San Diego(⫽ˌsændiˈeɪɡoʊ⫽SANdee-AY-goh,Spanish:[sanˈdjeɣo]) is a city on thePacific Oceancoast inSouthern Californialocated immediately adjacent to theMexico–United States border.With a population of over 1.3 million residents, the city is theeighth-most populous in the United Statesand thesecond-most populousin thestateofCaliforniaafterLos Angeles.The city is thecounty seatofSan Diego County,which had a population of nearly 3.3 million people as of 2021.San Diego is known for its mild year-roundMediterranean climate,extensivebeachesandparks,its long association with theUnited States Navy,and its recent emergence as ahealthcareandbiotechnologydevelopment center.

Historically home to theKumeyaayNative Americans, San Diego has been referred to as theBirthplace of California,as it was the first site visited and settled by Europeans on what is now theWest Coast of the United States.Upon landing inSan Diego Bayin 1542,Juan Rodríguez Cabrilloclaimed the area forSpain,forming the basis for the settlement ofAlta California200 years later. ThePresidioandMission San Diego de Alcalá,founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly declaredMexican Empire,which reformed as theFirst Mexican Republictwo years later. California was conquered by the U.S. in 1848 following theMexican–American Warand wasadmitted to the union as a state in 1850.

San Diego's main economic enginesare military and defense-related activities, tourism, international trade, research, and manufacturing. The city is home to several universities, includingUC San Diego,San Diego State University,and theUniversity of San Diego.San Diego is the economic center of theSan Diego–Tijuanaconurbation,the second-most populoustransborder metropolitan areain theWestern Hemisphere,home to an estimated 5 million people as of 2022.The primary border crossing between San Diego andTijuana,theSan Ysidro Port of Entry,is the busiest international land border crossing in the world outside of Asia (fourth-busiestoverall). The city's airport,San Diego International Airport,is the busiest single-runwayairport in the United States.

Name

Etymology

San Diego's name can be traced back to the 16th century when Spanish explorerSebastián Vizcaínobestowed it upon the area in 1602. He named the bay and the surrounding area "San Diego de Alcalá" in honor ofSaint Didacus of Alcalá.

Kumeyaay Toponymy

Prior to the Spanish establishment of San Diego, theKumeyaaytown was calledKosa'aay,meaning "drying out place" in theKumeyaay language.After the establishment of San Diego, the Kumeyaay called town and cityTepacul Watai,meaning "Stacked Big".Luiseñospeakers in theNorth County regioncalled itPushuyi.

History

For a chronological guide, seeTimeline of San Diego.

Pre-colonial period

TheKumeyaay,referred to by the Spanish asDiegueños,have inhabited the area for thousands of years.

What has been referred to as theSan Dieguito complexwas established in the area at least 9,000 years ago.TheKumeyaaymay have culturally evolved from this complex or migrated into the area around 1000 C.E.ArchaeologistMalcolm Rogershypothesized that the early cultures of San Diego were separate from theKumeyaay,yet this claim is disputed, with others noting that it does not account forcultural evolution.Rogers later reevaluated his claims, yet they were influential in shaping historical tellings of early San Diego history.

The Kumeyaay established villages scattered across the region, including the village ofKosa'aaywhich was the Kumeyaay village that the future settlement of San Diego would stem from in today'sOld Town.The village of Kosa'aay was made up of thirty to forty families living in pyramid-shaped housing structures and was supported by a freshwater spring from the hillsides.

Spanish period

Portuguese explorerJuan Rodríguez Cabrillolanding inSan Diego Bayin 1542, claiming California for theSpanish Empire

The first European to visit the region was explorerJuan Rodríguez Cabrillo,sailing under the flag ofCastilebut possiblyborn in Portugal.Sailing his flagshipSan SalvadorfromNavidad,New Spain, Cabrillo claimed the bay for theSpanish Empirein 1542, and named the site "San Miguel".In November 1602,Sebastián Vizcaínowas sent to map the California coast. Arriving on his flagshipSan Diego,Vizcaíno surveyed the harbor and what are nowMission BayandPoint Lomaand named the area for the CatholicSaint Didacus,aSpaniardmore commonly known asSan Diego de Alcalá.On November 12, 1602, the first Christian religious service of record inAlta Californiawas conducted by Friar Antonio de la Ascensión, a member of Vizcaíno's expedition, to celebrate the feast day of San Diego.

