#12 BALLER-ROCK OUTCROP COMPLEX 15-45%SLOPES VIIS-1 DRYLAND <br /> This complex consists of strongly sloping to steep soils on ridges and "hogbacks". It is about 50% Baller <br /> stony sandy loam and about 30% Rock outcrop.This soil consists of shallow,well drained soils.These <br /> soils are on uplands and are underlain by bedrock at a depth of 10-20 inches. Mean annual precipitation <br /> ranges from 15-17 inches, mean annual air temperature ranges from 47*to 49' F, and the frost-free <br /> season ranges from 135-150 days. <br /> The Surface Layer is dark grayish brown stony sandy loam about 6 inches thick.The subsurface layer is <br /> dark grayish brown very stony sandy loam about 5 inches thick. Below this is hard sandstone. <br /> Permeability is moderately rapid, and the available water capacity is low. Reaction is neutral.These soils <br /> are used for native grasses. Included with this complex in mapping is about 20%Carnero soils and areas <br /> of soils that are similar to the baller but that has a clayey subsoil.The Carnero series consists of <br /> moderately deep,well drained soils. Permeability is moderately slow, and the available water capacity is <br /> medium. Reaction is neutral. <br /> Runoff is medium to rapid,and the hazard of water erosion is moderate to severe. Deep hullies are in <br /> some areas. <br /> This soil is suited to native grasses. Scattered stands of ponderosa pine are in a few areas. <br /> R:\2100\2186.00 Arkins Park_Permit\DOCUMENTS AMENDED PERMIT Exhibit I-Soils Information.docx <br />
