The City is currently under agreement with IDOT to maintain 80 of the traffic signals in the City that are located on State Routes. In putting the project together, City Engineering estimates the retrofit work to cost about $5,000 per intersection for a total of $400,000. The State's portion of the project is estimated to be approximately$221,000 and the City's portion will be $179,000. The State will also share proportionately in the cost of the LEDs the City will purchase with a partial grant from the Illinois Clean Energy Community Foundation. The purchase of the LED Lamps will be approved by another Council action. Staff is currently working with IDOT to advertise a LED Conversion project for competitive bid. Bids should be brought before Council within 60 days. The LED upgrade work must be completed by June 30, 2008. POTENTIAL OBJECTION: There are no known objections.
