Exhibit I <br /> Soils Information <br /> The soils on this site are described using the following; a) Soil Survey of Chaffee-Lake <br /> County. The soils of the affected area are Ouray Gravelly Loam and San Isabel Stony <br /> Sandy Loam. <br /> Ouray series, thick surface variant, consists of deep, well-drained soils on terraces. These <br /> soils formed in noncalcareous, stratified,moderately coarse textured and medium- <br /> textured alluvium. Slopes range from 1 to 3 percent. Average annual soil temperature is <br /> 46°F., and the average soil temperature in summer is 64°F. In a representative profile, <br /> the surface layer is very dark brown gravelly loam and fine gravelly sandy loam and very <br /> dark grayish-brown loam about 26 inches thick. Permeability in these soils is moderate, <br /> and the available water capacity is moderate. Runoff is slow on this soil, and the hazard <br /> of erosion is slight. Most of the acreage is irrigated and used for crops with effective <br /> rooting at a depth of 60 inches or more. <br /> San Isabel series consists of somewhat excessively drained soils on high terraces. These <br /> soils are shallow over gravel and cobbles. They formed in gravelly,moderately coarse <br /> textured outwash. Slopes range from 1 to 5 percent. The plant cover is bunchgrasses. <br /> Average annual soil temperature is 46°F., and the average soil temperature in summer is <br /> 64°F. In a representative profile, the surface layer is very dark grayish-brown stony <br /> sandy loam about five inches thick. The subsoil is dark-brown gravelly sandy loam about <br /> 14 inches thick. The substratum is gravel, cobbles, and boulders. The profile is neutral <br /> throughout. Permeability in these soils is rapid and the available water capacity is low. <br /> Surface runoff is slow and the hazard of erosion is slight. Most of the acreage of this soil <br /> is in native grass and is used for grazing of livestock and winter feed for wildlife and has <br /> an effective rooting depth of 60 inches or more. <br /> I-1 <br />
