    Mobile ObserVations of Ultrafine Particles (MOV-UP) advisory

    The MOV-UP (Mobile ObserVations of Ultrafine Particles) study, presented at the Highline Forum in January 2019, was commissioned under a Washington State proviso to investigate air quality impacts from Sea-Tac Airport traffic. Researchers from the University of Washington measured ultrafine particle (UFP) concentrations in communities surrounding the airport, aiming to distinguish aircraft-related pollution from other sources. A final study report was due to local governments and the community by December 1, 2019.

    Regional Aviation Baseline Study

    A November 2018 presentation by the Puget Sound Regional Council examined regional aviation needs against a backdrop of rapid growth in the central Puget Sound area, where the population rose from 3.7 million to 4.1 million people between 2010 and 2018. Over the same period, the region's job count grew from 1.9 million to 2.3 million, reflecting a strong and expanding economy. The study established a baseline for understanding how this growth affects aviation demand and, by extension, noise and capacity pressures at airports such as Sea-Tac.

    Regional Aviation Baseline Study

    A November 2018 presentation by the Puget Sound Regional Council examined the growing demand for aviation in the central Puget Sound region, driven by rapid population growth from 3.7 million to 4.1 million people and job growth from 1.9 million to 2.3 million jobs between 2010 and 2018. The Regional Aviation Baseline Study was presented to the Highline Forum to establish a foundation for understanding how the region's booming economy and population are shaping future airport capacity needs. The study provides context for ongoing policy discussions around Sea-Tac Airport and regional aviation planning.

    Puget Sound Gateway Program SR 509 Completion Project: Highline Forum update

    The Puget Sound Gateway Program, presented at a Highline Forum in September 2018, outlines two highway completion projects—SR 509 in King County and SR 167 in Pierce County—designed to improve freight movement between the ports of Seattle and Tacoma and key distribution centers. Among its key benefits, the program includes a new south access point to Sea-Tac Airport and aims to reduce congestion on local roads surrounding the airport. Funding for the program combines state, local, federal, and toll revenue sources, with electronic tolling on all new lanes expected to begin as early as 2025.

    Final Highline Forum agenda: SR 509 & SR 518 projects

    The Highline Forum held its September 26, 2018 meeting in Normandy Park, focusing on SR 509 and SR 518 transportation projects alongside Seattle-Tacoma International Airport-related topics. The agenda included updates on the Sustainable Airport Master Plan, the StART (Sea-Tac Airport Roundtable) community engagement program, and airport noise programs, presented by Port of Seattle officials. Infrastructure improvements in Normandy Park and a WSDOT briefing on regional highway gateway projects were also on the agenda.

    NTP environmental review schedule

    The Port of Seattle outlined an environmental review schedule for the NTP (Noise Trajectory Program) at Seattle-Tacoma International Airport, spanning 2018 to 2019. Key steps included public scoping meetings held in September 2018 in cities such as Des Moines, Seattle, Federal Way, and Sea-Tac, followed by environmental analysis and the release of draft and final NEPA/SEPA documents through late 2019. Community members could submit scoping comments by September 28, 2018, via the project website, email, mail, or in person at scoping meetings.

    Aviation Noise Working Group facilitator’s meeting summary

    The StART Aviation Noise Working Group held its first meeting on August 16, 2018, bringing together community stakeholders, airlines, the FAA, and Port of Seattle representatives to discuss strategies for reducing aircraft noise around Sea-Tac Airport. The group reviewed four potential near-term approaches—including a Runway Use Agreement, a Nighttime Voluntary Curfew, Glide Slope and Optimized Profile Descent Analysis, and an Airfield Noise/Reverse Thrust Assessment—all of which were deemed worthy of further exploration. The group agreed to meet monthly and outlined next steps, including gathering night-operations data and drafting a formal work program to guide future action.
