~.4.9 EXHIBIT I -Soils luformatio• <br />The affected area lies at an elevation of 6,520 feet and has slopes ranging from nearly level to <br />12%. The area was mapped by the USDA Soil Conservation Service (SCS now NRCS). <br />Descriptions given below are based on an adaptation of the available NRCS data. A soils map <br />showing the general delineation of the soils present in the permit area follows this section. <br />The Dry Bodot/Dry Zyme soil type is present across most [o the proposed disturbed area. A <br />smaller section ofGladel-Bond-Rock Outcrop soil type is distributed over the outcrop of the <br />gravel bed itself. Avery small portion of the Vananda soil type may occur along the soutlrem end <br />of the gravel outcrop, but is more likely found just below the outcrop. Other portions of the <br />permit area include Dry Bodot, Dry Bodot/ Dry Zyme and Gladel-Bond-Rock Outcrop soil types. <br />These soil types are described as follows: <br />14 - Bodot-Zyme silty clay loams, Dry, 3 to 20 perceut slopes. (Publication Symbol 24) <br />This map unit is 45 percent Daick soil and 40 percent Perysayo soil. The Bodot soil is <br />moderately deep and well drained on hills and ridges. It formed in residuum from shale. <br />Typically, the surface layer is silty clay loam 3 inches thick. The upper 15 inches of [he <br />underlying material is silty clay. The lower part to a depth of 38 inches is silty clay loam. <br />Permeability is slow and the available water capacity is moderate. Surface runoff is <br />medium to very rapid and the hazard of water erosion is slight to very high. The effective <br />rooting depth is 20 to 40 inches. <br />The Zyme soil is shallow and well drained on hills and ridges. I[ formed in residuum from <br />shale. Typically, [he surface layer is silty clay loam 6 inches [hick. The underlying <br />material to a depth of 15 inches is clay loam. Permeability is slow and the available water <br />capacity is very low. Surface runoff is medium to very rapid and the hazard of water <br />erosion is slight to very high. The effective rooting depth is 10 to 20 inches. <br />Land Capability Unit NIRR 6e, IRR 6e <br />35 -Gladel-Bond-Rock Outcrop complex, 1 to 50 perceut slopes. (Publicatiou S}'mbo145) <br />This map unit is 35 percent Gladel soil, 30 Percent Bond soil and 30 percent Rock <br />Outcrop. The Gladel soil is shallow and well drained on mesas, benches, and <br />escarpments. It formed in residuum from sandstone. Typically, the surface layer is sandy <br />loam 4 inches thick. The underlying material to a depth of 8 inches is sandy loam. <br />Permeability is moderately rapid and [he available water capacity is very low. Surface <br />runoff is slow to very rapid and the hazard of water erosion is slight to very high. The <br />effective rooting depth is 8 to 20 inches. <br />The Bond soil is shallow and well drained on mesas, benches, and escarpments. I[ formed <br />in residuum from sandstone. Typically, the surface layer is fine sandy loam 3 inches thick. <br />The subsoil to a depth of 16 inches is sandy loam. Permeability is moderate and the <br />available water capacity is very low. Surface runoff is slow to very rapid and the hazard of <br />water erosion is slight to very high. The effective rooting depth is 10 to 20 inches. <br />Rock Outcrop consists of large exposures of bedrock <br />Land Capability Unit NIRR 6e, IRR 6e <br />I-1 <br />
