  • It’s A Disaster

    With the emergence of Coronavirus, we’ve noticed a great deal of Schadenfreude among airport activists across the world. Comments such as “It’s so quiet now. We should have an outbreak like this all the time!” The thing most residents forget is that we actually did twenty years ago. It was called ‘9/11’. If you look

    Late night noise reduction programs take effect

    In September 2019, the Port of Seattle announced two new programs to reduce late-night aircraft noise at Seattle-Tacoma International Airport. A revised Runway Use Agreement with the FAA took effect on September 4, limiting use of the Third Runway (16R/34L) between midnight and 5 a.m., while a new voluntary Late Night Noise Limitation Program encourages airlines to schedule flights during less noise-sensitive hours or switch to quieter aircraft during the same period. Both initiatives stemmed from recommendations by the Sea-Tac Airport Stakeholder Advisory Round Table (StART).

  • The problem with cities

    As one attempts to survey the landscape concerning the various negative impacts that the Sea-Tac Airport has foisted upon the surrounding communities, one quickly becomes aware of a black hole which I call ‘The Dark Time’–probably because I watched too many comic book movies with my kids. The Dark Time is the roughly decade-long period

    Westside Beautification – Port of Seattle style

    A political cartoon by artist Kelliher depicting a massive bulldozer labeled 'Destruction Construction Company' destroying trees planted by Scouts, while a figure labeled 'Port of Seattle' holds an 'Airport Landscaping Plan' and tells an off-panel character 'Don't let the Scouts bother you — we got a lot of beautifying yet to do.' The caption reads 'Westside Beautification - Port of Seattle style,' satirizing the Port of Seattle's land-clearing activities around Sea-Tac Airport in conflict with community beautification efforts.

    Port Of Seattle airport neighbor community accords [proposed]

    The Port of Seattle Airport Neighbor Community Accords (proposed November 2018) is a citizen-drafted proposal calling on the Port of Seattle to prioritize the health and well-being of communities surrounding Sea-Tac International Airport. It argues that these neighborhoods bear an unfair burden from aircraft noise and environmental impacts without adequate compensation, and that the Port's 2018 bylaw changes weakened its commitments to quality of life, environmental stewardship, and community collaboration. The document outlines six specific accords, including demands for independent audits of mitigation spending, a nighttime curfew, prioritization of tax levy funds for community mitigation, and reduced use of the 3rd runway until mitigation goals are met.

    Federal Way Mayor’s Quiet and Healthy Skies Task Force Report

    The Federal Way Mayor's Quiet and Healthy Skies Task Force Report, published August 2, 2018, examines how increased flight operations and Sea-Tac International Airport's third runway have worsened aircraft noise and air pollution for Federal Way residents. The report evaluates potential remedies such as changes to flight paths, glide slopes, and schedules, while also analyzing legal authority over cargo flight curfews and reviewing the airport's Sustainable Airport Master Plan. It concludes with recommendations aimed at reducing the disproportionate noise and health burdens placed on Federal Way communities.

    Federal Way Mayor’s Quiet and Healthy Skies Task Force Report

    The Federal Way Mayor's Quiet and Healthy Skies Task Force Report (August 2018) examines the noise and health impacts of Seattle-Tacoma International Airport's Third Runway on Federal Way neighborhoods. It presents runway usage statistics from 2007–2017 showing a dramatic rise in flight operations, and references a 1997 impact mitigation study that identified over $148 million in recommended sound insulation and avigation easements for Federal Way communities affected by overflight noise.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
