The regulations, restrictions and boundaries established within this ordinance may, from time to time, be amended, supplemented, changed, modified, or repealed by a majority of votes of the governing body provided:

16-1-1. The planning commission shall hold at least one public hearing on such proposed amendment after notice as required by Code of Virginia, § 15.2-2204, and may make appropriate changes in the proposed amendment as a result of such hearing. Upon the completion of its work, the commission shall present the proposed amendment to the governing body together with its recommendations and appropriate explanatory materials.

16-1-2. Before approving and adopting any amendment, the governing body shall hold at least one public hearing thereon, pursuant to the public notice as required by Code of Virginia, § 15.2-2204 after which the governing body may make appropriate changes or corrections in the proposed amendment; provided, however, that no additional land may be zoned to a different classification than was contained in the public notice without an additional public hearing after notice required by Code of Virginia, § 15.2-2204. An affirmative vote of at least a majority of the members of the governing body shall be required to amend the zoning ordinance.

16-1-3. Amendments may be initiated by resolution of the governing body, by motion of the planning commission, or by petition of any property owner or his agent addressed to the governing body.

16-1-4. The governing body and the planning commission shall refuse to hold further hearings on a renewed application for the same amendment or zoning permit by the same applicant, or applicants, their successors or assigns for a period of 12 months after the commission's action thereof, except and unless the planning commission or governing body shall find and determine from the information supplied by a request for a rehearing that is unusual, changed conditions have occurred relating to the promotion of the public health, safety, convenience, comfort, property and general welfare and that a reconsideration is justified. If the rehearing is denied, the case shall not be reopened for at least 12 months from the date of the original action by the planning commission.

16-1-5. Changes shall be made by the governing body in the zoning ordinance or the zoning map only after such changes have been referred to the commission for a report. Action shall be taken by the governing body only after a report has been received from the commission, unless a period of 90 days has elapsed after the first meeting of the commission after the proposed amendment or reenactment has been referred to the commission after which time it may be assumed the commission has approved the changes or amendments.
