Here is link to a flyover of the section of Southern Oaks that is north of the Turnpike from 468 to the Bailey Rd bridge. A huge area, a lot of growth is going to occur in this area!
You can see the markings from the drilling they do at set intervals prior to construction. I've yet to figure out exactly what they are for but consistently they have done this in all the areas before they start construction. If you look at Google for Southern Oaks phases 1, 2, & 3 you can see the markings almost all equally spaced.
