The purpose of this chapter is to encourage the quantity and level of lighting necessary for safety, security and the enjoyment of outdoor living while protecting and preserving the beauty of the night sky. The type of lighting and the location of lighting fixtures are key components of effective lighting. It is the intent of this chapter to effectively light areas with lighting fixtures that limit glare and direct light onto the area to be lit.

The purpose of this chapter is to assist in implementing the Ivins City General Plan that includes the following Vision Statement:

Effective outdoor lighting enhances the City's character and identity, promotes a pleasant and soft ambiance, protects astronomical observations, and provides safety and security for persons and property.

Outdoor lighting has a number of functions, it must promise immediate good vision and orientation so that an area is usable and safe at night. By means of placement and intensity, lighting is also used to guide pedestrian and vehicular movement and highlight areas where traffic conflicts. Lighting is also used for architectural emphasis and effect, to attract business, and to give a site a particular "personality". All area lighting has the ultimate purpose of providing visibility. Good visibility is achieved through the interaction of intensity, direction, and reflection of light so that an observer can immediately translate received light into terms of shapes, surfaces, distance and movement.

In order to effectively regulate these activities, communities are empowered to establish regulations and standards for all outdoor lighting. This chapter contains standards and guidelines to maintain appropriate levels of lighting for safety and security while preserving, protecting, and enhancing the "night sky" in Ivins City.

This chapter, and any rules, regulations and specifications hereafter adopted, is initiated for the following purposes:

   (1)   To promote and protect the public health, safety and welfare.

   (2)   To preserve, protect, and enhance the natural beauty of the "night sky".

   (3)   To encourage and promote the conservation of energy resources.

   (4)   To maintain and enhance property values.

   (5)   To adopt clear standards for all outdoor lighting and to inform the public of those standards.

   (6)   To implement the goals and objectives of the Ivins City General Plan.

   (7)   To implement the goals and objectives of the Ivins City Design Guidelines and Standard Specifications for Design and Construction.

   (8)   To eliminate light trespass onto abutting properties.

   (9)   To promote appropriate business.

   (10)   To allow flexibility for creative lighting.

   (11)   To avoid duplicate lighting sources.

   (12)   To enhance community image.

   (13)   To comply with adopted state energy codes.

Listed herein are standards and criteria for lighting. It is important to note that the intent of this section is to effectively regulate lighting, and it is not the intent of this section to limit creative lighting solutions. Creative approaches to lighting are encouraged and viable alternatives to these standards and guidelines may be substituted if the alternatives can be demonstrated to meet the intent of this chapter and do not otherwise violate this chapter.

   (1)   Type of Lights Recommended: LED Lamps and other lighting technologies, current or future, that have similar or better energy efficiencies.

   (2)   Conformance with Applicable Codes. All outdoor electrically powered illuminating devices shall be installed in conformance with the provisions of this chapter, Building Codes, the Electrical Code, and Sign Ordinance, with appropriate permits and inspection. Reference applicable IES publications.

   (3)   Color/Temperature: Warm lighting colors are required and blue-white colors are generally prohibited. In this regard, all outdoor light shall meet the following:

      (a)   For non-residential properties, private streets and parking lot lighting: The correlated color temperature (CCT) of outdoor lamps shall be three thousand degrees Kelvin (3,000°K) or less.

      (b)   For residential properties, the correlated color temperature (CCT) of all outdoor lamps shall be three thousand degrees Kelvin (3,000°K) or less.

   (4)   Light Trespass. All light fixtures, including security lighting, shall be aimed and shielded so that the direct illumination shall be confined to the property boundaries of the light source. Direct illumination shall not fall onto or across any public or private street or road. No spill lighting is permitted.

   (5)   Fully Shielded Fixtures. All outdoor lighting shall be full cut-off fixtures fully shielded with fixtures installed and aimed in such a way so that no direct light is emitted above the horizontal or trespassing into adjacent properties including the adjacent street. Shielding may be accomplished by: full cut-off fixtures; design; shielding; visors; louvers; or other devices. See examples of shielding in Figures 23-2 and 23-3.

   (6)   Spotlights. Spotlights shall be shielded, aimed or directed toward the ground and no light shall trespass into a neighboring property or create direct glare for motorists.

   (7)   Searchlights, Floodlights, etc. Searchlights, floodlights, laser source lights, strobe, or flashing lights, illusion lights, or any similar high intensity light shall not be permitted except in emergencies by public safety personnel or at their direction.

   (8)   Site Shielding. In certain cases, additional shielding may be required to mitigate glare or light trespass. The need for additional shielding shall be considered as part of the development review process described in the Ivins City Subdivision Ordinance.

   (9)   Up-lighting. Up-lighting (light pollution) is prohibited unless the light is shielded in a manner that confines the light to the surface of a building façade or other object of illumination, without spill light.

   (10)   Light Curfews.

      (a)   Pathway Lighting. The intent of pathway lights is to provide pools of light to help direct pedestrians along the path, not to fully illuminate the path. Steps and path intersections should be illuminated for safety. The maximum average foot-candle permitted on the ground is an average one (1) horizontal foot-candle or less. Two (2) types of lights may be selected: three and one half (3'6") foot bollards with louvers or ten (10) foot pole mounted down directed luminaires. Lights must be shielded.

   (15)   Trails. Trails lighting shall be low-level bollards (below eye level where possible), shielded, and designed to meet all requirements established in this chapter and in accordance with the Standard Specifications for Design and Construction. Bollards shall not be necessary where trail is within one hundred feet (100') of a streetlight. Other low-level lighting alternatives shall be considered during the development process on a case by case basis.

The provisions of this chapter shall only apply prospectively from the date they were adopted and not retroactively. Outdoor lighting that conformed with Ivins City ordinances prior to the adoption of a provision of this chapter shall be treated similarly to a legal nonconforming use that can be maintained or replaced but not expanded. Where applicable, the Ivins City Zoning Administrator is authorized as the enforcing officer for this chapter, and shall enforce all applicable provisions, entering actions in court if necessary, and his failure to do so shall not legalize any violations of this chapter.
