INTRODUCTION Mr. John DeMichelis is creating five parcels and a designated remainder from an existing 269 acre (approximate)parcel which has been owned by the DeMichelis family for several decades. The attached Parcel Map produced by R. B. Welty& Associates illustrates the proposed Parcels indicated as Parcel 1, 2, 3,4, 5 and the Remainder of 46.0 acres. According to the San Joaquin County Development Title, a Surface and Subsurface Contamination Report(SSCR)must be conducted at the time of 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." This investigation addresses and evaluates non-point sources of hazardous materials, as well as potential point sources. Non-point sources include agricultural chemical residues,high concentration of nitrate laden groundwater and other contaminants which may have originated from a wide area or volume. Point sources investigated include fuel storage tanks, septic systems and/or chemical storage areas. No chemical analysis was conducted for this investigation nor was there an inspection of the existing buildings for asbestos containing materials (ACMs). An analysis of the domestic well serving the house on proposed Parcel 1 must be tested for nitrates and the agrichemical dibromochloropropane (DBCP) in a Soil Suitability Study. A Suitability Study will be required by the County Environmental Health Department as stipulated in the Conditions of Approval. SITE DESCRIPTION Illustrated on the attached map, the subject property consists of a irregular shaped, flat, 269 acre parcel. The site is bordered to the north by Avena Road and a dairy facility, and to the east, west, and south by farmland. It is currently zoned A-2-40. The county soil map for the region illustrates a Jack Tone clay soil for the majority of the property. Also included in the Appendix is pertinent information regarding this soil type. The property, and the entire region has been dry land and irrigated farmed for the last several decades. The subject property was has been in tomatoes as evidenced by the attached "Pesticide Treatment and Crop History" reports. It is our understanding there was a small on-site dairy many years ago. There is a single family residence, barn and outbuildings for a total of four buildings in the north center of the property. An on-site domestic well and septic systems serves this and the other mobile home residence. Storm water drainage is managed on-site along the property lines. 1 Vaffey Ag Ppearch
