Rebuilding New Orleans With Science 564
EccentricAnomaly writes "The New York Times has a discussion of flood control methods in use in Holland, England, and Bangladesh that could be used in the rebuilding of New Orleans. Of particular interest is the $8 billion Delta Works built by the Netherlands in response to the North Sea flood of 1953, which almost destroyed the city of Rotterdam, but for a heroic captain who plugged a breach in a dike with his ship." From the article: "While scientists hail the power of technology to thwart destructive forces, they note that flood control is a job for nature at least as much as for engineers. Long before anyone built levees and floodgates, barrier islands were serving to block dangerous storm surges. Of course, those islands often fall victim to coastal development."

On March 1, 2003, the Federal Emergency Management Agency (FEMA) became part of the U.S. Department of Homeland Security (DHS). FEMA's continuing mission within the new department is to lead the effort to prepare the nation for all hazards and effectively manage federal response and recovery efforts following any national incident. FEMA also initiates proactive mitigation activities, trains first responders, and manages the National Flood Insurance Program and the U.S. Fire Administration.
Certainly the local and state governments deserve a huge amount of blame for not having concrete evacuation procedures ready for the poor, but the federal response - FEMA's only serious duty - was outright embarrassing. And I know you don't want to fault the administration, but their vacation schedule while people were dying was outright embarrassing - Bush, flying over *two days* after New Orleans flooded, was among the first, with Cheney still vacationing in Wyoming, Andrew Card vacationing in Maine, and Condi spending the day shoe shopping at Ferragamo's and watching Spamalot.

As the city drowned and went to anarchy, no active duty military were sent in, and only a handful of poorly equipped national guard (the 256th's support brigade having most of their disaster recovery eq).

Enough money was never made available for reconstruction of the wetlands or barrier islands, or for improving the levee system.
Three times during the Bush administration funding has been slashed to 1/6th to 1/10th of needed levels to properly address the above issues. The loss of live may climb to ten thousand or more, with property damage in New Orleans proper that could reach $15 Billion USD. It would not be the first time that the neo-conservatives have been exposed to accusations of being "penny wise and pound foolish".

New Orleans is placed on a river delta. After the sediments in a delta are deposited they are guaranteed to subside. It's a consiquence of compaction, de-watering and the isostatic response of the lithosphere below the basin to the extra load. Unless more sediment is added continuously the delta will eventually (and quite quickly in geological and indeed historical terms) sink beneath the sea.
When New Orleans was founded a few hundred years ago it was above sea level. (after all, who would found a town on a salt marsh?) Since then it's subsided continuously until today a great deal of the city is now below sea level and a great deal lower than the river (which has since built up its base by depositing sediment).
When the corps of engineers stopped the river naturally switching its channel (which it does around once every 1000 years) and straightened the current channel they put in motion a set of events which meant that the delta lost its sediment load to further out in the Gulf of Mexico as the river is flowing at a greater rate. This has caused the coastline (and all the natural defences) to not be replenished and go below the sea.
You may like to see this google cached article [64.233.183.104] from a Baton Rouge newspaper in 2002. It gives a decent overview of the situation.
As a geologist, I would be in the camp which suggests that the government take this as an opportunity to move the city to higher and more stable ground and abandon the old city to be an archaeological curiosity and tourist attraction. Rebuilding it would merely prime the charge for an even bigger loss of life when, not if, the river breaks its banks. This time only the low-level lake to the north broke through which soon equalised its level.. this wouldn't happen with the great river.
How long do you want to fight a losing battle with the planet? How high do you eventually want the levees to be before you give up? When the city's subsided to the point where it's an isolated bowl in the ocean?

Blame is being passed around, something that politicians excel at. However, the Feds are not the only ones at fault. One must consider the city's priorities when they built a sports arena and did not work on their levees. One must also consider the refusal of the citizens to pay higher taxes to do both. The federal government cut funding, but if the city had REALLY wanted to fix their levees before Katrina, they could have made some hard choices. Instead, they chose to court the Charlotte Hornets and get them to move to the Big Easy. Just as a "for example."
Now, a massive rebuilding effort needs to take place, and one after the rescue and mitigation efforts are completed. The rebuilding will probably outpace the fortification of the levees, as people will want to rebuild their homes and that doing that on an indiovidual basis is smaller and easier than re-engineering levees.
However, before they do that they should consider that their new homes are in as much danger as the ones that they lost until they get their flood control issues resolved. This should be priority one for the city, the state of Louisiana and to a large degree the federal government. The cost will be in the billions, and I for one will be very surprised if the money is easily available.

We should expand City Park to encompass the entire Bayou area, with no development, and lots of canals. Expand the Bayou itself in the bottom to become a giant reservoir. When storms approach, pump out the reservoir. Make all drains pass through the reservoir, a giant buffer. When rain and failed seawalls allow water into the city, funnel it into the reservoir, buying time. Pump the reservoir into the Mississippi and the Lake.
The seawalls and levees themselves are not fault-tolerant. They're static, brittle, and take the whole city with them when they break. Those walls should all have rail lines along their inhabited sides, separated from the water by the wall. When a storm approaches, dumpable sandbags can be rolled into place behind risky sections, or into broken sections, or just into staging areas for delivery by helicopter, boat or amphibious vehicle, or even human "bucket brigades" when all other vehicles fail. Ahead of the storm, the rails can carry cars of evacuees out. And the other 99.5% of the time, without emergencies, they can carry cars instead of highways (most cars on I-10 are "just passing through"), passengers and freight.

