A two-alarm vegetation fire burned a dozen acres before being contained Sunday afternoon in the Santa Ynez Valley, according to the Santa Barbara County Fire Department.

The blaze broke out at about 1 p.m. near Firestone Vineyards on Zaca Station Road, Fire Capt. Dave Zaniboni said.

He said the first crews on the scene called for additional firefighting resources, including two water-dropping helicopters.

After about two hours, the fire was contained at about 12 acres, Zaniboni said.

One structure was briefly threatened by the flames, but firefighters were able to keep it from being damaged.

No injuries were reported, and the cause of the fire remained under investigation, Zaniboni said.
