INTRODUCTION Mr. Gerald Straw is proposing to create three lots from a 0.638 acre parcel of land located in southeast Stockton. Mr. Zack Wong, P.E. of Wong Engineers is the civil engineer for the project. The attached tentative map illustrates the dimensions and orientation of the three proposed parcels. According to the San Joaquin County Development Title, a Surface and Subsurface Contamination Report (SSCR) must be conducted prior to 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. Our 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 and other contaminants. Point sources investigated that may have affected the subject property include industrial sites and production facilities, fuel storage tanks, septic systems, potential drug manufacturing chemicals, storage and mixing areas of chemicals and containers such as drums. No chemical analysis was conducted for this investigation, nor was there an inspection of any nearby older buildings and older residential structures near the project for asbestos containing materialsCMs). The subdivision will be connected to the City_kf Stockton water(Cal Water Service) a-d sewer for domestic water and sewage isposa—cervices. onse-C-quenTy, it is our understanding that Nitrate Loading and Soil Suitability Studies will not be required by the San Joaquin County Environmental Health Department. There is no on-site well to test for nitrates and the agrichemical dibromochloropropane (DBCP). SITE AND SURROUNDING PROPERTY DESCRIPTION Mr. Straw currently owns the property and is proposed to be developed into single family residential units.
