In September 2018, the FAA submitted the National Plan of Integrated Airport Systems (NPIAS) 2019–2023 report to Congress, identifying 3,340 airports important to national air transportation and estimating $32.5 billion in eligible infrastructure development needs over that five-year period. The report, required by federal law every two years, covers topics including safety, capacity, environmental conditions, runway pavement condition, and financial performance of the national airport system. While this document focuses on broad national airport planning and funding, it does not specifically address noise policy at Seattle-Tacoma International Airport.

The Northwest Mountain Regional Airport Plan (RAP) 2012 outlines the FAA's priorities for airport system development across the Northwest Mountain Region, covering safety improvements, runway upgrades, and investment strategies for 136 focus airports. The plan addresses key initiatives such as runway safety areas, wildlife hazard assessments, and preparation for NextGen technologies, with funding decisions guided by a regional Board of Directors overseeing the Airport Improvement Program. Note that this document covers regional airport planning broadly and does not specifically address Sea-Tac Airport noise policy.

This document is an appendix from Washington State's 2009 Aviation System Plan, listing detailed information about airports across the state. It catalogs each airport by site number, name, city, and service level classifications under both federal (NPIAS) and state systems, covering facilities ranging from major commercial airports like Seattle's Boeing Field to small rural seaplane bases. The table includes nearly 100 airports of varying types and service levels throughout Washington State.

The Washington Aviation System Plan identifies four Special Emphasis Regions in the state, with the Puget Sound region — encompassing King, Snohomish, Pierce, and Kitsap Counties — standing out as the busiest aviation area. The region is home to Seattle-Tacoma International Airport, the state's primary commercial airport, along with 27 other public-use airports serving commercial, general aviation, and seaplane operations. As of 2005, the Puget Sound region housed approximately 55 percent of Washington's total population, driving significant demand for air service and making adequate airport capacity a key economic priority.
