Los Angeles County is one of the original counties of California, created at the time of statehood in 1850. [8] The county originally included parts of what are now Kern, San Bernardino, Riverside, Inyo, Tulare, Ventura, and Orange counties. In 1851 and 1852, Los Angeles County stretched from the coast to the state line of Nevada. [9] As the population increased, sections were split off to organize San Bernardino County in 1853, Kern County in 1866, and Orange County in 1889.

Before the 1870s, Los Angeles County was divided into townships (many of which were amalgamations of one or more old ranchos): [10]

Location

As shown by the map below, Los Angeles County is bordered on the north by Kern County, on the east by San Bernardino County, on the southeast by Orange County, on the south by the Pacific Ocean, and on the west by Ventura County.

[14] Los Angeles County borders 70 miles (110 km) of coast on the Pacific Ocean and encompasses mountain ranges, valleys, forests, islands, lakes, rivers, and desert. The Los Angeles River, Rio Hondo, Ballona Creek, the San Gabriel River and the Santa Clara River flow in Los Angeles County, while the primary mountain ranges are the Santa Monica Mountains and the San Gabriel Mountains. The western extent of the Mojave Desert begins in the Antelope Valley, in the northeastern part of the county.

Most of the population of Los Angeles County resides in the south and southwest, with major population centers in the Los Angeles Basin, San Fernando Valley, and San Gabriel Valley. Other population centers are found in the Santa Clarita Valley, Pomona Valley, Crescenta Valley and Antelope Valley.

The county is divided west-to-east by the San Gabriel Mountains, which are part of the Transverse Ranges of southern California, and are contained mostly within the Angeles National Forest. Most of the county's highest peaks are in the San Gabriel Mountains, including Mount San Antonio 10,068 feet (3,069 m) at the Los Angeles–San Bernardino county lines, Mount Baden-Powell 9,399 feet (2,865 m), Mount Burnham 8,997 feet (2,742 m) and Mount Wilson 5,710 feet (1,740 m). Several lower mountains are in the northern, western, and southwestern parts of the county, including the San Emigdio Mountains, the southernmost part of Tehachapi Mountains and the Sierra Pelona Mountains.

Government

The Government of Los Angeles County is defined and authorized under the California Constitution, California law and the Charter of the County of Los Angeles. [50] Much of the Government of California is in practice the responsibility of local governments such as the Government of Los Angeles County.

The county's voters elect a governing five-member Los Angeles County Board of Supervisors. The small size of the board means each supervisor represents over 2 million people. The board operates in a legislative, executive, and quasi-judicial capacity. As a legislative authority, it can pass ordinances for the unincorporated areas (ordinances that affect the whole county, like posting of restaurant ratings, must be ratified by the individual city). As an executive body, it can tell the county departments what to do, and how to do it. As a quasi-judicial body, the Board is the final venue of appeal in the local planning process, and holds public hearings on various agenda items.

As of 2020, the Board of Supervisors oversees a $35.5 billion annual budget and over 112,000 employees. [51] The county government is managed on a day-to-day basis by a chief executive officer and is organized into many departments, each of which is enormous in comparison to equivalent county-level (and even many state-level) departments anywhere else in the United States. Some of the larger or better-known departments include:

The Los Angeles County Metropolitan Transportation Authority, despite its name, is not a County department. Technically it is a state-mandated county transportation commission that also operates bus and rail.

In the United States House of Representatives, Los Angeles County is split between 17 congressional districts. [57] In the California State Senate, Los Angeles County is split between 13 legislative districts. [58] In the California State Assembly, Los Angeles County is split between 24 legislative districts. [59]

On November 4, 2008, Los Angeles County was almost evenly split over Proposition 8, which amended the California Constitution to ban same-sex marriages. The county voted for the amendment 50.04% with a margin of 2,385 votes. [60]

The Los Angeles County Superior Court is the county's court of general jurisdiction, while the U.S. District Court for the Central District of California may hear cases where federal jurisdiction is present. Both are headquartered in a large cluster of government buildings in the city's Civic Center.

Historically, the courthouses were county-owned buildings that were maintained at county expense, which created significant friction since the trial court judges, as officials of the state government, had to lobby the county Board of Supervisors for facility renovations and upgrades. In turn, the state judiciary successfully persuaded the state Legislature to authorize the transfer of all courthouses to the state government in 2008 and 2009 (so that judges would have direct control over their own courthouses). Courthouse security is still provided by the county government under a contract with the state.

Unlike the largest city in the United States, New York City, all of the city of Los Angeles and most of its important suburbs are located within a single county. As a result, both the county superior court and the federal district court are respectively the busiest courts of their type in the nation. [61] [62]

Many celebrities have been seen in Los Angeles courts. In 2003, the television show Extra (based in nearby Glendale) found itself running so many reports on the legal problems of local celebrities that it spun them off into a separate show, Celebrity Justice.

