Both Chattanooga G&CC (Ross, 1922) and Pinetree (Kennesaw, GA, Chick Adams, 1962) have recently been completely renovated by Bill Bergin. Bill's work at Chattanooga has gotten a fair amount of national attention because of the Ross connection, while Pinetree is very well-known in GA due to having hosted several GA Opens and serving as a qualifying site for the US Open.
BTW, the work at Chattanooga was done with only some aerial photos but no Ross plans to work from. Bill was able find many of the original bunker sites, and so forth, so it was a combination restoration/renovation. Pinetree was of a complete overhaul and updating. I think it is safe to say that the members at both clubs are ecstatic at how their courses came out.
The link below will take you to some very interesting before and after pictures of the two courses, in which you see the "after" picture, but can switch back and forth to the "before" simply by moving the mouse over the picture. Very cool presentation, I think. Enjoy.
