Flood Control is budgeted separately from the staffed divisions, with the majority of the work being completed by members of the Streets Division as a part of their storm drainage system functions, and normally managed by the Street Superintendent. The flood control system includes underground storm drainage systems, drainage ditches, levees on both banks of the river and three pumping stations to eliminate surface water from retention ponds within the City during high river stages. Gates at openings in the levee may be closed during high water, and an emergency operations plan implemented. Routine maintenance responsibilities include mowing and maintenance of flood control levees, grounds around storm water retention ponds and large open areas such as Kanza Park, and inspection and repair of large pumping plant facilities. The project is inspected annually by the US Army Corps of Engineers.
