What Should I Know About Aircraft Noise in Boulder?
Please note that aircraft in flight are under the jurisdiction of the Federal Aviation Administration (FAA) and cannot be controlled by the City of Boulder. Additionally, the airport is open 24/7 with no curfew or other restrictions on activity. No-fly airspace does not exist within the Boulder Valley though FAA regulations prohibit flights under 1000 feet above populated areas, except for take-offs and landings and air ambulance helicopters.
However, in an effort to reduce the impacts of aircraft noise, the city operates a Voluntary Noise Abatement Program that encourages operators at the airport to minimize noise.
