Comments to the Iowa Department of Natural Resources are still needed in support of a 2012 rule that requires developers and home builders to leave four inches of topsoil on the ground after construction. Bleeding Heartland discussed this issue last week, and Todd Dorman wrote a more detailed background piece for the Cedar Rapids Gazette earlier this month. I’ve posted excerpts from that article below.
Iowa has lost too much of its world-class topsoil already. Not only does this non-renewable resource help plants grow, it reduces stormwater runoff that can cause flooding and water pollution. As Dorman points out, homeowners would also benefit from having more topsoil on their lots, so they could grow grass or other plants without having to inundate hard clay subsoil with chemicals. Representatives of business groups that oppose the DNR rule have estimated its cost at between $1,200 per residential to $2,500 or even $5,000. I haven’t seen any estimate of the hidden costs of more flooding and excess nutrients in waterways. Although farms contribute more to Iowa topsoil runoff than new residential construction does, we all have to do our part.
A public hearing on the soil conservation rule is happening this Thursday, May 29, in Des Moines; click through for details on how to participate in person or by phone. Public comments can be sent via e-mail to Adam.Schnieders AT dnr.iowa.gov, ideally before Thursday’s meeting.
