    SAMP Public Comment Process: Factsheet

    The Port of Seattle is seeking public comments on a proposed environmental review of 31 Near-Term Projects at Seattle-Tacoma International Airport (SEA), designed to improve efficiency, safety, and access as the Puget Sound region prepares for one million additional residents by 2035. The public comment period runs from October 21 through December 5, 2024, with four in-person meetings scheduled across Federal Way, Des Moines, Burien, and SeaTac. Comments can be submitted online, by email at samp@portseattle.org, by mail, or in person, and will be considered by the FAA and Port of Seattle in finalizing the National Environmental Policy Act (NEPA) Environmental Assessment.

The flowchart spans from initial formulation of proposed actions and alternatives through public scoping, draft EA preparation, public comment periods, and concludes with either a Finding of No Significant Impact (FONSI)/Record of Decision (ROD) or preparation of an Environmental Impact Statement (EIS) if significant impacts are found.

    Seattle-Tacoma International Airport Environmental Assessment for the Sustainable Airport Master Plan Near-Term Projects: Chapter 6 — List of Preparers

    This section of the Seattle-Tacoma International Airport Environmental Assessment lists the individuals and organizations responsible for preparing the document, including staff from the FAA, Port of Seattle, and several consulting firms. The team covered a wide range of technical areas, with specialists handling noise analysis, air quality, surface transportation, wetlands, cultural resources, and public engagement. The assessment was produced in October 2024 as a draft under the airport's Sustainable Airport Master Plan for near-term projects.

    Seattle-Tacoma International Airport Environmental Assessment for the SAMP Near-Term Projects: Chapter 5 — Cumulative Impacts

    This section of the Seattle-Tacoma International Airport Environmental Assessment examines cumulative impacts from past, present, and reasonably foreseeable future development projects at and around SEA airport, covering the period from 2017 through 2032. It reviews actions by the Port of Seattle and surrounding cities and agencies — including hotel construction, terminal expansions, and flight procedure changes — to assess how their combined environmental effects, such as noise, emissions, and land use changes, may affect nearby communities. Projects beyond 2032 or those in the long-term vision phase are excluded from detailed analysis due to insufficient specificity.

    Seattle-Tacoma International Airport Environmental Assessment for the SAMP Near-Term Projects: Chapter 4 — Environmental Consequences

    This October 2024 draft Environmental Assessment evaluates the potential environmental impacts of near-term construction and operational projects at Seattle-Tacoma International Airport under three alternatives: No Action, a Proposed Action, and a Hybrid Terminal Option. The analysis covers impacts through 2032 and an out-year of 2037, finding that increases in air quality emissions and effects on biological resources are not considered significant, with mitigation measures proposed for stormwater management and migratory bird nesting. Farmlands and Wild and Scenic Rivers were determined to have no presence in the study area and required no further analysis.

    Chapter 3: Affected Environment — Seattle-Tacoma International Airport Environmental Assessment for the Sustainable Airport Master Plan Near-Term Projects

    This draft Environmental Assessment from October 2024 examines the existing conditions around Seattle-Tacoma International Airport (SEA) as part of the Sustainable Airport Master Plan Near-Term Projects. Using 2022 as the baseline year, it describes SEA's location on approximately 2,800 acres in the City of SeaTac, situated 12 miles south of downtown Seattle and surrounded primarily by residential neighborhoods. The study covers a General Study Area of 3,692 acres to identify where proposed airport development actions could have direct or indirect environmental impacts on nearby communities.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
