INTRODUCTION Mr. Joseph Bacchetti and his father Frank Bacchetti are creating a second parcel from property they own on South Laurel Avenue in Tracy, CA. 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." It also complies with the standard practice promulgated in the American Society of Testing and Materials, ASTM E1527. In addition, the 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, 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 will be tested for nitrates and the agrichemical dibromochlorpropane (DBCP) in the Soil Suitability Study, which will also be required for this project by the County Environmental Health Department. SITE DESCRIPTION As illustrated on the attached Tentative Map, the subject property consists of an irregular shaped, flat, 53 acre parcel. Site addresses are 20280/20301/20451 South Laurel Avenue, Tracy and the Assessors Parcel Nos. are 213-050-04/05/06. The site is bordered to the south by a concrete- lined drainage ditch, to the west by Black lake (partially) and to the north by Tom Paine Slough and to the east by Laurel Avenue. It is currently zoned AG-40. The property, and the entire region, has been dry land and irrigated farmed for the last several decades and is currently in alfalfa. Irrigation is provided from the Tom Paine Slough, to the north. There is a single family residence and one outbuilding in the southeast corner of the property. A shed to store farm equipment was in the location of an existing 60' X 160' hay (pole) barn, directly northwest of this house. An on-site domestic well and septic system serves this house. Storm drainage flows to the existing drainage ditch along the south property line. The property is subject to the 100-year flood and did flood last year. 2 Va(Iey Ag Ppearch
