4) Names and addresses of property owners within 350 feet: See attached Exhibit B. 5) Purpose of Proposed Extraction: The purpose of the proposed extraction is to remove an existing deposit of sand and gravel and process it into construction aggregate. This is a high quality aggregate deposit which will be used to supply construction materials to Elk River and surrounding areas. 6) Estimated Time Required to Complete the Proposed Extraction: Mining activity under the current CUP is nearing completion. Mining of the southern most portion of the site will take approximately one year to complete. 7) Transportation Routes: The amendment will have no impact to traffic routes. Material will be hauled or conveyed directly from ERL's property to Tiller's existing operations without accessing any public roadways. Trucks hauling the material will enter public roadways from existing access points. 8) Physical relationship of site with respect to the community: The site is located near the northern boundary of Elk River. It is immediately west of U.S. Highway 169 and approximately 3 miles north of the developed area of Elk River. 9) Site analysis: The property consists of ERL's operations. In the past, mining has been conducted over the entire site (excluding setback areas) in phases. Each phase of mining was followed by the construction of a phase of the landfill. Currently, other than the 200 foot area, only a small portion of the site remains to be excavated in preparation for landfill construction. A haul road has been constructed within the zone to allow access of equipment and transfer of material between ERL's property and Tiller's operations to the north and south. 10)Estimate of Quantity of Material to be Mined: The estimated quantity of material to be removed from the amended mining area is approximately 750,000 cy. ' 11) Depth of Water Table: The depth of the water table was identified in the EIS prepared for the gravel overlay district within the City of Elk River. The elevation of the ' water table in this area is approximately 955 - 957 feet above mean sea level. No mining will occur within the water table. i~ i~
