    Section 13: Socio-Economics — Study of the Current and Ongoing Effects of the Operation of the Seattle-Tacoma International Airport

    This 2020 report examines the socio-economic conditions in six south King County cities near Seattle-Tacoma International Airport, including Burien, Des Moines, Federal Way, Normandy Park, SeaTac, and Tukwila. It analyzes demographic trends such as population growth, age distribution, and ethnic profiles from 1997 to 2018, finding that most study area cities grew more slowly than King County overall, with Burien being a notable exception largely due to a 2010 annexation. The report is part of a broader study assessing how airport operations affect surrounding communities across indicators including income, housing, education, employment, and municipal tax revenues.

    Airport basics | Port Of Seattle

    Seattle-Tacoma International Airport handled 49.8 million passengers and 438,391 aircraft operations in 2018, ranking 8th in the U.S. by passenger volume. A noise compatibility study forecasted total annual aircraft operations to grow from approximately 301,870 in 2009 to 399,200 by 2021, driven by increases in both domestic and international air carrier activity. The airport operates three category IIIb certified runways and is dominated by Alaska Airlines, which carries over 50% of its passengers.

    Sea-Tac Airport: passenger and air cargo activity

    Sea-Tac Airport saw record activity between 2014 and 2017, with over 46 million passengers and 425,895 metric tons of cargo passing through in 2017 alone. Passenger growth is slowing — dropping from a 13% year-over-year increase in 2015 to just 2.6% in 2017 — while air cargo, driven largely by domestic freight, surged 16% compared to the prior year. Summer months remain the busiest for passengers, and air mail volumes have shown a steady annual increase throughout the period.

    Sea-Tac Airspace Update Study: Comparison of 1988 Airspace Update Study, 1992 Terminal Development Plan, and the 1991 Enhancement Plan

    This 1992 study compares three planning reports on Sea-Tac Airport's future capacity and delays: the 1988 Airspace Update Study, the 1992 Terminal Development Plan, and the 1991 Enhancement Plan. The reports differ significantly in their passenger and flight operation projections for the year 2000, and show striking discrepancies in delay estimates — with the Enhancement Plan projecting delay hours more than five times higher than the Airspace Update Study. The document also outlines proposed solutions to reduce delays, including new runway construction, airspace conflict resolution with nearby Boeing Field, and improved approach procedures.

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.
