San Diego-Chula Vista-Carlsbad, CA MSA

San Diego County (), officially the County of San Diego, is a county in the southwestern corner of the U.S. state of California. As of the 2020 census, the population was 3,298,634, making it California's second-most populous county and the fifth-most populous in the United States. Its county seat is San Diego, the second-most populous city in California and the eighth-most populous city in the United States. It is the southwesternmost county in the 48 contiguous United States, and is a border county. It is also home to 18 Native American tribal reservations, the most of any county in the United States.

San Diego County comprises the San Diego-Chula Vista-Carlsbad, CA Metropolitan Statistical Area, which is the 17th most populous metropolitan statistical area and the 18th most populous primary statistical area of the United States as of July 1, 2012. San Diego County is also part of the San Diego–Tijuana transborder metropolitan area, the largest metropolitan area shared between the United States and Mexico.

San Diego County has more than of coastline. This forms the most densely populated region of the county, which has a mild Mediterranean to semiarid climate and extensive chaparral vegetation, similar to the rest of the western portion of Southern California. Precipitation and temperature extremes increase to the east, with mountains that receive frost and snow in the winter. These lushly forested mountains receive more rainfall than the average in Southern California, while the desert region of the county lies in a rain shadow to the east, which extends into the Desert Southwest region of North America.

There are 16 military installations, of the U.S. Navy, U.S. Marine Corps, and the U.S. Coast Guard in San Diego County. These include Naval Base San Diego, Marine Corps Base Camp Pendleton, Marine Corps Air Station Miramar, Naval Air Station North Island, and Coast Guard Air Station San Diego.

From north to south, San Diego County extends from the southern borders of Orange and Riverside Counties to the Mexico-U.S. border and the Baja California municipalities of Tijuana and Tecate. From west to east, San Diego County stretches from the Pacific Ocean to its boundary with Imperial County, which separated from it in 1907. Since 2010, statewide droughts in California have further strained San Diego County's water security.

History

The area which is now San Diego County has been inhabited for more than 12,000 years by Kumeyaay (also called Diegueno and Ipai/Tipai), Payómkawichum (Luiseño), Kuupangaxwichem (Cupeño), ʔívil̃uqaletem (Cahuilla), and the Acjachemen (Juaneño) Indians and their local predecessors.

In 1542, the explorer Juan Rodríguez Cabrillo, who may have been born in Portugal but sailed under the flag of Castile, claimed San Diego Bay for the Spanish Empire, and he named the site San Miguel. In November 1602, Sebastián Vizcaíno surveyed the harbor and what are now Mission Bay and Point Loma and named the area for Saint Didacus, a Spaniard more commonly known as San Diego. European settlement in what is now San Diego County began with the founding of the San Diego Presidio and Mission San Diego de Alcalá by Spanish soldiers and clerics in 1769. This county was part of Alta California under the Viceroyalty of New Spain until the Mexican declaration of independence. From 1821 through 1848 this area was part of Mexico.

San Diego County became part of the United States as a result of the Treaty of Guadalupe Hidalgo in 1848, ending the Mexican–American War. This treaty designated the new border as terminating at a point on the Pacific Ocean coast which would result in the border passing one Spanish league south of the southernmost portion of San Diego Bay, thus ensuring that the United States received all of this natural harbor.

San Diego County was one of the original counties of California, created at the time of California statehood in 1850.

At the time of its establishment in 1850, San Diego County was relatively large, and included all of southernmost California south and east of Los Angeles County. It included areas of what are now Inyo and San Bernardino Counties, as well as all of what are now Riverside and Imperial Counties.

During the later part of the 19th century, there were numerous changes in the boundaries of San Diego County, when various areas were separated to make up the counties mentioned above. The most recent changes were the establishments of Riverside County in 1893 and Imperial County in 1907. Imperial County was also the last county to be established in California, and after this division, San Diego no longer extended from the Pacific Ocean to the Colorado River, and it no longer covered the entire border between California and Mexico.

