Title
153rd Street and Ravinia Avenue Roundabout - Utility Discussion
History
The Village is advancing a project to convert the 153rd Street and Ravinia Avenue signalized intersection into a roundabout. Phase I Preliminary Design Engineering was previously completed and approved by the Illinois Department of Transportation (IDOT). The project is currently in Phase II Design Engineering and it's anticipated that construction will start in late 2026. This discussion is intended to confirm a direction regarding the relocation of Village utilities in the project area.
There are four existing Village utility lines in the proposed roundabout footprint: two 12" water mains, a 36" water main, and a 36" storm sewer. Three options are being considered.
1) Leave the utilities in place - $0 in additional design and construction costs
2) Relocate the two 12" water mains and the 36" storm sewer - $200,000 in additional design and construction costs
3) Relocate all four lines - $800,000 in additional design and construction costs
Without the relocation of the utilities, the total cost for construction and construction engineering is an estimated $3.5 million, with approximately $2.3 million of that being covered with secured grant funding. Additional grant applications in the amount of $1.8 million were submitted to the State of Illinois and staff is waiting for a decision. The costs for relocation of the Village utilities would all be borne by the Village.
