General Debris Cleanup Information

Illegal Dumping

Flood debris should not be placed on roadsides as it will not be collected. Placing debris on the roadside may be considered illegal dumping, which is subject to penalty. To report illegal dumping, contact the Boulder County Sheriff’s Office at 303-441-4444.

Woody/Vegetative Material

There are several locations throughout Boulder County that accept yard waste at reduced rates. Visit the Yard Waste Drop-Off website for more information.

Open Burning of Flood Debris

The Boulder County Sheriff’s Office is asking residents to use caution before burning vegetative flood debris. Burning of flood debris can be a health hazard, and the smoke can impact air quality. Much of the flood debris is illegal to burn without a permit. For example, it is illegal to burn material that is wet or full of soil, construction debris, and/or trash. A permit is required to burn clean, dry tree branches that are less than 6 inches in diameter. To apply for a permit and to learn more, visit the Burn Permit website.
