Ground Water Flow Map for the C1 Aquifer prepared by Associated Earth Sciences, Inc. (project no. 8V07019, figure 7) as part of a Ground Water Study at Seattle-Tacoma International Airport, dated 12/02/99. The map covers the Sea-Tac Airport area including Normandy Park, City of SeaTac, Tukwila, Des Moines, and surrounding Puget Sound shorelines. Shows ground

This 1999 document by C. Gower describes the Miller Creek Basin, a historic Puget Sound salmon stream located in the cities of SeaTac, Burien, and Normandy Park in King County, Washington (Water Resource Inventory Area No. 9). The basin includes several lakes — Arbor, Tub, Reba, Lora, and Burien — and drains into Puget Sound via Miller Creek and Walker Creek. The map highlights the proposed Third Runway site at Sea-Tac Airport within the watershed, raising concerns about potential environmental impacts to this salmon-bearing stream system.

BioAnalysts, Inc. report by T.W. Hillman, J.R. Stevenson, and D.J. Snyder prepared for Airport Communities Coalition (ACC), Des Moines, WA. Surveys of habitat composition and condition, redd (nest) abundance and distribution, and spawning population characteristics of coho (Oncorhynchus kisutch), chum (O. keta), and cutthroat trout (O. clarki) in Miller Creek, Walker Creek, and Des Moines

This catalog log lists three transportation planning documents received in 1991 and accessioned into an archive between 2001 and 2003. The documents cover Puget Sound regional transportation alternatives (the Flight Plan Project), air pollutant contributions at Seattle-Tacoma International Airport, and a feasibility study for preserving the Stampede Pass Rail Corridor. Together they represent early 1990s regional planning efforts related to air quality, rail, and transportation policy in the greater Seattle-Tacoma area.

WAC Chapter 173-201A establishes water quality standards for surface waters of the State of Washington under RCW 90.48, including definitions for AKART, background conditions, best management practices (BMP), fecal coliform, mixing zones, pH, turbidity, wetlands, nonpoint source pollution, and trophic state. Covers general water use and criteria classes (Class AA extraordinary), dissolved oxygen standards, fecal

This 1996 Puget Sound Regional Council document summarizes the multi-year planning process behind the decision to add a third runway at Seattle-Tacoma International Airport. It traces efforts dating back to the 1988 Regional Airport System Plan through environmental reviews, expert panel evaluations, and feasibility studies, concluding that no viable alternative sites or demand-management strategies could eliminate the need for the new runway. The approval was conditioned on additional noise reduction measures to address impacts on surrounding communities.

The 1994 Puget Sound Water Quality Management Plan is a regional environmental policy document adopted on May 18, 1994 by the Puget Sound Water Quality Authority, based in Olympia, Washington. It outlines strategies and guidelines for managing and protecting water quality across the Puget Sound region. Note: This document pertains to water quality management and does not contain content related to Sea-Tac Airport noise policy.

A January 28, 1993 letter from James T. Murphy of the Regional Commission on Airport Affairs (RCAA) to the Transportation Policy and Executive Board, presenting independent consultant research on air capacity options for the Puget Sound region. The letter notes that RCAA had delivered three volumes of material over three weeks, with a final compilation to follow, aimed at helping the Board make informed decisions about managing airport capacity. The RCAA, backed by dozens of community organizations and cities including Burien, Des Moines, Normandy Park, and Tukwila, framed its work as an alternative voice on Sea-Tac Airport expansion and noise policy.

In 1991, the Puget Sound Air Transportation Committee (PSATC) gathered public input on long-term air capacity solutions for the Seattle region, with over 1,200 people participating through meetings and written comments. Key public concerns included opposition to expanding Sea-Tac Airport, worries about noise and air pollution impacts on nearby residents, and support for high-speed rail alternatives. The committee identified several potentially feasible options—including multiple airport systems and a new international airport to replace Sea-Tac—while ruling out others, such as a distant remote airport and high-speed rail alone, as insufficient stand-alone solutions.