I think that reclaiming the old Back of Town from the Lake was executed in an unsustainable way. I think you misunderstand what I'm talking about: Bayou St. John isn't the source of the water flooding the neighborhoods. It's where the water goes. Rather than pretend we can fight the vast power of nature head-on, we must learn from our mistakes to do what we actually can, to get what we want. Like allow the water to enter the city when we can't prevent it, and spend our energy on making those floods controlled and manageable.
New Orleans once was already compartmentalized with neighborhood levees, as you suggest, in the wake of an earlier flood. When the next flood came through, people broke holes in the levees keeping the water in their neighborhoods (which was keeping downhill neighborhoods dry). So the next neighborhood flooded, and those levees were broken, and so on. These strategies that merely meet the force of Nature with force of engineering show how powerful ins Nature: a 90MPH/40mi-wide hurricane contains 200x the global electrical generation power; Katrina was many times bigger.
So I suggest we plan for "failover". That means sacrificing some land areas in populated New Orleans while it's manageable, rather than all of it when the crisis hits. Many of those areas we can't keep are really desireable property now: quiet, modern neighborhoods near the Park. And of course it's easy for me to say, since I already said my tearful goodbyes to the city when I moved back to NYC. But whose neighborhood should go? Just the poor people, even if their neighborhood isn't as useful a sacrifice in the engineering to protect the city?
I know what it means to miss New Orleans. I've cried often this past week, screamed at the set, sent money, helped find people, helped find people places to stay. I didn't think I could be more furious with Bush and Congress than the past 5 years, but this storm surprised even me - in revealing just how through was their failure. I've got other wheels in motion here in NYC that hopefully will have immediate and longterm benefits to saving the city - in my own relatively puny way. I hope every one of us is also doing what we can - together we can save the coolest, most unique city in America. But we have to accept that we might have to amputate to save this patient. No one's going to like it. Until I hear about a better operation, that's at least as likely to preserve her life, I'm sticking with this one, painful as it is.

Rebuild? There's a Bright Idea. (Score:5, Insightful)
The Netherlands argument just doesn't hold water (no pun intended) because that part of the world isn't subject to the same type of weather conditions - in other words, there ain't no hurricanes in the North Sea. There are also the economic factors to consider. The United States is in debt over its head and frankly doesn't have the financial resources to waste on rebuilding a city which would then require greater and greater expenditures of capital to keep from being inundated as the ocean level rises.
Rebuilding New Orleans shows stubbornness well beyond the border of idiocy and is a stunning example of the old axiom: "an ounce of prevention is worth a pound of cure." It also shows the tremendous amount of greed involved; whether or not New Orleans is rebuilt, the impoverished who have borne the brunt of this disaster will be left out of the process, except maybe as a disposable work force to exploit in the building of new condos and upscale developments that the real estate markets in New Orleans have been looking for an excuse to install -- especially since builders can use such low-wage exploitation as a tax write-off.
Then there's also the fact that developers were allowed to build in hazardous locations to begin with -- what with the Bush Administration doing away with the Federal land easements (wetlands) that existed as a storm surge buffer and turning it over to developers.
Sacramento, California is an example of just such short-sightedness. The Sacramento River flood plains are catastrophically inundated every ten to fifteen years or so. Despite this fact, developers have been allowed to build there because they've bought and/or sued the city & county into letting them do whatever in the hell they want. The developers have also stifled the environmental and news reports as well as done their best to obscure the historical record because such information conflicts with their immediate profit interests. The result? Houses get flooded, families are ruined and the taxpayers are left with the responsibility.
Frankly, developers don't give a shit whether five or ten years down the line those houses are flooded out and destroyed, incidentally sending into financial ruin the families gullible, desperate, uninformed and/or stupid enough to be living there. They've made their profits and get to hide comfortably behind the lawsuit protection laws established to prevent consumers from holding developers responsible for faulty and/or dangerous housing. Besides, the government will pay for disaster relief and subsidize the rebuilding efforts for a new generation of suckers -- because once those houses have been built, by God they've got to stay there.
With the the Bush Administration doing the best it can to aid unscrupulous businesspeople by circumventing legal measures set up to prevent people from putting themselves into harm's way, is it any wonder there's such a cry to rebuild New Orleans? You've got people who stand to make a killing by exploiting this very preventable disaster. But then again, I guess caveat emptor is the ultimate answer and anything else is heresy to the religion of the Free Market.
Let this also serve as a reminder those who believe overpopulation is a myth that not every square mile of the Earth's surface is inhabitable or arable.

The answer to "how" might seem more novel - and less expensive - than most people think. Simply accept that the area is going to flood. Now build the city such that water and flooding becomes an integral part of the urban planning. Canals and locks can move heavy goods more efficiently than trucks. Build physical plants on elevated earthen damns, and just accept that streets and parking lots are going to flood out. Ban residential construction in flood-prone areas (should be a no brainer). Convert existing structures such that the first two floors above ground (or within the 20ft flood stage) are used for parking and industrial plant works. Lastly, use locks on the channels so that when (not if) a levy breaks, that section is automatically sealed off.
Engineering a city isn't impossible. It's hardly difficult. It merely takes the will to do it.
Adapt! (Score:3, Interesting)
New Orleans as it is should be adandoned. The high ground of the french quarter might be preserved. The deep water port and industrial areas like Michoud are restored. These areas have proper seawalls built with regard to natural silt flows, the rest of the city becomes Delta again. People that live in the area live the way you're supposed to in a swamp: in boats and house-barges. The swamp dwellers seem to have faired well, and came out of the woods to help evacuate the city. If the population was competent enough to live in the swamp instead of against it, they could flourish. As it is, they have probably crippled the shrimping and subsidence issues doom much of the city. Imagine a million houseboats stretching through a restored river system. People commute to work by boat, work in hi-tech, shipping and restored shrimp industries. Let the Mississippi wander as it needs, build the deep-water port out in the ocean and have lighter barges for carrying containers and oil in-shore. If people want to live there, they should adapt to life on the water.
