Attachment 4 Site Map.pdf

This is Attachment A, a site map and facilities documentation for a federal contract location, likely related to Federal Fire and Emergency Building (FFEB) systems maintenance or upgrades.

The facility comprises two eight-story administrative buildings totaling 122,300 square feet located at Mare Island in Vallejo, California, near the Napa River. The site includes multiple ancillary structures: Mare Island Naval Shipyard, Vallejo Ferry Terminal, The Sardine Can, Hillcrest Park Homeowners Association, and a Heritage Preserve area. The primary FFEB systems infrastructure consists of a fire pump house, backflow preventers, alarm panels with alarm valves, and emergency generators distributed across the facility. A separate annex storage facility features an internal sprinkler system. Additional facility components identified include parking areas, hotels, transit options, pharmacies, and ATMs in the surrounding vicinity. The documentation indicates key system locations through aerial imagery and overhead facility maps with yellow circular markers denoting critical FFEB equipment placements, backflow prevention devices connected to the water source, and emergency power systems supporting the fire suppression infrastructure.
