Innovative Stormwater Treatment Practices Introduced to Ohio

With more frequent heavy storms, traditional “pipe and pond” approaches to treating stormwater fail to adequately prevent flooding and protect water quality.

The Old Woman Creek National Estuarine Research Reserve worked with the Chagrin River Watershed Partners to demonstrate, assess, and promote nature-based stormwater management alternatives that use rainwater infiltration techniques, including three bioretention cells (landscaped depressions that capture and treat stormwater runoff), four permeable pavement applications, and a permeable pavement and cistern combination. (The bioretention and permeable pavement test sites, for instance, provided runoff reductions of up to 50 percent.)

Test results are being used to improve stormwater management techniques throughout the state. Team members have participated in a number of training events for stormwater professionals, and are helping officials incorporate these findings into local codes and the state’s Rainwater and Land Development manual.
