Images from KABC showed firefighters responding to the flames at multiple houses scattered across the neighborhood, specifically in the Aliso Woods Canyon area.
The vegetation fire broke out Wednesday afternoon, according to the Orange County Fire Authority.
Roughly two hours after it started, the blaze had grown to at least 150 acres, the authority said Wednesday evening. “We have over 60 different types of resources battling the flames,” it added.
