The EPA and the Bayou.
We would all be long dead before you ever got permits.
You also are talking about an island, not a shoreline.
Water can come towards NOLA from any direction.
When they had the opportunity (large areas with houses more than 50%
damaged), it would have been a lot cheaper to just fill the bowl.
I am not even sure how FEMA allowed anyone to rebuild below the datum
plane. You sure can't do that in Florida. 50% damage based on the tax
assessment of the building, not including the land, you tear it down,
fill above the datum plan and build or build back on pilings.
The remedy to the 1953 floods was the socalled Deltaplan. Because, like
NOLA, the most affected part of Holland is the delta of the Rhine, Meuse
and Scheldt rivers. Much of Holland's economy depends on activities
below sea level. The defense is to keep improving (and often increasing
the height) of dikes, and generating ways to divert water. Same types of
things could be done around the world, especially NOLA.
The 1953 storm in Holland was very similar to Sandy - extra-ordinary high
tides, and a big storm that pushed up the sea against the funnel formed
by the land: In 1953 the funnel was the North Sea between the southern
parts of the English and Dutch coasts, leading to the English Channel.
With 2012 Sandy, it was the funnel of the coasts of NJ and Long Island.
Building codes were changed in Holland (no more homes built into the
dikes as was customary in some places) and a very much shortened primary
defense was built to replace the hundreds of miles of dikes around
smallish islands. That isn't quite possible in NY/NJ, but is done to
some extent around Lake Pontchartrain.
Around Rotterdam waterways were protected with movable locks/dams, as was
done as well near London. Something like that ought to be done in New
York to protect the infrastructure around Staten Island, in Manhattan and
up the Hudson, etc. But it won't be done, because it is cheaper to react
to disasters than to prevent them, certainly in the short run.
You clearly don't understand the dynamics of NOLA, The COE or the local
Done right the area can be secure. Bean counters chose not to do what was
necessary and bet on the come (aka a sucker bet). LSU predicted years
before exactly what played out during Katrina. COE/government big wigs
walked out of that conference.
The same computer model (with appropriate adjustments for local conditions)
was used on NYC area and the result predicted exactly what transpired with
BTW I grew up in NOLA (my family has been there since almost the time of the
French settled the area) and ran the river, the waterways and the marshes
since I was old enough to swim.
FWIW less than 10% of NOLA is above the datum plane if by that you are
referring to sea level.
That is not a simple as you would want others to believe. (And no I don't
plan to go into the engineering)
Regardless there are other alternatives that are both cheaper and more
appropriate/effective responce to the problem.
Good idea but move to where?
The key to why NOLA is were it is is the Mississippi River. A fact that has
been known for several hundred years.
NOLA is the most inland port available on the Gulf Coast. Seagoing ships
can make it to NOLA with a lot of work on the part of the COE. Much further
north and that access is only part of the year (Like RIGHT NOW) often with
partial loads. (Like RIGHT NOW)
No boat drawing more then 10 ft of water can go beyond Baton Rough.

The river is also too low for barge traffic up north.
If the barges can't get down river, what will they be shipping?
If you have to truck the products, truck them to Galveston.
Low water (and high water) happens every year on the Mississippi to various
degrees, been that way for eons. Typically not a problem as the system
adjust the barge loads to deal with the eventuality. An aside high water
has been known to causes more problems than low water but that's a subject
for another discussion.
The point I made and you seem to want to ignore is that deep draft ocean
going commerce carriers can't get up river beyond Baton Rough. It's not a
political thing, it;s not an economic thing it's a physical fact of nature.
So the idea of moving the city is not practical either physically or

Even though the Mississippi has a limited draft inland water, barges are
much much cheaper to move bulk cargo than any other transport available.
(for some product pipelines are a very close second) That's not rocket
science but pure hard economic fact.

There is no need for all that. What you do need is good sea defenses.
Rotterdam is the biggest port (at least according to some measures) and
it is largely below sea level. Centrally located for river barge traffic
up into Germany and even Basel Switzerland. A new freight railroad was
built from Rotterdam to the German Ruhr industrial area. Through an area
called Betuwe. Almost totally below the levels of the rivers surrounding
the area for 75 to 100 miles east. So this can be done. Costs a lot of
You have no idea how much raising the entire area to an elevation that would
protect the city would cost do you? Hint: the bean counters had a heart
attack when folk wanted the levees, along, built up to that level.
Yes I do but they have raised vast areas in Florida above flood level
with dump trucks. NOLA has the advantage of the river and barges.
Trust me,m it is chump change compared to what Katrina cost and what
the next one will cost. That assumes lives are free.
Hurricane Sandy will be returning this January. It's estimated to
return on or near Sunday January 13, 2013. It has developed at least
five times the power it had the last time it passed through, so there
will be much more damage this time. It will affect all 50 states and
other parts of the world.
