A mandatory evacuation order was lifted Saturday night, hours after thousands were forced from their homes in the Stevenson Ranch area as firefighters battled an out-of-control brush fire that erupted in the Santa Clarita Valley earlier in the day, authorities said.
The so-called Sage Fire broke out near Calgrove Boulevard and the Old Road shortly around noon, according to the Los Angeles County Sheriff's Department.
Two hundred Los Angeles County Fire Department personnel, as well as 10 aircraft, were at the scene battling the blaze, according to a sheriff's news release.
Within 90 minutes of erupting, the fire had scorched 75 to 100 acres, said Vanessa Lozano of the Fire Department. She described the fire as "slow burning."
By 7:30 p.m., the fire had grown to 800 acres and was 15 percent contained. At that time, at least 700 homes in Stevenson Ranch were under a mandatory evacuation order, according to fire officials.
The evacuation order on all homes was lifted at 9:30 p.m., according to tweet from the Fire Department. Only residents with identification were being allowed to return.
An evacuation center had been set up at West Ranch High School at 26255 W. Valencia Blvd. in Stevenson Ranch.
The Old Road was closed between Lyons Avenue and Laurel Crest Lane, according to the California Highway Patrol.
An inmate firefighter suffered a minor injury, according fire officials. No other injuries were reported.
The cause of the fire was under investigation.
