The fire started around noon on Saturday north of Jamestown, according to Gabi Burkircher, a spokeswoman for the Boulder Emergency Management Officer. About 900 homes are in the evacuation area, according to a tweet from the Boulder Emergency Management Agency.
Jamestown is located in the foothills of the Rockies, about 14 miles northwest of Boulder and about 43 miles northwest of Denver.
The fire is being compressed by winds to the southeast, Berkircher said.
“We are asking people almost anywhere in the area to be sure they are drawing up an evacuation plan,” Berkircher said, adding that the local disaster declaration was signed around 1:30 p.m. local time in response to the fire.
An evacuation is scheduled for Jamestown, and pre-evacuation orders are in place for areas south of the city, Burkircher said.
No deaths or injuries were reported, and the cause of the fire on the wood has not yet been determined, Burkircher said.
