I realise this is kind of a niche question and I’m also not personally affected. I just find it interesting from a legal perspective. So, how does this work? Do the land owners keep their ownership of the land? And if so, are the estate borders then projected upwards to the new surface area? Or does the land fall to the state (maybe with potential compensation)? I guess the land is unusable for the forseable future, because it wouldn’t be economically viable to cover the cost of clearing the space from all the rubble. Any ideas?
