INTRODUCTION Mr. Henry Van Vuren is creating a second parcel from property he owns at 7663 Stow Avenue east of Stockton, California. The purpose of this project is to create a homesite parcel which is removed from the remaining property. 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." 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, and the nitrate concentration in the underlying groundwater. Point sources investigated include off-site and on-site fuel storage tanks, empty drums and five gallon containers, septic systems and equipment storage areas. No chemical analysis was conducted for this investigation, nor was there an inspection of the existing structures for asbestos containing materials (ACMs). An analysis of the domestic well serving the Van Vuren's current house was not tested for nitrates and the agrichemical dibromochlorpropane (DBCP). If the project continues as planned, this well will be tested for completion of the Soil Suitability Study. SITE DESCRIPTION 1 As illustrated on the attached Assessor's Parcel Map, Parcel 1 will be the homesite Parcel consisting of 3.1± acres and Parcel 2 will be 53.9± acres. The homesite parcel currently has the Van Vuren residence with a septic system, a detached garage and shed, cattle mangers, and dairy farm equipment storage. In the northeast portion of Parcel 1, there is a farm worker's mobile home with a septic system, a shop, a shed and storage of farming related items and parts. Parcel 2 is currently planted in entirely in pasture grasses,which are not rotated with other crops. These �Z r pasture grasses provide forage for the former Van Vuren Dairy, which was recently sold to another dairyman. The site is bordered to the north, south, east and west by agricultural production land, including 3) vineyards, pasture, a recently planted almond orchard, and low density single family housing. Gawne Road is the south property border. Little Johns Creek runs through the property. Parcel 2 extends to the north of this Creek. The former Van Vuren Dairy is currently an organic dairy and has been organic for the past six years. The dairy is located west-southwest of the subject property. No antibiotics, etc. are used on the dairy animals and no agrichemicals are applied to the cropland that is, or was under the control of the dairy. 1 Chesney Consulting
