An airport master plan is a comprehensive study of an airport that describes its short, medium, and long-term sustainable development goals, alternatives, and plans. Master plans are required by the Federal Aviation Administration (FAA) to establish the regulatory framework for our future development, both airside and landside.

Process and timeline

The master plan update process will center around a series of five technical working papers on the following subjects:

  • Inventory and forecasts
  • Capacity analysis and facility requirements
  • Alternatives
  • Environmental documentation
  • Financial improvement plan

Stakeholder input and working group

Stakeholder input is an important part of the planning process. KCIA convened a master plan update airport working group that represents diverse interests. The group's meetings are open to the public. To receive email notifications about the meetings, email a request to Michael Colmant.

Airport users and neighbors will also have opportunities to review project information and provide input at open house meetings and via this website.

King County International Airport is one of the nation’s busiest general aviation airports, and operations are expected to increase by 50 percent over the next two decades to meet growing demand. The master plan’s focus is on ways to best satisfy growing aviation demands within the airport’s existing boundaries while meeting the strictest aviation safety standards.

This document lists the minimum standards as well as basic rules and regulations for all providers of aeronautical services at King County International Airport.


As part of its environmental review for the master plan (see above), King County International Airport prepared an approved environmental impact statement under the Washington State Environmental Policy Act, and an environmental assessment under the National Environmental Policy Act. The EIS identifies any impacts the airport might have on its immediate environment, in light of the development guidelines laid out in the master plan.

Title 15 of the King County Code pertains to the governing of King County International Airport/Boeing Field.
