Soil Suitability Study**MS-01-01**APN: 255-100-07**3Parcels,Each 43.67 Acres"139.11 Acres Total One (1)of the three(3)the septic permits classified the soil as sandy loam. The remaining two(2) septic permits did not contain any soil classification. SOIL PROFILE TEST: No water was encountered in excavating the Soil Profile Test Hole to a maximum ash nf_12'f14" feet_See the attached"Field Percolation Data Sheets",the attached "Tentative Par Map"and the tent of this report as well, for the specific soil layers character and test hole location details. On the "Field Percolation Data Sheet" included in this report I have noted the soil encountered to be a gray clay to a depth of 2' below the ground surface. Between 2' and 12'04" below the ground surface I have noted the soil to be a reddish brown, silty clay. The University of California publication entitled"Soils of San Joaquin County, California by Walter W. Weir, dated June 1952", refers to the soil in this general area as being a Sorrento Silty Clay classification, consisting of a gray clay in the top two(2) feet and a brown in color silty clay in the next four(4)feet to six(6) feet strata with good surface and imperfect subsurface permeability. The soil is on a level to 2% slope and has a no surface erosion classification. The soil has a Storie Index of 65 that makes it a good soil for growing agricultural crops. The"Soil Survey of San Joaquin County, California,United States Department of Agriculture Soil Conservation Service" issued October 1992 lists the soil type in this general area as Capay clay, wet, level to 2% slope. It is very deep and well drained. The surface Iayer is grayish brown and dark grayish brown in color and twenty(20) inches thick. From twenty(20)to sixty(60) inches below the ground surface the soil becomes a silty clay loam and pale brown in color. The soil is mostly used for irrigated crops or orchards and has a high shrink-swell factor. The percent of clay present and the permeability at various depths below the ground surface are listed as follows: Depth (Inches) Percent Clay Permeability(In./Hr.) 0 - 20 40 -60 0.06 -0.20 20 - 44 40-60 0.06-0.20 44 -60 35 -40 0.06 -0.20 The San Joaquin County Flood Control and Water Conservation Map entitled "Lines Of Equal Depth To Water Wells", dated Spring 1999, does not contain any contour lines to indicate any specific depths of the ground water below the existing ground. The nearest contour line to the east of the subject property shows the water table to be in excess of ten(10) feet below the ground surface. Michael M.
