In 2008 it was Iowa City and Cedar Rapids. This year Ames is getting a turn. Oh, and throw in some serious flooding around Oskaloosa, Manchester, Colfax and elsewhere, not to mention the dam failure at Lake Delhi.
What’s going on? Why are towns, universities, farmers, the wealthy and the poor in Iowa all suffering from flood damage with frequencies far exceeding statistical expectations?
Point your finger at what you want: more development in flood plains and pavement everywhere, fewer functioning wetlands, degraded soil, more agricultural drainage tile, more row crops, and increasing frequency of heavy rains as a result of climate change. All play a role in causing havoc in Iowans’ lives and generating steep bills that have to be paid by someone, somehow.
What can be done? There are lots of things that need to be done, but a guiding principle that must be adhered to is a simple one: first, do no harm. We can’t continue to follow the practices and policies that have created the problems in the first place, or worse yet, create new policies or programs that create even greater flooding risk. Should we continue to build in flood plains? Should we continue to pave over agricultural land to build sprawling surface parking lots? Should we continue to follow agricultural cropping practices that degrade soil quality and reduce the natural ability of the soil to hold on to water? Should we “improve” field drainage so that water flows into rivers and streams even faster? The simple answer to all of these questions is no. Of course nothing, including finding policies that will address these issues while not causing harm elsewhere, is ever simple.
Stay tuned as IPP will be looking at some of these issues in encouraging policies that improve the management and quality of Iowa’s waters in ways that benefit all Iowans.
