In October 2003, Tierrasanta, among other communities in San Diego, was affected by what was known as "Firestorm 2003." This was a conglomeration of the Cedar Fire and numerous other wildfires that converged on Southern California. The residents of Tierrasanta were forced to evacuate. Nearly a dozen homes were lost to the blaze. Shortly after, in 2004, the Tierrasanta Community Emergency Response Team (T-CERT) was created for rapid local response to natural disasters. A similar scare swept through Tierrasanta in the fall of 2007, though residents were not required to evacuate.