The permanentEuropean colonizationof both California and San Diego began in 1769 with the arrival of four contingents of Spaniards from New Spain and theBaja Californiapeninsula. Two seaborne parties reached San Diego Bay: theSan Carlos,under Vicente Vila and including as notable members the engineer and cartographerMiguel Costansóand the soldier and future governorPedro Fages,and theSan Antonio,underJuan Pérez.An initial overland expedition to San Diego from the south was led by the soldierFernando Riveraand included theFranciscanmissionary, explorer, and chroniclerJuan Crespí,followed by a second party led by the designated governorGaspar de Portolàand including the mission president (and now saint)Junípero Serra.

Mission San Diego de Alcaláwas founded in 1769 bySaint Junípero Serra,making it the oldest of theSpanish missions in California.

In May 1769, Portolà established the FortPresidio of San Diegoon a hill near theSan Diego Riverabove the Kumeyaay village of Cosoy,which would later become incorporated into the Spanish settlement,making it the first settlement by Europeans in what is now the state of California. In July of the same year,Mission San Diego de Alcaláwas founded by Franciscan friars under Serra.The mission became a site for a Kumeyaay revolt in 1775, which forced the mission to relocate six miles (10 km) up the San Diego River.By 1797, the mission boasted the largest native population in Alta California, with over 1,400 neophytes living in and around the mission proper.Mission San Diego was the southern anchor inAlta Californiaof the historic mission trailEl Camino Real.Both the Presidio and the Mission areNational Historic Landmarks.

Mexican period

José María Estudilloserved as commandant of thePresidio of San Diegoand founded theEstudillo family,a powerful clan ofCalifornios.

In 1821,Mexicowon its independence from Spain,and San Diego became part of the Mexican territory ofAlta California.In 1822, Mexico began its attempt to extend its authority over the coastal territory of Alta California. The fort on Presidio Hill was gradually abandoned, while the town of San Diego grew up on the level land below Presidio Hill. The Mission wassecularized by the Mexican government in 1834,and most of the Mission lands were granted to former soldiers. The 432residentsof the town petitioned the governor to form apueblo,andJuan María Osunawas elected the firstalcalde( "municipal magistrate" ), defeatingPío Picoin the vote. Beyond the town, Mexicanland grantsexpanded the number ofCalifornia ranchosthat modestly added to the local economy. (See,List of pre-statehood mayors of San Diego.)

However, San Diego had been losing population throughout the 1830s, due to increasing tension between the settlers and the indigenousKumeyaayand in 1838 the town lost its pueblo status because its size dropped to an estimated 100 to 150 residents.Theranchosin the San Diego region would face Kumeyaay raids in the late 1830s and the town itself would face raids in the 1840s.

Americans gained an increased awareness of California, and its commercial possibilities, from the writings of two countrymen involved in the often officially forbidden, to foreigners, but economically significant hide and tallow trade, where San Diego was a major port and the only one with an adequate harbor:William Shaler's "Journal of a Voyage Between China and the North-Western Coast of America, Made in 1804" andRichard Henry Dana's more substantial and convincing account, of his 1834–36 voyage, the classicTwo Years Before the Mast.

Casa de Estudillo,built 1827, is one of San Diego's oldest buildings and served as inspiration forHelen Hunt Jackson's 1884 novelRamona.

In 1846, the United States went to war against Mexico and sent a naval and landexpedition to conquer Alta California.At first, they had an easy time of it, capturing the major ports including San Diego, but the Californios in southern Alta California struck back. Following the successful revolt inLos Angeles,the American garrison at San Diego was driven out without firing a shot in early October 1846. Mexican partisans held San Diego for three weeks until October 24, 1846, when the Americans recaptured it. For the next several months the Americans were blockaded inside the pueblo. Skirmishes occurred daily and snipers shot into the town every night. The Californios drove cattle away from the pueblo hoping to starve the Americans and their Californio supporters out. On December 1, the American garrison learned that the dragoons of GeneralStephen W. Kearneywere atWarner's Ranch.CommodoreRobert F. Stocktonsent a mounted force of fifty under CaptainArchibald Gillespieto march north to meet him. Their joint command of 150 men, returning to San Diego, encountered about 93 Californios underAndrés Pico.

The 1846Battle of San Pasqualwas a decisive battle between American andCalifornioforces.

