LEVEL OF CITY DISCRETION IN DECISION-MAKING: The city’s discretion in approving or denying a Site Plan is limited to whether or not the proposed project complies with Zoning Ordinance requirements. If it meets these standards, the city must then approve the site plan. This is a quasi-judicial decision. Notice of this public hearing has been mailed to all property owners within 500 feet. PROPOSAL/SUMMARY The developer is requesting site plan approval for a 33,283 square-foot building for the use of an office and a light industrial warehouse that would be used in part by Affinitech, Inc. Affinitech is an existing business in Chanhassen providing professional audio and video systems. They are currently located at 1264 Park Rd. The proposed building would allow for their business expansion. APPLICABLE REGULATIONS Chapter 20, Article II, Division 6, Site Plan Review Chanhassen West Business Park – Planned Unit Development Regulations BACKGROUND The City of Chanhassen and Volk-Minger Properties, LLC, a Minnesota limited liability company, entered into a development contract for Chanhassen West Business Park dated October 10, 2005, recorded October 13, 2005, as Carver County document No.A426223; was amended by Addendum “A” to the Chanhassen West Business Park development contract dated November 16, 2005, recorded November 28, 2005, as Carver County document No.A429887; and also amended by Addendum “B” to the Chanhassen West Business Park development contract dated August 14, 2006, recorded September 13, 2006, as Carver County document No.A449656. 6 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 3 of 9 Environmental Protection Districts · Bluff Creek corridor - This parcel is not encumbered by the Bluff Creek Overlay District. · Bluff Protection - There are no bluffs on the property. · Floodplain Overlay - This property is not within a floodplain. · Shoreland Management - The property is not located within a shoreland protection district. · Wetland Protection - There is not a wetland located on the development site. Site Plan Review The developer is requesting site plan approval for a 33,283-square-foot building. Approximately 17,754 square feet will be used as office space and 20,056 square feet will be used for light industrial/warehousing. Architectural Compliance Materials and Color The site is located in the Chanhassen West Business Park, which does establish requirements for building materials and design. The material finishes on the structure include precast concrete painted panels, exposed aggregate precast concrete panels, aluminum window/door frames, architectural metal coping, and composite wood. The colors of these materials will be light gray, dark steel, cobalt blue, and medium brown wood. The design provides architectural relief on the front façade by staggering walls to break the plane. Entryway projections are used as architectural treatments to provide interest. All building elevations potentially visible from the public right-of-way are highly developed to ensure visual quality. 7 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 4 of 9 Building Size, Placement, and Lot Coverage The Chanhassen West Business Park requires a minimum front setback of 30 feet, the building is placed on the plans 79.4 feet from the front property line. The site has a minimum setback of zero feet, the plans show 49.3 feet and 58.5 feet. The minimum rear setback is zero feet, and the plans show 104 feet. The setbacks are as determined by the street and interior lot lines. The Planned Unit Development (PUD) limits the hard surface coverage to 70%, any lot can exceed the 70% requirement so long as the entire finished development does not exceed 70%. The site exceeds the per-site limit at 77.6%; however, the finished development will have a hard surface coverage of 62.6%. This is the last remaining site to be developed in the Chanhassen West Business Park. Height and Roof Design The building has a flat roof with parapets that reach a maximum of 34 feet with the highest points being the entrances. The proposed building’s height is within the maximum allowed of three stories or 40 feet, as established by the PUD. All roof equipment is fully screened by the parapet from 250 feet from the building towards the right-of-way. Lighting and Signage There is no proposed signage associated with this site plan review. All signage will be permitted and reviewed separately. Lighting has been proposed and photometrics have been provided along with the site plan. Four shoe box fixtures with square ornamental poles will be provided per the PUD standards. A total of 14 shielded wall lights will be installed. Light level at the property line does not exceed ½ foot-candle. Loading Areas and Refuse All loading areas on the proposed site plan are located in the rear of the property and are fully screened from the public right-of-way. No plans have been provided for refuse, if the refuse is to be stored outside the enclosure shall meet all building requirements. As a part of the building permit process, the Developer shall submit plans for city review and approval. 