The Port of Seattle filed an Application for Change/Transfer of Water Right with the Washington State Department of Ecology in June 2000, seeking to add flow augmentation for Des Moines Creek as a purpose of use to an existing well water right (No. 2369) originally used for domestic supply, golf course irrigation, and related uses at Tyee Valley Golf Course in SeaTac. The proposed change would extend the water right beyond 2000 to support creek flow augmentation alongside continued domestic supply and golf course irrigation, covering the Des Moines Creek corridor from the airport property to the creek's mouth at Puget Sound. This application reflects the Port's efforts to manage water resources in connection with environmental and operational responsibilities related to Sea-Tac Airport.

Letter dated June 15, 2000 from Lowell H. Johnson, Manager of FAA Northwest Mountain Region Airports Division, to Steve Landino, Branch Chief of the Washington State Branch of the National Marine Fisheries Service (NMFS), transmitting the Final Biological Assessment (FBA) for Seattle-Tacoma International Airport (STIA) development actions under ESA section 7 consultation. The FBA evaluates

This June 2000 Biological Assessment, prepared by Parametrix, Inc. for the Federal Aviation Administration and Port of Seattle, evaluates the potential environmental impacts of proposed Master Plan Update Improvements at Seattle-Tacoma International Airport on federally listed species. The report examines effects on aquatic resources including Chinook salmon, bull trout, and their critical habitats within nearby waterways such as Miller Creek, Des Moines Creek, and the Green River. It was prepared to support Section 7 consultation under the Endangered Species Act with the U.S. Fish and Wildlife Service and National Marine Fisheries Service.

Email from Andy McMillan (SEA program) dated June 12, 2000, forwarded by Tom Luster to Raymond Hellwig on October 6, 2000, transmitting the official version of a Word document titled “Lessons Learned from Big Projects: Recommendations for SEA Program.” The attached document outlines 7 recommendations developed from SEA program staff experiences with large, complex projects

Email dated June 12, 2000 from Erik Stockdale (Wetlands Specialist, Washington State Department of Ecology) to Jim Kelley (Parametrix) and Elizabeth Leavitt (Port of Seattle), summarizing a June 9, 2000 conversation regarding the Wildlife Hazard Management Plan (WHMP) and its consistency with the Natural Resource Mitigation Plan (NRMP) and 401 water quality certification. Stockdale outlines

A fisheries biologist hired by the Airport Communities Coalition assessed the potential environmental impacts of a temporary SR-509 interchange construction project near Seattle-Tacoma International Airport, concluding that the project posed serious risks to fish and wetland resources in Walker Creek. The report found that proposed erosion control measures, such as silt fences and whattles, were grossly inadequate given the steep terrain (slopes of 40–60%) adjacent to Wetlands 43 and 44, and that sediment-laden stormwater runoff containing metals and polycyclic aromatic hydrocarbons would likely reach these sensitive areas. The biologist also criticized the Port of Seattle and its contractor, Parametrix, Inc., for failing to conduct fish species inventories and for providing little documentation to support their claim that no significant wetland impacts would occur.

A June 2000 letter from Azous Environmental Sciences to the US Army Corps of Engineers raises concerns about the incorrect mapping of Wetland 44a near the proposed SR509 temporary interchange in SeaTac, Washington. A field review found that the wetland may be 20 to 40 feet closer to the construction zone than shown in project plans prepared by HNTB Corporation, potentially exposing it to significant sediment runoff during construction. The letter also highlights an overlooked creek system connecting Wetland 44a to Walker Creek and Miller Creek, warning that construction impacts could affect a broader network of wetlands and waterways.
