PITTSBURG, Calif. (KRON) — Fire units responded to a three-alarm brush fire in Pittsburg that burned 18 acres on Tuesday afternoon, Cal Fire said. The fire was at Golf Club Road and Golf Club Court.

The Contra Costa County Fire Protection District said at 6:24 p.m. that the fire had been contained. CCCFPD later said that the fire started at an encampment.

CCCFPD placed defense crews along Orinda Circle to defend homes in the area. It said although fires burned in some some yards, all structures have been protected and no evacuation orders were issued.

CCCFPD said it has responded to the area frequently due to lots of dry vegetation. People are asked to be cautious when driving in the area.

Cal Fire assisted CCCFPD in fighting the blaze.
