Full Breakdown
520(A) defines 'public place' broadly as any place in a non-residential zoning district to which the general public has access for business, entertainment or other lawful purpose, plus the front or immediate area of stores, shops, restaurants and taverns, and public grounds, areas or parks. Subsection (B) makes it a violation to possess an opened container of beer, wine or intoxicating liquor while in such a public place. 520(D) exempts possession on any portion of a public park other than its parking areas, on grounds where a permitted public festival, concert, sporting event or performing arts event is underway, and on the premises of a convention facility or reception hall.
This structure lets O'Fallon permit alcohol at City-sanctioned festivals and in most park areas while still barring open containers on ordinary streets, sidewalks and parking lots. The ordinance dates to Ordinance No. O. 520.
