Around noon on the day when Katrina hit New Orleans, Louisiana governor Kathleen Blanco told the Bush administration that the levees were safe:
"We keep getting reports in some places that maybe water is coming over the levees… We heard a report unconfirmed, I think, we have not breached the levee. I think we have not […]

From this:
Engineer Manual No. 1110-2-2502 is not a publication that would normally excite interest from the general population. But in the weeks and months ahead, as New Orleans struggles to rebuild from the floods of Hurricane Katrina, Section 4 of that Army Corps of Engineers book could be scrutinized intensely by city and state officials.

This page has pictures of the measures that various countries take to protect their coastlines from being flooded, ending with the New Orleans levee system. Point taken, but it's not exactly fair to blame the Army Corps of Engineers for fault that, once again, is shared by various levels of government as well as the […]

From this:
A difference in soil boring data transferred from one chart to another may have played a key role in engineering decisions that led to the breach on the 17th Street Canal floodwall that flooded much of New Orleans during Hurricane Katrina, National Science Foundation investigators say.
A cross-section drawing in the project design documents shows […]

The Army Corps of Engineers did a design review of the New Orleans levees in 1990. Apparently the engineers on the project thought the soil under the 17th Street Canal was stronger than it was, and one of their offices discovered this at that time:
Corps documents show the mistake of overly optimistic levee strength was […]

Army Corps of Engineers spokesman Susan Jackson responded to the news that Katrina was apparently weaker than originally reported as follows:
"In the Gulf, Katrina was a Category 5 storm, and the surge was still Category 5 when it hit the ground… It's the surge — the pressure of water against those levee walls — that's […]

The Army Corps of Engineers said the plan for improved levees that is being pushed by President George Bush is a good one for the areas where levees breached but will do nothing to protect the Lower Ninth Ward, New Orleans East or St. Bernard Parish.
…The plan calls for closing off the levees at the […]

Was the floodwall failure at the 17th Street Canal due to bad design by the Army Corps of Engineers, or bad construction by contractors?
They pulled eight sections of the steel sheets that were driven into the ground, and so far that seems to indicate that they were installed to the designated depth: "Engineers Reverse New […]
