Best Management Practices

Best management practices (BMPs) are the actions homeowners can do to reduce the quantity of stormwater runoff leaving their property. For more detailed information about the following BMPs— including potential cost-share opportunities here in Tippecanoe County—click on the BMP title or visit www.TippEcoNow.com

Rain Barrels

Rain barrels capture stormwater runoff from rooftops via downspouts. The water in the barrel can then be used for water gardens, lawns, or can simply be drained once the ground is no longer saturated from rain. 

The Wabash River Enhancement Corporation (WREC) offers a rain barrel kit (barrel, stand, and downspout diverter) to residents within their target watershed for just $25. Contact WREC to find out if your address qualifies for a reduced-price rain barrel kit. 

This video from Purdue University Extension shows the full rain barrel installation process. 

Rain Gardens

Rain gardens are shallow depressions in a property, intentionally designed to accept drainage. Rain gardens are planted with native flowers, shrubs, and even trees that are moisture-tolerant and help infiltrate the excess water. 

Example rain gardens in Tippecanoe County include roadside rain gardens on Main Street in downtown Lafayette and in the parking lot of Purdue University’s CoRec Center. 

Bioswales

Bioswales are vegetated drainage channels consisting of grasses, flowers, and shrubs that encourage stormwater runoff to infiltrate along its path to a drain or inlet. 

An example of a large-scale bioswale is along Veteran’s Memorial Parkway on the south side of Lafayette. The bioswale runs from Ninth Street to State Road 52 along the south side of the Parkway.

Pervious Pavement

Pervious pavement has intentional spacing or channeling between bricks or pavers for water to flow down through as it infiltrates into the ground. Pervious pavement can be used for driveways, patios, streets, or sidewalks where concrete or asphalt is used.
