A 2022 Washington State report recommends a three-part strategy to address the region's projected 27 million annual passenger shortfall by 2050: expanding capacity at existing airports like Paine Field and Sea-Tac, and developing a new greenfield airport in Pierce or Thurston County. Sea-Tac is expected to remain the region's primary hub, optimizing capacity for passengers and freight through the 2030s under its Sustainable Airport Master Plan. The report also highlights the need to address harmful emissions and noise as part of an 'Airport of the Future' approach.

The Commercial Aviation Coordinating Commission (CACC) held an online public engagement process in August–September 2022 to gather Washington state residents' input on potential new airport sites. Nearly 20,000 users participated, and majorities opposed all ten proposed 'greenfield' locations, citing concerns about environmental impacts, noise, farmland loss, and traffic. The most common feedback at virtual public meetings was opposition to the East King County site, with many participants also raising concerns about proximity to Sea-Tac Airport.

This document outlines regional policies for High Occupancy Vehicle (HOV) lanes in the central Puget Sound region, covering rules for lane operation, enforcement, and public education. It establishes that HOV lanes should be reserved 24 hours a day, seven days a week for buses, carpools, and vanpools, and calls for increased fines for violations and better use of technology to improve compliance. The policies were developed by the Regional HOV Policy Advisory Committee in 1998-1999 and are intended to reduce traffic volumes, lower vehicle emissions, and improve overall transportation efficiency.

Destination 2030 is a long-term regional transportation plan for the greater Seattle area that outlines both short-term investments (prior to 2010) and longer-term improvements through 2030, focusing on roadway expansions, HOV lane completions, freight network connections, and reduced traffic congestion. The plan prioritizes safety, maintenance, and optimization of existing roads before pursuing new capacity projects, while also emphasizing travel alternatives and pedestrian and bicycle improvements. Fund allocations are guided by project readiness, regional need, and consistency with local growth management policies.

This is a Washington State Joint Aquatic Resources Permit Application (JARPA) submitted by the Washington State Department of Transportation (WSDOT) for the SR 509 Stage 2 Project, which involves constructing a new expressway between 24th Avenue South and South 188th Street in the cities of Burien, Des Moines, and SeaTac, King County. The project corridor runs through publicly owned land and spans multiple sections of townships near Sea-Tac Airport. The application was received on March 24, 2022, and covers permits related to aquatic resources affected by the highway construction.
