Project Description
Fill Site 6B (FS6B) is located in 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 drive areas and landscaped open space.
FS6B contains debris from demolition of the former Letterman Army Medical Center and other nearby buildings in 1975. Debris fill and soil contain metals, polycyclic aromatic hydrocarbons (PAHs), pesticides, and petroleum hydrocarbons at concentrations that are safe under current site conditions. Because much of the area is covered with pavement or landscaping, the Trust plans to manage debris fill at FS6B in place.
Schedule
The Presidio Trust completed investigations at FS6B in 2009. A Remedial Investigation Summary Report was submitted to the California Department of Toxic Substances Control in February 2012. Based on results of the remedial investigation and risk assessment, the Trust will prepare a Draft Feasibility Study/Remedial Action Plan (FS/RAP) to propose managing the fill and debris in place. The Draft FS/RAP is scheduled to be issued for public comment in mid- to late-2012.
