Fox Hill Drive SWMP FFooxx HHiillll DDrriivvee Storm Water Management Study Chanhassen, MN Prepared For: Chad Mayes Denali Custom Homes Prepared By: Alliant Engineering, Inc. 733 Marquette Ave, Suite 700 Minneapolis, MN 55402 August 15th, 2021 Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 1 of 9 210-122 Introduction Included in this report are the materials necessary for review of the proposed stormwater management plan for the Fox Hill Drive residential development in Chanhassen, Minnesota. This stormwater management plan was designed to meet the rules established by the City of Chanhassen and Riley Purgatory Bluff Creek Watershed District. Background This hydrologic study was conducted to analyze the stormwater treatment requirements for the proposed Fox Hill Drive development in Chanhassen, Minnesota. The goal of the study is to design stormwater treatment facilities that can handle the increased impervious cover resulting from the new development. This study compares the following two scenarios:  Existing conditions – Unmaintained Wooded Area with lots of tree litter and debris with single family residential home.  Proposed conditions –Low-Density Single-Family Development Project Area Total Site Area based on boundary (acres) 2.465 Total SWMP Area including Offsite Area (acres) 3.015 Existing Site Impervious (acres) 0.076 Post Construction Site Impervious (acres) 0.537 New (Increase) in Site Impervious Area (acres)* 0.461 Total Disturbed Area (acres) 1.455 * The proposed development includes a total of 4 single family lots. The property currently contains topography varying in elevation from 970 ft (high point near north central point of the site) to 898 ft (Lotus Lake edge). Please refer to the preliminary plat submittal plan documents for additional design information on the proposed development. The stormwater management plan for proposed site conditions will meet the guidelines set forth by the City of Chanhassen and RPBCWD regarding stormwater discharge rate control, water quality, and volume abstraction. The plan will also meet rules for erosion and sediment control. The following criterion was used in designing the stormwater management system: Rate Control:  Post-development peak runoff rates from the site for the 2, 10, 100-yr, 10 day-100 yr Snowmelt MSE 3 24-hr storm events must not be greater than the existing condition rates. Water Quality: Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 2 of 9 210-122  If the project conforms to the 1.1-inch rule there is no further pollutant removal requirement  No net increase for TSS, TP, and annual volume runoff Infiltration/Volume Control:  Infiltration of stormwater is required for a volume that is equal to or greater than 1.1 inches of runoff from the new impervious area created by the development.  Infiltration should occur within 48 hours or less. Wetland Protection:  Proposed discharge to wetland should meet the watershed criteria for a medium grade wetland  Discharge to Wetland 1 must meet abstraction requirements or 90% TSS and 60% TP. Runoff Rate Control All rate control calculations have been performed using the SCS method via HydroCAD software. HydroCAD curve numbers were used for all calculations. Three events were modeled including: the 2- year, 10-year and 100-year, 10 day-100 yr Snowmelt event, MSE 3 24-hour storm events with ATLAS-14 precipitation amounts of 2.87, 4.26, 7.38, and 7.20 inches used, respectively. The analysis demonstrates that the proposed peak rates of runoff from the site are equal or less than the pre-development rates for all modeled events. Existing Conditions The existing project area includes a total on-site impervious surface area of 0.076 acres The site currently consists of primarily open space with a single family home, forested areas, and green space. Soil types were determined from the Geotechnical Report or Web Soil Survey (attached in Appendix). Based on given information the site was modeled in HydroCAD with generally B soils. Curve numbers were approximated based on land cover types from aerial photos. Offsite drainage flows through the site due to being downstream of higher ground. Offsite area was included in the design to ensure correct water levels in existing and preserved wetlands. To compare peak discharge rates and volumes for the existing and proposed conditions, flows were analyzed at 3 discharge locations. Refer to existing conditions drainage map and HydroCAD results for additional information and calculations. Pre-Development Runoff Rates as calculated by HydroCAD: Rainfall Event