Kellersberger's Map is a plat map created in 1854 of Rancho San Antonio on the northeastern shore lands, the Contra Costa of San Francisco Bay , in present day Alameda County, California . The area surveyed today comprises the entire extent of the cities of Berkeley and Albany , and the northern part of Oakland, including its downtown and waterfront.
100-404: Berkeley ( / ˈ b ɜːr k l i / BURK -lee ) is a city on the eastern shore of San Francisco Bay in northern Alameda County , California , United States. It is named after the 18th-century Anglo-Irish bishop and philosopher George Berkeley . It borders the cities of Oakland and Emeryville to the south and the city of Albany and the unincorporated community of Kensington to
200-468: A shellmound , now mostly leveled and covered up, along the shoreline of San Francisco Bay at the mouth of Strawberry Creek . Human remains and skeletons from Native American burials have been unearthed in West Berkeley and on campus alongside Strawberry Creek . Other artifacts were discovered in the 1950s in the downtown area during remodeling of a commercial building, near the upper course of
300-518: A collaboration with the State of California that culminated in 1868 with the creation of the public University of California . As construction began on the new site, more residences were constructed in the vicinity of the new campus. At the same time, a settlement of residences, saloons, and various industries grew around the wharf area called Ocean View . A horsecar ran from Temescal in Oakland to
400-689: A halt. Facing rising housing costs, residents voted to enact rent control and vacancy control in 1980. Though more far-reaching in their effect than those of some of the other jurisdictions in California that chose to use rent control where they could, these policies were limited by the Costa-Hawkins Rental Housing Act , a statewide ban on rent control that came into effect in 1995 and limited rent control to multi-family units that were built (or technically buildings that were issued their original certificate of occupation) before
500-1022: A hotspot for polybrominated diphenyl ether ( PBDE ) flame retardants used to make upholstered furniture and infant care items less flammable. PBDEs have been largely phased out and replaced with alternative phosphate flame retardants. A 2019 San Francisco Estuary Institute (SFEI) study assayed a wide range of these newer flame retardant chemicals in Bay waters, bivalve California mussels ( Mytilus californianus ), and harbor seals ( Phoca vitulina ) which haul out in Corkscrew Slough on Bair Island in San Mateo County , with phosphate flame retardant contaminants such as tris(1,3-dichloro-2-propyl)phosphate (TDCPP) and triphenyl phosphate (TPhP) found at levels comparable to thresholds for aquatic toxicity. Thousands of man-made chemicals are found in Bay water, sediment, and organisms. For many of these, there
600-667: A major seaport . The Port of Oakland is one of the largest cargo ports in the United States, while the Port of Richmond and the Port of San Francisco provide smaller services. An additional crossing south of the Bay Bridge has long been proposed. San Francisco Bay is popular for sailors (boats, as well as windsurfing and kitesurfing ), due to consistent strong westerly/northwesterly thermally-generated winds – Beaufort force 6 (15–25 knots; 17–29 mph; 8–13 m/s)
700-577: A safe eating advisory for fish caught in the San Francisco Bay based on levels of mercury or PCBs found in local species. The San Francisco Bay Area Water Trail is a planned system of designated trailheads designed to improve non-motorized small boat access to the bay. The California Coastal Conservancy approved funding in March 2011 to begin implementation of the water trail. Kellersberger%27s Map The map can be seen here: 1854 Map of
800-727: A small, though busy, wharf by the bay. In 1866, Oakland's private College of California looked for a new site. It settled on a location north of Oakland along the foot of the Contra Costa Range (later called the Berkeley Hills) on Strawberry Creek , at an elevation of about 500 feet (150 m) above the bay, commanding a view of the Bay Area and the Pacific Ocean through the Golden Gate . According to
900-470: A statewide referendum that proposed moving the California state capital to Berkeley was defeated by a margin of about 33,000 votes. The city had named streets around the proposed capitol grounds for California counties. They bear those names today, a legacy of the failed referendum. On March 4, 1909, following public referendums, the citizens of Berkeley were granted a new charter by the State of California, and
1000-479: A vast stretch of land on the east shore of San Francisco Bay (the contra costa , "opposite shore") for a ranch, including that portion that now comprises the City of Berkeley. Luis Peralta named his holding " Rancho San Antonio ." The primary activity of the ranch was raising cattle for meat and hides, but hunting and farming were also pursued. Eventually, Peralta gave portions of the ranch to each of his four sons. What
1100-560: A widespread distribution in the bay, with uptake in the bay's phytoplankton and contamination of its sportfish. In January 1971, two Standard Oil tankers collided in the bay, creating an 800,000-U.S.-gallon (3,000,000-liter) oil spill disaster , which spurred environmental protection of the bay. In November 2007, a ship named COSCO Busan collided with the San Francisco–Oakland Bay Bridge and spilled over 58,000 U.S. gallons (220,000 liters) of bunker fuel , creating

