Aviation commission recommends two potential options for new aviation capacity: Final recommendation to Legislature due in June 2023

OLYMPIA – After months gathering public feedback and reviewing technical analyses, the state Commercial Aviation Coordinating Commission submitted Phase II recommendations (PDF 974KB) to the Washington State Legislature that include continued study of two options for future aviation capacity.

The two options were submitted on Oct. 15 and include:

  • Growing Paine Field according to its Airport Master Plan (with potential for additional capacity).
    - This assumes Seattle-Tacoma Airport executes its Sustainable Airport Master Plan, and includes a recommendation to assist other airports interested in pursuing regional commercial service (distributed air service supported by emerging technology)
  • Continue to develop a greenfield site option with a two-runway configuration.
    - Pierce County Central, Pierce County East and Thurston County Central were recommended for additional technical analysis and community outreach. A map of the sites (PDF 974KB) is available online.

The demand for aviation in Washington state is growing and will soon exceed the capacity of existing airports. The Phase II recommendations come eight months after the commission  recommended six preliminary airport sites (PDF 369KB) with potential for expansion to meet both short- and long-term aviation needs.

"This is an opportunity for the state to consider how to meet capacity limits while also planning for an airport of the future," said David Fleckenstein, WSDOT Aviation Director and chairman of the commission. "Increasing the use of sustainable aviation fuels could significantly reduce harmful emissions. Emerging aeronautics technology could also reduce noise from airplanes while also providing additional commercial air service options to more airports around the state."

In the coming months, the commission will offer additional opportunities for public input and study additional technical data about each greenfield site still being considered.

The commission is considering environmental effects, economic and technical criteria and public feedback and opinion as it develops recommendations to improve 
Washington's air transportation capacity.

About the Commercial Aviation Coordination Commission

The Commercial Aviation Coordinating Commission was created by the Legislature (PDF 75KB) in 2019 with a charge to provide a recommendation by June 15, 2023, for a single preferred location to meet the forecast demand for commercial passenger service, air cargo and general aviation. After the commission makes its final recommendation, it will be up to the Legislature and potential airport sponsors to act on that recommendation.

The Legislature directed three phases for the commission's work:

  • Phase I: develop a short list of six locations.
  • Phase II: identify two options for meeting aviation demands.
  • Phase III: choose a single preferred location by a 60-percent majority vote.

In December 2020, the commission released its Phase I report (PDF 204 KB), which listed six preliminary airport sites with potential for expansion to meet both short and long-term aviation needs. A February 2022 report (PDF 369KB) provided a final short list of six locations. The October 2022 report (PDF 141KB) details the two options selected. The commission will provide its recommendation for a single preferred location to the Legislature by June 15, 2023.

The commission's 14 voting and 12 nonvoting members include representatives from the aviation industry, the public, airport communities, freight industry, state and local agencies and elected officials. WSDOT provides the commission technical assistance and staff support from its Aviation Division.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