State cases are appealed to the Court of Appeal for the Second Appellate District, which is also headquartered in the Civic Center, and then to the California Supreme Court, which is headquartered in San Francisco but also hears argument in Los Angeles (again, in the Civic Center). Federal cases are appealed to the Court of Appeals for the Ninth Circuit, which hears them at its branch building in Pasadena. The court of last resort for federal cases is the U.S. Supreme Court in Washington, D.C.

Ecology

Many introduced species, such as this Indian peafowl, adapt readily to urban living and Los Angeles County's mild climate. Arcadia Peacock (cropped).jpg
Many introduced species, such as this Indian peafowl, adapt readily to urban living and Los Angeles County's mild climate.

According to the authors of Wild L.A., a book about urban biodiversity, "Los Angeles is the birdiest county in the country with over 500 recorded species." L.A.'s amenable climate supports a large number of introduced, tropical and migratory species. [68] Because of the county's wide range of biomes it is possible to see desert bighorn sheep and green sea turtles in the same day, without crossing the county line. [68] The range of habitats in the county is "greater than in many states, with mountains, wetlands, desert, ocean, meadows and chaparral, each with its own endemic species." [69] There are at least 100 species of trees, and 1000 species of non-native plants, in the urban areas of the county. [70] Charismatic biodiversity indicator species native to the area include three species of amphibian (Baja California chorus frog, black-bellied slender salamander, western toad), 14 species of bird (acorn woodpecker, California quail, canyon wren, cinnamon teal, great blue heron, great horned owl, greater roadrunner, hooded merganser, Northern harrier, red-tailed hawk, red-winged blackbird, spotted towhee, western bluebird, western meadowlark), nine kinds of invertebrates (Behr's metalmark, bramble green hairstreak, bumblebees, El Segundo blue butterfly, harvester ants, Lorquin's admiral, North American Jerusalem crickets, Sara orangetip, velvet ants), five mammals (bobcat, dusky footed woodrat, gray fox, mountain lion, mule deer), and six reptiles (California kingsnake, coachwhip snake, gopher snake, side-blotched lizard, western pond turtle, western rattlesnake). [71] Any observations of these species within the county are considered ecologically significant indicators of ecosystem health and may be documented using the iNaturalist app. [72] [73]

Venice Beach is a popular attraction whose Muscle Beach used to attract throngs of tourists admiring "hardbodies". Today, it is more arts-centered. Santa Monica's pier is a well known tourist spot, famous for its Ferris wheel and bumper car rides, which were featured in the introductory segment of the television sitcom Three's Company . Further north in Pacific Palisades one finds the beaches used in the television series Baywatch . [81] The fabled Malibu, home of many film and television stars, lies west of it.

In the mountain, canyon, and desert areas one may find Vasquez Rocks Natural Area Park, where many old Westerns were filmed. Mount Wilson Observatory in the San Gabriel Mountains is open for the public to view astronomical stars from its telescope, now computer-assisted. Many county residents find relaxation in water skiing and swimming at Castaic Lake Recreation Area – the county's largest park by area – as well as enjoying natural surroundings and starry nights at Saddleback Butte State Park in the eastern Antelope Valley – California State Parks' largest in area within the county. The California Poppy Reserve is located in the western Antelope Valley and shows off the State's flower in great quantity on its rolling hills every spring.

Rail

Los Angeles is a major freight-railroad transportation center, largely due to the large volumes of freight moving in and out of the county's sea port facilities. The ports are connected to the downtown rail yards and to the main lines of Union Pacific and Burlington Northern Santa Fe headed east via a grade-separated, freight rail corridor known as the Alameda Corridor.

Passenger rail service is provided in the county by Amtrak, Los Angeles Metro Rail and Metrolink.

Amtrak has the following intercity Amtrak service at Union Station in the city of Los Angeles:

Union Station is also the primary hub for Metrolink commuter rail, which serves much of the Greater Los Angeles Area.

Light rail, subway (heavy rail), and long-distance bus service are all provided by the Los Angeles County Metropolitan Transportation Authority (Metro). Other smaller regional transit agencies that provide public transit to specific regions of Los Angeles County include LADOT, Long Beach Transit, Montebello Bus Lines, Norwalk Transit, Santa Monica's Big Blue Bus serving the western LA region, Santa Clarita Transit, Torrance Transit, Glendale Beeline, Foothill Transit serving the San Gabriel Valley region, and the Antelope Valley Transit Authority serving the Lancaster and Palmdale area in the Antelope Valley region.

Sea

The county's two main seaports are the Port of Los Angeles and the Port of Long Beach. Together they handle over a quarter of all container traffic entering the United States, making the complex the largest and most important port in the country, and the third-largest port in the world by shipping volume.

The Port of Los Angeles is the largest cruise ship center on the West Coast, handling more than 1 million passengers annually.

The Port of Long Beach is home to the Sea Launch program, which uses a floating launch platform to insert payloads into orbits that would be difficult to attain from existing land-based launch sites.

Catalina Express ferries link the Catalina Island city of Avalon to the mainland at San Pedro and Long Beach, as well as Dana Point in Orange County.
