15.42.150: MODIFICATIONS:
   A.   Permit: A new permit must be obtained prior to any proposed change or addition to any WCF, provided that routine maintenance or replacement of any portion of the WCF with identical equipment in conformance with this chapter shall not require application for a new permit.
   B.   Existing Uses: All WCFs existing on the date of passage of the ordinance codified herein shall be allowed to continue their operation as they presently exist, subject to the terms of this chapter relating to abandonment or discontinuance of use. Routine maintenance shall be permitted, but construction involving the replacement of support structure apparatus, antennas, or any exterior alteration must be done in compliance with the terms of this chapter.
   C.   Exception: Emergency service WCFs may obtain a waiver from the city council if required for preserving the public health and safety. Issuance of the waiver shall require a public hearing and a finding on the part of the council that the modifications cannot comply without undue burden on the citizens of the city.
