The Sea-Tac Communities Plan was a joint initiative launched in 1973 by the Port of Seattle and King County, funded in part by the FAA, to address conflicts between Sea-Tac International Airport operations and surrounding neighborhoods—particularly concerns about aircraft noise, property values, and land use. The plan found that while no major airport expansion was needed, noise remained a significant problem requiring a comprehensive remedy program including property acquisition, noise insulation, and purchase guarantees. Key recommendations called for coordinated action by the Port, County, and federal agencies to improve airport-community compatibility over a 20-year planning horizon.Open full document
Notes
The Sea-Tac Communities Plan is a jointly sponsored project initiated in 1973 by the Port of Seattle and King County, funded in part by an FAA grant, to develop a coordinated plan for Sea-Tac International Airport and surrounding communities. The plan addresses aircraft noise impacts, property values, drainage, water quality, and airport access, involving thousands of citizen participants and specialized consultants. Key actions include establishing a comprehensive noise remedy program, improving southern airport access, and implementing a Post-Plan Coordination Program.
