PROPERTY DESCRIPTION: Portion Sec. 15, T. 4 N. R. 7 E, Calif. Village Farm Tract. Subd. "E"APN 007-07-29 10 Acres. SUMMARY OF PURPOSE This Soil Suitability Study presents the results of physical testing and inspection to determine if the soil strata,to 251,will support an onsite septic system for a single family residence.. Percolation testing, water testing and visual inspection were conducted. The procedures comply with the requirements of the Environmental Health Department of San Joaquin County. DEVELOPMENT OF THE SITE The existing parcel is to be split into two parcels. Parcel 2 is developed and contains a single family residence, a bam, metal building and supporting utilities. (Well & septic). The new parcel is vacant, (Parcel 1). Parcel 1 is to be sold. Access is from Sowles Road for both parcels. Sowles Road carries both passenger and local truck traffic. DESCRIPTION OF SOIL TYPE The USDA Soil Survey of San Joaquin County(Unit#111) states in the descriptive narrative, page 32,the following:If this unit is used for homesite development, the main limitation is the moderately slow permeability. On sites for septic tank absorption fields, this limitation can be overcome by increasing the size of the absorption field Drilling to 25' to determine a percoble layer indicated 0-3' tan dense clay, 3'-5' darker clay, 5'-10' moist clay, 10'-13' wet clay,and dense dry clay 13'-25'. PERCOLATION TESTING Percolation testing began on July 19,2002. A truck mounted drill rig was employed to auger a shallow and deep hole on each of the two parcels. From visual inspection and drilling difficulty it was determined between 6 and 7 feet would be tested forAe deep t=c. The shallow holes were 36-42" deep. Again on Aug. 19, 2002 both lots were again tested. Mr. Walt Curtis,a Civil Engineer licensed in the State of California performed the testing. Mr. Johnny Yoakum,R.E.H.S. of the Environmental Health Department, County of San Joaquin was present for the critical readings. The testing procedure was in accordance with the EHD, Standards& Policies as published. The testing on July 19 on Parcel l (developed parcel) failed at both the shallow and deep holes. The testing on Parcel 1 (vacant parcel)failed at the deep test. The shallow test indicated questionable readings. The final reading of 5/8" was satisfactory. An additional reading was made 30 minutes after the testing period ended and read 3/8". The readings were made with a battery operated water surface detector,which required visual reading of the depth on the tape. The additional testing on Aug. 19 resulted in failure of all tests on both parcels.
