Flooding and sea level rise are challenges the City of Charleston has taken seriously for centuries. However, Charleston is experiencing flooding more frequently than ever.
Per NOAA tide gauge data, Charleston has experienced 13" of sea level rise in the past 100 years.
Notably, this rate is non-linear as almost 1/2 the total amount of sea level rise in the last 100 years has been in the last 20 years, (approx. 0.5 FT). That means the rate of sea level rise is increasing faster now than in the past.
The City of Charleston Flooding and Sea Level Rise Strategy update for 2023 builds upon the 2019 and 2015 Strategies, including important and updated climate data, as well as infrastructure and drainage project and policy updates. The City’s flooding, drainage, and sea level rise investments are increasing as are its climate adaptation, resilience and sustainability work.
