In June 2022, MOST acquired a conservation easement from The Trust for Public Land on 135 acres of the San Geronimo Commons. The easement permanently protects land along San Geronimo and Larsen Creeks as wildlife habitats and publicly accessible open space. The protected area does not include the 22 acres around the former golf clubhouse and community garden. MOST acquired the easement with more than $3 million in grant funding from the California Wildlife Conservation Board and California Natural Resources Agency. Permanent protection restores the floodplain, enhances Coho salmon and steelhead trout spawning and rearing habitat, conserves water resources, provides the public a network of trails and open space connecting to other preserves, and protects the rural character of the San Geronimo Valley.
