    ★ 32
    This January 2018 report from the Port of Seattle examines the economic impact of Seattle-Tacoma International Airport, which handled an estimated 46.8 million passengers and roughly 425,860 metric tons of air cargo in 2017. The airport directly supported 19,100 on-site jobs and $5.6 billion in economic activity, while generating nearly $22.5 billion in total economic output and 151,400 jobs across Washington state when multiplier effects are included. The report also highlights the airport's role as a critical trade gateway, including the export of Washington-grown cherries to international markets.

    Port Of Seattle Commission memorandum – Airport Sustainability Master Plan

    ★
    In September 2012, the Port of Seattle Commission considered a $6 million request to create a new Sustainability Master Plan (SMP) for Seattle-Tacoma International Airport, replacing an outdated 15-year-old plan. The update was driven by nearly 50% passenger growth since the last plan, rising capacity pressures on roadways, terminals, and taxiways, and the need to meet FAA requirements for federal grants and environmental permits. The SMP aimed to guide long-term airport development through 2015, balancing future growth with sustainability goals within the airport's existing footprint.

    Aviation Mitigation Zones – HB 2276 Striking Amendment (H-3175.2/03)

    ★ 32
    A 2003 Washington State legislative memorandum outlines a proposed striking amendment to HB 2276, which would establish Aviation Mitigation Zones (AMZs) around large regional airports like Seattle-Tacoma International Airport to address noise impacts on nearby communities. The amendment would require the Port of Seattle to levy $10 million annually from 2004 to 2007 into a dedicated mitigation fund, with spending restricted to affected areas within the AMZ. An advisory board and competitive grant process would be created to help distribute funds to eligible local governments, schools, and nonprofits in impacted neighborhoods such as Burien, Des Moines, Tukwila, and Normandy Park.

    Final Staff Evaluation for SEPA Environmental Checklist – Des Moines Creek Basin Restoration Projects

    ★
    The City of SeaTac conducted an environmental review of the Des Moines Creek Basin Restoration Projects, a multi-agency effort involving the cities of SeaTac and Des Moines, the Port of Seattle, and King County. The project aims to improve water quality, reduce flooding, and restore fish habitat along Des Moines Creek by building a new detention facility, installing a high-flow bypass pipe, and maintaining low-flow water levels during dry summer months. The city's staff determined that the project does not require a full Environmental Impact Statement, as it is not expected to have a significant adverse impact on the environment.

    SR 509: Corridor Completion/I-5/South Access Road revised draft environmental impact statement and draft Section 4(f) evaluation

    ★ 32
    This January 2002 Revised Draft Environmental Impact Statement evaluates proposed improvements to SR 509 and I-5 in southwest King County, Washington, including a freeway extension to enhance southern access to Seattle-Tacoma International Airport. The study, prepared jointly by the Federal Highway Administration, WSDOT, Port of Seattle, King County, and the Cities of SeaTac and Des Moines, examines three build alternatives and a no-action alternative, differing in their proximity to Des Moines Creek Park and the airport runway protection zone. The proposed SR 509 extension corridor would be a minimum of 200 feet wide to accommodate general purpose and high-occupancy vehicle lanes in each direction.

    Final Decision on Noise Issues – Expert Arbitration Panel’s Review of Sea-Tac International Airport

    ★
    In March 1996, an Expert Arbitration Panel reviewed whether the Port of Seattle had met noise reduction requirements set by the Puget Sound Regional Council as a condition for approving a third runway at Sea-Tac International Airport. A majority of the Panel concluded that, despite the Port's extensive noise abatement programs, it had not demonstrated a sufficient reduction in real, on-the-ground noise impacts to satisfy Resolution A-93-03. This decision left the noise condition as the sole remaining hurdle for authorizing the third runway's construction.

Read This!

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.
