New here, first post, have been following events and pondering. My thoughts: With all the talk of tunnels and basements and checking of permits it would make sense to look at this from a straight up construction point of view. If the intent of the project is to do something this sinister and obviously illegal then the normal permitting and construction code process should probably be eliminated as much as possible. And if you have connections and cash many things can get done on the down low, as in who ever actually looks at the jobsite permits that need to be posted and other such things, by that I mean the average person just walking by a jobsite.

I used google earth to take a look at the CPP site and went through the historical imagery available there. There are two things that strike me as somewhat odd, they are as follows:

Consider that the whole strip mall is apperently built on a thin layer of fill material at what appears to be the head of a shallow creek bed.

There is a picture of trench work being done ( at CPP I believe) that is in the shape of a "Y" with what appears to be a run of pipe exposed somewhat (it looks like trenchwork not tunneling, hear me out, please). If you look at the latest satelite imagery there is somewhat similar "Y" shape shadow image on the roof at the rear of the building, this suggests settling of the exterior walls ( which support the roof), the slab most likely is independent of the walls since the walls are brick I believe, where the trench penetrates the wall subgrade it will most likely cause settling of the non-native fill material and the brick wall above it. The trenchworks appear to be of a drainage system. This end of the building also appears to be at a lower finished grade than the street level entrance end of the building. Changes in elevation like this can create ideal situations for other spaces that are not readily noticeable.

Looking at the rooftops of the immediate strip mall complex there looks to be a continuous fault line running at about the 55' line measured from the front of the building. Note that it terminates at CPP at the north end and the large building 8 addresses down towards the SXSE end. There seems to be something going on subgrade, also note that i took shadowing into account, such as trees and powerlines.

Anybody with access to better imagery may see much more and confirm or deny what I think I see on normal civilian google earth.
