Port of Seattle memorandum announcing the second Airspace Study Advisory Committee meeting scheduled for February 24, 1982. The agenda includes aviation demand forecasts for Sea-Tac and Boeing Field, discussion of airfield and airspace capacities, and aircraft delays.

In a January 29, 1982 letter to the Port of Seattle's Director of Planning and Research, Riverton Heights community representative William C. Holstine outlined several concerns about Sea-Tac Airport noise management, including calls for annual calibration of noise-measuring equipment, independent auditing of the Perry Company's noise study, and additional community-level noise measurements beyond the existing fixed monitoring stations. Holstine argued that existing remedies such as property acquisition and purchase guarantees should not be delayed while new solutions were being studied, and stressed that a five-to-ten-year timeline for resolving aircraft noise impacts—after already waiting ten years—was unacceptable to his community. He urged the Port to expedite and expand its noise remedy programs, drawing a comparison to the Port's willingness to fund other major projects like the Shilshole Marina expansion and the West Seattle Bridge.

In this January 1982 letter, Port of Seattle Planning Director Clifford C. Muller responds to community member Virginia Dana's concerns about the Sea-Tac Airport Noise Exposure Update Study. He addresses skepticism over the Ldn noise measurement system, defends the study's prediction that noise impact will decrease as airlines adopt quieter aircraft, and reassures Dana that shrinking noise contours do not eliminate eligibility for noise remedy programs. Muller acknowledges that the Technical Advisory Committee's input has been valuable and indicates that the upcoming Remedy Plan project will be the primary venue for addressing ongoing community concerns.

A January 1982 letter from the FAA's Northwest Region to the Port of Seattle reviews a draft aviation demand forecast for Boeing Field (BFI) prepared for the SEA/BFI Airspace Study. The FAA requests that the final report include more detailed aircraft mix data by class, a full list of assumptions behind the forecasts (such as economic conditions, fuel costs, and general aviation trends), and a clear indication that the projections are unconstrained. The agency also recommends presenting both high and low forecast ranges to account for uncertainty, particularly in long-range general aviation projections.

In January 1982, members of the Technical Advisory Committee for the Sea-Tac International Airport Noise Exposure Update wrote to the Port of Seattle's Director of Planning and Research to raise concerns about the final draft of the noise study. The letter argues that the report fails to clearly define the problem of aircraft noise impacts on surrounding communities, relies on optimistic assumptions about airlines adopting quieter aircraft, and uses an average noise level methodology that does not capture how residents actually experience flight disruptions. The committee also expressed frustration that their technical input and unanswered questions were largely ignored, despite their role being cited in the report as evidence of public participation.

A December 29, 1981 letter from Port of Seattle Chairman Oris W. Dunham, Jr. notifies Policy Advisory Committee members that their upcoming meeting has been rescheduled from January 13 to January 14, 1982 at 2:00 p.m. in Sea-Tac's auditorium due to a scheduling conflict. The primary focus of the meeting remains the Noise Exposure Update, with additional agenda items also planned for discussion. Members were advised that the final agenda would be mailed during the first week of 1982.

In a December 28, 1981 memorandum from Boeing Field/King County International Airport, Airport Manager Donald W. Smith responds to a Port of Seattle representative regarding the forecasting methodology for aviation demands at BFI. Smith confirms that the proposed approach is consistent with prior discussions and historical statistics, and acknowledges that, given limited current information and resources, the methods and sources used are acceptable.

In this December 1981 letter, members of the Technical Advisory Committee for the Sea-Tac International Airport Noise Exposure Update write to the Port of Seattle's Director of Planning and Research to raise concerns about the final draft of the noise study. They argue that the report fails to define the core problem of aircraft noise impacts on surrounding communities, relies on optimistic assumptions about quieter aircraft that may not materialize, and uses an average noise level methodology that does not reflect how residents actually experience noise. The committee also expresses frustration that their technical input was largely ignored, and that their participation appeared to serve mainly as a formality to meet public participation requirements.

This 1981 Memorandum of Understanding between the Port of Seattle and King County outlines terms for reclassifying approximately 30 acres of land on the west side of Sea-Tac International Airport to allow Boeing to develop a Corporate Headquarters Facility. The agreement includes provisions for the Port to lease 5 acres to King County for a neighborhood park at $1 per year, and restricts development on an adjacent 55-acre greenbelt buffer zone for at least 10 years. The document also affirms King County's zoning authority over non-airport-related land use at Sea-Tac and establishes a dispute resolution process between the two agencies.

A November 1981 letter from Sea-Tac International Airport Chairman Oris W. Dunham Jr. notifies Policy Advisory Committee members of an upcoming meeting scheduled for January 13, 1982, at 2:00 p.m. in Sea-Tac's auditorium. The primary agenda item is a Noise Exposure Update. Committee members wishing to add agenda items or ask questions were directed to contact Beverly Boster at 433-5388.
