One Tam: many ways to give back to the mountain that gives us so much

Bothin Marsh

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 in the next ten years. One Tam, with community partners and community members, is urgently working to adapt the marsh ecosystem and the Mill Valley/Sausalito Multi-use Path 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.

Project Leadership

One Tam partners – The Golden Gate National Parks Conservancy and Marin County Parks – are working together on the Bothin Marsh project.

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 Measure A.

The conceptual design of the Evolving Shorelines project is partially funded by the California State Coastal Conservancy and the Marin Community Foundation through the Advancing Nature-Based Adaptation Solutions grant program. This program seeks to support nature-based approaches that address the risks and impacts of climate change and sea level rise to protect the Marin County bay and coastal shorelines and natural resources.

The Coastal Conservancy is a California state agency, established in 1976, to protect and improve natural lands and waterways, to help people get to and enjoy the outdoors, and to sustain local economies along California’s coast. It acts with others to protect and restore, and increase public access to, California’s coast, ocean, coastal watersheds, and the San Francisco Bay Area. Its vision is of a beautiful, restored, and accessible coast for current and future generations of Californians. For more information please visit
