The application proposes 11 lots in a low-density residential development at 4730 140th Street NE near the in- tersection of Rolling Oaks Circle NE and Bluebird Trail NE, south of County Road (CSAH) 42. The purpose of this public hearing is to consider a request for a Preliminary Plat and Preliminary PUD Plan for the subdivision of 11 single-family detached residential lots on approximately 5.38 gross acres (4.13 net developable acres) at 4730 140th Street NE. History In June 2023, the Planning Commission reviewed a conceptual site plan and approved Resolution 23-05PC to allow for the developer to apply for a PUD under criteria found in Section 1132.801 for a project less than 10 acres. On July 22, 2024, KJ Walk Inc submitted an application to develop the subject property as a single-family development. After initial city review, the city identified critical items that needed further study and revisions. As part of this process, the city, with developer consent, has extended the hearing and decision deadline, per MN SS 15.99, on four occasions. This process has led to numerous revisions and modifications. Staff is now confident the applicant can meet the standards of the city and should pro- ceed with their application. PRELIMINARY PLAT AND PRELIMINARY PLANNED UNIT DEVELOPMENT PLAN The subject parcel is 5.38 acres with 4.13 acres developable for residential homes. Topography, wetland locations and minimum density requirements require lot size var- iations that are not conducive to standard low-density R-1 lots. Therefore, a Planned Unit Development is proposed for this development to both minimize development im- pact while maintaining a minimum density of 2.5 units per acre. PHYSICAL SITE CHARACTERISTICS: Total Site Area: The total development site area is approximately 5.38 acres. Net acreage for development is approximately 4.13 acres. 2 Topography: The area includes upland around 900’ MSL elevation with moderate un- dulation with a high point near 924’ MSL. There are lower wetlands near 898’ MSL. Wetlands: There are wetlands located throughout the property. The unique lot design, layout and unit types take this fact into consideration. The developer proposes mini- mizing impact on the wetland through design. These designs are evaluated under the regulations of the Wetland Conservation Act. Access: The primary access to this site is at the intersection of Bluebird Trail NE and Rolling Oaks Circle NE. Rolling Oaks Circle NE connects to CSAH 42. Bluebird Trail NE was designed and intended to continue from its current terminus to Rolling Oaks Circle NE. 2040 Comprehensive Plan: This property is guided for Residential Low Density in the Comprehensive Plan and the development proposal matches this designation. Zoning: The subject parcel is zoned R-1, Low Density Residential. The density pro- posed by this development matches the requirements of the R-1 zoning. PROPOSED PLAN Lots: The development plan calls for 11 new residential lots. These lots vary in size from a minimum width of 65 feet to a maximum width of 97.83 feet. Single-Family Units The lots will range from 8,439 to 28,000+ square feet. Front yard setbacks will be 25 feet with side yard setbacks of 7.5 feet. Minimum rear yards will be 20 feet. Density: Density of the development is based on the net area of the site, which is approximately 4.13 acres. At 11 units this calculates to 2.67 units per acre. This is consistent with R-1 zoning and LD-R land use standards which have a minimum 2.5 unit per acre requirement. This density is substantially similar to the adjacent subdivi- sions. Building Setbacks: The developer is proposing the following standards as part of the R-1, Low Density Residential Planned Unit Development: Setbacks R-1 Proposed Lots Front 25’ 25’ Side 10’ 7.5’ Rear 25’ 20’ Side yard (abutting street) 25’ 25’ Min. Lot Width 86’ 65’ Min. Lot Depth 140’ 120’ Min. Lot Size 12,000 sf 8,439 sf Sidewalk/Trails: A sidewalk is provided on south side of Bluebird Trail NE and matches alignment with the existing path. Tree Replacement: The applicant submitted a tree survey identifying a total of 312 trees on the site, of which 290 trees (3,586” DBH) qualify as significant under the 3 City’s ordinance. The development proposes to remove 216 trees, including 