The project consisted of the removal of the existing, badly deteriorated and failing CMP culverts and replaced them with precast RCP culvert pipes, including restoration of disturbed areas and ancillary items.

Manhard was responsible for the removal and replacement of the existing EQRS 42” pipe culvert on Pheasant Ct. and the removal and replacement of the existing 54” pipe culvert on Clarendon Drive at the Round Lake Drain.

The culverts are located within the mapped regulatory floodplain so the proposed improvements had to be made without placing any fill within the limits of the floodplain, which created a challenge. Permits were obtained from the USACE and LCSMC because of the work performed within the floodplain and the impacts to existing wetlands.
