San Bernardino County (/sæn ˌbɜːrnəˈdiːnoʊ/ ^ⓘ SAN BUR-nə-DEE-noh), officially the County of San Bernardino and sometimes abbreviated as S.B. County,^[9] is a county located in the southern portion of the U.S. state of California, and is located within the Inland Empire area. As of the 2020 U.S. Census, the population was 2,181,654,^[10] making it the fifth-most populous county in California and the 14th-most populous in the United States. The county seat is San Bernardino.^[11]

While included within the Greater Los Angeles area, San Bernardino County is included in the Riverside–San Bernardino–Ontario metropolitan statistical area.

With an area of 20,105 square miles (52,070 km²), San Bernardino County is the largest county in the contiguous United States by area, although some of Alaska's boroughs and census areas are larger. The county is close to the size of West Virginia.

This vast county stretches from where 93% of the county population resides in three Census County Divisions (Fontana, San Bernardino, and Victorville-Hesperia), counting 1,793,186 people as of the 2010 Census, covering 1,730 square miles (4,500 km²), across the thinly populated deserts and mountains. It spans an area from south of the San Bernardino Mountains in San Bernardino Valley, to the Nevada border and the Colorado River.

With a 2020 population that was 53.7% Hispanic, it is California's most populous majority-Hispanic county and the second-largest nationwide.^[12]

History

Indigenous

The indigenous peoples that resided in what is now San Bernardino County were primarily the Taaqtam (Serrano) and ʔívil̃uqaletem (Cahuilla) peoples who lived in the San Bernardino Valley and the San Bernardino Mountains; the Chemehuevi and the Kawaiisu peoples who lived in the Mojave Desert region; and the 'Aha Makhav (Mohave) and the Piipaash (Maricopa) peoples who lived along the Colorado River. These groups established various villages and settlements throughout the region that were interconnected by a series of extensive trails.^[13]^[14]^[15]

Wa'aachnga was a major Tongva village site, also occupied by the Serrano and Cahuilla, located near what is now the city of San Bernardino. The village was part of an extensive trade network along the Mohave Trail that connected villages in San Bernardino County from the Colorado River to the Los Angeles Basin.^[16]^[17] Wá'peat was a Desert Serrano village located near what is now the city of Hesperia. It was part of a series of villages located along the Mojave River.^[18] By the late 1700s, villages in the area were being increasingly encroached upon by Spanish soldiers and missionaries, who were coming into the region from Mission San Gabriel.^[19]^[14]

Colonial period

Spanish Missionaries from Mission San Gabriel Arcángel established a church at the village of Wa'aachnga, which would be renamed Politania in 1810.^[14] Father Francisco Dumetz named the church San Bernardino on May 20, 1810, after the feast day of St. Bernardino of Siena. The Franciscans also gave the name San Bernardino to the snowcapped peak in Southern California, in honor of the saint and it is from him that the county derives its name.^[20] In 1819, they established the San Bernardino de Sena Estancia, a mission farm in what is now Redlands.

Following Mexican independence from Spain in 1821, Mexican citizens were granted land grants to establish ranchos in the area of the county. Rancho Jurupa in 1838, Rancho Cucamonga and El Rincon in 1839, Rancho Santa Ana del Chino in 1841, Rancho San Bernardino in 1842 and Rancho Muscupiabe in 1844.

Agua Mansa was the first town in what became San Bernardino County, settled by immigrants from New Mexico on land donated from the Rancho Jurupa in 1841.

Establishment

Following the purchase of Rancho San Bernardino, and the establishment of the town of San Bernardino in 1851 by Mormon colonists, San Bernardino County was formed in 1853 from parts of Los Angeles County. Some of the southern parts of the county's territory were given to Riverside County in 1893.

Geography

The Arrowhead natural feature is the source of many local names and icons, such as Lake Arrowhead and the county's seal.

Central Joshua Tree with the mountains of Joshua Tree National Park on the horizon.

According to the U.S. Census Bureau, the county has a total area of 20,105 square miles (52,070 km²), of which 20,057 square miles (51,950 km²) is land and 48 square miles (120 km²) (0.2%) is water.^[21] It is the largest county by area in California and the largest in the United States (excluding boroughs in Alaska).^[22] It is slightly larger than the states of New Jersey, Connecticut, Delaware and Rhode Island combined, and is also slightly larger than Switzerland. It borders both Nevada and Arizona.

The bulk of the population, nearly two million, live in the roughly 480 square miles south of the San Bernardino Mountains adjacent to Riverside and in the San Bernardino Valley in the southwestern portion of the county. About 390,000 residents live just north of the San Bernardino Mountains, in and around the roughly 280 square-mile area that includes the Victor Valley. Roughly another 100,000 people live scattered across the rest of the sprawling county.

The Mojave National Preserve covers some of the eastern desert, especially between Interstate 15 and Interstate 40. The desert portion also includes the cities of Needles next to the Colorado River and Barstow at the junction of Interstate 15 and Interstate 40. Trona is at the northwestern part of the county, west of Death Valley. This national park, mostly within Inyo County, also has a small portion of land within San Bernardino County. The largest metropolitan area in the Mojave Desert part of the county is the Victor Valley, with the incorporated localities of Adelanto, Apple Valley, Hesperia, and Victorville. Further south, a portion of Joshua Tree National Park overlaps the county near the High Desert area, in the vicinity of Twentynine Palms. The remaining towns make up the remainder of the High Desert: Pioneertown, Yucca Valley, Joshua Tree, Landers, and Morongo Valley.

