TagSea-Tac Communities Plan(240)

This document outlines a multi-phase airport noise reduction program, likely for Sea-Tac Airport, detailing proposed projects from 1975 to 1994 with estimated costs ranging from tens of thousands to millions of dollars. Projects include land acquisitions in north and south areas, purchase guarantee programs, major and limited noise insulation programs, and noise monitoring systems. Implementation responsibilities are shared between primary and secondary agencies, with funding requiring commitments beyond normal existing sources and, in some cases, significant administrative or legislative changes.

This map shows the Des Moines and SeaTac area of Washington State, highlighting a noise impact corridor (shown in teal) that sweeps across the region near Sea-Tac Airport. The corridor passes over several schools including Mt. Rainier High School, Pacific Middle School, Midway Elementary, St. Philomena School, and Des Moines Elementary, indicating these institutions fall within the airport's noise-affected zone. A separate boundary (shown in orange) outlines what appears to be an airport-related land use or acquisition area in the southern portion of the map near Interstate 5.

King County Ordinance No. 8996, adopted April 3, 1989, updates comprehensive land use planning and zoning for the Sea-Tac Airport area, incorporating community input and environmental review to guide orderly development near the airport. The ordinance formally adopts the Sea-Tac Area Update and Area Zoning as official county policy, amending several prior ordinances related to the Highline Communities Plan. It also establishes policies for the development of North Sea-Tac Park, with safety designated as the foremost planning consideration.

The August 1985 Sea-Tac Forum newsletter covers updates to the Port of Seattle's Noise Remedy Program, including plans to acquire 524 additional homes near the airport between 1986 and 1990, on top of the 788 already being purchased. It also announces the expansion of the airport's noise monitoring system from 9 to 11 sensors, the appointment of a new noise abatement manager, and the introduction of quieter Stage 2 and Stage 3 aircraft by tenant airlines. Additional items include a proposed national veterans cemetery on land south of the airport and a call for volunteers to help manage North Sea-Tac Park.

This document outlines the workshop agenda for the King County Planning and Community Development Committee's General Development Guide, chaired by Councilwoman Cynthia Sullivan of District 2. The 110-minute session included a staff presentation, a Muni League-led explanation of the public input process, and small group discussions where residents were asked to share community concerns with the Council. Citizens selected from small groups reported back their findings, followed by brief public comments and concluding remarks from Sullivan.

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.
