Naval Station Treasure Island Naval Station Treasure Island was a United States Navy installation on Treasure Island in San Francisco Bay near San Francisco, California. Constructed for the Golden Gate International Exposition and commissioned for naval use before World War II, the facility served as a training, personnel processing, and maritime logistics hub through the late 20th century. The base intersected with wartime mobilization for the Pacific Theater, Cold War operations associated with the United States Pacific Fleet and downstream urban redevelopment debates involving San Francisco and Alameda County.

History

Treasure Island originated as the site for the Golden Gate International Exposition on Treasure Island and adjacent Yerba Buena Island with construction tied to the Works Progress Administration and planning influenced by the San Francisco Planning Commission and architects active during the Great Depression. The United States Navy acquired the property as tensions rose in the late 1930s, converting exposition halls into barracks and staging areas used during World War II for embarkation to the Pacific Theater, support for Guadalcanal Campaign operations, and demobilization after the Surrender of Japan. In the Korean War and Vietnam War eras the station hosted training and personnel transit supporting the United States Pacific Fleet and allied operations, while Cold War activities reflected broader strategy set by the Department of Defense and directives from the United States Congress. Base closure followed recommendations from the Base Realignment and Closure Commission and negotiations with local authorities culminating in turnover in the 1990s, a process linked to precedents from other installations such as Naval Station San Diego and Pearl Harbor Naval Shipyard.

Facilities and Infrastructure

The station encompassed docks, piers, hangars, barracks, administration buildings, and training ranges constructed atop landfill connecting Yerba Buena Island and the artificial Treasure Island, with civil works informed by engineers from the United States Army Corps of Engineers and contractors experienced with projects for the Works Progress Administration. Notable structures included the former exposition pavilions repurposed as mess halls and headquarters, airfield facilities that interfaced with Naval Air Station Alameda air operations, and piers that supported vessels from the United States Pacific Fleet including auxiliaries and transport ships. Utilities, sewage, and fuel storage on the site later implicated federal agencies such as the Environmental Protection Agency and the Department of the Interior in remediation responsibilities. Infrastructure adaptations during wartime paralleled expansions at other major hubs like Pearl Harbor and Naval Air Station San Diego.

Military Role and Operations

During World War II Treasure Island served as a major embarkation point and processing center for sailors and marines deploying to the Pacific Theater, linking with transit routes to Pearl Harbor, Guadalcanal, and Iwo Jima. The station supported antisubmarine warfare training, logistics staging, and personnel administration for units associated with the United States Pacific Fleet and merchant marine convoys organized under the United States Merchant Marine and War Shipping Administration. In the Cold War period the base hosted training that intersected with strategic planning by the Office of Naval Intelligence and coordination with Naval District commands, while contingency operations connected to crises such as the Korean War and Vietnam War required rapid embarkation and reception capabilities. Cooperative activities with federal agencies and allied forces mirrored interservice coordination models seen in joint bases like Joint Base Pearl Harbor–Hickam.

Environmental Issues and Remediation

Post-closure investigations revealed contamination from petroleum, heavy metals, polychlorinated biphenyls, and asbestos arising from decades of naval operations, fuel storage linked to Navy logistics and ship maintenance similar to contamination at Naval Station Norfolk and Puget Sound Naval Shipyard. Remediation involved the Environmental Protection Agency, the California Environmental Protection Agency, and the Department of Defense under regulatory frameworks influenced by the Comprehensive Environmental Response, Compensation, and Liability Act and state hazardous waste law. Cleanup programs addressed soil and groundwater remediation, removal of underground storage tanks, and asbestos abatement in former barracks and hangars, with community oversight by San Francisco Board of Supervisors and coordination with regional entities like the San Francisco Bay Conservation and Development Commission. Long-term monitoring and landfill stabilization were part of redevelopment conditions negotiated with City and County of San Francisco.

Post-military Use and Redevelopment

After turnover, the site entered phased redevelopment involving proposals for mixed-use neighborhoods, parkland, and maritime access coordinated by the Treasure Island Development Authority and the City and County of San Francisco. Plans referenced urban projects such as Mission Bay, San Francisco and cooperative arrangements with private developers and public agencies including California State Lands Commission and San Francisco Housing Authority. Redevelopment efforts grappled with infrastructure upgrades, seismic retrofits, and compliance with environmental covenants stemming from federal remediation. Proposals have included transit connections to Bay Area Rapid Transit and ferry services linking to San Francisco Ferry Building, while staged housing, commercial, and open-space projects drew input from civic organizations like the San Francisco Planning Commission and neighborhood groups.

Cultural and Historic Preservation

The island's exposition-era architecture and wartime-era buildings attracted attention from preservationists, historians, and cultural institutions including the National Park Service and California Historical Society. Efforts sought to document connections to the Golden Gate International Exposition, maritime mobilization for World War II, and stories of service members processed through the station, aligning with heritage programs similar to collections at the National WWII Museum and oral-history initiatives of the Veterans History Project. Interpretive planning has incorporated partnerships with local museums, the San Francisco Maritime National Historical Park, and academic researchers from institutions such as University of California, Berkeley and San Francisco State University to preserve built fabric, archival materials, and community memory.
