Boulder County crews were able to quickly contain and knock down a small grass fire just yards from a student parking lot at Monarch High School in Louisville this afternoon.

The fire was reported around 11:50 a.m. today just southeast the school at 329 Campus Drive in Louisville. Within an hour, personnel on scene said the fire was controlled and crews were mopping up a few hot spots.

“The responders did an excellent job,” said Michelle Kelly, a spokeswoman with Rocky Mountain Fire.

Kelly said crews estimated the fire was about 2 to 5 acres in size and that one building and several cars were possibly threatened. No structures, however, were burned.

Crews shut down 96th Street between Dillon Road and Northwest Parkway due to the fire, but there were no disruptions at Monarch High.

Most of the area burned was in Louisville, but some was in unincorporated Boulder County, officials said.

Kelly said there was no apparent cause for the fire yet, but did say wind gusts in the area fanned the flames once they started.

“The winds were definitely a factor,” Kelly said.

Louisville Fire Department, Lafayette Fire Department, North Metro Fire and Rocky Mountain Fire all responded to the call.
