New Orleans, fill it with dirt

Not as crazy as it sounds. Dig a big lake, convey the dirt over. All
the houses worth saving, raise them up on a new foundation. The
skycrapers, just make the bottom floor a basement. Expensive? Yes, but
a permanent solution. Better than it happening again.

It's been done befo

"After yet another massive flood in 1862, an ambitious project to
actually raise [Sacramento] above flood level was undertaken. Evidence
of the tens of thousands of cubic yards of earth and miles of masonry
work used to raise the streets can still be seen today in Old
Sacramento." And the downtown if you know where to look.

Galveston underwent a similar transformation after the 1900 storm.

Mexico City and whatever that lake was that they filled in - then built on..

At an altitude of 7,349 feet AMSL, the lake was considerably easier to
drain...

Yeah, the raised Galveston about 20 feet with fill as I recall. It's worked
pretty good.

Seem to me we should take all of that delta mud that keeps extending the
Mississippi and use it to fill in the parts of N.O. that can never be saved
and raise it to 20 feet above sea level. That would take care of a lot of
future settling. It would also shorten the Mississippi channel. The
historic and commercial sections of the city could be left in the "bowl" as
a major tourist attraction and would be mush less volume to protect and pump
out. A major major project but better than spending the money on some other
silly government project.

Silt doesn't make good structural fill because the particle size is too
small. Small particles don't well, and result in soil that moves once you
think you have it put in place.

Where is the runway in Asia they built on silt? The one where they designed
it to sink a foot or so in the first X years, then more or less stabilize?
Unfortunately, it is sinking faster than expected, and they will have to do
it all over again some day in the future.

So what is the problem?
You build it 50 feet higher.
