Section 107 Detailed Project Report. Fort Gaines Channel (Government Cut) at Dauphin Island, Alabama

Abstract

This report consists of an economic environmental analysis for Fort Gaines Channel Improvement at Dauphin Island, AL. The recommended plan provides for deepening the existing channel to 6 feet plus 2 feet advance maintenance dredging and 1-foot allowable overdepth. The new work dredged material would be approximately 17,258 cubic yards of sandy material and would be disposed of on a beach nourishment site located on Dauphin Island. Construction of the recommended plan is estimated to cost $143,200. Of this amount the federal cost would be $114,600 and the non-Federal cost would be $28,600. The plan has an average annual cost of $19,000 and benefits of $20,000 which provide a benefit- to-cost ratio of 1.1.