8 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 5 of 9 Parking Locations and Requirements The city code requires one parking space per 1,000 square feet of warehousing space and five parking spaces per 1,000 square feet of office space. The project is proposing 20,056 square feet of warehousing space, resulting in 20 required parking stalls. In addition, the project is proposing 17,754 square feet of office space resulting in 89 required parking stalls. In total, the site shall provide a minimum of 109 parking spaces. All parking is set back from the front property line the minimum 10 feet, as stipulated by the PUD. Parking located on the side and rear does not have a minimum setback from the property line. City code allows for flexibility in the number of parking stalls constructed at project inception if the Applicant indicates a parking need less than the minimum allowed; however, the Applicant must show through a proof of parking exhibit that the site as designed has the capability to support the total number of parking stalls required by city code in the event that parking becomes an issue and the additional parking must be constructed. The applicant has provided proof of parking exceeding the requirement at 117 parking spaces. Site Furnishings The Developer shall provide an area for bicycle parking and storage; this is not currently provided for on the plans but is a part of staff stipulations and comments. A sidewalk connection between the sidewalk within the public right-of-way to the building is provided on the NE side of the lot. Access No public streets are proposed as part of this project. The developer is proposing two full accesses to the site off Galpin Court, one from the north and one from the south sides of the lot. As the northeasterly access extends onto the adjacent lot (Lot 4, Block 2, Chanhassen West Business Park), it must either be relocated south to be wholly on the development’s lot (Lot 3, Block 2, Chanhassen West Business Park), or a private access agreement or cross-access easements will need to be obtained and recorded against the lots. Easements Public drainage and utility easements DUE were recorded with the Chanhassen West Business Park final plat along Lot 3, Block 2’s property lines. These include a 10-foot-wide DUE along all property lines other than a five-foot-wide DUE along the north and northwest property lines, which are standard widths associated with Chanhassen City Code. As discussed under the “Utilities” section of this report, the water main will be public and adequate DUE shall be recorded over the water main. 9 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 6 of 9 Utilities The site has access to public sanitary sewer and water main stubs abutting the property within Galpin Court right-of-way. These were installed in conjunction with the build-out of Galpin Court and the Chanhassen West Business Park development. The applicant proposes extending these existing sanitary sewers and water main stubs. The proposed water main extensions shall be owned and maintained by the city after acceptance of the public improvements by the City Council. As such the installation of these public utilities will be required to be constructed in conformance with the latest edition of the City of Chanhassen’s Standard Specifications and Detail Plates (Standards). In order to access and maintain the newly installed public utilities, adequate public drainage, and utilities (DUE) must be recorded prior to or concurrently with the site plan agreement. Minimum DUE are 20 feet wide from the center of the alignment in typical construction applications, however, easements can vary in width depending on the depth and size of infrastructure proposed. In order to determine appropriate easement widths, the applicant will be required to supply profile drawings of all the public utilities being extended on site. Profile drawings will also determine if any additional improvements may be necessary with the construction of the utilities (i.e., insulation, horizontal bends, material type, air relief valves, etc.). All hydrant locations must be verified by the Fire Department. Based on the plans provided, which are in general conformance with the Chanhassen West Business Park’s preliminary plat plans, the public water main will be looped internally as well as interconnecting to the west and southeast properties to provide better serviceability and water quality to the site(s). Final construction plans shall be updated to eliminate redundant water main valving to the maximum extent practicable. Sanitary sewer extended into the site will be privately owned and maintained in accordance with the Chanhassen City Code which demarcates the ownership between public and private at the right-of-way line. However, the sanitary improvements will also need to meet Standards up to, and including, the proposed sanitary manhole (SMH2 from the “Galpin Industrial Final” plans dated 11/2/2023) in order to protect the public system against infiltration and inflow. Final construction plans will be subject to review and approval by staff prior to recording the site plan agreement. The parent property associated with the Chanhassen West Business Park was assessed the trunk sanitary sewer and trunk watermain charges in 1994 in conjunction with City Project 91-17B, Upper Bluff Creek Sewer and Water. This assessment has been paid and in accordance with Addendum “B” to Chanhassen West Business Park’s Development Contract, Sewer and Water Hookup Fees are not due with the building permit. The Metropolitan Council Sanitary Access Charge (“MCES SAC”) is payable at the time of building permit issuance as required by the city’s Fee Schedule. The 2023 MCES SAC is $2,485 plus a $75 city surcharge. 