Fire History
Orange County's wildfire history is defined by fast-moving Santa Ana wind-driven fires in its eastern and northern hillside communities. The 2007 Santiago Fire (28,448 acres) and simultaneous Witch Creek complex were among the most significant events. The 2008 Freeway Complex fire burned over 30,000 acres across Yorba Linda, Anaheim Hills, and Corona. The 2020 Bond Fire burned 6,699 acres in the Silverado Canyon area.
