A. All outdoor lighting fixtures shall be installed in conformance with the provisions of this Article and any other building code requirements, as applicable.
B. Where any provisions of any of the Arizona Revised Statutes, any federal law, or any companion ordinance conflict with the requirements of this Outdoor Light Control Article, the most restrictive provision shall govern.
C. All new development and those portions of any addition to an existing commercial, industrial, or multi-family development requiring a commercial site plan review and requiring outdoor lighting shall meet the requirements of this Article.
D. All outdoor light fixtures, existing and fully installed, or for which a building permit has been issued prior to the effective date of this Article, shall be considered legal non- conforming (see Article 151.24). No modification or replacement shall be made to a nonconforming fixture unless the fixture thereafter conforms to the provisions of this Article, except that lamp and related apparatus (lens, ballast, etc.) replacement is allowed. Abandoned site lighting fixtures shall be regulated according to the provisions of Article 151.24.
E. Legal, non-conforming lighting fixtures may continue to be used provided such fixtures are turned off between the hours of 10:00 p.m. (or when the business activities cease, whichever is later) and sunrise. This requirement does not apply to fixtures used for safety or security purposes. Non-conforming lights that are improperly aimed and, as a result, are considered a detriment to public health, safety, and welfare shall be regulated under the City’s public nuisances and property maintenance codes.
F. A reduction of non-conforming lighting fixtures is required on an existing developed commercial site where a site plan or modified site plan review is required for new development. This reduction shall be as determined by the City. Possible means for this reduction are as follows:
1. Appropriate fixture aiming to reduce light trespass;
2. Tilting any existing fixtures to a horizontal position to maximize available shielding;
3. Adding shielding to fixtures when possible;
4. Utilizing motion sensors or automatic shutoff devices to eliminate unnecessary use of energy resources.
5. Conforming lighting fixtures shall be turned off between the hours of 10:00 p.m. (or when the business activities cease, whichever is later) and sunrise. This requirement does not apply to fixtures used for safety or security purposes. (Sign lighting cannot be used for security lighting purposes.)
