The site lies immediately south of the existing Elk River Landfill. Other surrounding land uses are primarily agricultural. This property, as well as property to the north, east and south is included in the gravel-mining district studied in the Environmental Impact Statement (ELS) approved by the City of Elk River in June 1994. A small parcel of land located immediately south of the 24-acre southern parcel was not included in the ElS study. The elevation of the site varies from about 1070 to about 960. Mining will occur to an elevation ranging from 952 to 963. A prominent ridge runs in a north south direction through the property. The slopes on the property range from 20-60%. Slopes west of the site are relatively flat at around 6%. Slopes east of the site are more irregular and range from around 8- 20%. A small wetland is located in the extreme southwest corner of the 18 acre parcel to be added to the site. The wetland is located within the 200-foot setback area and the proposed trail system right-of-way. A 140-foot buffer will be maintained between the wetland and the excavation limits. Vegetation will remain and no land disturbing actrivities will occur wihtin the buffer area. 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 is a U.S.G.S. Quad map excerpt that illustrates the site setting. Estimate of Quantity of Material to be Mined: The estimated quantity of additional material to be mined is approximately 800,000 cy. This volume includes an additional 270,000 cy of material as a result of the property transfer and an additional 530,000 cy of material resulting from the additional parcel of property north of 221s' Avenue. This volume includes topsoil and overburden. Depending upon the consistency of material with depth and the occurrence of unsuitable material, the actual amount to be mined may be less. 8
