The Downtown Core (DT2) zone shall generally be located in the historic center of Provo and shall be surrounded completely by the less intensive General Downtown (DT1) zone. The DT2 zone shall not directly abut any R1 or RC zone and shall only expand to the degree that the DT1 zone, or any other appropriate commercial zone, may appropriately act as a buffer between the DT2 zone and any R1or RC zone. The DT2 zone shall have no minimum area requirement.
