Brush Hill Dam

DuPage County Forest Preserve District

BLA prepared a Dam Inspection Report according to the requirements of the Forest Preserve District of DuPage County and the IDNR-OWR “Guidelines and Forms for Inspection of Illinois Dams.”  The Design Report that accompanied the Dam Inspection Report addressed the issues relating to the rehabilitation and total replacement of the dam.  Preliminary investigations of the upstream face of the earth embankment demonstrated failed slope stability and erosion.  The plan for rehabilitation included routing a walking path up to the dam and over the spillway structure, bioengineering, erosion control and dewatering/cofferdam recommendations.
