DESCRIPTION
Relocate a portion of Evans Creek to from an industrial area into open space to reconnect the channel with floodplain wetlands, enhance channel complexity, and restore riparian buffer function.
Redmond proposes to relocate and restore a ditched section of Evans Creek to adjacent open space, enhancing in-stream and riparian habitat for Chinook and Coho salmon. Reach 2 of Evans Creek is currently constricted by industrial development and isolated from its floodplain, with simplified in-stream habitat and no buffers. The project will create a longer more diverse channel with enhanced in-stream structure and habitat, reconnecting the channel with floodplain wetlands. Project enhancements will primarily benefit rearing habitat for Sammamish Chinook (threatened) and Coho (candidate) salmon from Evans and Bear Creeks.
This project will build upon construction of the lower 1,100 feet of channel (currently a backwater) completed by WSDOT in 2013, and additional channel enhancement outside the area proposed for PSAR funding. The PSAR portion of the project will construct 1,200 feet of new channel with in-stream logs and log multi-log structures (proposed PSAR funding and match will support final design, channel creation and in-stream structures).
The project is identified as a high priority in the WRIA 8 Chinook Conservation Plan (N-432A) and by the City.
The overall project will complete creation of 3,500 feet of new creek channel with habitat features, and restore 22 acres of riparian buffer. This work is primarily funded by the City of Redmond stormwater CIP.
