As rain falls and washes over rooftops, streets, and parking lots, it collects dirt, trash, and other pollutants and often carries them into nearby rivers, lakes, streams, and oceans. Consider taking steps to reduce the amount of stormwater runoff from your facility.
- Sweep sidewalks and other pervious surfaces instead of washing with a hose
- Consider permeable surface alternatives to conventional asphalt and concrete
- Maximize other permeable surfaces and vegetated areas such as rain gardens, lawns and landscaped areas
- Consider planting grass and trees on rooftops

In many parts of the country, urban runoff is the single greatest source of water pollution. In addition to dirt and debris, urban runoff can include such toxic components as oil and heavy metals like lead and mercury, in addition to any other pollutants that might find their way onto roads and rooftops. These pollutants can have a negative effect on drinking water supplies, recreation, and wildlife. By taking steps to minimize urban runoff, your team can help to reduce these negative impacts.
