The Borrego Valley is a 70 square-mile privately owned area surrounded by the Anza-Borrego Desert State Park. Agriculture became an important activity in the Valley during the years following World War II, however, by the mid-1960s agricultural pursuits had become less profitable and private planning efforts began to investigate other opportunities.
The environment of the Borrego Valley is its greatest natural resource, and the warm, mild winters make it a prime location for resort development. Clean air, clear skies and proximity to the Anza-Borrego Desert State Park are also major factors which add to Borrego Valley's potential as a high-quality and profitable winter resort.
