“Shopping arcade” means a continuous covered area open to the public at all times, having direct access from all the streets or plazas which it adjoins or connects, devoted to consumer shopping uses such as, but not limited to, flower and gift shops, indoor-outdoor cafes, art galleries and similar specialty shops readily accessible to the public from it. To help ensure that required consumer shopping uses are retained and the public interest served, in the event such spaces cease to function for their intended purpose, the actual area so affected or an equivalent area shall be converted into readily accessible public space either as additional plazas, arcades or public display areas. (Ord. 871 §2 (part), 1989).
