Page 2 Health and Safety Plan and Soil Management Plan Gleason Park Apartments Property April 21,2010 SITE LOCATION AND DESCRIPTION The approximate three-acre subject property is located in an older, predominately residential area of Stockton, San Joaquin County, California (see Plate 1, Vicinity Map). The subject site is presently vacant and unused. The property is bounded to the east by S. Stanislaus Street, to the west by S. American Street, and to the south by E. Church Street. A vacant lot borders the site to the north. An abandoned section of E. Sonora Street traverses the northerly portion of the property. The layout of the property is shown on Plate 2, Plot Plan. Construction of a multi-family development (Gleason Park Apartments) on the property is planned. The development includes a number of apartment buildings, a community center building, pavements, and limited landscaping. Following redevelopment construction, the majority of the site will be capped with buildings and pavements. BACKGROUND The subject property supported up to 20 single-family residences in the past. Many of the residential structures apparently were constructed in the late 1800s. All structures were removed from the property in the mid-2OOOs. Fill materials were imported to the site following demolition activities to fill basement areas and to roughly level the site. The property has since been generally vacant and unused. Environmental investigations at the subject property revealed elevated concentrations of lead sporadically in site soils. The primary source of the lead in site soils is believed to be weathering of lead-based paints from the former residential structures. Site investigation work included the performance of test pits and the collection of a large number of soil samples for laboratory analysis. Lead was identified as the only chemical of concern. In conjunction with the site investigation work, soils excavated from "hot spot" test pit locations were removed from the site for appropriate landfill disposal. Based on the sampling data, the soil removal is indicated to have significantly improved site conditions. A Voluntary Clean-up Agreement (VCA) for the site was established between the State of California Environmental Protection Agency (EPA), Department of Toxic Substances Control (DTSC), and the City of Stockton Housing Department (CSHD). The VCA required the perfonnance of a Preliminary Endangerment Assessment (PEA) to evaluate the soil lead conditions at the site. The PEA work included Human Health Risk Assessment (HHRA) to evaluate the health risks to future potential site receptors posed by the lead in site soils. The results of the HHRA did not demonstrate a high degree of health risk considering the anticipated future use of the site, nor did the HHRA .indicate that potential future exposures to receptors would exceed regulatory metrics. PEA documentation was prepared in late 2009 and early 2010 and submitted to the DTSC.