Wetland 1 Northwest Lotus Lake [cfs] [cfs] [cfs] 2-year (2.87”) 3.82 4.09 2.73 10-year (4.26”) 7.06 7.84 5.23 100-year (7.38”) 14.74 16.80 11.23 10 day-100 yr Snowmelt 0.27 0.33 0.23 Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 3 of 9 210-122 Proposed Conditions The proposed development will disturb 1.455 acres and includes a total on-site impervious surface area and offsite disturbed or new impervious of 0.446 acres. The proposed development will use multiple infiltration BMP’s and pretreatment to provide water quality, rate control, and volume abstraction for the development. This best management practice (BMP) was the best option suitable for site conditions. Rate Control The proposed stormwater management plan decreases the total peak discharge rates to at or below existing conditions for all modeled events. Refer to proposed conditions drainage map and HydroCAD results for additional information and calculations. Post-Development Runoff Rates as calculated by HydroCAD: Rainfall Event Wetland 1 Northwest Lotus Lake [cfs] [cfs] [cfs] 2-year (2.87”) 3.33 3.31 1.47 10-year (4.26”) 6.49 6.18 4.73 100-year (7.38”) 13.61 9.41 11.06 10 day-100 yr Snowmelt 0.31 0.34 0.23 See preliminary plat/final plat plans for EOF info, HWL’s and OCS structure details. Stormwater Volume Abstraction Volume Required Because the project disturbs more than 50% of the existing site impervious area and increases the overall site impervious area by more than 50%, the total volume required must be a 1.1” abstraction of the entire site impervious area, per RPBCWD rules. Infiltration volumes calculated on maximum allowable impervious for block 2 lots 1-3 per City 25% impervious rule or maximum build per setback requirement (see PDRN). Parcel impervious = 21,744 SF (0.499 acres) Required Abstraction for development: 1.1 𝑖𝑛 (𝑎𝑏𝑠𝑡𝑟𝑎𝑐𝑡𝑖𝑜𝑛)∗1 𝑓𝑡 12 𝑖𝑛∗ (24,000 𝑠𝑓) = 2,200 𝑐𝑓 The site will meet abstraction through multiple infiltration BMP’s. Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 4 of 9 210-122 Volume Provided For calculation purposes, the BMP’s were modeled using soils with an infiltration rate of 0.45 in/hr. See table below for infiltration depth in each basin. OCS to be constructed to control release of runoff and set infiltration depths. See planset for OCS details. See planset and Geotech report or Web Soil Survey for further details. Infiltration Volume Summary BMP Location Volume Required (CUFT) Volume Provided (CUFT) Depth (ft) Infiltration Rate (in/hr) Drawdown Time (hrs) Block 1 Lot 1 540 544 1.31 0.3275 In/hr 48 Block 2 Lot 1 938 945 1.42 0.355 in/hr 48 Block 2 Lot 2 417 417 0.8 0.2 in/hr 48 Block 2 Lot 3 424 425 0.74 0.185 in/hr 48 *Effective depth is equal to 0.8’. 6” of base stone and with 40% voids and 0.68[ of chamber storage gives a total of 0.88’. Block 2 - Lots 1 and 2 shall be overexcavated until SP or SP-SM soils are encountered, backfill with free draining material. Water Quality Water quality was modeled in MIDS to meet both watershed and city requirements for nutrient removal. Additionally, sump manholes will be installed in the structures immediately upstream of the BMP before discharging to the BMP. MIDS was used to model to show no net increase in TP, TSS and Annual Volume for BMP’s. See MIDS results in Appendix. Discharge to medium grade wetlands (wetland 1) must meet 90% TSS and 60% TP or the abstraction requirement, however buffer is self-treating so all disturbed area that is buffered does not require treatment, the remaining area and impervious will be treated by an infiltration BMP. Summary of MIDS results: Total TSS Loading (lbs) TP Loading (lbs) Existing 58.9 0.324 Proposed 28.7 0.158 Removal % 90% 90% *Areas excluded from the MIDS include previously approved plans for lakeshore restoration and any area that the city/watershed will require wetland buffer or conservation easement. Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 5 of 9 210-122 Wetland Protection: As shown when discussing proposed runoff, rates going to the wetland will be below existing rates for the 2-, 10-, 100-year events and 10 day-100 year snowmelt. Additionally, the infiltration basin will be the primary outlet for stormwater, which meets the required phosphorus and TSS removal efficiency required for the wetland. Direct discharge to the wetland will only occur as part of undisturbed existing drainage areas. The watershed has 4 requirements for wetlands shown below: Wetland 1 Rainfall Event Ex. Bounce Ex. Inundation Pr. Bounce Pr. Inundation [ft] [hrs] [ft] [hrs] 1-year (2.50”) - 12.0 - 12.0 2-year (2.87”) - 12.0 - 12.0 10-year (4.26”) 0.19 12.2 0.0 12.2 The above tables summarize the required info. Based on the runoff rates and volume routed to the wetland there will be no detrimental effects to these wetlands from the proposed development. The runout elevation for the wetland will not be changed. Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 6 of 9 210-122 Watershed Rule G Criteria: 3.1 Use of the bed or banks of a waterbody must meet: a a demonstrated public benefit for projects affecting public waters or b a demonstrated specific need for all other waterbodies. 3.2 Construction, replacement or improvement of a waterbody crossing in contact with the bed or bank of a waterbody: a Will retain adequate hydraulic capacity and assure no net increase in the flood stage of the pertinent waterbody; b Will retain adequate navigational capacity pursuant to the waterbody’s recreational classification. c Must not be reasonably likely to affect water quality, change the existing flowline/gradient, or cause increased scour, erosion or sedimentation; d Will provide wildlife passage along each bank and riparian area and fish passage in the waterbody by means that account for wildlife that are native to the area or may be present. e Will represent the ‘minimal impact’ solution to a specific need with respect to other reasonable alternatives, based on analysis of at least two reasonable alternatives, one of which may be not undertaking the proposed work. 3.3 Construction or improvement of an outfall structure in contact with the bed or bank of a waterbody must: a incorporate a stilling-basin, surge-basin, energy dissipator, or other device or devices when necessary to minimize disturbance and erosion of natural shoreline and bed resulting from peak flows; b when feasible, utilize discharge to stormwater treatment ponds, artificial stilling or sedimentation basins, or other devices for entrapment of floating trash and litter, sand, silt, debris, and organic matter prior to discharge to public waters; and c use natural or artificial ponding areas to provide water retention and storage for the reduction of peak flows into waterbodies to the greatest extent possible 3.5 Placement or replacement of a structure must: a Represent the minimal impact solution to a specific need with respect to all other reasonable alternatives; b Represent the minimum encroachment, change or damage to the environment, particularly the ecology of the waters, necessary to achieve the intended purpose; c Comply with the District floodplain rule; and d Not be reasonably likely to cause adverse effects to water quality and the physical or biological character of the waterbody. Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 7 of 9 210-122 3.1 a Currently there is no secondary emergency access to Big Woods Blvd resulting in a 1200 LF dead end street which exceeds city standards. To treat the proposed stub road and the fact that any existing outfall to Lotus Lake is not in close enough proximity to connect to a new outfall is being proposed. The outfall is being proposed in a manner to minimize disturbance to Lotus Lake and existing shoreline. As part of the work for the development the property owner will be restoring the shoreline which has been neglected further providing a benefit to Lotus Lake. 3.2a The flood storage of Lotus Lake will not change as part of this work. In existing conditions the all existing impervious from Fox Hill Drive is routed to the lake without treatment. Proposed will treat 2400 SF of existing fox hill drive. All rate control is met. b. Will not change navigability. As the streamline will be reinforced/protected. c. See b and calculations for treatment. d. will not inhibit wildlife passage as it is significantly below the earth’s surface until it’s outlet where the impact will be minimal. e. see response above. 3.3 a incorporates rip rap and utilizes a natural stilling basin based on existing topography b. See 3.3a c complies with district floodplain as no fill is placed below the HWL of Lotus Lake. d. see calculations for water treatment Erosion and Sediment Control Plan The following Best Management Practices (BMP’s) are proposed for the project. Temporary erosion control devices shown on the grading plan to provide sediment control during project construction include:  Silt fence  Rock construction entrance  Inlet sediment barriers at catch basins  Diversion berms  Erosion Control Blanket Permanent erosion control devices shown to be installed include:  Rip rap at storm sewer pipe outlets  Turf reinforcement mat at