    Comment letter on the Washington Aviation System Plan (WASP) draft report

    A letter from the City of Burien to WSDOT criticizes the 2017 Washington Aviation System Plan (WASP) for failing to address the health and environmental impacts of growing aircraft noise and air pollution on communities near Seattle-Tacoma International Airport. The letter argues that the plan focuses too narrowly on aviation and economic development while ignoring issues such as hearing loss, poor student performance, sleep disruption, and asthma affecting lower-income and ethnically diverse neighborhoods. The author calls on WSDOT and regional governments to explore alternative airport locations to relieve the disproportionate burden placed on South King County communities.

    CACC Frequently Asked Questions

    This document compiles frequently asked questions about Washington State's Commercial Aviation Coordinating Commission (CACC), which is studying potential locations for a new commercial airport in the region. It covers how the Commission was formed, what studies have been used to evaluate possible sites, and how environmental concerns—such as impacts on aquifers, the Nisqually River watershed, and tribal treaty rights—factor into site selection. The CACC can only recommend a site to the State Legislature, which retains final authority over any next steps.

    Commercial Aviation Coordinating Commission report to legislative transportation committees

    The Washington State Commercial Aviation Coordinating Commission's 2022 report to the Legislature identifies six existing airports — including Paine Field, Bremerton National, and Tacoma Narrows — as candidates for expanded aviation capacity, while also exploring potential greenfield sites for a new airport. The report summarizes public input showing that a majority of respondents support building new aviation capacity despite environmental costs, and outlines the Commission's guiding principles of public benefit, economic feasibility, environmental responsibility, and social equity. The Commission's final recommendations are expected by February 15, 2023.

    Washington Aviation System Plan (WASP): Executive Summary

    The Washington Aviation System Plan (WASP), completed in July 2017 by the Washington State Department of Transportation (WSDOT), is a statewide assessment of Washington's public-use airports covering both commercial and general aviation facilities. The plan evaluates how individual airports perform and interact as a system, identifies needed improvements, and develops policy recommendations to support communities, economic activity, and emergency services across the state. Funding was provided by the Federal Aviation Administration (FAA), and the plan builds on the earlier 2009 Long-term Air Transportation Study (LATS).

    Washington Aviation System Plan Update: WASP Process and Schedule Flyer

    The Washington State Department of Transportation (WSDOT) launched an update to the Washington Aviation System Plan (WASP) in July 2015, aimed at studying the performance of Washington's entire aviation system and identifying needed airport improvements. The plan involves analyzing aviation user requirements, airport capacity, and emerging issues such as unmanned aircraft systems, aviation fuels, and airport infrastructure funding challenges. A broad advisory committee representing airports, airlines, government agencies, and aviation associations was assembled to guide the process, which was scheduled for completion by early 2017.
