This project is a critical element in restoration of the Dungeness River, including the lower river, the delta/estuary, and Dungeness Bay. Schoolhouse Bridge was constructed in 1964 with an appropriate width to accommodate existing Corps levees. Since then, the effect of the levees on the river, especially the spawning areas for the lower river Pink salmon (a critical species under the SASSI report) and estuarine habitat for rearing/feeding of other species of salmon, has been dramatic. Available stream energy in the diked reach has increased channel instability to the point where spawning success is near zero. Also, increased sediment transport and decreased sediment storage capacity in the reduced floodplain has led to aggradation of the streambed, dramatic alterations of the delta, and increased rates of sediment accumulation in Dungeness Bay. The "shallowing" of the Bay has reduced tidal flushing, changed shore dynamics, and lowered water quality. Clallam County requested the Corps to reexamine the location of the levees and concurs with the above assessment. To begin the analysis of changing the existing levees, the Corps requires the County to make a commitment to replace/alter the existing bridge. Upon commitment, the Corps can begin scoping and design for restoration of the lower river. This project is to study the bridge in terms of flood conveyance, natural river function, sediment transport, and geotechnical feasibility. Some data is already available.