199 sig- nificant trees totaling 2,506” DBH. Per the Zoning Code, up to 35% of significant tree inches (≈1,255” DBH in this case) may be removed without replacement. The proposed removals exceed this allowance by approximately 1,251” DBH. Using the required replacement ratio of ½ caliper inch per inch removed in excess, the project generates a replacement obligation of 625 caliper inches. One heritage tree (a 31” Red Oak in good condition) is being preserved. In accordance with ordinance provisions, this tree provides a credit of 62 caliper inches toward the replacement requirement. After applying this credit, the net tree replacement obligation is 563 caliper inches. For context, this replacement obligation equates to: • 281 trees at 2” caliper; or • 225 trees at 2.5” caliper; or • 188 trees at 3” caliper. The developer submitted an existing tree plan and will submit a Tree Replacement Plan at the time of Final Plat that demonstrates how this requirement will be satisfied. At least 80% of replacement must be provided through overstory trees unless other- wise approved by the Zoning Administrator. Replacement trees shall be planted on private lots within the development unless the applicant demonstrates it is not feasible, in which case the ordinance allows off-site planting or fee-in-lieu contributions as alter- natives. Streets: The proposed project will have local public streets that will be 28’ curb to curb. This design matches the existing Bluebird Trail NE connection. There will be 55’ Right- of-Way (ROW). All public streets will be constructed to the City of Prior Lake Engineer- ing and Public Works Standards. Sanitary Sewer / Water Mains: Sanitary sewer and watermains will be extended through Bluebird Trail NE. Grading / Storm Water: The site features modest changes in grading. The proposal is to grade the development in one phase to take place in Spring 2026. The site will be graded so that storm water drainage will be directed to one storm water basin in the north and one on the southwest portion of the site. This will hold volume until water is discharged to the wetland. Fees and Assessments: Development fees will be subject to the standards of the city as required by the fee schedule. Additional fees or escrows may be collected for de- velopment related activities. Easements and Walls: A conservation easement will be placed over a significant por- tion of property located near CSAH 42. This will be dedicated to the Prior Lake - Spring Lake Watershed District. Two walls will be located in Outlot A and built to city design standards for walls on public property. Walls located on private property for public pur- pose will be the responsibility of the homeowner and a legal instrument shall be rec- orded against the property for that purpose. 4 Additional easements will be required for public infrastructure on Lot 8, Block 1 of Eagle Ridges Acres (PIN 250520092). PLANNED UNIT DEVELOPMENT: Exceptions: The site is encumbered by significant wetlands and existing road connec- tions. The Metropolitan Council limits development access to sanitary sewer to those developments 2.5 units per acre or greater based on the City’s Comprehensive Plan. Without this PUD, development on this site is impractical. Lot size reductions, setback reductions and lot width reductions are requested by the developer. Public Benefit: The project, as proposed, through establishment of a conservation easement, placement of stormwater basins to protect wetlands, and minimizing tree removal where feasible will provide for continued protection of sensitive wetlands and conservation of wildlife in addition to the improvement of trails, and roads. Tree removal was minimized and wetlands related to those trees preserved. The connection of Blue- bird Trail to Rolling Oaks will eliminate a current ±1,500 ft. dead end road. Conclusion City staff and the developer met and communicated on several occasions as the de- veloper has worked through multiple plan revisions based on city and Prior Lake-Spring Lake Watershed District (PLSLWD) comments. City staff is recommending approval of the preliminary plat and preliminary PUD plan requests, subject to a condition that the developer revise plans to address all City com- ments. ALTERNATIVES: 1.

