Stormwater Management

Stormwater Defined
Stormwater is water that flows overland during a precipitation event and does not soak into the ground or evaporate. Paved areas, such as driveways, roof tops, parking lots, and streets contribute to the amount of storm water that flows through a city as these surfaces are typically impervious and keep precipitation from seeping into the soil and recharging groundwater supplies.

In more urbanized areas, stormwater can pick up surface pollutants. Stormwater flows into the city's storm sewer system, ultimately ending in lakes and streams, which are all affected and must therefore be managed.