10 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 7 of 9 Permits from the appropriate regulatory agencies will have to be obtained, including but not limited to the MPCA, NPDES, Minnesota Department of Health, Carver County and Watershed District. Landscaping Natural resources staff reviewed the proposed plan set and found it to be generally in conformance with the city code; however, some revisions are required to the plan set so that the proposed project adheres to the city code. Those revisions are outlined in the conditions found at the end of this report. RECOMMENDATION Staff recommends that the City Council adopt the Findings of Fact and Decision in approving the requested site plan subject to the following conditions and findings: 1. The Developer shall provide an area for bicycle parking and storage. Two upside-down U racks shall suffice. 2. The Developer shall update the development summary table on the civil plans to state the required number of parking spaces is 109. 3. The Developer shall either state the placement of the refuse collection being incorporated into the interior of the building or shall update the plans to include the placement of the refuse collection outside which shall have proper screening as required by city code. 4. The north access shall either be relocated south to be wholly on Lot 3, Block 2, Chanhassen West Business Park, in accordance with Chanhassen City Code, or a private access agreement or cross-access easement shall be recorded against Lot 4, Block 2, Chanhassen West Business Park, benefiting the development, prior to or concurrently with recording of the site plan agreement. 5. All newly constructed water mains shall be public water mains, owned and maintained by the city, after acceptance of the public improvements by the City Council. 6. All sanitary sewer and water main improvements on the site will be constructed in accordance with the latest edition of the City of Chanhassen’s Standard Specifications and Detail Plates. 7. The Developer shall record public drainage and utility easements over all public utilities prior to or concurrently with the site plan agreement. 8. The Developer and their Engineer shall work with city staff in amending the construction plans, dated November 2, 2023, prepared by Brady D. Busselman, PE with Sambatek., to 11 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 8 of 9 fully satisfy construction plan comments and concerns. Final construction plans will be subject to review and approval by staff prior to recording of the site plan agreement. 9. It is the Developer’s responsibility to ensure that permits are received from all other agencies with jurisdiction over the project (i.e., Carver County, Carver County WMO, Board of Water and Soil Resources, US Army Corps of Engineers, etc.) prior to the commencement of construction activities. 10. The tree survey shall include a delineation of existing canopy coverage on site which outlines all areas covered by tree canopy, including the Northeast side of the site. A canopy coverage percentage based off of current site conditions must be calculated. This percentage will be used to determine the minimum canopy coverage requirements- outlined in the City Code- and therefore, the number of trees that must be replanted. The survey shall be amended to also include the condition of all trees in the survey. The survey must also include an inventory of all trees 10 inches diameter at breast height (DBH) or more- the site was visited by the City Forester, and it appears not all trees 10 inches or more were included in the survey. 11. The Developer shall revise the landscape plan to diversify species according to city code which requires that no more than 10% of total trees to be planted be the same species, no genus will have more than 20% of total trees and no one tree family will have more than 30% of total trees. It is recommended to substitute Sienna Glenn Maple for an Autumn Blaze Maple. Overstory trees must account for no less than 75% of the total trees required. 12. In addition to the tree protection fencing being shown on the Tree Preservation Plan, it must also be shown on the grading plan. 13. Bufferyard planting calculations must be corrected based on width of the buffer and length of buffer areas on each side of the property. 14. It is the policy of the city to preserve natural woodland areas throughout the city and to retain as far as practical substantial tree stands, such as the mature oak trees on this site, which can be incorporated into the overall landscape plan. The existing plant material can also be counted toward the total buffer yard plant material requirement as well as canopy coverage requirements. 