All fixtures associated with an outdoor cafe must be portable and related, as well as limited to food service (e.g., tables, chairs, serving trays). Furnishings of an outdoor cafe shall consist solely of readily removable awnings, covers, canopies, railings, tables, chairs, planters containing plants and accessories. Furnishings may not be attached, even in a temporary manner, to the sidewalk or other public property, except that canopies and railings, if specifically approved by the Planning Commission and the City Council, may be secured by means of flush-mounted anchors or other methods approved by the Building Director. No objects which are part of an outdoor cafe, except lighting fixtures, railings, awnings, or other nonpermanent covers or canopies, may be attached, even in a temporary manner, to any building or structure on which the outdoor cafe abuts.
