<br /> LThe surface and near surface soils located at the Site are reported by the San Joaquin County Soil Sunny
<br /> to be composed of Itano silty clay loam, 0-2% slopes, Rindage mucky silt loam,partially drained,
<br /> L0-2% slopes,Rindge muck,partially drained, 0-2%slopes, Ryde clay loam,partially drained, 0-2%
<br /> slopes, and the Venice mucky silt loam,partially drained,0-2% slopes (Plate 3) (USDA, 1992).
<br /> Table 3 presents some selected properties of the soils:
