Abstract:

The specific planning objective of this general reevaluation report GRR is to identify the solution to reduce tidal delays for vessels, which transit the access channel between the Small Boat Basin, Citizens Dock, and the existing inner harbor channel. The purpose of this GRR is to determine whether there is a Federal interest in improving navigation in the Citizens Dock and Small Boat Basin access channel in Crescent City Harbor, Del Norte County, California. It was determined the NED National Economic Development plan would be a channel at -14 feet MLLW Mean Lower Low Water, plus one-foot of advanced maintenance and one-foot of overdepth tolerance, with a total volume of 37,700 cubic yards to be dredged. The advanced maintenance would provide shoaling material channel space for a five-year OM cycle. The proposed channel would extend from the present Federally maintained Inner Harbor Channel to the Small Boat Basin. It would vary in width from 140 feet to 210 feet and be 1,200 feet in length. The Benefit-Cost Ratio would be 2.6. The environmental impacts would not be significant. Therefore, an Environmental Assessment and a FONSI Finding of No Significant Impact were prepared.
