Why it matters

The incident raises questions about fire prevention, fuel mitigation, and emergency preparedness in rapidly growing communities on the urban-wildland interface.

The details

According to Thornton Fire Department officials, the fire began as a smoldering mulch fire that quickly grew out of control after firefighters arrived on scene.

The blaze ended up burning up to 10 acres, destroying 75-100 vehicles, and damaging at least 5 businesses before firefighters were able to contain it. Mitigation efforts around a bike path were credited with helping slow the fire's northward spread towards residential areas.