Geography

According to the U.S. Census Bureau, the county has an area of , of which is land and (7.0%) is water. The county is larger in area than the combined states of Rhode Island and Delaware.

San Diego County has a varied topography. On its western side is more than of coastline. Most of San Diego between the coast and the Laguna Mountains consists of hills, mesas, and small canyons. Snow-capped (in winter) mountains rise to the east, with the Sonoran Desert farther to the east. Cleveland National Forest is spread across the central portion of the county, while the Anza-Borrego Desert State Park occupies most of the northeast.

Although the county's western third is primarily urban, the mountains and deserts in the eastern two-thirds are primarily undeveloped backcountry. Most of these backcountry areas are home to a native plant community known as chaparral. San Diego County contains more than of chaparral, twice as much as any other California county.

North San Diego County is known as North County; the exact geographic definitions of "North County" vary, but it includes the northern suburbs and sometimes certain northern neighborhoods of the city of San Diego.

The eastern suburbs are collectively known as East County, though most still lie in the western third of the county. The southern suburbs and southern detached portion of the city of San Diego, extending to the Mexican border, are collectively referred to as South Bay.

Periodically the area has been subject to wildfires that force thousands to evacuate. The most recent are the December 2017 Lilac Fire and the May 2014 San Diego County wildfires; before them was the Witch Creek Fire in 2007 and the Cedar Fire in 2003. California defines a fire season in which fires are most likely to occur, usually between late July and late October (which are the driest months of the area). Signs posted in numerous spots of the county provide information on the level of threats from fires based on weather conditions.

Climate

Under the Köppen climate classification system, the urban and suburban San Diego area straddles areas of Mediterranean climate (CSa) to the north and semi-arid climate (BSh) to the south and east. As a result, it is often described as "arid Mediterranean" and "semi-arid steppe." Farther east, arid desert conditions prevail. Western San Diego's climate is characterized by warm, dry summers and mild winters with most of the annual precipitation falling between November and March. The city has mild, mostly dry weather, with an average of 201 days above and low rainfall ( annually). Summer temperatures are generally warm, with average highs of and lows of . Temperatures exceed only four days a year. Most rainfall occurs from November to April. Winter temperatures are mild, with average high temperatures of and lows of .

The climate in the San Diego area, like much of California, often varies significantly over short geographical distances resulting in microclimates. In San Diego's case this is mainly due to the city's topography (the Bay, and the numerous hills, mountains, and canyons). Frequently, particularly during the "May gray/ June gloom" period, a thick marine layer will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately inland. This happens every year in May and June. Even in the absence of June gloom, inland areas tend to experience much more significant temperature variations than coastal areas, where the ocean serves as a moderating influence. Thus, for example, downtown San Diego averages January lows of and August highs of . The city of El Cajon, just northeast of downtown San Diego, averages January lows of and August highs of . Julian, in the mountains, has an average January low of and August high of . Borrego Springs, in the Colorado Desert, has an average January low of and August high of .

Rainfall along the coast averages about of precipitation annually, which occurs mainly during the cooler months of December through April. Though there are few wet days per month during the rainy period, rainfall can be heavy when it does occur. However, the rainfall is greater in the higher elevations of San Diego. Some of the higher areas of San Diego, such as Palomar Mountain and the Laguna Mountains, receive of rain per year, supporting lush forests similar to the Sierra Nevada and California Coast Range. The Colorado Desert portion of the county lies to the east of the mountains, which receives the least amount of precipitation; Borrego Springs, the largest population center in the desert, averages only , with a high evaporation rate.