Luke Warren Israelson Registration #: 51362 STONE PATH PRIOR LAKE, MN GENERAL PROJECT INFORMATION: RESPONSIBLE PARTIES: The Contractor and Owner must apply for coverage under the MPCA's General Storm Water Permit for Construction Activity as required by the National Pollutant Discharge Elimination System (NPDES) Phase II program. Coverage under the permit will begin automatically 7 calendar days after the postmarked date on the permit application. [Longer time frames apply to sites that: (1) disturb areas greater than 50 acres AND discharge within 1 mile of a Special or Impaired Water; or (2) Use alternative storm water treatment techniques]. Owner: KJ Walk, Inc. Luke Israelson Contact Person Phone SWPPP Preparer: KJ Walk, Inc. Luke Israelson Contact Person Phone Contractor: KJ Walk, Inc. Luke Israelson Contact Person Phone Person Responsible For Inspections: KJ Walk, Inc. Steven Gisch / Rubens DeMello Contact Person Phone Party Responsible for Long Term O&M of Permanent Storm Water Management Facility: City of Prior Lake <952.447.9800> PROJECT LOCATION: County, State Scott, MN PROJECT DESCRIPTION: This project includes disturbance of approximately 4 acres. Construction activities include tree clearing, Soils on the site are primarily of Hydrologic Soil Group Type D, with low infiltration capacity. Planned Construction Start Date: Estimated Construction Completion Date: PROJECT AREAS: Total Project Size (disturbed area) = Existing area of impervious surface = Post construction area of impervious surface = Total new impervious surface area created = STORM WATER MANAGEMENT: Type of storm water management used if more than 1 acre of new impervious surface is created: Wet sedimentation basin Infiltration Filtration Required Water Quality Volume: Design Water Quality Volume: Elevation of Water Quality Volume Storage: Surface Area at Water Quality Volume Storage: Allowable Discharge of Water Quality Volume: Designed Discharge for Water Quality Volume: Required Infiltration Volume: Designed Infiltration Volume: Township Range Regional pond Permanent storm water management not required Section(s) Latitude Alternative methods <952.222.4419> Longitude RECEIVING WATERS: Surface waters which will receive storm water from the site within 1 mile of project boundary. Include waters shown on USGS 7.5 minute quad and all waters identified in Appendix A of the permit. Name of Water Body Impairment: CONSTRUCTION ACTIVITY NOTES: EROSION PREVENTION PRACTICES: Phased construction will be used to extent practical or as indicated in the plans to minimize exposed soils. Areas not to be disturbed shall be delineated with flags, stakes, signs, silt fence, etc. prior to work beginning. The normal wetted perimeter of all ditches or swales, including storm water management pond slopes, that drain waters from the site must be stabilized within 200' of any property edge or discharge point, including storm sewer inlets, within 24 hours of connection. Energy dissipation or other outlet treatment must be installed within 24 hours of connection. All exposed soils must be stabilized as soon as possible but in no case later than 7 days after the construction activity has temporarily or permanently ceased. Seed and/or sod, fertilizer, and mulch shall be placed as indicated in the plans and project specifications. Rapid stabilization shall be of type and quantity indicated in the project specifications. Additional rapid stabilization may be necessary to minimize erosion throughout the duration of the project. Type and quantity shall be determined by the engineer or inspector prior to installation. If the Contractor stockpiles material on site, he shall install the appropriate erosion control devices around the stockpile and perform the best management practices possible to avoid erosion from the stockpile. Temporary (or permanent) sedimentation ponds are required for areas > 10 acres of disturbed soils draining to one point. SEDIMENT CONTROL PRACTICES: Installation of silt fence and all other down gradient sediment protection measures shall be completed prior to commencement of upstream land disturbing activities. Silt fence shall be installed along constant contours with continuous lengths not to exceed 600 feet. As indicated on plans, silt fence will be periodically broken and hooked upslope in "J-hook" or "smile" patterns to provide ponding and slow runoff. No unbroken slope lengths greater than 75 feet are permitted when slope is 3:1 or greater. Slope shall be broken with silt fence or biorolls as indicated on plans. Vehicle tracking to be minimized to all practical extents. All eroded material that leaves the construction zone shall be collected by the contractor and returned to the site at the contractor's expense. All stock piles shall be surrounded by silt fence and seeded with temporary seed and mulch. See erosion and sediment control plans. All site storm sewer inlets, as well as off site downstream inlets with potential to receive sediment, shall be protected with approved inlet protection measures at all times. Inlets shall remain protected until site is 100% stabilized and vegetation is at least 70% established. Inlet