Project Description
Fill Site 6B (FS6B) is located on the Presidio’s Main Post. It is irregularly shaped and extends from Lincoln Boulevard and Tomey Avenue to the south, Doyle Drive to the north, General Kennedy Avenue to the east, and Halleck Street to the west. The site includes Buildings 1027, 1028, 1029, 1030, and 1158 that are used for commercial and residential purposes. The site also includes paved vehicle parking and driving areas and landscaped open space.
FS6B contains debris from the 1975 demolition of the former Letterman Army Medical Center and other nearby buildings. the debris fill and soil contain metals, polycyclic aromatic hydrocarbons (PAHs), pesticides, and petroleum hydrocarbons at concentrations that are safe under current site conditions.
In November 2013, the California Department of Toxic Substances Control (DTSC) approved an environmental investigation called a Preliminary Endangerment Assessment (PEA) and Land Use Control (LUC) for the site. The PEA is the initial investigation of the site and determines if there has been a release of hazardous substances that present a risk to human health or the environment. The PEA for FS6B assesses the potential human health and ecological risks from building debris in soil. It concludes that building debris in soils at FS6B do not pose a risk to human health or the environment under current land use. To ensure continued protection of human health and the environment, DTSC requires a LUC with a soil management plan for future land use changes.
The PEA for FS6B is available for review at the Presidio Trust Library, 103 Montgomery Street, Presidio and can be downloaded below.
