Raise New Orleans Ground Level LIke Galveston Did
New Orleans sits between the Gulf and a lake. It also sits in a bowl below sea level, so that enough rain, wind or storm can always flood it. Nothing can change that. Or can it? Why can't New Orleans do what they did in Galveston in 1900?

Between 6,000-12,000 people died in the great Galveston hurricane of 1900. By today's standards, it was a category 4 hurricane, with winds measured at 134 mph, before the wind guage blew away. It is still the worst natural disaster ever to hit the United States.

But Galveston counter-attacked. The city fathers decided not only to build a sea wall, but also to raise the ground level of Galveston Island, to get above future floods.

With primitive tools by today's standards, they jacked up the buildings, some 17 feet or more high above the ground. They even jacked up their stone cathedral! They put railings around the wooden sidewalks downtown, so people would not fall off as they shopped.

Then, while they conducted business as usual downtown, they dredged dirt out of Galveston Bay and out of a place on Galveston Island that is now a lake. With this dirt, they filled in layer after layer of dirt under their jacked-up buildings. Now Galveston sits permanently some 17 feet higher than before their terrible disaster, protected by a sea wall as well.

Why couldn't we do that in New Orleans? Raise the ground level?
There is no point in moving New Orleans elsewhere. A city is needed right there, to service the huge traffic in one of the busiest, most important ports in the world. The workers need a place to live in, reasonably close to the port.
But what point is there in continually rebuilding New Orleans, flood after flood? Or in being totally dependent on a huge, elaborate system of dikes and levees, which are subject to leaks, breaches and over-topping? Why not also correct the below-sea-level problem by simply raising the ground level ? We certainly have better tools now than Galveston did in 1900!
We could start in the lowest, worst parts of New Orleans. Buildings worth saving could be jacked up so that dirt could be filled in underneath. Those not worth the cost could simply be knocked down, covered over with dirt and buried where they are. (What a great treasure for future archeologists to dig up in a century or two!)
The higher parts of New Orleans could be preserved as is. The rest could be lifted out of its permanent danger zone. Instead of disasters waitiing to happen, buildings could be safe on ground raised to a higher level. Having a house or business in New Orleans would no longer be a toss-up between prosperity and bankruptcy.
If the old Galvestonians could do it, why can't New Orleans?
