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 225'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 6 <br /> P:\Environment\MINNESOTA\Property-Owned\Ernie Toth\P&Z\E Toth Mining Expansion IUP Application 2020.docx <br />
