6. Transportation Routes: The primary transportation routes from the mining operations to market are east on 221st Avenue to US Highway 169 with the majority of truck traffic then traveling south on US Highway 169 and the remainder going north. The intersection of 221st Avenue and US Highway 169 has both northbound and southbound acceleration lanes onto US Highway 169 and a southbound right turn lane from US Highway 169 onto 221St Avenue. A small percentage of trucks may travel west on 221St Avenue to serve local markets. An access point will be established on the western portion of the property off of 221St Avenue. The access point will be paved approximately 100' into the Site from 221St Avenue. McCrossan may initially use Tiller's southern access off of 221St Avenue until a large enough area has been opened up and mined on the Site to allow the construction of their access. Average traffic generated from the site range is anticipated to range from 50-100 truck loads a day(100-200 truck trips). 7. a. Physical relationship of site with respect to the community. The Site is located near the northern boundary of Elk River. The site is immediately south of 221St Avenue and just west of US Highway 169. The Tiller Site is situated immediately east of the Site and the Midwest Asphalt's mining operation is located immediately west of the Site. The site is approximately 3 miles north of the developed area of Elk River. The site is located within the Mineral Extraction Overlay District with an underlying R1a Single Family Residential zoning designation as illustrated on Figure 2, Zoning Excerpt. b. Site analysis: The Site is predominantly wooded with irregular topography. It is bounded by mining operations to the east and west. The elevation of the site varies from approximately 996-1072 feet above mean sea level (msl). Mining will occur to an elevation ranging from 949-956 feet above msl. Site terrain is irregular with little topsoil or overburden. Typical slopes ranging from 20-30%. Sheet C1, Existing Conditions, illustrates the current topography of the Site. Mining is proposed to occur to elevations ranging from approximately 946 to 961 feet above msl. Mine faces will be excavated to slopes of approximately 1.5:1 (H:V). There are no wells located on the Site. Based on information on the National Wetland Inventory (NWI) Map, there are no wetlands located on the site, and there is one wetland basin located approximately 1,000 feet northwest of the Site. Tibbits Brook, Rice Lake and a large wetland complex lie northwest of the site on the west side of the abandoned railroad track. Figure 3, NWI Excerpt, illustrates the location of nearby wetlands.
