The proposed area to be mined is located within the Mineral <br />Extraction Overlay District. The underlying district is <br />Commercial Reserve Transition. See attached Surrounding Land <br />Use map showing Sherburne County land use/zoning information. <br />b. Site analysis information such as trees, depth of topsoil, adjacent and on - <br />site buildings and land uses, flood levels, watercourses, and elevation <br />and percent slope within 100 feet beyond the perimeter of the site. <br />The site is overlain with approximately 2 feet of topsoil which <br />will be used to form berms around the mining area. There are <br />some trees around the former farmstead site. Efforts will be made <br />to leave trees adjacent to Highway 169 in place. <br />The site is bounded to the north by 2251 Avenue, to the west by <br />Highway 169, to the south by Extreme Commercial Recreation, <br />and existing Knife River owned mining area to the east. <br />There are no watercourses on site. <br />See the attached Mining Operations Plan for depictions of above <br />and slopes beyond the perimeter of the site. <br />c. The estimated quantity of materials to be extracted. <br />It is estimated that there is 1,000,000 cubic yards of material in this <br />parcel. <br />d. The depth of water tables throughout the proposed extraction site. <br />Based on surrounding well logs and on -site monitoring well, the <br />groundwater elevation is approximately 950' msl. This is <br />approximately 10 below the expected mine floor. <br />e. The average thickness of overburden on the proposed extraction site. <br />Based on exploratory borings on the parcel, there is approximately <br />12 inches of topsoil overburden overlaying the sand and gravel <br />deposit. <br />f. A detailed map of the highways, streets, roads or other public ways, and <br />private easements or private property, upon and along which the material <br />removed shall be transported (haul roads). The map shall identify all <br />proposed haul roads from the proposed excavation site to the Elk River <br />corporate limits. <br />Page 16 <br />P:\Environment\MINNESOTA\Property - Owned\Ernie Toth\P&Z\E Toth Mining Expansion UP Application 2020.docx <br />
