Soil Profile and Geologic Information The Site is depicted on the Geologic maps of the Sacramento-San Joaquin Delta, California (Atwater, 1982). The Site is depicted within a map unit of Holocene alluvial- floodplain deposits (Plate 11). The surface and near surface soils located at the Site are reported by the USDA Web Soil Survey to be composed of Egbert silty clay loam and Merritt silty clay loam (Plate 12) (USDA, 2020). The table below presents some selected properties of these soils: Table 1.
