Johnson County Soil and Water Conservation District

Bioretention Research Grant 

In the summer of 2014, JCSWCD was notified that it was awarded a grant to conduct research on bioretention practices in the State of Iowa.  The focus of this project is to gather information on the water quality benefits and costs of four different bioretention practices in Iowa.  Staff and partners will research bioswales, bioretention cells, rain gardens, and enhanced rain gardens.  The project will compare water quality protection of practices and contrast cost of traditional stormwater management practices versus new approaches.   

 

Bioretention is one of the main practices for infiltrating stormwater.  Bioswales, bioretenion cells, enhanced rain gardens, and rain gardens all look similar on surface.  However, they each have their own distinct design specifications.  This project will gather information on each of these bioretention practices and compare their performance and their costs.
