"No Smoking" signs or the international "no smoking" symbol (consisting of a pictorial representation of a burning cigarette enclosed in a red circle with a red bar across it) shall be clearly and conspicuously posted in every city park. Notwithstanding this provision, the mere fact that a sign is absent or has been removed once it has been placed as required, shall not, standing alone, be a defense to a charge of having violated the conditions and prohibitions of this chapter. (Ord. 090816-001, 9-8-2016)