emergency spillways  Turf establishment including seeding, sodding, vegetation, etc. Fox Hill Drive _ Stormwater Management Study August 15th, 2022 Alliant Engineering, Inc. Page 8 of 9 210-122 Conclusion Alliant Engineering believes that the proposed stormwater management plan is acceptable for all parties involved. The total proposed peak discharge rates for the 2-year, 10-year, 100-year and 10 day-100 yr snowmelt 24-hour storm events will be matched or reduced from existing conditions modeled rates. The proposed stormwater management system meets the volume abstraction requirements with the use of an infiltration/filtration basin. Water quality requirements are provided through the same infiltration/filtration basin and provide the TP and TSS removal efficiencies required. The proposed grading and erosion control plan will utilize BMPs whenever possible to provide adequate erosion control measures to prevent erosion and contain sediment during construction.

It was a sparsely vegetative basin and drained to the west during high precipitation events. • The soil survey showed no hydric and partially hydric soil types on the property. • The National Hydrography Dataset showed one water body located within the eastern property boundary. 581 Fox Hill Drive, Chanhassen Wetland Delineation Report 2 2. OVERVIEW The 2.39-acre 581 Fox Hill Drive site was inspected on October 10, 2020 for the presence and extent of wetland. The property was located in the Southeast ¼ of Section 1, Township 116 North, Range 23 West, City Chanhassen, Carver County, Minnesota. The site was situated east of Big Woods Boulevard and south of Fox Hill Drive (Figure 1). The property corresponded to Carver County PID 250010200. The site consisted of residential single-family home lot with a mature canopy of red oak and sugar maple trees. The topography sloped from an elevation of 968 feet msl in the central portion of the to a low of 898 feet msl in the eastern portion of the site. The property was bordered on the west by Big Woods Boulevard, on the east by Lotus Lake (DNR Public Water 10- 6 P), on the south by a single-family home, and on the north by Fox Hill Drive. One wetland was delineated within the site boundaries. The delineated wetland boundaries and existing conditions are shown on Figure 2. Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for: (1) a wetland boundary and type determination under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence and an Approved Jurisdictional Determination (AJD) under Section 404 of the Federal Clean Water Act. 3. METHODS Wetlands were identified using the Routine Determination method described in the Corps of Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region (Version 2.0) as required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Wetland boundaries were identified as the upper-most extent of wetland that met criteria for hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were marked with pin flags that were located by a Trimble R1 GPS unit. Soils, vegetation, and hydrology were documented at a representative location along the wetland- upland boundary. Plant species dominance was estimated based on the percent aerial or basal coverage visually estimated within a 30-foot radius for trees and vines, a 15-foot radius for the shrub layer, and a 5-foot radius for the herbaceous layer within the community type sampled. Soils were characterized to a minimum depth of 24 inches (unless otherwise noted) using a Munsell Soil Color Book and standard soil texturing methodology. Hydric soil indicators used 581 Fox Hill Drive, Chanhassen Wetland Delineation Report 3 are from Field Indicators of Hydric Soils in the United States (USDA Natural Resources Conservation Service (NRCS) in cooperation with the National Technical Committee for Hydric Soils, Version 8.1, 2017). Mapped soils are separated into five classes based on the composition of hydric components and the Hydric Rating by Map Unit color classes utilized on Web Soil Survey. The five classes include Hydric (100 percent hydric components), Predominantly Hydric (66 to 99 percent hydric components), Partially Hydric (33 to 65 percent hydric components), Predominantly Non-Hydric (1 to 32 percent hydric components), and Non-Hydric (less than one percent hydric components). Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2016 National Wetland Plant List (U.S. Army Corps of Engineers 2016. National Wetland Plant List, version 3.3, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory, Hanover, NH). 