At the urging of residents who have long felt forgotten in the shadow of more densely populated New Orleans, the Army Corps of Engineers says it will look into whether the city's fortified defenses pushed floodwaters into outlying areas.
However, the Corps has said it's unlikely scientific analysis will confirm that theory suggested not only by locals, but by some of the state's most powerful politicians.
Instead, weather experts say a unique set of circumstances about the storm -- not the floodwalls surrounding the New Orleans metro area -- had more to do with flooding neighborhoods that in recent years have never been under water because of storm surge.
The corps is expected to complete its study within two months. The agency said Corps researchers would conduct the study and that it will be peer-reviewed.
