The Council may, by a two-thirds (2/3) vote of the members elected thereto, pass emergency measures to take effect at the time indicated therein. Any measure necessary for the immediate preservation of the public peace, property, health or safety, or providing for the usual daily operation of a municipal department, in which the emergency is set forth and defined in a preamble thereto, may be an emergency.
Ordinances appropriating money may be passed as emergency measures, but no measure making a grant, renewal, extension or amendment of a franchise or other special privilege, or regulating the rate to be charged for its service by any public utility, shall ever be so passed.
