The Federal Aviation Administration approved a total grant payment of $4,935,000 to the Port of Seattle for AIP Project Number 3-53-0062-77, covering acoustical insulation work at Seattle-Tacoma International Airport. Out of $6,476,538.99 in claimed costs, $6,168,750.00 was deemed allowable after disallowing $307,788.99, with the federal share set at 80%. The Port of Seattle submitted closeout documentation in March 2006, though a Circular A-133 audit by Deloitte & Touche and final acoustic test results for Seawind Condominiums were still pending completion at the time of closure.

In September 2003, the Port of Seattle Commission considered authorizing a $3.69 million program to sound-insulate 98 single-family homes near Sea-Tac Airport that fell within the projected 2010 65 DNL noise contour and were built before local noise codes took effect. The project, stemming from a 1997 Environmental Impact Statement related to the airport's third runway, aimed to reduce interior noise levels by at least 5 decibels in eligible homes in Des Moines and unincorporated King County. Funding was to come primarily from federal Airport Improvement Program grants (80%), with the remainder drawn from the Airport Development Fund, and homeowners were required to grant the Port an avigation easement in exchange for the insulation work.

In January 2002, the Port of Seattle Commission passed Resolution No. 3483 to formally support the Highline School District's $189.5 million Capital Facilities Improvement Bond, which was on the March 12, 2002 ballot. The resolution reaffirmed the Port's commitment to contribute $50 million as part of a $200 million partnership with Washington State and the FAA for noise insulation and ventilation improvements at the 15 Highline schools most impacted by Seattle-Tacoma Airport aircraft noise. The funding partnership was contingent on Highline District voters approving the bond measure, which would also finance broader facility and technology upgrades across the district's aging school buildings.

This document compiles evidence alleging that the Port of Seattle violated Federal Grant Assurance C.6 and Washington State law RCW 53.54.020 in connection with its noise compatibility program at Sea-Tac Airport. It includes letters from elected officials, audit findings by Deloitte & Touche, and records showing the Port received over $100 million in federal funds for FAR Part 150 noise mitigation while allegedly failing to comply with the program's requirements. Supporting materials span 1990–1998 and involve Congress members, state legislators, the FAA, and the Washington State Auditor's Office.

This Home Owner's Instruction Manual was produced under the Port of Seattle's Sound Reduction Program and covers vinyl window and door products installed by CARE-FREE Windows and contractor SKM Construction. It explains how to care for and operate the PVC windows, which are designed to reduce aircraft noise, improve weatherization, and resist drafts and condensation. All CARE-FREE Windows products are backed by a 10-year guarantee covering defects in materials and workmanship from the date of purchase.

The MAC Part 150 Residential Sound Insulation Program completed sound insulation work on 3,673 homes near Minneapolis-St. Paul International Airport between 1992 and 1997, at a total cost of $76.6 million. Funding came from two sources: $28.7 million in FAA Airport Improvement Program (AIP) grants and $48.6 million in MSP Passenger Facility Charges (PFC). The program grew significantly over its six-year run, peaking in 1996 with 1,002 homes insulated at a cost of $20.7 million.

This document presents the Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments, submitted by the Port of Seattle and approved by the Federal Aviation Administration on May 18, 1994. It outlines a series of noise mitigation measures—including sound insulation programs for homes and public buildings, a transaction assistance program for affected property owners, and an expanded noise monitoring system—aimed at reducing noncompatible land uses around Sea-Tac Airport. Three new measures were also recommended, covering funding for land use planning, a community planners forum, and ongoing operations review and noise exposure map updates.

This document presents the Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments, submitted by the Port of Seattle and approved by the Federal Aviation Administration on May 18, 1994. It outlines updates to existing noise-reduction measures—including sound insulation for homes and public buildings, a transaction assistance program, and an expanded noise monitoring system—as well as newly recommended measures such as community planning forums and operational reviews. The program aims to reduce noncompatible land uses around Sea-Tac Airport and prevent the introduction of new ones.

Since 1982, Seattle-Tacoma Airport (Sea-Tac) has received 13 federal AIP grants totaling over $50 million to acquire approximately 750 noise-impacted land parcels near the airport. In addition, four federal grants totaling over $7 million have funded a noise insulation program that has treated 323 homes, with further funding of $3.2 million per year requested to insulate roughly 175 additional houses annually over the next four years.
