You and fellow students from Jerry Schnoor's Sustainable Systems course built the UI Press rain garden, the first rain garden on campus. And you also built a berm that has kept water out of our basement. Tell us how you did this.
As part of the UI Press rain garden design, we had to remove some existing soil to make sure the rain garden was able to correctly collect and infiltrate water. We thought it would be a good idea to try to use the excess soil to prevent water from entering the basement. Amy Bouska, an urban conservationist with the Iowa Department of Agriculture and Land Stewardship, recommended that we construct a berm that would divert rainwater runoff into the grass instead of letting it run along the side of the building where it eventually found its way into the basement. This turned out to be a simple and efficient solution that allowed us to use our existing resources to solve a water management issue.
You’re studying environmental engineering and science. The old-fashioned image of engineers—men in hard-hats standing around large construction sites with clipboards in hand, imposing order upon the natural world—seems to have vanished. How are today’s engineers integrating the natural and the built environments?
The field of engineering has certainly evolved over the years. As an environmental engineer, my job is to utilize science and engineering principles to develop solutions to environmental problems. A great example of integrating the natural and built environments is low impact development or LID. The purpose of LID is to work with nature to manage stormwater runoff by employing techniques such as preserving and recreating natural landscape features and decreasing impervious areas to create appealing and functional site drainage that treats stormwater as a resource rather than a waste product. Rain gardens, bioretention facilities, green roofs, rain barrels, and permeable pavements all help reduce the impact of built areas and promote the natural movement of water within an ecosystem.
