It’s already doing that. However most of New Orleans is below sea level and that entire part of the state is a river delta/swamp. All of that low lying swampland is receding, potentially leaving New Orleans as a small island out at sea.
You can no longer just protect the city from floods, no longer just reinforce the coastline, you’d have to protect the entire lower part of the state. And it’s not just rising sea level, but floods from the entire Mississippi watershed, and hurricanes. That’s just not reasonable or sustainable
That might work if the streets are raised 1 story and the streets become the tidal barrier. This is how the seattle waterfrony was built in some areas.
Imo though I think it makes sense in the long term to just consider the entire area a tidal or submerged area and build/modify accordingly on stilts/pilings and then backfill around just the stilts/pilings.
Roads are too flat and won’t be navigable when partly submerged. Imo thats why it makes sense to build out canals that can be navigated at low tide. The sidewalks can then serve quadruple duty as sidewalk, utility areas, mud barrier, and dock.
Can’t New Orleans do what the Netherlands did?

Netherlands doesn’t get nearly as many hurricanes.
New Orleans is probably looking more at a Venice situation. Pull out the roads and carve out canals
The Netherlands also built the sea wall at Venice.
We do not get hurricanes, but we did build a world wonder to ensure Zeeland doesn’t get flooded again. Source
Japan is able to build defenses against a tsunami. There are options.
Just move up to the 1st floor. The roads will turn into canals of their own accord.
