    Appendix H Official Noise Exposure Maps

    This document presents the official Noise Exposure Maps (NEMs) for Seattle-Tacoma International Airport (SEA), developed as part of the FAA Part 150 noise study. It includes maps showing 2022 existing noise conditions and projected 2032 future conditions, along with the flight tracks used in the Aviation Environmental Design Tool (AEDT) modeling for both north and south flow operations. The maps illustrate the geographic extent of aircraft noise impacts across surrounding communities, including Seattle, Burien, SeaTac, Tukwila, and Des Moines.

  • Flight Tracking Map of Seattle Area Aircraft and Blue Angels Flight Path Change

    A real-time flight tracking map centered on the Seattle, Washington metropolitan area showing multiple aircraft in flight, including Alaska Airlines flights AS1304, AS934, and AS347; Delta Air Lines flights DL434, DL1517; Korean Air flight KE41; and several general aviation aircraft (N704ZP, N6040P, N1115U, N718TE, N303LK, N93124, N97662, N94061). A popup identifies a vessel named 'RELIANCE' routing USSEA to USPWT, dimensions 76x26 ft, observed approximately one minute prior to the screenshot.

    Highline Forum: Are arrivals lower now than they were a couple of years ago?

    A Highline Forum presentation examining whether aircraft arrival numbers at Seattle-Tacoma International Airport have decreased compared to a few years earlier. The analysis uses one month of arrival flight track data from June 2013, June 2015, and June 2017 across Sea-Tac's three parallel runways (16L/34R, 16C/34C, and 16R/34L). June was chosen as a representative month because it typically features a balanced mix of north and south flow operations, Instrument Landing System (ILS) and visual approaches, and an average volume of aircraft traffic.

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.
