Coast Guard Island, Military island base in Oakland Estuary, California.
Coast Guard Island is a 67-acre military installation in the Oakland Estuary that sits between Oakland and Alameda. The island connects to the mainland via a bridge from Dennison Street and houses facilities supporting over 1,200 Coast Guard personnel and their families.
The island was created in 1913 as a result of dredging work that extended the Oakland Estuary toward San Leandro Bay, with Coast Guard operations beginning there in 1926. From 1942 to 1982, it served as a major recruit training center that prepared personnel for service.
The base maintains three national security cutters, the USCGC Stratton, USCGC Bertholf, and USCGC Waesche, representing modern maritime defense capabilities.
Access to the island is highly restricted since it is an active military base where public visits are not generally permitted. The best way to see the installation is from the water through an estuary boat tour or from public viewpoints along the shoreline.
During World War II, the island housed a major recruit training center that prepared thousands of new Coast Guard personnel for service before the program relocated. Though that facility no longer operates, the base remains a significant operational hub for modern Coast Guard activities in the region.
