No ordinance shall be passed or adopted as an emergency measure unless it shall set forth in the body thereof a declaration of the circumstances constituting the emergency. A separate roll call vote shall be had upon such emergency declaration before the final vote upon the passage or adoption of the ordinance and shall be passed if five (5) members of Council affirmatively so vote. If fewer than five (5) members of Council vote affirmatively on the emergency, the ordinance shall then have the same status as any other ordinance.