No artifact survives of the Domingo or Vicente ranches, but their names survive in Berkeley street names (Vicente, Domingo, and Peralta). However, legal title to all land in the City of Berkeley remains based on the original Peralta land grant. The Peraltas' Rancho San Antonio continued after Alta California passed from Spanish to Mexican sovereignty after
1500-484: Is now called Drakes Bay . At the time, Drakes Bay went by the name Bahia de San Francisco and thus both bodies of water became associated with the name. Eventually, the larger, more important body of water fully appropriated the name San Francisco Bay . The first European to enter the bay is believed to have been the Spanish explorer Juan de Ayala , who passed through the Golden Gate on August 5, 1775, in his ship

1700-733: The Berkeley Oak Grove Protest began protesting construction of a new sports center annex to Memorial Stadium at the expense of a grove of oak trees on the UC campus. The protest ended in September 2008 after a lengthy court process. In 2007–2008, Berkeley received media attention due to demonstrations against a Marine Corps recruiting office in downtown Berkeley and a series of controversial motions by Berkeley's city council regarding opposition to Marine recruiting. ( See Berkeley Marine Corps Recruiting Center controversy .) During

One of them, Frederick Billings , thought of the lines of the Anglo-Irish Anglican Bishop George Berkeley , 'westward the course of empire takes its way,' and suggested that the town and college site be named for
1900-928: The Dumbarton Rail Bridge , the first bridge crossing San Francisco Bay. The first automobile crossing was the Dumbarton Bridge , completed in January 1927. More crossings were later constructed – the Carquinez Bridge in May 1927, the San Francisco–Oakland Bay Bridge in 1936, the Golden Gate Bridge in 1937, the Richmond–San Rafael Bridge in 1956, and the San Mateo–Hayward Bridge in 1967.

The town and other parts of the East Bay escaped serious damage, and thousands of refugees flowed across the Bay. Among them were most of San Francisco's painters and sculptors, who between 1907 and 1911 created one of the largest art colonies west of Chicago. Artist and critic Jennie V. Cannon described

#17327721735882200-729: The Mexican War of Independence . However, the advent of U.S. sovereignty after the Mexican–American War , and especially, the Gold Rush , saw the Peraltas' lands quickly encroached on by squatters and diminished by dubious legal proceedings. The lands of the brothers Domingo and Vicente were quickly reduced to reservations close to their respective ranch homes. The rest of the land was surveyed and parceled out to various American claimants ( See Kellersberger's Map ). Politically,
2300-597: The Russian–American Company entered San Francisco Bay in 1807 and again over 1810–1811. Led by the Russian Timofei Nikitich Tarakanov , these hunting raids probably wiped out sea otters in the bay. Thousands of sea otter skins were taken to Sitka, then Guangzhou (Canton), China, where they commanded a high price. The United States seized the region from Mexico during the Mexican–American War (1846–1848). On February 2, 1848,

