SR 410 Install Interim Flood Protection Measures Along Mather Memorial Parkway

Mount Rainier National Park » SR 410 Install Interim Flood Protection Measures Along Mather Memorial Parkway » Document List

Mount Rainier National Park Superintendent Randy King has announced that the park is initiating the preparation of an Environmental Assessment (EA) for the installation of flood mitigation structures within the White River corridor to protect State Route 410, also known as the Mather Memorial Parkway, a national scenic byway and contributing element to the park National Historic Landmark District. It is also the primary eastern access to Mount Rainier National Park. In accordance with the National Environmental Policy Act (NEPA), the EA will present alternatives for the work and analyze and disclose potential environmental impacts.

The project area includes the White River and SR 410 between milepost 57.9 and milepost 60.0. Proposed activities include the installation of structures, such as buried log and rock toes, log debris walls, headcut log fills, and engineered log jams at strategic locations in the White River floodplain to provide flood protection for the road. The structures are constructed of logs and ballast rock engineered to act as a single unit.
