Floodplain Management

What the City does

Maintenance and mitigation efforts

The City inspects creeks and drainage ways each spring and summer to keep channels clear of debris. If you see debris or other blockages, please submit the concern online or contact the Streets Division at 720-898-7720. 

  • Please note: irrigation ditch maintenance is the responsibility of the ditch owner. 

Short and long range planning for resiliency

Even outside of the mapped floodplain, everyone has flood risk. The City builds and maintains storm drainage pipes and open channels to reduce flooding problems. Over time, these storm drainage systems need to be repaired, replaced and sometimes expanded. The City team creates short and long range plans to prioritize these needs around the city. 

Floodplain permits

If your property is in a floodplain, in addition to a building permit, a separate floodplain development permit may be required in order to build on, alter, regrade, or fill your property. Visit the Right-of-Way Permit page for more information.
