Orange County firefighters Wednesday were battling a brush fire in Aliso Wood Canyon.
Firefighters were called at 2:44 p.m. to the brusher between Laguna Niguel and Laguna Beach near a water treatment plant, Orange County Fire Authority Capt. Sean Doran said.
The fire was estimated to be about three acres as of 3:30 p.m., Doran said.
At least one water-dropping helicopter was helping fight the flames, and crews on the scene were requesting a fixed-wing aircraft to assist. The flames were not immediately threatening any structures in the remote area.
