Upper Hoh River Emergency Repair
Upper Hoh River road washed out in November 2016 during a high water event. The washout damaged approximately 250 linear feet of road at approximately milepost (MP) 17, just short of the Visitor Center and Ranger Station. The Park, in response to the washout, placed riprap along the bank to preserve the remaining portion of road.

Scope of Work
The design will consist of placing log/riprap measures in the river as a permanent structure – replacing and/or working with the existing riprap that was placed after the high water event. The structure will allow the roadway to be rebuilt as a paved two-lane road. In this area there is one pipe that will need to be replaced. The road will be closed for four weeks to complete the work.
Park will supply logs and/or root wads to be that need to be included in the permanent repair. They are stockpiled and available at the Elwha pit along Olympic Hot Springs Road.