In the ensuingBattle of San Pasqual,fought in theSan Pasqual Valleywhich is now part of the city of San Diego, the Americans suffered their worst losses in the campaign. Subsequently, a column led by Lieutenant Gray arrived from San Diego, rescuing Kearny's battered and blockaded command.Stockton and Kearny went on to recover Los Angeles and force the capitulation of Alta California with the "Treaty of Cahuenga"on January 13, 1847. As a result of theMexican–American Warof 1846–48, the territory of Alta California, including San Diego, was ceded to the United States by Mexico, under the terms of theTreaty of Guadalupe Hidalgoin 1848. The Mexican negotiators of that treaty tried to retain San Diego as part of Mexico, but the Americans insisted that San Diego was "for every commercial purpose of nearly equal importance to us with that of San Francisco", and the Mexican–American border was eventually established to be one league south of the southernmost point ofSan Diego Bay,so as to include the entire bay within the United States.

American period

The state of California was admitted to the United States in 1850. That same year San Diego was designated the seat of the newly established County of San Diego and was incorporated as a city.Joshua H. Bean,the last alcalde of San Diego, was elected the first mayor. Two years later the city was bankrupt;the California legislature revoked the city's charter and placed it under control of a board of trustees, where it remained until 1889. A city charter was reestablished in 1889, and today's city charter was adopted in 1931.

The original town of San Diego was located at the foot of Presidio Hill, in the area which is nowOld Town San Diego State Historic Park.The location was not ideal, being several miles away from navigable water at its port atLa Playa.In 1850,William Heath Davispromoted a new development by the bay shore called "New San Diego", several miles south of the original settlement; however, for several decades the new development consisted only of a pier, a few houses and anArmy depotfor the support ofFort Yuma.After 1854, the fort became supplied by sea and bysteamboats on the Colorado Riverand the depot fell into disuse. From 1857 to 1860, San Diego became the western terminus of theSan Antonio-San Diego Mail Line,the earliest overlandstagecoachand mail operation from theEastern United Statesto California, coming fromTexasthroughNew Mexico Territoryin less than 30 days.

Horton PlazahonorsAlonzo Horton,who helped developDowntown.

In the late 1860s,Alonzo Hortonpromoted a move to the bayside area, which he called "New Town" and which becameDowntown San Diego.Horton promoted the area heavily, and people and businesses began to relocate to New Town because its location onSan Diego Baywas convenient to shipping. New Town soon eclipsed the original settlement, known to this day asOld Town,and became the economic and governmental heart of the city.Still, San Diego remained a relative backwater town until the arrival of a railroad connection in 1878. In 1884–1886,John J. Montgomerymade the first controlled flights by an American in a heavier-than-air unpowered glider just south of San Diego at Otay Mesa, helping to pioneer a new science of aerodynamics.

In 1912, San Diego was the site of afree speech fightbetween theIndustrial Workers of the Worldand the city government who passed an ordinance forbidding thefreedom of speechalong an area of "Soapbox Row" that led to civil disobedience,vigilantism,police violence,the abduction ofEmma Goldman's husbandBen Reitmanandmultiple riots.San Diego's proximity to Tijuana during theMexican Revolutionmade this one of the most significantfree speech fightsduring theWobblyera.

In 1916, the neighborhood ofStingaree,the original home of San Diego's firstChinatownand "Soapbox Row", was demolished by anti-vicecampaigners to make way for theGaslamp Quarter.

Balboa Parkwas built for thePanama-California Exposition of 1915.

In the early part of the 20th century, San Diego hosted theWorld's Fairtwice: thePanama-California Exposition (1915)and theCalifornia Pacific International Expositionin 1935. Both expositions were held inBalboa Park,and many of the Spanish/Baroque-style buildings that were built for those expositions remain to this day as central features of the park. The buildings were intended to be temporary structures, but most remained in continuous use until they progressively fell into disrepair. Most were eventually rebuilt, using castings of the original façades to retain the architectural style.The menagerie of exotic animals featured at the 1915 exposition provided the basis for theSan Diego Zoo.During the 1950s there was a citywide festival calledFiesta del Pacificohighlighting the area's Spanish and Mexican past.In the 2010s there was a proposal for a large-scale celebration of the 100th anniversary of Balboa Park, but the plans were abandoned when the organization tasked with putting on the celebration went out of business.

