EXPLANATION: a -d) A Phase I Environmental Site Assessment has been prepared for the proposed project to identify the potential for onsite or nearby soil or groundwater contamination (Stantec, 2008). Based on a preliminary review of available aerial photographs and topographic maps, Site 1 has been a BART parking lot since at least 1982 and there are no permanent building structures located on the property. Prior to that, commercial buildings and residential dwellings were present on the property, as viewed from available aerial photographs and topographic maps. Site 1 is surrounded by San Leandro Boulevard and the San Leandro BART Station to the west, Carpentier Street and residential land uses to the east, West Juana Avenue and residential and commercial buildings to the south and West Joaquin Avenue and Saint Leander's Church and School to the north. No pits, ponds, lagoons or waterways were observed on the adjacent properties. Site 2 has been vacant since the Del Monte facility was demolished in 1989. Observations of the adjoining properties provided indications of past usage and activities. A Phase II Environmental. Site Assessment was also prepared (Iris Environmental, January, 2009). The Phase I1 ESA results assessed the environmental quality of soil gas, soil and groundwater beneath Site 1. Sampling of soil gas, soil and groundwater at Site 1 was completed in a grid -like fashion across the site to identify potential environmental restrictions that may be encountered in the future and were analyzed for volatile organic compounds (VOCs). Tetrachloroethylene (PCE), benzene and 1, 3-butadine were the only VOCs in soil gas detected at concentrations greater than their most conservative California Human Health Screening Levels (CHHSLs)_ Two soil samples were collected from each sample location at various depths utilizing USEPA methods. Polynuclear Aromatic Hydrocarbons (PAHs) were detected in two samples from two distinct sample locations. Various metals were detected in all of the tested soil samples, although they were not elevated above what is expected in local, native soils. The only metal detected at concentrations above agency screening levels was arsenic. Asbestos was not detected in any soil samples. Cornerstone at San Leandro Crossings Initial Study 15 March 2009
