Marin County plans to reroute a Bolinas Lagoon creek as part of an effort to prevent flooding along Highway 1, prepare for sea-level rise and restore habitat for threatened species. The county’s Bolinas Lagoon Wye Wetlands Project aims to redirect Lewis Gulch Creek closer to its historic route and raise a nearby road to allow the creek more room to wind and flow during winter storms. The project would also restore floodplains at the northern end of the 1,100-acre Bolinas Lagoon that were lost over more than a century as wetlands made way for roads and pastures.
