Clark County, Nevada

Clark County is a county located in the U.S. state of Nevada. The land area of Clark County is 8061 sqmi, or roughly the size of New Jersey. As of the 2020 census, the population was 2,265,461. Most of the county population resides in the Las Vegas Census County Divisions, which has 2,196,623 people as of the 2020 Census. It is by far the most populous county in Nevada, and the 11th-most populous county in the United States. It covers 7% of the state's land area but holds 73% of the state's population, making Nevada the most centralized state in the United States.

History
Las Vegas, the state's most populous city, has been the county seat since its establishment. The county was formed by the Nevada Legislature by splitting off a portion of Lincoln County on February 5, 1909, and was organized on July 1, 1909. The Las Vegas Valley, a 600 sqmi basin, includes Las Vegas and other major cities and communities such as North Las Vegas, Henderson, and the unincorporated community of Paradise.

Native Americans lived in the Las Vegas Valley beginning over 10,000 years ago. Paiutes moved into the area as early as AD 700. Previously part of the Mexican Territory of Alta California, the Clark County lands were subsequently traversed by American beaver trappers. Word of their journeys inspired the New Mexican merchant Antonio Armijo in 1829 to establish the first route for mule trains and herds of livestock from Nuevo Mexico to Alta California through the area, along the Virgin and Colorado Rivers. Called the Armijo Route of the Old Spanish Trail, the route was later modified into the Main Route by the passing merchants, trappers, drovers, Ute raiders and settlers over the years by moving to a more direct route. In Clark County it was northward away from the Colorado to a series of creeks, waterholes and springs like those at Las Vegas, to which John C. Frémont added Frémont's Cutoff on his return from California to Utah in 1844.

What is now Clark County was acquired by the United States during the Mexican–American War, becoming part of the northwestern corner of New Mexico Territory. In 1847, Jefferson Hunt and other Mormon Battalion members returning to Salt Lake City from Los Angeles pioneered a wagon route through the County that became the Mormon Road. In 1849, this road became known as the "Southern Route", the winter route of the California Trail from Salt Lake City to Los Angeles during the California Gold Rush. By the mid-1850s, the route now known as the Salt Lake Road in California, and the California Road in Utah Territory, was a wagon trade route between the two. In the mid-1850s, Mormons established a Mormon Fort at Las Vegas. In the 1860s, Mormon colonies were established along the Virgin and Muddy Rivers.

All of the county was part of Mohave County, Arizona Territory, when that Territory was formed in 1863, before Nevada became a state. In 1865, it became part of Pah-Ute County, Arizona Territory. The part of Pah-Ute County north and west of the Colorado River was assigned to the new State of Nevada in 1866; however, Arizona territory fought the division until 1871. Pah-Ute County became part of Lincoln County and the westernmost part became the southernmost part of Nye County.

Clark County was named for William A. Clark, a Montana copper magnate and Democratic U.S. Senator. Clark was largely responsible for construction of the San Pedro, Los Angeles and Salt Lake Railroad through the area, contributing to the region's early development. Clark County is a major tourist destination with 150,000 hotel rooms. The Las Vegas Strip, home to many famous hotel-casinos, is not within the City of Las Vegas limits, but in unincorporated Paradise. It is, however, in the Las Vegas Valley.

Clark County is geographically coextensive with the Las Vegas MSA, a metropolitan statistical area designated by the Office of Management and Budget and used by the United States Census Bureau and other agencies for statistical purposes. Over time and influenced by climate change, droughts in Southern Nevada have been increasing in frequency and severity, putting a further strain on Clark County's and Las Vegas's water security.

Geography
The Colorado River forms the county's southeastern boundary, with Hoover Dam forming Lake Mead along much of its length. The lowest point in the state of Nevada is on the Colorado River just south of Laughlin in Clark County, where it flows out of Nevada into California and Arizona. Greater Las Vegas is a tectonic valley, surrounded by four mountain ranges, with nearby Mount Charleston being the highest elevation at 11918 ft, located to the northwest. Other than the forests on Mount Charleston, the geography in Clark County is a desert. Creosote bushes are the main native vegetation, and the mountains are mostly rocky with little vegetation. The terrain slopes to the south and east. The county has an area of 20879 km2, of which 20438 km2 is land and 441 km2 (2.1%) is water.

Environmental factors
Clark County has diverse desert flora and fauna, including higher-elevation mountain areas, the desert floor, and the Colorado River/Lake Mead ecosystems. Variations in diurnal temperature as well as seasonal swings in temperature create demanding adaptation elements on the species of this county. Population expansion, especially since 1970, has placed additional pressure on species in the area.

Correspondingly, air quality levels prior to the 1960s were in a favorable range, but the proliferation of automobiles with the human population expansion created circumstances where some federal air quality standards were violated starting in the 1980s.

To plan for the wave of development forecast by 1980, Clark County embarked on a regional environmental impact assessment funded by a federal Section 208 program, with Sedway Cooke conducting the planning work and Earth Metrics performing environmental analysis. This endeavor projected population growth, land use changes and environmental impacts.

