    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.

    City of Naples City Council and Naples Airport Authority Joint Workshop Meeting Minutes – September 12, 2022

    Minutes from a September 12, 2022 joint workshop between the Naples, Florida City Council and Naples Airport Authority cover discussions on the Airport Master Plan, noise reduction efforts, and community concerns about increasing jet traffic. Key topics included raising aircraft flight path ceilings to reduce noise, the possibility of reclassifying Naples as a Class C airport, and whether the Master Plan's growth projections were already outdated given a 40% surge in jet traffic. Residents and neighborhood association representatives called for equitable distribution of noise impacts and urged immediate action rather than waiting for a formal noise study to be completed.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
