Treasure Island Naval Station Hunters Point Annex

The San Francisco Naval Shipyard was a United States Navy shipyard in San Francisco, California, located on 638 acre of waterfront at Hunters Point in the southeast corner of the city. Originally, Hunters Point was a commercial shipyard established in 1870, consisting of two graving docks purchased and upbuilt in the late nineteenth and early twentieth century by the Union Iron Works company, later owned by the Bethlehem Shipbuilding Company and named Hunters Point Drydocks, located at Potrero Point.

History
The original docks were built on solid rock. In 1916 the drydocks were thought to be the largest in the world. At over 1000 feet in length, they were said to be big enough to accommodate the world's largest warships and passenger steamers. Soundings showed an offshore depth of sixty-five feet. During the early 20th century much of the Hunters Point shoreline was extended by landfill extensions into the San Francisco Bay.

Between World War I and the beginning of World War II the Navy contracted from the private owners for the use of the docks. The docks provided deep-water facilities between San Diego and Bremerton, Washington. The main naval base in the area was at Mare Island Naval Shipyard, but the continuous silting in the area made it only suitable for relatively shallow-draft ships. A Congressional hearing on Pacific Coast Naval Bases was held in San Francisco in 1920 at San Francisco City Hall, wherein city representatives, Mayor Rolph, City Engineer O'Shaughnessy and others testified on behalf of permanently siting the Navy at Hunters Point.

At the start of World War II the Navy recognized the need for greatly increased naval shipbuilding and repair facilities in the San Francisco Bay Area, and in 1940 acquired the property from the private owners, naming it Hunters Point Naval Shipyard. The property became one of the major shipyards of the west coast. It was later renamed Treasure Island Naval Station Hunters Point Annex. During the 1940s, many workers moved into the area to work at this shipyard and other wartime related industries.

The key fissile components of the first atomic bomb were loaded onto the USS Indianapolis in July 1945 at Hunters Point for transfer to Tinian. After World War II and until 1969, the Hunters Point shipyard was the site of the Naval Radiological Defense Laboratory, the US military's largest facility for applied nuclear research. The yard was used after the war to decontaminate ships from Operation Crossroads. Because of all the testing, there is widespread radiological contamination of the site. After the war, with an influx of blue collar industry, the area remained a naval base and commercial shipyard. The Navy operated the yard until 1974, when it leased most of it to a commercial ship repair company.

The Hunters Point Shipyard Artists (HPSA) is a community of artists who rent studios in the former U.S. naval shipyard on Hunters Point in the Bayview community of San Francisco. An artist community since 1983, the Hunters Point Shipyard is now home to more than 250 artists.

In 1989, the base was declared a Superfund site requiring long-term clean-up.

The Navy closed the shipyard and Naval base in 1994 as part of the Base Realignment and Closure Commission (BRAC). Besides radioactive contamination, Hunter's Point had a succession of coal- and oil-fired power generation facilities which left a legacy of pollution, both from smokestack effluvium and leftover byproducts that were dumped in the vicinity. The BRAC program has managed the majority of the site´s numerous pollution remediation projects.

New homes built on the property were set to be available to tenants in the winter of 2014/2015. The first residents began moving in in June 2015.