The mountains are home to the San Bernardino National Forest, and include the communities of Crestline, Lake Arrowhead, Running Springs, Big Bear City, Forest Falls, and Big Bear Lake.

The San Bernardino Valley is at the eastern end of the San Gabriel Valley. The San Bernardino Valley includes the cities of Ontario, Chino, Chino Hills, Upland, Fontana, Rialto, Colton, Grand Terrace, Montclair, Rancho Cucamonga, San Bernardino, Loma Linda, Highland, Redlands, and Yucaipa.

National protected areas

More than 80% of the county's land is owned by the federal government.^[23] There are at least 35 official wilderness areas in the county that are part of the National Wilderness Preservation System. This is the largest number of any county in the United States (although not the largest in total area). The majority are managed by the Bureau of Land Management, but some are integral components of the above listed national protected areas. Most of these wilderness areas lie entirely within the county, but a few are shared with neighboring counties (and two of these are shared with the neighboring states of Arizona and Nevada).

Except as noted, these wilderness areas are managed solely by the Bureau of Land Management and lie within San Bernardino County:

Politics

San Bernardino County is a county in which candidates from both major political parties have won in recent elections. Republican Donald Trump carried the country in 2024, flipping it for the first time in a presidential race since 2004. In past presidential elections, Democrat Joe Biden carried the county by a majority and by double digits as well as Hillary Clinton in 2016. The Democratic Party also carried the county in 2008 and 2012, when Barack Obama won majorities of the county's votes, and in 1992 and 1996, when Bill Clinton won pluralities. Republican George W. Bush took the county in 2000 by a plurality and in 2004 by a majority. The county is split between heavily Latino, middle-class, and Democratic areas and wealthier conservative areas. The heavily Latino cities of Ontario and San Bernardino went for John Kerry in 2004 but with a relatively low voter turnout. In 2006, San Bernardino's population exceeded 201,000, and in 2004, only 42,520 votes were cast in the city; that same year, strongly Republican Rancho Cucamonga had over 145,000 residents, of whom 53,054 voted.

In the 1980s, Northern San Bernardino County proposed to create Mojave County due to the abysmal service levels the county provided. Ultimately, the vote for county secession failed. The proposed county was from the Cajon Pass to the city of Needles.^[52]

In 1998, County administrator James Hlawek resigned after being subject to an FBI investigation for bribery, but only after Harry Mays, county Treasurer-Tax Collector Thomas O'Donnell, County Investment Officer Sol Levin and three businessmen had agreed to plead guilty to federal bribery charges.^[53]^[54]

In 2004, County Supervisor Geral Eaves Pleaded guilty to bribery for accepting gifts from businesses for allowing billboards on county land.^[55]

On November 4, 2008, San Bernardino County voted 67% for Proposition 8, which amended the California Constitution to ban same-sex marriages.^[56]

From 2004 to 2016, the county was embroiled in a corruption scandal over the Colonies housing development in Upland with real estate developer Jeff Burum. The scandal resulted in $102 million being paid to Burum's real estate company. Supervisor Bill Postmus pleaded guilty to 10 felonies in regard to his previous post as county assessor. In 2020, Burum sued the county again and the county reached for a $69 million settlement. 2022, the county's insurance company, Ironside, balked at paying the settlement, claiming that the county willfully "retaliate[d] against the Colonies II Plaintiffs as part of a decades-long dispute over land and water rights in Upland, California, culminating in a malicious prosecution of Burum."^[57]^[58]^[59]^[60]^[61]

In 2020, voters approved Measure K, which limited county supervisors to one term instead of three, while reducing pay from 250 thousand dollars to 60 thousand dollars. County Supervisors appealed the decision, only to lose in the state's appeals court.^[62]^[63]^[64]^[65]^[66] By 2022, term limits were restored and pay was restored to 80% of the annual base compensation for San Bernardino Superior Court judges under a supervisor lead ballot measure^[67]^[68]^[69]

In 2022, The Board of supervisors were pushed by a major supervisor campaign contributor Jeff Burum to vote for secession from the State of California to form the state of Empire.^[70]^[71]^[72]^[73]^[74]

In 2023, San Bernardino County Chief Executive Officer Leonard X. Hernandez resigned, claiming urgent family health issues,^[75] after being accused of having an affair with a county employee. After the accustation came out, the county placed Hernandez on Leave.^[76]^[77] After Hernandez resigned, Hernandez still got paid for one year after his departure.^[78]

Environmental quality

California Attorney General Jerry Brown sued the county in April 2007 under the state's environmental quality act for failing to account for the impact of global warming in the county's 25-year growth plan, approved in March. The Center for Biological Diversity, the Sierra Club and the Audubon Society also sued in a separate case. According to Brendan Cummings, a senior attorney for the plaintiffs: "San Bernardino has never seen a project it didn't like. They rubber-stamp development. It's very much of a frontier mentality." The plaintiffs want the county to rewrite its growth plan's environmental impact statement to include methods to measure greenhouse gases and take steps to reduce them.^[107]

According to county spokesman David Wert, only 15% of the county is controlled by the county^{[clarification needed]}; the rest is cities and federal and state land. However, the county says it will make sure employment centers and housing are near transportation corridors to reduce traffic and do more to promote compact development and mass transit. The county budgeted $325,000 to fight the lawsuit.^[107]

The state and the county reached a settlement in August 2007.^[108] The county agreed to amend its general plan to include a Greenhouse Gas Emissions Reduction Plan, including an emission inventory and reduction targets. According to the LA Times in 2015, San Bernardino County had the highest levels of ozone in the United States, averaging 102 parts per billion.^[109]
