This project was initiated with the washout of Upper Hoh Road between MP 7.8 and MP 8.0 during a high flow event in the Hoh River in December, 2007. The project consisted of an emergency repair of Upper Hoh Road MP 7.7-8.0 by construction of a riprap revetment, road reconstruction, paving, and guardrail. This work was completed in 2008. The Washington Dept. of Fish and Wildlife required environmental mitigation for the emergency repair, which was satisfied by replacing the culvert at Upper Hoh Road MP 2.15 (Alder Creek Tributary) with a fish-passable structure, which was completed in 2013.

As described above, Upper Hoh Road MP 7.7-8.0 was reconstructed following the washout in 2007. To satisfy environmental mitigation for the repair, the culvert at Upper Hoh Road MP 2.15 (Alder Creek Tributary) was replaced with a fish-passable structure, completed in 2013.
