Stormwater Programs

As part of the permit that allows discharges from the roadway storm drain system, CDOT has several different programs in place to make sure the amount of pollutants being discharged is reduced:

Construction sites program. CDOT assures the adequate design, implementation, and maintenance of temporary best management practices (BMPs) at its construction sites. Click here for more information on CDOT's construction sites program.

New development and redevelopment program. CDOT ensures that permanent BMPs are installed at appropriate construction site to reduce the discharge of pollutants into stormwater after construction is complete. This program also provides for maintenance of the BMPs.

Illicit discharges program. CDOT detects and removes illegal discharges to their storm drain system . Click here for more information on CDOT's illegal discharge detection and elimination program.

Industrial facilities program. CDOT requires all facilities that discharge stormwater into CDOT's storm drain system to obtain a specific authorization. The program prioritizes education to promote minimization of pollutants in the stormwater that the facilities are contributing to the system.

Public education and involvement program. CDOT conducts a variety of outreach activities for employees and the public. Outreach activities include brochures, fact sheets, posters, newsletters, workshops, conferences, and this web site.

Pollution prevention and good housekeeping program. CDOT prioritizes minimization of pollutants in stormwater by developing runoff control plans for maintenance facilities, requiring the proper application of herbicides, pesticides, and fertilizers, maintaining permanent BMPs, and operating public streets, roads, highways, and parking lots to promote both safety and stormwater quality protection.

Wet weather monitoring program. CDOT assesses wet weather impacts from highways and the performance of best management practices used to control stormwater discharges.
