Site work for a water / sewer project in Lake Forest, Illinois. Conceptual plans call for site work for a water / sewer project.

The Onwentsia and Poplar Roads Study Area is located in central Lake Forest in the Skokie River watershed. The area is comprised of single-family residences. It is roughly bounded by Onwentsia Road to the north, Westleigh Road to the south, Skokie River on the east, and Ridge Road on the west. Staff will work with IDOT in the future to coordinate this project schedule with their Onwentsia storm sewer project in this area which is shown currently in their 2025-2030 multi-year plan (anticipated summer FY2028 or FY2029). As possible, this project will also be coordinated with a local watermain replacement project on Basswood Road from Blackthorn Lane to Westleigh Road to minimize impacts to residents.This is the construction project-sheet, see PW-STM-02-21 for the design project-sheet. The scoresheet priority for this project is a 1 but is shown as a 5 as grant dependent (as of 10/5/24). Construction is shown over two Fiscal Years with the first year installing the storm-sewer stub at Onwentsia-Poplar during the IDOT storm sewer project on Onwentsia. The second year would be installation of the upstream storm-sewer from this stub to the south. Constructing it this way avoids digging up the same intersection two years in a row. The project is included in the City's 2026-2030 Capital Improvement Program (CIP). As of September 16, 2025, further details have not yet been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
