Outdoor displays of goods and materials for retail establishments are permitted on private property in front of the retail establishments, provided such displays do not block safe ingress and egress from all entrances and exits including those specifically for emergency use. Such displays shall not block safe pedestrian or vehicular circulation areas, block required parking areas, emergency accessways or interfere with landscape areas such that those areas will be prone to damage, or otherwise create a hazard. In addition, outdoor display of goods and materials shall be properly and safely stored inside during nonbusiness hours. Moreover, outdoor displays shall not encroach in public rights-of-way, including but not limited to streets, alleys or sidewalks, without express written permission of the city council as reflected in an executed temporary license, release and hold harmless agreement. License agreements shall require safe, sturdy and secure outdoor displays and may be subject to an annual fee determined by resolution of the city council.
