across Trunk Highway 169 to the west. The location of the Site is illustrated on Figures 1 and 2 <br />in Appendix A. Figure 3 in Appendix A shows the properties zoned for mineral excavation in <br />the surrounding area. <br /> <br />2.8.2 Site Analysis Information <br /> <br />There is very little tree cover in the areas of the proposed mining. The depth to gravel beneath <br />the topsoil is typically less than 12 inches. There are no buildings located on the Site and no <br />buildings are proposed. The nearest buildings are located south of the Site and are associated <br />with a farmstead to be purchased by Schmidt. The Site is not located in the delineated 100-year <br />flood plain and no water courses exist on the Site. Seven separate wetlands are located on the <br />Site, however, it is not anticipated that any of these wetland areas will be altered or <br />hydrologically affected by the proposed mining. The elevations and slopes within 100 feet of the <br />perimeter of the Site are shown on the Existing Conditions Map included as Sheet 1 in <br />Appendix C. <br /> <br />2.8.3 Estimated Quantity of Materials to be Extracted <br /> <br />Approximately 500,000 cubic yards of material will be mined from approximately 14.81 acres of <br />the Site. All of the gravel to be mined is located in existing hills. <br /> o <br /> <br />2.8.4 Depth of Water Table <br /> <br />The general hydrogeologic conditions in the vicinity of the Site were described in the <br />Environmental Impact Statement (EIS) prepared for the Elk River Gravel Mining District, Elk <br />River, Minnesota, prepared by Maier Stewart and Associates, Inc (MSA), dated May 1994 (the <br />1994 EIS). Based on groundwater information in the 1994 EIS, the groundwater elevation is the <br />area of the Site is approximately 950 feet. <br /> <br />Based on a review of the existing site conditions, the water table at the Site may vary from 948- <br />966 feet, based on the elevations of the wetlands. The proposed maximum depth of mining will <br />not extend below five feet above the elevation of the closest wetland to the area being mined (see <br />Sheets 2, 3, and 4, Phasing Plans, Appendix C). <br /> <br /> 2.8.5 Average Thickness of Overburden <br /> <br />Overburden in the areas to be mined at the Site is minimal. <br />than 12 inches below grade. <br /> <br />Gravel is typically'present at less <br /> <br /> 2.9 ~PLAN OF OPERATION <br /> <br />The gravel mining operation will include mining, processing, stockpiling, and hauling of gravel <br /> <br /> LIESCH ASSOCIATES INC. <br />January 2003 Hydrogeologists · Engineers · Environmcmtal Scientists 'Page 3' <br /> <br /> <br />
