01 July 2016 AGE Project No. 15-3403 Page 3 of 12 not been completely defined but are believed to be of metamorphic and igneous origins. Northern and southern portions of the Great Valley Province have been designated the Sacramento and San Joaquin Valleys, respectively. The subject property is located within the San Joaquin Valley. The property is further located within the San Joaquin Valley Groundwater Basin, Tracy Subbasin (5-22.15). The Tracy Subbasin is defined by the areal extent of unconsolidated to semiconsolidated sedimentary deposits that are bounded by the Diablo Range on the west; the Mokelumne and San Joaquin Rivers on the north; the San Joaquin River to the east; and the San Joaquin- Stanislaus County line on the south. The Tracy Subbasin is located adjacent to the Eastern San Joaquin Subbasin on the east and the Delta-Mendota Subbasin on the south. All of the above mentioned subbasins are located within the larger San Joaquin Valley Groundwater Basin. The Tracy Subbasin also lies to the south of the Sacramento Valley Groundwater Basin, Solano Subbasin. The Tracy Subbasin is drained by the San Joaquin River and one of its major westside tributaries, Corral Hollow Creek. The San Joaquin River flows northward into the Sacramento and San Joaquin Delta and discharges into the San Francisco Bay. Estimated depth to groundwater beneath the property is between approximately 10 feet below surface grade (bsg), based on the map titled Lines of Equal Depth to Groundwater Fall 2012 published by the San Joaquin County Flood Control District and Water Conservation District (FCD&WCD). It is inferred from the map titled Lines of Equal Elevation of Groundwater Fall 2012, also published by the FCD&WCD, local groundwater flow is northeasterly towards the San Joaquin River beneath the subject property. Topography The property is located at an elevation of 9 feet above mean sea level (MSL) and in an area of low topographic relief. Regional slope of the area is toward the general west. Surface USDA provides a report listing dominant soil composition in the general area Soils of the subject property based on information from the United States Department of Agriculture's Soil Conservation Service STATSGO (State Soil Geographic Database) soil maps. Soil surface texture is listed as Egbert soil, a clay, in the Class D Hydrogeologic Group which includes very slow infiltration rates. Corrosion potential of this soil for uncoated steel is high. Surface There are no surface water features on the subject property. The nearest Water surface water features in the vicinity of the property is the San Joaquin River, Features located approximately 8,500 feet northeast of the site. Flood Zone The database report shows that the subject property is located within a 100 Flood Zone. The determination is a Zone AE. This data, available in select counties across the country, was obtained from the Federal Emergency Management Agency (FEMA) which has maps depicting FEMA-defined 100- year and 500-year flood zones.