California's Dungeness crab , California halibut , and Pacific salmon fisheries rely on the bay as a nursery. The few remaining salt marshes now represent most of California's remaining salt marsh, supporting a number of endangered species and providing key ecosystem services such as filtering pollutants and sediments from
2600-548: The San Carlos and moored in a bay of Angel Island now known as Ayala Cove. Ayala continued to explore the San Francisco Bay Area and the expedition's cartographer, José de Cañizares, gathered the information necessary to produce the first map of the area. A number of place names survive (anglicized) from that first map, including Point Reyes , Angel Island , Farallon Islands , and Alcatraz Island . Alaskan Native sea otter hunters using Aleutian kayaks and working for
2700-497: The San Francisco Bay . The bay was designated a Ramsar Wetland of International Importance on February 2, 2013, and the Port of Oakland on the bay is one of the busiest cargo ports on the west coast. The bay covers somewhere between 400 and 1,600 square miles (1,000–4,000 km ), depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands , and so on are included in the measurement. The main part of
2800-515: The Vietnam Day Committee . Berkeley is strongly identified with the rapid social changes, civic unrest, and political upheaval that characterized the mid-to-late 1960s. In that period, Berkeley—especially Telegraph Avenue —became a focal point for the hippie movement, which spilled over the Bay from San Francisco. Many hippies were apolitical drop-outs, rather than students, but in the heady atmosphere of Berkeley in 1967–1969 there
2900-401: The 1880s Berkeley had segregated housing and anti-Chinese laws. The area near the university became known for a time as East Berkeley. Due to the influence of the university, the modern age came quickly to Berkeley. Electric lights and the telephone were in use by 1888. Electric streetcars soon replaced the horsecar . A silent film of one of these early streetcars in Berkeley can be seen at
3000-552: The 20th century, the bay was subject to the 1940s Reber Plan , which would have filled in parts of the bay in order to increase industrial activity along the waterfront. In 1959, the United States Army Corps of Engineers released a report stating that if current infill trends continued, the bay would be as big as a shipping channel by 2020. This news created the Save the Bay movement in 1960, which mobilized to stop
3100-491: The Bay Area in recent times was spotted in 1983 off the San Mateo County coast in 1983. In 2001, bottlenose dolphins were first spotted east of the Golden Gate Bridge and confirmed by photographic evidence in 2007. Zooarcheological remains of bottlenose dolphins indicated that bottlenose dolphins inhabited San Francisco Bay in prehistoric times until at least 700 years before present, and dolphin skulls dredged from

During the Wisconsin Glaciation , between 15,000 and about 10,000 years ago, the basin which is now filled by the San Francisco Bay was a large river valley with small hills, channeling the Sacramento River through the Golden Gate Strait into the ocean. When the great ice sheets began to melt, around 11,000 years ago,
3400-952: The Police Department to avoid escalation of violence and to protect bystanders during protests. During a protest against bigotry and U.S. President Donald Trump in August 2017, self-described anti-fascist protesters attacked Trump supporters in attendance. Police intervened, arresting 14 people. Sometimes called " antifa ", these ‘anti-fascist’ activists were clad in black shirts and other black attire, while some carried shields and others had masks or bandanas hiding their faces to help them evade capture after street fighting. . These protests spanned February to September 2017 (See more at 2017 Berkeley Protests ). In 2019, protesters took up residence in People's Park against tree-chopping and were arrested by police in riot gear. Many activists saw this as

Some six million cubic yards (160 million cubic feet; 4.6 million cubic meters) of mud from the dredging was deposited at the western edge of Middle Harbor Shoreline Park to become a 188-acre (0.294 sq mi; 0.76 km ) shallow-water wetlands habitat for marine and shore life. Further dredging followed in 2011, to maintain the navigation channel. This dredging enabled
3600-521: The Town of Berkeley became the City of Berkeley. Rapid growth continued up to the Crash of 1929 . The Great Depression hit Berkeley hard, but not as hard as many other places in the U.S., thanks in part to the university. In 1916, Berkeley implemented single-family zoning as an effort to keep minorities out of white neighborhoods. This has been described as the first implementation of single-family zoning in
3700-434: The U.C. campus began to build up to the recognizable activism of the sixties. In the 1950s, McCarthyism induced the university to demand a loyalty oath from its professors, many of whom refused to sign the oath on the principle of freedom of thought. In 1960, a U.S. House committee ( HUAC ) came to San Francisco to investigate the influence of communists in the Bay Area. Their presence was met by protesters, including many from
3800-655: The U.S. was started by the Ecology Center in 1973. Styrofoam was banned in 1988. As the city leaned more and more Democratic, local politics became divided between "Progressives" and "Moderates". 1984 saw the Progressives take the majority for the first time. Nancy Skinner became the first UC Berkeley student elected to City Council. In 1986, in reaction to the 1984 election, a ballot measure switched Berkeley from at-large to district-based elections for city council. In 1983, Berkeley's Domestic Partner Task Force

