Tolay Lake Regional Park Master Plan
What & Why?
Sonoma County Regional Parks has established a long-term vision for Tolay Lake Regional Park through a comprehensive master planning process. This plan serves as a roadmap to expand outdoor recreation and environmental education while ensuring the rigorous protection for the park’s sensitive natural habitats, cultural landscapes, and agricultural heritage. Following approval by the Board of Supervisors on October 9, 2018, the park officially opened for daily public access. Improvements, including the paving of Cannon Lane, have been completed to enhance visitors’ use.
This important work was achieved through the partnership of the Federated Indians of Graton Rancheria, Sonoma Land Trust, and Sonoma County Agricultural Preservation and Open Space District.
What's Next?
Regional Parks continues to pursue state and local funding opportunities to bring the vision to life. The first element of the master plan buildout, the construction of the Gathering Area, a celebration and event space, will be completed later this year. Additional phases of the master plan will be implemented as funding becomes available.
