    Environmental checklist: Seattle-Tacoma International Airport (SEA) Widen Arrivals Drive

    The Port of Seattle filed an environmental checklist in May 2021 for a project to widen Arrivals Drive at Seattle-Tacoma International Airport (SEA) from two lanes to four lanes, aiming to reduce congestion and improve safety for passengers and ground transportation vehicles. Construction was planned to begin in mid-2023 and last approximately 18 months, involving road realignments, updated stormwater drainage, new LED lighting, and utility relocations. The project was designed as a standalone improvement but coordinated with broader airport master plan efforts to accommodate potential future infrastructure expansions at SEA.

    Sustainable Airport Master Plan (SAMP) Near-Term Projects (NTP) environmental review briefing and request for additional funds

    The Port of Seattle requested $3.4 million in additional funding to complete environmental review studies required under federal (NEPA) and state (SEPA) law for planned near-term expansion projects at Sea-Tac Airport. The cost increase was driven by a two-year planning delay, expanded public engagement in multiple languages, additional technical analyses including aircraft noise, air quality, and environmental justice studies, and a decision to produce two separate review documents instead of one combined report. The contract with aviation environmental consulting firm Landrum & Brown brings the total project cost to $6.4 million.

    City of Des Moines response to Port Of Seattle Executive Director Metruck regarding StART Committee

    In September 2019, the City of Des Moines responded to a Port of Seattle apology letter regarding the allocation of $10 million for Sustainable Airport Master Plan (SAMP) design work without prior environmental review or stakeholder notice, which had prompted Des Moines and other nearby cities to temporarily suspend participation in the Sea-Tac Stakeholder Advisory Round Table (StART). The City challenged the Port's claims of meaningful progress on noise reduction measures, requesting specific data on the Late Night Noise Limitation program, changes to nighttime flight schedules, and the status of runway glide slope adjustments. The exchange highlights ongoing tensions between Sea-Tac Airport and surrounding communities over transparency, environmental compliance, and the effectiveness of collaborative noise mitigation efforts.
