In cases where any lot has been sold, the plat or part thereof may be vacated according to either of the following methods:
Roads within the secondary system of highways may be vacated under either of the preceding methods and the action will constitute abandonment of the road, provided the land shown on the plat or part thereof to be vacated has been the subject of a rezoning or special exception application approved following public hearings required by § 15.2-2204 and provided the Commissioner of Highways or his agent is notified in writing prior to the public hearing, and provided further that the vacation is necessary in order to implement a proffered condition accepted by the governing body pursuant to §§ 15.2-2297, 15.2-2298 or 15.2-2303 or to implement a condition of special exception approval. All abandonments of roads within the secondary system of highways sought to be effected according to either of the preceding methods before July 1, 1994, are hereby validated, notwithstanding any defects or deficiencies in the proceeding; however, property rights which have vested subsequent to the attempted vacation are not impaired by such validation. The manner of reversion shall not be affected by this section.
