In late fall 2011, Culver's Landscaping constructed the first rain garden on
Coe College's campus. The rain garden, which is located north of Hickok
Hall, is designed to divert runoff from Hickok's roof from the storm sewer and
instead let it infiltrate to groundwater. In addition, the site will be
instrumented to allow Coe students and faculty to collect data on the flow of
water into the rain garden, the water level within it, and the movement of soil
moisture through the profile. The rain garden will serve as a model for
others interested in installing such a feature and will provide data for student
and faculty researchers.

The creation and instrumentation of the garden was funded by the
senior gift of the Coe class of 2008 and a Community Partnership
grant from the Cedar Rapids
Linn County Solid Waste Agency. In-kind support also
came from Culver's
Landscape, Amy Bouska (Iowa
Department of Agriculture and Land Stewardship), Jon Gallagher (Linn
County Soil and Water Conservation District), and Dr. Mary Skopec
(Iowa Geological Survey
Bureau-Iowa Department of Natural Resources).
- Keith Schilling, research geologist from the Iowa Department
of Natural Resources, gave a presentation at Coe on February 23,
2012, titled "Do we have increased flooding potential in Iowa's
river systems"? You can view his slides
- Marty St. Clair gave a presentation on the Coe rain garden to
AGN300, Rain Gardens and Bioretention Cells, at Kirkwood Community
College on October 25, 2012. The course is taught by Wayne
Peterson, coordinator of IDALS Urban Conservation program.

- Instruments have all been installed, and they indicate that
the rain garden can easily handle a fairly hard one inch rain with
no surface ponding.
