An existing armored revetment owned and maintained by Pierce County within Mount Rainier National Park (MRNP) suffers repetitive severe flood damages during moderate to high flow events. Repairs to the revetment are very costly and continue to mount. Improvements include installing energy dissipating structures along the face of the existing levee.
This Pierce County Planning and Public Works project will reduce flood risk and annual maintenance against the levee in the upper Nisqually near the MRNP entrance area at SR 706.
The levee will be closed to recreational use as well as the river in the work areas. Improvements will be constructed from June 2021- October 2021.
Pierce County staff is available to discuss this project.
