Title
Pine Mountain Tunnel Tanks Project
Description
Constructed in the late 1910s to convey water from Alpine Reservoir to Fairfax and San Rafael, Pine Mountain Tunnel was converted to a water storage facility in 1971 and remains in that use today. Marin Water proposes to cease using the Pine Mountain Tunnel for water storage, and to replace the existing storage by building two, 2-million-gallon concrete water storage tanks on Marin Water's watershed property. The tanks would be connected to an existing 30-inch pipeline in Concrete Pipe Road with minimal piping interconnecting the tanks. No Project-related activity is anticipated at the Pine Mountain Tunnel site, other than draining the Tunnel when the replacement tanks have been commissioned and are in use.
