MOORPARK – Arson investigators determined Wednesday that power lines caused the weekend wildfire that destroyed five homes. “Power lines,” said Capt. Barry Parker of the Ventura County Fire Department. “All I can tell you right now is the fire was caused by power lines. We know the cause, but the investigation can go on for a week, maybe a month.” The Fire Department’s Arson Investigation Unit made its preliminary determination after sifting through ashes within the 13,600 acres destroyed by the blaze. Parker did not say whether investigators had seen downed power lines where the fire began at 2:30 a.m. Sunday near the former Egg City production plant at Grimes Canyon and Shekell roads north of Moorpark.

The cost of battling the fire was estimated to reach $4.5 million. Neighbors off Grimes Canyon Road had reported a power outage about the same time the 2:30 a.m. fire was first reported. A Southern California Edison spokesman said the company has been notified by Ventura County fire officials about the cause. During the fire, company officials said, power was knocked out at several hundred homes, with others experiencing momentary outages while the wildfire raged. “We do have poles that were damaged in the fire,” said Edison spokesman Steven Conroy. “We’ve been officially notified and have instigated an investigation in cooperation with Ventura County fire officials.” [email protected] (818) 713-3730160Want local news?Sign up for the Localist and stay informed Something went wrong.
