Noise Abatement Procedures

Noise abatement procedures are designed to minimize exposure of residential areas to aircraft noise, while ensuring safety of flight operations. There are communities surrounding the airport which are noise sensitive. We want to minimize the noise impacts on these communities. The procedures described herein are intended for noise abatement procedures and are subject to air traffic control and pilot discretion for reasons of safety.

To contact airport operations regarding a specific noise incident or to express your concerns about aircraft noise in general, call the Noise Hotline at 425-353-2110 ext. 1, send an email, or fill out our online form.
