Lange Property Page 5 <br />Our Project Number: LGS080011 <br />February 28, 2008 <br />V45.0 SOIL PROFILE AND GEOLOGIC INFORMATION <br />The Site is depicted on the USGS Preliminary Geologic Map of San Francisco - San Jose <br />Quadrangle as within the Quaternary Riverbank Formation. Quaternary Riverbank Formation - <br />weathered reddish gravel, sand, and silt forming clearly recognizable alluvial terraces and fans <br />(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 Bruella sandy loam and San Joaquin Loam, 0-8 % slopes (Plate <br />6) (USDA, 1992). The table below presents some selected properties of these soils: <br />Table 1. <br />San Joaquin County Soil Survey <br />Selected Soil Properties of On -Site Soils. <br />Soil Name <br />Depth <br />Salinity <br />Soil <br />Perme- <br />Septic tank <br />and Map <br />(�n) <br />Unified Soil Classification <br />(mmhos/ <br />Reaction <br />ability <br />absorption <br />Symbol <br />cm) <br />pH <br />(in/hr) <br />fields <br />Bruella <br />0-18: <br />Sandy loam; SC -SM, SM <br /><2 <br />6.1-7.3 <br />2.0-6.0 <br />Severe: <br />sandy <br />18-31: <br />Sandy clay loam, sandy <br /><2 <br />6.1 - 7.3 <br />0.2-0.6 <br />peres slowly <br />loam, 0-2 <br />31-67: <br />loam; SC <br /><2 <br />6.1-7.3 <br />0.2-0.6 <br />% slopes, <br />Sandy clay loam, clay loam; <br />111 <br />SC, CL <br />San <br />0-16 <br />Loam; CL -ML, ML <br /><2 <br />5.6-6.5 <br />0.6-2.0 <br />Severe: <br />Joaquin <br />16-26 <br />Clay loam, clay; CL <br /><2 <br />6.1-7.8 <br /><0.06 <br />cemented <br />238 <br />26-60 <br />Indurated <br />--- <br />--- <br />--- <br />pan, peres <br />slowly <br />San <br />See <br />See 238 <br />See 238 <br />See 238 <br />See 238 <br />Severe: <br />Joaquin <br />238 <br />cemented <br />239 <br />pan, peres <br />slowly <br />San <br />0-12: <br />Loam; CL -ML, ML <br /><2 <br />5.6-6.5 <br />0.6-2.0 <br />Severe: <br />Joaquin <br />12-26: <br />Sandy clay loam; SC <br /><2 <br />6.1 - 7.3 <br />0.2-0.6 <br />cemented <br />loam, thick <br />26-35: <br />Clay loam, clay; CL <br /><2 <br />6.1-7.8 <br /><0.06 <br />pan, peres <br />surface, 0- <br />35-60: <br />Indurated <br />--- <br />--- <br />--- <br />slowly <br />2% slopes <br />240. <br />/1.1 Soil Boring Locations <br />A total of six (6) soil borings were advanced on the Site to depths of approximately three and a <br />half feet. The soil borings were used later for percolation test holes; the locations of the borings <br />are indicated in Plate 1. <br />902 Industrial Way • Lodi, CA 95240. 209.367.3701 - Fax 209.369.4228 *2008 Neil 0.Anderson & Associates, Inc <br />
