The fire, dubbed the Risner Fire, was 70 percent contained.
The gated community on the Los Angeles County border was temporarily threatened by the flames, authorities said. Forty homes were evacuated on St. Andrews Avenue, and Rivera and La Costa courts. Several nearby streets were placed on alert.

The Red Cross opened an evacuation center at the La Habra Community Center at 101 W. La Habra Blvd, but closed it about four hours later.
The fire was reported near Idaho Street and Risner Way at about 4:15 p.m. Los Angeles County firefighters worked to put out the blaze in the triple-digit heat with assistance from the Orange County Fire Authority.
Fire officials said the spread of the fire slowed down because it burned light brush and grass.
Los Angeles City Fire deployed one helicopter to aid in the fight and two Super Scoopers were requested.
