SWFs that lawfully existed prior to the adoption of the ordinance codified in this article shall be allowed to continue their use as they presently exist. Routine maintenance may be permitted on such lawful preexisting SWFs. Lawfully existing SWFs may be replaced as long as the replacement is in the exact location of the SWF being replaced and is of a construction type identical in height, width, lighting, and painting, or in greater conformance with these standards. Any other changes or modifications to a replacement SWF shall not be considered routine maintenance, shall be treated as new construction, and shall comply with the requirements of this chapter. Such replacement of SWFs shall comply with the requirements of this article, except that as discussed in Subsection III of the FCC’s declaratory ruling, No. 91, the minimum spacing or co-location requirements shall not apply to replacement of an existing SWF installation on an existing pole (Ord. 5067 §1 (Exh. A (part)), 2019).
