EXH 335: Declaration James C. Kelley PhD — Wetland Impacts Mitigation STIA Master Plan Update PCHB 01-133

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.
