Urban Iowa: "Once you put asphalt over the top of it, there's no reclaiming it"
Today we continue our summer series on the environment by taking a look at urban development – what we’re doing right and wrong.
“Iowa is basically doing what the East and West coast did 20 years ago; but we haven’t learned from them," says Ankeny resident, LaVonne Griffieon.
When we think of urban sprawl, cities like Chicago come to mind, with several hundred towns surrounding the city. But Iowa is not immune to the concept of urban sprawl – and the state has its own debates about urban development.
Take Ankeny, for example, just outside of Des Moines. Ankeny's population has more than tripled since 1980, making it one of Iowa's fastest growing communities. LaVonne Griffieon is an Ankeny resident who runs a century farm with her husband. She predicts that one day Iowans will regret being too quick to develop on potential farm land.
"We may have wished that we had preserved some of the soil, instead of putting housing on it," she says. "Once you strip it away and put asphalt over the top of it, there's no reclaiming it."
This hour, we look at what is happening in Iowa when it comes to urban land usage: the environmental challenges urban sprawl brings, what communities are doing to redevelop their cities and to develop sustainable "green" planning, and how feasible it is to develop sustainable infrastructure and public policy.
Here's a unique Iowa project featured on the show - Dubuque's "Green Alley" program.
The Green Alley project came about to reduce flooding. Dubuque has about 1300 homes that regularly flood, and that’s with a flood wall. Permeable pavement helps water soak through the street into the soil, while improving water quality by acting as a filter to keep sediment and pollution out of the river.
More information on the project can be found here. 13 to 14 alleys currently have the permeable pavement, and in 20 years, they hope to have 250 alleys reconstructed.
