Stormwater and Drainage

Municipal city and county governments in the watershed operate under Municipal Separate Storm Sewer System (MS4) Colorado Discharge Permit System permits. Local governmental stormwater programs include public education and involvement, illicit discharge control, construction-phase stormwater control requirements, permanent stormwater quality treatment, and good housekeeping at municipal sites.

Most of the main stem of Big Dry Creek is located within the Mile High Flood District boundaries, which extend to the Weld County line.  Mile High Flood District has worked with local governments to complete a series of major drainage plans and flood hazard area delineations for the main stem of Big Dry Creek and its tributaries. These plans include information related to flood detention requirements and stream stabilization/restoration projects, along with other information.  For more information on watershed master plans, click here.
