The Council may, by ordinance approved by four-fifths vote, vacate any street, alley, public grounds, public way or any part thereof within the City.
Such vacation may be made only after published notice and an opportunity has been given to affected property owners and the public to be heard, and upon such further terms and by such procedure as the Council, by ordinance, may prescribe.
In a proceeding under this Section, an easement may be reserved for any purpose, which the Council deems appropriate.
