re: Buckhead pushing to split off from the declining city of Atlanta

I think Sandy Springs was unincorporated like Central or St. George in Louisiana.

Baton Rouge is absolutely being unreasonable in their position on a neighboring unincorporated community seeking incorporation. Communities incorporate into their own municipality all the time. That's not really controversial despite what the media and the city of Baton Rouge says. If they had annexed the area decades back, their position would make sense. But they didn't, so it doesn't.

Buckhead is a different scenario if it's actually part of another city. I don't think I've seen a place de-annex before outside of the Memphis area. Is there any legal precedent for that in Georgia?

Best of luck to them.
