ATTEST: Theresa White City Clerk Pamela B. Kennedy Mayor EXHIBIT A Section 27.22.104 -OUTDOOR LIGHTING PURPOSE AND INTENT: Light pollution obscures the night sky, a resource important to residents and visitors. -Light trespass interferes with the quality of life and public safety of the community. Standards for outdoor lighting are intended to control artificial light from non -vehicular sources that produce glare light trespass, nuisance light and / or degrade the night sky. These standards are intended to reduce and eliminate nuisance glare and light trespass from poorly placed, inappropriate, misaligned or improperly shielded light sources. It is the further intent of these standards to conserve energy and resources as well as to curtail and reverse the degradation of the night sky through the regulation of the type and use of outdoor lighting while maintaining night-time safety, utility and security. APPLICABILITY: All residential and commercial lighting whether on public or private property installed in the city limits of Kalispell shall comply with the requirements and specifications established with these regulations. STANDARDS: 1. All lights shall be shielded and directed in such a way as to direct all light toward the intended area and away from reflective surfaces. 2. Lighting shall be designed, directed and shielded in such a manner that direct light does not leave the perimeter of the site as limited by these regulations. 3. All outdoor lighting, including the fixture, pole, and other supporting elements, shall be designed to complement the overall architectural appearance of the site and prevent excessive glare. 4. The height and level of lighting should be appropriate for the development. Lights mounted on poles shall not be taller than the building area they illuminate or taller than 30 feet, whichever is less. 5. Roof illumination is not allowed. 6. When practical, timing mechanisms and photo cells shall be used to reduce light levels and conserve energy during non -operational hours. 7. Lighting mounted on the building should be integrated as an architectural component. It shall be designed so the light is fully shielded and directed toward the building. S. Canopy lighting, such as service station lighting, shall be fully recessed and shielded to ensure that no light source is visible from or causes glare in the public right of way or adjacent properties. Any canopy structure used at a business location must have recessed lights with diffusers which do not extend below the surface of the canopy. 9. Low voltage landscape lighting will be allowed provided it is directed toward the object or building and does not leave the perimeter of the site or contribute to light trespass. 10.All pole mounted lighting shall have a full cut --off fixture that does not allow light to shine above a 70 degree angle measured from a vertical line from the center of the lamp. 11. Mercury vapor lights are prohibited because of the poor color spectrum, light intensity and inefficient energy use. 12. Low pressure or high pressure sodium lights and metal halide are encourages rather than the use of florescent lights. 13. Light fixtures or lamps shall be shielded or shaded in such a manner so that the light emitting surface is not visible and to direct incident rays away from all adjacent property. 14.Any light fixture must be placed in such a manner so that no light emitting surface is visible from any residential area or public/private roadway, walkway, trail or other public way when viewed at ground level. 15. The level of lighting shall not exceed 0.3 foot candles at any residential property line or 0.5 foot candles at any non-residential property line. 16. Floodlights shall have external shielding or shall be directed and angled so that no light is visible above a 70 degree angle measure from a vertical line from the center of the lamp and shall not shine onto any adjacent public right of way or adjacent property. 17. Any interior lighted signs may not be lit at night when any face of the sign is removed or damaged in such a way that the light may distract or intrude on drivers or adjacent properties. 18. Signs that have exterior lighting must be lit from above the sign and the light shielded except that ground lighting may be used for ground mounted signs with a solid base. In all cases lighting must be directed at the surface of the sign area. SPECIFIC USES: Security Lighting for Commercial and Residential Uses. Security lighting is defined as lighting designed and used to discourage crime and undesirable activity which includes parking lot lighting. 1. Security lighting should use the lowest possible illumination to effectively allow surveillance. 2. The use of sensor technologies, timers or other means to activate lighting during times when it will be needed may be required by the zoning administrator to conserve energy, provide safety, and promote compatibility between different land uses. 3. Both commercial and residential security lighting shall be shielded so the light source is not visible and the light is aimed _so that illumination is directed to the designated areas. All non --essential exterior commercial lighting is to be turned off after business hours. Architectural Accent Lighting: 1. Fixtures used to accent architectural features, materials, colors, style of buildings, landscaping, or art shall be located, aimed and shielded so that light is directed only on those features. Such fixtures shall be aimed or shielded to minimize light spill into the dark night sky in conformance with the lurninaire standards. 2. Lighting fixtures shall not generate excessive light levels, cause glare, or direct light beyond the facade onto neighboring property, streets or the night sky. Canopy Lighting and Lighting of Service Stations: In addition to the general standards previously listed, the following also apply: Lighting of such areas shall not be used to attract attention to the business. Lighting levels shall be adequate to facilitate the activities taking place in such locations. In order to minimize the extent of direct glare, light fixtures mounted on canopies shall be recessed so that the lens cover is recessed or flush with the bottom surface (ceiling) of the canopy or shielded by the fixture or the edge of the canopy so that light is restrained to 85 degrees or less from vertical. 