NAPA COUNTY, Calif. – Downed power lines were ruled the cause of two Sunday structure fires in unincorporated Napa County.

Firefighters responded to the blazes early Sunday evening, according to Cal Fire Battalion Chief Pete Muñoa, who also serves as Napa County fire marshal.

Just after 6 p.m. Cal Fire units and the Napa County Fire Department were dispatched to power lines down at 360 Clark Way, Angwin in unincorporated Napa County, Muñoa said.

When personnel arrived at the location, they observed dark smoke emitting from the 900-square-foot residence. Muñoa said firefighters took action and opened up the ceiling in the kitchen area as well as an exterior wall to find the fire actively burning.

He said their aggressive suppression efforts confined the fire to those areas, resulting in approximately $40,000 in damage but $110,000 in property saved.

During salvage and overhaul operations a second fire was reported at 358 Clark Way, a 2,100-square-foot duplex next to the original incident, Muñoa said.

Firefighters already at the scene initiated a fire attack and discovered a fire in the wall of the middle bedroom which they quickly extinguished, he reported. Damage was estimated at $15,000 with $230,000 in property saved.

Muñoa said investigators from Cal Fire and the Napa County Fire Marshal’s Office determined both of the fires to have been caused by an electrical malfunction from the downed power lines.

The Red Cross was called in to assist the displaced residents. No injuries were reported, he said.
