One of the pipes drains a channel that flows through the City of Lynden's wastewater treatment plant. The levee has overtopped where the culverts are located, damaging the levee backslope and the small berm that separates the drainage channel from a water treatment settling pond. The conceptual design developed as part of the System -wide Improvement Framework (SWIF) planning process includes relocating the treatment plant drainage channel through a forested area further away from the pond, connecting the two drainages, and replacing the two culverts with a single larger fish -passable culvert with a side -hinge flood gate. Project This project is being implemented collaboratively by the FCZD and the USACE. The culvert replacement and levee improvement are being designed by the USACE as part of a levee rehabilitation project. The County is currently at a 60% design level for the reconfigured drainage channel behind the levee. Construction for both portions of this job is expected in 2021.

Approximately 250 feet of the levee running along Cougar Creek is over -steepened and experiencing sloughing of the riverward face. A stabilization project incorporating large woody debris at the toe and reducing the slope of the riverward face is proposed in the System -wide Improvement Framework (SWIF) to resolve the deficiency identified by the US Army Corps of Engineers and keep the levee eligible for repair under the Public Law (PL) 84-99 Program. An early action project developed through the Floodplain Integrated Planning (FLIP) process includes replacement of the Cougar Creek flood gate and installation of large woody debris in the channel downstream.

Baker Highway (SR 542). During high-water events of the 2017/2018 winter, the North Fork Nooksack River eroded the unprotected bank of Truck Road to within 13 feet of the roadway surface. This prompted an emergency project to construct a passive riprap revetment underneath a section of the roadway to provide immediate protection. Flooding during 2020 eroded the remaining bank exposing the recently constructed riprap revetment and destabilizing a portion of the north bound lane. Jersey barriers were placed by county crews to block off this lane to traffic. The FCZD is evaluating road realignment and bank stabilization alternatives to provide a long-term solution in this area. Project Status: An analysis of road realignment and bank stabilization alternatives is planned for 2021. Preliminary design of the preferred alternatives will be initiated once the preferred alternative is selected. Construction of the road setback is anticipated to occur in 2023.

Since construction, the levee has been subject to ongoing damage. Constriction of the Glacier -Gallup channel migration zone (CMZ) has exacerbated aggradation upstream of SR 542 and severely degraded fish habitat. WSDOT replaced the Gallup Creek bridge and is working to construct a new bridge over Glacier Creek and the alluvial fan between the two creeks. The FCZD is developing a project in coordination with WSDOT and is evaluating the feasibility of full or partial removal of levees blocking natural channel migration on the Glacier and Gallup Creeks alluvial fan and construction of a setback levee on Gallup Creek to protect the Community of Glacier. Project Status: A feasibility study and alternatives analysis for evaluating levee removal and setback alternatives was initiated in late 2018.
