In January 2019, the City of Burien, Washington considered Resolution No. 406, calling for action on growth and safety concerns at Seattle-Tacoma International Airport. The resolution highlights the negative health, environmental, and economic impacts on Burien residents due to the city's proximity to the airport, and notes that even with a planned $10 billion expansion under the Sustainable Airport Master Plan, the airport would still lack sufficient capacity within a decade. The city supported ongoing state and federal studies into regional aviation capacity and the impacts of airport operations on surrounding communities.

This 2019 Aviation Committee document outlines Sea-Tac Airport's Ground Transportation Framework, detailing the guiding principles, goals, and strategies for managing how passengers and vehicles move through the airport. Key goals include reducing environmental impact (50% scope 3 emissions reduction), cutting private vehicle pick-up and drop-off to 30% of trips, and achieving a 15-minute tower-to-curb travel time. Strategies span infrastructure planning (SAMP), access policy (GTAP), day-to-day operations, and taxi/TNC contracts, with Port policies providing overarching guidance across all areas.

In this Winter 2019 edition of Des Moines City Currents, Mayor Matt Pina outlines the city's strong opposition to Sea-Tac Airport's expansion plans, arguing that rapid growth between 2012 and 2017—including surging passenger numbers, aircraft operations, and air cargo—has already caused disproportionate noise, health, and environmental impacts on surrounding communities. The city formally called on the Port of Seattle to conduct a comprehensive environmental review under Washington State's SEPA laws before approving any further capacity-building projects, and specifically demanded that issues such as nighttime flight noise, fuel dumping, ultra-fine particle emissions, and Third Runway usage be included in the scoping process. Members of the city's Aviation Advisory Committee also voiced concerns about the health toll on residents, outdated federal standards, and the need for alternatives such as a second regional airport.

A December 2018 email chain forwarded by community advocate Debi Wagner to Burien city officials shares research links connecting aviation emissions and aircraft noise to serious public health concerns, including ultrafine particle pollution, cognitive impairment, cardiovascular disease, and cancer. The email references studies such as the University of Washington's MOV-UP study confirming ground-level ultrafine particle impacts near Sea-Tac Airport, as well as EPA Region X recommendations for resources on airport air quality and public health. The correspondence highlights growing community and regulatory interest in understanding the health effects of airport operations on neighborhoods surrounding Sea-Tac.

This January 2019 Port of Seattle Commission briefing outlines the agency's local and regional government policy priorities for 2019, covering areas such as climate and sustainability, regional transportation, workforce development, maritime projects, and aviation. On the airport side, key priorities include advancing the Sustainable Airport Master Plan (SAMP) near-term projects to address regional demand, and engaging surrounding South King County communities through forums like the Sea-Tac Stakeholder Advisory Round Table (StART). The document reflects the Port's broader effort to balance airport growth with community concerns, economic opportunity, and environmental responsibility.

In December 2018, the Port of Seattle Commission reviewed its draft state legislative priorities for the 2019 session, covering topics such as clean fuels standards, workforce development, and transportation access to Sea-Tac Airport. The agenda sought state funding for transportation infrastructure improvements, including potential upgrades to State Route 518 and the Puget Sound Gateway Program, to address growing demand linked to airport expansion. Additional priorities included supporting small and minority-owned businesses, maritime innovation, and land use policies affecting port competitiveness.

The Port of Seattle presented its 2019 State Legislative Agenda for final Commission adoption on December 11, 2018, outlining three priority areas: workforce development in maritime and industrial sectors, transportation access improvements to Sea-Tac Airport (including upgrades to State Route 518 and the Puget Sound Gateway program), and a Clean Fuels Standard to reduce emissions from port operations. The agenda reflects feedback gathered from subject matter experts, commissioners, and executive staff following an initial November 27, 2018 presentation. The overarching focus of the legislative priorities is reducing emissions, growing jobs, and increasing opportunities in the region.

This FAA Airport Capacity Profile for Seattle-Tacoma International Airport (SEA) outlines the airport's runway configurations and hourly flight capacity under different weather conditions, including visual, marginal, and instrument scenarios. The document describes recent improvements such as Time-Based Flow Management and Reduced Diagonal Spacing, as well as future enhancements like improved runway delivery accuracy and Wake Recategorization Phase 2, all aimed at increasing the number of aircraft the airport can handle safely. Data covering December 2015 through December 2016 shows that visual conditions prevail 57% of the year, with instrument conditions occurring 25% of the time.

The Port of Seattle requested Commission approval to reimburse airport tenant SP-LW LLC (Sub Pop-Li'l Woody's) up to $360,095.72 for design costs after it was discovered that a required grease waste line could not be installed at their originally awarded Concourse C restaurant space (CC-06) due to building code constraints. As a resolution, the Port proposed moving the tenant to a comparable space in the North Satellite (NS-23) and amending their lease accordingly, with no changes to concession fees. The situation also prompted the Port to establish new planning protocols to verify utility infrastructure viability before awarding future food and beverage spaces.
