Stormwater is rainwater or melted snow that runs off streets, lawns and other sites. When stormwater hits vegetated surfaces and is absorbed into soil, it is filtered and ultimately replenishes aquifers or flows into streams and rivers.  Unfortunately, urbanization reduces permeable surfaces which results in more water that runs across the landscape while picking up pollutants that are then conveyed into local waterways--UNTREATED.

The following animation graphic was designed to illustrate what happens with impermeable surfaces and what you can do to reduce the amount of polluting stormwater that enters our creeks and lakes.
