The 1937 aerial photograph depicts north-south linear striations in soil which could be associated with soil cultivation within the Site footprint, however, there are no indications of crops or on-site structures. A north-south irrigation canal appears to be within the western one-third of the Site footprint. The 1957 aerial photograph provides no indications of crops; features appearing to be sheds or outbuildings with disturbed soil are within the southeastern portion of the Site footprint. The canal is not present. The 1963 aerial photograph provides no indications of crops. Two residential structures with associated landscaping are within the east-central and southeastern portions of the Site footprint. A barn-like structure with smaller sheds or outbuildings are within the east-central portion of the Site footprint. The ground surface in the east-central portion of the Site footprint between the northern-most residential structure and the barn appears to be overlaid with hardscape or hard- packed/gravel-paved surface. The 1968 aerial photograph indicates conditions, including an absence of crops, are similar to conditions in the 1963 aerial photograph. The 1975 aerial photograph indicates conditions, including an absence of crops, are similar to conditions in the 1963 and 1968 aerial photographs. The 1982 aerial photograph indicates conditions, including the absence of crops, are similar to conditions in the 1963 through 1975 aerial photographs. Filters applied to the 1982 photograph show landscaping and other indications of plant growth within the Site footprint with a red hue. Features that appear to be agricultural produce hauling trailers are parked en echelon to the northwest and southwest of the barn. The ground surface in most of the central and eastern portions of the Site footprint appears to be covered with gravel or other form of a surface material amenable to driving and parking heavy equipment. In sum, there is no obvious evidence from review of the available aerial photographs that indicate the Site was actively cultivated with crops while the western half of the Site historically has been unpaved and not occupied by structures or equipment. However, off-site areas particularly to the south and northeast of the Site appear to have been actively cultivated until sometime prior to 1982. The Site was occupied by what appeared to have been rural and possible farm-related residential structures with an associated barn, sheds and outbuildings and storage of portable agricultural equipment. Therefore, while it appears unlikely that environmentally persistent agricultural pesticides were presumably applied uniformly, for agricultural purposes consistent with normal Sampling and Analysis Workplan Tracy Corners Shopping Center 3225 North Tracy Boulevard Tracy,California 95376 Partner Project Number SM14-129814 Docket Number HAS-VCA 14/15-108 August 15,2016 Page 10
