CHICAGO DEPARTMENT OF TRANSPORTATION ROADWAY PLANT LIST

The Chicago Department of Transportation (CDOT) Division of Engineering is pleased to present the newest edition of the City of Chicago’s Roadway Plant List, intended as a resource for landscape architects.

CDOT has evaluated the plants on this list based on its years of experience maintaining medians and other roadside locations. The accompanying comments are based on the plants’ ability to withstand salt spray and other urban roadway conditions. Although no scientific trials were conducted, installation and maintenance of the plant material have been done in accordance with standard CDOT specifications. As a result, cultural conditions such as soil structure, composition and moisture are known factors.

CDOT’s list highlights plant materials in order of consideration. Dark gray rows indicate plants that are not recommended. Light gray rows include plant materials that are currently under evaluation or have not yet been used. It also indicates plant selections which survive in the roadway but have attributes which negatively affect the plant’s performance in a municipal application. Although the “concerns” are independent of CDOT’s assessment of the plants’ sustenance in the roadway, CDOT expects selections to consist of plants that both survive on medians and have no additional concerns.

We hope this guide proves a valuable tool for industry professionals. For more information, please contact CDOT’s Division of Engineering at (312) 744-3520.

Daley, Mayor has limited its use of chemical herbicides; hence the existence of dandelions Thomas H. Powers in the boulevards. Acting Commissioner
