Base Property and Historical Use
Naval Station (NS) Treasure Island is in San Francisco Bay, midway between San Francisco and Oakland, California. The facility consists of two contiguous islands: the northern island is named Treasure Island (TI) and the southern island is named Yerba Buena Island (YBI). TI is a man-made island and was constructed of sediments dredged from San Francisco Bay. YBI is a natural island. TI was constructed in 1936 and 1937 for the initial purpose of hosting the Golden Gate International Exposition Worlds Fair held in 1939-1940. The Navy acquired it by condemnation in 1942. Military activities at NS Treasure Island date back to 1866 when the U.S. Government took possession of YBI for defensive fortifications. The Navy operated the first West Coast Naval Training Station on YBI until 1923, when the center was transferred to San Diego. YBI continued to function as a Naval Receiving Station until World War II, when naval operations were transferred to TI. In response to the Navy's request in 1941, the City of San Francisco leased TI to the Navy for the duration of World War II. The island became a major naval facility, processing approximately 12,000 military personnel per day for service overseas and upon their return to the United States.
Closure date, planned reuses, parcels transferred
NS Treasure Island was closed on 30 September 1997, as a BRAC III Major Closure. The DoD Office of Economic Adjustment (OEA) designated San Francisco as the Local Redevelopment Authority (LRA) for NS Treasure Island in May 1994. In 1997 the California State Legislature created a special reuse authority for Treasure Island, transferring the LRA status from San Francisco to the Treasure Island Development Authority (TIDA). TIDA is a state agency staffed by the San Francisco mayor’s office and is the entity responsible for planning the reuse and redevelopment of the former installation.
The U.S. Department of Labor received approximately 36 acres of property and associated facilities on Treasure Island for its Job Corps program. The U.S. Coast Guard received approximately 11 acres of property on YBI and approximately 12 acres of associated submerged lands. The Federal Highways Administration acquired approximately 24 acres of property on YBI for the construction and operation of the new bay bridge.
On May 29, 2015 TIDA received approximately 707 acres of upland and submerged lands of Treasure Island and approximately 87 acres of uplands and submerged lands of YBI in support of its redevelopment plans. All remaining property will be transferred to TIDA in phases as environmental cleanup actions are completed by the Navy.
