    Port Of Seattle in Violation of Federal Grant Assurance C.6 and State RCW 53.54.020

    ★ 32
    This document presents evidence that the Port of Seattle violated Federal Grant Assurance C.6 and Washington State law RCW 53.54.020 in connection with its FAR Part 150 Noise Compatibility Program at Seattle-Tacoma International Airport. It compiles 17 items of supporting evidence, including a 1998 congressional request for a GAO audit, state auditor correspondence, findings by Deloitte & Touche identifying violations from 1990 to 1994, and records showing the Port received over $100 million in federal funds tied to noise mitigation commitments it allegedly failed to honor. The materials illustrate the consequences for surrounding communities and governments that held land-use authority under the noise compatibility planning process.

    Homeowner handbook

    ★ 32
    The Port of Seattle's Homeowner Handbook is a guide for residents participating in the Sea-Tac Airport Noise Remedy Program, which provides sound insulation improvements to affected homes. It walks homeowners through a 14-step process covering everything from attending an initial briefing and scheduling an inventory audit, to overseeing contractor bidding, managing construction, and signing off on completed work. The handbook was prepared by the Port of Seattle Noise Remedy Staff and last revised in June 1997.

    Ep #38 Aviation Forum Postgame (Raw!)

    What if the solution to decades of airport noise and community impacts has been hiding in plain sight all along? In this open letter to city managers across airport communities, we revisit a landmark yet largely forgotten document: the Sea-Tac Communities Plan of 1976. Built on the Port of Seattle's promise — *"As we do better, you'll do better"* — this collaborative plan was supposed to be the long-term answer for neighborhoods living under the flight path. So why has it been reduced to little more than an expensive property buyout program? The answer reveals a critical gap that neither elected officials nor community advocates can fill alone. Real, lasting solutions require sustained professional commitment to airport community planning — something that should have been established 50 years ago. If you work in city management, this episode speaks directly to you and the unique role only you can play in finally delivering on that broken promise.

    Ep #36 Orphans

    **Discover why environmental progress stalled for airport communities while cars got cleaner** Ever wonder why your car's emissions have dramatically improved over decades, but aviation seems stuck in the past? In this eye-opening episode of The Airport Communities Podcast, we explore the fascinating tale of two environmental paths that diverged after 1970. While Washington Senator Scoop Jackson spearheaded NEPA—one of the largest expansions of environmental policy in American history—and California secured game-changing carve-outs in the Clean Air Act that led to massive air quality improvements, aviation somehow got left behind. Despite Boeing being headquartered in Washington, aviation environmental standards never caught up. UW Meteorologist Cliff Mass delivers some stark perspective: those two annual flights to Europe generate more greenhouse gases than most people produce in their entire homes over a year. Meanwhile, Boeing's monopoly status has eliminated market incentives for cleaner technology. This wasn't an oversight—it was intentional. Today, every airport community continues paying the price for decisions made decades ago that exempted aviation from automotive-level engineering standards.

    PSSB 5652: An Act Relating to Reducing Environmental and Health Disparities and Improving the Health of Washington State Residents in Large Port Districts

    Washington State legislation (PSSB 5652) aimed at reducing health and environmental impacts on communities near Sea-Tac Airport, where residents face disproportionate exposure to aviation-related air pollution and noise linked to serious health conditions. The bill establishes a grant program to fix failed noise-mitigation home improvements (known as 'port packages') and fund new mitigation strategies, while directing the University of Washington to conduct ongoing air quality and noise assessments every two years. It also requires the State Auditor to evaluate the Port of Seattle's noise mitigation efforts and directs the Department of Commerce to administer a mitigation grant program using the State Aircraft Noise and Air Quality Mitigation Account.
