San Diego County faces severe and recurring wildfire risk, driven by hot Santa Ana winds, steep chaparral-covered terrain, and prolonged drought. The 2003 Cedar Fire burned over 280,000 acres and killed 15 people. Earthquake risk from the Rose Canyon Fault near downtown San Diego adds a second critical threat vector.
