Flooding and Extreme Weather

About Flooding and Extreme Weather in South Carolina

Coastal South Carolina is particularly vulnerable to flooding, whether from extreme weather events or from the effects of sea-level rise.

The S.C. Sea Grant Consortium assists with community efforts related to flood preparedness and resilience, and research into the prevention of flooding.

Assessment of Water Infrastructure Vulnerability in Coastal Cities

The S.C. Sea Grant Consortium with other partners developed a method and guidance for assessing the resilience of public water and wastewater systems to flooding as well as the access to health care facilities to improve the health outcomes of communities when faced with tropical storms, increased tidal flooding, and extreme rain events.

South Carolina Guide to Beachfront Property

This guide for current and future S.C. beachfront property owners was produced by S.C. Dept. of Health and Environmental Control’s Office of Ocean and Coastal Resource Management with significant contributions from the S.C. Sea Grant Consortium.

Current and prospective homeowners will learn about common coastal hazards, such as chronic erosion, storm-driven erosion, and flooding. Also included are important state regulations for construction and renovation of properties on the beachfront and criteria for repairing or rebuilding after a storm event.

Flood Preparation, Response, and Recovery

SCCIN Flood Resources Guide

The South Carolina Coastal Information Network (SCCIN) Flood Resources Guide is a well-organized PDF guide that provides residents of coastal S.C. complete lists of resources on how to prepare for, respond to, recover from, and adapt to flooding.

Charleston Resilience Network

The CRN is a collaboration of public, private, and non-profit organizations in the Charleston, S.C. area. The mission of the group is to work collaboratively to increase the community’s ability to respond and adapt to adverse weather and climate conditions.

Tidal Flooding Resources
