CORRECTION: The original title was wrong, as pointed out by mominem in comments. It said: "We Will Not Be Protected from a Hurricane 25% as Strong as Katrina until 2011." A 100-year storm is four times more likley to come in any year (if my math is correct here) than a 400-year storm. But, not necessarily 25% as strong. I hate being wrong. The following info is still worthwhile, however.
Dozens of construction projects launched by the Army Corps of Engineers to protect the New Orleans region from the most catastrophic floods are behind schedule by an average of nearly eight months, an internal audit shows. Local officials are concerned the completion date will have to be pushed back a second time.Katrina was a 400-year storm. The US Army Corps of Engineers is building a levee system capable of handling a 100-year storm.
Local officials worry that the corps now will miss its revised June 2011 deadline for getting the region protected against a 100-year flood — a flood so bad it has only a 1% chance of hitting in any year. The corps pushed back its original January 2010 deadline earlier this year.
I just thought I would point that out to the rest of country.
