YORK, Pennsylvania - Baltimore District awarded an emergency contract Monday, July 30 in the amount of $357,846 to Cromedy Construction Corp., a small business headquartered out of Philadelphia, for work to repair the area of channel wall that collapsed along Codorus Creek July 26.
Work will entail removal of the currently unsupported concrete slab that sits atop the masonry channel wall, as it presents an access and safety hazard for workers who will repair the wall; excavation of the soil adjacent to the wall; installation of features to allow the ground to drain to prevent further erosion; and cleaning and repair of the fallen channel wall materials. Work is anticipated to start this week.
The District will continue to monitor the site and anticipated precipitation, and continue to lower the reservoir level at Indian Rock Dam.
Gate operations continue at the dam to reduce the reservoir level to create more space for flood control, while also considering impacts to downstream communities. Gate operation modifications will continue as downstream conditions allow. The dam’s flood control capacity is currently at approximately 28 percent.
The Corps is working closely with York County Emergency Management and Pennsylvania Department of Transportation, as well as other agencies and local officials.
The masonry channel wall is part of the Codorus Creek flood risk management system that is operated and maintained by the Corps; however, the wall is not part of a floodwall or levee. It abuts existing high ground along the channel. The wall’s purpose is to keep the water within the channel and to protect against erosion and scouring. Therefore, this collapse does not increase flood risk to the community.
