Several fire departments Saturday extinguished a grass fire in the coastal hills of Annapolis.

Cal Fire air attack, tankers and a helicopter responded as well as several engines from Cal Fire and at least four other agencies to the fire off of Brushy Ridge Road.

The fire was stopped at less than a half-acre, a Cal Fire official said.

It was reported at about 1:10 p.m. and was contained at 2:15 p.m.

It burned in a very rural residential area off of Annapolis Road.

The cause remained under investigation Saturday.

Cal Fire firefighters were joined by Sea Ranch, Timber Cove, Annapolis and South Coast volunteer firefighters.
