This 2019 Working Paper, prepared by WSP for the Puget Sound Regional Council, examines airport and aviation activity across the greater Seattle-Tacoma region as part of a Regional Aviation Baseline Study. It covers commercial aviation, general aviation, and air cargo trends and forecasts, along with multimodal access and economic context for the region's airports. The study establishes baseline data and metrics to inform future regional aviation planning and policy decisions.

The Regional Aviation Baseline Study, published by the Puget Sound Regional Council in June 2019, examines the roles and interactions of 29 airports across the central Puget Sound region, including Sea-Tac as the area's primary large hub. The study aims to provide a regional perspective on how aviation activities affect communities and the broader economy, while gathering stakeholder input on aviation and airspace constraints. Its findings are intended to identify future aviation needs and lay the groundwork for long-term regional planning.

The Regional Aviation Baseline Study, published June 27, 2019 by the Puget Sound Regional Council, examines the roles and interactions of 29 airports across the central Puget Sound region, including Sea-Tac as the area's sole large hub. The study aims to gather stakeholder input on aviation and airspace constraints, assess how airport activities affect surrounding communities and the broader economy, and lay the groundwork for future regional aviation planning.

This document is a presentation from the first Technical Workshop of the Regional Aviation Baseline Study, held on June 11, 2019. It covers an overview of airport and aviation activities in the region, including data collection, economic context, trends and forecasts, and multimodal transportation connections. The workshop also addressed goal areas, objectives, and performance metrics to inform future regional aviation policy.

The Puget Sound Regional Council's 2018 Annual Report highlights regional transportation milestones, including the opening of the new Paine Field Passenger Terminal in Snohomish County — a project described as decades in the making. The report features a message from PSRC President and Snohomish County Executive Dave Somers and Executive Director Josh Brown, celebrating the terminal as a major economic and travel resource for the greater Puget Sound region. Note: this document focuses on regional planning and infrastructure progress and does not directly address Sea-Tac Airport noise policy.

The Puget Sound Regional Council launched a two-year Regional Aviation Baseline Study, funded by a $1.6 million FAA grant, to assess the aviation system across King, Pierce, Snohomish, and Kitsap counties. The study examined existing airport roles, economic contributions, airspace capacity, and community impacts to build a technical foundation for future regional aviation planning decisions. Conducted in phases from 2019 to 2020, the study included stakeholder engagement, public meetings, and a final report outlining strategies for accommodating future aviation demand in the central Puget Sound region.

A January 2019 report to the Puget Sound Regional Council examines aviation demand in the Central Puget Sound region, where the population grew from 3.7 million to 4.1 million people and jobs increased from 1.9 million to 2.3 million between 2010 and 2018. Over roughly the same period, passenger traffic at Seattle-Tacoma International Airport rose 43% to 46.9 million passengers, while aircraft operations increased 32% to 416,000 annually. The study establishes a baseline for understanding how this rapid regional growth is driving increased aviation activity, with implications for noise and capacity planning.
