The unit is composed of alluvial <br /> floodplain deposits (see Plate 5). <br /> The surface and near surface soils located at the Site are reported by the San Joaquin County <br /> Soil Survey to be composed of Columbia fine sandy loam, Dello clay loam, Egbert silty clay <br /> loam, Merrit silty clay loam and Scribner clay loam, all 0-2% slopes (see Plate 6) (USDA, 1992). <br /> The table below presents some selected properties of these soils: <br /> Table 1 <br /> San Joaquin County Soil Survey <br /> Elected Soil Properties of On-Site Soils <br /> Soil Name Depth Salinity Soil Perme- Septic tank <br /> and Map Unified Soil Classification mmhos Reaction ability absorption <br /> Symbol (�n) /cm pH (in/hr) fields <br /> Columbia, 0-12: Fine sandy loam; SM, SC-SM <2 6.1 - 7.8 2.0 - 6.0 Moderate:flooding, <br /> 130 m <br /> 12-60: Stratified sand to silt loam; SM <2 6.1 - 7.8 2.0 - 6.0 peres, slowly <br /> 0-20: Fine sandy loam; SM, SC-SM <2 6.1 - 7.8 2.0 - 6.0 Severe: <br /> Columbia, 20-48: Fine sandy loam, sandy loam; <2 6.1 - 7.8 2.0 - 6.0 wetness, <br /> 133 SM, SC-SM percolates <br /> 48-60: Clay loam, silty clay loam, clay. <2 6.6 - 8.4 0,06 - 0.2 slowly <br /> 0-12: Clay loam; CL <2 6.6-8.4 0.2-0.6 Severe: poor <br /> Dello, 148 filter <br /> 12-60: Sand, fine sand; SM, SP-SM <2 6.6-8.4 6.0-20 <br /> 0-14 Silty clay loam; CL, ML <2 6.1-7.8 0.2-0.6 <br /> Severe: <br /> Egbert, 154 14-40 Silty clay loam; CL, CH <2 6.1-7.8 0.06-0.2 wetness, <br /> 40-60 Stratified loamy fine sand to <2 7.4-7.8 6.0-20 poor filter <br /> sand; SM <br /> Merritt silty 0-17: Silty clay loam, CL <2 6.6-8.4 0.2-0.6 <br /> clay loam, Severe: <br /> partially 07-49: Silt loam, silty clay loam, CL <2 7.9-8.4 0.2-0.6 percolates <br /> drained, 0-2 19-60: Stratified loamy fine sand to silt <2 7.9-8.4 0.6-2.0 slowly <br /> slopes, loam, SM, ML <br /> 197 <br /> Scribner clay <br /> L <br /> , 0-24: Clay loam; CL <2 6.1 - 7.8 0.2 - 0.6 Severe: <br /> lly wetness, <br /> , 0- 24-60: Stratified loam to silty clay loam; <2 6.6 - 8.4 0.2 - 0.6 percolatpes, CLslowly <br /> Note: The table descriptions do not necessarily reflect site-specific soil properties. <br /> * See description of the map unit for composition and behavior characteristics of the map unit <br /> 902 Industrial Wa% -Lodi.CA 95240-209.367.3701 - Fax 209.369.4228 c,'00N 1 ed 0 Anderson&Associates. bec <br />