On September 17, 1923, a major fire swept down the hills toward the university campus and the downtown section. Around 640 structures burned before a late-afternoon sea breeze stopped its progress, allowing firefighters to put it out. The next big growth occurred with
4000-607: The University of California and a high-demand housing market, Berkeley was relatively unaffected by the Great Recession . State budget cuts caused the university to increase the number of out-of-state and international students, with international enrollment, mostly from Asia, rising from 2,785 in 2007 to 5,951 in 2016. Since then, more international restaurants have opened downtown and on Telegraph Avenue , including East Asian chains such as Ippudo and Daiso . A wave of downtown apartment construction began in 1998. In 2006,

On March 25, 1853, Alameda County was created from a division of Contra Costa County, as well as from a small portion of Santa Clara County . The area that became Berkeley was then the northern part of the "Oakland Township" subdivision of Alameda County. During this period, "Berkeley" was mostly a mix of open land, farms, and ranches, with

Sailing ships enabled transportation between the bay and other parts of the world—and served as ferries and freighters within the bay and between the bay and inland ports, such as Sacramento and Stockton. These were gradually replaced by steam-powered vessels starting in the late 19th century. Several shipyards were established around
4500-628: The arrival of the largest container ship ever to enter the San Francisco Bay, the MSC Fabiola . Bay pilots trained for the visit on a simulator at the California Maritime Academy for over a year. The ship arrived drawing less than its full draft of 50 feet 10 inches (15.5 m) because it held only three-quarters of a load after its stop in Long Beach. San Francisco Bay was traversed by watercraft before
4600-401: The average depth of the bay is only as deep as a swimming pool—approximately 12 to 15 ft (4–5 m). Between Hayward and San Mateo to San Jose it is 12 to 36 in (30–90 cm). The deepest part of the bay is under and out of the Golden Gate Bridge, at 372 ft (113 m). In the late 1990s, a 12-year harbor-deepening project for the Port of Oakland began; it

The bay also has some of the highest levels of dissolved inorganic nitrogen known from any coastal water body, mostly originating from treated wastewater from Publicly owned treatment works . In other bays, such nutrient levels would likely lead to eutrophication , but historically, the bay has had less harmful algal blooms than other water bodies with similar nutrient concentrations. Potential explanations have included
7300-547: The largest religious studies institutions in the world. Berkeley is considered one of the most socially progressive cities in the United States. The site of today's City of Berkeley was the territory of the Chochenyo/Huchiun Ohlone people when the first Europeans arrived. Evidence of their existence in the area include pits in rock formations, which they used to grind acorns. wildflower seeds, grass seeds, and many different foods, including squirrel fat, and
7400-561: The late 19th century and again with the initiation of dredging by the US Army Corps of Engineers in the 20th century. Before about 1860, most bay shores (with the exception of rocky shores, such as those in Carquinez Strait; along Marin shoreline; Point Richmond; Golden Gate area) contained extensive wetlands that graded nearly invisibly from freshwater wetlands to salt marsh and then tidal mudflat. A deep channel ran through
7500-518: The mainline of the transcontinental railroad into Oakland was re-routed, putting the right-of-way along the bay shore through Ocean View. There was a strong prohibition movement in Berkeley at this time. In 1876, the state enacted the "mile limit law", which forbade sale or public consumption of alcohol within one mile (1.6 km) of the new University of California. Then, in 1899, Berkeley residents voted to make their city an alcohol-free zone. Scientists, scholars and religious leaders spoke vehemently of
7600-677: The major damage close to the bay in the Loma Prieta earthquake of 1989 occurred to structures on these areas. The Marina District of San Francisco, hard hit by the 1989 earthquake, was built on fill that had been placed there for the Panama-Pacific International Exposition , although liquefaction did not occur on a large scale. In the 1990s, San Francisco International Airport proposed filling in hundreds more acres to extend its overcrowded international runways in exchange for purchasing other parts of
7700-532: The nationwide Occupy Wall Street movement came to two Berkeley locations: on the campus of the University of California and as an encampment in Civic Center Park. During a Black Lives Matter protest on December 6, 2014, police use of tear gas and batons to clear protesters from Telegraph Avenue led to a riot and five consecutive days and nights of protests, marches, and freeway occupations in Berkeley and Oakland. Afterwards, changes were implemented by

