A watershed greenbelt spans the valley floor.
San Geronimo Park, which includes San Geronimo Meadow and Larson Meadow, is managed by Marin County Parks. The park has significant conservation value. Marin Open Space Trust (MOST) holds a conservation easement on the property that governs use to protect natural conditions and features. The easement allows enhanced streamflows and water quality, fire resilience, and low-impact recreation such as hiking, biking, horseback riding, and safe routes to school. The conservation easement does not allow recreational activities and facilities that would have a significant impact on the natural environment.
San Geronimo Commons is managed by the Marin County Fire Department. This includes the clubhouse, community garden, parking lot, and the meadow below. The Commons will be the home of a new fire station, and remains a community hub space. It offers an excellent place to park when visiting San Geronimo Park and surrounding Marin County Open Space District preserves.
