Muskingum Watershed Conservancy District
Black Fork Subdistrict Flood Control System
EMH&T is working with the Muskingum Watershed Conservancy District (MWCD) and a group of local stakeholders to develop recommendations for structural and non-structural flood control measures within the Richland County portion of the Black Fork Mohican River watershed. The City of Shelby and surrounding areas of Richland County have experienced repeated and damaging flood events associated with the Black Fork for decades. Recently, the City has gained notoriety for implementing an aggressive flood hazard mitigation plan which focused on acquisition of flood prone properties for conversion to beneficial public open space within the community. The next phase of the project is identifying preferred options for using regional detention basins, channel improvements, and bridge replacements throughout the watershed to reduce the potential for flooding. In addition, we are investigating opportunities for agricultural best management practices (BMP) to address channel bank erosion and other non-point sources of water quality impairment within this area The project also includes a process to gain public support for the watershed-based solutions toward the goal of implementing a program for funding the improvements. The analysis of flood protection measures is based on a HEC-HMS model of the upper Black Fork River watershed which was developed and calibrated by the U.S. Geological Survey (USGS), as well as a HEC-RAS model of the Black Fork mainstem and tributaries also developed by the USGS.
