Stormwater Management
When it rains, water washes over our roofs, driveways, sidewalks and other hard surfaces. Along the way, it can pick up a variety of pollutants, such as pesticides, oil, metals, chemicals and soil. This polluted stormwater eventually drains into our rivers and streams. The pollutants can endanger the water quality of our waterways, making them unhealthy for people, fish, and wildlife. Runoff from our homes and driveways also causes erosion, increases river temperatures and decreases groundwater recharge. Better management of stormwater helps us protect our streams and rivers. The Backyard Habitat Certification Program will help you identify green strategies to address stormwater on your property.
