Summary
The City of Dearborn is soliciting bids for the Colson Palmer 12ft Storm Line Rehabilitation Project (ITB-R000905, 2025-019), an Invitation to Bid (ITB) covering the installation of one dewatering pump station, removal and replacement of four backwater flap gates, and cleaning of 9,163 feet of sewer in the Colson Palmer 12FT Storm Line. The 12-ft diameter, 1.97-mile-long trunk storm sewer runs from the Colson and Palmer intersection through central Dearborn to the Rouge River outfall, where rising water levels and sediment accumulation have reduced its open area and capacity. The project aims to restore conveyance capacity, mitigate flood risk, and improve stormwater management for Dearborn residents.
