1.0 INTRODUCTION AND PROPOSED DEVELOPMENT k The purpose of this report was to investigate the subject property, consisting of the Parcel listed on ` the Title Page, 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 Ordinances, specifically 9-905.12(a) for a Surface and Subsurface Contamination Report.-,.According to the San Joaquin County-Development Title, a Surface and Subsurface Contamination Report (SSCR) must be conducted prior to Tentative Map submittal. The subject property is located approximately 1.2 miles west of Interstate 5 on Bowman Road. Mr. Zack Wong, P.E. of Stockton is preparing the Tentative Map for this project, which can be found in Appendix.A. The land area assessed for this Surface.and Subsurface Contamination Report is outlined in red'on this Tentative Map and on the USDA°Soil Survey Aerial Map. Interpretation of County Ordinance Section 9-905.12 (a) has been to focus on the subject property exclusively, unless it is documented or observed that an environmental concern in proximity to the subject property could potentially affect said property. This Surface and Subsurface Contamination approaches,but does not completely encompass the requirements of a Phase I Environmental Site Assessment(ESA) as promulgated by the American Society of Testing and Materials (ASTM E-1527-00). The Environmental Health Department recognizes that the Surface and Subsurface Contamination Report is not intended to completely fulfill the requirements of the Phase I ESA. The Department does however, maintain that certain components of the Phase I ESA must be applicable to the SSCR, as follows: Section 7..1.7 of the ASTM Document states under"Sources of Standard Source Information,"that "information or lother record information from government agencies maybe obtained directly from appropriate government agencies or from commercial services." This report addresses and evaluates non-point sources of hazardous materials, as well as potential point sources. Non-point sources of hazardous materials include potential agricultural chemical residues and the potential for high nitrate concentrations in the underlying groundwater. Point sources investigated on the subject property were aboveground diesel storage tanks, and equipment storage areas. No chemical analysis was conducted for this investigation, nor was there an inspection of any on-site or surrounding buildings or asbestos containing materials (ACMs). -§ 1.1, § 1.2 As referenced, the boundary limits for this SSCR are the red lines as depicted on the Tentative Parcel and District Viewer Maps. The area encompassing the subject Parcel 193-260-27 is 17.62 acres. Current zoning is AG 40, and there is no proposal to change the zoning. Proposed development includes the minor subdivision of the Parcel to create four Parcels and a Designated Remainder. Municipal water and sewer utility hookups are not available at this time, consequently, the property ' -has one irrigation and one domestic well, and four on-site septic systems. R may be a number of years before services arrive in this locale. Since the property is in the Lathrop Sphere of Influence, it is conceivable that services will arrive at some point in the future. - V Page -2- Chesney Consulting
