The Phase I ESA was performed in accordance with the guidelines set forth in Practice E 1527-00, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process, published in July 2000 by the American Society for Testing and Materials (ASTM), and in accordance with the prevailing standard of care for completing such assessments in California at this time.

Based on the information provided by file reviews, owner/occupant questionnaires, interviews, site reconnaissance, historical research, and aerial photos, the following environmental conditions were revealed: FINDMGS Condor identified three recognized environmental conditions do the site and adjoining properties (Figure A). • The property at 145 N. Grant Street (730 E. Channel Street), the former Stockton Metropolitan Transit District facility may contain USTs. San Joaquin County PIJS/EHD records indicate 10 USTs were present on the property in 1985. Two USTs were removed in 1987, but there are no records indicating the status of the remaining eight USTs. The existence of USTs on site, both past and present, represents a potential risk to soil and groundwater. The 1940 Polk City Directory for Stockton indicates a gas station was located at 802 E. Miner Avenue_ No other records were found pertaining to the gas station at this address. There was no listing for this address in the 1945 city directory. The type and number of fuel tanks installed at the gas station, and their disposition after the removal of the gas station, is not known.If USTs are still on site, then they represent a potential risk to soil and groundwater. • A groundwater investigation is currently in progress at 308 N. Grant Street. This property north of the site across Miner Avenue. Records indicate high concentrations of c ntaminantsated are present in the groundwater at this property. It is possible, though not known, that contaminants in the groundwater beneath this property have migrated to the southeast and are now present in groundwater beneath the site.
