JURUPA VALLEY (CBSLA.com) — Crews have made progress containing a brush fire that scorched 311 acres and damaged two structures on the Jurupa Valley side of the Santa Ana River bottom.

The fire, which broke out about 4:45 p.m. Thursday, was 60 percent contained by 7 p.m. Friday, Riverside County Fire officials said.

Crews expect to have the fire fully contained by Saturday night.

“They have some contingency plans if winds do surface and they start getting flare-ups,” Greg Birchfield of Cal Fire said. “They have a helicopter standing by just in case.”

The riverbed is overgrown with trees and bushes, and neighbors say they’ve seen it all before.

“This is our fourth or fifth fire down here. Wasn’t real worried about it,” resident Bill Shields said.

But the wind grabbed this fire and pushed it through the riverbed last night. At least one outbuilding caught fire and scared off Shields’ horses, which returned Friday.

No injuries were reported and no homes were lost in the fire.
