V- <br /> October 22,2002 <br /> NOA ENVIRONMENTAL PROJECT NUMBER LE02-386 <br /> 203--Pardee cobbly loam, 3 to 15 percent slopes. This shallow, well drained, <br /> undulating to rolling soil is on hills. It formed in cobbly and gravelly alluvium derived <br /> ` from mixed rock sources and is underlain by andesitic, tuffaceous conglomerate. <br /> Slopes are convex, and the landscape is characterized by hummocky microrelief. <br /> Gravel and cobbles cover 15 to 50 percent of the surface in small concave areas and <br /> ` commonly 3 to 15 percent of the surface in convex areas. <br /> Typically, the surface layer is yellowish red cobbly loam about 9 inches thick. <br /> Permeability is moderately slow in the Pardee soil (USDA, p. 92). <br /> 219--Redding loam, 0 to 3 percent slopes. This moderately well drained, nearly <br /> level gently sloping soil is on high terraces. It is moderately deep to a hardpan. It <br /> formed in alluvium derived from mixed rock sources... Meandering drainageways and <br /> �- closed depressions fill with water to form vernal pools during the winter in many <br /> areas. <br /> L Typically,the upper part of the surface layer is light brown loam about 6 inches thick. <br /> In some areas the surface layer is gravelly or cobbly loam. <br /> ` Permeability is very slow in the Redding soil (USDA, p.101,102). <br /> 220—Redding gravelly loam,2 to 8 percent slopes. This moderately well drained, <br /> ` undulating and gently rolling soil is on high terraces. It is moderately deep to a <br /> hardpan. It formed in alluvium derived from mixed rock sources. Meandering <br /> drainageways and closed depressions fill with water to form vernal pools during the <br /> winter in many areas. <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 /> Permeability is very slow in the Redding soil (USDA, p.102). <br /> 279--Yellowlark gravelly loam, 0 to 2 percent slopes. This moderately well <br /> drained, nearly level soil is on stream terraces. It is deep to a hardpan. It formed in <br /> alluvium derived from mixed rock sources... Meandering drainage ways and closed <br /> depressions fill with water to form vernal pools during the winter in some areas. <br /> _ <br /> 6 <br />
