Water Quality

CDOT's Water Quality Program's mission is to: •Ensure the quality of stormwater runoff is protected while Colorado's roadways are constructed, operated,and maintained; •Promote innovative best management practices; •Provide effective water quality education to CDOT staff; and •Facilitate cooperation between CDOT, watershed groups, other Water Quality Program Managers, businesses, and the public. Please note, CDOT has recently moved its Headquarters and Region 1 HQ to: 2829 W. Howard Place, Denver, CO 80204. Please update this address change in all documents that still have the old CDOT address (4201 E. Arkansas Ave. Denver, CO 80224) in them. All documents with the old address are still official and good to use. Thank you.
