June 2011 - September 2011
Matthew Placzek's Labor Monument
Became the Symbol of the 2011 Flood.
The 2011 Missouri River Flood was triggered by record snowfall in the Rocky Mountains of Montana and Wyoming and near record spring rainfall in the upper Missouri River Basin. High water levels threatened communities of all sizes along the river from Montana to northwestern Missouri, including Omaha. The flood forced the closing of several Missouri River traffic crossings in the flooded corridor and closed or damaged portions of Interstate 29.
The City of Omaha implemented a Unified Command Team that managed the community's response to the flood from May 30, 2011 to September 7, 2011. Team members included representatives from the Omaha Public Works Department, Omaha Fire Department, Omaha Police Department, Omaha Parks, Recreation & Public Property Department, the Omaha Airport Authority and the Office of Mayor Jim Suttle.
