ITEM SUMMARY:
The DuPage Business Park, located on the southwest side of the City of West Chicago, has seen major
developments over the past few years, which has resulted in an increased traffic volume. To protect the
safety of motorists, the City desires to install a traffic signal at the intersection of IL-38 (Roosevelt Road)
and Technology Boulevard. The Illinois Department of Transportation (IDOT) has jurisdiction over IL-38,
while the City has jurisdiction over Technology Boulevard.
In 2020, State Senator Karina Villa, as part of the Public Act 102-0017, included improvements
associated with this traffic signal to be appropriated from the Build Illinois Bond Fund via the Illinois
Department of Commerce and Economic Opportunity (DCEO). The cost associated with these
improvements is listed at $600,000.00. The grant agreement was fully executed by DCEO on September
27, 2023.
On February 21, 2022, the City Council approved Resolution No. 22-R-0010 authorizing the Mayor to
execute the initial contract with Gewalt Hamilton Associated, Inc. (GHA) for engineering services related
to Phase II — Design, which included the preparation of an intersection design study, topographic survey,
traffic signal installation plan, traffic signal interconnect plans, minor geometric improvements, and
bidding assistance in the amount of $51,950.00. On August 7, 2023, the City Council approved
Resolution No. 23-R-0070 authorizing the Mayor to execute Amendment No. 1 with GHA for the
engineering design services for an amount not to exceed $27,300.00, for a revised contract amount of
$79,250.00, to begin the detailed design of the project, including the intersection lighting, and prepare bid
documents.
Staff and GHA are having ongoing project coordination with IDOT for the involvement of the State Route
and for the use of Motor Fuel Tax (MFT) funds for the construction and construction engineering of the
project. Additional Phase II —- Design coordination, which was not initially anticipated during GHA’s Phase
ll- Design scope, is now requested by IDOT for the project to acquire final IDOT approvals before the City
can advertise the project for bids. The additional scope for GHA includes Environmental Survey Request,
IDOT — District 1 Bureau of Local Roads and Streets (BLRS) coordination, utility coordination, plan
revisions, location drainage technical memorandum, and Intersection Design Study (IDS) revisions as
required by IDOT BLRS.
