In 1974 the base was renamed Rio Vista Storage Activity Site and control was transferred to the Presidio of San Francisco. Its mission was changed to Logistics Over The Shore (LOTS) operations training. In 1971 the "USAT Resolute," a cargo and training ship, was moved to the Rio Vista facility. In 1980 the facility was transferred to the U.S. Army Reserve and renamed the Rio Vista United States Army Reserve Center (Rio Vista USAR Center). It was primarily used for training purposes by engineering and transportation units. In 1992 the facility was closed and all equipment was removed. The city of Rio Vista purchased the property from the federal government in 2003. It remains empty, but the city has proposed a redevelopment plan for the property. Two of the proposed uses are a research and monitoring station to study the river and the Delta, and a fish refuge and fish hatchery. Other proposed new uses include hiking and picnic areas, a boat dock, hotels, and a conference center.
