Fox Hill Drive SWMP FFooxx HHiillll DDrriivvee Storm Water Management Study Chanhassen, MN Prepared For: David Blieker Denali Custom Homes Prepared By: Alliant Engineering, Inc. 733 Marquette Ave, Suite 700 Minneapolis, MN 55402 June 17th, 2021 Fox Hill Drive _ Stormwater Management Study June 17th, 2022 Alliant Engineering, Inc. Page 1 of 7 210-122 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 – Wooded 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) 2.898 Existing Site Impervious (acres) 0.076 Post Construction Site Impervious (acres) 0.446 New (Increase) in Site Impervious Area (acres) 0.37 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:  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 Fox Hill Drive _ Stormwater Management Study June 17th, 2022 Alliant Engineering, Inc. Page 2 of 7 210-122 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 not alter the bounce in water level.  Discharge to Wetlands 1 must be treated to 90% TSS and 75% 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”) 0.87 0.75 0.32 10-year (4.26”) 2.20 2.51 1.28 100-year (7.38”) 8.22 8.79 4.91 10 day-100 yr Snowmelt 0.27 0.33 0.22 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. Fox Hill Drive _ Stormwater Management Study June 17th, 2022 Alliant Engineering, Inc. Page 3 of 7 210-122 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”)* 0.61 0.91* 0.35 10-year (4.26”) 1.95 2.27 1.22 100-year (7.38”) 6.30 4.81 4.90 10 day-100 yr Snowmelt 0.27 0.33 0.22 *Increase shown at 2-year event. Design allows for infiltration of water quality event prior to allowing for overtopping through grate. After overtopping the grate, it is allowed to discharge overland to the road. This mimics an existing condition scenario where the water overtops a natural EOF at the wetland prior to discharging to Fox Hill Drive. 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∗ (21,744 𝑠𝑓) = 1,993 𝑐𝑓 The site will meet abstraction through multiple infiltration BMP’s. Fox Hill Drive _ Stormwater Management Study June 17th, 2022 Alliant Engineering, Inc. Page 4 of 7 210-122 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 1 397 567 1.8 0.45in/hr 48 Block 2 Lot 1 759 835 1.75 0.45in/hr 46.67 Block 2 Lot 2 346 491 1.25 0.45in/hr 33.33 Block 2 Lot 3 396 456 1.73* 0.45in/hr 46.133 *Effective depth is equal to 1.73’. 6” of base stone and 6” of top stone both with 40% voids and 16” of chamber storage gives a total of 1.73’. 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 high grade wetlands (wetland 1) must meet 90% TSS and 75% TP, 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: Wetland 1 TSS Loading (lbs) TP Loading (lbs) Removal % 100% 100% Total TSS Loading (lbs) TP Loading (lbs) Existing 853.3 4.698 Proposed 375.3 2.167 Removal % 88% 87% Fox Hill Drive _ Stormwater Management Study June 17th, 2022 Alliant Engineering, Inc. Page 5 of 7 210-122 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”) - 64.0 - 63.2 2-year (2.87”) - 66.2 - 65.4 10-year (4.26”) 1.14 71.8 0.93 68.0 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. Erosion and Sediment Control Plan The following Best Management Practices (BMP’s) are proposed for the project. Fox Hill Drive _ Stormwater Management Study June 17th, 2022 Alliant Engineering, Inc. Page 6 of 7 210-122 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. 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.

the SC-310-3 Chamber allows for a design option for sites where limited cover, limited space, high water table and escalated aggregate cost are a factor. The SC-310-3 has a minimum cover requirement of 16” (400 mm) to bottom of flexible pavement and reduces the spacing requirement between chambers by 50% to 3” (76 mm). This provides a reduced footprint overall, reduces aggregate needed, and allows the designer to offer a traffic bearing application yet comply with water table separation regulations. StormTech chambers can also be used in conjunction with Green Infrastructure, thus enhancing the performance and extending the service life of these practices.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. Custom Soil Resource Report 8 The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

Custom Soil Resource Report 16 Soil Information for All Uses Soil Properties and Qualities The Soil Properties and Qualities section includes various soil properties and qualities displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group (Fox Hill Drive Hydrologic Soil Group) Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 17 Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

Soil Survey Area: Carver County, Minnesota Survey Area Data: Version 18, Sep 10, 2021 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: May 30, 2020—Jul 3, 2020 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.
