1.0 INTRODUCTION AND PROPOSED DEVELOPMENT 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 three-quarters of a mile southeast of the town of Thornton on Kite Road. Mr. Mike Farley, PLS of Stockton is preparing the Tentative Map for this project, which is in the process of being completed. The land area assessed for this Surface and Subsurface Contamination Report is outlined in red on the Assessor's Parcel 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 other record information from government agencies may be 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 mobile diesel tanks, stationary above ground fuel tanks, a recirculating pressure wash-pad area, and agrichemical mixing 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 Assessor's Parcel Map. The area encompassing the subject Parcel 001-180-12 is 56.96 acres. There is a small Parcel (APN 001-180-13) at the southern apex of the triangular shape of the subject property. This Parcel consists of 4.22 acres as noted on the APN Map, and is farmed contiguously with the subject Parcel. Current zoning is AG 40, and there is no proposal to change the zoning. Proposed development includes the minor subdivision of Parcel "12" to create a three-acre homesite Parcel near the center of this Parcel. Page -2- Chesney Consulting
