    SR 518 corridor planning study

    In November 2019, the Washington State Department of Transportation (WSDOT) presented findings from the SR 518 Corridor Planning Study to the Highline Forum in Des Moines, WA. The study, mandated by a 2017 legislative proviso and funded with $500,000 from the legislature plus an additional $400,000 from the Port of Seattle, examined traffic conditions and improvement alternatives along the SR 518 corridor near Sea-Tac Airport. The presentation covered traffic analysis, alternatives screening, and recommended improvement packages, with a final report due by November 30, 2019.

    The Regional Transportation Plan — 2018

    The Regional Transportation Plan — 2018 is a draft planning document produced by the Puget Sound Regional Council (PSRC) in May 2018, outlining the regional transportation vision and investment priorities for the greater Puget Sound area, including King, Pierce, Snohomish, and Kitsap counties. Funded in part by federal transportation agencies and Washington State, the plan addresses multimodal transportation networks including roads, transit, and non-motorized travel. Note: this document does not specifically address Sea-Tac Airport noise policy and may have limited relevance to airport noise concerns.

    The Regional Transportation Plan — 2018: Executive summary

    The Puget Sound Regional Council's 2018 Regional Transportation Plan outlines how the central Puget Sound region, which has seen rapid population and job growth since 2010, intends to manage an additional one million residents by 2040. The plan details major investments across highway, transit, rail, ferry, bicycle, and pedestrian systems to reduce traffic congestion and better connect housing, employment centers, and freight hubs. It aims to provide equitable access to the region's natural, cultural, and recreational assets while keeping the transportation system sustainable through projected growth.

    Airport drives traffic enhancement briefing

    This 2018 Port of Seattle briefing outlines near-term traffic mitigation strategies for Sea-Tac Airport's increasingly congested roadway system, which was originally designed for 5 million annual passengers but now handles far greater volumes. Key measures include a Traffic Mitigation Plan that restricts access to southbound airport freeways during peak periods, and a new TNC 'Re-Match' program that allows rideshare drivers who have just dropped off passengers to immediately pick up new ones without returning to the remote 160th Street holding lot. The Re-Match pilot reduced passenger wait times by one-third and eliminated an estimated 30,000 deadheading trips in December 2017, while also reducing expressway congestion near the terminal.

    Amendment No. 3 to Port Of Seattle and City of SeaTac 2005 Interlocal Agreement (ILA-2)

    This is Amendment No. 3 to a 2005 Interlocal Agreement between the Port of Seattle and the City of SeaTac, entered into on February 16, 2006, governing transportation planning and funding around Seattle-Tacoma International Airport. The amendment updates project management responsibilities and budget allocations for capital improvement projects, including the South Access roadway, SR 518 improvements, and the South Link Project on 28th Ave. S., funded through a local parking tax. It establishes rules for how parking tax revenues are divided among projects and outlines corrective actions if actual revenues fall short of forecasts.

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.

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.
