Learn more about Vision 2045 Plan and Part 150 Noise Study

Open House on September 25, 2025

King County International Airport-Boeing Field (KCIA) invites community members and airport tenants to attend an open house on Thursday, September 25 from 5:30 to 7:30 p.m. to learn about progress on KCIA's Vision 2045 Airport Plan and the Part 150 Study, a noise and land use compatibility study. The open house will be held at the KCIA Flight Service Station, 6526 Ellis Ave. S. in Seattle. Community members can stop by any time to talk with the project teams and share their feedback.

KCIA is undertaking these two important studies to plan for the future of the airport.

  • The Vision 2045 Airport Plan evaluates how KCIA can evolve and adapt to meet future aviation needs over the next 20 years and become a world-class airport. The plan will identify projects KCIA would implement to continue to operate safely and efficiently while meeting changing 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 measures how much airplane noise can be heard from the ground. The study will be used to help the airport develop noise exposure maps and evaluate noise compatibility programs, and make plans for reducing the effects of noise in surrounding neighborhoods.

Registration for the open house is encouraged so that the airport can plan for the number of participants. 

There will be no formal presentation at the open house, which is the fourth in a planned series of six. Free parking is available in the building's parking lot and on nearby streets. A King County Metro bus stop at Ellis Avenue South and South Warsaw Street, across from the Flight Service Station, serves the 124 and 60 routes. To request language interpretation or other accommodations at the open house, please call 206-296-7380 or email KCIACommunityOutreach@kingcounty.gov.

The study team will host additional open houses and engagement opportunities before both studies wrap up in mid-2026. For more information about these two efforts, please visit KCIAPlanning.com.
