An emergency ordinance is an ordinance, which in the judgment of the Council is necessary for the immediate preservation of peace, health or safety, and which should become effective prior to the time an ordinary ordinance would become effective.  Every such ordinance shall contain, as a part of its title the words, “DECLARING AN EMERGENCY” and in a separate section, herein called the emergency section, shall declare the emergency.  The Council shall vote on the emergency section separately, and must adopt the section by a vote of at least five-sevenths (5/7ths) of all members of the Council.
