The Charleston Peninsula study is part of the U.S. Army Corps of Engineers' disaster recovery efforts funded by the Bipartisan Budget Act of 2018 (P.L. 115-123, February 9, 2018). The Charleston Peninsula study will evaluate possible actions to provide long-term coastal storm and flood risk management on the Charleston Peninsula. This study is proposed to be completed at a cost of $3 million (100% federally funded) and within three years from October 10, 2018, which is the date the agreement with the City of Charleston was signed.
The scope of the Charleston Peninsula Study is to investigate potential structural and nonstructural solutions to address coastal storm and flood risk to vulnerable populations, property, and infrastructure within the limits of the City of Charleston. The Charleston Peninsula, South Carolina has high levels of risk and vulnerability to coastal storms and flooding, which will be exacerbated by a combination of sea level rise and climate change over the study period.
The Charleston District will perform the functional activities of a feasibility-level study in accordance with USACE SMART Planning and Civil Works Modernization guidance and milestones. This planning study will address engineering, economics, environmental impacts, and NEPA compliance.
The authority to study coastal South Carolina, including the Charleston Peninsula, was provided in the Rivers and Harbors Act of 1962, P.L. 87-874, Section 100, and Senate Committee Resolution.
