Stormwater Management and Green Infrastructure Research
Stormwater runoff is one of the fastest growing sources of pollution. When rain hits rooftops, parking lots and roads instead of wetlands, forests and grasslands, it tends to run into storm drains that are directly connected to our waterways. Wetlands and other natural resources can hold excess water in place, filtering out sediment and pollutants before they reach waterways while also helping to recharge groundwater.
Green infrastructure practices mimic natural habitats and absorb excess water. This reduces the amount of pollution in our waterways. They can also help conserve water while preserving water quality. Green infrastructure practices include permeable pavements, rain gardens, bioretention cells (or bioswales), vegetative swales, infiltration trenches, green roofs, planter boxes, rainwater harvesting (rain barrels or cisterns), rooftop (downspout) disconnection, and urban tree canopies.
