Published in June 1980 by the Federal Interagency Committee on Urban Noise, this document provides guidelines for incorporating noise considerations into land use planning and control decisions. It was produced jointly by the U.S. Department of Transportation, Department of Defense, Environmental Protection Agency, and Department of Housing and Urban Development. The guidelines are intended to help planners and policymakers manage the impact of noise—such as that generated by airports like Sea-Tac—on surrounding communities through zoning and land use strategies.

A March 1980 internal memo from Bob Wells of the Planning department transmits Noise Monitoring System reports for January and February 1980 to Marion MacKenzie, noting that the station map quality is poor while a clearer version is being prepared. The accompanying report for Sea-Tac International Airport shows monthly and long-term average Day-Night Sound Level (LDN) readings across nine remote monitoring stations, with January 1980 values ranging from 73 to 84 dBA. Operational notes indicate that 58% of January air traffic flew north to south, heavy snowfall forced a brief airport closure on the 8th–9th, and two minor clock failures in the monitoring system were corrected without any loss of noise data.

A July 25, 1979 Port of Seattle internal memorandum from James Branch to all departments and staff compiles 23 questions raised by the public at a Zone Three Steering Committee meeting held on July 24, 1979. The questions cover a wide range of community concerns related to Seattle-Tacoma International Airport, including aircraft noise levels, flight path enforcement, land acquisition programs, runway expansion plans, clear zone definitions, and jet engine emissions affecting nearby neighborhoods. The memo also addresses topics such as FAR 36 noise standards, the Sunset Recreation Plan, the ADAP program, and how residents of the Highline and Zone 3 communities can better cooperate with the Port of Seattle to resolve ongoing airport-related issues.

Published in March 1979 by the National Association of Counties Research, Inc., this guide examines how local governments can use land use controls—such as zoning and planning regulations—to reduce the impact of noise on residential communities. It covers noise sources including highway and transportation corridors, offering practical strategies for buffering noise-sensitive land uses from high-noise areas. The document is a foundational reference for planners and policymakers working to protect communities from airport, highway, and industrial noise.

This 1979 article from the Port of Seattle's Tradelines newsletter describes the Sea-Tac/Communities Plan, a pioneering cooperative effort between the Port of Seattle, King County, and the FAA to address aircraft noise impacts on neighborhoods surrounding Sea-Tac International Airport. Rather than focusing solely on reducing noise at its source, the plan targeted the affected communities directly through measures such as home acquisitions in severely impacted areas, 'purchase guarantees' for moderately impacted zones, and residential insulation cost-sharing programs. Adopted in 1976, the plan is presented as an innovative model for airport-community compatibility planning, though the article acknowledges it represents only a partial solution to the broader challenges airports and their neighboring communities face.

This document presents F.A.A. Density Guidelines for North Sea-Tac Park, a neighborhood near Seattle-Tacoma International Airport. It maps out population density limits across different zones, ranging from 1.5 people per acre in the Clear Zone closest to the airport, to 2 people per acre in the Extended Clear Zone, up to 20-40 people per acre in areas farther from the runway. The guidelines reflect FAA safety and noise policy restrictions that limit how many residents can live in areas most directly affected by airport flight paths.

In this September 1977 letter, Port of Seattle Executive Director Richard D. Ford responds to a community member's concerns about the Concorde supersonic jet, expressing alarm that the Federal Government amended its noise regulations to allow a noisier aircraft to operate at U.S. airports. Ford warns this decision undermines the Sea-Tac/Communities Plan, which was built on the expectation that aircraft would become progressively quieter over time. He calls on the federal government, airlines, and aircraft manufacturers to aggressively pursue quieter engine technology as a necessary solution to airport noise problems.

This 1976 Federal Aviation Administration report documents the data library underlying the FAA Integrated Noise Model (INMPROG), a computer program used to calculate various noise exposure indices around airports. The library contains both acoustic measurements and operational flight procedure data for standard aircraft types. The report serves as a reference for analysts seeking to reproduce noise studies or customize the model with their own flight procedures.

In a May 1976 letter to King County Councilwoman Bernice Stern, Seattle Port Commission President Henry T. Simonson outlined two key decisions regarding land adjacent to Sea-Tac International Airport. The Port ruled out acquiring the 35-acre 'west acquisition area' due to high costs, excessive development expenses, and lack of foreseeable airport-related demand, while agreeing that any existing development there must follow carefully formulated guidelines. For the 'southeast conversion area' — 85 small homes in Lowe's Terrace Subdivision — the Port acknowledged that standard acoustic insulation treatment may not be cost-effective, and flagged the neighborhood as a candidate for a special purchase guarantee program to assist with gradual land-use conversion.

A 1975 study by Bronzaft and McCarthy examined how noise from passing elevated subway trains affected the reading ability of elementary school children at a New York City school located approximately 220 feet from the tracks. Researchers compared reading scores of students in classrooms on the noisy train-facing side of the building versus the quieter opposite side, finding that chronic exposure to loud, unpredictable noise was associated with measurable reading deficits. The findings built on earlier research suggesting that children in high-noise environments struggle to distinguish relevant speech cues, which can hinder their ability to learn to read.
