ASHFORD, Wash. - The National Park Service is seeking public comments regarding a proposed project by Pierce County to retrofit the upper Nisqually River levee in Mount Rainier National Park with deflectors. The 21-day comment period closes on July 9, 2018.
Currently Pierce County has a right-of-way with the National Park Service that grants permission to the county for the construction, operation and maintenance of the upper Nisqually River revetment, also referred to as the levee. The purpose of the proposed deflector project is to reduce erosion and reoccurring levee damage by reducing adjacent water velocity and shifting the main channel away from the levee and toward the center of the floodplain. The county proposes to add large wood to at least half of the deflectors, which would increase roughness and add habitat complexity to the existing levee face. The project is expected to reduce long-term maintenance costs of the nearly one-mile long flood control levee.
The proposed work would occur during the summer of 2019.
Pierce County originally constructed the levee in 1961 between river mile (RM) 64.5 upstream to RM 65.4. About one half of the levee is located within the park. The levee protects the historic Nisqually Entrance and the Nisqually to Paradise Road within the park, and the residential community and businesses located immediately west of the park boundary.
The levee was heavily damaged during the November 2006 flood event, which closed the Nisqually to Paradise Road and destroyed the Sunshine Point Campground. The U.S. Army Corps of Engineers and Pierce County have repaired the levee four times since 2006.