The southern portion of thePoint Lomapeninsula was set aside for military purposes as early as 1852. Over the next several decades theArmyset up a series of coastal artillery batteries and named the areaFort Rosecrans.Significant U.S. Navy presence began in 1901 with the establishment of the Navy Coaling Station in Point Loma, and expanded greatly during the 1920s.By 1930, the city was host toNaval Base San Diego,Naval Training Center San Diego,San Diego Naval Hospital,Camp Matthews,andCamp Kearny(nowMarine Corps Air Station Miramar). The city was also an early center for aviation: as early as World War I, San Diego was proclaiming itself "The Air Capital of the West".The city was home to important airplane developers and manufacturers like Ryan Airlines (laterRyan Aeronautical), founded in 1925, andConsolidated Aircraft(laterConvair), founded in 1923.Charles A. Lindbergh's planeThe Spirit of St. Louiswas built in San Diego in 1927 by Ryan Airlines.

Downtown San Diego,c. 1903

DuringWorld War II,San Diego became a major hub of military and defense activity, due to the presence of so many military installations and defense manufacturers. The city's population grew rapidly during and after World War II, more than doubling between 1930 (147,995) and 1950 (333,865).During the final months of the war, the Japanese had a plan to target multiple U.S. cities forbiological attack,starting with San Diego. The plan was called "Operation Cherry Blossoms at Night"and called forkamikazeplanes filled with fleas infected with plague (Yersinia pestis) to crash into civilian population centers in the city, hoping to spread plague in the city and effectively kill tens of thousands of civilians. The plan was scheduled to launch on September 22, 1945, but was not carried out becauseJapan surrenderedfive weeks earlier.

After World War II, the military continued to play a major role in the local economy, but post-Cold Warcutbacks took a heavy toll on the local defense and aerospace industries. The resulting downturn led San Diego leaders to seek to diversify the city's economy by focusing on research and science, as well as tourism.

Starting in the 1980s, many areas of Downtown, such as theMarina District,underwentredevelopment.

From the start of the 20th century through the 1970s, the Americantunafishing fleet and tuna canning industry were based in San Diego, "the tuna capital of the world".San Diego's first tuna cannery was founded in 1911, and by the mid-1930s the canneries employed more than 1,000 people. A large fishing fleet supported the canneries, mostly staffed by immigrant fishermen fromJapan,and later from thePortugueseAzoresandItalywhose influence is still felt in neighborhoods likeLittle ItalyandPoint Loma.Due to rising costs and foreign competition, the last of the canneries closed in the early 1980s.

Downtown San Diego was in decline in the 1960s and 1970s, but experienced some urban renewal since the early 1980s, including the opening ofHorton Plaza,the revival of theGaslamp Quarter,and the construction of theSan Diego Convention Center;Petco Parkopened in 2004.Outside of downtown, San Diego annexed large swaths of land and for suburban expansion to the north and control of theSan Ysidro Port of Entry.

As theCold Warended, the military shrank and so did defense spending. San Diego has since become a center of the emerging biotech industry and is home to telecommunications giantQualcomm.San Diego had also grown in the tourism industry with the popularity of attractions such as theSan Diego Zoo,SeaWorld San Diego,andLegoland CaliforniainCarlsbad.

According to SDSU professor emeritus Monte Marshall,San Diego Bayis "the surface expression of a north-south-trending, nestedgraben".TheRose CanyonandPoint Lomafault zonesare part of theSan Andreas Faultsystem. About 40 miles (64 km) east of the bay are theLaguna Mountainsin thePeninsular Ranges,which are part of thebackbone of the American continents.

The city lies on approximately 200 deep canyons and hills separating itsmesas,creating small pockets of natural open space scattered throughout the city and giving it a hilly geography.Traditionally, San Diegans have built their homes and businesses on the mesas, while leaving the urban canyons relatively wild.Thus, the canyons give parts of the city a segmented feel, creating gaps between otherwise proximate neighborhoods and contributing to a low-density, car-centered environment. TheSan Diego Riverruns through the middle of San Diego from east to west, creating a river valley that serves to divide the city into northern and southern segments. During the historic period and presumably earlier as well, the river has shifted its flow back and forth between San Diego Bay and Mission Bay, and itsfresh waterwas the focus of the earliest Spanish explorers.Miguel Costansó,a cartographer, wrote in 1769, "When asked by signs where the watering-place was, the Indians pointed to a grove which could be seen at a considerable distance to the northeast, giving to understand that a river or creek flowed through it, and that they would lead our men to it if they would follow."That river was the San Diego River.Several reservoirs andMission Trails Regional Parkalso lie between and separate developed areas of the city.