15. A building permit must be obtained before beginning any construction. 16. Building plans must be prepared and signed by design professionals licensed in the State of Minnesota. 12 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 9 of 9 17. Building plans must provide sufficient information to verify that proposed building meets all requirements of the Minnesota State Building Code, additional comments or requirements may be required after plan review. 18. The building is required to have automatic fire extinguishing systems. 19. Structure proximity to property lines (and other buildings) will have an impact on the code requirements for the proposed buildings, including but not limited to; allowable size, protected openings and fire-resistive construction. These requirements will be addressed when complete building and site plans are submitted. 20. Building plans must include a code analysis that contains the following information: Key Plan, Occupancy group, Type of construction, Allowable height and area, Fire sprinklers, Separated or non-separated, fire resistive elements (Ext walls, bearing walls - exterior or interior, Shaft, Incidental use), Occupant load, Exits required (Common path, Travel distance), Minimum plumbing fixture count. 21. Retaining walls (if present) more than four feet high, measured from the bottom of the footing to the top of the wall, must be designed by a professional engineer and a separate building permit must be obtained prior to construction. Retaining walls (if present) under four feet in height require a zoning permit. 22. Accessibility to be provided in accordance with Minnesota State Building Code Chapter 1341. 13 Memorandum To: Rachel Arsenault, Associate Planner From: Joe Seidl, Water Resources Engineer CC: Charles Howley, Public Works Director/City Engineer George Bender, Assistant City Engineer Manuel Jordan, Environmental Resource Specialist Charlie Burke, Public Works Operations Manager Date: 12/01/2023 Re: Affinitech, Inc. Site Plan Review (2451 Galpin Court) - City Planning Case No. 2023-22 DRAINAGE AND REGIONAL BMP Drainage on the existing undeveloped lot drains to the east to Galpin Court and to the south property boundary, both of which is picked up in existing storm sewer and discharged to an existing regional stormwater pond with a filtration shelf located on Outlot A of the Chanhassen West Business Park Plat. The site is part of the 2005 Chanhassen West Business Park PUD. In addition to the stormwater management provided by the regional basin, the PUD plans show two rain gardens planned for this lot and a third rain garden on the southern border of the lot. Approximately 2.19 acres of impervious were included for this lot on the PUD plans. There is no FEMA floodplain on the site. In the proposed condition, the majority of the drainage from the parking lot is proposed to be directed to one of four rain gardens proposed adjacent to the parking lot which outlet to the existing storm sewer trunkline running on the southern boundary of the parcel. Roof drainage and a small portion of the parking lot is picked up by storm sewer which directly connects into the same storm sewer trunkline. The stormwater infrastructure will continue to discharge water to the existing regional basin as it does in the current condition. As part of the site review staff researched the ownership of the regional BMP system. The BMP collects and treats stormwater from both private property and public ROW. The drainage from 14 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 2 of 6 the ROW makes up approximately 10% of the total drainage area compared to approximately 90% from private property. Outlot A is owned by Volk-Minger Properties LLC. The Chanhassen West Business Park Plat does not show drainage and utility easement over Outlot A which would be required for the city to maintain the regional BMP. Furthermore, 2005 Chanhassen West Business Park Project Plans and archived correspondence between the original developer and the Carver County Water Management Organization (CCWMO) outline that an owner’s association will be responsible for the operation and maintenance of the storm water management system onsite. The 2023 site plan submittal did not address the maintenance or ownership of the regional BMP. It is critical that the ownership and maintenance of the regional BMP be confirmed and memorialized in an agreement recorded against the property. The applicant shall work with City staff and the CCWMO to confirm the ownership of the regional BMP system and ensure that a plan is in place for its perpetual maintenance. 