“People are trapped on their properties due to the roads,” said Captain Greg Barta. “Up there the roads are very narrow, inaccessible in many spots. When this mud comes down it blocks the road.”

Rescue units, which included two Swiftwater rescue teams, from Orange County Fire Authority, waded through the fast-moving water, mud and debris to rescue trapped residents. The OCFA has not reported any injuries.

The roads entering Silverado Canyon have been closed until further notice as crews work to clear the area of mud and debris. The area around Silverado, Modjeska and Williams Canyons was burned by the Bond Fire last year which scarred the landscape.

There is no timeframe when residents can re-enter the area. Residents have parked on the shoulder of Santiago Canyon Road, waiting for crews to allow back to their homes.