protection may be removed in winter, if the project has an approval letter from jurisdictional authority or can produce it within 72 hours. TEMPORARY SEDIMENTATION BASINS & DEWATERING: Temporary sedimentation basins are required prior to runoff leaving the construction site or entering surface waters when 10 or more acres of disturbed soils drain to a common location. The basin must provide 3,600 cubic feet of storage below the outlet per acre drained. If hydraulic calculations are available, the temporary sedimentation basin must provide a storage volume equivalent to the 2-year, 24-hour storm, but in no case less than 1800 cubic feet per acre drained. The temporary sedimentation basin must be constructed and made operational concurrent with the start of soil distrubance upgradient of the pond. BMP Type (ditch, pond, wetland, lake, etc.) Appendix A Special Water? Flows to Impaired Water within 1 mile? QUANTITY USEPA Approved TMDL? All dewatering on site during construction must be routed to temporary sedimentation basins. Temporary sedimentation basins must be drained within 48 hours of any rainfall event. If the rock filtered outlets plug or cause the pond not to drain within 48 hours, ponds are to be drained with pumps. Pump inlets should be protected with a geotextile membrane and rock filter setup as shown in the details, or an approved alternative. Excessive sediment-laden water that is not properly filtered will not be permitted to discharge from site. Dewatering practices cannot cause downstream nuisance conditions, erosion, or non-permitted wetland inundation causing adverse impacts. POLLUTION PREVENTION: All solid waste collected from the construction site must be disposed of in accordance with MPCA disposal requirements. Concrete washout must be contained in a dedicated area surrounded by silt fence with proper signage All hazardous materials (e.g., oil, gasoline, fuel, antifreeze, paint, cleaning solvents, curing compounds, fertilizers, etc.) must be properly stored (including secondary containment when necessary) to prevent spills, leaks, or other discharge. Storage and disposal of hazardous waste must be in compliance with MPCA regulations. External washing areas must be limited to a defined area of the site. All runoff containing any hazardous material must be properly collected and disposed of. Defined area must be contained with heavy- or super-duty silt fence. NO ENGINE DEGREASING ALLOWED ON SITE. The contractor is responsible for monitoring air pollution and ensuring it does not exceed levels set by local, state, or federal regulations. This includes dust created by work being performed on the site. Air pollution and dust control correction is considered incidental to the unit bid prices for which work is being performed. Additional dust control measures may be required by the Engineer. INSPECTION & MAINTENANCE: The permittees must routinely inspect the construction site once every seven (7) days during active construction and within 24 hours of a rainfall event greater than 0.5 inches in a 24 hour period. All inspections performed during construction must be recorded and records retained on site with the SWPPP in accordance with the storm water permit. Records must include a site map showing areas of land disturbing activities and areas where activities have temporarily or permanently ceased. Silt fence, biorolls and inlet protection devices must be maintained when non-functional or when accumulated sediment reaches 1/3 of device height.

The following documents were reviewed: • Civil Plan Set – Stone Path Plans 20250829.pdf • Drainage Report – SP Stormwater Report 20250827.pdf Comments are provided within this Memorandum and in the corresponding redlined plan set. Please note that not all comments within the plan set are in the Memorandum. We have the following comments with regards to stormwater management and engineering. Greyed out comments have been addressed. General 1. Submit for and provide copies to the City of all required permits from regulatory agencies (MCES, Minnesota Pollution Control Agency, Minnesota Department of Health, NPDES, etc.) 2. An NPDES permit is required for this site as it exceeds 1 acre of disturbance. 3. Additional comments may be generated by PLSLWD’s review of the revised plans 4. Additional redline comments are provided in the accompanying plan set. Provide a response to all comments in this memo and the redlined plan set. Grading Plan 1. Divert common drainage down property lines. 2. Call out roadway high point 3. Clarify drainage on the west side of Lot 1 Block 2 a. Provide additional proposed and existing spot elevations as well as flow arrows on Lot 1 and the existing lot to the west to ensure water flows down the lot line. 4. Step Lot 2 Block 1 down between Lots 1 & 3 (1.0’) so the transition between 1 & 2 (1.5’) is not as severe (2.5’) 5. Raise the Lot 7 Block 2 FFE and EOF 0.5’ to get the EOF route to the street a. Reroute storm sewer CB to street b. Eliminates Lot 7 Block 2 driveway culvert c. Maintain maximum 4:1 slopes between lots 6. Provide additional easement on Lots 6 & 7 Block 2 for drainage from one lot to another a. Direct water on the east side of Lot 7 Block 2 to the north away from the building pad 7. Divert common drainage down Block 2 property lines 8. Show all proposed retaining walls. 