It is estimated it will take two more years to finish.
"For heavily-populated urban areas, where the failure of protective structures would be catastrophic -- such as New Orleans -- this standard is inadequate," the report said.
This independent group urges that the city should have either 500-year or possibly even 1,000-year levees and floodwalls. They insist that the same kind of engineering standards utilized in earthquake zones should be used in New Orleans.
And there is more. Because of this future vulnerability to flooding, the panel asks that the city consider not allowing the population to reside in those areas vulnerable to the flooding. They especially target those areas of New Orleans that are below sea-level which is about 49%
of the city. The point made by the report is that New Orleans is a unique situation, and living there means some risk. Good decisions about where to rebuild should be made.
However -- and here's the future -- Mayor Ray Nagin and others of the local government have stated that the government should not dictate where people can live. As a result, the city, according to Maggie Merrill, Nagin's director of policy, meets with the Army Corps of Engineers regularly, and the city itself is "trying to rebuild its facilities higher and stronger."
This is not good news since the Army Corps of Engineers estimates that the 350 miles of levees and breastworks protecting the city might take, according to their estimates, 20-25 years to complete to upgrade to Category Four or Five storm status.
Martin McCann, a civil and environmental engineering professor at Stanford University in California, warns that even that long-term planning may not account for changes to the risk equation. "As further development goes on behind levees, over decades you need to revisit the question and say, are those levees providing us the protection that we wanted?" he said. "The answer is probably no, because the exposure is probably greater. The number of people and the [amount of] valuable property [behind the levees] is greater."
Many of the same coastal scientists and engineers who sounded alarms about the vulnerability of New Orleans long before Katrina are warning that the Army Corps is poised to repeat its mistakes -- and extend them along the entire Louisiana coast. If you liked Katrina, they say, you'll love what's coming next.
There are quite a number of geologists, geographers, and engineers who agree with the assessment that New Orleans cannot just be rebuilt on "old" ground. They recommend a number of measures such as relocating part of the city to higher ground, limiting where people can rebuild their homes, moving the outer-edge "sprawl" that exists so that the cypress swamp can regenerate itself as a buffer zone for the city, or increasing taxes of some sort to pay for the natural disaster that is sure to follow.
Other Portents of an Ill Future
(Bergal, et al., 2007) in their acclaimed book, A City Adrift: New Orleans Before and After Katrina, confirm that in 2004 the city of New Orleans had a long-delayed, massive hurricane preparedness exercise funded by FEMA. The scenario turned out to be incredibly similar to the aftermath of Hurricane Katrina with widespread flooding and hundreds of thousands of people displaced. Many of the same breakdowns in communications, evacuation, and health care that would later occur during Katrina happened during the exercise.
"The real storm rendered the communications system -- local, state, and federal -- practically inoperable. The buses that were supposed to evacuate thousands of people never came. Most hospitals lost power and had made no arrangements to evacuate patients. The nations' disaster medical system, which deploys teams to assist in such emergencies, was stopped up [not by technical problems,] but by bureaucratic problems that stymied its effectiveness.
The social services network that was to have been there to pick up the pieces was nonexistent in many areas."
After all the previous warnings about what a storm could do to the city, and after a massive test of its capabilities only a few months before and lessons learned from that exercise, the whole system -- almost everything -- crumbled when Hurricane Katrina rolled into town. The why of all of that is left for another time.
But the importance here is that we are looking to the future, and the "corrections" New Orleans, the state of Louisiana, and the federal government are supposedly making to all...
In the meantime, a number of interim technologies are widely available that are paving the way towards ubiquitous computing, including Wi-Fi technologies that provide wireless communications services to large numbers of users within a metropolitan area. Conclusion In sum, the research showed that the city leaders in New Orleans struck while the legal iron was hot by formulating plans to deploy a citywide Wi-Fi network that exceeded the limits allowed by
Folkman, MI. California Engineer Sees Fears About New Orleans Levee system Come True, 2005 The author writes about the thoughts and experiences of Robert Bea, civil engineer at the University of California in Berkeley on the recent killer hurricane in New Orleans. Bea studied the city's levee system since 1954 when began working for the U.S. Army Corps of Engineers, He discovered that it was not high enough and that parts
New Orleans Flood Control System Analysis Dr. Maribel Mojica Howell This paper will look into the cost and benefit analysis of the New Orleans Flood Control System. The origin of the flood protection system and its mode of operation will also be discussed. Finally, we will evaluate the expenses of running the system as well as the valuation of expected returns in case of a subsequent calamity. The engineers faced with the task
New Orleans Should Not Be Rebuilt Throughout history, humans have learned the hard way that living in some parts of the world is risky because of any number of factors, such as living near an active volcano such as Pompeii or earthquake- or flood-prone regions such as along the Yangtze where millions of lives have been lost over the centuries. In some cases, the geographic attributes of such regions are
This is one way in which the city may find a compromise with its perceived problem of the influx of Hispanics. The Central Business District is growing and finding the tourist trade to be coming back, but it is only with the help of the Hispanic population that it will continue to grow. In the Central Business District, public and private buildings are still being rebuilt. The delay in making
