§ 7. Emergency measures; effective date.

An emergency measure is one which is necessary for the immediate preservation of the peace, health or safety of the city and one which is passed by the affirmative vote of 3/4ths of the members of the council and which receives the approval of the mayor. An emergency measure shall take effect immediately upon the passage, so long as it states in a separate section, the reason why it is necessary that it should become immediately operative. An emergency measure may be added to an ordinance upon its second reading and final passage at the same meeting as when first introduced upon the affirmative vote of 3/4ths of the council and upon its receiving the approval of the mayor.