15 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 3 of 6 16 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 4 of 6 EROSION CONTROL The proposed development will impact one (1) acre of disturbance and will, therefore, be subject to the General Permit Authorization to Discharge Stormwater Associated with Construction Activity Under the National Pollution Discharge Elimination/State Disposal System (NPDES Construction Permit). The applicant has prepared and submitted a Surface Water Pollution Prevention Plan (SWPPP) to the city for review. The SWPPP is a required submittal element for final site plan review along with the Erosion and Sediment Control Plan (ESCP) in accordance with Section 19-145 of City Ordinance. No earth disturbing activities may occur until an approved SWPPP is developed. This SWPPP shall be a standalone document consistent with the NPDES Construction Permit and shall contain all required elements of the permit. The SWPPP will need to be updated as the plans are finalized, when the contractor and their sub-contractors are identified and as other conditions change. All erosion control shall be installed and inspected prior to initiation of site grading activities. STORM WATER MANAGEMENT Article VII, Chapter 19 of City Code describes the required storm water management development standards. Section 19-141 states that “these development standards shall be reflected in plans prepared by developers and/or project proposers in the design and layout of site plans, subdivisions and water management features.” These standards include abstraction of runoff and water quality treatment resulting in the removal of 90% total suspended solids (TSS) and 60% total phosphorous (TP). The proposed development is located within the Carver County Water Management Organization (CCWMO) and is therefore subject to the CCWMO’s rules and regulations. A Stormwater Management Report dated November 17, 2023 was submitted by the applicant to the City and provided to the CCWMO concurrently as part of the site plan review. Comments provided by the CCWMO must be addressed and a permit from CCWMO is required prior to construction. The site is within CCWMO and is required to meet all applicable WMO rules which includes volume abstraction of 1 inch of runoff from all new or fully reconstructed impervious. A geotechnical report was submitted dated July 12, 2023, which included one soil boring onsite that showed sandy clays onsite and no groundwater present. Based on the soil borings the applicant noted this is a restricted site and that infiltration is not achievable onsite. The site is proposing meeting water quality requirements through use of the existing regional pond and filter bench and the four proposed rain gardens. The outlet control structure of the existing regional BMP is proposed to be modified to increase the water quality treatment within the pond. The rain gardens are proposed to be constructed with amended soil media and drainage due to the restrictive soils onsite. MIDS modeling was provided to demonstrate the 2005 PUD planned treatment and the 2023 proposed development treatment. While the modeling shows the site is proposing to provide more treatment than the 2005 PUD plan, the site is not in compliance with the City’s water quality treatment regulations which require 90% TSS and 60% TP removal efficiencies. 17 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 5 of 6 Currently the site is meeting the TSS removal requirement but is only providing a 59% TP removal efficiency. However, there are comments on the MIDS modeling which need to be addressed to confirm the removal efficiencies stated in the Stormwater Management Report. Additionally, the applicant assumed the regional BMP is at an as-built condition for water quality modeling. A survey is needed to confirm the current condition of the BMP to accurately calculate removal efficiencies. It is possible a pond cleanout project is needed to ensure that the stormwater system is functioning as designed. With the final design the applicant shall confirm the City’s water quality requirements are met once the modeling updates and other plan changes have been made. The Stormwater Management Report and supporting Hydrologic and Hydraulic HydroCAD model was reviewed. A HydroCAD model for the PUD site with the proposed conditions was provided. Because the PUD was developed prior to Atlas 14 conditions and would have been utilizing TP 40 rainfall data, a HydroCAD model showing the planned PUD site with Atlas 14 conditions prior to the proposed modifications (OCS modification, rain garden additions, etc.) shall be submitted to compare the proposed stormwater infrastructure modifications to what was approved with the PUD when looking at Atlas 14 conditions. These HydroCAD models will be used to confirm the site is meeting overall rate control requirements. The applicant shall provide final versions of all modeling (HydroCAD and MIDS) and SWMP report to address remaining comments and confirm rate control and water quality requirements are being met as part of the final site plan approval. As outlined in the City’s Surface Water Management Plan adopted in December 2018, the city requires at least 3 feet of freeboard between a building elevation and adjacent ponding features. The HydroCAD modeling shows the proposed HWLs with Atlas 14 rainfall events, which are higher than the HWLs noted on the PUD plan since those were based on TP 40 