The Township staff shall also advertise the proposed amendment as required by the Municipalities Planning Code and, if the proposal involves any change to the Zoning Map, any affected property shall be posted. The Board of Supervisors shall hold such public hearing or hearings as it deems appropriate on the proposal submitted by the landowner to amend the Zoning Ordinance and/or Zoning Map, but the Board shall be under no obligation to take any final action on the proposal.
