The plan to rearrange the Bolinas wye and restore the surrounding wetlands received a majority of its $11.7 million cost on Tuesday after the Board of Supervisors approved grants from the National Fish and Wildlife Foundation and the Wildlife Conservation Board. Earlier this month, supervisors approved the project and the document confirming it will not result in adverse environmental impacts that cannot be mitigated. The project has four critical elements: the elevation of Olema-Bolinas Road and the development of the new intersection at Highway 1, the installation of a bridge along Olema-Bolinas Road near the intersection, the excavation of a new channel for Lewis Gulch Creek and the removal of invasive species and replanting of natives. The project aims to restore the ecological balance of the area, which was disturbed by the wye and resulting sediment buildup and flooding. In addition to reconnecting the creek to the Bolinas Lagoon, the project will introduce native vegetation that will benefit steelhead trout, red-legged frogs, California black rail and the coho salmon that recently returned to the lagoon. The remainder of the project’s cost will be funded by various organizations, including $1.3 million from Measure A and $2 million from the America Rescue Plan Act. The vegetation plan reflects the diverse ecology of the area. Species like saltgrass and pickleweed will be placed in marshy areas, while in areas dominated by coast live oak and coyote brush, species like soaproot, wild cucumber, sticky monkey flower and wild strawberry will be planted. Max Korten, director of Marin County Parks, said the removal of invasive Cape ivy will be the first step to prevent unwanted rhizomes from spreading during the excavation process set to begin next summer.
