Except insofar as limited by State law and the provisions of this Charter, the Council shall have the power to establish, vacate and use, and to patrol and regulate the use of, its streets, alleys, bridges and public grounds whether such public places be located within or without the limits of the City, and space above and beneath them. Such power shall include, but not be limited to, the proper policing and supervision thereof; the licensing and regulation, the prohibition of the placing of signs, awnings, awning posts and other things which are of such nature as to impede or make dangerous the use of sidewalks or streets of the City; and the licensing and regulation of the construction and use of openings of sidewalks and streets and of all vaults, structures and excavations under the same.
Provided that when the Council shall deem it advisable to vacate, discontinue or abolish any highway, street, lane, alley or public ground or any part thereof, it shall appoint a time, not less than four weeks thereafter, and hear objections thereto; notice of such meetings, with a copy of said resolution, shall be given in such manner as shall be prescribed by ordinance or resolution. Objections to such proposed action of the Council may be filed with the Clerk in writing, and if such shall be filed, the street, alley or public ground or any part thereof shall not be vacated or discontinued except by vote of four of the members of the Council.
