to resource management requirements. Because of the area's history as a military training base, some military debris including unexploded ordnance remained in the area when it was developed, in spite of multiple cleanup efforts by different branches of the services. In 1983 two 8-year-old Tierrasanta boys were killed after discovering unexploded ordnance in a canyon near their home. The military has performed clearance operations as recently as 1994 and the U.S. Army Corps of Engineers continues to investigate the area every five years under its FUDS Formerly Used Defense Sites program. 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. Geography The developed part of Tierrasanta, which rises from west to east and includes numerous canyons, is situated like an island, not directly bordered by any other community. It is bounded on the north by the Mount Soledad (52) Freeway and the sprawling southern fields of MCAS Miramar; on the east by the Mission Trails Regional Park, which has numerous hiking and mountain biking trails; on the west by slopes overlooking the wide Interstate 15 corridor running from Friars Road to Route 52, and on the south with homes overlooking the Admiral Baker Golf Course and the San Diego River. Community activities focus on the Tierrasanta Recreation Center, which includes lighted sports fields, a large swimming pool, tennis courts managed by the Tierrasanta Tennis Club, a gymnasium, and meeting rooms. Numerous green belts with walking paths run through the canyons, and are maintained by the Friends of the Tierrasanta Canyons. There are a number of entrances to Mission Trails Regional Park, including an entrance with parking at the eastern end of Clairemont Mesa Boulevard. Like most of the coastal areas in Southern California, the natural habitat in the canyons and other undeveloped areas within Tierrasanta, as well as in much of MCAS Miramar and Mission Trails Regional Park, is coastal sage scrub and chaparral.
