I assume you have no intention in updating the wiped down projects (basically Long Lake) yourself. A possibility could be to paste the few buildings that make them up again on the new terrain, even if they end up open for being updated/redone. Having said that, if we were to take option 1, what will the new area be left as? Currently it is placeholder forests, which are not particularly valuable, but more than a wool desert. Would you add some short of placeholder forest back into the area? Terraform it yourself up to our current standars (I guess this is not the idea given that you mention Carc's plans on the area)? Would the area be left as wool for someone else to eventually terraform?
I don't want you to feel pressured into having to more than double the size of your terra immersion, I'm not suggesting that. But given the huge area that you have highlighted I think it's important to discuss at what state is it gonna be left as. While I understand your workflow and thought process, I can also understand the complains of those who wouldn't want the heart of the North to be left us a green wool patch waiting for someone to do it.
Also, in case it needs to be said, I don't think leaving the Long Lake untouched is an option, given that it would make us basically unable to adress the canon about the White Knife.
