Cover photo for the document: South Carolina Dam Failure Assessment and Advisement

From October 1 through 5, 2015, heavy rainfall over parts of South Carolina resulted in the failure of 49 state regulated dams, one federally regulated dam, two sections of the levee adjacent to the Columbia Canal, and many unregulated dams. In support of recovery efforts, FEMA Mitigation deployed a team to assist in the assessments of dams and provide expertise and insights to the State of South Carolina, FEMA Headquarters, FEMA Region IV, and Joint Field Office leadership.

This report is a result of the FEMA Mitigation Dam Task Force Strategic White Paper recommendation to issue a task order under the Hazard Mitigation Technical Assistance Program to aid the recovery. The deliverables of this task order provide state and local officials with consolidated data about the 49 state regulated dams that breached during the flooding event which resulted in disaster declaration DR-4241-SC. This data can be used to identify potential Hazard Mitigation Grant Program projects. It can also inform land use decisions, and may impact other comprehensive recovery options that consider vulnerable critical infrastructure and high value mitigation targets.
