If you and a neighbor wish to adjust the boundary lines between parcels, you must have approval of the Board of County Commissioners through an official Boundary Line Adjustment process. If none of the properties involved in the adjustment (before or after adjustment) is under 35 acres in size, this process is not necessary.
