A Conditional Use Permit for the Martin Slough Enhancement Project (MSEP), an estuary enhancement project. Work will occur in both the unincorporated area and inside the City of Eureka in up to six or more phases depending on available funding. Phase 1, the tide gate replacement, occurred in 2014. The applicant’s Project Description dated June 2016 provides phasing details. The project involves excavation of approximately 3,050 feet of the main channel of Martin Slough and approximately 1,300 feet of an old meander channel to remove accumulated sediment, and increase floodwater and tide water conveyance through the project area; excavation of a stream channel to daylight and reconnect a section of a tributary creek; construction and enlargement of tidal and freshwater wetlands to increase floodwater storage and provide enhanced fisheries and waterfowl habitat. All phases include placement of large wooden structures to enhance habitat, installation and removal of fish exclusion screens, fish capture and relocation, installation and removal of coffer dams, installation of stream bypass equipment, improvements to existing drainage infrastructure, installation of erosion control measures, and revegetation. Excavation will result in a total of approximately 65,000 cubic yards of sediment, of which approximately 55,000 cubic yards will be hauled offsite to White Slough in the Humboldt Bay National Wildlife Refuge or another approved location. The remaining approximately 10,000 cubic yards of excavated sediment is to be used in the project area to fill low spots in pasturelands and in the City of Eureka Municipal golf course to create positive drainage to prevent ponding on the floodplain and fish stranding during flood...
