A wildfire broke out on February 7, 2006 in the Cleveland National Forest, the National Forest that separates Anaheim Hills from the Riverside County Border. This fire grew and firefighters were unable to contain it due to winds and temperatures. On the morning of February 9, 2006, the fire worsened, which forced the evacuation of a large section of Anaheim Hills. Nearly 75% of the Community of Anaheim Hills was either under voluntary or mandatory evacuation. This resulted in the closing of two local elementary schools for two days, and several other schools served as shelters for the evacuees during the day.