The first European to see San Francisco Bay is likely N. de Morena who was left at New Albion at Drakes Bay in Marin County, California , by Sir Francis Drake in 1579 and then walked to Mexico. The first recorded European discovery of San Francisco Bay
8000-416: The presence of intensive "top-down control" from grazing clams like Potamocorbula , high sediment supply limiting light availability for the algae, and intensive tidal mixing. The occurrence of an unprecedented harmful algal bloom of Heterosigma akashiwo in 2022, resulting in mass fish deaths and anoxia, suggests that the mechanisms of control on algal growth may be eroding. The bay was once considered
8100-678: The rest of the nation, fueled by spillover from the San Francisco housing shortage and population growth. South and West Berkeley underwent gentrification , with some historically Black neighborhoods such as the Adeline Corridor seeing a 50% decline in Black / African American population from 1990 to 2010. In the 1990s, public television's Frontline documentary series featured race relations at Berkeley's only public high school, Berkeley High School . With an economy dominated by
8200-405: The rivers that settled in those parts of the bay that had little or no current. Later, wetlands and inlets were deliberately filled in, reducing the bay's size since the mid-19th century by as much as one third. Recently, large areas of wetlands have been restored, further confusing the issue of the bay's size. Despite its value as a waterway and harbor , many thousands of acres of marshy wetlands at
8300-463: The rivers, progressively eroding into finer and finer sediment, until it reached the bay system. Here some of it settled, eventually filling in Suisun Bay, San Pablo Bay, and San Francisco Bay, in decreasing order of severity. By the end of the 19th century, these " slickens " had filled in much of the shallow bay flats, raising the entire bay profile. New marshes were created in some areas. In
8400-896: The rivers. San Francisco Bay is recognized for protection by the California Bays and Estuaries Policy , with oversight provided by the San Francisco Estuary Partnership . Most famously, the bay is a key link in the Pacific Flyway . Millions of waterfowl annually use the bay shallows as a refuge. Two endangered species of birds are found here: the California least tern and the Ridgway's Rail . Exposed bay muds provide important feeding areas for shorebirds , but underlying layers of bay mud pose geological hazards for structures near many parts of
8500-572: The sea level started to rise rapidly, by about 1 inch per year. Melting glaciers in the Sierra Nevada washed huge amounts of sediment down the Sacramento and San Joaquin rivers, which accumulated on the shores of the bay, forming huge mudflats and marshes that supported local wildlife. By 5000 BC the sea level rose 300 feet (90 m), filling the valley with water from the Pacific. The Farallon Islands are what used to be hills along
8600-714: The shore line of San Francisco Bay at the time of the discovery of gold in California, January 24, 1848. Map reproduced above delineates old shore line. Placed by the Historic Landmarks committee, Native Sons of the Golden West , 1921." The bay became the center of American settlement and commerce in the Far West through most of the remainder of the 19th century. During the California Gold Rush (1848–1855), San Francisco Bay suddenly became one of
8700-554: The state law came into effect in 1995. For cities such as Berkeley, where rent control was already in place, the law limited the use of rent control to units built before the local rent-control law was enacted, i.e. 1980. During the 1970s and 1980s, activists increased their power in local government. This era also saw major developments in Berkeley's environmental and food culture. Berkeley's last Republican mayor, Wallace J. S. Johnson , left office in 1971. Alice Waters opened Chez Panisse in 1971. The first curbside recycling program in
8800-469: The streets and projects to improve social service provision for this demographic, homelessness has continued to be a significant problem in Berkeley. A culture of anti-establishment and sociopolitical activism marked the 1960s. The San Francisco Bay Area became a hotspot for hippie counterculture , and Berkeley became a haven for nonconformists and anarchists from all over the United States. Most public discourse around homelessness in Berkeley at this time