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. Provide top and bottom of wall elevations. Provide a fence for walls greater than 4’. The retaining wall for Lot 1 Block 1 shall be out of the wetland buffer area and drainage and utility easements. a. Provide additional details for the retaining wall west of Lot 1 Block 2. b. Keep retaining wall completely on Lot 1 Block 2 c. Coordinate permanent transitional grading on adjacent existing lot d. Provide future ownership and maintenance of all retaining walls (if applicable). 9. Revise the HWLs to match the HydroCAD model. 10. Identify wetland buffer 11. Specify access routes to and along the ponds from the roads that meet slope and width requirements, are within drainage and utility easements, and are outside of the wetland buffer. a. The slope and width requirements are a maximum grade of 8%, maximum cross slope of 2%, and a minimum width of 10’. 12. Show house style detail drawing. 13. A minimum of 10 feet beyond the house pad shall have a slope less than 10:1 unless otherwise approved by the City Engineer. a. Review and revise the grades adjacent to Block 1 Lot 1 as the retaining wall and steep slopes are within 10-feet of the proposed home. Utilities 1. Storm Sewer a. Change CB1-5 to a 4’ deep sump. b. Pipe class shall conform to design standards as shown in the American Concrete Pipe Association LRFD Fill Height Tables. Review the pipe class for the following pipe: i. OS2-2 to FE2-1 c. Add the MnDOT standard rip rap detail to the plans. d. Provide an inlet capacity analysis. The catch basins on the roadway should not receive more than 3 cfs in the 10-year event. e. Insulate when the separation between the storm sewer and water is less than 36" f. The discharge velocity into Pond A and Pond B exceeds 6 fps. Modify the slopes of the incoming pipes to reduce the velocity below 6 fps. g. Please provide calculations for the sizing of the pipe from FES3-2 to FES3-1. h. Match the flared end section elevations to the pond outlet elevation. 2. Sanitary Sewer a. Show assumed service riser lengths b. Reverse flow direction of existing sanitary sewer main 3. Water a. Coordinate the watermain connection to Rolling Oaks Trail with City staff. i. Provide a proposed traffic control plan to City for review. ii. Staff will need to provide notification to residents 48 hours prior to construction. b. Maintain minimum 10’ horizontal separation from sewer c. Maintain minimum 18” vertical separation from storm sewer with water services i. Insulate when the separation between the storm sewer and water service is less than 36" Streets/Trails 1. Verify size of vertical curves meet minimum City requirements a. Provide stop ahead or reduced speed signs as required. b. Minimum sag value is 36. 2. At intersections, the street grade shall not exceed 2.00% for the first 100’ approaching said intersection. The 100’ is measured from the curb line of the intersected street. a. In cul-de-sacs, the gutter grade shall not be less than 0.80%. Stormwater Management 1. Rate Control a. This site is in Prior Lake’s Stormwater Management Overlay District #1. Rate control for the 2 and 10-year events cannot increase from the existing runoff while the peak runoff for the 100-year event must be held to 0.25 cfs per acre. i. Please provide calculations or list of HydroCAD nodes for how it was determined that 37.68 cfs of existing offsite flow pass through the site in the SWMP. We were not able to reproduce that number. ii. Please provide a figure showing the 4.64 acres subjected to restricted rate control. Ensure it includes the entire developed area. iii. The west and north discharge points go in different directions and should not be lumped together. Rates to the west are met. Proposed rates to the north (38.9 cfs) exceed the allowable (38.7 cfs). b. Maintain the approved discharge rate from Rolling Oaks Circle BMP with the removal of the basin. i. How is the discharge rate from Rolling Oaks Circle BMP being maintained? Detail in the SWMP. c. The wetland is used for rate control. Provide bounce and inundation analyses for the wetlands based on their management class. i. Show that the wetland meets the stormwater treatment and hydrologic guidelines of Table 1.1, MnRam Version 3.0. 1. Please add the analysis of Table 1.1 to the SWMP. 2. Volume Control a. Provide an analysis of the existing treatment provided by the Rolling Oaks Circle BMP and how that treatment volume is maintained in proposed conditions, treating both the existing road and proposed homes. i. We understand that the focus is on treating site water. However, the existing BMP off Rolling Oaks Circle was designed in 2017 to treat the roadway impervious. Ensure that the treatment removed will be replaced in Pond B. 3. Low Floor/Low Openings a. Low opening elevations shall be at least 2’ above the emergency overflow (EOF). i. Lot 4 Block 1 has a low opening of 903.5’, EOF of Pond B is 901.55’. 