Stormwater runoff is precipitation that falls onto impervious surfaces such as roadways, driveways, parking lots and rooftops where it can accumulate pollutants, such as sediment, fertilizers, chemicals, oils, pet waste and trash. Instead of being absorbed into the ground, stormwater moves over these surfaces and makes its way into the drainage system and eventually into the Yampa River and its tributaries.
Unlike sanitary sewers that carry wastewater to treatment plants, storm drains like these convey stormwater directly to rivers, ponds, and streams without treatment.
It is illegal to dump or discharge pollutants into waterways Illicit Discharges may include fuel and chemical spills, hazardous material dumped along a roadway or into a storm drain, leaking dumpsters, discolored or foul smelling water, improper washing of concrete trucks, power washing to storm drains or waterbodies, leaking sanitary sewers, and other possibilities.
The city administers a municipal stormwater program in accordance with its Municipal Separate Storm Sewer System (MS4 Permit), to protect local waterways from pollutants found in urban stormwater runoff.
Program elements include:
