Bothin Marsh
Adaptation Project 

Bothin Marsh Open Space Preserve: connecting Marin County to the importance of its most visited and most vulnerable open space park. 

Rising sea levels are threatening the Preserve’s shoreline habitats and their ability to support abundant native wildlife, including special-status species, migratory birds, and rare plant species. A critical, existing transportation and recreation link along the Mill Valley/Sausalito Multi-use Path in the Preserve floods over 30 times each year and will only worsen with impending sea level rise. Through the Bothin Marsh Adaptation Project, WRT and team developed conceptual designs to adapt the Preserve to changing climate and rising seas. Nature-based strategies allow for the evolution and restoration of tidal wetlands and the restoration of ecological processes and habitat function at Bothin Marsh.
