I own one of those lots that never was owned by either Alabama Power or Russell and had similar title history to yours...I was advised by the attorney that developed our subdivision that APC had no control over anything 491 (490 at the time) and above. Approximatly 5 years ago I was building a small building within 2 feet of the 491 line to store lake toys, etc.. APC shoreline rep came by and asked if I had a permit from them to build. I informed him that I did not need one as they had no jurisdiction above 491 for the reasons previously mentioned. The conversation was cordial, the APC shoreline rep did not contradict my position, and I never heard from them again. I can assure you from personal experience with APC shoreline permitting people, that if they felt that they had authority to require a permit for my storage shed, they would have pressed the issue and required a permit...which they did not.
