A 1968 report analyzing the development of Seattle-Tacoma International Airport as an air transportation hub. The document examines air traffic growth patterns, airline service routes, and the evolution of commercial aviation at Sea-Tac from 1958-1967, showing dramatic increases in passengers, cargo, and aircraft movements.

FAA’s Finding of No Significant Impact and Record of Decision for the Sustainable Airport Master Plan Near-Term Projects at Seattle-Tacoma International Airport. The document provides final agency determinations and approvals for federal actions necessary to implement 31 near-term improvement projects addressing efficiency, safety, and passenger processing needs at SEA.

This 2025 Washington Law Review article argues that Washington State's 'gift of public funds' doctrine—which prohibits governments from giving away public assets—is widely misunderstood and far less restrictive than most officials believe. The authors, both attorneys in Washington's Solicitor General's Office, explain that modern court interpretations allow governments broad flexibility to fund programs serving legitimate public purposes, and note that no appellate court has struck down any government program under this doctrine in the past 45 years. The article urges public officials and lawyers to stop letting unfounded fears about this doctrine block innovative policy solutions to problems like homelessness, childcare, and climate change.

This January 2025 technical report, prepared by Environmental Science Associates for the Port of Seattle, documents a pilot program assessing the condition and effectiveness of sound insulation previously installed in homes near Seattle-Tacoma International Airport. The report covers resident surveys, research into the expected useful life of sound insulation building materials, acoustic testing methods, and test results from selected homes. It aims to inform future decisions about repairing or replacing aging noise-reduction treatments in affected neighborhoods.

The FAA Reauthorization Act of 2024 (Public Law 118-63) is a comprehensive federal law signed on May 16, 2024, that reauthorizes and updates the Federal Aviation Administration and civil aviation programs across the United States. The Act covers a wide range of topics including aviation safety improvements, aerospace workforce development, cybersecurity, and organizational reforms within the FAA. While the law addresses airport planning and noise compatibility programs, it does not focus specifically on noise policy at individual airports such as Sea-Tac.

The FAA proposed updating its definition of 'aeronautical activity' to include unmanned aircraft systems (UAS), advanced air mobility (AAM), and commercial space launch operations, meaning federally obligated airports must provide non-discriminatory access to these emerging technologies. The policy clarifies that while these new operations qualify for airport access, the FAA retains authority to assess safety risks and set conditions for accommodating them. Recreational UAS, model aircraft, and model rockets are explicitly excluded from the updated definition.

The Commercial Aviation Coordinating Commission (CACC) submitted its final report to the Washington State Legislature in June 2023, concluding that future commercial aviation capacity needs can only be met by identifying a new greenfield airport site, as no existing finalist location gained sufficient community support. The Commission was evenly divided on whether a new facility could be operational by 2040, with most members believing completion beyond 2050 is more realistic. The report and survey results were handed off to a follow-on work group established under ESHB 1791 to continue the site selection process.

A 2022 World Health Organization report on environmental noise outlines the health risks posed by traffic, aircraft, and leisure noise, including increased risk of heart disease, sleep disturbance, and hearing impairment. The report recommends that aircraft noise levels stay below 45 dB for average exposure and below 40 dB at night to protect public health. It also defines mitigation strategies ranging from reducing noise at the source to behavior change and community education.
