Noise Abatement Procedures
Noise abatement procedures are voluntary and 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 (ATC) 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 425-284-0500 or fill out our online form.

- Enter Class D Airspace from the suggested reporting points as shown on the map at or above 1600' MSL
- Runway 16R-34L, Runway 16L-34R: Remain as high as practical until intercepting the VASI, PAPI or glide slope unless otherwise directed by ATC
Departures
- Itinerant departures allowed on Runway 34R with ATC permission
- On initial climb-out, fly runway heading to 1100' MSL or higher before turning, unless otherwise directed by ATC
- Runway 16L-34R: Avoid intersection departures
- Maintain 1600' MSL or higher until leaving the Class D Airspace
