George Will writes in his column today about the importance of the Port of Charleston – and by extension, trade – to the economy of South Carolina. Recent completion of the 10-year project to widen the Panama Canal to accommodate more traffic and passage of a new class of container ships with nearly triple the capacity of their immediate predecessors has exposed a logistics snafu that could cost South Carolina’s economy billions of dollars: Charleston Harbor is too shallow to accommodate these much larger, “Post-Panamax” ships efficiently (only limited sections of the harbor are deep enough and only during high tide).
According to the American Society of Civil Engineers, these vessels can lower shipping costs from 15-20 percent, but harbors need to be at least 47 feet deep to accommodate them. The U.S. Army Corps of Engineers reports that only seven of the 44 major U.S. Gulf Coast and Atlantic ports are “Post-Panamax ready.” American ports must be modernized if the United States is going to continue to succeed at attracting investment in manufacturing and if U.S. companies are going to compete successfully in the global economy.
As I wrote in the Wall Street Journal last year:
The absence of suitable harbors, especially in the fast-growing Southeast, means fewer infrastructure- and business-development projects to undergird regional growth. It also means that Post-Panamax ships will have to continue calling on West Coast ports, where their containers will be put on trucks and railcars to get products from Asia to the U.S. East and Midwest—a slower and more expensive process.
The problem can be traced to one major issue: funding. And that issue is made more complicated by another problem: protectionism. Most funding of infrastructure inevitably come from federal and state budgets – taxpayers, who should have a voice in the debate about whether these infrastructure projects constitute wise public investments. But a couple of long-standing, though obscure, protectionist laws have conspired to reduce capacity in dredging services, ensuring that projects take twice as long and cost twice as much as they should.
