    Seattle Eight Departure (SEA8.SEA) — Standard Instrument Departure Chart

    The Seattle Eight Departure (SEA8.SEA) is a standard instrument departure procedure for Seattle-Tacoma International Airport, outlining specific climb headings and routes for each runway to guide aircraft safely after takeoff. A notable noise-abatement provision requires large turbine-powered aircraft departing runways 34L, 34C, and 34R between 10 PM and 6 AM local time to be vectored over Puget Sound before proceeding on course. The procedure requires radar and assigns top altitude by ATC, with special minimum climb gradients applicable to runways 16R and 16L.

    Port & community provisions of the Infrastructure Investment & Jobs Act (IIJA)

    This January 2022 briefing by Port of Seattle staff outlines how the federal Infrastructure Investment and Jobs Act (IIJA), signed by President Biden in November 2021, allocates $1.2 trillion across transportation and infrastructure priorities. Of particular relevance to the Port of Seattle, the law includes $20 billion for airports, $5 billion for FAA facilities and equipment, and $5.225 billion for seaports, alongside billions more in competitive grant programs that ports can apply for. The briefing was presented to the Highline Forum, a community body focused on issues related to Sea-Tac Airport and surrounding neighborhoods.

    International Arrivals Facility (IAF)

    Seattle-Tacoma International Airport's new International Arrivals Facility (IAF), presented in January 2022, is a major expansion that increases the airport's international capable gates from 12 to 20 and replaces the old 87,000 sq. ft. facility with a spacious 450,000 sq. ft. building. The project also expanded baggage handling from 4 to 7 carousels using a 'Bags First' system, and supported over 10,000 construction jobs.

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.
