A vegetation fire burned several acres of hillside at the base of the Cuesta Grade on Tuesday, forcing evacuations of homes in the area before a quick response corralled the flames.

The fire sparked at 10:17 a.m. near Hawk Hill Lane off southbound Highway 101, according to the emergency response app PulsePoint.

Cal Fire said in a social media post at 11 a.m. that they were “making great progress” and the fire was less 60 acres.

At 11:40 a.m., Cal Fire spokesperson Toni Davis told The Tribune the fire was 5% contained.

By 12:15 p.m., the WatchDuty app reported the fire had been mapped at 13.7 acres and noted that all air resources had been released.

Fire threatened structures

Dispatchers initially reported on the emergency scanner that the fire had the potential to grow to 200 acres and was spreading uphill “at a moderate rate of speed.”

At least two structures were threatened, Cal Fire said, while also noting on the radio that pedestrians on a nearby hill were in the way and hindering drops from firefighting aircraft.
