1.0 INTRODUCTION AND PROPOSED DEVELOPMENT F urpose of this report was to investigate the property for real or potential environmental mination and report the findings to the Client and the San Joaquin County Environmental h Department (EHD). This report complies with the San Joaquin County Ordinance, 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 for subdivision projects. Within the text of this Report, bolded Section (§)numbers are referenced at the beginning of an applicable sentence,paragraph or Appendices that correspond with the EHD Requirements Checklist for Surface and Subsurface Contamination Reports. 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." The subject property is located approximately milesl east of the FiveComersIntersection at Jack Tone Road. The agriculture management and investment fern of Agriculture Industries, Inc. is representing the owners of the property,Haertl Family Limited Partnership. ��entative Map submittal is being prepared by the engineering firm of Schack&Company. The Map has not been completed as of the date of this report. ✓✓ § 1.1, § 1.2 The current zoning of the Parcel fs�AG-40, and there is no proposal to change the zoning through a General Plan Amendment/Re�Haertl Family Limited Partnership is proposing to subdivide the existing subject Parcel containing 160± acres (152.3± farmable acres) into four Parcels of approximately 40±acres each. At this point in time, there is no proposal to build single family residential structures on any of the future Parcels. There is obvious sufficient land area for a second unit dwelling if so desired, which would have to be in compliance with the San Joaquin County Planning Department. 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 high nitrate concentrations in the underlying groundwater. Point sources investigated on the subject property include: An on-site irrigation well,two on-site domestic wells, a backflow prevention device on the Ag well, and a fertilizer injection system correlated with a sand filtration system. Agrichemical storage/mixing areas are also discussed. Page -2- Chesney Consulting
