A 2020 study gathered input from 48 community stakeholders near Seattle-Tacoma International Airport, finding that while residents valued the economic benefits, jobs, and convenient access the airport provides, noise and air quality were the top concerns—especially for those living to the south and west under flight paths. Stakeholders raised issues including late-night flights, NextGen procedures concentrating aircraft noise, ultrafine particle pollution, and the limitations of existing noise mitigation programs. Traffic congestion and potential public health impacts from aircraft emissions were also frequently cited challenges.

This document examines how Seattle-Tacoma International Airport and comparable U.S. airports handle community noise and growth impacts, using Boston Logan International Airport as a key case study. It outlines federal NPIAS guidelines requiring airports to balance aviation needs with community and environmental concerns, and details Boston Logan's noise abatement measures — including nighttime flight restrictions, soundproofing programs, and a 24-hour noise hotline — as models for addressing residential noise complaints. These examples provide context for evaluating Sea-Tac's own noise policies and community compatibility efforts.

This background section traces the history of Seattle-Tacoma International Airport from its origins as a World War II military airfield to its current status as the eighth busiest U.S. airport, handling 51.8 million passengers in 2019. It covers key milestones including the airport's 1949 opening for commercial service, the controversial addition of a third runway in 2008, and the surrounding communities that have been affected by the airport's growth. The document also outlines the Port of Seattle's future expansion plans under its Sustainable Airport Master Plan, which aims to accommodate nearly 500,000 operations and 56 million passengers annually by 2027.

A comprehensive study examining the current and ongoing effects of Seattle-Tacoma International Airport operations. The study was prepared for the Washington State Department of Commerce as authorized by ESSB 6032 and conducted by Stantec consulting firm.

A 2020 Washington State study, funded by the legislature and six nearby cities with a combined $600,000 budget, examines how Seattle-Tacoma International Airport's operations have historically affected surrounding communities including Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila. Unlike a similar 1997 study that projected future impacts from a proposed third runway, this study reviews historical data from 1997 to 2019 to establish a baseline of airport-related impacts across a range of metrics. The study area covers about 61 square miles and is home to over 237,000 residents, a population density roughly 3.3 times greater than the King County average.

A 2020 study evaluated the positive, negative, and neutral effects of Seattle-Tacoma International Airport on six nearby cities — Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila — using data spanning 1997 to 2019. The study found that noise was the top public concern, followed closely by air quality issues from aircraft operations, along with traffic congestion and distrust of the FAA and Port of Seattle. Researchers attempted to distinguish between impacts directly caused by airport operations and those resulting from the broader regional population growth that roughly doubled over the same period.

This 2020 report examines the socio-economic conditions in six south King County cities near Seattle-Tacoma International Airport, including Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila. It analyzes demographic trends such as population growth, age distribution, and ethnic profiles from 1997 to 2018, finding that most study area cities grew more slowly than King County overall, with Burien being a notable exception largely due to a 2010 annexation. The report is part of a broader study assessing how airport operations affect surrounding communities across indicators including income, housing, education, employment, and municipal tax revenues.

This 2020 public health study examines the effects of Seattle-Tacoma International Airport operations on nearby communities, analyzing health indicators such as cancer, heart disease, and Alzheimer's disease death rates between 2012 and 2016. Study area cities like Burien, Des Moines, Federal Way, SeaTac, and Tukwila generally showed higher cancer and heart disease death rates than King County as a whole, though rates declined somewhat over the period. The report aims to identify whether airport operations contributed to adverse health outcomes and recommends strategies for ongoing investigation and mitigation.

The Burien Airport Committee held a virtual meeting on May 19, 2020, to discuss airport-related policy matters, including a proposed letter to Port Commissioners about a 'new normal' for airport operations, comments on a Department of Commerce report, and a possible invitation to an FAA Community Ombudsperson. Draft minutes from the April 21, 2020 meeting were also reviewed, covering Chair Tosta's Washington, D.C. visit to advocate for a comprehensive cumulative impact assessment of the Port of Seattle's Sustainable Airport Master Plan (SAMP). The meetings, held via Zoom due to COVID-19 restrictions, reflect ongoing community and city council efforts to address noise and environmental concerns related to Sea-Tac Airport.
