It contains 100 contributing resources built from 1938 onward under U.S. Navy Bureau of Yards and Docks plans.","why_significant":"The district is significant at the statewide level for its ties to the strategic development of naval air stations in the 1930s, California naval facilities during World War II, and Navy operations in the Pacific theater. It also embodies the Navy's 'total base design,' a Beaux Arts layout with Moderne buildings and a designed landscape.","narrative":"Naval Air Station Alameda occupies the western half of Alameda Island in San Francisco Bay, and its historic district covers about 406.5 acres of the former base. Construction began in 1938 under the Navy's Bureau of Yards and Docks, which planned the station as a single 'total base design' with a formal, symmetrical Beaux Arts layout. Four functional areas organize the district: the Administrative Core, Shops Area, Residential Area and Operations Area. Most prominent buildings, including the landplane and seaplane hangars, the Control Tower and the Administration Building, use the Moderne style. The district counts 100 contributing resources: 99 buildings and structures plus a designed landscape of evenly spaced plantings and sightlines. It was recognized for its role in the strategic growth of naval air stations in the 1930s, California's World War II naval build-up and Pacific operations, and for its architecture, landscape architecture and community planning. The period of significance runs from 1938 to 1945.","period_of_significance":"1938-1945","architect_builder":"U.S. NAVY; BUREAU OF YARDS & DOCKS","architectural_style":"MODERN MOVEMENT / Moderne","criteria":["A","C"],"status_note":"Current functions listed include work in progress, housing, commerce, municipal use, a museum and industrial storage; interiors have been heavily modified through reuse.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.80536-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/12001191.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/12001191/53b3b16687-800.webp","url_1600":"https://nationalhistoricalregister.com/media/12001191/53b3b16687-1600.webp","licence":"Public domain","author":"USN","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NAS_Alameda_NAN2_47.jpg\" rel=\"noopener\">USN</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:NAS_Alameda_NAN2_47.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858288","wikipedia":"https://en.wikipedia.org/wiki/Naval_Air_Station_Alameda","wikidata":"https://www.wikidata.org/wiki/Q3016749"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/naval-air-station-alameda-historic-district-12001191/"}
