The Illinois Department of Transportation maintains a chartered Stormwater Committee composed of members from a variety of backgrounds and individuals from other state agencies to help inform and guide policy creation, advise IDOT staff on stormwater issues should they arise, and oversee erosion control training for staff and consultants. The committee also regularly coordinates with other stormwater groups and initiates research through the Illinois Center for Transportation to study aspects of the stormwater management program and determine whether improvements can be made to best management practices.
IDOT will implement a Special Provision for plastic-free Erosion Control Blankets in August 2025 along with updated guidance in the IDOT’s Bureau of Design and Environment Manual. In addition, IDOT has finished research on native vegetation mixes that may potentially expand the use of native species on IDOT right-of-ways.
