Soil Information <br />EXHIBIT I <br />At the end of this exhibit are some printouts from the NRCS website that describe many of the <br />typical characteristics of the soils present on the site. Please refer to Exhibit C -2, Soils Map, for <br />an illustration showing the distribution of the soils. <br />According to the Soil Survey of Larimer County, Colorado (United States Department of <br />Agriculture, Soil Conservation Service, May 2009), there are four major soil types within the <br />proposed project site: <br />1. Gravel Pits, <br />2. Loveland Clay Loam, 0 to 1 percent slopes, <br />3. Riverwash, and <br />4. Table Mountain Loam, 0 to 1 percent slopes. <br />The historic location of these soil types is illustrated on Exhibit C -2, Soils Map. Most of the <br />proposed Treiber Lakes site has been previously disturbed by mining activities. Soils depicted <br />on the map are primarily pre- mining (pre -1977) and likely only exist in isolated areas. Since the <br />original mining plan specified removal, storage, and re- spreading of site soils, it is expected that <br />soils on most of the site are a mixture of Loveland Clay Loam and Table Mountain Loam. <br />Gravel Pits <br />No true topsoil exists. Contains extremely gravelly sand and coarse sand from the ground <br />surface to variable depths. <br />Loveland Clay Loam <br />The Loveland Clay Loam is found on floodplains and stream terraces. Soils are typically <br />distributed on relatively flat land forms, from 0 to 1 percent slopes. Depth to groundwater is <br />typically 18 to 36 inches and the soils are occasionally flooded and poorly drained. <br />Riverwash <br />Riverwash soils are generally found on outwash terraces, overflow stream channels, and <br />floodplains. They occur where land form slopes are typically 0 to 3 percent and are somewhat <br />excessively drained. <br />Table Mountain Loam <br />Table Mountain Loam is found on floodplains and stream terraces with relatively flat slopes <br />of 0 to 1 percent. Soils are generally well drained with depths to groundwater of greater than <br />80 inches and the soils are occasionally flooded and poorly drained. <br />Treiber Lakes <br />DRMS 112 Permit Application <br />Page 19 <br />
