Lit._ _..Environmental Site Assessment Report 20 E.Lindsay Street,Stockton,CA June 24,2004 Page 2 2.3 AERIAL PHOTOGRAPHS AND TOPOGRAPHIC MAPS Aerial photographs from 1957, 1970, 1982, and 1993 were reviewed. All of the aerial photographs indicate that a structure has been at the site since at least 1957 with a possible yard in the rear of the property. The adjacent properties have generally been occupied by structures through the years according to the photographs. A parking lot appeared at the northeastern corner of E. Miner Avenue and N. Center Street in the 1970 photograph. No other changes to the site vicinity appear to have occurred according to the photographs.The aerial photographs are included in Appendix B. United States Geological Survey Topographic Maps from 1952, 1968, 1976, and 1987 were reviewed. The maps indicated that the site was located in a developed area, but no detail was provided. The topographic maps are included in Appendix B. 2.4 ENVIRONMENTAL DATABASE SEARCH AND SJCEHD FILE REVIEWS Locations identified in the guidelines set forth in Practice E 1527-00, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process published in May 1993 (Revised 2000) by the American Society for Testing and Materials (ASTM) specified databases within the specified search radii are included the EDO Radius Map with GeoCheck® report in Appendix B. The search of the databases revealed information pertaining to numerous locations, as is commonly the case for downtown Stockton properties. Due to the large number of identified locations, only those properties located within close proximity of the site were further investigated at the SJCEHD. The following database address and the site property address were submitted to SJCEHD and the non-confidential portions of their files were researched: • 6 Lindsay Street • 20 Lindsay Street(the site) • 303 El Dorado Street • 345 El Dorado Street • 425 El Dorado Street SJCEHD had records for one of the locations submitted. The results of the review of documentation on file at SJCEHD are summarized below: • 425 N. El Dorado Street is the location of the Stockton City Hall. A Radioactive Materials License was on file for this location regarding the use of gauges for moisture density readings. The databases specified by ASTM are commonly subject to infrequent and partial updating. This is especially true of those locations that no longer warrant inclusion in a given database. It is therefore not unusual to fail to find supporting documentation for locations identified in the ASTM specified database search on file with local regulatory agencies. 2.5 SITE RECONNAISSANCE A walking site reconnaissance was conducted on May 20, 2004. The interior and exterior areas of the site were viewed. The site manager, Mr. Al Lee, indicated that he had leased the property for approximately the last 20 years, and that he had no knowledge of any USTs on site. An oil-water separator was noted in the floor of the garage. The soil areain the rear of the property was covered with several inches of gravel. Other than some incidental motor oil staining from parked vehicles,no indications of contaminated soil or is CONDOR
