The site plan was posted today to the AULCC page. The elevations show it as 770 feet 6 inches, but it drops down maybe another foot below the zero line at grade. I don't have a way of measuring that distance since there's no other height to compare it to, so unless someone has a way of measuring it with a PDF reader, we'll just have to go with this height. I know there's a way to do it, and I've tried, but I wasn't having any luck with it.
One thing, though, in the project details box, it lists the height as 792 feet 6 inches. I'm not sure what the reason for that is.
