The City of Iowa City has completed several flood mitigation projects in response to higher than normal rainfall totals experienced in recent years.
Despite these projects, there are still some vulnerable areas around the City that may be impacted by an unseasonably wet season. River flooding and flash flooding are two different types of events that can occur in our area. Iowa River levels are impacted by the Coralville Dam outflows, as well as rainfall received north of the Iowa River basin, as well as local rainfall. Ralston Creek runs through Iowa City and unusually heavy or sustained rainfalls can cause flash flooding locally.
The purpose of this page is to supply residents with news, resources and guidance to assist during high risk events and seasons.