Government

The Government of San Diego County, California, Government of San Diego County is defined and authorized under the California Constitution, California law, and the Charter of the County of San Diego. Much of the Government of California is in practice the responsibility of county governments such as the Government of San Diego County. The County government provides countywide services such as elections and voter registration, law enforcement, jails, vital records, property records, tax collection, public health, and social services. In addition the County serves as the local government for all unincorporated areas. Some chartered cities such as San Diego and Chula Vista, California, Chula Vista provide municipal services such as police, public safety, libraries, parks and recreation, and zoning. Other cities such as Del Mar, California, Del Mar and Vista, California, Vista arrange to have the County provide some or all of these services on a contract basis.

The county government is composed of the elected five-member San Diego County Board of Supervisors, Board of Supervisors, several other elected offices and officers

and numerous county departments and entities under the supervision of the Chief Administrative Officer such as the San Diego County, California Probation, Probation Department. In addition, several entities of the government of California have jurisdiction conterminous with San Diego County, such as the Superior Court of San Diego County, San Diego Superior Court.

Under its foundational Charter, the five-member elected San Diego County Board of Supervisors is the county legislature. The board operates in a legislative, executive, and Quasi-judicial body, 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.

As of January 2021, the members of the San Diego County Board of Supervisors are:

For several decades, ending in 2013, all five supervisors were Republican Party (United States), Republican, White American, white, graduates of San Diego State University, and had been in office since 1995 or earlier. The Board was criticized for this homogeneity, which was made possible because supervisors draw their own district lines and are not subject to term limits. (In 2010 voters put term limits in place, but they only apply going forward, so that each incumbent supervisor can serve an additional two terms before being termed out.) That pattern was broken in 2013 when Slater-Price retired; she was replaced by Democratic Party (United States), Democrat Dave Roberts, who won election to the seat in November 2012 and was inaugurated in January 2013.

The San Diego County Code is the codification (law), codified law of San Diego County in the form of local ordinance, ordinances passed by the Board of Supervisors. The Administrative Code establishes the powers and duties of all officers and the procedures and rules of operation of all departments.

The county motto is "The noblest motive is the public good." County government offices are housed in the historic San Diego County Administration Center, County Administration Center Building, constructed in 1935–1938 with funding from the Works Progress Administration.

Politics

Voting

San Diego County had historically been a Republican Party (United States), Republican stronghold. The Republican presidential nominee carried the county in every presidential election from 1948 through 2004, except in 1992 when Bill Clinton won a plurality. In 2008, Barack Obama became the first Democratic Party (United States), Democratic presidential candidate to win a majority of votes in San Diego County since World War II; he won a majority of county votes again in 2012. In 2020, the county voted in favor of the Democratic presidential nominee Joe Biden by 22.8%, the largest margin for a Democrat since United States presidential election in California, 1936, 1936.

The city of San Diego itself is more Democratic than the county's average and has voted for Democrats in each presidential election since 1992. Various cities within the county are swing areas that have split their votes in elections since 2000. Republican strength is concentrated in North County, East County and the eastern backlands. Coronado has also traditionally been a Republican stronghold.

One unique feature of the political scene is the use of Golden Hall (sports venue), Golden Hall, a convention facility next to San Diego's City Hall, as "Election Central." The County Registrar of Voters rents the hall to distribute election results. Supporters and political observers gather to watch the results come in; supporters of the various candidates parade around the hall, carrying signs and chanting; candidates give their victory and concession speeches and host parties for campaign volunteers and donors at the site; and television stations broadcast live from the floor of the convention center. The atmosphere at Election Central on the evening of election day has been compared to the voting portion of a political party national convention.

On November 4, 2008, San Diego County voted 53.71% for Proposition 8 which amended the California Constitution to ban same-sex marriages, thus restoring California Proposition 22 (2000), Proposition 22 which was overturned by a ruling from the California Supreme Court. However the city of San Diego, along with the North County coastal cities of Del Mar, Encinitas, and Solana Beach, voted against Proposition 8. La Mesa was a virtual tie for Prop 8 support, while Carlsbad supported the referendum by only a 2% margin.
