Causes of Flooding


If Charleston is to be resilient to future flooding, we must commit to understanding the multi-faceted problem. We know the issue is not only related to sea level rise. The amalgam of causes also includes geography, frequent extreme weather-related events, increased precipitation, higher groundwater tables, antiquated infrastructure, subsidence and more.  All contributors to flooding in our city are and will continue to be monitored and evaluated.
