TagEnvironmental Impact Statement(140)

This 2004 King County decision concerns a permit application by Glacier Northwest (Northwest Aggregates) to mine and export sand and gravel from Maury Island and replace an aging barge-loading dock on Puget Sound. The project proposed replacing 228 old creosote timber piles with 62–82 steel piles, extending the dock further into the water to protect nearby eelgrass beds, and enclosing the conveyor in a steel pipe to reduce spillage and noise. Note: this document relates to a Maury Island mining and shoreline development project and does not contain information about Sea-Tac Airport noise policy.

A 2003 Port of Seattle memo updates the Commission on the ballooning costs of the Sea-Tac Third Runway project, which had grown from an approved budget of $773 million to an estimated $1.1–1.15 billion due to environmental permitting delays, litigation, and stricter regulatory requirements. The project, intended to reduce airport congestion by allowing simultaneous landings on two runways during poor weather, was projected for completion in 2008 if construction contracts were advertised promptly. Key cost drivers included $151 million in additional environmental permit requirements, $55 million in delay costs, and $55 million in project scope additions.

This document is a catalog of 31 reports and studies published in 1999 related to Sea-Tac Airport expansion and environmental review, including wetland assessments, stormwater monitoring, subsurface conditions reports, and community health studies. Sources range from the Port of Seattle and U.S. Army Corps of Engineers to environmental consultants such as Parametrix and Hart Crowser. The materials primarily concern the proposed third runway project and its impacts on local ecosystems, waterways, and surrounding communities.

This 2002 executive briefing presents the draft Master Plan and environmental review documents (SEPA/EIS and NEPA/EA) for King County International Airport (Boeing Field), located five miles south of downtown Seattle. The airport, which covers 594 acres and hosts 150 tenant businesses and 479 based aircraft, recorded approximately 290,000 flight operations in 2001. The FAA accepted the Master Plan in Fall 2001 and approved the Airport Layout Plan in March 2002, setting the stage for future development and noise impact assessments.

This August 2002 document outlines proposed Master Plan Update improvements at Seattle-Tacoma International Airport (Sea-Tac), submitted by the Port of Seattle. It details construction projects including a third runway, runway safety areas, terminal expansions, and air cargo facilities, along with wetland impact mitigation measures in the Miller Creek Basin. The plans include on-site and off-site wetland mitigation areas, MSE retaining walls to minimize environmental impacts, and creek relocations across multiple sections of King County, Washington.

This catalog lists documents published in 1994 related to Seattle-Tacoma International Airport (Sea-Tac), covering topics such as aircraft noise, environmental impact statements, airport master plan updates, and regional transportation planning. Sources include the Port of Seattle, the FAA, PSRC, and various aviation consultants, with materials ranging from budget reports and feasibility studies to public briefings and technical reports. The catalog serves as an archival index for researchers and policymakers studying airport expansion, noise management, and aviation growth in the Puget Sound region during the mid-1990s.

This document outlines the U.S. Army Corps of Engineers' analysis of a December 2000 mitigation plan developed by the Port of Seattle to offset wetland impacts caused by the construction of a third runway at Seattle-Tacoma International Airport. The plan covers roughly 18.6 acres of on-site wetland restoration near the airport—including the relocation of a stretch of Miller Creek and improvements to Lora Lake's shoreline—as well as 23.39 acres of off-site wetland mitigation in Auburn. Key goals include improving water quality, restoring floodplain and fish habitat, and managing vegetation to reduce wildlife hazards such as bird strikes near the airfield.

This catalog lists documents published or issued in 1997 related to Seattle-Tacoma International Airport (Sea-Tac), covering topics such as master plan updates, environmental impact statements, noise exposure studies, and water quality reports. Key items include FAA Records of Decision, draft and final Supplemental Environmental Impact Statements, FAR Part 150 Noise Exposure and Land Use Compatibility Studies, and public comments from regional commissions and advocacy groups. The collection serves as a reference archive for researchers and stakeholders interested in Sea-Tac Airport's development, noise policy, and environmental compliance during the late 1990s.

This catalog lists documents received in 1992 related to aviation planning and noise policy in the Puget Sound region, with a focus on Sea-Tac International Airport (STIA). It includes environmental impact statements, noise exposure maps, community association comments, budget documents, and FAA regulatory guides, many connected to the 'Flight Plan Project' — a regional air transportation study. Several items were donated by attorney J. Richard Aramburu and other community stakeholders involved in airport noise and development issues.

This is a library catalog listing documents from 1995 related to Sea-Tac International Airport's planned expansion, including a third runway proposal. The documents cover environmental impact statements, noise studies, community group objections, legal appeals, and financial analyses from sources such as the FAA, Port of Seattle, and local community associations. The catalog was compiled to track public records and research materials relevant to airport noise policy and development decisions in the Seattle region.
