Reducing pollutants in runoff • Pesticides and chemicals • Pet and animal wastes • Automotive wastes • Winter salts and deicers • Grass clippings and yard wastes • Controlling runoff • Preventing soil erosion • Minimizing paved surfaces • Basement flood protection • Roof drainage • Landscaping
StormwaterConcerns • Sediment • Nutrients • Hazardous chemicals
StormwaterWater from rain or melted snow that does not soak into the ground RunoffFlowing stormwater that picks up soil, pet wastes, salts, fertilizers, pesticides, oil, grease, yard wastes, litter and other pollutants Becomes But where does it all go? To our Streams, Lakes & Rivers
What’s the Result? • Bacteria and parasites from animals wastes • Drinking water contamination • Basement and lower level floodings
Ecological Concerns • Degradation of lakes, rivers and wetlands • Algal growth from inputs of phosphorus • Loss of habitat due to cloudiness of water • Toxic chemicals threaten aquatic life
STORM DRAINS collect more than rainfall...
Reduce the amount of runoff. * Minimize amount of Pavement. * Serpentine or traversing pathways.
Painted by Michigan artist Ruth Zachary * Plant a Rain Garden! • Native soils, flowers and vegetation • Reduces runoff from roofs or impervious surfaces • Infiltrates rain water so garden is dry between rainfalls • Low maintenance • Provides habitat for native wildlife
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
