flood wall failed at River Drive and Pershing Avenue sending the Misissippi River into several blocks of the community on April 30.

The temporary floodwall made of HESCO barriers that failed Tuesday in downtown Davenport would have held for a predicted flood level of 20.5 feet,but when the forecast was adjusted upwards on Monday, there wasn't time to build fortifications, Nicole Gleason, Davenport's public works director, said.
