During a Monday afternoon press conference, Orange County Fire Authority Fire Chief Brian Fennessy said the Silverado Fire has yet to damage any  structures.

“We’ve been very fortunate not to have lost any structures, yet. A lot of that has to do with all the great work our citizens have done within the City of Irvine, the brush clearances — everything we’ve asked for in terms of defensible space, really led to a lot of success in terms of a lack of structure loss within the city of Irvine,” Fennessy explained.

While the size of the Silverado Fire, in terms of acreage, has doubled in less than a day, Fennessy explained that most air support has been grounded due to high winds.

Adding that ground crews are essential for knocking down the blaze, once air crews have dropped fire retardant from above.

“Yes, we flew aircraft early on in the incident, it became much too windy, much too bumpy and the air tactical group supervisors called off all the aircraft and they’ve largely been sitting on the ground all day,” he said. “Once the velocity of the wind diminishes, to point where it’s safe to be flying — they will be flying.”
