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. In 2024, additional work provided 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 2024, with planting and restoration scheduled for 2025.

The Fish Camp Project Area is located in the lower South Fork Nooksack River valley downstream and upstream of the town of Acme between river mile (RM) 7.3 and RM 9.7, respectively. The Project Area includes the SFNR mainstem channel and floodplain habitats and extends from the end of Rothenbuhler Rd. in the south to just downstream of the BNSF railway bridge in the north. The State Route (SR) 9 bridge crosses over the SFNR near RM 8.6 and conveniently separates the project area into upstream (Phase 2) and downstream (Phase 1) sections. Project Status: Design and log Procurement in 2025, Phase 1 Construction in 2026, Phase 2 Construction (incl Berms) in 2027 Total Estimated Cost: $3,340,000 Expenditures to Date: $11,000 31 Whatcom County Public Works — River and Flood Division Project Narrative Floodplain Acquisition Database ID No. 07-002 Acquisition Funding Years : 2017- TBD Project Narrative: 2025-2030 Six -Year WRIP Item No. 32 Reach -scale projects to reconfigure f►ood infrastructure are being evaluated through the integrated planning processes that started with the System -wide Improvement Framework (SWIF) and has transitioned into the Floodplain Integrated Planning (FLIP) process. The goal of this work is to reduce flood risk and expenditures and restore habitat and the processes that form it. Voluntary acquisition of lands is proposed to enable future levee reconfigurations to reduce flood risk and future levee repairs, while improving habitat. Project Status: Acquisition of 12 properties and demolition of associated structures occurred in 2024 and additional acquisitions and demolitions are anticipated in 2025. Acquisitions are targeted in areas that sustained significant damage in 2021, in areas mapped as FEMA floodways and areas that will enable future flood hazard reduction projects Total Estimated Cost: N/A Expenditures to Date: N/A 32 Whatcom County Public Works — River and Flood Division 2025-2030 Six -Year WRIP Project Narrative Item No. 33 Marietta Acquisition Database ID No. 07-002 Construction Funding Years : 2001 - Present Project Narrative: Acquisition of residential properties in the frequently -flooded repetitive flood loss area of Marietta, removal of existing structures and restoration of properties with native vegetation. Project Status: Property acquisition began in 2001 and is ongoing. As properties are acquired, structures are removed and native vegetation is planted. All acquisitions are voluntary and the project is ongoing as current property owners decide to sell their properties. Total project cost will need to include funding for cleanup of up to four former gas stations, though the exact nature of the work is still undefined.

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 2025 clean out is anticipated to be complete in September 2025 for a cost of $100,000. Total Estimated Cost is for annual estimated cleanout costs funded by the FCZD. Total Estimated Cost: approximately $120,000 annually Expenditures to Date: -- 34 Whatcom County Public Works — River and Flood Division 2025-2030 Six -Year WRIP Project Narrative Item No. 35 Emergency/New Projects Database ID No. 08-003 Construction Funding Years : 2025 - 2030 Project Narrative: This item provides funding to address unanticipated projects resulting from new damage to flood control facilities.
