What is Stormwater and Stormwater Runoff ?
Increased risk of flooding
Stormwater is any precipitation from a storm event ( rain , snow , sleet , etc ).
Stormwater runoff is any precipitation that does not soak into the ground but instead runs off its surface . Non-porous or impervious surfaces such as driveways , sidewalks , and streets block precipitation from soaking naturally into the ground . Stormwater can carry and deposit chemicals and other harmful substances into surface-water bodies .

High intensity thunderstorms and snowstorms are common in North Central Texas . Because urban areas have many impermeable surfaces , large volumes of water can enter the MS4 .
During a rain event , thousands of gallons of water must be transported away from the street as quickly as possible . If the MS4 is clogged with debris , storm systems can become blocked and overflow . Flooding can lead to loss of life , property and infrastructure damage .
