3.0 SUBJECT PROPERTY CHARACTERISTICS 3.1 SITE DESCRIPTION The Property consists of a 15,000 square foot parcel of land improved with a rectangular single-story auto repair building and a rectangular single-story office/storage building. The auto repair building is located on the northwestern portion of the parcel while the storage building is located on the southeastern portion of the parcel. The remainder of the Property is paved and used for parking and driveways. Figure 2 illustrates the site map. Site photographs are included in Appendix A. 3.2 BACKGROUND HISTORY ENCON had conducted a Phase I Environmental Site Assessment on September of 2013. The followings are excerpted from the previous Phase I ESA. The following were observed at the time of site reconnaissance: • One approximate 500-gallon above ground used oil collection tank was observed in a concrete bunker on the south-central portion of the Property. • Three empty 55-gallon drums and three 55-gallon drums containing used oil filters and rags were observed outside auto repair building • One empty 55-gallon drum was observed inside of the auto repair building • Various containers of new oil, grease and auto fluids were observed within the auto repair building. • Oxygen/acetylene tanks were observed within the auto repair building • Various quantities of old auto parts, empty buckets and containers and other discarded materials were observed throughout the site. Based on review of Sanborn Map Company fire insurance maps, in 1917 the Property was improved with a dwelling, two outbuildings and a building labeled as housekeeping rooms. In 1950, the Property was improved with two dwellings, three detached garages and an apartment building. A building permit to demolish an apartment house was issued in 1960 and a permit to construct an auto repair building was issued in 1963. Fire insurance maps show that in 1972 the western portion of the Property was improved with a dwelling, a detached garage and an outbuilding, while the central eastern portion was improved with a building labeled as auto repair including a yard to the north, south and west labeled as wrecked auto storage. Building records indicate that the current storage building on site was constructed in 1985. Based on historical aerial photographs, sometime between 1972 and 1993, the residence on the western portion was demolished, while the building on the central east portion remained through at least 1998. Building records indicate that the current auto repair building was constructed in 2001. Historical city directories list the Property as residential from 1921 through 1955, Clayton's Garage & Tow Service from 1965 through 1979 and Juan's Auto Repair from 1990 through 2012. Based on review of the EDR Radius Map report, the Property appears on the UST/CA FID UST/SWEEPS UST databases in association with a closed 1,000-gallon UST. No further information was available for the UST removal. Due to the risk of a release of hazardous materials from past on site activities, a subsurface investigation was recommended.
