Tide's End Multibenefit Restoration Project

The Tide's End Multibenefit Restoration Project, managed by the California Department of Water Resources Division of Multibenefit Initiatives, aims to restore tidal wetland and floodplain habitats in the Yolo Bypass near Dixon, California. The project focuses on enhancing aquatic production and fish passage for juvenile salmonids and other native species by hydrologically connecting the site to the Toe Drain through berm openings, lowering, and channel excavation. The scope of work includes the development of tidal wetlands, transition zones, managed wetlands, floodplain agriculture, and riparian revegetation, alongside necessary irrigation, drainage, and access improvements. Technical execution requires adherence to the International Building Code and Delta Plan Policies, with specific mandates for geotechnical reports analyzing seismic loading and expansive clay. Environmental compliance is stringent, requiring the use of low ground-pressure equipment, daily fluid leakage inspections, and strict decontamination protocols to prevent the spread of aquatic invasive species. Biological protections include the presence of approved biologists during vegetation clearing, prohibitions on synthetic sediment control products, and a 20 mph speed limit on unpaved roads. Success for revegetated areas is defined as achieving at least 60 percent absolute cover compared to pre-project or reference conditions, with a minimum two-year monitoring period. Project oversight includes the authority of resource specialists to halt work for permit non-compliance and the requirement for the project proponent to provide annual monitoring reports.
