This week’s segment looks at flood mitigation approaches that incorporate nature into city design.

Transcript:

As Iowa’s extreme rain events intensify over time, flood management considerations will need to expand beyond river floodplains.

This is the Iowa Environmental Focus.

Floods commonly occur when rivers swell over their banks, but flooding can happen far from river systems, too.  Urban flooding occurs when drainage systems fail to move large amounts of storm water away from developed areas quickly.

According to the Iowa Climate Statement 2018, scientists forecast that daily rainfall in Iowa’s most extreme rain events will double by midcentury, meaning cities and towns will have even more water to manage.

One solution is to replace areas of impermeable concrete and asphalt with green infrastructure. These swaths of soil and vegetation absorb and slow down water to process it more naturally and reduce flooding.

Green infrastructure can be incorporated into sidewalks, buildings, backyards and even parking lots. Rain gardens, bio-swales, green roofs and more bring plants, soil and mulch into community design in attractive and helpful ways.

This week’s segment discusses the recent flooding in Polk County.

Transcript:

Flooding in Polk County has impacted over five thousand homes this summer.

This is the Iowa Environmental Focus.

A June 30 torrential rain storm brought unprecedented volumes of rain as high as nine inches primarily to Des Moines and surrounding areas, leaving residents displaced and sixteen million dollars in damage to public infrastructure, homes, and businesses.

Des Moines has set aside over eleven million dollars to buy out eighty of the most devastated homes, and is offering interest free loans to its residents for repairs.

And it’s not just the monetary damage. The floods resulted in at least one death when flash-flood waters swept away a sixty-five-year-old man trying to get to safety.

As reported by The Des Moines Register, some of the flood damage to homes and businesses was due in part to insufficient storm sewer systems.

This week’s On The Radio segment discusses how a recent attempt to strengthen regulatory standards for livestock facilities in Iowa was shut down by the Iowa Environmental Protection Commission. 

Transcript: A petition to make it more difficult to build animal feeding operations in the state of Iowa was recently denied by the Iowa Environmental Protection Commission.

This is the Iowa Environmental Focus.

Under current law, applicants seeking to construct livestock facilities must meet only 50 percent of the state’s master matrix of rules and regulations pertaining to the structures. The petition, filed by two environmental groups, Iowa Citizens for Community Improvement and Food & Water Watch, requested that applicants meet at least 86 percent of the matrix’s requirements.

The Iowa Department of Natural Resources sided with the Iowa Environmental Protection Commission and recommended against passing the petition, both groups said that the proposed changes would be too stringent. Proponents of the petition pointed out that just two percent of applicants are denied permission to construct livestock feeding operations in the state of Iowa.

The current animal feeding operation master matrix was developed fifteen years ago by state lawmakers.

This week’s On The Radio segment discusses the Lake Michigan Ozone Study.

Transcript: Researchers at the University of Iowa are taking part in a collaborative field campaign to better understand the sources and transport of ozone near Lake Michigan.

This is the Environmental Focus.

The Lake Michigan Ozone Study is a joint effort of scientists at the University of Iowa, University of Wisconsin-Madison, and other research institutions to gain useful information about the concentration of ozone along all sides of the Lake Michigan shoreline.

Commissioned by the Wisconsin Department of Natural Resources and the Lake Michigan Air Directors Consortium, the study’s objectives include an evaluation of current regional ozone models and the effect of Lake Michigan’s breeze circulation on ozone transport.

Communities with little industrial activity on all sides of Lake Michigan have consistently experienced ozone levels higher than the EPA’s limit of 70 parts per billion.

Project organizers are still seeking additional  funding in order to install high tech, real-time monitors at various ground measurement sites in the region.

This week’s On The Radio segment discusses Sandra Steingraber and her recent visit to the University of Northern Iowa

Transcript: Long time environmental activist, Sandra Steingraber recently hosted a lecture, film showing and discussion at the the University of Northern Iowa.

This is the Iowa Environmental Focus.

Steingraber visited UNI to discuss three of her recent articles and give a lecture entitled “Be Arrested If Necessary.” She spoke about the role of environmental science as a catalyst for political and cultural change.

Sandra Steingraber, lives in Trumansburg, New York and has worked for years with government officials and other activists to bring about changes in her home state and around the country. She is a co-founder of Concerned Health Professionals of New York and New Yorkers Against Fracking and is currently the science advisor to Americans Against Fracking. In twenty-fourteen she led a successful campaign against fracking, resulting in the process being banned in the Empire State.

Steingraber is working hard to bring awareness to the effects of environmental degradation due to chemical contamination, fracking, shale gas extraction and climate change.
