Why can't New Orleans do what Galveston did 100 years ago?

I keep thinking, Why can't New Orleans do what Galveston did 100 years ago?
If anyone knows the answer to this please let me know.

Many people may have heard about the hurricane of 1900 that hit Galveston. Few know the entire story.
When visiting down there you can see films of the devastation. I have gone to their library archives and carefully thumbed through the photos. I have also read a journal of a little girl who survived it.

What is most fascinating is that Galveston raised the entire Island. Why can’t New Orleans do this?

Here are some facts
• 1900 storm killed 8,000-12,000 people
• They had no way of getting rid of the bodies so they brought them out to sea, but not far enough they washed back in with the tide
• 120 mph winds category 4 storm
• Galveston was raised 17’ above low tide, built a sea wall 3 miles long

Here are some links to the history of Galveston, the hurricane of 1900 and the raising of the island.
