A. Whenever any two localities have agreed that a change should be made to their common boundary line so that public services in an area may be provided more effectively and more efficiently, but are unable to agree as to the proper location for the new boundary line, their governing bodies may petition jointly either of the circuit courts for their respective localities for an order establishing the new boundary line within the terms of the petition. The court shall refer the petition to the Commission on Local Government, and shall also certify the filing of the petition to the Supreme Court with a request that a three-judge court be convened pursuant to § 15.2-3000 to decide the matter. The Commission shall conduct a hearing to receive evidence concerning the location of the new boundary line. Any interested persons may present evidence. The Commission shall publish notice of its hearing at least once a week for two successive weeks in newspapers of general circulation in each locality. Based upon the evidence and the report of its staff, the Commission shall determine a new boundary line that best promotes the more effective and efficient provision of public services. The Commission shall transmit its findings to the court in writing, where they shall be received in evidence. The court shall hear evidence with respect to relocating the boundary line and shall enter an order establishing the new boundary line so as to promote, to the extent possible, the more effective and more efficient provision of public services. Such order shall set forth the terms for the transfer of territory and shall be recorded in the common-law order book and in the current deed book for both localities’ courts and indexed in the name of the localities as the case may be. A certified copy of the order shall be sent to the Secretary of the Commonwealth by the clerk of the circuit court.
