"Soil suitability Study";Diamond Crest Estates Subdivision,Parcel 1 =43.10 Net Acres,With Access Off <br /> Of A Dirt Road Off Of Kasson Road, APN:255-34-07 <br /> SOIL PROFILE: The University of California publication entitled"Soils of San Joaquin <br /> County, California",by Walter W. Weir, dated June 1952, refers to the soil type on this <br /> subject property as being"Rincon Clay Loam", brown in color. The permeability on the <br /> subject property is good surface and subsurface drainage. The soil is listed as being on an <br /> almost level slope (0%to 2%) and has a pH=7.7 and is subject to little erosion. The <br /> Storie Index is 72, which makes the soil good for growing crops like beans,tomatoes, <br /> alfalfa and some fruits. This soil is found in alluvial fans and developed from <br /> sedimentary rock sources. Generally,the soil consists of 24 % sand, 37% silt and.39% <br /> clay. The color of the soil at various levels below the ground surface is listed as follows: <br /> DEPTH In Inches COLOR <br /> 7 to 14 Brawn/Brownish Gray <br /> 14 to 30 Brown/Dark Brown <br /> 30 to 36 Light Brown <br /> 36 to 60 Yellowish Brown <br /> The University of California publication entitled"Soils of San Joaquin County, <br /> California,United States Department of Agricultural Soil Conservation Service", issued <br /> October 1992, lists the soil type on the majority of the subject property as Capay Clay <br /> and a very small area as Capay Clay, Saline. Basically the soils are the same except for a <br /> higher salt content for the Capay Clay, Saline classification so only the Capay Clay <br /> classification soil is discussed in detail in this report as follows: <br /> Capay Clay is a very deep and wet soil on a 0%to 2% slope. The soil is of alluvial <br /> derivation from mixed rock sources with a high water table as a result of irrigation water. <br /> It is at elevations from 25 feet to 140 feet, in a climate with annual rainfall of ten(10) <br /> inches and average temperature of 60 degrees Fahrenheit with 270 frost-free days. The <br /> soil has a high shrink-swell factor and permeability is generally slow and the available <br /> water capacity is high. <br /> The soil color of the soil below the ground surface at various depths are listed as <br /> follows: <br /> " DEPTH(In Inches) COLOR <br /> 0 to 20 Grayish Brown/Dark Grayish Brown/ Dark Brown <br /> 20 to 60 Pale Brown <br /> The percent of clay, soil type, plasticity index, permeability and density at various <br /> depths below the ground surface are listed as follows: <br /> DEPTH SOIL TYPE PLASTICITY PERMEABILITY %CLAY DENSITY <br /> In Inches) INDEX (Inches/Ho (Grams/cc <br /> 0 to 20 Clay 20-35 1.30-1.50 40 -60 0,06-0.2 <br /> 20 to 44 Clay/ Silty Clay . 20 -35 1.35 -1.50 40 -60 0.06-0.2 <br /> 44 to 60 Silty Clay Loam/ 15-25 1.40-1.50 35-40 0.06-0.2 <br /> Clay Loam <br /> Lisa.Ward, 1034 Central Ave.,Tracy, California 95376—3915,(800) 836-1404,(209)836-1404 <br /> Z <br />