Torrey Pines State Natural Reserve

Notable peaks within the city limits includeCowles Mountain,the highest point in the city at 1,591 feet (485 m);Black Mountainat 1,558 feet (475 m); andMount Soledadat 824 feet (251 m). TheCuyamaca Mountainsand Laguna Mountains rise to the east of the city, and beyond the mountains are desert areas. TheCleveland National Forestis a half-hour drive from downtown San Diego. Numerous farms are found in the valleys northeast and southeast of the city.

Under theKöppen–Geiger climate classification system,the San Diego area has been variously categorized as having either ahot semi-arid climate(BShin the original classificationandBSknin modified Köppen classification with the n denoting summer fog)or ahot-summer Mediterranean climate(Csa).San Diego's climate is characterized by warm, dry summers and mild winters, with most of the annual precipitation falling between December and March. The city has a mild climate year-round,with an average of 201 days above 70 °F (21 °C) and low rainfall (9–13 inches [230–330 mm] annually).

The climate in San Diego, like most of Southern California, often varies significantly over short geographical distances, resulting inmicroclimates.In San Diego, this is mostly because of 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"cloud cover keeps the air cool and damp within a few miles of the coast, but yields to bright cloudless sunshine approximately 5–10 miles (8–16 km) inland.Sometimes the June gloom lasts into July, causing cloudy skies over most of San Diego for the entire day.Even in the absence of June gloom, inland areas 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 50 °F (10 °C) and August highs of 78 °F (26 °C). The city ofEl Cajon,just 12 miles (19 km) inland from downtown San Diego, averages January lows of 42 °F (6 °C) and August highs of 88 °F (31 °C).

The average surface temperature of the water at Scripps Pier in theCalifornia Currenthas increased by almost 3 °F (1.7 °C) since 1950, according to scientists atScripps Institution of Oceanography.Additionally, the mean minimum is now above 40 °F (4 °C), putting San Diego inhardiness zone11, with the last freeze having occurred many decades ago.

Annual rainfall along the coast averages 10.65 inches (271 mm) and the median is 9.6 inches (240 mm).The months of December through March supply most of the rain, with February the only month averaging 2 inches (51 mm) or more. The months of May through September tend to be almost completely dry. Although there are few wet days per month during the rainy period, rainfall can be heavy when it does fall. Rainfall is usually greater in the higher elevations of San Diego; some of the higher areas can receive 11–15 inches (280–380 mm) per year. Variability from year to year can be dramatic: in the wettest years of 1883/1884 and 1940/1941, more than 24 inches (610 mm) fell, whilst in the driest years there was as little as 3.2 inches (80 mm). The wettest month on record is December 1921 with 9.21 inches (234 mm).

Snow in the city is rare, having been observed only six times in the century and a half that records have been kept. In 1949 and 1967, snow remained on the ground for a few hours in higher locations likePoint LomaandLa Jolla.The other three occasions, in 1882, 1946, and 1987, involved flurries but no accumulation.On February 21, 2019, snow fell and accumulated in residential areas of the city, but none fell in the downtown area.

Ecology

View ofCoronadofromCabrillo National Monument

Like much ofSouthern California,the majority of San Diego's current area was originally occupied on the west bycoastal sage scruband on the east bychaparral,plant communities made up mostly of drought-resistant shrubs.The steep and varied topography and proximity to the ocean create a number of different habitats within the city limits, includingtidal marshandcanyons.The chaparral and coastal sage scrub habitats in low elevations along the coast are prone towildfire,and the rates of fire increased in the 20th century, due primarily to fires starting near the borders of urban and wild areas.

San Diego's broad city limits encompass a number of large nature preserves, includingTorrey Pines State Reserve,Los Peñasquitos Canyon Preserve,andMission Trails Regional Park.Torrey Pines State Reserve and a coastal strip continuing to the north constitute one of only two locations where the rare species of Torrey Pine,Pinus torreyana,is found. Due to the steep topography that prevents or discourages building, along with some efforts for preservation, there are also a large number of canyons within the city limits that serve as nature preserves, includingSwitzer Canyon,Tecolote Canyon Natural Park,and Marian Bear Memorial Park inSan Clemente Canyon,as well as a number of small parks and preserves.

