SEA Part 150
Noise Study
Join Us for the Virtual Part 150 Noise and Land Use Compatibility Study Workshop
The Port of Seattle invites you to attend a virtual public workshop to learn about the Part 150 Study for Seattle-Tacoma International Airport (SEA). The multi-year study evaluates SEA’s aircraft noise compatibility with the surrounding communities and current and possible new efforts to reduce the effects of aircraft noise on these communities. This voluntary study follows the Federal Aviation Administration’s regulatory process.
Three in-person workshops were held earlier this month. These workshops share information on the study’s timeline and current and projected aircraft noise levels in the surrounding communities. Attendees will have the opportunity to offer feedback on the draft Noise Exposure Map (NEM) report and suggest potential noise reduction measures for evaluation within the study.
Need language interpretation, special accommodations under the Americans with Disabilities Act, or questions answered? Contact the Noise Programs office at 206-787-5393 or P150@portseattle.org. Please submit all requests seven business days in advance of the workshop.

Project Overview
The Port of Seattle will begin a new multi-year Part 150 Noise and Land Use Compatibility Study update for SEA Airport in 2024.
A Part 150 Noise and Land Use Compatibility Study is a voluntary FAA program that sets guidelines for airport operators to document aircraft noise exposure, and to establish noise abatement and compatible land use programs. These noise abatement procedures and/or mitigation programs must be approved by the FAA in order to qualify for potential federal funding. This will be the fourth Part 150 update undertaken at SEA Airport since the initial study was conducted in 1985.
The study identifies and evaluates two components, (1) aircraft noise levels and (2) land uses, during two distinct phases of this study:
- Noise Exposure Maps (NEM) phase – contour maps are produced showing existing and future aircraft sound levels using the FAA-required 65 DNL noise metric.
- Noise Compatibility Program (NCP) phase – measures recommended in an NCP are designed to reduce noise and incompatible land uses within the noise exposure area. These may include noise abatement measures, noise mitigation measures such as sound insulation programs, and/or preventative measures.

Study Kickoff Workshops
The study will include extensive public engagement throughout the process. To begin these efforts, the Port held three Study Kickoff Workshops in June 2024. The workshops were in an open-house format where the public was encouraged to attend and participate. The workshops occurred on: June 5th, 2024 from 6:00 to 8:00pm at Gregory Heights Elementary School in Burien, June 6th, 2024 from 6:00 to 8:00pm at Mount Rainier High School in Des Moines, and on June 8th, 2024 from 10:00am to noon at Glacier Middle School in SeaTac. Workshop materials are available in the Documents section of this website.
