I know very little about the Georgia coast specifically, but I'd say In any low-lying coastal area, but especially a hurricane-prone one, the higher the elevation above sea level, the better. Wind damage is plenty bad in and of itself, but the areas completely devastated by hurricanes are those inundated by the storm surge. I personally expect that sea levels will rise more and more rapidly as time goes on from climate change, and many low-lying coastal areas will become submerged. Even if storms themselves don't get any worse, a higher sea level means that the same storm will food more land. River flooding is also a major issue, both from hurricanes and other heavy rain events. Floods are getting worse from a combination of heavier rain events, degradation of the soil in the watersheds which leads to less absorption of water and more runoff, channelization and loss of wetlands in the floodplain. Elevation makes a huge difference. Where I'm at in Missouri, we just went through record flooding, 100+ year-old houses that had never flooded before were washed away. However, the community that I live in came through just fine, as we have no important infrastructure in the floodplain and also have pretty well-drained soil.
