DESCRIPTION
Quileute Natural Resources (QNR) developed a Geomorphic Assessment and Action Plan for the Bogachiel River through WCRRI 20-1004P. The highest priority restoration project area was identified at Project Area 3 (PA3) between River Miles 0.75-3.5. QNR has 30% engineering designs for PA3 after the completion of the assessment and seeks funding to advance the engineering designs to 60%.
This project falls under the NPCLE strategy list as project number 2.2.2.3.3.
The Lower Bogachiel Restoration Design (PA-3) project is a planning project seeking to advance engineering designs to the preliminary (60%) design stage, including a risk assessment and proposed conditions hydraulic modeling. PA-3 was the highest priority restoration project to be identified in the Bogachiel River Restoration and Resilience Assessment (WCRRI 20-1004P). PA-3 extends from the State Route 110 bridge upstream to the primary side channel inlet on river left near the confluence with Maxfield Creek (RM 0.75-2.75). The river in this area is dynamic, prone to channel avulsions and rapid channel migration. The 3,000-foot stretch of SR 110 immediately to the east of the bridge is regularly inundated by floodwaters and at risk of severe damage in an avulsion event. The lower Bogachiel River supports all 5 species of salmon and steelhead, but due to anthropogenic impacts suffers from lack or large wood, floodplain disconnection, and warming temperatures. The goals of this project are to advance engineering designs that would increase the quality and quantity of salmon habitat, improve climate resiliency, and improve floodplain connection, as well as to identify options to decrease flood and avulsion risks that threaten SR 110 to present to WSDOT. Throughout the design process, we will utilize a public outreach firm to engage with stakeholders and landowners. PA-3 falls under Projects 2.2.2.3.3 & 2.2.2.3.6 of the North Pacific Coast Lead Entity Recovery Strategy.
