The Cucamonga Valley is a region of southwestern San Bernardino County and northwestern Riverside County, in southern California. [1] It is located below the San Gabriel Mountains in the Inland Empire region.



It is a region of the eastern Pomona Valley and western San Bernardino Valley. It is located between Los Angeles and San Bernardino.

The Cucamonga Valley AVA, a designated American Viticultural Area, is in the valley region. It was a major site of wine production in the late 19th through mid−20th centuries, before regional urban expansion with land development and suburbanization spread into the area.



The demographics of the Cucamonga Valley have been shifting in recent years. The population of European Americans, who once constituted a large majority, is on the decline while the population of Latinos and African Americans is growing. Unlike most of Southern California, there is not a particularly strong representation of Asian Americans in the Cucamonga Valley, although it is steadily increasing. The city of Rancho Cucamonga has the highest population of Asian Americans in the Cucamonga Valley, at 9.0% of the population.[ citation needed ]

Many of the existing freeways in Southern California's Inland Empire were completed in the late 1970s. The only exception is the segment of the Foothill Freeway, State Route 210 between San Dimas and San Bernardino, completed in July 2007. In general, most of the higher paying jobs are located in Los Angeles and Orange County. Thus, workers must commute daily up to two hours in each direction on the existing network. As the population increases, traffic congestion is projected to increase as well.
