The Lake County Stormwater Management Commission has spearheaded coordination between the local sponsors including the Warren Township Highway Department, and Wildwood Park District to establish the Wildwood Area Stormwater Infrastructure Improvements Project. The Wildwood Area Stormwater Infrastructure Improvements Project is located in Warren Township and is being supported, in whole or in part, by federal award number SLT-3381 awarded to the State of Illinois by the U.S. Department of the Treasury. This funding is being administered through the Illinois Department of Commerce and Economic Opportunity Stormwater Capital Improvement Program (DCEO-STOCIP).  The proposed project achieves flood protection up through the 50-year event and significantly reduces the flood impact for larger events within the Wildwood and The Willows of Grayslake subdivisions.  A County road and 4 Township roads are frequently subject to flooding and closure as well as 109 primary structures and 106 secondary structures.  The scope consists of the construction of a secondary storm sewer extending from the Greentree Road/Winnebago Drive intersection and discharging into the drainage way adjacent to the Meadowbrook Estates Subdivision, in addition to a new storm sewer between Manitowoc Court and Royal Oak Lane.  Related ancillary work includes restoring and replacing roadway as well as roadway drainage structures, adjacent appurtenances, earth excavation, grading, and shaping of swales. Additional project features include modification to the Valley Lake outlet structure to minimize clogging potential, enhancement to the Valley Lake berm along its northern shore and water quality enhancement measures along the southern end of Valley Lake including plunge pool improvements and porous parkways along Mill Road and Greentree Road.  Please refer to the attached map for project locations.

Construction of the project’s primary infrastructure is planned to begin Summer 2023, with a completion date of Summer 2024. Infrastructure servicing The Willows of Grayslake subdivision may not be completed until 2025.  Please note – If we are awarded additional grant monies from DCEO-STOCIP, those additional funds will cover the resurfacing of the roads.  If we do not receive additional funds, the resurfacing portion of the project will be paid for using Warren Township Highway Department funds.

We have scheduled a project information open house on Monday, June 5, 2023 from 4:00 pm until 7:00 pm. The open house will be held at the Stormwater Management Commission – 500 W. Winchester Road, Suite 201, Libertyville.  We strongly encourage residents to attend the open house so you will be well informed about the improvements.
