Port of Seattle presentation outlining the Sustainable Airport Master Plan (SAMP) long-term vision with concurrent strategies to serve market demand. Shows current projects for 46.9M passengers, near-term projects targeting 56M passengers by 2027, and long-term vision for demand beyond 2027 including additional planning and environmental review requirements.

On May 30, 2018, the Port of Seattle held its first public open house for the Sustainable Airport Master Plan (SAMP), drawing 147 attendees who discussed Sea-Tac Airport's projected growth to 56 million annual passengers and 480,000 aircraft operations by 2027. Community members raised concerns about noise, pollution, and the disproportionate impact on nearby low-income and minority communities, while Port officials explained limitations on controlling flight schedules and discussed noise mitigation efforts. The meeting notes document questions and answers covering topics such as cargo forecasts, flight pattern changes, the airport's physical footprint, and the possibility of distributing air traffic among other regional airports.

The Highline Forum held a public meeting on May 23, 2018, hosted by the Port of Seattle at Sea-Tac Airport's Central Auditorium, focusing on the theme of Aircraft Altitudes. The two-hour agenda included updates on the Sustainable Airport Master Plan and Federal Issues, as well as a one-hour Aircraft Altitudes Analysis presented by Steve Alverson, Senior Vice President of ESA. The meeting also allowed time for public comments and discussion of emerging issues related to airport noise and flight operations.

This 2018 presentation by Port of Seattle Senior Manager Leslie Stanton outlines air quality initiatives at Sea-Tac Airport, covering the types and sources of air pollution including greenhouse gases and regulated pollutants such as NOx, SOx, and particulate matter. It highlights efforts to reduce emissions through clean vehicle programs, including Sea-Tac's distinction as the first US airport to require green taxis and green TNCs, conversion of CNG buses to electric, and expanded EV charging infrastructure. The presentation also addresses passenger ground transportation planning aimed at improving public transit access and reducing the airport's overall environmental footprint.

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.

This April 2018 Port of Seattle briefing examines traffic congestion challenges at Seattle-Tacoma International Airport (SEA), whose roadway system was originally designed in 1968 for just 5 million annual passengers. It reviews how a major road realignment in 2008 for Light Rail helped reduce gridlock by removing return-to-terminal loop ramps and cutting recirculating vehicle traffic by 40%. The briefing emphasizes that managing landside access at SEA requires a comprehensive, long-term strategic policy to handle the airport's growing transportation demands.
