The Village’s Board of Trustees awarded the construction contract for the subject project to Earthwerks at the September 10, 2019 Regular meeting. The project involves the removal of the invasive and volunteer trees, restoring the bottom and side slopes of the reservoir with wetland and native plantings to enhance low flow drainage and prevent the build-up of silt in the storm sewer segments that discharge into the basin, which reduces their conveyance capacity. The detention volume of the reservoir will also be increased from 74 to 84 acre-feet. The project will also include the replacement of the three high-flow pumps and one low-flow pump, all of which have reached the end of their useful service life. Please refer to the Project Exhibit.
The Village has retained the firm of Christopher B. Burke Engineering, Ltd. to be the construction manager for the project. Construction is anticipated to start this week and be completed before the end of the calendar year, with the exception of the native landscape plantings which will occur in the spring.
If there are any questions, concerns or additional information needed regarding the project, please contact the Engineering Division at 847/918-2100.