In 1876, a branch line of the Central Pacific Railroad , the Berkeley Branch Railroad , was laid from a junction with the mainline called Shellmound (now a part of Emeryville) into what is now downtown Berkeley . That same year,
9000-454: The university preparing to develop the park. The city of Berkeley has historically been a central location for homeless communities in the Bay Area. Since the 1930s, the city of Berkeley has fostered a tradition of political activism. The city has been perceived as a hub for liberal thought and action and it has passed ordinances to oust homeless individuals from Berkeley on multiple occasions. Despite efforts to remove unhoused individuals from

Finally, in 1964, the university provoked a massive student protest by banning distribution of political literature on campus. This protest became the Free Speech Movement . As the Vietnam War rapidly escalated in the ensuing years, so did student activism at the university, particularly that organized by
9200-521: The west and the Hayward Fault to the east, though the precise nature of this remains under study. About 560,000 years ago, a tectonic shift caused the large inland Lake Corcoran to spill out the central valley and through the Carquinez Strait , carving out sediment and forming canyons in what is now the northern part of the San Francisco Bay and Golden Gate strait . San Francisco Bay has been filled and emptied of sea water many times during
9300-434: The wetlands of the San Francisco Bay with a high salt tolerance. It needs native pickleweed , which is often displaced by invasive cordgrass, for its habitat. The seasonal range of water temperature in the bay is from January's 53 °F (12 °C) to September's 60 °F (16 °C) when measured at Fort Point , which is near the southern end of the Golden Gate Bridge and at the entrance to San Francisco Bay. For
9400-622: The world's great seaports, dominating shipping in the American West until the last years of the 19th century. The bay's regional importance increased further when the first transcontinental railroad was connected to its western terminus at Alameda on September 6, 1869. The terminus was switched to the Oakland Long Wharf two months later on November 8, 1869. In 1910, the Southern Pacific railroad company built

An iconic event in the Berkeley Sixties scene was a conflict over a parcel of university property south of the contiguous campus site that came to be called " People's Park ". The battle over the disposition of People's Park resulted in a month-long occupation of Berkeley by the National Guard on orders of then-Governor Ronald Reagan . In
9700-399: Was established, which in 1984 made policy recommendation to the school board, which passed domestic partner legislation. The legislation became a model for similar measures nationwide. In 1995, California's Costa–Hawkins Act ended vacancy control, allowing rents to increase when a tenant moved out. Despite a slow down in 2005–2007, median home prices and rents remain dramatically higher than
9800-646: Was largely completed by September 2009. Previously, the bay waters and harbor facilities only allowed for ships with a draft of 46 ft (14 m), but dredging activities undertaken by the United States Army Corps of Engineers in partnership with the Port of Oakland succeeded in providing access for vessels with a 50-foot (15 m) draft. Four dredging companies were employed in the US$ 432 ;million project, with $ 244 million paid for with federal funds and $ 188 million supplied by
9900-409: Was on November 4, 1769, when Spanish explorer Gaspar de Portolá , unable to find the Port of Monterey , continued north close to what is now Pacifica and reached the summit of the 1,200-foot-high (370 m) Sweeney Ridge , now marked as the place where he first sighted San Francisco Bay. Portolá and his party did not realize what they had discovered, thinking they had arrived at a large arm of what
10000-473: Was synthesized utilizing the 60-inch (1.5 m) cyclotron at UC Berkeley, and named in 1949, in recognition of the university, thus placing the city's name in the list of elements. During the 1940s, many African Americans migrated to Berkeley. In 1950, the Census Bureau reported Berkeley's population as 11.7% black and 84.6% white. The postwar years brought moderate growth to the city, as events on
