Georgia has and had a lot of damage, as well as inland South Carolina too; although I haven't seen much from S. Car, beyond the initial power outages. I have seen pictures of inland Georgia, and it destroyed a lot of hog barns, damaged a good number of homes, and downed a ton of trees too.
But, yes, 100%, FEMA is a tool, but it's primarily a tool to get things paid for after the fact. Your first group responsible is the state and local. Now, the small towns have no way to really deal with, so the state should have taken a leading roll. They really should have had some emergency contractors already mobilized, road base material stock piled strategically close to, but accessible from outside, near know trouble areas. The water main in Asheville, I don't know enough to comment on. Maybe the dams should have drawn down leading upto it, but the people blaming the dams are fools. Yes, opening the spill ways flooded hundreds, but if they didn't, they would have Killed thousands.
As an example, I thought it was Frances with an E, but maybe it was Mathew, or one if the others, about 7-9 years ago, a Lot of old folks died in nursing homes because of power outages. Turns out, immobile people, in 100 degree weather, stuck in bed, don't last long. Hospitals had back up generators, but many small assisted living places did not. Now they have to; and there was a surge with that new regulation in getting gas service to elder care facilities.
I dont know what the ending death toll from Helene will be, but if we count it with the deaths that were indirectly caused by it, I'm guessing it will be over 1000
