Draft map (AR 035005, Exhibit 1015) showing restrictive covenant boundaries, sewer line easements, IWS line, Des Moines Creek, and surveyed OHWM on the south end of Seattle-Tacoma International Airport. Identifies the Tyee Valley Golf Course Mitigation Area and Des Moines Creek Mitigation Area, with a note that mitigation was required by the Washington State Department

Port Of Seattle document establishing soil fill quality criteria for Third Runway embankment construction in 1998, covering approximately 820,000 cubic yards of fill material. Specifies Fill Borrow Material Types (Group 1, Group 2, Group 3) with sieve size gradation requirements (6″, 3″, ¾”, U.S. No. 4, U.S. No. 40, U.S. No. 200), MTCA Method A

This document is the professional curriculum vitae of Dyanne Sheldon, principal of Sheldon & Associates, Inc., a Seattle-based wetland ecology consulting firm. Among her relevant work, she co-authored both the Sea-Tac Airport Wetland Inventory and the Sea-Tac Airport Wetland Management Plan in 1991 for the Port of Seattle's Environmental Management Section. Her broader expertise spans wetland delineation, habitat restoration, environmental planning, and regulatory compliance across the Pacific Northwest.

This document is a professional biography and project experience summary for Dr. Don Weitkamp, a fisheries biologist with a Ph.D. from 1976, who has spent decades studying salmon habitat, water quality, and shoreline restoration in the Pacific Northwest. His work has focused on rivers, estuaries, and coastal areas including Commencement Bay, the Green-Duwamish River, and Elliott Bay, involving biological assessments, habitat restoration, and hydroelectric dam impacts. This document does not contain information related to Sea-Tac Airport noise policy.

This document outlines Washington State water quality standards for surface waters, including criteria for total phosphorus levels in lakes across different ecoregions (Cascades and Columbia Basin) and limits for toxic substances such as heavy metals, pesticides, and radioactive materials. It establishes trophic state classifications and action values that trigger lake-specific studies when exceeded, and sets numerical criteria for aquatic life protection in both freshwater and marine environments.

Greg Wingard, an environmental consultant and Executive Director of Waste Action Project, submitted this declaration in a 2001 Pollution Control Hearings Board appeal challenging a permit modification for Seattle-Tacoma International Airport's stormwater discharges. Wingard argues that the modified NPDES permit failed to identify the specific locations of new discharge outfalls into local waterways including Miller, Des Moines, Gilliam, and Walker Creeks, preventing meaningful public participation and environmental review. He contends that without knowing where discharges will occur, it is impossible to evaluate potential cumulative impacts on downstream waterways and riparian property owners.

In this legal declaration, ecologist James C. Kelley, Ph.D., testifies about the environmental impact of Seattle-Tacoma International Airport's Master Plan Update, which permanently fills 18.37 acres of wetland. He describes a comprehensive mitigation plan designed to replace lost ecological functions in the Miller, Walker, and Des Moines Creek basins. Kelley also notes that the affected wetlands and streams were already significantly degraded by decades of logging, farming, and urban development before the airport expansion.

Joseph Brascher, a hydrologic modeling expert at Aqua Terra Consultants, submitted this declaration in a 2001 Washington State Pollution Control Hearings Board case involving the Port of Seattle's Master Plan Update for Sea-Tac International Airport. He describes how the HSPF (Hydrologic Simulation Program – Fortran) computer model was used to analyze stormwater runoff and flow impacts on Miller and Walker Creeks resulting from planned airport construction. The declaration also outlines additional studies and design details requested by the Washington State Department of Ecology as conditions of its §401 water quality certification for the project.
