01 July 2016 AGE Project No. 15-3403 Page 11 of 12 type for the subject property as caypay clay, 0 to 2 percent slopes (#107). The caypay clay has been denoted as shallow to 60 inches deep and percolates slowly. Permeability is slow in caypay clay and the soil has a high shrink-swell potential. Caypay clay soil typically has the same chemical properties between 0-60 inches bsg. The pH level ranges between 6.6 - 7.3 units with a salinity of less than 2.0. 9.2. MASS TRANSPORT PROPERTIES OF UNDERLYING SITE SOILS This shallow well-drained rich soil has a high available water-holding capacity. Additionally, three feet deep septic leach pits should be installed at the ends of the septic leach filed lines. The natural fertility of this soil lends it very well to sustainable farming practices. Permeability is slow, available water capacity is high and the shrink-swell potential is high. Septic leech fields should have an increased absorption field to overcome the slow permeability. 10.0. DESCRIPTION OF LOCAL GROUNDWATER The San Joaquin County Flood Control and Water Conservation District's Lines of Equal Depth to Groundwater Fall 2012 indicates the depth to groundwater is 5 to 10 feet bsg. Groundwater appears to flow to the northeast in the direction of the San Joaquin River. AGE performed a groundwater query on the California Department of Water Resources (CDWR) Internet site, http://well.water.ca.gov. Based on the CDWR the current depth to groundwater surrounding (within one mile) the subject property was 10 feet bsg. Based upon a record review conducted at EHD by an AGE representative depth to water was indicated on well permits for the surrounding area to be at 10 feet bsg. The wells on the adjacent properties were sealed to a depth of 50 feet at most south Borba Road permitted properties. 10.1. EXISTING OR POTENTIAL GROUNDWATER CONTAMINATION The immediately adjacent and outlying land use for the parcel is agricultural in nature. There are potential groundwater contamination issues associated with agricultural uses and septic systems. A review of the DTSC Envirostor/Geotracker Database revealed one LUST site within a two-mile radius of the site. The site has been closed for more than 10 years and is located more than one-mile from the subject parcel. 10.2. CURRENT AND FUTURE USE OF GROUNDWATER AT THE SITE The newly installed water supply well conforms to DWR and EHD standard and will be used to supply the domestic (including the proposed multi use buildings) uses at the property Advanced Gec,Enviconmen[al,Inc.
