Summary
Project Description
The Project consists of three trail improvement elements at the Marin Council of the Boy Scouts of America’s (MCBSA) Camp Tamarancho facility, located in unincorporated Marin County adjacent to the Town of Fairfax. The three trail improvements are proposed as part of the Project and are all addressed in the environmental review document. The trail improvements would be integrated into the facility’s existing trail system. Two of these trail segments, along the Lower Caballo Rojo Trail and Broken Dam Trail, are proposed by the MCBSA; the third trail segment improvement, along the Saddlecut Road to Trail, is proposed by the Marin County Parks and Open Space District. Marin County Planning is the Lead Agency for the Project and these trail improvements are proposed to improve safety and provide erosion reduction.
