Document Description
The California Department of fish and Fame (the Department) is issued Streambed Alteration Agreement (Agreement) to the California Department of Transportation (Caltrans) for the project described herein (the Project). The Project is located on state Route (SR) 1 in Santa Cruz County at postmile 34.49, approximately 5 miles north of the community of Davenport, and approximately 7 miles north of the City of Santa Cruz. The project will replace an existing corroded 223-foot long, 18-inch in diameter, corrugated metal pipe culvert that conveys an unnamed ephemeral drainage (non-fish bearing) under SR 1. The existing pipe will be backfilled with clean sand and abandoned in place and the existing headwall will be removed. The new pipe will be a reinforced concrete pipe measuring 250-feet long and 26-inches in diameter. The new pipe will be jacked in from a temporary jack pit (30X12 feet) that will be located on the east side of SR 1. No water diversion will be required as the existing pipe can convey flows until the new pipe is installed. No tress will be removed. A new headwall (12 feet long, 4.6 feet tall) and debris rack (4-feet tall) will be installed at the new inlet. Gabion baskets (88.3 cubic yards, 1400 square feet) will be placed at the outlet to dissipated energy and reduce erosion. Additionally, slurry cement backfill (11 cubic feet) will be placed around the pipe outlet, between the pipe and the gabion baskets. The slurry cement will help anchor down the end of the pipe and reduce the possibility of the last section of pipe sliding due to gravity or high speed/volume water. Equipment needs will include hacking equipment, a crane or broom truck, and a small excavator. Issuance of a Streambed Alteration Agreement Number 1600-2008-0386-3 is pursuant to Fish and Game Code Section 1602.
