Bolinas Lagoon-South End Restoration Project

Bolinas Lagoon is a nationally significant estuary within Greater Farallones National Marine Sanctuary. The South End Restoration Project focuses on restoring tidal marsh and lagoon-edge habitats at the southernmost reach of the Lagoon, an area facing ecological stress from invasive species, altered shoreline conditions, and increasing flood risk due to sea level rise.

Led jointly by Greater Farallones and Cordell Bank National Marine Sanctuaries and the Greater Farallones Association, in collaboration with Marin County and the Seadrift Association, this project aims to restore natural coastal features that support both ecological health and coastal resilience.

The south end of Bolinas Lagoon includes the last long stretch of undeveloped shoreline in the estuary. The project area provides critical habitat for migratory birds, native plants, and estuarine species, while also buffering low-lying areas from rising water levels. Restoration goals include removing invasive plants, enhancing habitat diversity, and re-establishing features such as tidal marshes, swales, and backdune terraces to help the shoreline adapt to future change.

The project is currently in its feasibility and design phase. Ongoing work includes scientific assessments, modeling, conceptual design development, and engagement with local partners and stakeholders. Environmental compliance and permitting will follow.

This effort reflects the sanctuary’s commitment to restoring natural processes, supporting habitat recovery, and fostering partnerships to protect coastal resources. The project builds on recommendations from the 2008 Bolinas Lagoon Ecosystem Restoration Project Local Coastal Program Amendment and aligns with the sanctuary’s coastal resilience objectives.
