The Federal Aviation Administration (FAA) has issued a Final Environmental Assessment (EA) and a Finding of No Significant Impact/Record of Decision (FONSI/ROD) for the Port of Seattle’s proposed Sustainable Airport Master Plan Near-Term Projects (NTPs) at Seattle-Tacoma International Airport (SEA).
The FAA concluded that the projects align with existing environmental policies under the National Environmental Policy Act of 1969 and will not significantly affect the quality of the human environment.
The Sustainable Airport Master Plan (SAMP) provides a framework for future development at SEA, addressing passenger terminal and cargo capacity, aircraft delays, fuel storage, and compliance with FAA airfield standards. The 31 NTPs aim to improve airport efficiency, safety, access, and support facilities for airlines and passengers.
The FAA identified 17 findings for the Port to address during design, construction, and operation of the projects. Most of these are standard practices at SEA, with one new requirement to improve surface transportation at 26 intersections. This represents an estimated 40 million USD investment intended to benefit local communities.
SEA’s expansion plans focus on developments within the existing airport footprint to meet current and anticipated demand, maintaining operational efficiency and accessibility.
The next stage for the 31 NTPs is a State Environmental Policy Act (SEPA) review led by the Port, which will include public input.
