A geotechnical evaluation of the site has been completed which included 16 soil borings across the site. <br />A map of the boring locations and detailed description of the soils observed at each is included in <br />Exhibit D — Geotechnical Report. Recommendation provided within the report for design and <br />consideration have been taken into account including performing soil corrections during subgrade <br />preparation and performing dewatering during excavations. <br />Topography of the Project site, collected via LiDAR, is illustrated on Appendix A — Figure 7. Site <br />elevations were shown ranging from 894 to 932 msl. Site topography generally slopes northwest <br />towards Cedar Lake within the western half of the site and south toward Wilkinson Lake within the <br />eastern half. Some areas of steep slopes (12% or greater) are present within the site. <br />NOTE: For silica sand projects, the EAW must include a hydrogeologic investigation assessing the <br />potential groundwater and surface water effects and geologic conditions that could create an <br />increased risk of potentially significant effects on groundwater and surface water. Descriptions of <br />water resources and potential effects from the project in EAW Item 12 must be consistent withthe <br />geology, soils and topography/land forms and potential effects described in EAW Item 11. <br />12. Water resources: <br />a. Describe surface water and groundwater features on or near the site in a.i. and a.ii. below. <br />Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches. <br />Include any special designations such as public waters, shoreland classification and <br />floodway/floodplain, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting <br />lake, and outstanding resource value water. Include the presence of aquatic invasive species <br />and the water quality impairments or special designations listed on the current MPCA 303d <br />Impaired Waters List that are within 1 mile of the project. Include DNR Public Waters <br />Inventory number(s), if any. <br />There are two DNR Public Waters Basins, Cedar Lake (02001200) and Wilkinson Lake (62004300) <br />located partially within the project area. Cedar Lake is located within the western half of the <br />Project site and continues offsite to the north; Wilkinson Lake is located within the east half and <br />continues offsite to the south. There are no DNR Public Waters watercourses, designated wildlife <br />lakes, migratory waterfowl feeding/resting areas, trout streams/lakes, MPCA or MDNR listed <br />calcareous fens, outstanding resource value waters, and county or jurisdictional ditches within or <br />adjacent to the project area. <br />Ten wetland areas have been delineated within the Project site totally approximately 44.1 acres. <br />These wetlands include 2, 3, and 6 wetlands with Wet Meadow, Shallow Marsh, and Shrub-carr <br />plant communities as well as Type 1 farmed wetland areas. <br />Prominent water features located within 1 mile of the project site include the aforementioned <br />Cedar and Wilkinson Lakes, fourteen additional DNR Public Waters Basins, as well as one DNR <br />Public Waters Watercourse. Refer to the table below for a list of the waterbodies. <br />Page 13 <br />