San Diego County has one of the highest counts of animal and plant species that appear on theendangered listof counties in the United States.Because of its diversity of habitat and its position on thePacific Flyway,San Diego County has recorded 492 different bird species, more than any other region in the country.San Diego always scores high in the number of bird species observed in the annualChristmas Bird Count,sponsored by theAudubon Society,and it is known as one of the "birdiest" areas in the United States.

San Diego and its backcountry suffer from periodic wildfires. In October 2003, San Diego was the site of theCedar Fire,at that time the largest wildfire in California over the past century.The fire burned 280,000 acres (1,100 km²), killed 15 people, and destroyed more than 2,200 homes.In addition to damage caused by the fire, smoke resulted in a significant increase in emergency room visits due to asthma, respiratory problems, eye irritation, and smoke inhalation; the poor air quality caused San Diego County schools to close for a week.Wildfires four years laterdestroyed some areas, particularly withinRancho Bernardo,as well as the nearby communities ofRancho Santa FeandRamona.

Aerial view of central San Diego

San Diego was originally centered on theOld Towndistrict, but by the late 1860s the focus had shifted to the bayfront, in the belief that this new location would increase trade. As the "New Town" – present-day Downtown – waterfront location quickly developed, it eclipsed Old Town as the center of San Diego.

The first skyscraper over 300 feet (91 m) in San Diego was theEl Cortez Hotel,built in 1927; it was the tallest building in the city until 1963.As time went on, multiple buildings claimed the title of San Diego's tallest skyscraper, including the530 B StreetandSymphony Towers.Currently the tallest building in San Diego isOne America Plaza,standing 500 feet (150 m) tall, which was completed in 1991.The downtown skyline contains nosupertallbuildings due to a regulation put in place by theFederal Aviation Administrationin the 1970s, which set a 500 feet (152 m) limit on the height of buildings within a one-mile (1.6 km) radius of theSan Diego International Airport.An iconic description of the skyline includes its skyscrapers being compared to the tools of a toolbox.

There areseveral new high-rises under construction,including two that exceed 400 feet (122 m) in height.

According to data from the Downtown San Diego Partnership, the number of individuals living outside or in vehicles has reached a two-year low, standing at approximately 1,200 as of last month.

On November 28, 2005, U.S. CongressmanRandy "Duke" Cunninghamresigned after being convicted on federalbriberycharges. He had representedCalifornia's 50th congressional district,which includes much of the northern portion of the city of San Diego. In 2006, Cunningham was sentenced to a 100-month prison sentence.He was released in 2013.

In 2005 two city council members,Ralph Inzunzaand Deputy MayorMichael Zucchet– who briefly took over as acting mayor when Murphy resigned – were convicted ofextortion,wire fraud,andconspiracy to commit wire fraudfor taking campaign contributions from astrip clubowner and his associates, allegedly in exchange for trying to repeal the city's "no touch" laws at strip clubs.Both subsequently resigned. Inzunza was sentenced to 21 months in prison.In 2009, a judge acquitted Zucchet on seven out of the nine counts against him, and granted his petition for a new trial on the other two charges;the remaining charges were eventually dropped.

In July 2013, three former supporters of mayorBob Filnerasked him to resign because of allegations of repeatedsexual harassment.Over the ensuing six weeks, 18 women came forward to publicly claim that Filner had sexually harassed them,and multiple individuals and groups called for him to resign.

TheSan Diego Daily Transcriptis a business-oriented online newspaper.

San Diego is also the headquarters of the nationalfar-rightcable TV channelOne America News Network (OANN),which was founded in 2013 and is owned byHerring Networks.The network gained notoriety for being ardent supporters ofDonald Trumpand providing a platform forright-wingconspiracy theories.

San Diego led U.S. local markets with 69.6 percent broadband penetration in 2004 according toNielsen//NetRatings.

