"Only half the wall is on my property and the other half is on someone else's property," he told the council.
Shields said a field survey has not been done to determine where the plugs actually sit in the wall. The buckling also has left it far from its original position, further complicating the matter.
"Without physically knowing actually where those plugs are or where they were in their original positions, there's no way to be certain," he said.
But Shields said it would be unusual for the property line to be in the middle of the wall and that it was more likely to be at the base.
Fuller also presented information from several historic documents that discusses the issuance of a bond by the town to build a sidewalk in 1911, reinforced by a stone wall.
Fayetteville Mayor James Akers still says there's no documentation that the wall belongs to the town, but that it would continue to try to find a solution.
Harrah, the town attorney, said officials didn't want to be contentious, but that their experts are telling them the wall isn't the town's.
"That's not saying we're not going to work with folks, because we understand the tremendous financial burden that will be placed on townspeople to fix those walls. So we're going to do what we can to help too," he said. "We don't want to get in a big battle over these walls. We want to save them like everybody else."
