basin to provide a safety bench for residents. Landform Response (8/11/25) – Aquatic bench has been moved from western side to eastern side of pond. 8.Provide calculations demonstrating spread at the catchbasin low points is 10’ or less for the 3-year storm event. Landform Response (8/11/25) – See storm Calcs. 9.Rational method pipe capacity calculations must be provided showing storm sewer is sized to convey the 10-year storm event. The minimum pipe diameter is 15”. Landform Response (8/11/25) – Updated. See storm calcs. WSB Response (9/3/25) – Pipes from CB-202 to FES-200 must be upsized to the 15” minimum. 10.The storm sewer draining to the pond must be raised to outlet at the pond NWL of 904. Landform Response (8/11/25) – Updated. 11.The pipe between the catchbasins is 18” diameter, but the pipe to the pond is 15” diameter. Resize one or the other to avoid flow constriction. a.This pipe sizing also does not match the pipes modeled in HydroCAD. Landform Response (8/11/25) – Updated. See storm calcs. 12.Confirm constructability of MH-119 as a 2x3 structure based on proposed pipe sizes and alignments. Landform Response (8/11/25) – Structure is now a 48" CBMH. 13.Mesic prairie seeding should continue down to the BMP NWL instead of southern boulevard. Landform Response (8/11/25) – The BWSR Mesic prairie seeding and the MN DOT Southern Boulevard see hatches were flip flopped. See revised plans showing Mesic prairie seeding down to the NWL. 14.WSB Response (9/3/25) – How will CBMH-201 and -202 be paved over with the temporary cul de sac? How will road drainage be routed during those conditions? •Water Supply The proposed Erickson Property water system extension is consistent with the original Watermark preliminary plat. This development will be served by 8- inch diameter ductile iron th pipe (DIP) water main which was stubbed with the Watermark 5 Addition and with 1-inch Type K copper services being extended to each lot. A future 8” stub will be provided on the th north end to connect to the 8” water stub provided on Osakis Street with the Watermark 6 Addition in the future.

Erickson Property Development - Engineering Review Environmental Memo To:Katie Larsen, City Planner From:Tom Hoffman, Environmental CoordinatorTom Hoffman, Environmental Coordinator Date:September 3, 2025 Re: Environmental Comments – Erickson Properties Preliminary Plat/Hampton Addition Final Plat Environmental Board recommended the following at their May 28, 2025 meeting: 1.Stormwater management to be reviewed by City Engineer a.Use of stormwater for irrigation purposes for the site should be evaluated and if feasible required as part of site development. Larger stormwater ponds constructed for fill should be evaluated for water reuse. b.Infiltration is required to be shown where feasible based on soil borings. If infiltration is not feasible follow the Minimum impact design standards (MIDS)) as designed by the MPCA 2.EOF should be shown as stabilized rock to prevent erosion of the stormwater pond. a.Trail should have rip rap or rock shouldering to prevent washout and undermining of the trail 3.Low maintenance turf should be evaluated throughout development. Ground covers should be drought resistant to reduce the need for irrigation use. 4. Provide a tree inventory for the site showing only significant deciduous trees of 6” in dbh or larger. Coniferous trees are measured by height, coniferous trees over 12’ would be considered significant. a.Coniferous trees should be measured by height not DBH. b.Remove off-site trees from the final tree inventory c.Mitigation table provided for trees outside of basic use. 5.On section 4.1, bold or change the color of the tree tags to be visible. 6.Current plans show Twelve (12) trees being removed for storm water ponding. Stormwater ponding is not included under the basic use area and therefore mitigation will be required of those removals. 7.Sheet L7.1 shows coniferous tree planting detail. No coniferous trees are being shown on the planting tables. Remove this detail if not in use. 8.On Block one lot one and block two lot seven, the trees are planted outside of the boulevard. The city is okay but noted there will not be future planting there. 9.Trees that are to be preserved should show tree protection (snow fence or silt fence) around the trees during construction. 10.Provide plantings in the rear of block two for screening from adjacent existing homes. 11.Provide calculations for open space requirements. 1 large tree and 2 large shrubs are required for every 2,500sf of open space. 12.Shrubs located in the rear lots of block 1 should be planted within the property boundaries for screening. Open space requirements will require the planting of shrubs within the outlot as well. 13.Seed mixes should be updated to MNDOT seed mix design numbers for final plans. Please provide more site-specific mixes for each location 14.Add inlet protection to catch basins on corner of Osakis and Norway lane 15.Add inlet protection to storm manholes adjacent to project site. 16.Provide redundant perimeter control along east boundary of project site adjacent to existing storm sewer. 17.The project will disturb more than an acre of soil and will be required to obtain an NPDES permit. Proof of permit should be required before construction. a.A SWPPP shall be required in additional submittals as required by the MPCA meeting sections 5.2-5.26 b.Final erosion and sediment control will be reviewed with future submittals c.FES 200 and FES 302 should show rip rap for energy dissipation. d.Site ultimately discharges to Peltier Lake, an MPCA Impaired water body within a mile of the site. i.Update SWPPP timelines to show stabilization requirements. Page 2 18.The project site falls within the I-35E AUAR study area. The proposed development will be required to meet all requirements of the AUAR including mitigation measures. 19.Tree removal should be completed in the fall or winter to minimize impacts to migrating or nesting bat populations 20.Provide a Blandings turtle mitigation plan, surmountable curb is provided to allow turtles access off of the roads. a.Blandings turtle flyer should be included with the plans and construction documents.
