    The Port of Seattle Commission this week approved the acceleration of sound insulation projects for homes, apartments, condominiums and places of worship in airport communities to be completed in less than half its current schedule. The faster noise reduction benefits near Seattle-Tacoma International Airport will cover projects originally not expected to be complete for another

    Flight Corridor Safety Program 2019 real property – Introduction of Resolution 3771

    The Port of Seattle Commission is introducing Resolution 3771 to support the Flight Corridor Safety Program 2019, which involves removing trees near Seattle-Tacoma International Airport that obstruct FAA-designated flight approach and departure paths. The program seeks to acquire permanent easements on private properties to prevent future obstructions and ensure ongoing compliance with FAA regulations and the airport's operating certificate. If voluntary negotiations with property owners fail, the Port is authorized to pursue condemnation as a last resort to secure the necessary property rights.

    Advisory circular: Hazardous wildlife attractants on or near airports

    This FAA Advisory Circular (AC 150/5200-33C), issued February 21, 2020, provides guidance on land uses and development projects near public-use airports that may attract hazardous wildlife such as birds, mammals, and reptiles, which pose serious safety and economic risks to aircraft. It outlines recommended practices for airport operators, land-use planners, and federally funded airport projects to assess and mitigate wildlife hazards, though compliance is voluntary except for airports holding operating certificates under 14 CFR Part 139 or receiving federal grant funding. The document updates and replaces the previous 2007 version of the same circular.

    Model-extrapolated estimates of airborne lead concentrations at U.S. airports

    This EPA technical report estimates airborne lead concentrations near U.S. airports caused by piston-engine aircraft burning leaded aviation gasoline (avgas). Using air quality modeling and extrapolation methods, the study identifies airports where lead levels may exceed national air quality standards, particularly in areas close to aircraft run-up zones. While not specific to Sea-Tac Airport, the findings are relevant to understanding aviation-related air quality impacts at airports nationwide.

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.