rainfall events. All existing and proposed buildings appear to be in compliance with the City’s three-foot freeboard requirement with respect to the Atlas 14 HWL 949.88. Even though the building on Lot 4 has an FFE (951) less than three feet above the Atlas 14 HWL, the pond does not present a flooding risk to the building due to the berm between the building and the pond graded up to a 952.0 elevation, which is 2.7 feet higher than the pond EOF. Additionally, the building on Lot 4 is located at a distance where groundwater impacts are not anticipated especially considering the clay soils observed in the soil borings. It does appear that water from the pond could back up into the existing storm sewer and surcharge through the existing CBMH on Lot 4 which has a rim elevation at 949.6, which could present a small risk to the existing building on Lot 4. It is unclear if this is an effect of utilizing Atlas 14 rainfall conditions or if it is a combined effect of Atlas 14 rainfall depths and the proposed modification to the existing regional basin BMP. The final BMP configuration shall be analyzed to confirm the proposed modifications do not create adverse impacts to the existing lots. The proposed BMPs are to be privately owned and therefore will require an Operations and Maintenance (O&M) Agreement and associated plan. The plan will need to identify the maintenance schedule, responsible party, and shall include information on how the system will 18 Todd Brown – Affinitech Planning Case 2023-22 December 5, 2023 Page 6 of 6 be cleaned. The proposed private BMPs are to be located outside of drainage and utility easements. WATER RESOURCES RECOMMENDATIONS: 1. The applicant shall provide a copy of conditional approval from the CCWMO as part of any future construction plan submittals. 2. The applicant shall update the models (HydroCAD and MIDS) per City any CCWMO comments and submit updated computations and models in their native forms with the final site plan and final construction plans. a. An additional HydroCAD model for the PUD plans utilizing Atlas 14 conditions and discharge rate analysis shall be included in future submittals. b. The applicant shall confirm the 90% and 60% removals of TSS and TP are being met with future plan submittals. 3. The applicant shall confirm the proposed stormwater design will not adversely impact adjacent and/or downstream properties and water resources. 4. The applicant shall enter into an Operations and Maintenance Agreement for any proposed privately owned stormwater facilities prior or concurrently to recording of the site plan agreement. 5. The applicant shall work with City staff and the CCWMO to confirm the ownership of the regional BMP and ensure that a plan is in place for its perpetual maintenance. 19 CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION IN RE: Application of Affinitech Site Plan Review.

DRAINAGE PATTERNS: THE WEST CHANHASSEN BUSINESS PARK DEVELOPMENT PLAN FROM 2005 ASSUMED THE ENTIRE PROPOSED PROJECT SITE WOULD DRAIN TO ONE REGIONAL OFFSITE FACILITY FOR RATE CONTROL AND TREATMENT. IN EXISTING DRAINAGE PATTERNS, STORMWATER RUNOFF FLOWS OVERLAND AND THROUGH EXISTING STORM SEWER PIPES TO THE OFFSITE FACILITY LOCATED SOUTH-WEST OF THE PROJECT AREA. IN PROPOSED DRAINAGE PATTERNS, STORMWATER WILL FLOW THROUGH ONSITE RAIN GARDENS BEFORE DISCHARGING TO EXISTING STORM SEWER INFRASTRUCTURE AND ROUTING TO THE SAME OFFSITE REGIONAL FACILITY. VEGETATION: EXISTING VEGETATION WILL REQUIRE CLEARING & GRUBBING DUE TO ALTERING GRADES. VEGETATION WILL BE ESTABLISHED IN PROPOSED CONDITIONS IN ACCORDANCE WITH THE LANDSCAPING PLAN. RAINFALL INFORMATION: RAINFALL INFORMATION - THE AVERAGE TOTAL ANNUAL PRECIPITATION IS ABOUT 28.32 INCHES. OF THIS ABOUT 17.31 INCHES, OR 61 PERCENT, USUALLY FALLS IN MAY THROUGH SEPTEMBER. THE AVERAGE ANNUAL SNOWFALL IS 57.3 INCHES. 1.5 CONSTRUCTION SITE ESTIMATES PROJECT AREA SUMMARY: TOTAL PROJECT AREA: 2.82 ACRES CONSTRUCTION SITE AREA TO BE DISTURBED: 2.66 ACRES IMPERVIOUS AREAS: IMPERVIOUS AREA BEFORE CONSTRUCTION (ACRES): 0.32 IMPERVIOUS AREA AFTER CONSTRUCTION (ACRES): 2.19 1.6 RECEIVING WATERS CONSTRUCTION PHASE STORM WATER SYSTEM DESCRIPTION: SILT FENCE AND INLET PROTECTION DEVICES WILL ENSURE RETENTION OF CONSTRUCTION PHASE SEDIMENT DISCHARGE ONSITE AND PROTECT DOWNSTREAM RECEIVING WATERS. DESCRIPTION OF RECEIVING WATERS: STORMWATER RUNOFF FROM THE SITE DISCHARGES TO ONE REGIONAL STORMWATER POND. THE SITE IS WITHIN 1 MILE FROM IMPAIRED WATERS HAZELTINE LAKE AND BLUFF CREEK. HAZELTINE LAKE IS IMPAIRED FOR NUTRIENTS, AND BLUFF CREEK IS IMPAIRED FOR FISH BIOASSESSMENTS AND TURBIDITY. 1.7 SITE FEATURES AND SENSITIVE AREAS TO BE PROTECTED THE SITE HAS NO INTERNAL FEATURES TO BE PROTECTED. 1.8 POTENTIAL SOURCES OF POLLUTION POTENTIAL SOURCES OF SEDIMENT AND OTHER POLLUTANTS TO STORMWATER RUNOFF: CONSTRUCTION PHASE POLLUTANT SOURCES ANTICIPATED AT THE SITE ARE DISTURBED (BARE) SOIL, VEHICLE FUELS AND LUBRICANTS, CHEMICALS ASSOCIATED WITH BUILDING CONSTRUCTION, AND BUILDING MATERIALS. WITHOUT ADEQUATE CONTROL THERE IS THE POTENTIAL FOR EACH TYPE OF POLLUTANT TO BE TRANSPORTED BY STORM WATER. 