Title

Bolinas Lagoon Wye Wetlands Resiliency Project

Description

Marin County Open Space District is proposing to reconstruct the physical and biological linkages between Lewis Gulch Creek and Bolinas Lagoon by realigning Olema Bolinas Road and Lewis Gulch Creek and removing the extension of Fairfax Bolinas Road (Crossover Road). The goal of the proposed project is to restore hydrologic, geomorphic, and ecological processes in the Bolinas Wye wetlands and to restore and improve the resiliency of in stream, tidal wetlands, riparian, and upland habitats with sea level rise and climate change. The project will protect the existing transportation access along Olema Bolinas Road for the town of Bolinas during scenarios consisting of up to 5.5 feet of sea level rise and a 100-year storm event (8 feet combined). Project activities would include realignment of the intersection at Olema Bolinas Road and State Route 1 (SR-1), construction of a new bridge over Lewis Gulch Creek, removal of a section of the Crossover Road that passes through Bolinas Wye wetland, hydrologic restoration of Lewis Gulch Creek, and ecological restoration techniques to supplement bioengineering work conducted for hydrologic restoration.
