NEW ORLEANS (AP) - In response to concerns, the Army Corps of Engineers says it will monitor possible sinking over time of 23 miles of levee and floodwall protection it built after Hurricane Katrina to protect St. Bernard Parish, an area that suffered catastrophic flooding in the 2005 storm.

In a report released Monday, the Army Corps says the weak soil beneath the levees and concrete floodwalls it built around St. Bernard could cause the 75-foot-long pilings to bend over time. But the agency stressed that there was no immediate concern and that there might not be any problems in the future.

The corps spent about $1 billion to build a much higher and stronger flood protection system around St. Bernard after Katrina.
