Environmental and Stormwater Management
Stormwater quality is very important! The County’s stormwater program helps to keep our waterways clean and healthy. The County ensures that pollutants do not leave construction sites, prohibits illicit discharges and educates the public and local businesses on what they can do to help.
Please contact the Environmental Manager at 720-874-6525 for more information and to review the County’s stormwater quality program description document (also known as the County's municipal separate storm sewer system permit or MS4).
What is Stormwater Pollution?
Some rainwater and snow melt soaks into the ground, but the rest of it flows over streets, parking lots and other impervious surfaces before hitting the storm drain system, where it ultimately flows, untreated, directly int streams and lakes. Therefore, sometimes that water gets polluted. Polluted runoff is the number one cause of water pollution in the United States.
Pollution is anything that harms our environment. Sometimes the pollution is obvious, like trash floating on top of the water or paint that was dumped. Other pollutants are not easy to detect, like motor oil from a car or excess lawn fertilizer. Almost all pollutants can harm our waterways. Some also can harm wildlife and people using waterways.

If you see the following in a stream or lake:
- An unusual color or smell
- Suds when it is not raining
- Dead or dying fish or other aquatic life
- Items that have been dumped in the waterway
- Anything else that does not look or small normal
There are approximately 1.4 million dogs in Colorado. Did you know that equates to about 390 million pounds of waste each year?! Please SCOOP THE POOP.

Follow instructions on the label!
This is critical. Excess lawn fertilizers, herbicides and pesticides on lawns and gardens can wash into waterways during a rainstorm. The impact of that is great. It can cause algae blooms in streams and lakes, robbing the aquatic life of oxygen.

Oil, paint, chemicals
Stormwater is not treated and flows directly to streams and lakes. Do not throw anything down the storm drain. Please recycle as much as possible and properly dispose of household hazardous waste, such as paint, automotive batteries and used oil, and household chemicals.
Grass, leaves, landscape debris
You may think grass clippings, leaves and other landscape waste are no big deal because they are natural. Well before you pile it up or blow it out on the street, think about this...If not properly disposed of, this common outdoor waste can actually cause big problems. When piled up in the street, it can cause flooding issues on neighboring properties or if it makes it to an inlet or stream bank it can deposit nutrients that cause algae blooms. Please compost or trash this common backyard waste.
Put a lid on it! Make sure all outdoor garbage cans and dumpsters stay tightly covered. Wind can blow and stormwater can wash trash and debris into storm drains which flow untreated to our streams and lakes.
