The provisions of this Chapter and all other ordinances which establish time limit spaces or zones on any street, parking lot or other parking facilities regulated by the City notwithstanding, the City Council may, by resolution, increase or decrease the hours or days of enforcement. In the event the City Council establishes hours of enforcement other than between 9:00 a.m. and 6:00 p.m. daily except Sundays and holidays, appropriate notice shall be given to advise of said special hours and days of enforcement. Actions taken by the City Council to increase or decrease hours or days of enforcement prior to the adoption of this Section remain in full force and effect.
