Thanks for the report!
I don't know what Seaside will do about the walkovers. Someone posted that they may not rebuild all of them and just have one on each end. My guess is that they're looking into aluminum removeable ones like many others are doing, including WaterColor.
Personally, I think it would be a travesty not to rebuild them. I don't live or rent there, and if I did, I would feel even more strongly about rebuilding. I understand that the Natchez stairs were unique and very expensive to build so I might consider rebuilding "normal" stairs there.
Seaside and the homeowners association should rebuild all of them, no matter how often they need to be done, and consider it a cost of doing business. And what a profitable and unique business it is.
I would be interested to hear other's views, especially homeowners. And updates.
