Bee Branch Creek (Iowa)
The years 1999, 2002, 2004, 2008, 2010, and 2011 saw very damaging floods totaling in costs to $70 million. The first storm prompted the city to research an engineering project on the 100-year floods. It was found that the sewers were not big enough for large storms. Detention basins, ponds that collect water, were added in the area. Also, the sewer became a river to hold more water.
