Listen to our recorded June 8 presentation, "Evolving Shorelines Community Meeting: Concepts Evaluation Presentation" here>>
Bothin Marsh is a well-loved stretch of shoreline that offers much in the way of recreation and wildlife, with unique plants and animals surrounded by urban development. With climate change and sea level rise, flooding is increasing in frequency and duration on the Mill Valley-Sausalito Multi-Use Path (Bay Trail) and throughout Bothin Marsh.
Bothin Marsh’s natural resources provide numerous ecological, economic, and social benefits to human visitors and neighbors. The land managers of Bothin Marsh Open Space Preserve have the responsibility of protecting an ecologically rich and beloved open space and recreational access. Bothin Marsh will likely see ten inches of sea level rise by the year 2030. One Tam, with community partners and community members, is urgently working to adapt the marsh ecosystem and the Bay Trail to sea level rise. Easily accessible and highly visible, Bothin Marsh is uniquely positioned to model how innovative, nature-based techniques can support the adaptation of this area and be applied elsewhere in our communities and throughout the Bay Area.

One Tam partners – the Golden Gate National Parks Conservancy and Marin County Parks – are working together on the Evolving Shorelines Project at Bothin Marsh.
The Parks Conservancy provides support through fundraising, community engagement, communications and co-project management for this project. Bothin Marsh lies within the jurisdiction of Marin County Parks, land managers of this Open Space Preserve.
Restoration work at Bothin Marsh is primarily funded by Marin County Measure A. Past project funding has been provided by the California State Coastal Conservancy, the Marin Community Foundation, and generous support from One Tam members.
