Parkhill area residents were allowed to return to their homes Tuesday afternoon after the Calf Fire burning east of Santa Margarita forced them to evacuate.

Cal Fire officials changed the mandatory evacuation order to a warning at 5 p.m., meaning residents could go back home but were warned to be careful of fire trucks in the area, said Capt. Ellen Price.

As of late Tuesday, the fire that blackened 640 acres of oak woodland and grass was 65 percent contained. No structures burned and one firefighter sustained a minor injury. Officials had no estimate of when the blaze will be fully contained.

The Red Cross opened a shelter Monday at Santa Margarita Elementary School for those displaced by the fire. Only one couple, Parkhill Road residents Brian and Gwen Glasgow spent Monday night at the shelter.

The couple spent Tuesday at the shelter waiting for officials to tell them they could return home and assess the extent of any damage to their property.

One reason only one couple had to use the shelter was because the Parkhill Road residents had followed Red Cross advice and put together an evacuation plan.

Many spent the night in their cars at a gathering spot in a clearing near the Cal Fire station, said shelter supervisor Doreen Ross.

“I understand the people out there were very well prepared,” Ross said. “I guess, living out in the wilderness, you have to be.”
