Bolinas Military Reservation

Despite being permanent fixtures, the bunkers lacked heating, water and sewer connections, and latrines. The bunkers were all set into the ground and camouflaged. The first 2 bunkers had 1-inch thick steel domes for protection and manholes for entry, while the third bunker had a reinforced concrete roof and a steel door for access. Additionally, a single M2 .50 caliber antiaircraft machine gun was located just outside the fence line on a small hill behind one of the bunkers.^[2] The bunkers were used to supply target azimuth angles to nearby harbor defense guns.^[3]

In 1948, the harbor defenses of San Francisco, including the Bolinas Military Reservation, were deactivated, and all guns were declared surplus.^[4] In October 1951, the reservation was transferred to the United States Department of the Navy. However, just over a year later, control of the site returned to the United States Army. The General Services Administration gained control of the site in May 1959, before quitclaiming it to a private owner in June 1960.^[2] So far, the United States Government has spent at least $22,000 on cleanup of hazardous materials at the site. The last cleanup effort was in June 2012, with the Department of Defense declaring the cleanup of the site complete.^[5]