San Diego's first television station wasKFMB,which began broadcasting on May 16, 1949.Since theFederal Communications Commission(FCC) licensed seven television stations in Los Angeles, twoVHFchannels were available for San Diego because of its relative proximity to the larger city. In 1952, however, the FCC began licensingUHFchannels, making it possible for cities such as San Diego to acquire more stations. Stations based in Mexico (withITU prefixesof XE and XH) also serve the San Diego market. Television stations today includeXHCPDE11 (Canal Once (Mexico)),XETV6 (Canal 5/Nueve),KFMB8 (CBS,withThe CW/MNTVon DT2),KGTV10 (ABC),XEWT12 (Televisa Regional),KPBS15 (PBS),KBNT-CD17 (Univision),XHTIT-TDT21 (Azteca 7),XHJK-TDT1 (Azteca Uno),XHAS33 (Canal 66),K35DG-D35 (UCSD-TV),KDTF-LD36 (Unimás),KNSD39 (NBC),KUAN-LD48 (Telemundo),KSEX-CD42 (Infomercials),XHBJ-TDT45 (Canal 6 (Mexico)),XHDTV49 (Milenio Televisión),KUSI51 (Independent),XHUAA-TDT19 (Canal de las Estrellas), andKSWB-TV69 (Fox). San Diego has an 80.6 percent cable penetration rate.

Due to the ratio of U.S. and Mexican-licensed stations, San Diego is the largestmedia marketin the United States that is legally unable to support atelevision station duopolybetween two full-power stations underFCCregulations, which disallow duopolies in metropolitan areas with fewer than nine full-power television stations and require that there would be eight unique station owners that remain once a duopoly is formed (there are only seven full-power stations on the California side of the San Diego-Tijuana market).Though theE. W. Scripps Companyowns KGTV and KZSD-LP, they are not considered a duopoly under the FCC's legal definition as common ownership between full-power andlow-powertelevision stations in the same market is permitted regardless of the number of stations licensed to the area. As a whole, the Mexico side of the San Diego-Tijuana market has two duopolies and one triopoly (Entravision Communicationsowns bothXHAS-TVand XHDTV-TV,AztecaownsXHJK-TVandXHTIT-TV,andGrupo TelevisaownsXHUAA-TVandXEWT-TValong with being the license holder for XETV-TV, which was formerly managed by California-based subsidiaryBay City Television).

San Diego's television market is limited to onlySan Diego County.TheImperial Valley,includingEl Centro,is in theYuma, Arizonatelevision market while neighboringOrangeandRiversidecounties are part of the Los Angeles market. (Sometimes, in the past, a missing network affiliate in the Imperial Valley would be available on cable TV from San Diego.) As a result, San Diego is the largest single-county media market in the United States.

The radio stations in San Diego include nationwide broadcasteriHeartMedia;Entercom Communications,Local Media San Diego, and many other smaller stations and networks.

Infrastructure

Transportation

Main articles:Transportation in San DiegoandStreets and highways of San Diego

Santa Fe Depotis served byAmtrak CaliforniaandCoastertrains.

With the automobile being the primary means of transportation for over 80 percent of residents, San Diego is served by a network of freeways and highways. This includesInterstate 5,which runs south toTijuanaand north to Los Angeles;Interstate 8,which runs east toImperial Countyand theArizona Sun Corridor;Interstate 15, which runs northeast through theInland EmpiretoLas VegasandSalt Lake City;andInterstate 805,which splits from I-5 near the Mexican border and rejoins I-5 atSorrento Valley.

Major state highways includeSR 94,which connects downtown with I-805, I-15 andEast County;SR 163,which connects downtown with the northeast part of the city, intersects I-805 and merges with I-15 atMiramar;SR 52,which connects La Jolla withEast CountythroughSanteeandSR 125;SR 56,which connects I-5 with I-15 throughCarmel ValleyandRancho Peñasquitos;SR 75,which spansSan Diego Bayas theSan Diego-Coronado Bridge,and also passes throughSouth San Diegoas Palm Avenue; andSR 905,which connects I-5 and I-805 to theOtay Mesa Port of Entry.

San Diego Trolleyis operated by theS.D. Metropolitan Transit System.

The stretch of SR 163 that passes through Balboa Park is San Diego's oldest freeway, dating back to 1948 when it was part ofUS 80andUS 395.It has been called one of America's most beautiful parkways.

San Diego's roadway system provides an extensive network of cycle routes. Its dry and mild climate makes cycling a convenient year-round option; however, the city's hilly terrain and long average trip distances make cycling less practicable. Older and denser neighborhoods around the downtown tend to be oriented toutility cycling.This is partly because the grid street patterns are now absent in newer developments farther from the urban core, where suburban-style arterial roads are much more common. As a result, the majority of cycling is recreational.

