Airport noise mitigation program implementation guidelines
This document outlines how airport noise impact programs can be approved and funded under the Airport Improvement Program (AIP). Once a detailed study confirms substantial community noise impact and a reasonable solution is proposed, costs become eligible for approval. Specific guidelines must then be developed covering property acquisition or sound insulation options, including owner agreements, appraisals, market exposure, noise insulation standards, and relocation proposals. -

Summary — areas of agreement — Workshop #1 — Silence is golden
This document summarizes the areas of agreement reached at Workshop #1, titled 'Silence is Golden,' focusing on Sea-Tac Airport improvements and compatible land use in high-impact noise zones. Participants agreed that the airport is important to the community but has lost its former welcoming atmosphere, and suggested improvements such as lounge seating, art displays, and better amenities. The group also reached consensus that noise-sensitive uses like residences, schools, and hospitals should be prohibited in heavily affected areas, while open space, light industry, and recreational uses were seen as appropriate alternatives. -

Handwritten Notes: FAA Responsibility and Community Complaints Regarding Airline Safety and School Building Use
A community member raises questions about who should accept responsibility for airport-related concerns — the Port of Seattle, King County, the FAA, or local residents who helped plan the N.S.I.P. — noting that the FAA is responsible for safe aircraft use but that following its guidelines could avert greater tragedy in the event of an airline mishap. A separate complaint is also filed against the Highline Public School District regarding the conversion of Boulevard Elementary School and Seaer High School into non-educational facilities, with the writer citing code violations and lack of concern for impact on adjacent neighborhoods. -

Response to comments on the Sea-Tac/Communities Plan Draft Environmental Impact Statement
This document is a formal response to public comments on the Sea-Tac/Communities Plan Draft Environmental Impact Statement, addressing concerns about the airport's Noise Remedy Program. It explains that noise program classifications for petition signers were upgraded due to factors such as summer flight patterns and proximity to approach paths, and that most signers were moved into the Purchase Guarantee area or recommended for the Cost Sharing Insulation Program. The response also notes that no specific schedule exists for noise remedy implementation due to uncertainties in federal funding, and that detailed land-use planning for acquisition areas will involve full citizen participation after properties are acquired. -
Acoustic Weighting Curves 100Hz Red Arrow
A standard audio engineering graph showing the frequency response curves for A-weighting (blue), B-weighting (yellow), C-weighting (red), and D-weighting (black) filters, plotted as Gain in dB versus frequency from 10 Hz to 100 kHz. A red arrow highlights the low-frequency region (~50-80 Hz) where the curves diverge most significantly, particularly relevant to aircraft noise assessment where D-weighting was developed specifically for aircraft noise measurement. -
