Farmland Mapping and Monitoring Program
1984 to 2008 TIME SERIES
Chino, San Bernardino County

Land use change in the Chino area, 1984-2008. 

In this Image

Changes in this area are predominantly conversions from Prime Farmland (dark green), grasslands/grazing land (brown), and 'Other Land' (grey) to urban (red).  Dairy facilities make up the majority of the Other Land in the area.  Information on these changes was gathered from air photos, local comments, and field reconnaissance. Area shown is approximately 13 miles east-west and 8 miles north-south.

The Inland Empire counties of Riverside and San Bernardino have been among the top urbanizing counties since FMMP began mapping in 1984.  San Bernardino County has averaged over 4,400 new urban acres per year during the 24 year period.  Within the image area, more than 12,500 acres were removed from agricultural uses, and urban land increased by more than 17,000 acres during this timeframe.

A brief history of Chino

Chino is located east of Los Angeles, in the San Gabriel Valley.  It’s agricultural history dates back to the Spanish land grant forming Rancho Santa Ana del Chino. The prime soils in the valley supported orchard and row crops, and it became the number one dairy area in the United States. The city’s motto, “Where Everything Grows” referred to this agricultural beginning.  The city incorporated in 1910.  Adjacent Chino Hills, incorporated in 1991, occupies the western portion of the image.

Starting in the 1970's, its location on Route 60 made Chino one of the first places to feel the impact of the outward migration of families and businesses from Southern California’s coastal counties. The population of Chino increased by more than 70% between 1984 and 2008, while Chino Hills evolved from a small unincorporated area to a population of more than 82,000 in 2008.  As the availability of residential lots decreased, construction of manufacturing, distribution, and retail power centers constituted much of the more recent land conversions. 

Most of the irrigated farmland remaining in the area is related to dairy operations or nurseries.  The migration of the dairy industry from Chino to the San Joaquin Valley has been accelerating with urban encroachment.
