(a) To meet a public emergency, the Council may adopt ordinances effective on adoption. Every emergency ordinance must contain a statement by the Council of why an emergency exists and a statement of the facts about the emergency. The ordinance may be adopted, amended and adopted, or rejected at the meeting at which it is introduced. The affirmative vote of all members present, or the affirmative vote of three-fourths of the total membership, whichever is less, is required for adoption. The Council must print and make available copies of adopted emergency ordinances.
(b) An emergency ordinance may not be used to levy taxes, to grant, renew or extend a franchise, or to regulate the rate charged by a public utility for its services.
(c) Emergency ordinances are effective for 60 days.
