SUMMARY: This study consists of a percolation test, visual inspection of soil strata, record data review and water test for DBCP and Nitrates. The purpose is to determine if the soil strata will support a single family residence of unknown size in the area of on-site septic disposal,with no adverse environmental/health impact(s). PLANNED DEVELOPMENT A Tentative Parcel Map has been prepared which will subdivide the 10 Acre parcel into two 5 acre parcels. Parcel 1 has been developed and contains a SFR,horse barn,hay barn, existing well and on-site septic system. Parcel 2 is vacant of any structures and has been used for pasture and horse training. Parcel 2 will require an on-site septic system and a domestic well. Access for both parcels is Jahant Road.. Jahant Road is a two lane paved County Road. The parcel to the south is 24 acres of basically pasture. On the east is a 8 acre,residential parcel and a new home under construction,to the west a 9 acre parcel and a recently constructed large residence. The area to the north is subdivided into 5 acre parcels. The site is not in the FEMA 100 year flood zone, according to the map. SITUS CONDITIONS The USGS Map compiled from aerial photographs taken 1967-1968 is included in this report and shows no structures or development on the site. The surface drainage is from NE to SW in general. The intersection of Elliott Road and Jahant Road, as shown, is the beginning of a small drainage swale to the NW. Surface drainage does not appear to be a problem at the site. The Map Lchanges oto inspected from 1990 source and as stated on the Map no major culture or drainage were observed.The 1983 aerial photograph obtained from the S.J. County Surveyor's hows the SFR and outbuildings as constructed in 1974. The 10 acre parcel is seen as �c WATER TESTS LN e existing well was tested by Far West Labs,Inc., of Riverbank, California for DBCP and rates. The test report is included and is satisfactory. SOIL CHARACTERISTICS The USDA, Soil Conservation Service published soil data lists the soil type as San Joaquin- Bruella,and in part is described as follows: Where this unit is used for homesite development, the main limitations are depth to the very slowly permeable claypan, depth to the hardpan,the high shrink-swell potential, and low strength in the subsoil. //to
