Commercial Aviation Coordinating Commission

The Commercial Aviation Coordinating Commission was created by the Legislature (pdf 76 kb) and tasked WSDOT Aviation to provide staff support for coordinating and administering the commission and technical assistance as requested by commission members.

CACC is required to recommend, by sixty percent majority vote, a single preferred location by February 15, 2023. The commission shall project a timeline for the development of an additional commercial aviation facility (single preferred location) that is completed and functional by 2040 and must make recommendations on future Washington state long-range commercial facility needs. It should be noted the original schedule for these recommendations was extended by the Legislature due to the disruption in workflow and communications with the public, and the uncertainty with return to normal aviation activity caused by the pandemic.

WSDOT Aviation is responsible for the administration of the commission’s work while providing technical support to the commission members.

Communication to the public and stakeholders will be crucial for CACC. The communication plan will provide the following:

  • A logical and factual framework for understanding the issues that must be addressed by the CACC and for understanding how the decisions will be made.
  • Meaningful ways for people who want to be included and involved in the deliberations of the CACC.
  • Assure that major stakeholders, such as local governments, the aviation industry, airports, and regional planning agencies have timely information to assure meaningful input
