The Legislature by statute shall provide for the incorporation, organization, and dissolution of cities and towns and for their classification in proportion to population. Any incorporated city or town may frame and adopt a charter for its own government in the following manner:
Amendments to any such charter may be framed and submitted by a charter commission in the same manner as provided for making of charters, or may be proposed by the legislative authority of the city upon a two-thirds vote thereof, or by petition of qualified electors to a number equal to fifteen per cent of the total votes cast for mayor on the next preceding election, and any such amendment may be submitted at the next regular municipal election, and having been approved by the majority of the electors voting thereon, shall become part of the charter at the time fixed in such amendment and shall be certified and filed as provided in case of charters.
Each city forming its charter under this section shall have, and is hereby granted, the authority to exercise all powers relating to municipal affairs, and to adopt and enforce within its limits, local police, sanitary and similar regulations not in conflict with the general law, and no enumeration of powers in this constitution or any law shall be deemed to limit or restrict the general grant of authority hereby conferred; but this grant of authority shall not include the power to regulate public utilities, not municipally owned, if any such regulation of public utilities is provided for by general law, nor be deemed to limit or restrict the power of the Legislature in matters relating to State affairs, to enact general laws applicable alike to all cities of the State.
The power to be conferred upon the cities by this section shall include the following:
(b) To furnish all local public services, to purchase, hire, construct, own, maintain and operate, or lease, public utilities local in extent and use; to acquire by condemnation, or otherwise, within or without the corporate limits, property necessary for any such purposes, subject to restrictions imposed by general law for the protection of other communities; and to grant local public utility franchises and within its powers regulate the exercise thereof.
(c) To make local public improvements and to acquire by condemnation, or otherwise, property within its corporate limits necessary for such improvements; and also to acquire an excess over than [that] needed for any such improvement and to sell or lease such excess property with restrictions, in order to protect and preserve the improvement.
(d) To issue and sell bonds on the security of any such excess property, or of any public utility owned by the city, or of the revenues thereof, or both, including, in the case of public utility, a franchise stating the terms upon which, in case of foreclosure, the purchaser may operate such utility.
