The Port of Seattle requested $720,000 in Commission authorization to improve the Auburn wetland mitigation site, a nature area created to offset environmental impacts from Sea-Tac Airport's Third Runway construction. The project involves removing roughly 6,171 feet of temporary internal roads, planting approximately 5,000 native trees and shrubs in their place, and installing a new chain-link security fence to stop ongoing trespassing, vandalism, and illegal dumping. These enhancements are required to comply with Clean Water Act permits tied to the 1997 Master Plan Update and are intended to reduce long-term maintenance costs.Open full document