1. Call out Lot 4 Block 1 as a WO/LO with a REQUIRED elevation on the northeast rear corner of minimum 903.55 to meet the requirement with the EOF of the pond. b. Low floor shall be at least 2’ above the HWL. i. Lot 4 Block 1 has a low floor of 903.5’. The HWL of Pond B is 901.81’. c. Ensure that the newly created low point in the southwest corner of Rolling Oaks Circle and Bluebird Trail does not have a high water level that will impact the adjacent homes. d. Please add the low floor and low openings of the existing home west of Pond A to the plans and ensure freeboard is met. i. The LO of the existing home is at 886.1 ft and the HWL of the wetland is at 884.15. Please provide 2-feet of freeboard between the low floor and the 100- year HWL of the existing home. 4. Water Quality a. Include snips of the MIDS inputs or provide the MIDS models so the devices can be reviewed. Provide justification for use of street sweeping. i. Update surface area at overflow in MIDS for Pond A to match the HydroCAD model (or vise versa, whichever is correct with the grading plan). ii. Update the inputs for Pond B to match the latest plans. iii. Remove street sweeping from the MIDS model. iv. Provide a reference to where the sump structure removal percentages were obtained in the SWMP (utilize calculations for these specific sumps, not percentages from past projects). 5. Basin Design a. The HWL is not contained within Pond A. Rules state that the EOF of a basin should be 1 foot higher than the HWL. b. The HWL is not contained within Pond B. Rules state that the EOF of a basin should be 1 foot higher than the HWL. c. Add a 48 hour drawdown analysis to the drainage report for the biofiltration basin. d. Add details for OCS 1 and OCS 2 that show the weir wall. e. Pond berm design requirements are not met. i. The top of the berm shall be 2 feet above the 100-year HWL. ii. The berms should have a maximum of 4:1 side slopes. iii. The top of the berm shall be at least 10’ wide at the top. f. The bottom of Pond C is covered with rip rap. How will it function as a biofiltration basin as stated in the plans and model? 6. Hydraulic/Hydrologic Analysis a. Include all offsite drainage for the purpose of determining the high water level in Pond B and the wetland. i. Offsite drainage is missing west of the wetland, north of Blue Bird Trail. b. The storage modeled in HydroCAD for Pond B is about half of what is available per the grading plan. c. Expand the drainage area extents or include secondary figures that show the entire drainage area to the site. d. The modeled outlet pipe slopes for Basin A and Basin B do not match the plans. SWPPP 1. Include documentation of training in the SWPPP. 2. Add erosion control symbology to the legend. a. In addition to silt fence and inlet protection, add the rock construction entrance to the legend. 3. Show perimeter control around Pond A and Pond B to protect the filtration area. 4. Show inlet protection on all catch basins on and adjacent to the project site. 5. Include a permanent restoration plan. a. What seed types will be used to stabilize? Ensure an adequate mix is used within the wetland buffer area. i. MnDOT Southern Boulevard seed mix is not a native mix. Please do not use in the wetland buffer area. 6. Indicate the soil stockpile area if applicable. 7. Include a map of all surface waters, existing wetlands, and stormwater basins which can be identified on a map within a 1 mile aerial radius that will receive stormwater from the construction site. Identify if the surface water is a special or impaired waterbody. Wetland 1. A wetland delineation has been completed and was approved by the City (NOD March 1, 2024). Plans must be updated to reflect approved boundaries. 2. Based on locations of approved wetlands, permanent impacts will occur as a result of construction. A wetland permit through the WCA must be obtained prior to construction. 3. Impacts to the tributary (non-wetlands) may require a Section 404 permit through US Army Corps of Engineers. 4. Show on the plans wetland and watercourse buffers that comply with Rule J of the PLSLWD rules. Include measurements of minimum and average buffer widths. 5. Disturbed areas within the buffer should be revegetated with a native, weed-free, seed mix. Tree Preservation & Replacement / Landscaping 1. Tree replacement plan to be submitted to meet City Code requirements. 2. Developer is encouraged to meet with property owner at 14030 Rolling Oaks Cir. NE to determine if additional screening or plantings are desired by the property owner. Placement of trees and screening at 14030 Rolling Oaks Cir. will count toward the required tree replacement for Stone Path. Easements 1. Conservation easement required with Prior Lake – Spring Lake Watershed District. 2. Retaining wall easement(s) required for retaining walls on private property. 3. Easements required for public infrastructure on Lot 8, Block 1, Eagle Creek Ridges Acres. 4. Temporary construction easements required on Lot 9, Block 1 and Lot 1, Block 2, Maple Hill 2nd Addition. PLSLWD 1. Additional comments have been generated by PLSLWD’s review of the revised plans Scott County 1. Scott County comments have been added to the plan sheet.

