The following are permanent exemptions to the provisions of this chapter.
A. Nonconforming Fixtures. All outdoor fixtures existing and fully installed prior to the effective date of the ordinance codified in this chapter may remain “nonconforming” indefinitely; provided, however, that no change in use, replacement, structural alteration, or restoration after abandonment of outdoor light fixtures shall be made unless it thereafter conforms to the provisions of these regulations.
B. Fossil Fuel Light. Fossil fuel light produces directly or indirectly by the combustion of natural gas or other utility-type fossil fuels.
C. Federal and State Facilities. Those facilities and lands owned, operated or protected by the U.S. Federal Government or the state of Arizona are exempted by law from all requirements of this chapter. Voluntary compliance with the intent of this chapter at those facilities is encouraged.
D. Special Exemption. The zoning inspector may grant a special exemption to the requirements of Section 15.48.070 only upon a written finding that there are extreme geographic or geometric conditions warranting the exemption and that there are no conforming fixtures that would suffice.