4. RESULTS 4.1 Review of NWI, Soils, Public Waters and NHD Information The National Wetlands Inventory (NWI) (Minnesota Geospatial Commons 2009-2014 and U.S. Fish and Wildlife Service) showed one L2ABH deep water habitat located within the property boundaries (Figure 3). The Soil Survey (USDA NRCS 2015) did not show any hydric and partially hydric soil types on the property. Predominantly non-hydric soils included Lester-Kilkenny soils. Soil types mapped on the property are listed in Table 1 and a map showing soil types is included in Figure 4. Table 1. Soil types mapped on the 581 Fox Hill Drive site Symbol Soil Name Acres % of Area % Hydric Hydric Category KC Lester-Kilkenny loams, 6 to 12 percent slopes 2.3 74.7% 0 Non-hydric KD Lester-Kilkenny loams, 12 to 18 percent slopes 0.6 19.0% 0 Non-hydric KF Lester-Kilkenny complex, 22 to 40 percent slopes 0.1 4.6% 0 Non-hydric W Water 0.0 1.6% 0 Non-hydric The Minnesota DNR Public Waters Inventory (Minnesota Department of Natural Resources 2015) showed that the eastern site boundary bordered Lotus Lake (DNR Public Water 10-6 P) (Figure 5). The National Hydrography Dataset (U.S. Geological Survey 2015) showed that the property bordered Lotus Lake to the east (Figure 6). 581 Fox Hill Drive, Chanhassen Wetland Delineation Report 4 4.2 Wetland Determinations and Delineations Potential wetlands were evaluated during field observations on October 14, 2020. One wetland was identified and delineated on the property (Figure 2). Corresponding data forms are included in Appendix B. The following description of the wetlands and adjacent uplands reflects conditions observed at the time of the field visit. Herbaceous vegetation was actively senescing at the time of the wetland delineation. Precipitation conditions were within the normal range based on available 30-day rolling total precipitation and three-month antecedent precipitation data (Appendix C). Wetland 1 was a Type 1 (PEM1A) seasonally flooded basin wetland located in western portion of the property. The wetland consisted of a sparsely vegetated basin situated in a mature oak and maple forest with little to no understory vegetation. Saturation at the soil surface was observed throughout the wetland. This wetland covered 0.11 acre within the property boundaries. Adjacent upland consisted of mature forest dominated by red oak and sugar maple trees. Primary and secondary hydrology indicators were not observed on the upland. The wetland boundary corresponded to a topographic rise that coincided with a transition from saturated soil to dry soils associated with red oak and sugar maple trees. The wetland was not shown on the NWI map and was mapped as fell in an area mapped as non-hydric soil (Lester- Kilkenny loam) on the soil survey. Wetland 1 drained overland to the west. 4.3 Other Areas Other areas were investigated because they were: (1) observed to support a hydrophytic plant community, (2) had visible wetland hydrology indicators, (3) were shown as wetland on the NWI map, or (4) were depressional and mapped as hydric soil. Field investigation led to the conclusion that these areas were not wetland. Sample Point A was adjacent to Lotus Lake located in the eastern portion of the site that was shown as a L2ABH wetland on the NWI map but was mapped as Lester-Kilkenny soils (non- hydric) on the soil survey. This area was dominated by a canopy of sugar maple trees with an understory containing common buckthorn, meadow rue, and tree saplings. Soils in this area were non-hydric and consisted of black sandy clay loam over light olive brown sandy clay loam. High chroma soil color from 8-18 inches indicated the soils were non-hydric and the area lacked primary and secondary indicators of wetland hydrology. No other areas with hydrophytic vegetation or wetland hydrology were observed on the site. No other areas were shown as hydric soil on the soil survey or as wetland on the NWI map. 4.4 Request for Wetland Boundary and Jurisdictional Determination Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for: (1) a wetland boundary and type 581 Fox Hill Drive, Chanhassen Wetland Delineation Report 5 determination under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence and an Approved Jurisdictional Determination (AJD) under Section 404 of the Federal Clean Water Act. 581 Fox Hill Drive, Chanhassen Wetland Delineation Report 6 5. CERTIFICATION OF DELINEATION The procedures utilized in the described delineation are based on the U.S. Army Corps of Engineers 1987 Wetlands Delineation Manual as required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act.
