Help us plan for the future of King County International Airport

King County International Airport (KCIA) is undertaking two important studies to plan for the future of the airport: Vision 2045 Airport Plan and the Part 150 Study. The County owns and operates KCIA, a public-use airport that is part of the National Plan of Integrated Airport Systems (NPIAS). Both King County and the Federal Aviation Administration (FAA) have authority over different parts of the airport’s operations, management, and future development.

The Vision 2045 Airport Plan will evaluate how KCIA can evolve and adapt to meet future aviation needs and become a world-class airport. The Vision 2045 Airport Plan will identify projects KCIA would implement to continue to operate safely and efficiently while meeting changing aviation demand. Vision 2045 will follow long-range facility planning guidance from the FAA and will also account for potential environmental and socioeconomic impacts.

The Part 150 Study will help the airport develop noise exposure maps and evaluate noise compatibility programs. The Part 150 Study is a voluntary Federal Aviation Administration (FAA) process that King County International Airport (KCIA) is undertaking to develop noise exposure maps and evaluate noise compatibility programs associated with aircraft operations.

Centering community in the Vision 2045 Airport Plan and the Part 150 Study

KCIA is located near many residential neighborhoods including Allentown, Beacon Hill, Georgetown, Glendale, Rainer Beach, and South Park. Public input is critical to the successful outcome of Vision 2045 and the Part 150 Study. We will ask about important issues like safety, noise, environmental impacts, and use of the airport. Both technical information and community input will inform the plan. KCIA will invite input through committees, surveys, and in-person and online events.

A Project Advisory Committee (PAC) will provide local perspective and technical input for the Vision 2045 Airport Plan and Part 150 Study. The PAC represents city and neighborhood councils, businesses, airport tenants, labor unions, and Federal Aviation Administration and KCIA staff.

KCIA will also use information from the Part 150 Study and the Airport Strategic Plan to inform the Vision 2045 Airport Plan. The Airport Strategic Plan is an opportunity to review KCIA’s role in the regional economy and will have a separate community engagement process.
