Case Study: Tippecanoe County At the Tippecanoe County Extension Office, the community saw a
parking lot island as an opportunity for reducing runoff and
increasing green space in the area. This site allows for a 500 square
foot rain garden split into two gardens surrounding the path. With a
prime location for viewing and accessibility as well as the
effectiveness of capturing stormwater runoff, the installation of this
rain garden went underway following the steps of the Purdue
Rainscaping Education Program. This site allows for easy viewing
access to visitors and also an excellent example of the benefits of
Rainscaping.
Utilizing a landscape design and installation company, the area’s
soil was treated and shaped to prepare for the rain garden. Soil
amendments were added, and the land was formed to add a
depression to allow for water to drain into the garden. The
participants of the course planted native plants tolerant of a 24 hour flooding period as well as
other hardy and easy to maintain perennials such as blue false indigo, bottle brush grass, and
bottled gentian.
A year later, the rain garden is growing successfully and beautifully. It takes the runoff from the
Tippecanoe County Extension Office Building and surrounding parking lot and prevents those
pollutants from running off to near water sources making the rain garden an excellent example
of Rainscaping.
