Keep it Clean, Because We're All Downstream!
What is stormwater?
Stormwater is water from precipitation that flows across the ground and pavement when it rains or when snow and ice melt. The water seeps into the ground or drains into storm sewers. These drains collect stormwater runoff at street corners or at low points on the sides of your streets.

Pollutants from motor oil, grass clippings, engine coolant, fertilizers, bacteria and pet waste are carried in the water through the city’s stormwater collection system. They are then discharged into to the local waterways such as 1st, 2nd, and 3rd Creek; Sand Creek; and also the South Platte River.

Impacts of Stormwater Runoff
The more development (homes, roads and business) happens, the amount of stormwater runoff increases because soil and vegetation loses its natural capacity to absorb and contain pollutants. Greater amounts of stormwater runoff can cause erosion of land areas and stream banks, increase flooding and carry pollutants to surface waters.
