The important project to mitigate the flooding problem at Deerpath and Rte. 41 is scheduled to begin and will be funded by the Illinois Department of Transportation (IDOT) at a cost of $12,127,335.  The project is expected to be completed by December of 2022. 

A new pumping station will be constructed at the southwest corner of Ahwahnee Lane and Deerpath Road.  The current equipment, initially installed in 1951, has been malfunctioning for years and must be replaced.  At the same time, new storm sewers will be installed and two detention ponds will be created on the Deerpath Golf Course.  In addition, both lanes on Deepath under Rte. 41 will be widened, and two dedicated left turn lanes will be created to improve safety and the flow of traffic at the intersection. 

Signage will be installed throughout the area within the next week.  Beginning on Monday, November 30, preparatory tree removal will begin.  The City is working with IDOT to ensure that heritage trees in the area are protected and preserved to the extent possible.  Excavation of the two ponds is anticipated to begin on or about December 7.  At that time, flaggers will be present to direct trucks entering and exiting Deerpath Golf Course.  Work will take place from 7 a.m.-7 p.m. on weekdays and from 8 a.m.-6 p.m. on Saturdays and Sundays.

The City appreciates your patience and understanding during this disruptive period.  However, residents and affected institutions (Northwestern Medicine Lake Forest Hospital, Deer Path Middle School, Faith Lutheran Church, Deerpath Golf Course) should expect traffic delays.  Please check the City’s website, social media outlets and the City’s E-News for updates.
