Businesses can adopt good storm water management practices to reduce non-source pollution. Three ways to do so are:
Rain gardens are created in a low spot of a property and designed to catch storm water runoff from structure downspouts, driveways, parking lots and/or roads. These gardens are planted with deep-rooted plants that thrive on and absorb water, and native plant use is encouraged. The garden serves as a means of slowing the movement of water, which helps reduce flooding, and it also helps clean the water before it gets to a waterway.
Rain barrels are used to catch and hold rainwater and are attached to downspouts. Using one or more rain barrels can help reduce flooding and drainage problems by reducing the amount of water flowing onto properties or into waterways during the storm event. Capturing rainwater to water gardens during dry spells. Rain barrels can be purchased at some lawn and garden stores or can be made from items found at the local hardware store.
Green roofs are accomplished by growing plants on rooftops, thus replacing the vegetation that was eliminated with the building was constructed.
Advantages to green roofs:
Green roofs can slow storm water during wet weather, reducing the possibility of flooding and drainage problems on the surface below.
Green roofs provide excellent insulating properties for a building, helping keep buildings cooler in the summer and warmer in the winter.
Green roofs also help reduce urban heat island in cities like Indianapolis. Heat island are urban areas in which the temperatures are higher than surrounding areas due to the removal of vegetation and high energy usage.
Green roofs also help filter and clean the storm water coming off of roofs before it enters a waterway.
