Alpine, California

Alpine is a census-designated place (CDP) in the Cuyamaca Mountains of San Diego County, California. Alpine had a population of 14,696 at the 2020 census, up from 14,236 at the 2010 census. The town is largely surrounded by the Cleveland National Forest and borders two reservations of the Kumeyaay Nation, Viejas and Sycuan, and the rural unincorporated areas around the city of El Cajon.

History
Before its modern settlement, the area was part of the home of the Kumeyaay Indians, whose ancestors had lived here for possibly as long as 12,000 years.

The community's name was suggested by a resident in the 1880s who said that the environment reminded her of her native country of Switzerland.

The small commercial district along Alpine Boulevard has seen some suburban development in recent decades, and it is surrounded by large stretches of less densely populated rural areas that began in the late 19th and early 20th centuries. Horse ranches and small farms are still common, along with open chaparral hillsides and riparian canyons.

In 2003, the Cedar Fire ravaged the Alpine area.

Geography
Alpine sits on both sides of Interstate 8 at the eastern extent of the California coastal region and the western extent of the Peninsular Ranges, about 30 mi east of downtown San Diego, at an elevation of about 2000 ft.
