Belvedere is a city in Marin County, California, United States, located 1.5 miles (2.4 km) northeast of Sausalito. Situated on two islands, it is immediately adjacent to the Tiburon Peninsula, accessible via a short bridge from the city of Tiburon. At the 2010 census, the population was 2,068 and the per-capita income in 2000 was $250,000, making it one of the highest income cities in California and the 8th highest income place in the United States (1st with a population over 1,000). Belvedere was once an island. Belvedere and Tiburon share a post office. Mail sent there can be addressed as “Belvedere Tiburon, CA”.
Belvedere is located at 37°52′22″N 122°27′52″W, about 4 mi (6 km) north of San Francisco.
Situated on the Tiburon Peninsula at the southeastern base of Ring Mountain, between Richardson Bay and the Town of Tiburon, Belvedere consists of two “islands” and the lagoon (Belvedere Lagoon) between them. The larger of the two islands is Belvedere Island, and the smaller one is Corinthian Island, which is shared with Tiburon. The area of Ring Mountain is notable for its archaeological resources of extant Native American petroglyphs as well as considerable biodiversity of California native plants.
Belvedere Lagoon is owned and maintained by the Belvedere Lagoon Property Owners’ Association. The lagoon is not accessible by boat from San Francisco Bay, and no public access is provided. Until somewhat late in the 20th century, houseboats were present in Belvedere Lagoon.
The city has a total area of 2.42 sq mi (6.3 km2), of which 0.54 sq mi (1.4 km2) is land and 1.89 sq mi (4.9 km2) (78%) is water.
The first settlers arrived in the late 19th century, then the railroad came and Tiburon was the last stop for passengers and cargo destined for San Francisco and beyond. Belvedere Lagoon was partially filled after World War II to provide building sites for tract houses and to improve access to Belvedere Island. It was also once the site of a 9-hole golf course.
Belvedere incorporated in 1896. The first post office opened in 1897.
The City Hall was formerly a Presbyterian Church. It was moved to its present location on San Rafael Avenue in 1949.
Actress Vivian Vance, who played Ethel on I Love Lucy, died in Belvedere in 1979 at the age of 70.
Built on a tradition of volunteerism and caring for the community, the Belvedere Community Foundation was founded in 1990 by a group of residents who avidly appreciated their good fortune in living in magnificent Belvedere. Giving back to the community and providing a catalyst to move it forward are goals of the Foundation’s grant program. As its endowment grows, the Foundation aspires to offer substantial assistance to projects which protect and enhance the quality of life in Belvedere.
