DESCRIPTION
The Downey Farmstead Restoration Project is located along the Green River between river mile (RM) 21.5 and RM 22.3. The downstream edge of the site coincides with the confluence of Mullen Slough with the Green River. The site was previously acquired by the City of Kent and this next phase for restoration will create off-channel rearing and refuge habitat for use in the winter and spring months by juvenile salmon, particularly juvenile Chinook salmon, that inhabit the Green River. Enhancing habitat for improved juvenile salmonid rearing, lifestage diversity, and productivity is a priority in the Green River watershed. A secondary goal of the project is to create additional flood storage and to help alleviate flood damages in urban and agricultural areas in the project vicinity. Realignment of Frager RoSavead from near the top of bank and thought the site to the souther portion of the properties is necessary to allow creation of the side channel network and expanded floodplain. The road alignment will provide a greater buffer/setback from the river. The project final design was completed 12/31/13, including the final design report, construction quantities and cost estimate, contract bidding documents and general contract condtions, Cultural Resources Inventory Report, Wetland and Stream Report, Draft Maintenance and Monitoring Report and Adaptive Management Plan, and permit submittals.
City of Kent will restore river processes by constructing a side channel and reconnecting floodplainon the left bank of theGreen River between river mile (RM) 21.5 and RM 22.3. The downstream edge of the site coincides with the confluence of Mullen Slough with the Green River. The site was previously acquired by the City of Kent and this next phase for restoration will create side-channel rearing and refuge habitat for use by juvenile salmon throughout most of the year, particularly juvenile Chinook salmon that inhabit the Green River. Additional fish resources present at the site and expected to utilize the project area are bull trout, chum, coho, cutthroad, pink, winter steelhead, pacific lampreyand river lamprey. Enhancing habitat for improved juvenile salmonid rearing, lifestage diversity, and productivity is a priority in the Green River watershed. A secondary goal of the project is to create additional flood storage and to help alleviate flood damages in urban and agricultural areas in the project vicinity.Frager Road will be relocated away from the river's edge to maximizethe siteto allow creation of the side channel network and expanded floodplain. The road alignment will provide a greater buffer/setback from the river. The project final design was completed 12/31/13, Project #11-1219 andincludesfinal docs and reports.
