Best Management Practices (BMPs) There are a variety of practices available to manage stormwater depending upon a variety of factors. What is the management goal? What are the site conditions like? How large is the watershed area? What are the downstream receiving waters? All of these questions should be considered when deciding which practice or practices to use. Best management practices general fall into three categories: detention, filtration and infiltration.
A rain garden is designed to make use of rain and stormwater runoff form adjacent structures. Rain gardens differ from other types of gardens in that soils are engineered and plants are specifically selected to mimic a healthy forest.
Rain barrels collect and store rain water from a roof top for later use. Residential rain barrel designs are easy to make yourself. They typically have an opening at the top to allow water from the downspout to enter, a lid, an overflow pipe, and a spigot at the bottom of the barrel.
Pervious pavement allows rain water to infiltrate the ground before it runs off into the storm drainage system. This technique may be used for low speed and traffic areas such as walkways, patios, plazas, driveways, and parking lots.
