In the wake of recent stormy weather, Iowans are remembering the various floods that the state has survived over the past few decades. Thunderstorms, tornado warnings, and flash flooding are all par for the course during late summer, but the flash flooding especially can have some nasty effects on the infrastructure of a city.

When a city begins to flood, its sewer system is affected first, overflowing with the excess water and pouring down the streets.

While pooling floodwater damages the foundations of houses by slowly weakening the foundation materials, it is actually the initial impact of the floodwater that causes the most damage, shifting buildings over slightly in some severe cases.

Areas suffering flood damage also significantly decrease in market value, making it difficult for the affected families to afford repairs or resell their property down the line.

As Iowa City and Coralville prepare for flood season, it’s important to remember just how damaging floods can be for an unprepared city.
