New Orleans flood-control system not as advertised
The maps showed that the improvements made to the city canals' drainage systems would reduce flooding during a major storm by about 5.5 feet...But in a report released November 7, Corps scientists estimated that the actual benefit the system would provide would be just 6 inches.
...mistakes were apparently made in the calculations for two sub-basins that include Lakeview and nearby neighborhoods. In one, a minus sign was used instead of a plus sign..
whoopsie!
