While most Americans celebrated Labor Day, got their children ready for school, or followed-up on a promise to spend one more weekend camping with the family in the great outdoors, the people of New Orleans evacuated their city and prayed for a safe return home. Hurricane Gustav made landfall about 70 miles southwest of New Orleans near Cocodrie, Louisiana. The storm weakened to a Category 2 hurricane before making landfall and degraded to a tropical storm shortly afterward, but what was the cost of this storm that almost devastated New Orleans?
Can we keep building-up a city and key port while the great Mississippi River wants to redirect itself? Is it a best-case scenario to let ruins wash away into the Gulf of Mexico? The cost of the infrastructure that redirects the Mississippi River has risen to new levels as the Army Corps of Engineers prepares for the worst-case scenario. Levees need to be designed to withstand forecasted Category 5 storm surges. Careful calculations are being made as existing levees subside and fluvial deposits accumulate.
The all-important river ways, like the MRGO (Mississippi River Gulf Outlet), are being dredged year in and year out as fluvial deposits accumulate and freshwater marshes dissipate, amplifying the problem. Now that legislation will close the MRGO, and a replacement may not be completed for some time, what is the value of rebuilding infrastructure? Does it make sense to build a ship lock capable of accommodating deep-draft ocean-going vessels in the Industrial Canal? Can we relocate the inner harbor near the mouth of the Great Mississippi? Will government re-evaluate the economic value of the man-made waterways? Where and when will the most valuable port in the Gulf of Mexico and possibly the Eastern seashore get relocated?
