When it comes to sea level rise, South Florida has good reason to be concerned. According to the Unified Sea Level Rise Projection Southeast Florida report, sea level rise along South Florida’s coastline is projected to be from 31 to 81 inches by 2100. This amount of sea level rise could easily push sea water inland and flood coastal areas more frequently and for longer periods of time. The Biscayne Aquifer, which consists of highly permeable limestone rock and provides fresh drinking water to the 8 million residents of South Florida, lies at shallow depths making it particularly prone to saltwater intrusion.