TheCross Border Xpress,also known as thePuerta delas Californias,connects San Diego toTijuana International AirportinBaja California.

San Diego is served by theSan Diego Trolleylight rail system,by theSDMTS bus system,privatejitneysin some neighborhoods,and byCoasterandAmtrak Pacific Surflinercommuter rail; northernSan Diego countyis also served by theSprinterhybrid rail service.The trolley primarily serves downtown and surrounding urban communities,Mission Valley,east county, and coastal south bay. A mid-coast extension of the Trolley operates fromOld TowntoUniversity Cityand theUniversity of California, San Diegoalong the I-5 Freeway since November 2021. The Amtrak and Coaster trains currently run along the coastline and connect San Diego with Los Angeles, Orange County, Riverside, San Bernardino, and Ventura viaMetrolinkand the Pacific Surfliner. There are two Amtrak stations in San Diego, inOld Townandthe Santa Fe Depotdowntown. San Diego transit information about public transportation and commuting is available on the Web and by dialing "511"from any phone in the area.

San Diego International Airport

The city has two major commercial airports within or near its city limits.San Diego International Airport(SAN) is the busiest single-runway airport in the United States.It served over 24 million passengers in 2018 and is dealing with larger numbers every year.It is located on San Diego Bay, three miles (4.8 km) from downtown, and maintains scheduled flights to the rest of the United States (including Hawaii), as well as to Canada, Germany, Mexico, Japan, and the United Kingdom. It is operated by an independent agency, the San Diego Regional Airport Authority.Tijuana International Airporthas a terminal within the city limits in theOtay Mesadistrict connected to the rest of the airport inTijuana,Mexico,via theCross Border Xpresscross-border footbridge. It is the primary airport for flights to the rest of Mexico, and offers connections via Mexico City to the rest of Latin America. In addition, the city has two general-aviation airports,Montgomery Field(MYF) andBrown Field(SDM).

San Diego BayFestival of Sail

Recent regional transportation projects have sought to mitigate congestion, including improvements to local freeways, expansion of San Diego Airport, and doubling the capacity of the cruise ship terminal. Freeway projects included expansion of Interstates 5 and 805 around "The Merge" where these two freeways meet, as well as expansion of Interstate 15 through North County, which includes newhigh-occupancy-vehicle (HOV) "managed lanes".A tollway (the southern portion of SR 125, known as the South Bay Expressway) connects SR 54 and Otay Mesa, near the Mexican border. According to an assessment in 2007, 37 percent of city streets were in acceptable condition. However, the proposed budget fell $84.6 million short of bringing streets up to an acceptable level.Expansion at the port has included a second cruise terminal onBroadway Pier,opened in 2010. Airport projects include the expansion of Terminal Two.

Utilities

Water is supplied to residents by the Water Department of the City of San Diego. The city receives most of its water from theMetropolitan Water District of Southern California,which brings water to the region from the Sacramento and San Joaquin rivers, via the state project and the Colorado River, via the Colorado Aqueduct.

Gas and electric utilities are provided bySan Diego Gas & Electric,a division ofSempra Energy.The company provides energy service to 3.7 million people through 1.5 million electric meters and 900,000 natural gas meters in San Diego and southern Orange counties.

Street lights

Street lights in theGaslamp Quarter

In the mid-20th century the city hadmercury vaporstreet lamps. In 1978, the city decided to replace them with more efficientsodium vaporlamps. This triggered an outcry fromastronomersatPalomar Observatory60 miles (100 km) north of the city, concerned that the new lamps would increaselight pollutionand hinder astronomical observation.The city altered its lighting regulations to limit light pollution within 30 miles (50 km) of Palomar.

In 2011, the city announced plans to upgrade 80% of its street lighting to new energy-efficient lights that useinduction technology,a modified form offluorescent lampproducing a broader spectrum than sodium vapor lamps. The new system is predicted to save $2.2 million per year in energy and maintenance.The city stated the changes would "make our neighborhoods safer."They also increaselight pollution.

In 2014, San Diego announced plans to become the first U.S. city to install cyber-controlled street lighting, using an "intelligent" lighting system to control 3,000LEDstreet lights.
