The fire started before 4 a.m. near Lee Hill Drive and Deer Trail Road, approximately 8 miles northwest of the city of Boulder.
An evacuation warning was sent to 176 residents in the Surrey Ridge and Carriage Hills area. No residents were forced to evacuate.
BCSO, Boulder Mountain Fire, Lefthand Fire Protection District, Boulder Rural Fire Protection District, Sunshine Fire Protection District, Boulder Fire-Rescue, and Boulder Emergency Squad all responded to fight the fire.
Firefighters created a line around the fire, and it was contained shortly before 5:30 a.m.
BCSO said the fire burned half an acre and no injuries were reported. No structures were impacted either.
“We’ve kind of been planning for this wind event, so people were up staffing their engines, putting their resources on notice,” Seth McKinney, fire management officer for BCSO, said. “It was a good coordinated attack by a lot of different agencies that we were able to get a handle on it pretty quick.”
The fire was caused by a downed powerline, BCSO said.
“Given recent events in Boulder County, we’re really taking no chances with the evacuations, and we try to be as deliberate as we can about that,” McKinney said. “We don’t want evacuations causing more mayhem than it needs to, so we had a targeted area that we worked with law enforcement on.”
