[St. Bernard Parish], which unlike New Orleans lies above sea level, was protected by the levee from the Mississippi River-Gulf Outlet, a canal built by the corps that is now a subject of scrutiny. Completion of the canal four decades ago allowed saltwater intrusion that, the corps acknowledges, was a factor in the death of marshes that once helped protect the city from storm surges. Some experts say the canal may also have provided an express lane for the Aug. 29 surge to reach populated areas.
