Crest / Dehesa / Granite Hills / Harbison Canyon


The Crest, Dehesa, Granite Hills, Harbison Canyon Subregion is located in the southwest quadrant of San Diego County. The area consists of approximately 33 square miles including the communities of Crest, Granite Hills, Dehesa and Harbison Canyon. Included within the area, but autonomous, is the 640 acres Sycuan Indian Reservation.

The subregion is bordered by Lakeside to the north, Alpine to the east, Jamul to the south and El Cajon to the west. The area is geographically diverse, containing within its boundaries, steep mountains, massive rock formations, rolling hills, open valleys and deep canyons. The Sweetwater River system with its tributaries (North Fork, Sycuan Creek, Harbison Canyon Creek) as well as Forester Creek, which drains to the San Diego River, are all within the Plan Area. A variety of flora and fauna exists and archaeological formations, especially those relating to Indian settlements, abound.

Dehesa was originally homesteaded in the 1860s and became known for its extensive production of grapes, olives and fruits. The ridge-top community of Crest was developed as a planned cabin subdivision (Suncrest) in the 1920s. Harbison Canyon, located in the upper reaches of Dehesa Valley, was developed as a recreational subdivision in 1926. Granite Hills is almost built-out at rural densities and it forms an effective transition between the estate and rural uses in the Subregion and the highly urbanized City of El Cajon.
