We are not the DUTCH!


The Dutch lead the world in reclaiming land from the sea. There is no doubt they lead the world in engineering against flood damage. Since the 1953 event when the North Sea inundated significant portions of Dutch territory they efforts to give 10,000 protection have largely succeeded.

In this country most federal levees are calculated to protect against the so-called 500-year flood. Most private levees meet some other lesser standard.
A  federal district court has ruled in favor  of the USACOE blowing up a Missouri levee to protect Cairo, Illinois. Now on appeal.

Some suggest that not only the 33,000 miles of existing levees should be credited as protecting the property of those that would otherwise be occupying the 500 year flood plain or protected even somewhat by a levee for purposes of the NFIP. Administrator  FUGATE in a completely arbitrary and capricious decision has pretty much agreed to give all levees credit for NFIP maps even if they might never be built but are only authorized by some government.

From the wonkbook blog:

It is not just New Orleans that is unprepared for our present level of extreme weather, as WonkRoom explains in “Missouri Levee Failure Highlights Need For Increased Infrastructure Investments,” reposted below:

For several days, the midwest and southern U.S. have been pounded by deadly storms, which have brought tornadoes and widespread flooding. Today, a levee in Poplar Bluffs, Missouri, failed in at least four locations, which is “expected to send flood waters from the Black River racing into a populated but rural area of Butler County.” It is currently unclear how many people will be affected by the flooding, but the threat of the levee failing at another location prompted the evacuation of 1,000 people.

The levee’s failure is a tragic reminder of the sorry state of America’s infrastructure. This particular levee failed a federal inspection in 2008, receiving an “unacceptable” rating from the U.S. Army Corps. of Engineers. In the U.S. patchwork levee system, many local communities are responsible for levee upkeep, and this particular community couldn’t afford the cost.

According to the Army Corps of Engineers, nearly ten percent of the levees in the country are expected to fail during a flood event. The Civil Corps. of Engineers gave the U.S. levee system a D- grade in 2009, and estimated that it would take a $50 billion investment to get those levees into adequate shape:

“During the past 50 years there has been tremendous development on lands protected by levees. Coupled with the fact that many levees have not been well maintained, this burgeoning growth has put people and infrastructure at risk—the perceived safety provided by levees has inadvertently increased flood risks by attracting development to the floodplain. Continued population growth and economic development behind levees is considered by many to be the dominant factor in the national flood risk equation, outpacing the effects of increased chance of flood occurrence and the degradation of levee condition.”

Projected federal spending on levees in the next five years is expected to be just $1.13 billion, leaving a $48.87 billion shortfall in needed funding. According to the Federal Emergency Management Agency, “there are 881 counties — or 28 percent of all counties in the United States — that contain levees or other kinds of flood control and protection systems.” More than half of the U.S. population resides in those counties.

Overall, the U.S. has about $2.2 trillion in unaddressed infrastructure needs. The Congressional Progressive Caucus budget that was released earlier this month includes $30 billion “as start-up costs for a national infrastructure bank that would leverage private financing to help rebuild America’s public capital stock,” and budgets for $1.2 trillion in public investment over the next five years.

My view is that all levees will fail for one of three reasons: first the event exceeds the design frequency; Second, they fail to lack of being properly maintained; Third, they are blown up for aggravating floods down stream.

There you have it and not rocket science!

  1. From a friend:

    Perhaps even more significant, or at least a contender for your list of reasons why levees will fail, is that their control/maintenance/inspection systems are not coordinated, and thus in most regions any single levee failure will create a “single point catastrophic failure” of the regional “levee system.” I believe it is generally presumed that levees are under some larger management system based on hydrogeology, soil science, and flood plain management – the reality is, of course, that the levee system is so fragmented/fractured that as a system it is already failed – one just await the next demonstration of the management failure.
