Why Reducing Runoff Matters
Suburban and urban areas are the fastest growing source of stormwater runoff affecting the health of the Chesapeake Bay. Homes, driveways, sidewalks and parking lots prevent rainwater from filtering into the soil before reaching storm drains and streams. Runoff from storms picks up many pollutants like pet wastes from lawns and vehicle fluids from driveways. The rushing water erodes stream banks and carries sediments. These sediments and pollutants hurt water quality and harm wildlife. For towns that get drinking water from lakes and rivers, the pollutants can be very costly to remove. Plants and soils do a remarkable job of cleaning water and can be used in our landscapes to reduce runoff and provide clean water.
