Subject to the provisions set forth herein, all parking areas, walkways, driveways, building entryways, off-street parking and loading areas, and building complexes with common areas shall be sufficiently illuminated to assure the security of property and the safety of persons using such public or common areas. All lighting must comply with Chapter 92, § 92.03(B) of the City Code of Ordinances.
(A) Permitted lighting. Only non-glare, color-corrected lighting shall be permitted. Lighting shall be placed and shielded so as to direct the light onto the site and away from adjoining properties. The lighting source shall not be directly visible from adjoining properties. Lighting shall be shielded so that it does not cause glare for motorists (see Appendix B, Illustration 10, Lighting Requirements).
(B) Intensity. In parking areas, the light intensity shall average a minimum of 1.0 footcandle, measured five feet above the surface. In pedestrian areas, the light intensity shall average a minimum of 2.0 footcandles, measured five feet above the surface.
(C) Height. Except as noted below, lighting fixtures shall not exceed a height of 25 feet measured from the ground level to the centerline of the light source. Fixtures should provide an overlapping pattern of light at a height of approximately seven feet above ground level. The Planning Commission may modify these height standards in commercial and industrial districts, based on consideration of the position and height of buildings, other structures, and trees on the site; the potential off-site impact of the lighting; the character of the proposed use; and the character of surrounding land use. In no case shall the lighting exceed the maximum building height in the district in which it is located.
(E) Site plan requirements. All lighting, including ornamental lighting, shall be shown on site plans in sufficient detail to allow determination of the effects of the lighting upon adjacent properties, traffic safety, and overhead sky glow. The objective of these specifications is to minimize undesirable off-site effects.
(F) Lighting around architectural building features. Lighting around architectural building features is subject to the following requirements:
(1) Static light only. Only static light is permitted around architectural building features, and any flashing, fading, dissolving, or any other change in color or illumination level is prohibited.
(2) Maintenance of bulbs. All bulbs around architectural building features must be functional. Bulbs that are nonfunctional or dysfunctional must be replaced with a bulb of the same color as, or sequence of color of, the other bulbs to maintain uniformity.
(3) Standards applicable to architectural outline lighting. Tube lighting around architectural features on any existing or proposed building may be approved administratively through the zoning permit process of § 154.467, provided the tube lighting does not cause glare and is not hazardous to traffic safety. In considering whether to approve the architectural lighting, the city shall consider the light's impact on traffic, neighboring properties, and the night sky in accordance with the requirements of this section. The city may require the lighting to be shielded or diffused by translucent panels, tubes, or similar methods. String lights, rope lighting, and other similar lighting with exposed or visible bulbs are prohibited on architectural features.
(H) Temporary lighting. Temporary string lights and other lighting around windows and architectural building features are permitted not more than 90 days in a calendar year (e.g., holiday lighting, etc.). These forms of temporary lighting are subject to all illumination standards of this section.
