El Dorado County, California

What is now known as El Dorado County has been home to the Maidu, Nisenan, Washoe, and Miwok Indigenous American nations for centuries. The region became famous for being the site of the 1848 discovery that sparked the California Gold Rush. As a result, the name "El Dorado" was derived from the Spanish word for, "The Gilded One."^[7] The County of El Dorado was one of California's original 27 counties created effective February 18, 1850 (the number has risen to 58 today). Its name is derived from the Spanish meaning "the gilded/golden".^[8]

The final segments of the Pony Express mail route ran through El Dorado County until its replacement with the telegraph service in 1861; U.S. Highway 50 follows the Pony Express route today.

The Caldor Fire started on August 14, 2021, near Little Mountain, south of Pollock Pines in El Dorado County,^[9] about two miles East of Omo Ranch and four miles south of Grizzly Flats.^[10][11] It initially burned slowly, but exploded in size on August 16 due to high winds. By the night of August 16 it was 6,500 acres (2,600 ha).^[12] On August 17 the fire grew to 30,000 acres (12,000 ha) as it expanded rapidly north and east, crossing the North Fork Cosumnes River and approaching Sly Park Reservoir. By August 20 the fire had burned nearly to Highway 50, forcing a closure of the highway.^[13] Over the next few days, the fire crossed Highway 50 in the vicinity of Kyburz. Starting on August 27 winds drove the fire rapidly east towards the Lake Tahoe Basin. By August 30, it had reached Echo Summit, less than 5 miles (8.0 km) from South Lake Tahoe.

There are only two municipalities in El Dorado County: Placerville and South Lake Tahoe.^[14]

The El Dorado County Sheriff provides court protection, county jail administration, and coroner service for all of the county and provides patrol and detective services for the unincorporated areas of the county. Incorporated cities Placerville, population 11,000, has a municipal police department, as does South Lake Tahoe, population 22,000.

According to the U.S. Census Bureau, the county has a total area of 1,786 square miles (4,630 km²), of which 1,708 square miles (4,420 km²) is land and 78 square miles (200 km²) (4.4%) is water.^[15]

The county, owing to its location in the Sierra Nevada, consists of rolling hills and mountainous terrain. The northeast corner is in the Lake Tahoe Basin (part of the Great Basin), including a portion of the lake itself. Across the Sierra crest to the west lies the majority of the county, referred to as the "western slope." A portion of Folsom Lake is in the northwest corner of the county.

Much of the county is public land. The Eldorado National Forest comprises a significant portion (approximately 43%) of the county's land area, primarily on the western slope. The Lake Tahoe Basin Management Unit, formerly part of the Eldorado and two other National Forests, manages much of the land east of the crest. The Pacific Crest Trail runs through the eastern part of the county, along or roughly paralleling the Sierra crest. The county is home to the Desolation Wilderness, a popular destination for hiking, backpacking, and fishing.

The vast majority of the population lives in a narrow strip along U.S. Route 50, with the majority living between El Dorado Hills and Pollock Pines. The remainder resides in the South Lake Tahoe area, and in various dispersed rural communities.

Note: the US Census treats Hispanic/Latino as an ethnic category. This table excludes Latinos from the racial categories and assigns them to a separate category. Hispanics/Latinos can be of any race.

The 2010 United States Census reported that El Dorado County had a population of 181,058. The racial makeup of El Dorado County was 156,793 (86.6%) White, 1,409 (0.8%) African American, 2,070 (1.1%) Native American, 6,297 (3.5%) Asian, 294 (0.2%) Pacific Islander, 7,278 (4.0%) from other races, and 6,917 (3.8%) from two or more races.

As of the census^[32] of 2000, there were 156,299 people, 58,939 households, and 43,025 families residing in the county. The population density was 91 inhabitants per square mile (35/km²).

El Dorado is a predominantly Republican county in presidential and congressional elections. However, from 1880 until 1952, the county was a Democratic stronghold, with Theodore Roosevelt and Warren Harding being the only two Republicans to carry the county. Since 1952, however, El Dorado has gone Democratic only three times: in 1960 narrowly for John F. Kennedy, in 1964 in a landslide for Lyndon Johnson, and in 1976 narrowly for Jimmy Carter.

The county is noted as a center of political concern with the United Nations non-binding sustainable development plan Agenda 21, which was on the County Board of Supervisors meeting Agenda on May 15, 2012. Concerns included the threat of U.S. Forest Service road closures and traffic roundabouts.^[35] On February 19, 2013, 14 members of the El Dorado County Grand Jury resigned, forcing Supervising Judge Steven Bailey to dissolve it.^[36]

El Dorado County has a secessionist movement, calling for the county of less than 200,000 residents to become a new state of the union. Wyoming, the least populous current state, has approximately three times the number of residents. Sharon Durst, one of the leaders of the movement, was previously a supporter of the State of Jefferson movement, that advocates for Northern California counties and Southern Oregon counties to form a new state. El Dorado County's seat, Placerville, California, is located 45 miles from Sacramento, the state's capital. The leadership of the movement acknowledges that it is unlikely that the California legislature would approve their separation from the state, as required by the United States Constitution. They promote an unproven theory that the county "is technically not a legitimate piece of California and is instead 'other property' of Congress".^[37]

El Dorado County is split between two Congressional districts, with the western third of the County in the 5th Congressional District, represented by Tom McClintock, and the eastern two-thirds in the 3rd Congressional District, represented by Kevin Kiley. In the State Assembly, the county is split between the 5th Assembly District, represented by Republican Joe Patterson and the 6th Assembly District, represented by Democrat Kevin McCarty.^[38] In the State Senate, it is in the 1st Senate District, represented by Republican Brian Dahle.^[39]

Portions of El Dorado County are known to contain natural asbestos formations near the surface.^[44] The USGS studied amphiboles in rock and soil in the area in response to an EPA sampling study and subsequent criticism of the EPA study. The study found that many amphibole particles in the area meet the counting rule criteria used by the EPA for chemical and morphological limits, but do not meet morphological requirements for commercial-grade-asbestos. The executive summary pointed out that even particles that do not meet requirements for commercial-grade-asbestos may be a health threat and suggested a collaborative research effort to assess health risks associated with naturally occurring asbestos.^[45]

In 2003 after construction of the Oak Ridge High School (El Dorado Hills) soccer field, the federal Agency for Toxic Substances and Disease Registry found that some student athletes, coaches and school workers had received substantial exposures. The inside of the school needed to be cleaned of dust.^[44]
