'~~~Y n'~~' l/ Di.,°-:~... ~ r~_~r ~ r lion, Exhibit I -Sods Information r;•;, ~ $ 2-.• :.e;~;y The following was taken from the "Soil Survey of Fremont County Area, Colorado" obtained from the local Natural Resources Conservation Office (N.R.C.S.) in Canon City. Please see Attachment I-1, a copy of the soils map of the area (from the above publication). The soil type on the slope is Wesix very channery loam (Map Unit No. 125). Typically, the surface layer is brown very channery loam about 8 inches thick. The substratum is very channery loam about 5 inches thick. Limestone bedrock is at a depth of about 13 inches. The soil is moderately alkaline. Included with this soil in mapping are areas of limestone outcrop, which make up about ]0 percent of the unit. Permeability is moderate in the Wesix soil, and available water capacity is very low. Effective rooting depth is 7 to 20 inches. Runoff is medium to very rapid, and the hazard of water erosion is slight to very high. The potential plant community of the Wesix soil type is mainly pinion and juniper and an understory of sideoats grams, blue grams, Scribner needlegrass, and Indian ricegrass. The potential production of native understory vegetation in normal years is about 200 pounds of air- dry vegetation per acre. If the condition of the understory deteriorates, blue grams, red threeawn, yucca broom snakeweed, and other forbs and shrubs increase. Woodland products, such as firewood, fence posts, Christmas trees, and pinyon nuts, are produced in areas of the Wesix very channery loam soil. The average site index of pinyon and juniper is about 55. The soil type just below the slope is Rizozo-Neville complex (Map Unit No. 93). The transition between the Wesix soil and the Rizozo-Neville complex is rather obscure, but a portion of the affected land will occur in this soil complex. The Rizozo-Neville soil complex is typically used as rangeland. The Rizozo soil is shallow and well drained. It formed in residuum derived dominantly from red sandstone. Slopes range from 10 to 30 percent. The surface layer is typically weak red channery loam about 3 inches thick. The substratum is pale red loam about 10 inches thick. Hard, pale red sandstone is at a depth of about 13 inches. The soil is moderately alkaline. Permeability is moderate in the Rizozo soil. Available water capacity is very low. Effective rooting depth is 4 to 20 inches. Runoff is rapid or very rapid, and the hazard of water erosion is high or very high. The potential plant community on the Rizozo soil mainly pinyon and juniper and an understory of sideoats grams, blue grams, and Scribner needlegrass. The potential production of native understory vegetation on the Rizozo soil is about 200 pounds of air-dry vegetation per acre. If • the condition of the understory deteriorates, blue grams, pricklypear, red threeawn, and undesirable forbs increase.
