Guilford and Forsyth officials are requesting the state to survey and mark the boundaries between the two counties to help each government determine who pays what property tax near their borders.
The Guilford County Board of Commissioners unanimously approved a resolution requesting the state to mark its boundaries with Forsyth County on Thursday. It previously adopted a border line in 1964.
According to the proposal, mapping technology changes and the removal of previous markers made the exact boundary between the two unclear.
The resolution was presented by Guilford County Tax Director Ben Chavis.
"As we continue to develop along that boundary, myself and the assessor over there along with our GIS departments are seeing the need to go ahead and get this survey done," he said.
According to state law, surveyors step in to mark the location of uncertain or disputed boundaries when two or more counties don't know the exact line between them.
The vote will allow the North Carolina Geodetic Survey Division to define the line between the two counties so that it's legally recognized.
The Forsyth County Board of Commissioners approved a similar resolution earlier this month.
