GEOCHECK'9 - PHYSICAL SETTING SOURCE SUMMARY <br /> DOMINANT SOIL COMPOSITION IN GENERAL AREA OF TARGET PROPERTY <br /> The U.S. Department of Agriculture's(USDA) Soil Conservation Service(SCS)leads the National Cooperative Soil <br /> Survey(NCSS)and is responsible for collecting, storing, maintaining and distributing soil survey information <br /> for privately owned lands in the United States.A soil map in a soil survey is a representation of soil patterns <br /> in a landscape. The following information is based on Soil Conservation Service SSURGO data. <br /> Soil Map ID: 1 <br /> Soil Component Name: SAN JOAQUIN <br /> Soil Surface Texture: sandy loam <br /> Hydrologic Group: Class D-Very slow infiltration rates. Soils are clayey, have a high <br /> water table,or are shallow to an impervious layer. <br /> Soil Drainage Class: Moderately well drained. Soils have a layer of low hydraulic <br /> conductivity,wet state high in the profile. Depth to water table is 3 <br /> to 6 feet. <br /> Hydric Status:Soil does not meet the requirements for a hydric soil. <br /> Corrosion Potential-Uncoated Steel: MODERATE <br /> Depth to Bedrock Min: >0 inches <br /> Depth to Bedrock Max: >0 inches <br /> Soil Layer Information <br /> Boundary Classification <br /> Layer Upper Lower Soil Texture Class AASHTO Group Unified Soil Permeability Soif Reaction <br /> Rate(in/hr) (pH) <br /> 1 0 inches 13 inches sandy loam Silt-Clay COARSE-GRAINED Max: 2.00 Max: 6.50 <br /> Materials(more SOILS,Sands, Min: 0.60 Min: 5.60 <br /> than 35 pct.
