Stormwater
Stormwater runoff is water from rain or melting snow that flows over the ground. Land in a natural condition soaks up the water. In areas with buildings, roads and parking lots, the water flows over these surfaces into storm drains. Storm drains lead to streams, not to a wastewater treatment facility. Anything that goes down a storm drain goes directly to the nearest stream. Stormwater management controls this polluted runoff by sending it through the storm drainage system and then to lakes and streams. This reduces the pollution that reaches the Chesapeake Bay and helps prevent flooding.
