Document Description
The proposed project includes excavation of approximately 70 cubic yards of gravel and construction of a 16-foot x 14-foot x 13-foot concrete vault at the outlet of an existing pipeline at the base of Phoenix dam; the vault will extend approximately 4 feet above streambed grade. Concrete piers, drilled 18 inches into the surrounding area, will support the vault and the refurbished outlet pipe will be fitted with a 30-inch butterfly valve in order to facilitate CA Division of Dam safety requirements to exercise the outlet valve annually. The applicant plans to offset project impacts by placing 10 cubic yards of clean river-washed gravel, grade 1 to 4 inches, in the streambed so that it can mobilize downstream during large flow events to replenish downstream salmonid spawning substrate. Heavy machinery, including excavators, a drill rig and other large equipment shall enter the creek during construction. The project site is located within and around the riparian and streambed and bank zone of Ross Creek at the base of Phoenix dam in the town of Ross, Marin County of the San Rafael 7.5 minute U.S. Geological Survey quadrangle. The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement number 1600-2007-0319-3 pursuant to Section 1602 of the Fish and Game Code to the project operator, Eric McGuire.
