Stormwater

What is Stormwater?

Stormwater is rainfall and melting snow that soaks into the ground or runs off surfaces into storm sewers and nearby waterways. As natural landscapes are turned into roads, sidewalks, driveways, parking lots and buildings, these surfaces limit the ability for water to soak into the ground which leads to increased stormwater runoff.  As it flows over these surfaces, stormwater can become polluted as it picks up, carries, and transports various pollutants including road salts, garbage, fertilizers, pesticides and oil. 

What is Stormwater Management?

Stormwater management is the effort of reducing runoff and improving water quality in urbanized areas. In more rural settings, storm water management includes culverts and ditching.
