9-12-6 LIGHTING

Purpose: It is the intent of this section to encourage lighting practices and systems which preserve the Town’s special resource of dark skies and support the Dark Sky Certification of neighboring Cedar Breaks National Monument by minimizing light pollution, glare, and light trespass, and by eliminating unnecessarily bright light color spectrums. The Town intends to accomplish these objectives without sacrificing night-time safety, mobility, or the ability of businesses to operate reasonably. This section does not apply to indoor lighting. (ord. 18-006, 6-11-2018 amd. ord. 19-014, 1112-2019, amd. ord. 24-014, 10-8-24) A. All light fixtures, including security lighting and sign lighting, except streetlamps, shall be placed at a location, angle and height and shielded so that upward light pollution is minimized: (ord. 19-014, 11-12-2019) 1. Fixtures: Light fixtures shall be mounted to the building or a pole that directs light towards the ground and focuses on the object to be lit. Where signs and similar objects can be lit from above with lighting directed downward, this option should be employed. Where it is not possible, sufficient shielding should be employed to focus the light on the object rather than allowing it to escape upward and pollute the night sky. (amd. ord. 19-014, 11-12-2019) 2. Light fixtures shall be fully shielded on top with opaque material that disallows light from the sources to travel upward into the sky. The sides of the fixture shall be at least partially shielded with either transparent or translucent material. Fixtures which are not fully shielded with opaque material shall be limited to eight hundred (800) lumens per fixture in residential zones and two thousand (2,000) lumens per fixture in all other zones. (amd. ord. 19-014, 11-12-2019) (amd. ord. 24-014, 10-8-24) B. Temperature: The correlated color temperature of any outdoor lighting fixture shall not exceed three thousand degrees kelvin (3,000k). (ord. 19-014, 11-12-2019, amd. ord. 24-014, 10-824) C. Emission: Light fixtures shall not emit more light than is necessary to accomplish its purpose: 1. Lighting fixtures shall be spaced sufficiently to provide adequate light as required by the building code. (ord. 19-014, 11-12-2019) 2. Parking lot lights, yard lights, or both, may be required for multi-family, commercial and industrial projects. The Land Use Authority shall review the proposed lighting plan to determine if meets the minimum lighting requirement necessary for public safety while maintaining sensitivity to night sky preservation. 3. Total outdoor lighting fixtures shall not produce more than one (1) lux at any property boundary for single-family residential purposes or more than twenty-five thousand (25,000) lumens per acre or more than five (5) lux at any property boundary for all other zones. (ord. 19-014, 11-12-2019) 4. Architectural and aesthetic lighting shall use low lumen light sources. (ord. 19-014, 11-122019) (amd. ord. 24-014, 10-8-24) D. Security Lights: Outdoor lighting shall only be used when necessary to accomplish its purpose: (amd. ord. 24-014, 10-8-24) 1. Security lights shall be operated on a motion sensor. Any light on a functioning motion sensor will not count toward the light maximum in subsection C(3) of this title. (ord. 19-014, 11-12-2019) E. Subdivision and Street Lighting: 1. Street lighting will be used to ensure safety and mobility. (amd. ord. 19-014, 11-12-2019). a. Streetlights will be placed at all intersections with a state highway. b. The Public Safety Director may order the placement of additional streetlights where necessary to preserve public safety. c. The specifications of street lighting fixtures will be in accordance with the Town’s Public Works Standards and shall utilize lamp types that are energy efficient, are dark sky compliant, and mitigate the other negative impacts of artificial lighting. d. Pedestrian trails, sidewalks, and walkways may be lit with minimum light necessary to ensure pedestrian safety and in accordance with Public Works Standards. e. Additional streetlights may be used to establish a sense of place in accordance with a Street Lighting Master Plan approved by the Land Use Authority. (ord. 19-014, 11-12-2019, amd. ord. 24-014, 10-8-24). 2. All subdivision plans shall provide for the lighting of all streets in accordance with subsection 9-12-(E)(1) and the Town’s Public Works Standards. (amd. ord. 19-014, 11-122019) a. Additional streetlights along the public right of way may be required by the Land Use Authority in order to better establish a sense of place. Said streetlights, when required, shall conform to the Town’s Public Works Standards. (amd. rd. 19-014, 1112-2019,) b. Subdivision plans shall include: i. The location, height, and overhang of each light. ii. The size of lights in lumens and type of laminator, and the color of the lights (expressed in Kelvin). Where practicable, the most energy efficient laminators shall be used. iii. A drawing or photograph of the typical streetlight and standard proposed and location of energy meter, switches, cutoffs, etc., if any. (amd. ord. 19-014, 11-12-2019, amd. ord. 24-014, 10-8-24) F. Exceptions: The following shall be exempt from the requirements of this chapter: 1. Holiday lighting from November 15 to January 15 as long as it does not create a safety hazard or nuisance to surrounding businesses or residences. 2. Traffic control signals and devices or temporary emergency lighting in use by law enforcement or government agencies or at their direction. 3. The lighting of federal or state flags, provided that the light is a narrow beam aimed and shielded to illuminate only the flag. Flag lighting should use appropriate illumination levels to light the flag, while at the same time fulfilling the purpose of this chapter. Upward lighting of flags is permitted with a limit of three (3) fixtures per flagpole with a maximum of two thousand (2,000) lumens each. The fixtures must be shielded such that the point source is not visible outside of a fifteen-foot (15’) radius. 4. Lights on snow removal or grooming equipment engaged in water snow operations. 5. Lighting for recreational uses (such as ballfields, parks, or night skiing) which do not strictly adhere to the requirements of this section may be approved by the Land Use Authority following a determine that the lighting meets the intent of the requirements of this section and up on the condition that lighting will be subject to a reasonable curfew.
