San Francisco Bay Area
The San Francisco Bay Area, commonly known as the Bay Area, is a region of California surrounding and including San Francisco Bay, and anchored by the cities of Oakland, San Francisco, and San Jose. The Association of Bay Area Governments defines the Bay Area as including the nine counties that border the estuaries of San Francisco Bay, San Pablo Bay, and Suisun Bay: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties which are not officially part of the San Francisco Bay Area, such as the Central Coast counties of Santa Cruz, San Benito, and Monterey, or the Central Valley counties of San Joaquin, Merced, and Stanislaus. The Bay Area is known for its natural beauty, prominent universities, technology companies, and affluence. The Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a complex multimodal transportation network.
The earliest archaeological evidence of human settlements in the Bay Area dates back to 8000–10,000 BC. The oral tradition of the Ohlone and Miwok people suggests they have been living in the Bay Area for several hundreds if not thousands of years. The Spanish empire claimed the area beginning in the early period of Spanish colonization of the Americas. The earliest Spanish exploration of the Bay Area took place in 1769. The Mexican government controlled the area from 1821 until the 1848 Treaty of Guadalupe Hidalgo. Also in 1848, James W. Marshall discovered gold in nearby mountains, resulting in explosive immigration to the area and the precipitous decline of the Native population. The California gold rush brought rapid growth to San Francisco. California was admitted as the 31st state in 1850. A major earthquake and fire leveled much of San Francisco in 1906. During World War II, the Bay Area played a major role in America's war effort in the Asiatic-Pacific Theater, with the San Francisco Port of Embarkation, of which Fort Mason was one of 14 installations and location of the headquarters, acting as a primary embarkation point for American forces. Since then, the Bay Area has experienced numerous political, cultural, and artistic movements, developing unique local genres in music and art and establishing itself as a hotbed of progressive politics. The postwar Bay Area saw large growth in the financial and technology industries, creating an economy with a gross domestic product of over $700 billion. In 2018 it was home to the third-highest concentration of Fortune 500 companies in the United States.
The Bay Area is home to approximately 7.52 million people. The larger federal classification, the combined statistical area of the region which includes thirteen counties, is the second-largest in California—after the Greater Los Angeles area—and the fifth-largest in the United States, with over nine million people. The Bay Area's population is ethnically diverse: roughly three-fifths of the region's residents are Hispanic/Latino, Asian, African/Black, or Pacific Islander, all of whom have a significant presence throughout the region. Most of the remaining two-fifths of the population is non-Hispanic White American. The most populous cities of the Bay Area are Oakland, San Francisco, and San Jose, the latter of which had a population of 969,655 in 2023, making San Jose the area's largest city and the 13th-most populous in the United States. The San Francisco Bay Area's population has the third-oldest median age, following two Florida metros; and it is the fastest-aging of any metropolitan area in the U.S., described as a demographic "doom loop".
Despite its urban character, San Francisco Bay is one of California's most ecologically sensitive habitats, providing important ecosystem services such as filtering the pollutants and sediments from rivers and supporting a number of endangered species. In addition, the Bay Area is known for its stands of coast redwoods, many of which are protected in state and county parks. The region is additionally known for the complexity of its landforms, the result of millions of years of tectonic plate movements. Because the Bay Area is crossed by six major earthquake faults, the region is particularly exposed to hazards presented by large earthquakes. The climate is temperate and conducive to outdoor recreational and athletic activities such as hiking, running, and cycling.
The Bay Area is host to teams in each of the five largest North American men's professional sports leagues and is a cultural center for music, theater, and the arts. It is also host to numerous higher education institutions, including research universities such as the University of California, Berkeley, and Stanford University, the latter known for helping to create the high tech center called Silicon Valley. Home to 101 municipalities and 9 counties, governance in the Bay Area involves numerous local and regional jurisdictions, often with broad and overlapping responsibilities.

Yerba Buena Island
Yerba Buena Island (Spanish: Isla Yerba Buena) sits in San Francisco Bay within the borders of the City and County of San Francisco. The Yerba Buena Tunnel runs through its center and connects the western and eastern spans of the San Francisco–Oakland Bay Bridge, linking the city with Oakland, California. Treasure Island is connected by a causeway to Yerba Buena Island. According to the United States Census Bureau, Yerba Buena Island and Treasure Island together have a land area of 0.901 square miles (2.33 km2) with a total population of 2,500 as of the 2010 census.
Yerba Buena Island has had several other names over the decades: Sea Bird Island, Wood Island, and Goat Island. The island may have been named after the pueblo of Yerba Buena, which was named for the plant of the same name that was abundant in the area. The plant's English and Spanish common name, Yerba buena, is an alternate form of the Spanish hierba buena (literally meaning 'good herb'), generally used to describe local species of the mint family.
Today, the military reservation southeast of the Yerba Buena Tunnel belongs to the United States Coast Guard (USCG) District Eleven. The US Coast Guard Sector San Francisco – Vessel Traffic Service (VTS) tower is located on Signal Road Building 278 atop the peak of the island. The US Coast Guard Sector San Francisco Headquarters is co-located with US Coast Guard Station San Francisco on Healy Avenue and Fresnel Way at water-level on the southeast coast of the island. The Coast Guard Aids to Navigation San Francisco has a navigational buoy repair facility on Fresnel Way. The USCG Senior Officers' residences are in Quarters A, B, C, 8 and 9 off of Hillcrest Road on the hill atop the USCG base. During the summer of 2011, the Department of Homeland Security / United States Coast Guard opened the new SAFE Port Act (2006) Interagency Operations Center (IOC at Building 100 site on Spindrift Circle) on the US Coast Guard Sector / Station San Francisco base. The IOC houses the VTS, WatchKeeper and the US Coast Guard Sector San Francisco Command Center together in one building.

Yerba Buena Tunnel
The Yerba Buena Tunnel, also known as the Yerba Buena Island Tunnel, is a highway tunnel in San Francisco, California. It is the part of San Francisco–Oakland Bay Bridge complex that crosses Yerba Buena Island. The Yerba Buena Tunnel carries ten lanes of Interstate 80 (I-80) on two decks, connecting the two component spans of the Bay Bridge, the western suspension span and the eastern self-anchored suspension span. At the opening of the Bay Bridge in 1936, it was the world's largest-bore tunnel.

Administration Building, Treasure Island
The Administration Building, Treasure Island, on Treasure Island, California, is a Moderne style building designed by William Peyton Day and George William Kelham. It has also been known as Building 1, as Command Naval Base San Francisco Headquarters, and as Naval Station Treasure Island. It was listed on the National Register of Historic Places in 2008.
Construction began in 1937 with landfill and site preparation, and was completed in 1938. During the Golden Gate International Exposition the building functioned as the terminal for Pan American Airways China Clipper transpacific flying boat service. The United States Navy took over Treasure Island when the exposition ended and rather than continue as an airport, the building became an administration building.
The building housed a museum until 1997. In 2011, San Francisco purchased Treasure Island from the U.S. Navy and there are plans to reopen the museum as part of a redevelopment project.
