CINTRODUCTION Mr. Ross Brown is creating a second parcel from property he owns at 9203 East West Ripon Road near Manteca, CA. Parcel 1 is proposed to contain 1.8 acres, which is less than the required 2.0 acres. A variance was granted by the San Joaquin County Board of Supervisors to allow this 1.8 acre Parcel. The purpose of this project is to create this small homesite parcel, which is separate from the remaining property. Mr. & Mrs. Harvey and Grace Kelley will occupy this smaller, second Parcel. According to the San Joaquin County Development Title, a Surface and Subsurface Contamination Report(SSCR)must be conducted prior to Tentative Map submittal. The purpose of this report was to investigate the subject property for real or potential environmental contamination and report the findings to the Client and the San Joaquin County Environmental Health Department. This report complies with the San Joaquin County Ordinance, specifically 9-905.12(a) for a "Surface and Subsurface Contamination Report." In addition, this report addresses and evaluates non-point sources of hazardous materials, as well as potential point sources. Non-point sources of hazardous materials include agricultural chemical residues, potential for nitrate impact to the underlying groundwater and other contaminants which may have originated from a wide area. Point sources investigated include fuel storage tanks, septic systems and/or chemical storage areas. No chemical analysis was conducted for this investigation. Additionally, since there was no building scheduled to be demolished, the existing structures were not inspected for asbestos containing materials (ACMs). An analysis of the domestic well serving the house on proposed Parcel 1 (9203 E. West Ripon and the Designated Remainder (9333 E. West Ripon) was tested for nitrates and the agrichemical dibromochlorpropane (DBCP) for the Soil Suitability Study, which was completed on January 4, 2001. The test results are discussed below. SITE DESCRIPTION As illustrated on the attached Tentative Map, Parcel 1 and Parcel l consists of a flat, rectangular shaped acres. The subject site address and A.P.N. are referenced above. Parcel 2 is denoted as the Designated Remainder and is currently planted in almonds. Parcel I contains a single family residence that was built around 1910 - 1915, an agricultural barn type building and a well "pump house" that is no longer used. The site is bordered to the north, south, east and west by agricultural production land, including primarily almond orchards, pasture, and low density single family housing. The property is currently zoned AG 40. The subject property is not in the 100 year flood plain. 1 va!&ey Ag Research
