The cause of the fire that burned 42 acres on Tepusquet Road Tuesday night is still under investigation, according to the Santa Barbara County Fire Department.

Capt. Mike Gray of County Fire said the fire is fully contained, and crews are finished working at the site.

The department updated the number of acres burned after helicopters were able to fly above the area to get a better view of the fire’s path. The initial estimate was between 15 to 20 acres burned.

Fire crews responded to the fire on the 4500 block of Tepusquet Road, east of Santa Maria, at 7:23 p.m. on Tuesday. Personnel from the county and Santa Maria City fire departments stopped forward progress of the blaze around 9:45 p.m.

Gray said the County Fire Department is also monitoring the area to ensure that rain doesn’t cause flooding, which is more common after vegetation fires due to the loss of plants that keep the soil together.

“That’s always a concern with any brush fire, but we have crews that remediate the area to help with any flood issues,” Gray said.

Gray also recommended that all Santa Barbara County residents sign up for ReadySBC.org to get alerts to their phones if a fire breaks out.

Officials initially ordered evacuations for the blaze, with emergency personnel going property to property to warn residents in the area. They downgraded to evacuation warnings and then lifted those when crews got the upper hand on the flames Tuesday night.
