    Comparison of Expert Arbitration Panel’s review of noise and demand/system management issues at Sea-Tac Airport in March 1996 and FAA’s record of approval of Sea-Tac’s Part 150 noise compatibility program

    This document compares a 1996 Expert Arbitration Panel's findings on aircraft noise at Seattle-Tacoma International Airport with the FAA's 2013-2018 Part 150 Noise Compatibility Program approval, revealing that many of the same unresolved noise abatement and mitigation issues identified decades ago remain unaddressed today. Communities surrounding Sea-Tac — including Burien, Normandy Park, and Des Moines — continue to experience increasing noise and air pollution as flight operations have grown from 387,000 in 1995 to over 438,000 in 2018. The document calls out regulators and the Port of Seattle for failing to make meaningful progress on commitments such as nighttime flight restrictions, engine run-up controls, and departure corridor compliance.

    Testimony of Dr. Stephen Hockaday before the Subcommittee on Aviation of the House of Representatives Committee on Transportation and Infrastructure

    In 1996 congressional testimony, Dr. Stephen Hockaday argued against building a costly third runway at Seattle-Tacoma International Airport, contending that the Port of Seattle greatly overstated the frequency of poor weather conditions that would require it. He presented evidence that true instrument flight conditions occur less than 8% of the year—not the 44% the Port claimed—and that existing navigation technologies like Localizer Directional Aid approaches could address capacity needs at far lower cost. Hockaday warned that spending half a billion dollars on a runway used only 15% of the time would divert resources from better long-term regional aviation solutions.

    Final Environmental Impact Statement for proposed Master Plan Update development actions at Seattle-Tacoma International Airport, Volume 7 of 7, Appendix T

    This 1996 Final Environmental Impact Statement (EIS), prepared by the FAA and Port of Seattle, evaluates the environmental effects of proposed expansion plans at Seattle-Tacoma International Airport, including construction of a third parallel runway, terminal upgrades, and parking improvements planned through 2020. The document addresses key community concerns such as aircraft noise, air quality, surface traffic, and impacts on wetlands and floodplains. It includes transcripts and written comments from two public hearings held in June 1995, attended by community members and agencies who raised significant concerns about noise, health, and environmental impacts.

    Resolution No. 3202: Declaring certain real property no longer needed for Port’s purposes and surplus to the Port’s needs; and authorizing its sale

    Resolution No. 3202, adopted by the Port of Seattle Commission on October 10, 1995, declares a residential property at 2249 S. 216th Street—acquired through the Seattle-Tacoma International Airport's Transaction Assistance Program for homeowners near airport noise areas—as surplus and no longer needed for Port purposes. The estimated market value of the property was $106,000, and the Director of Aviation Facilities and Maintenance was authorized to arrange its sale on the open market in accordance with state law.

    City of Normandy Park letter to Port Of Seattle re: DEIS – Sea-Tac International Airport Hotel

    In April 1995, the City of Normandy Park submitted formal comments to the Port of Seattle opposing the proposed Sea-Tac International Airport Hotel, raising concerns that the project would increase traffic congestion and reduce parking availability for local, tax-paying air travelers. The city criticized the Draft Environmental Impact Statement (DEIS) for proposing only 15 new parking spaces to serve a 16-story, 384-room hotel that could generate demand for up to 323 garage spaces at peak periods. The city recommended either no action or a smaller-scale hotel alternative that would fully accommodate its own parking needs without negatively impacting existing airport users.

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.
