Restoring a Source of Healing

Tolay Lake Regional Park Master Plan

Rich in prehistoric and natural resources, Tolay Lake is a precious cultural resource and a source of healing for the Federated Indians of the Graton Rancheria (FIGR). MIG is preparing a Master Plan and EIR for 3,434-acre Tolay Lake Regional Park, which features multiple trails, historic buildings, a working farm, a seasonal lake, and a creek that flows to San Pablo Bay. The park is the largest in the Regional Parks’ system and provides critical watershed and habitat protections, especially for bird populations. 

The Master Plan will help determine appropriate recreational uses and level of development for this unique property and adjoining Sonoma Land Trust property, which is slated to become part of the Park. We’re conducting several technical studies to support development of the Master Plan: a historic structures study, cultural landscape study, groundwater availability study and a biological resources study. Significant issues noise and traffic impacts on neighboring properties, restoring Tolay Lake to flood those properties; and potential impacts of park development on biological, prehistoric and historic resources. After completing the technical studies and Master Plan, MIG will prepare the EIR.
