This document summarizes the Sea-Tac Communities Plan, a 1973 joint study by the Port of Seattle and King County to improve compatibility between Sea-Tac International Airport and its surrounding neighborhoods. The plan examined aircraft noise exposure, air and water quality, and community growth, finding that noise levels were expected to decrease over time due to quieter aircraft technology despite rising flight operations. It proposed a range of noise remedy programs—including property acquisition, purchase guarantees, and insulation assistance—affecting thousands of homes in areas north and south of the airport.

This 1984 Port of Seattle staff report outlines updates to the Sea-Tac Airport Noise Remedy Program, reviewing and adjusting boundaries for three areas: property acquisition, neighborhood reinforcement (purchase assurance), and cost-sharing insulation. The update incorporates revised noise data from 1980 aircraft operations and considers recommendations from a consulting firm (Peat Marwick & Mitchell) and a citizen subcommittee. Staff ultimately recommended boundaries based primarily on noise criteria, with adjustments to account for forecasting uncertainty and long-term program stability over the following fifteen years.

This April 1984 working draft outlines the Port of Seattle's suggested process for helping eligible homeowners near Sea-Tac International Airport sell their properties under the Neighborhood Reinforcement Program's Purchase Assurance Noise Remedy Option. Homeowners first list their homes on the market for a minimum of 90 days, and if unsold, may apply to the Port for transaction assistance, which can include a property appraisal, noise audit, mortgage subsidies, and partial real estate fee coverage. Depending on how the appraisal compares to the final listed price, the Port may acquire an avigation easement, assist with the sale, or ultimately purchase the property itself and market it for resale.

This April 1984 working draft, prepared by Peat, Marwick, Mitchell & Co. and the Port of Seattle Planning & Research, outlines a suggested process for assisting property owners in the neighborhoods surrounding Sea-Tac International Airport under a Purchase Assurance Noise Remedy Option. The document details goals, objectives, and policies from the 1976 Sea-Tac Communities Plan, including minimizing aircraft noise, protecting residential neighborhoods, and resolving uncertainty caused by noise impacts. It reflects the Port of Seattle's broader commitment to keeping the airport operational while mitigating its effects on surrounding communities.

In December 1983, the Port of Seattle invited community members to review preliminary boundaries for three proposed noise remedy programs near Seattle-Tacoma (Jackson) International Airport: land acquisition, purchase assurance, and sound insulation. Consultant firm Peat Marwick recommended eligibility criteria for sound insulation, targeting single-family homes exposed to noise levels of Ldn 70 or above in 1980, or Ldn 65 or above projected for the year 2000. Residents were encouraged to submit comments on the proposed boundaries and criteria by January 31, 1984.

This November 1983 document outlines the Master Plan Update for Jackson International Airport (Sea-Tac), prepared by Peat Marwick and TRA for the Port of Seattle. It presents a nine-month project schedule covering 13 elements—ranging from study design and passenger surveys to alternative layout plans and a financial development schedule—along with a project organization chart showing the Port of Seattle's steering committee and staff alongside federal and consulting partners.

This 1983 report by McClure Research Company, prepared for Peat Marwick Mitchell & Co., presents findings from community attitude surveys conducted on behalf of the Port of Seattle as part of an update to the 1976 Noise Remedy Plan for neighborhoods surrounding Seattle-Tacoma International Airport. The surveys gathered residents' opinions on noise mitigation options including purchase guarantees, home insulation cost-sharing, and avigation easement buyouts, as well as broader issues like park usage and residential development near the airport. The results were intended to help planners gauge community acceptance, estimate program participation rates, and determine appropriate levels of Port financial involvement in noise remedy programs.
