WASP Background:

The Washington State Department of Transportation is updating the Washington Aviation System Plan (WASP). The primary purposes of the WASP update are to:

  • Study the performance and interaction of Washington's entire aviation system.
  • Understand the contributions of individual airports to the system as a whole.

The study involves examining aviation user requirements, current airport usage levels and based aircraft and capacity to meet current and future demand.

WASP Priorities:

Build upon previous efforts and recommendations:

  • 2009 Long-Term Air Transportation Study
  • 2012 Aviation Economic Impact Study
  • 2014 Airport Investment Study
  • 2015 Airport Investment Solutions Study

Identity issues and evaluate impacts to determine needed airport and system improvements. Engage with the community and seek input. Prioritize development and make recommendations.

Stakeholder Groups:

  • Advisory Committee
  • Interested Parties
  • Multimodal Working Group
  • Emerging Issues Working Groups
