King County International Airport is currently one of the nation’s busiest general aviation airports, and operations are expected to increase by 50% over the next two decades to meet growing demand. The Master Plan’s focus is on ways to best satisfy the growing aviation demands, within the airport’s existing boundaries, while meeting the strictest aviation safety standards.
As part of its environmental review for the Master Plan (see above), King County International Airport has prepared an approved Environmental Impact Statement (EIS) under the Washington State Environmental Policy Act (SEPA), and an Environmental Assessment (EA) 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.