1.9 ENDANGERED/THREATENED SPECIES THE SITE HAS POTENTIAL OF CONTAINING THE NORTHERN LONG EARED BAT, THE TRICOLOR BAT, THE WHOOPING CRANE, THE MONARCH BUTTERFLY, AND THE RUSTY PATCH BUMBLE BEE. IT IS NOT ANTICIPATED THE CONSTRUCTION ACTIVITIES WILL DISRUPT HABITAT OF THESE ENDANGERED SPECIES, HOWEVER IF ANY OF THEM ARE IDENTIFIED, THE CONTRACTOR IS TO STOP WORK IMMEDIATELY AND CONTACT THE ENGINEER OF RECORD. THE WHOOPING CRANE BREEDS, MIGRATES, WINTERS, AND FORAGES IN A VARIETY OF WETLAND AND OTHER HABITATS, INCLUDING COASTAL MARSHES AND ESTUARIES, INLAND MARSHES, LAKES, PONDS, WET MEADOWS AND RIVERS, AND AGRICULTURAL FIELDS. THERE IS ONE GROUP OF CRANES WHICH ARE KNOWN TO MIGRATE THROUGH MINNESOTA. THE NORTHERN LONG EARED BAT ROOSTS SINGLY OR IN COLONIES UNDERNEATH BARK, IN CAVITIES, OR IN CREVICES OF BOTH LIVE AND DEAD TREES. THIS BAT SEEMS OPPORTUNISTIC IN SELECTING ROOSTS, USING TREE SPECIES BASED ON SUITABILITY TO RETAIN BARK OR PROVIDE CAVITIES OR CREVICES. IT HAS ALSO BEEN FOUND, RARELY, ROOSTING IN STRUCTURES LIKE BARNS AND SHEDS. WITHIN HIBERNACULA, SURVEYORS FIND THEM IN SMALL CREVICES OR CRACKS, OFTEN WITH ONLY THE NOSE AND EARS VISIBLE. THE TRICOLOR BAT IS OFTEN FOUND IN CAVES AND ABANDONED MINES DURING THE WINTER. DURING THE SPRING, SUMMER, AND FALL, TRICOLORED BATS ARE FOUND IN FORESTED HABITATS WHERE THEY ROOST IN TREES, PRIMARILY AMONG LEAVES OF LIVE OR RECENTLY DEAD DECIDUOUS HARDWOOD TREES, BUT MAY ALSO BE FOUND IN SPANISH MOSS, PINE TREES, AND OCCASIONALLY HUMAN STRUCTURES. RUSTY PATCHED BUMBLE BEES ONCE OCCUPIED GRASSLANDS AND TALLGRASS PRAIRIES OF THE UPPER MIDWEST AND NORTHEAST, BUT MOST GRASSLANDS AND PRAIRIES HAVE BEEN LOST, DEGRADED, OR FRAGMENTED BY CONVERSION TO OTHER USES. BUMBLE BEES NEED AREAS THAT PROVIDE NECTAR AND POLLEN FROM FLOWERS, NESTING SITES (UNDERGROUND AND ABANDONED RODENT CAVITIES OR CLUMPS OF GRASSES), AND OVERWINTERING SITES FOR HIBERNATING QUEENS (UNDISTURBED SOIL). MONARCH HABITAT REQUIRES MILKWEED AND FLOWERING PLANTS WHETHER IT’S A FIELD, ROADSIDE AREA, OPEN AREA, WET AREA OR URBAN GARDEN. ADULT MONARCHS FEED ON THE NECTAR OF MANY FLOWERS DURING BREEDING AND MIGRATION, BUT THEY CAN ONLY LAY EGGS ON MILKWEED PLANTS.FOR OVERWINTERING MONARCHS, HABITAT WITH A SPECIFIC MICROCLIMATE IS NEEDED FOR PROTECTION FROM THE ELEMENTS, AS WELL AS MODERATE TEMPERATURES TO AVOID FREEZING. THESE CONDITIONS VARY BETWEEN POPULATIONS. FOR THE EASTERN NORTH AMERICAN POPULATION, MOST MONARCHS OVERWINTER IN OYAMEL FIR TREE ROOSTS LOCATED IN MOUNTAINOUS REGIONS IN CENTRAL MEXICO AT AN ELEVATION OF 2,400 TO 3,600 METERS. BOTH THE NORTHERN LONG-EARED BAT AND TRICOLORED BAT ARE GREATLY THREATENED BY WHITE-NOSE SYNDROME (WNS), WHICH HAS CAUSED A DECLINE IN BAT POPULATIONS BY UP TO 99 PERCENT. THIS FUNGAL DISEASE LOOKS LIKE A WHITE FUZZ ON THE BATS FACE. BATS WITH WNS MAY DO STRANGE THIGNS LIKE FLY OUTSIDE IN THE DAYTIME AND WINTER. IF A BAT WITH WNS IS ENCOUNTERED OR SUSPECTED, REPORT THE SIGHTING TO THE MINNESOTA DEPARTMENT OF NATURAL RESOURCES: REPORT WEBSITE: HTTP://WWW.DNR.STATE.MN.US/REPORTBATS/INDEX.HTML REPORT PHONE: 888-345-1730 REPORT EMAIL: MBS.REPORTS@STATE.MN.US TO REPORT UNUSUAL BAT ACTIVITY OR GROUPS OF BATS IN MINNESOTA. THE DNR IS INTERESTED IN WINTER AND SUMMER ROOST SITES –AS WELL AS SICK OR DYING BATS 1.10 HISTORIC PRESERVATION THERE ARE NO KNOWN HISTORIC SITES ON OR NEAR THE CONSTRUCTION SITE. 1.11 APPLICABLE FEDERAL, TRIBAL, STATE OR LOCAL PROGRAMS LOCAL GOVERNING UNIT (LGU) REQUIREMENTS: CHANHASSEN WEST BUSINESS PARK WAS DESIGNED IN 2005 TO SATISFY THE DESIGN REQUIREMENTS BELOW: 1.RATE CONTROL FOR THE 2- (2.80”), 10- (4.10”), AND 100-YEAR (5.90”) TP 40 RAINFALL EVENTS. a.DISCHARGE RATES FOR THE FULL PUD WERE ANALYZED TO EACH MAJOR RUNOFF LOCATION (SOUTH WETLAND, NORTHWEST WETLAND, AND GALPIN BLVD CULVERT) 2.A WATER QUALITY TREATMENT VOLUME (FILTRATION VOLUME) OF 0.306 INCHES OVER THE IMPERVIOUS AREA a.TREATMENT VOLUME (FT^3) = IMPERVIOUS AREA (SF) X 0.34/12 (INCHES) X 0.9 3.A WET POND DESIGNED TO NURP STANDARDS, WITH A DEAD STORAGE CONTAINING A VOLUME EQUIVALENT TO THE RUNOFF FROM A 2.5” RAINFALL EVENT.

APPROPRIATE CONSTRUCTION PHASING, VEGETATIVE BUFFER STRIPS, HORIZONTAL SLOPE GRADING, AND OTHER CONSTRUCTION PRACTICES THAT MINIMIZE EROSION MUST BE PLANNED FOR AND IMPLEMENTED. IN THE NATURAL CONDITION, SOIL IS STABILIZED BY NATIVE VEGETATION. THE PRIMARY TECHNIQUE TO BE USED AT THIS PROJECT FOR FINAL STABILIZATION OF SITE SOIL WILL BE TO PROVIDE A PROTECTIVE COVER OF VEGETATION, PAVEMENT, OR BUILDING. ALL EXPOSED AREAS MUST BE STABILIZED AS SOON AS POSSIBLE (BUT NO LATER THAN THE NEXT WORK DAY) TO LIMIT SOIL EROSION, BUT IN NO CASE LATER THAN 7 DAYS AFTER THE CONSTRUCTION ACTIVITY IN THAT PORTION OF THE SITE HAS TEMPORARILY OR PERMANENTLY CEASED. TEMPORARY SOIL STOCKPILES WITHOUT SIGNIFICANT SILT, CLAY OR ORGANIC COMPONENTS (E.G. CLEAN AGGREGATED STOCKPILES, DEMOLITION CONCRETE STOCKPILES, SAND STOCKPILES) AND THE CONSTRUCTED BASE COMPONENTS OF ROADS, PARKING LOTS AND SIMILAR SURFACES ARE EXEMPT FROM THIS REQUIREMENT, BUT MUST COMPLY WITH SECTION 2.7 OF THIS SWPPP (SECTION 8.4, 9.9, 9.10, AND 23.9 OF THE GENERAL