Rate Control Per Valley Branch Watershed District standards, runoff rates must be equal to, or less than, the existing rates. Rate control must be met for the 2-, 10-, and 100-year storms. In addition,the 100-year 10-day snowmelt runoff must also be met. The rainfall amounts were found in the VBWD Rule 2.

The required amount of water that must be infiltrated is equal to 1.1" over the new impervious surface. New Impervious = 235,984 SF Required Infiltration = 1.1" x 235,984 SF = 21,632 CF Soil borings were obtained and showed that in all areas where infiltration is proposed, the most restrictive soil type is Type C ML soils. These soils allow for an infiltration rate of 0.2 in/hr. Infiltration will be achieved in a new basin constructed in the northwest corner of the property. In addition to receiving water from the new parking lot on the north, water from the existing parking lot will be redirected to the new infiltration basin. Only the volume below the outlet will be included in the infiltration volume. The outlet elevation is designed to allow for a drawdown time of 48 hours.

INTRODUCTION The Stillwater High School site was examined on June 11,2015 for the presence and extent of wetland. The approximately 140-acre site was located at 5701 Stillwater Blvd N in Section 5 & 6,Township 29,Range 20,Oak Park Heights,Washington County,Minnesota. Generally the site was located immediately east of Stillwater Blvd N and south of 58th St N(Figure 1). Site limits were comprised of Washington County PIDs 0602920140004, 0602920140005, 0602920140006, 0602920410002. The northern portion of the site consisted of a large building containing Stillwater High School, as well as several large parking lots. The southern portion of the site contained several baseball fields, a football arena, and grassy practice fields. Several maintenance outbuildings were present along the western edge of the property boundary. A small waterbody surrounded by disturbed woodland was located along the southern edge of the site boundary. Single-family residential housing was located to the east, south, and west of the site boundaries. Numerous businesses were located north of 58th St N including Super America,The UPS Store, and Kowalksi's Market. II. METHODS Wetlands were identified using Routine Determination methodology described in the Corps of Engineers Wetland Delineation Manual(Waterways Experiment Station, 1987)and Regional Supplement to the Corps of Engineers Wetland Delineation Manual:Northcentral and Northeast 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 and were located by Cornerstone Land Surveying, Inc. 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 18-24 inches(unless otherwise noted)utilizing Munsell Soil Color Charts and standard soil texturing methodology. Hydric soil indicators used 2 in reporting are from Field Indicators of Hydric Soils in the United States (USDA Natural Resources Conservation Service in cooperation with the National Technical Committee for Hydric Soils,Version 7, 2010). Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2014 National Wetland Plant List(U.S. Army Corps of Engineers 2014. National Wetland Plant List,version 3.2, https://wetland plants.usace.armv.mil Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory,Hanover,NH). III. RESULTS Review of NWI,Soils,DNR,and NIID Information The National Wetlands Inventory(NWI) (Minnesota Geospatial Commons 2009-2014, https://gisdata.mn.gov/dataset/water-nat-wetlands-inv-2009-2014) showed six wetlands within the site boundaries (Figure 3). The Soil Survey of Washington County,Minnesota (http://soils.usda.gov/survey/geography/ssurgo/) showed the following soil types within or near site boundaries (Figure 4). Soil series information is summarized below in Table 1. Map Map Unit Name Hydric Category Unit 49 Antigo silt loam,0 to 2 percent slopes Predominantly Non-Hydric 49C Antigo silt loam,6 to 12 percent slopes Predominantly Non-Hydric 120 Brill silt loam Predominantly Non-Hydric 153B Santiago silt loam,2 to 6 percent slopes Non-Hydric 153C Santiago silt loam,6 to 15 percent slopes Non-Hydric 155C Chetek sandy loam,6 to 12 percent slopes Non-Hydric 155D Chetek sandy loam,12 to 25 percent slopes Non-Hydric 189 Aubumdale silt loam Predominantly Hydric 266 Freer silt loam Predominantly Non-Hydric 301B Lindstrom silt loam,2 to 4 percent slopes Predominantly Non-Hydric 342D Kingsley sandy loam,12 to 18 percent slopes Non-Hydric 1055 Aquolls and Histosols,ponded Predominantly Hydric 3 The Minnesota DNR Public Waters Map, Washington County (https://gisdata.mn.gov/dataset/water-mn-public-waters) showed two DNR Public Waters (Cloverdale Lake&Mcdonald Lake) south of the site boundary and two DNR Public Waters (Unnamed 82-316W&Unnamed 82-315W)west of the site boundary(Figure 5). The National Hydrography Dataset(U.S. Geological Survey, (http://nhd.usgs.gov/) showed no waterbodies within the(Figure 6). Wetland Determinations and Delineations Potential wetlands were evaluated in greater detail during field observations on June 11, 2015. Four(4)wetlands were identified and delineated on the subject site(Figure 2). Corresponding data forms are included in Appendix A. The following description of the wetlands and adjacent upland reflects conditions observed at the time of the field visit.At that date,herbaceous vegetation and crops were actively growing and hydrologic conditions were assumed to be typical for that date based on available precipitation data(Appendix B)and field observations. A survey of the wetland boundaries is included as Appendix C. Wetland 1 was a Type 4 (PEMF)deep marsh wetland dominated by cattail and reed canary grass. The wetland soils were very dark brown loam over depleted sandy loam. The wetland soils were saturated at the surface,with free water observed at 8"below the soil surface at the sample location. No apparent inlets or outlets were observed within Wetland 1. Adjacent upland at the sample point was dominated by Kentucky bluegrass. The delineated boundary followed a change in vegetation composition and topography.Wetland 1 corresponded to a PEM 1 C/PUBGx/PEM 1 A wetland on the NWI map, and is located in an area mapped with Antigo silt loam(Predominantly Non-hydric)on the soil survey. Wetland 2 was a Type 3 (PEMC) shallow marsh wetland dominated by cattail. The wetland soils were dark gray sandy loam with redox concentrations. The wetland soils were saturated at the surface,with free water observed 2"below the soil surface at the sample location. Adjacent upland at the sample point was dominated by Kentucky bluegrass. The delineated boundary followed a change in vegetation composition and topography. Wetland 2 did not correspond to a wetland on the NWI map, and is located in an area mapped with Brill silt loam(Predominantly Non-hydric)on the soil survey.No apparent inlets or outlets were observed within Wetland 2. Wetland 3 was a Type 2/3 (PEMB/C) shallow marsh wetland dominated by bluejoint grass, sedge,cattail and reed canary grass. The wetland soils were very dark gray loamy sand over depleted loamy sand. The wetland soils were saturated at the surface,with free water observed at 1"below the soil surface at the sample location. Wetland 3 extended off-site to the east. Adjacent upland at the sample point was dominated by Kentucky bluegrass. 4 r The delineated boundary followed a change in vegetation composition and topography. Wetland 3 corresponded to a PEM1C/PEM1A wetland on the NWI map, and is located in an area mapped with Aquolls and Histosolls (Predominantly Hydric) on the soil survey. Wetland 4 was a Type 5 (PABH) open water wetland. The wetland soils were black sandy mucky loam containing redox concentrations. The wetland soils were saturated at the surface, with free water observed at 4"below the soil surface at the sample location. Adjacent upland at the sample point was dominated by a canopy of red pine and sugar maple with an understory of sugar maple and buckthorn. The delineated boundary followed a change in vegetation composition and topography. Wetland 4 corresponded to a PEM 1 C/PABG wetland on the NWI map, and is located in an area mapped with Lindstrom silt loam(Predominantly Non-hydric)and Chetek sandy loam(Non-hydric)on the soil survey. Wetland 4 extended off-site to the south. Other Areas Sample Point A was taken in a shallow depressional area located due east of the Stillwater High School football arena. Soils in this area were brown sandy clay loam, and did not fulfill any hydric soil indicators. This area also lacked primary and secondary hydrology indicators. For these reasons this area was not delineated as wetland. No other areas with wetland vegetation or hydrology were observed on the site. No other areas were shown with hydric soil on the soil survey map, or as wetland on the NWI map. 5 V. CERTIFICATION OF DELINEATION The procedures utilized in the described delineation are based on the COE 1987 Wetland Delineation Manual as required by Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Both the delineation and report were conducted in compliance with regulatory standards in place at the time the work was completed. All site boundaries indicated on figures within this report are approximate and do not constitute an official survey product.
