As our Seas Rise, the Future of our Coast Hangs in the Balance.
Coastal Georgia’s barrier islands and historic, low-lying communities are particularly at risk. As our seas continue to rise, we can expect to see:
Loss of Habitat: Sea level rise will impact natural areas by flooding beaches and salt marshes, causing westward migration of these habitats. Unfortunately, the migration of these habitats will be impeded by manmade structures along the coast.
Coastal Erosion: Increased sea level exacerbates flooding during storm surges and King Tides by raising the water’s starting point (i.e. mean tide level). We can expect to see worsening erosion of protective barriers like sand dunes and further inundation of floodwaters.
Public Safety and Infrastructure: Our coastal communities will face impacts to our built environments, including public infrastructure, private property, and public safety. When we choose to invest in coastal development without considering resilience, we continue to invest in infrastructure that is incompatible with the future of our coast. Roads, municipal sewer systems/septic tanks, and drinking water wells are just some of the infrastructure threatened by sea level rise.
Even Georgians who do not live along the coast will feel the impacts from sea level rise. Nuisance flooding will become more common, impeding daily routines and commutes. As storms increase in intensity and frequency, storm surge during hurricanes will inundate further into our communities, making their impacts more severe. The cleanup from storms is paid for through tax dollars from all residents, not just those living along the coast.
