7runderstandinrg d in the southwest comer of Greenwood Avenue and McCracken Road. It is our at the property is not subject to the 100-year flood;however, this should be d Surveyor. ocated east of the town of Vernalis and directly east of Highway 33 and Interstate 5. Surrounding land use consists predominately of agricultural production land-primarily row crops and pasture land. Surrounding structures consist of very low density single family housing, residential ranchettes, barns and related agricultural facilities such as the Wester Farm Service facility to the southwest of the subject property. Sewer hookups to a Publically Operated Treatment Works (POTW), or municipal treatment plant will probably never occur. A review of Application Permits on file with the San Joaquin County Environmental Health Department shows there have been two Applications for Repairs/Additions on the subject property and no Applications for Repairs/Additions to septic systems within the one-half mile radius study area. Since the water table is shallow in this area, seepage pits or sumps are not allowed. Mr. Bogetti stated that to his recollection,there has never been a serious problem with any of the on-site septic systems. The lack of septic system repairs and additions within the study area may be attributable to the extremely low density housing. Located in the Appendix, are all of the permits that were on file for the on-site septic systems, and well/well pump repairs and installations. A Well Driller's Log for the on-site, or nearby domestic wells were not available, so the underlying strata are unknown. SOIL PROFILE AND PERCOLATION TESTING The United Stated Geological Survey(USGS)Map indicates the subject property to range from 80 feet MSL in the southwest corner of the property to 60 feet MSL in the northeast corner. The United States Department of Agriculture (USDA)Natural Resources Conservation Service (formerly the Soil Conservation Service) soil maps illustrate the subject property soils to be entirely composed of a Capay Clay(#121). Information provided in the Soil Survey reveals the soil is very deep and moderately well-drained, and has a high water table as a result of the application of irrigation water. Permeability is slow and available water capacity is high. From two backhoe test pits described below,the soil profile was easily distinguished and correlates with the descriptions as found in the Soil Survey. From the surface to approximately three feet is a uniform dark brown clay, with little sand and silt. There is visible organic matter, and a medium moisture content from recent rains within the soil profile. At three to four feet, there is a distinct calcareous stratum that has white streaks. The remaining soil depth consists of a uniform silty clay. The Unified Soil Classification System (USCS) classifies the soil profile as CL/CH- a lean-to-fat(high plasticity) clay and CL-ML - a silty clay. A Log of Boring designating the USCS soil classification is found near the top right-hand comer of the FIELD PERCOLATION TESTING REPORT. LPage -2- Ckemey Consulting
