SUMMARY This study completes our analysis of the 3 lot subdivision proposed for the designated site. As indicated in the attached Soil Exploration Report,the terrain in general is not conducive to, standard septic system installation. The San Joaquin County Sewage Standards, dated 11/96 and the San Joaquin Development Title are applicable to this development. The Map should be conditioned to require an engineer designed on-site septic system for Parcels I & 3, and a standard syiiemTor Parcel 2 (Selective location),all to be approved by the Environmental Health Department of San Joaquin County. SITE BACKGROUND INFORMATION The 3 parcels shown on the proposed Parcel Map represent the land utilized for grazing of cattle. The land presently is used for pasture for cattle and has been pasture for over 10 years.The Agricultural Commissioner's Office reported on 8/21/01 negative results for a file check on chemical use by permit. An irrigation well furnishes water to a portion of the land. Some of the land is not sloped for irrigation and is dry pasture. At one time a small earthen dam was constructed across the swale to provide water for the cattle. This dam was removed and the swale drains the runoff irrigation water at present. The swale runs thru the existing parcel from northwest to southeast. A commercial Turkey raising facility exists immediately to the north of Parcel 1 & 2. When the site was first visited, the flies were massive in numbers and the vehicle windows were rolled up to prevent an intrusion of flies. On the second visit the flies were not noticed. It may be related to the manure processing time table. The location of any residence near a manure processing area should expect flies at a certain time. The odor was only observed within approximately 100'of the manure piles. There are numerous"vernal pools", especially on Parcel 2. The conditions of approval of PA-02-3 require certain setbacks from the Swale. The 2002 grass crop was dead as of the final percolation test on June 21. There is extreme danger of starting a fire from any vehicle which traverses the area. The Fish& Wildlife Service commented on Jan. 31, 2002 via letter to Mr. Rick Griffin of the SJCCDD with reference to the ESA, as they believe the property contains vernal pools. As of this date the final conditions is not known by the preparer of this report. GROUNDWATER INFORMATION Groundwater elevation as determined by the San Joaquin County Flood Control and Water Conservation District Maps(1992) show 150 feet on lines of equal depth of water wells for this area. The present well on Parcel 3 was sampled and the report from FGL is attached. The results are satisfactory.(DBCP and Nitrate). SOIL PROFILE AND PERCOLATION TESTING Attention is directed to the summary of the June 21,2002 field observations, contained in the Soil Exploration Report.
