Jan 30, 2012 - Charleston's harbor pilots and docking pilots worked with the Army Corps of Engineers last week for a tabletop exercise to examine the current shipping channel and turning basins as part of the Corps study of the potential of deepening the Port of Charleston to 50 feet, even at low tide.
The expertise of the harbor pilots on how big ships move through Charleston Harbor will help the Corps narrow its alternatives that will be simulated as part of what is called Charleston’s Post-45 feasibility study.
"It's one of those things we think will allow us to do the study smarter, better and faster," Brian Williams, the Corps' project manager, told the Associated Press. By engaging the pilots earlier in the study process, "we're saving ourselves time and money by weeding things out," he said.
The Charleston deepening is projected to cost $300 million, versus costs in excess of $650 million to deepen the Savannah River, and both ports authorities are in a stiff political battle to win Congressional approval of one plan versus the other.
In the Charleston scenario, the federal government would pay $120 million, and South Carolina taxpayers would pay $180 million. Deepening the Charleston port is projected to return $100 million a year to the state.
Currently, Charleston maintains a harbor of 45 feet (13.7 meters) of depth at mean low tide throughout the main shipping channel and -47 feet (14.3 m) in the entrance channel. A five to six foot tidal lift provides even deeper access for several hours during the day.
In addition to having deep water now, the Port of Charleston is advancing a next-generation harbor deepening project. The U.S. Army Corps of Engineers completed the project's reconnaissance study in the summer of 2010 and determined that there is not only a federal interest in the further deepening of Charleston Harbor, but also that it was most likely the best value for scarce public dollars, according to the Charleston Ports Authority.
The project is currently in the feasibility phase, with a commitment from the Corps to an accelerated time frame.
The Charleston Ports Authority has voted to provide an additional $2 million to the Corps for ongoing work in fiscal year 2012. The total study is projected to cost $18- to 20-million, funded 50/50 by the Corps and the South Carolina Ports Authority
