LJanuary 9,2002 <br /> NOA ENVIRONMENTAL PROJECT NUMBER LE01416 <br /> Typically, the upper part of the surface layer is strong brown gravelly loam about 7 <br /> inches thick... In some areas the surface layer is gravelly sandy loam, cobbly loam, <br /> or loam. <br /> L Included in this unit are small areas of Bellota and Pardee soils on terraces and <br /> shallow, medium textured soils that have a claypan at a depth of 10 to 15 inches and <br /> are in landscape positions similar to those of the Redding soil. Also included are small <br /> areas of Alamo and Yellowlark soils in drainageways, Pentz soils on the slightly <br /> higher terraces, Peters soils in the slightly lower landscape positions, and Redding <br /> soils that have slopes of 2 to 8 percent and are on toe slopes. Included areas make <br /> Lup about 15 percent of the total acreage. <br /> ... Runoff is medium or rapid, and the hazard of water erosion is moderate or severe <br /> (USDA, p.103). <br /> 1. <br /> The following soil description has portions of Redding soils included. For information on these <br /> Lcomponents see above, only new information will be included below. <br /> 135--Corning-Redding complex, 2 to 8 percent slopes. These undulating and <br /> Lgently rolling soils are on the convex side slopes of terraces, commonly on the upper <br /> part of the slopes. The native vegetation is mainly annual grasses and £orbs... <br /> This unit is 45 percent Corning gravelly loam. The components of this unit occur as <br /> areas so intricately intermingled that it was not practical to map them separately at the <br /> scale used. <br /> Included in this unit are small areas of Redding soils that have slopes of 0 to 2 percent <br /> and are on toe slopes, Yellowlark soils in the slightly lower landscape positions, and <br /> gravelly soils that have a claypan and a hardpan at a depth of 40 to 60 inches. The <br /> gravelly soils are in landscape positions similar to those of the dominant Corning and <br /> Redding soils. Also included are Corning and Redding soils alat have slopes of 8 to <br /> 20 percent and small areas of soils that are similar to the Corning soil but are <br /> underlain by consolidated sediments at a depth of 30 to 60 inches. Included areas <br /> make up about 15 percent of the total acreage. <br /> ... Typically,the surface layer is light brown, yellowish red, and light brown gravelly <br /> loam about 21 inches thick... <br /> Permeability is very slow in the Coming soil. Available water capacity is moderate... <br /> Water is very briefly perched above the claypan after periods of heavy rainfall or <br /> 6 <br /> L <br />
