Bolsa Chica Military Reservation
Bolsa Chica was established early in 1942 on the property of the Bolsa Chica Gun Club. The lower lagoon level was chosen to house the first temporary mobile battery and the gun club's clubhouse became a temporary barracks. Construction began for the temporary battery and for two modern larger caliber gun batteries even before all the property was formally acquired. The two new modern batteries were located on a higher mesa overlooking the lagoon in the middle of the reservation.
The reservation was initially armed with two tractor-drawn 155mm GPF Guns in field emplacements right after the U.S. entry into World War II. The initial field emplacements were replaced with two reinforced concrete Panama mounts for the 155mm guns that were completed in February 1942, see Battery 155 - Bolsa Chica. While this battery was completed in February 1942, it was not formally accepted for service until 15 Nov 1943.
The reservation was deactivated after the end of the war in 1948.
Additional structures on the reservation included an underground Plotting-Switchboard-Radio (PSR) structure for Battery 128, a reserve ammunition magazine, a fire control tower and a SCR-296A Radar installation.
