DESCRIPTION
The Lower Tolt River Floodplain Reconnection Project will restore connectivity between the Tolt River and 48 acres of floodplain habitat on County-owned land. King County and the City of Seattle propose to remove the existing right bank levee that extends a ½ mile from SR 203 to the confluence with the Snoqualmie River and construct a set back levee approximately 800 feet behind the existing levee. This will permanently restore the river's natural floodplain processes in this reach, allowing it to migrate and access its floodplain in high flows. The outcome will be greater and more complex habitat quantity and quality for Chinook salmon, Steelhead trout, and other salmonids that utilize the Tolt River. This project is a high priority salmon recovery project in the Snohomish River Basin Salmon Conservation Plan. The project proponents have already received grant funding from the Salmon Recovery Funding Board, King Conservation District, NOAA and the Aquatic Lands Enhancement Account, in addition to a significant contribution of local funds from both partners. The project partners are now completing the final design and the permitting process and crafting an intergovernmental agreement for project completion. Construction is planned to begin in mid-2008.
