    Flight Corridor Safety Program: Tree Obstruction Analysis Overview and Removal Summary

    This draft document, updated October 2019, summarizes an obstruction removal study conducted near Seattle-Tacoma International Airport, identifying 174 trees that penetrate or are predicted to penetrate FAA-required airspace surfaces. The trees are distributed across multiple property owners, with WSDOT holding the largest share (102), followed by Highline School District (26), private owners (19), SeaTac (21), and the Port (6). The study, which involved LIDAR scanning, FAA-approved analysis, and field verification, classifies the obstructions as topped, existing, or potential future penetrations, with conifers making up the vast majority of affected trees.

    Seattle-Tacoma International Airport Flight Corridor Safety Program Implementation Plan

    This October 2019 draft Implementation Plan, prepared by Anchor QEA for the Port of Seattle, outlines a program to identify and remove trees and other obstructions from the flight corridors around Seattle-Tacoma International Airport. The plan covers properties owned by the Port, public agencies (including WSDOT and the cities of SeaTac and Des Moines), and private landowners in Burien and SeaTac, detailing removal schedules, revegetation strategies, and best management practices. Its primary goal is to improve aviation safety by ensuring that vegetation and structures do not encroach on protected airspace around the airport.

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.
