Rancho Bernardo's History
Early History of the Area
People lived in this area for a long time, from about 850 CE to 1790 CE. The Kumeyaay people are believed to have lived here. There are also signs that the Luiseño people were present.
During a later period, there was a village called the Westwood Valley complex. It was located along a stream that sometimes dried up. The Kumeyaay likely called this village Sinyau-Pichkara. Today, this village area is under the western part of Rancho Bernardo, near Duenda and Poblado Roads.
Modern History and Development
Rancho Bernardo is part of what was once a large Mexican land grant called Rancho San Bernardo. This land was granted between 1842 and 1845.
In the 1960s, San Diego officially added Rancho Bernardo to its city limits. A company called AVCO Community Developers helped build up the area until 1984. The Rancho Bernardo Inn, a well-known hotel, opened in the middle of the development in 1963.
On October 22, 2007, a large wildfire called the Witch Creek Fire swept through Rancho Bernardo. It also affected other parts of San Diego County. The fire destroyed hundreds of homes, especially in neighborhoods that were hard for firefighters to reach. Strong winds made the fire spread very quickly. The neighborhoods most affected in Rancho Bernardo were The Trails, Montelena, and Westwood.
