After carefully examining
bkcummingham1’s photo and the Lady Lake and Sumter property records, there is not a shadow of a doubt in my mind that the wall is on the property owned by Gary Morse’s company.
The key to the puzzle is the golf cart roundabout made of pavers that is on the Tri-County Medical property. In the picture taken from the Orange Blossom side we do not see the pavers. If the wall had been put in by Tri-County Medical, the picture would have shown most if not all of the roundabout.
In the meantime, I’ve started a new thread with a potential workaround.
Have a look see if you are impacted by the wall.
