NOTE: This project has been revised to include only the design elements of the original proposal. Alternatives were evaluated and designs prepared to restore complex pool habitat at a historical logjam site, maintain floodplain connectivity, and improve floodplain tributary habitat stability and complexity in the South Fork Nooksack River. The design products were used to inform WRIA 1 salmon recovery partners and the Acme-Van Zandt Flood Control Sub-Zone, facilitate permitting and secure implementation funding. The goal was to produce designs for complex wood structures that would improve mainstem and tributary habitat diversity and complexity and thermal conditions in an area of cool groundwater discharge (Landingstrip Creek). Priority species and life stages include adult and juvenile early chinook salmon and migrating or foraging steelhead and bull trout consistent with the WRIA 1 Salmonid Recovery Plan priorities. The largest land parcel involved (of 4) is owned by Whatcom County to promote floodplain functions and salmon recovery opportunities. The remaining 3 landowners were engaged and supportive of the design process and future project implementation. The Northwest Hydraulic Consultants design team factored in that near-term options to restore channel migration were limited by public infrastructure (i.e., Acme community and water supply well, SR 9, Mosquito Lake Road). The design package produced a design for ballasted structures that will produce near-term improvements to habitat forming processes at the site that will provide direct and immediate benefits to an early chinook salmon stock that is at high risk of extinction. As a separate, but linked action, 8 acres on the County property were reforested under the CREP program during the winter of 2006/2007 to improve riparian and floodplain functions.

1. Prepare up to three conceptual alternatives for a complex log structure or structures along the left bank of the South Fork downstream from "Landingstrip" and extending to the former RV park. Design objectives are to restore pools at historic logjam sites in an area where emergent hyporheic flow contributes to cooler pool temperatures, provide controlled floodplain connectivity, and retard bank retreat and potential capture of an existing floodplain tributary containing high quality juvenile salmonid rearing habitat. 2. Evaluate alternatives for existing riprap. 3. Evaluate hydraulic effects of project alternatives on flood depths and routing using the County's hydraulic model. 4. Select preferred alternative and project designs (70%), supporting documentation suitable for determining construction costs, seeking construction bids, and permitting.
