Description

This layer was created by CDOT's GIS Support Unit and is updated annually using the 2010 census urbanized areas (non clusters), Cherry Creek Drainage Basin, and the most recent city limits (from DOLA) as listed in the MS4 permit.

MS4 (Municipal Separate Storm Sewer Systems) is a conveyance or system of conveyances that is: Owned by a state, city, town, village, or other public entity that discharges to waters of the U.S.; Designed or used to collect or convey stormwater (including storm drains, pipes, ditches, etc.); Not a combined sewer; and Not part of a Publicly Owned Treatment Works (sewage treatment plant).

DescriptionThis theme depicts adjustments made to 2010 Census-designated Urban Areas to include adjacent areas with similar urban characteristics, such as commercial and workplace areas or other traffic-generating locations. Adjustments are also made to smooth urban vs. rural roadway classifications where roadways may repeatedly snake in and out of designated urban areas. Adjusted urban boundaries are determined cooperatively between the Colorado Department of Transportation and local transportation planning officials and approved by the Governor of Colorado and the Federal Highways Administration. These boundaries have been subsequently modified (as of September 2015) from those adopted in February 2015 to make technical corrections for the purpose of refining urban/rural roadway transitions.
