For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning. Terms that are not defined below, but are defined elsewhere in the Code of Ordinances, shall be given the meanings set forth therein. Words or phrases not defined in the Code of Ordinances shall be given their common, ordinary meaning unless the context clearly requires otherwise.
BARN-LIGHT. Commonly referred to as a dusk-to-dawn light and is generally unshielded and used in rural applications.
BULB OR LAMP. A light-emitting device or a structure containing a light source that includes but is not limited to a lamp.
COLOR RENDERING INDEX (CRI). A quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with a natural or standard light source.
DARK SKY. A place where darkness of the night sky is reasonably free of interference from artificial light.
FIXTURE. The complete assembly that holds the lamp, including any elements designed to provide light output control such as a reflector or refractor, the ballast and housing.
FOOTCANDLE (FC). A unit of light intensity equal to one lumen per square foot, which applies to the brightness of light on a surface or at a point in space.
FULLY SHIELDED LIGHT FIXTURE. A light fixture constructed and installed in such a manner that all light emitted by the fixture, either directly from the luminaries or a diffusing element, or indirectly by reflection or refraction from any part of the fixture, are not permitted to project above the horizontal plane through the fixture’s lowest light-emitting part or beyond the area intended to be illuminated.
GLARE. Lighting entering the eye directly from luminaires or indirectly from reflective surfaces that causes visual discomfort or reduced visibility.
HOLIDAY LIGHTING. Temporary lighting for a specific celebration that consists only of traditional festoon-type low-output lamps. Spotlights and searchlights are prohibited.
ILLUMINATION/ILLUMINANCE. The density of lumens incident on a surface expressed in footcandles.
KELVIN, KELVIN COLOR TEMPERATURE SCALE. The Kelvin color temperature scale is used to describe the way various light temperatures appear visually. It is measured in degrees on a Kelvin scale (K) and typically ranges from 2,700 degrees Kelvin (yellow/warm light) to 5,000 degrees Kelvin (blue/cool light).
LIGHT/LIGHTING. Any source of light that does not include natural light emitted from celestial objects or fire. The term includes, without limitation, any type of lighting, fixed or movable, designed or used for outdoor illumination of buildings or homes, including lighting for billboards, streetlights, canopies, gasoline station islands, searchlights used for advertising purposes, externally or internally lit advertising signs, and luminous elements or lighting attached to structures, poles, the earth, or any other location.
LIGHT TRESPASS. Light that falls beyond the property it is intended to illuminate; for example, onto a motor vehicle, upwards toward the sky, or onto another property, and the like.
LUMEN. A measure of the amount of light emitted by a lamp; the higher the number of lumens, the brighter the lamp. The initial lumen rating associated with a given lamp is generally indicated on its packaging or may be obtained from the manufacturer.
LUMINAIRE, OR LUMINOUS ELEMENTS (OF A LIGHT FIXTURE). Individually or collectively the lamp (light bulb), any diffusing elements and surfaces intended to reflect or refract light emitted from the lamp.
NET ACRE. The unit of land area which comprises an acre, less that portion of land covered by any building.
NON-RESIDENTIAL PROPERTY. Non-residential property includes the following:
(1) Property that is not located in the following residential zoning districts: (SF-15) Single-Family Residential District, (SF-22) Single-Family Residential District, (SF-43) Single-Family Residential District, (SFE-3.0) Single-Family Estate 3.0 Residential District, (PD) Residential Planned Development, (D) Duplex Residential District, (TH) Townhouse Residential District;
(2) Property such as parks, common areas, amenity centers, trails, streets, and entry features associated with neighborhoods and subdivisions regardless of zoning district;
(3) Non-residential uses situated in the take-area of Lake Ray Hubbard;
(4) Streets and parking areas regardless of zoning district;
(5) Agricultural uses such as barns and arenas regardless of zoning district;
(6) Multi-family properties having three or more dwelling units located within one tract or one lot regardless of zoning district; and
(7) Sports fields, courts and related facilities regardless of zoning district classification.
OUTDOOR LIGHTING. Temporary or permanent lighting that is installed, located, or used in such a manner to cause illumination outdoors. Non-residential fixtures that are installed indoors that cause illumination outside are considered outdoor.
OUTDOOR LIGHTING PLAN OR PHOTOMETRIC PLAN. A submittal required with non-residential building permit applications that includes the location of all existing and proposed light fixtures, a lighting fixture table, building elevations indicating where light fixtures are to be installed, a site plan depicting the area to be illuminated, photometric measurements that comply with the requirements of this chapter, measures to minimize trespass, glare, and an applicant certification as provided in § 98.10.
PUBLIC OUTDOOR LIGHTING. All city public street lighting and outdoor lighting on other city property and city owned rights-of-way.
RESIDENTIAL PROPERTY. All property other than non-residential property as defined above.
SIGHT TRIANGLE. A triangle at an intersection formed by two roads or rights-of-way and a third line, which must be kept clear of obstructions for safe motor vehicle operation and pedestrian safety. There shall be two different sight triangles as depicted in the city’s Subdivision Ordinance: one shall be for public and/or private street intersections and the other for the intersection of private non-single family driveways with public or private streets.
TEMPORARY LIGHTING. Lighting intended for uses which by their nature are of limited duration provided the lights are positioned so they do not shine in the eyes of passing drivers; for example, holiday decorations, festivals, civic events, construction projects, performances, and emergency response. Temporary lighting is limited to 45 days or longer as permitted in writing by the Building Official. On the forty-sixth day and beyond a lighting permit is required.
