TagAuburn Wetland(82)

The Auburn Mitigation Site is an 80-acre wetland restoration project in the Green River floodplain, created by the Port of Seattle to offset natural resource impacts from Seattle-Tacoma International Airport's third runway construction. The site features forested, scrub-shrub, and emergent wetlands that provide 40 acre-feet of floodplain storage, while keeping waterfowl habitat away from the airport to reduce bird-strike hazards to aircraft. As of 2013, the Port was in Year 6 of a 15-year monitoring program, with most communities successfully maturing and meeting performance standards after targeted removal of invasive species such as reed canary grass and cattail.

In this 2004 declaration filed with the Washington Supreme Court, Robin V. Kordik, a Senior Environmental Program Manager for the Port of Seattle's Aviation Division, describes efforts to identify wetland mitigation sites near Sea-Tac Airport in connection with the airport's Third Runway construction project. A study by environmental firm Parametrix assessed 89 potential mitigation locations but concluded that no suitable new sites were available in the affected sub-basins that met the Pollution Control Hearings Board's criteria for sustainability and public safety. The declaration was submitted in opposition to a motion for injunctive relief brought by the Airport Communities Coalition.

This document, labeled Exhibit E, contains photographs taken on January 31, 2002 of the Vacca Farm site, showing various land features including areas designated as Prior Converted Cropland, farmed wetlands, and Wetland A1. The photos document the site's vegetation and water features, including a close-up of wetland plants and a view of Miller Creek looking west across Wetland A1. The images appear to be part of an environmental or land-use assessment record related to the Vacca Farm property near Des Moines Way.

Handwritten field observation notes by R. Azous (Azous Exhibit 387, dated 2-19-02) transmitted via fax from Helsell Fetterman LLP on 02-19-2002, documenting site visits to Vacca Farm and West Side areas adjacent to Miller Creek and STIA. Notes cover wetland conditions, plant communities (cattail, alder, Juncus, Phalaris, Sparganium, sedge), upland buffer zones, NRM planting plan

This January 2002 transmittal from Parametrix, Inc. to the Washington State Department of Ecology submits corrections to the Seattle-Tacoma International Airport Master Plan Update Natural Resources Mitigation Plan (NRMP, November 2001). The corrections include a revised reference list, an errata sheet fixing citation errors throughout the report, and an updated Table 3.1-4 that adjusts the total acreage of wetlands affected by mitigation activities from 43.34 to 44.36 acres. Additional text corrections clarify wetland category designations and update various reference callouts across multiple sections of the report.
