r - INTRODUCTION Mr. Manuel Costa is creating a second parcel from property he owns at 6425 Linne Road in Tracy, CA. 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, 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. 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 residential structure for asbestos containing materials (ACMs). An analysis of the domestic well serving the house on proposed Parcel "A" will be tested for nitrates and the agrichemical dibromochlorpropane (DBCP) for the Soil Suitability Study. The Soil Suitability Study is also required for this project by the San Joaquin County Environmental Health Department. SITE DESCRIPTION As illustrated on the attached Tentative Map, the Designated Remainder(REMAINDER PARCEL) consists of a rectangular shaped, flat 48.71 acre parcel that is planted currently in beans which is rotated with tomatoes. Parcel "A" is slightly elevated from the Remainder and is 3.00 acres. It contains the Costa's single family residence which was built in 1990. An on-site r-� domestic well and septic system serves this house. There has never been any problems with the septic system. Storm drainage is existing natural drainage, primarily toward the Remainder Parcel. The property is not subject to the 100-year flood. The site is bordered to the north, south, east and west by agricultural production land and rural, very low density single family housing (ranchettes). Adjacent to the east is a new single family residence that is currently under construction. The subject property is currently zoned Agriculture-40 and will remain so. There are no easements traversing proposed Parcel "A." The property has been farmed in row crops for several decades. The surrounding area and region has been dry land and irrigated farmed,particularly in orchards, row crops and pasture also for the last several decades. Irrigation is provided from irrigation wells and the Banta Carbona Irrigation District. Page -1- Valfey Ag Research
