It is recommended that maintenance dredging in Georgetown Harbor be performed at 6-month intervals. Dredging depth would be 29 feet from the outer bar in the Atlantic ocean to Station 890OO. Maintenance would be performed in this reach on an annual basis except for the reach between Stations 72000 to 79000 which would be on a biannual basis. Dredging depth would be 31 feet from Station 89000 to the Georgetown turning basin including the side channel, with maintenance being performed on a biannual basis. Implementation of the plan would be at an estimated first cost to the Federal government of 1,058,400 for new work. Annual maintenance costs would increase 309,000, yielding a total annual maintenance cost of 1,339,000. Implementation of the plan would be contingent upon the sponsors ability to provide a minimum of an additional 400 acres of suitable disposal areas. It is further recommended that implementation of the above be expedited as the future development of this harbor and the economic potential of the area will be affected.
