Resolution No. 3482, adopted by the Port of Seattle Commission on February 12, 2002, authorized the acquisition of two mobile home parks in Burien — Burien Gardens and Flora Vista — located within the 70 DNL aircraft noise contour near Seattle-Tacoma International Airport. Because noise-insulating mobile homes is not cost-effective, the resolution directed Port staff to develop a plan for purchasing both properties and relocating their approximately 102 tenants in accordance with federal guidelines. The resolution amended an earlier measure (Resolution No. 3443) and allowed the Port to proceed before receiving final FAA approval of the FAR Part 150 Study Update.

Port Of Seattle’s Motion for Partial Summary Judgment filed in PCHB Case No. 01-160 before the Pollution Control Hearings Board for the State of Washington, opposing ACC (Airport Communities Coalition) claims that Ecology’s 401 Certification is invalid due to SEPA non-compliance. The motion argues six independent grounds for dismissal of Agreed Issue No. 14 (‘Did

Declaration of Michael Feldman, Director of Aviation Facilities and Environmental Programs at Port Of Seattle, filed in PCHB Case No. 01-160 (Airport Communities Coalition v. Department of Ecology and Port Of Seattle). Feldman attests to the history of environmental review for the Sea-Tac Airport Master Plan Update, including the 1996 FEIS, May 1997 SEIS, FAA

This declaration by Paul Fendt, a licensed civil engineer with over 18 years of stormwater experience, was submitted in support of the Port of Seattle's opposition to the Airport Communities Coalition's motion in a 2001 Washington Pollution Control Hearings Board case. Fendt explains how new airport development and impervious surfaces can impact local waterways by increasing runoff and reducing groundwater recharge, and describes the stormwater management systems required by the Washington Department of Ecology for the Port of Seattle's Master Plan Update projects. The document provides technical background on stormwater best management practices (BMPs) and regulatory requirements under Washington State and federal Clean Water Act permits.

A February 2002 letter from Marten Brown attorneys transmits two spreadsheets listing reference documents used by expert witness John Strunk in the case ACC and CASE v. Port of Seattle and Department of Ecology (PCHB No. 01-160). The spreadsheets catalog technical reports and studies related to preferential ground water flow paths near the proposed Third Runway at Seattle-Tacoma International Airport, covering sites such as airline fuel farms, maintenance hangars, and contaminated ground water areas. Documents were produced by environmental consultants including Associated Earth Sciences and EMCON, spanning reports from the mid-1990s through 2001.

Stipulation and Agreed Order filed February 8, 2002, in Pollution Control Hearings Board case PCHB No. 01-160, involving Airport Communities Coalition (ACC) and Citizens Against Airport Expansion as appellants against State of Washington Department of Ecology and Port Of Seattle as respondents, concerning Clean Water Act Section 401 Certifications #1996-4-02325 and #1996-4-02325 (Amended-1). Parties including

A February 2002 technical review by GeoSyntec Consultants, submitted to the U.S. Army Corps of Engineers, raises serious concerns about the Port of Seattle's low flow water analysis for the Sea-Tac Airport Third Runway expansion project. The review argues that the Port's models fail to account for the years-long delay before water would flow through the new embankment fill and reach surrounding creeks, potentially leaving those creeks without adequate water during the critical early years of operation. GeoSyntec concluded that the proposed underground storage vaults may be significantly undersized and that the Port has not reliably demonstrated the project will meet required streamflow conditions.

A February 2002 technical letter from GeoSyntec Consultants, submitted to the U.S. Army Corps of Engineers on behalf of the Airport Communities Coalition, raises serious concerns about the Port of Seattle's water flow analysis for the proposed Sea-Tac Third Runway expansion. The letter argues that the Port's analysis fails to account for the years-long delay before water would flow through the new embankment fill into drainage systems, potentially leaving nearby creeks without adequate water during the critical early years of operation. GeoSyntec concludes that the storage vaults designed to protect creek water levels may be significantly undersized due to flawed modeling assumptions and an overestimation of how quickly water would move through the embankment soil.

A February 2002 technical letter from GeoSyntec Consultants, written on behalf of the Airport Communities Coalition, raises concerns about the Port of Seattle's low flow analysis for the Sea-Tac Airport Third Runway expansion project. The letter argues that the Port's analysis fails to account for the years-long delay before water would flow through the new embankment fill into drainage systems feeding nearby creeks, potentially leaving those creeks without adequate water during the critical early years of operation. GeoSyntec concludes that the Port has not demonstrated the project's storage vaults are properly sized, and that the underlying computer models are unreliable due to lack of calibration and flawed assumptions about soil hydraulic conductivity.

A February 2002 technical letter from GeoSyntec Consultants, submitted to the U.S. Army Corps of Engineers on behalf of the Airport Communities Coalition, raises serious concerns about the Port of Seattle's water flow analysis for the Sea-Tac Third Runway expansion project. The report argues that the Port's analysis fails to account for the years-long delay before water would flow through the new embankment fill and reach surrounding creeks, potentially leaving those creeks without adequate water during the critical early years after construction. GeoSyntec concludes that the storage vaults designed to protect creek water levels are likely undersized and that the Port has not reliably demonstrated the project will meet low streamflow requirements.
