Document Description
Pursuant to Fish and Game Code section 1652, the California Department of Fish and Wildlife has approved the Potrero Creek Fish Passage and Lower Culvert Project submitted by Paul Robins, Executive Director of the Resource Conservation District of Monterey County. Implementation of the Project will involve removal, salvage, and replanting of two arroyo willows (Salix lasiolepi) and one California buckeye (Aesculus californica). Approximately 1,670 square feet of asphalt roadway, 100 linear feet of AC dike, and 210 square feet of concrete rubble will be demolished. Electrical, gas, and water lines will be removed and relocated. The Project will also include the removal of an existing 100-foot-long, 54-inch diameter steel pipe culvert, located under an access road, and replace it with a 107.9-foot-long, 12-foot-10-inch span by 8 foot-4-inch rise multiplate arched culvert, embedded 24-30 inches below channel grade and backfilled with approximately 166 cubic yards (CY) of engineered streambed material to maintain habitat consistency with adjoining reaches of the channel. A collar will be formed around the inlet and outlet of the arched culvert with approximately 12 CY of concrete. An approximately 144 CY of rock slope protection will be installed at the inlet of the new culvert where channel banks are steepest and along the river right bank. 30 linear feet of 12-inch diameter and 19 linear feet of 6-inch diameter watertight pipe will be installed at the driveway curb on the downstream end to allow for roadway drainage. Following installation of the new culvert, approximately 1,670 square feet (16 CY) of asphalt road will be paved over the crossing to restore site access. A native seed mix will be spread within disturbed areas to stabilize graded streambanks. The Project will result in approximately 148 linear feet of restored streambed.
