The Port of Seattle is conducting an environmental review of near-term construction projects at Seattle-Tacoma International Airport (SEA) under the FAA's National Environmental Policy Act (NEPA) process, with a public comment period running October–November 2024. Originally built in 1949 to serve half a million passengers per year, SEA now handles over 50 million annually and is projected to reach 67.2 million passengers by 2035 as the Central Puget Sound region's population grows. The Sustainable Airport Master Plan outlines infrastructure improvements needed to accommodate this long-term growth.Open full document