PERMIT). SEDIMENT CONTROL BMPS: THE PURPOSE OF SEDIMENT CONTROL IS TO PREVENT SOIL PARTICLES THAT HAVE BEEN SUSPENDED IN WATER FROM ENTERING SURFACE WATERS, INCLUDING CURB AND GUTTER SYSTEMS AND STORM SEWER INLETS. SEDIMENT CONTROL BMPS HAVE BEEN DESIGNED AS PART OF THIS SWPPP. IF THE DOWN GRADIENT TREATMENT SYSTEM IS OVERLOADED, THE CONTRACTOR IS RESPONSIBLE FOR IMPLEMENTING ADDITIONAL UP GRADIENT SEDIMENT CONTROL PRACTICES OR REDUNDANT BMPS TO ELIMINATE THE OVERLOADING AND MUST AMEND THE SWPPP TO IDENTIFY THE ADDITIONAL PRACTICES. SEDIMENT CONTROL PRACTICES MUST ALWAYS BE ESTABLISHED ON ALL DOWN GRADIENT PERIMETERS AND BE LOCATED UPGRADIENT OF ANY BUFFER ZONES. THE PERIMETER SEDIMENT CONTROL PRACTICES MUST BE IN PLACE BEFORE ANY UP GRADIENT LAND DISTURBING ACTIVITIES BEGIN. THESE PRACTICES MUST REMAIN IN PLACE UNTIL FINAL STABILIZATION IS ACHIEVED (SEE SECTION 8 OF THIS SWPPP). THE TIMING OF THE INSTALLATION OF SEDIMENT CONTROL PRACTICES MAY BE ADJUSTED TO ACCOMMODATE SHORT-TERM ACTIVITIES SUCH AS CLEARING OR GRUBBING, OR PASSAGE OF VEHICLES. ANY SHORT TERM ACTIVITY MUST BE COMPLETED AS QUICKLY AS POSSIBLE AND THE SEDIMENT CONTROL PRACTICES MUST BE RE-INSTALLED IMMEDIATELY AFTER THE ACTIVITY IS COMPLETED. SEDIMENT CONTROL PRACTICES MUST BE INSTALLED BEFORE THE NEXT RAIN EVENT EVEN IF THE ACTIVITY IS NOT COMPLETE. 2.1 MINIMIZE DISTURBED AREA AND PROTECT NATURAL FEATURES AND SOIL CONSTRUCTION PHASED SHALL BE PERFORMED IN ACCORDANCE WITH THE PHASING SCHEDULE ON SHEET C5.03 TO MINIMIZE IMPACTS FROM CONSTRUCTION ACTIVITIES TO DOWNSTREAM RECEIVING WATERS. 2.2 PRESERVE 50 FOOT NATURAL BUFFER THE CONTRACTOR MUST PRESERVE A 50 FOOT NATURAL BUFFER (OR IF A BUFFER IS INFEASIBLE ON THE SITE PROVIDE REDUNDANT SEDIMENT CONTROLS) WHEN A SURFACE WATER IS LOCATED WITHIN 50 FEET OF THE PROJECTS EARTH DISTURBANCES AND STORMWATER FLOWS TO THE SURFACE WATER. THE CONTRACTOR IS NOT REQUIRED TO ENHANCE THE QUALITY OF THE VEGETATION THAT ALREADY EXISTS IN THE BUFFER OR PROVIDE VEGETATION IF NONE EXISTS. 2.3 CONTROL STORMWATER FLOWING ONTO AND THROUGH THE PROJECT MEASURES SHOULD BE TAKEN TO ENSURE THAT “CLEAN” RUNOFF FROM OFF SITE IS DIVERTED AROUND DISTURBED AREAS ON SITE. CARE SHOULD BE TAKEN THAT RE-ROUTING OFF SITE RUNOFF DOES NOT RESULT IN FLOODING OR OTHER ISSUES ON ADJACENT PROPERTIES.

ORDINANCE XXX UPDATING MINIMUM PARKING STANDARDS Planning Director Eric Maass summarized the staff report, noting the updates discussed at the previous meetings regarding minimum parking standards. There were updates to the efficiency unit and one-bedroom parking requirements. There were also updates to parking requirements for assisted living facilities. There were additional updates for requirements for shopping centers. Commissioner Alto asked why there was a difference between full-liquor license parking requirements to non-liquor license parking requirements. Commissioner Schwartz asked why there were no requirements for handicapped parking spots or EV charging stations. Mr. Maass stated that the number of required handicap parking spots are established by the American Disabilities Act and state building code. Staff is supportive of EV charging spaces but did not feel comfortable requiring EV spaces at this point. Commissioner Goff requested clarification on the handicap requirements. He questioned whether the handicapped spaces would be included in the required total parking standards. Mr. Maass stated this would be included in the total parking standards. He did not think this needed to be clarified in the document. Commissioner Schwartz asked if staff would direct developers to this ordinance and the federal requirements to understand compliance requirements. Mr. Maass stated they connect developers with the city building officials to ensure handicap spots are created and in the correct location. Vice Chair Alto opened the public hearing.

SUMMARY Over the course of 2023, the City Council has discussed the lot cover requirements in Chanhassen. At the September 24 work session, the City Council set policy direction to increase the allowed impervious lot cover to 30% in as residential areas, including lots that are zoned Residential Single Family (RSF) and within the city's shoreland overlay district. The proposed ordinance includes reasonable requirements to mitigate impacts and implement best management practices (BMPs) for the area over 25%. 66 Lots within the city's shoreland overlay district that were established prior to 1976 shall be permitted to have lot cover of 30% under the ordinance. Lots established after 1976 will be required to apply for a variance (per DNR shoreland rules). Lots within a Planned Unit Development (PUD) have lot cover requirements that are prescribed by the PUD and are not impacted by this ordinance. There are three exceptions to this because the PUD Ordinance was silent on lot cover and therefore relies on the underlying zoning. Those PUDs are: Ches Mar Farms, Lake Susan Hills, and Mission Hills. The Ordinance is scheduled for a public hearing at the Planning Commission on January 16, 2024 and will be considered by the City Council for adoption on January 22, 2024.
