It is a unit of <br /> undifferentiated alluvial deposits, mainly arkosic, forming the toe of the Mokelumne alluvial fan, <br /> generally covered by 0.3 to 1.0 In of Holocene intertidal deposits (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 Jacktone clay and Manteca fine sandy loam, both 0-2% slopes ' <br /> (Plate 6) (USDA, 1992). 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 /> Jacktone 0-22 Clay; CL, CH <2 6.6-8.4 0.06-0.2 Severe: <br /> clay, 0-2 % 22.34 Clay loam, clay silty clay; CL, <2 7.9-9.0 0.06-0.2 cemented pan, <br /> slopes, 180 CH percs slowly <br /> 34-37 Indurated <br /> 37-46 Loam, clay loam; CL-ML, CL <2 7.9-9.0 0.2-0.6 <br /> 46-60 Cemented <br /> Manteca fine 0-11 Fine sandy loam; SM <2 7.4-8.4 2.0-6.0 Severe: <br /> sandy loam, 11-24 Sine sandy loam, loam, sandy <2 7.4-8.4 0.6-2.0 cemented pan / <br /> 0-2 % loam; SM, SC-SM <br /> slopes, 196 <br /> 24-35 Indurated <2 ___ --- <br /> 35-54 Cemented <2 --- --- <br /> 54-74 Stratified loamy sand to loam; <2 7.4-8.4 2.0-6.0 <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 /> 5.1 Soil Boring Locations <br /> A total of one (1) soil boring was advanced on the Site to a depth of approximately three and a / <br /> half (3.5) feet. The soil boring was used later for a percolation test hole; the location of the <br /> boring is indicated in Plate 1. <br /> 5.2 Soil Boring Dimensions <br /> The soil boring was approximately three and a half (3.5) feet, as noted above, and was four (4) <br /> inches in diameter. <br /> 902 Industrial Way•Lodi,CA 95240-209.367.3701 •Fax 209.369.4228 02008 Neil O.Anderson&Associates,Inc <br />
