The Council may, by a two-thirds vote of the members elected thereto, pass emergency measures to take effect at the time indicated therein. An emergency measure is an ordinance or resolution 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. Ordinances appropriating money may be passed as emergency measures, but no measure making a grant, renewal or extension of a franchise or other special privilege, or regulating the rate to be charged for its services by any public utility, and no measure levying a tax on or measured by income, payroll, earnings or profits, shall ever be so passed.
