Commercial developments adjacent to property zoned and/or used for residential purposes shall install a six (6) foot privacy fence between commercial and residential properties to afford privacy for the residential dwellings. The fence shall be installed so as not to create a safety hazard for vehicular and pedestrian traffic. Where the Planning Commission determines that such a fence is not necessary or in the best interest of the public, the Planning Commission may waive the fence requirement. (PZSC § 03-25-003 (3))