To prevent the loss of federal funds due to unacceptable dust levels in the Las Vegas valley, in 2003 the Nevada Air Quality Management division (under direction of Clark County officials) created the "Don't Be a Dusthole" campaign. The campaign successfully raised awareness of dust pollution in the Las Vegas Valley, quantifiably reducing pollutants and preserving ongoing federal funding.

The Apex Landfill, at 2200 acre, is the nation's largest landfill. Republic Services owns and operates the landfill.

Earthquake hazards
Nevada is the third most seismically active state in the U.S. (after Alaska and California); the United States Geological Survey has estimated that over the next 50 years, Clark County has a 10–20% chance of a (moment magnitude) M6.0 or greater earthquake occurring within 50 km of Las Vegas.

Government
The Clark County Commission consists of seven members who are elected to serve staggered four-year terms in biennial partisan elections. The commission members elect a chairman, who chairs their meetings. A hired county manager handles day-to-day operations under direction of the commission. The county's unincorporated towns also have appointed boards that provide advice to the commission.

The county operates out of the Clark County Government Center in the City of Las Vegas. The building is unusual in shape, and includes an outdoor amphitheater for concerts and other events.

The Las Vegas Metropolitan Police Department provides most law enforcement services in the county, including operation of the county's central jail, the Clark County Detention Center (CCDC). The present department was created in 1973 when the Clark County Sheriff's Department merged with the Las Vegas Police Department.

Other entities with police forces include University of Nevada, Las Vegas, the Clark County School District, and cities such as Henderson, Mesquite, Boulder City and North Las Vegas. The Clark County Park Police is responsible for all of the parks operated by the county and some selected special venues, such as the Clark County Amphitheater, Clark County Archery Range, and the Desert Rose Golf Course.

The Regional Justice Center replaced the Clark County Courthouse in 2005, and is about 3 blocks from downtown Fremont Street, at 200 Lewis Avenue.

Courts
The Clark County Justice Courts are divided into eleven townships. Each elects its own justices of the peace for limited jurisdiction cases and a constable. They do not correspond with city boundaries. The Las Vegas Justice Court Township the city of Las Vegas  and the unincorporated towns of Blue Diamond, Cactus Springs, Enterprise, Indian Springs, Mount Charleston, Paradise, Spring Valley, Summerlin South, Sunrise Manor (partially in North Las Vegas Township), Whitney (partially in Henderson Township) and Winchester. The city of Las Vegas has a separate municipal court for traffic and criminal misdemeanor offenses that occur within the city's incorporated boundaries.

The Clark County Marshal's Office provides security for Clark County courts. The Marshal is head of the office, while Deputy Marshals act as bailiffs for the court.

Voter registration
According to the Secretary of State's office, Independents comprise a plurality of registered voters in Clark County.

Politics
With nearly three-quarters of Nevada's population, Clark County plays a significant role in determining statewide Nevada elections as well the winner of the state's electoral votes in presidential elections. At the presidential level, the county, like most urban counties nationwide, leans Democratic. The last Republican to carry the county was George H. W. Bush in 1988. However, it is somewhat less Democratic than many other urban counties; the GOP candidate has received at least 39 percent of the vote in every election since 1996. This Democratic trend predates the county's explosive growth in the second half of the 20th century. Republican presidential candidates have only won the county six times from 1912 to the present day, all coming in national landslides where the Republican won over 400 electoral votes.

At the statewide level, however, the county is more of a swing county, with several Republican gubernatorial candidates and U.S. Senators winning the county since the late 1980s. The last Republican senator to win the county was John Ensign in his 2006 victory, even as Jim Gibbons lost it in his gubernatorial win over Dina Titus that year. Both Kenny Guinn and Brian Sandoval carried the county in both gubernatorial terms they won, however.

In 2018, Dean Heller carried 15 of Nevada's 17 county-level jurisdictions in his bid for a second full term in the U. S. Senate. However, Democratic challenger Jacky Rosen won Clark by over 92,000 votes, almost double her statewide margin of 48,000 votes. In that year's gubernatorial election, Democrat Steve Sisolak lost 15 out of 17 county-level jurisdictions, but won Clark by enough of a margin to get the victory. Since 2008, the Democratic presidential candidate has won Clark by more than enough votes to carry Nevada.

The city of Las Vegas itself leans Democratic, as do the communities of Paradise, Spring Valley and Enterprise. The city of North Las Vegas and the communities of Sunrise Manor, Winchester and Whitney are more strongly Democratic, while the city of Henderson and the Summerlin South community have a Republican lean. Boulder City, where gambling is prohibited, leans Republican. Outside Las Vegas Valley, the county leans Republican.

Regional agencies
The Clark County Regional Flood Control District (CCRFCD) was created in 1985 by the Nevada Legislature allowing Clark County to provide broad solutions to flooding problems.