FREESE ANTHONY J. WINIECKI, P.E. Transportation Services Director County Engineer An Equal Opportunity/Safety Aware Employer September 17, 2025 Paul Moretto City of Prior Lake 4646 Dakota Street SE Prior Lake, MN 55372 SUBJECT: Stone Path Preliminary Plat Dear Paul, Thank you for the opportunity to review the preliminary plat for Stone Path. We have reviewed and offer the following comments: • The County agrees with what is being proposed for right of way dedication along CH 42. However, the stomwater pipe running parallel in the County right of way and the proposed ponding in the right of way for CH 42 will not be permitted. • The existing driveway access to CH 42 shall be required to be fully removed from the County right of way and graded to match the existing ditch. • Detailed Stomwater information shall be required to be submitted to the County for review and approval. • No ponding, berming, signage, or landscaping shall be permitted in the county right of way. • Any work within the County right of way shall require a County permit. If you have any questions or need further information, please contact me. Sincerely, Craig Jenson Transportation Planning Manager Memorandum To: Stephanie Thulien, Water Resources Engineer From: Troy Kuphal, Scott SWCD Director Cc: Joni Giese, PLSLWD Administrator Luke Schwartz, Assistant City Engineer Laura Pietila, Project Engineer Kris Keller, Project Engineer Date: September 17, 2025 Subject: Stone Path Preliminary Plat Review Thank you for the opportunity to provide review comments on the September 3rd submittal for the subject project. The District’s Engineer completed their review of the civil plans dated 8/29/2025 and stormwater report dated 8/27/2025 and offers the following comments. Please note previously submitted comments that haven’t fully been addressed are included in black text, and new comments are included in blue text. Rule D – Stormwater Management 1. Submit filtration basin construction sequencing demonstrating appropriate phasing and/or protection of filtration media from clogging until tributary drainage areas are stabilized and vegetated. 2. Total impervious in the proposed hydroCAD model is less than the house pad sizes shown on the plan set. Modeling should assume the maximum allowable impervious per lot to cover future hardscaping by homeowners (sheds, patios, etc). 3. The internal weirs in the Pond A & B outlet structures (and the wetland weir wall) are modeled as custom weirs/orifices in hydroCAD. This approach is atypical and may have an impact on peak flow rates. Rule F – Floodplain Alteration 1. There is floodplain filling on Lot 1, Block 1 below the existing 100-yr HWL for the wetland. Compensatory storage should be provided and may address the issue of freeboard for the existing home to the west of the wetland. Rule J – Buffer Strips 1. The owner will be required to enter into a Developers Agreement with the District (via the SWCD) for establishment of and record a conservation easement over required buffer strips. The conservation easement shall be over the buffer area(s) only. 2. Buffer strips are required around all onsite wetlands and must have an average width of at least 30 feet and a minimum width of at least 15 feet. 3. Details for buffer monumentation and vegetation establishment are detailed in Rule J Paragraphs 7 and 8, respectively, and must be incorporated into the construction or landscape plans. 4. Legal descriptions, and AutoCAD Civil 3D layers for proposed buffers and wetland boundaries will be required for review and acceptance conservation easement boundary.
