This 2017 technical memorandum, prepared by Leigh Fisher for the Port of Seattle, outlines development alternatives for Seattle-Tacoma International Airport as part of a Sustainable Airport Master Plan. It covers proposed changes to the airfield, passenger terminals, ground access, parking, air cargo facilities, and general aviation. The document evaluates options such as runway relocations, new taxiway configurations, and terminal expansions to address capacity, safety compliance, and long-term growth needs.

The Highline Forum held its September 27, 2017 meeting at the Des Moines Beach Park Dining Hall, focusing on the theme of air quality in communities surrounding Seattle-Tacoma International Airport. The agenda featured presentations from Port of Seattle Aviation Managing Director Lance Lyttle on airport community engagement, and a regional air quality briefing from the Puget Sound Clean Air Agency. The forum also included an update from the City of Des Moines, finalization of operating procedures, and discussion of topics for the next scheduled meeting.

In September 2017, Des Moines, WA resident Steve Edmiston sent a certified letter demanding that the Port of Seattle and the FAA stop increased flight operations over his historic Woodmont neighborhood, arguing that no avigation easement had ever been granted over his property. He cited a dramatic rise in aircraft noise, vibrations, fumes, and nighttime flights linked to expanded use of Sea-Tac's third runway and new navigation procedures, noting that commercial operations at the airport had nearly doubled since 2003. The letter also included a formal public records request for documents related to flight procedure changes made after February 14, 2012, and outlined legal grounds under which affected homeowners may still seek damages despite general noise liability limitations.

This 2017 presentation by Port of Seattle Sustainability Manager Leslie Stanton outlines air quality initiatives at Seattle-Tacoma International Airport, covering pollution sources, reduction programs, and the Port's environmental goals. It highlights that while the Port has limited regulatory authority, it is pursuing innovative strategies to cut emissions, including efforts around ultrafine particulates and climate-related particulate matter reductions. The presentation also reviews existing air quality studies and identifies next steps for improving air quality in and around Sea-Tac Airport.

This July 2017 presentation by Port of Seattle Sustainability Manager Leslie Stanton outlines air quality initiatives at Seattle-Tacoma International Airport, covering the types and sources of air pollution, the Port's environmental goals, and efforts to reduce emissions. It highlights that while the Port has limited regulatory authority, it is pursuing innovative programs with multiple benefits and tracking emerging science around ultrafine particulates and particulate matter reductions tied to climate strategies. The document serves as an overview of Sea-Tac's approach to managing and improving local air quality amid growing aviation activity.

The Highline Forum held on July 26, 2017, at SeaTac City Hall brought together community stakeholders, city officials, and representatives from WSDOT and the Port of Seattle to discuss key regional topics including the SR 509 Puget Sound Gateway Program, aircraft altitude concerns, and air quality initiatives near Sea-Tac Airport. Presentations were delivered by Port of Seattle staff covering noise programs and environmental initiatives, alongside updates on SeaTac's economic development. The meeting provided a public forum for emerging issues and planning for future discussions on airport-related impacts to surrounding communities.

In a July 2017 letter, Seattle-Tacoma International Airport's Managing Director Lance Lyttle acknowledged concerns from the City of Des Moines regarding the airport's Concourse D Hardstand Holdroom project, confirming that no additional gates would be added until the Sustainable Airport Master Plan (SAMP) environmental review was completed. Following this, the cities of Burien, Des Moines, Normandy Park, and SeaTac entered into an Interlocal Agreement in March 2018 to jointly hire the consulting firm Lockridge Grindal Nauen PLLP for $175,000 to conduct an environmental review of the SAMP. Costs were shared among the four cities based on a per-capita funding rate of approximately $1.50, with Burien covering the largest share at roughly 43%.

The Port of Seattle's 2017–2021 Long Range Plan outlines a five-year rolling strategy to achieve the Port's Century Agenda goals, including adding 100,000 jobs to reach 300,000 total port-related jobs in the region while reducing its environmental footprint. Developed by over 100 Port employees, the plan covers five focus areas — aviation, maritime, economic development, environment, and high-performance organization — and sets specific actions and performance measures for each. The plan is updated and formally adopted by the Commission annually to guide budgeting and operational priorities across all Port divisions.
