Coachella is a city in Riverside County, California; it is the easternmost city in the region collectively known as the Coachella Valley (or the Palm Springs area). It is located 28 miles (45 km) east of Palm Springs, 72 miles (116 km) east of Riverside, and 130 miles (210 km) east of Los Angeles. Known as the "City of Eternal Sunshine", Coachella is largely a rural, agricultural, family-oriented community in the desert and one of the state's fastest growing cities in the late 20th century. When it first incorporated back in 1946, it had 1,000 residents, but the population was 22,724 at the 2000 census. The eastern half of the Coachella valley is below sea level, and the area's average elevation is 68 feet (35 m) below sea level. The Salton Sea, a saltwater lake located about 10 miles (16 km) South of Coachella, lies 227 feet (69 m) below sea level. The city also lends its name to the Coachella grapefruit; the town's stretch of State Route 111 is named Grapefruit Boulevard in its honor. Harrison Street or State Route 86 is declared historic U.S. Route 99, the major throughfare that connects with Interstate 10 a few miles north of town.
