You can prevent Runoff problems!

Reduce Pollutants in Runoff By: • Store chemicals in Secondary containment • Properly clean chemical spills immediately • Wash vehicles at a commercial car wash facility • Dispose of animal wastes properly • Clean yard debris from paved surfaces

Example of sediment barrier Manage Runoff Around Your Home By: • Seeding and topping bare soil • Placing sediment barriers • Minimizing paved surfaces • Diverting stormwater from basement windows • Directing roof drainage onto lawn or garden • Landscape to slow water flow
