Fire officials made quick work of a brush fire Saturday afternoon that ignited near Highway 14 just south of Agua Dulce Canyon Road. The fire was reported at 4:50 p.m. and was knocked down less than 30 minutes later after burning just one acre. Three helicopters were called out to help extinguish the fire, which was burning downhill in light brush. Wind was not a contributing factor in the fire. “We (did) have air support on that incident,” said Supervisor Cheryl Sims with L.A. County Fire. All aircraft have since been called off the incident. It was knocked down around 5:18 p.m.
