Truck Road Bank Stabilization
Database ID No. 20-003
Construction Funding Years : 2023
Project Narrative:
The project is located along Truck Road about 0.3 miles easterly from Mt. 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. Additional erosion sustained the November 2021 floods, threatened the road
downstream of the previous damage area. The FCZD undertook an emergency project to address the immediate threat to
truck road. Additional work is needed to provide environmental mitigation for that action and to repair and realign the
damaged section of road.
Project Status:
The FCZD has completed the emergency repair and is currently designing and permitting the associated Phase 2 project
that will provide environmental mitigation and road repair. Construction of the Phase 2 project is anticipated to occur in
2023. The FCZD anticipates that FEMA and the State will fund 95% of the project through the Public Disaster Assistance
program

Glacier -Gallup Creeks Alluvial Fan Restoration
Database ID No. 18-006
Construction Funding Years : 2023, 2027
Project Narrative:
The Glacier Creek Levee on the left (west) bank of the creek was constructed in the 1960s to prevent
overflows into Gallup Creek and damage to State Route (SR) 542. 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. Preliminary design of the preferred alternative will be initiated once the preferred alternative is
selected. Construction of an interim project to address levee damage is anticipated in 2023. Construction of the
levee removal and setback is anticipated to occur concurrently with the Glacier Creek bridge replacement in
2027.

High Creek Sediment Trap
Database ID No. 22-005
Construction Funding Years : Annually
Project Narrative:
High Creek flooding damaged nearby homes and closed Mount Baker Highway in the mid-1990's. A legal settlement
resulting from that event directs Whatcom County to prepare a creek management plan. Sediment management in the
watershed including the 3400 feet of County owned right of way east of Kendall Creek is an important plan element along
with fish habitat mitigation. State permits for future maintenance dredging are dependent on consistency with the final
management plan. A management plan was developed and recommended the construction of two sediment traps, one
sited upstream of Mount Baker Highway to trap coarser material and one by the confluence with Kendall Creek to trap
finer material. The sediment traps were constructed in 2018. The project provides for the annual clean out of those
sediment traps.
Project Status:
The 2022 clean out was be funded at 95% through the FEMA Public Disaster Assistance grant. Future cleanouts are
anticipated to be funded by FCZD. Total Estimated Cost is for annual estimated cleanout costs.
