    Sea-Tac/Communities Plan work program: Project overview and inventory

    This document outlines the Sea-Tac/Communities Plan, a collaborative airport master planning study conducted by the Port of Seattle and King County with FAA funding, covering environmental, demographic, economic, and land-use impacts of Seattle-Tacoma International Airport on surrounding communities. The $642,000 study, two-thirds funded by a $427,978 FAA planning grant, hired multiple consultants to examine issues including noise exposure, air quality, water quality, and public opinion. The inventory phase aimed to compile comprehensive existing-conditions data within the first six months of the project, starting March 19, 1972.

    Summary of newspaper supplement questionnaire responses

    This document summarizes community questionnaire responses collected as part of the Sea-Tac Communities Plan, asking residents which noise improvement programs—such as property acquisition, sound insulation, easements, and zoning changes—would best meet their personal and neighborhood needs. Results show that acquisition and removal of buildings (Program 2) and purchase guarantees (Program 4) were among the most favored options, while a majority of respondents (60) supported more governmental controls to protect the environment. Open space near the north and south of the airport was most frequently cited as a potential solution to neighborhood problems.
