Except as otherwise specially provided, whenever the governing body of any municipality shall deem it necessary to appropriate or damage any private property, either within or without the corporate limits of the municipality, for any purpose authorized by law, it shall, by a resolution passed by a two-thirds majority of all the members elected thereto, declare such appropriation necessary, stating the purpose and extent of such appropriation. Thereupon the proceedings for such appropriation and condemnation shall be as provided by law and the rules of practice and procedure adopted by the Supreme Court.
