F RECONNAISSANCE te specific information was obtained from direct observations on February 24,2005, d June 10, 2005. June 10,2005 was the date of the final inspection of the property. 3• There are no domestic or irrigation wells on the property. However, noted near the southwest comer of the property there appears to be the concrete foundation of a prior building or mobile home structure, as illustrated in Photographic Plate B. Historical aerial photographs were obtained from the San Joaquin County Building Department for the years 1983, 1975, 1963, 1952 and 1937. Only the I) 1983 aerial photo shows a structure in this location. Consequently, Building Department records were researched for a permitted structure in this location. Department records indicate that on July 23, 1982, Robert M. Green received a permit for a mobile home foundation,Permit Number BPMF 130889. It is unknown when this mobile home was removed. In addition to this mobile home foundation, a buried concrete structure (See Photographic Plate C) was noted immediately to the south of this apparent mobile home foundation. It appears to be a septic 2Ig'3� tank,but this cannot be confirmed without an investigation with a backhoe or excavator. The entire acreage was walked and surveyed for evidence which may suggest surface and/or subsurface contamination: No hazardous materials were noted on the property. No evidence of drug manufacturing or the dumping of drug-related chemicals was observed on, or near the Frontage Road, or in the middle and rear of the property. There were no tire tracks leading to the back of the property which would indicate dumping. Containers were not observed. No evidence of solid waste disposal was noted, except for two pieces ,�� of cardboard and other non-hazardous solids wastes such as twine,plastic, wood,metal, concrete, and baling wire near the southeast corner of the property. The site was carefully inspected for environmental concerns originating from discolored, 3) disturbed/subsided soils, stressed vegetation or unusual/noxious odors. None of these environmental indicators were observed. As evidenced by the attached photographs, no hazardous materials are stored on-site and there was no indication or observations of spills or other items associated with y} hazardous materials. An important concern associated with the environmental assessment of open properties is the issue of buried pesticide containers or discarded items. It was an occasional practice to dispose of containers or discarded items by this method many years ago. To detect these types of underground artifacts is difficult even with the use of ground penetrating radar or other types of non-intrusive, 3 subsurface analyses. The land surface did not exhibit visual indicators for buried containers such as surfacing of product residue, soil mounding, or localized soil depressions. Given the extreme compactness of the underlying soils, in particular the hardpan stratum that exists in this locale, buried material maybe considered highly unlikely. It is usually after a contaminant plume has impacted a domestic well that buried pesticide containers are iscovered. 4 Chesney Consulting
