This May 2018 draft report by ESA analyzes changes in aircraft arrival altitudes at Seattle-Tacoma International Airport across 2013, 2015, and 2017, examining how those changes relate to noise exposure for surrounding communities. Key findings from earlier meetings indicate that while overall arrival numbers increased and traffic flow direction remained stable, there was a notable shift in runway use from center runways to right and left runways, along with changes in the mix of narrow-body and wide-body aircraft types serving the airport.

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.

The Des Moines Aviation Advisory Committee met on May 14, 2018 to discuss several Sea-Tac Airport-related issues, including a recommendation to send a letter to the FAA urging the hiring of Community Engagement employees, an update on the city's consultant search ahead of the Port's Strategic Airport Master Plan (SAMP) scoping process, and a review of a draft framework letter focused on improving community engagement throughout the environmental impact process. The committee also discussed Hush House noise-reduction technology potentially coming to Sea-Tac Airport and noted upcoming events including a Port-hosted Open House on the Airport Master Plan and a Noise 101 workshop for START members.

A May 2018 Port of Seattle Commission briefing assessed the financial impact of the Sustainable Airport Master Plan (SAMP) on Sea-Tac Airport, finding that adding SAMP projects could push airline cost-per-enplaned-passenger (CPE) to an infeasible $36 by 2027. To keep costs within an acceptable range of $25–$30, the Port identified the need to increase non-aeronautical revenues, control operating and maintenance expenses, and reduce projected capital spending. The briefing concluded that SAMP is financially achievable, but only with vigilant cost management.

This document outlines the Seattle-Tacoma International Airport Master Plan (SAMP) near-term capital improvement projects spanning 2017 through 2027, totaling approximately $4.47 billion in planned investments. Major project groups include a new North Terminal complex, landside busway improvements, airfield upgrades, and temporary gate expansions, with peak spending projected around 2024–2026. The plan reflects Sea-Tac's long-range strategy to expand capacity, modernize infrastructure, and accommodate growing passenger and cargo demand.

The Port of Seattle presented a Sustainable Airport Master Plan (SAMP) Update to the International Boulevard Business Operators and Transportation Review Committee on May 4, 2018, outlining the airport's long-term vision and near-term projects. The update covered planning progress, including completed steps such as FAA-approved market demand analysis and two rounds of public open houses, with a third open house planned for May 30. Three conceptual alternatives for a second terminal and roadway configuration were introduced, all requiring further study to assess feasibility, cost, and operational efficiency.