2. As an alternative (or supplement) to recessed ceiling lights, indirect lighting may be used where light is beamed upward and then reflected down from the underside of the canopy. When this method is used, light fixtures must be shielded so that direct illumination is focused exclusively on the underside of the canopy. 3. Lights shall not be mounted on the top or sides (fascias) of the canopy. Uutdooi Sports of LCeC euL1Vll r 1C1L1S5 of _rcl lul llic_Uluv f11 eas. 1. Lighting of outdoor recreational facilities (public or private), such as, but not limited to, football fields, soccer fields, baseball fields, softball fields, tennis courts, special event or show areas, shall use fixtures with a full --cutoff lens. 2. Lights are to be used only when the field is in use. Flags of the United States or Montana may be illuminated from below provided such lighting is focused primarily on the individual flag or flags to limit light trespass and spill into the dark might sky. Flags are encouraged to be taken down at sunset to avoid the need for lighting. Searchlights. The operation of searchlights for any purpose other than an emergency need is prohibited. Towers. Lighting on towers is prohibited except as required by regulations of the Federal Aviation Administration. PROCEDURE: At the time of site plan approval by the Kalispell Site Development Review Committee, the applicant must supply a lighting plan in accordance with these regulations and shall demonstrate conformance with these standards. At a minimum the lighting plan shall include: Manufacturer specifications regarding the light fixture, proposed locations, mounting heights and direction of all exterior lighting. 2. If the building, signage or landscaping is proposed to be lit, relevant drawings shall be provided showing the type, location and direction of the light fixture. 3. If needed, additional information may be required by the site development review committee in order to demonstrate compliance with these regulations which may include photometric data of all lighting and other descriptive information on the fixtures and / or a computer generated photometric grid showing foot candle reading every 10 feet within the property or site and ten feet beyond the property boundaries. NON -CONFORMING LIGHTING Lighting for commercial uses including but not limited to parking lot and building lighting that does not conform to these regulations shall be brought into compliance within three five years of the effective date of the adoption of these regulations or by September 1, 2010 or when the light fixtures are removed or replaced whichever occurs first. Two one year extensions may be considered by the Kalispell City Council based upon a specific hardship and upon written request. Residential lighting that does not conform to these regulations shall be brought into compliance within one year of the adoption of these regulations or by September 1, 2006 or when the light fixtures are removed or replaced whichever occurs first. DEFINITIONS, FIGURES AND TABLES: The attached definitions figures and tables are incorporated as guidelines for public information and enforcing this section. DEFINITIONS 1. Canopy structure: Any overhead protective structure which is constructed in such a manner as to allow pedestrians/vehicles to pass under. 2. Fixture: The assembly that holds a lamp and may include an assembly housing, a mounting bracket or pole socket, a lamp holder, a ballast, a reflector or mirror, and a refractor or lens 3. Foot candle: A unit of illumination produced on a surface, all points of which are one foot from a uniform point source of one candle. Originally the measure of the amount of light emitted by a candle onto one square foot of surface one foot away, foot candles are now the standard unit of measuring light. A .foot candle is equal to one lumen per square feet. 4. Full cut off fixture: A fixture, as installed, that are designed or shielded in a such a manner that all light rays emitted by the fixture, either directly from the lamps or indirectly from the fixture, ar projected below a horizontal plane ru nning throught the lowest point on the fixture where light is emitted. 5. Glare: Direct light emitted by a luminaire that causes reduced vision or momentary blindness. 6. Illuminance: The level of light measured at a surface. 7. Lamp: The component of a luminaire that produces the light. 8. Light direct: Light emitted directly by a lamp, off a reflector, or through a refractor of a luminaires 9. Light emitting surface: Any part of a fixture (lamp, diffusor) which emits light rays. 10. Light pollution: General sky glow caused by the scattering of artificial light in the atmosphere, much of which is caused by poorly -designed luminaries. 11. Light shield: Any attachment which interrupts and blocks the path of light emitted from a luminaire or fixture. 12. Light trespass: Light emitted by a luminaire that shines beyond the boundaries of the property on which the luminaire is located. 13. Lumen: A unit of measurement of luminous flux. 14. Luminaire: The complete lighting system, including the lamp and the fixture. 15. Luminaire full cutoff: A luminaire that allows no direct light emissions above a horizontal plane through the luminaire's lowest light -emitting part. 16. Luminaire permanent outdoor: Any fixed luminaire or system of luminaries that is outdoors and this is intended to be used for seven (7) days or longer. 17. Lux The international standard unit for measuring light levels (as oppose to Foot - Candle in the U.S.A). It is one lumen per square meter. (See Lumens and Foot - Candle). 18. Wattage: the amount of electrical power consumed by a lamp or light fixture measured in "watts". One watt is equal to the power dissipated by 1 ampere of electrical current flowing across a resistance of I ohm or the power produced by I ampere of electrical current under an electromotive force of 1 volt. One horsepower is equal to 746 watts. Formulae: watts = volts x amps, P = V x I, electrical power electromotive force x electric current.
