Current Project Updates

September 15, 2017

This week, the Village’s contractor continued earthwork at West Park (1730 Pfingsten Road) in anticipation of constructing the new stormwater detention basins and soccer fields. Next week, sewer crews are scheduled to begin placing storm sewer starting at the south end of West Park. Additionally, an existing water main at the south end of the park is scheduled to be lowered. At this time, there are no road closures on Koepke or Keystone Roads due to scheduled construction.

Previous Project Updates

September 8, 2017

This week, the contractor began re-grading portions of West Park for creation of the stormwater detention. This project is scheduled to be completed in November.



September 1, 2017

This week, the Village’s contractor began mobilizing earth-moving equipment to regrade the West Park open areas for stormwater detention. On Monday, crews removed trees located in an area where they could not be saved, due to the change in the grade of the expanded West Park detention basin. Staff worked with the Park District to establish a landscape plan for this project that includes a “tree for tree” replacement of those removed trees. Crews also installed tree protection and silt fencing for tree protection and erosion control. This project is scheduled to be completed in November, weather permitting.


August 25, 2017

As part of an effort to help alleviate flooding on Keystone Road and Chartres Drive following major rain events, the Village’s contractor will begin construction of the Keystone/Chartres stormwater project. This project involves installing a new, low flow storm water system from Keystone to West Park. The project will improve flooding conditions on Keystone and Koepke Roads. Staff anticipates that the Village’s contractor will begin initial work next week installing construction fencing and removing trees, with detention basin grading beginning immediately after Labor Day.
