COMMERCIAL. Any property zoned Commercial or Manufacturing by the city.
EMERGENCY CONDITIONS. Generally, lighting only energized during an emergency; lighting fed from a backup power source; or lighting for illuminating the path of egress solely during a fire or other emergency; or, lighting for security purposes used solely during an alarm.
FULLY SHIELDED. A fixture constructed and installed in such a manner that all light emitted by the fixture, either directly, or indirectly, by reflection or refraction from any part of the lighting, is projected below the horizontal plane through the fixture’s lowest light-emitting part.
GLARE. Lighting entering the eye directly from fixtures or indirectly from reflective surfaces that causes reduced visibility.
GREENBELT. An area of open land around a city on which building is restricted.
HOLIDAY OR FESTIVE LIGHTING. Temporary or permanent lighting installed and operated in connection with holidays or traditions (for example, LED lighting systems, LED miniatures, or C-7 or C-9 bulbs). Floodlights for the purpose of illuminating a display that does not trespass on adjoining properties.
LAMP. A generic term for a source of optical radiation (for example, light), often called a BULB or TUBE. Examples include incandescent, fluorescent, or high-intensity discharge (HID) lamps and low-pressure sodium (LPS) lamps, and light-emitting diode (LED) modules and arrays.
LANDSCAPE LIGHTING. Lighting of trees, shrubs, or other plant material and ponds, and other landscape features.
LIGHT POLLUTION. Any adverse effect of artificial light including, but not limited to, glare, light trespass, sky glow, compromised safety and security, and impacts on the nocturnal environment.
LIGHT TRESPASS. Light that falls upon any adjacent property(s).
LIGHTING. Electric or human-made, or artificial, lighting.
LUMEN. The unit of measurement used to quantify light produced by a lamp (bulb) or emitted from a lighting (as distinct from “watt,” a measure of power consumption).
MOUNTING HEIGHT. The height of the photometric center of a lighting above grade level.
NEW USE. In Commercial Zones, a NEW USE shall be a change in the business occupying the primary structure or the issuance of a conditional use permit on the property. In Residential and Agricultural Zones, a NEW USE is the issuance of a home occupation license or conditional use permit on the property.
NONCONFORMING LIGHTING. Lighting legally installed before the date of enactment of this subchapter but not conforming to the provisions of this subchapter.
OUTDOOR LIGHTING. Lighting equipment installed within the property line and outside the building envelopes, whether attached to poles, building structures, the earth, or any other location; and any associated lighting-control equipment.
PARTLY SHIELDED. A fixture with an opaque top and translucent or perforated sides designed to emit most light downward.
SHIELDED DIRECTIONAL FIXTURE. A fixture that includes an adjustable mounting device allowing aiming in any direction and contains a shield, louver, or baffle to reduce direct view of the lamp.
SIGN. Advertising, directional, or other outdoor promotional display of art, words, and/or pictures.
SKY GLOW. The brightening of the nighttime sky that results from scattering and reflection of artificial light by moisture and dust particles in the atmosphere. SKY GLOW is caused by light directed or reflected upwards or sideways, and reduces one’s ability to view the night sky.
TEMPORARY LIGHTING. Lighting installed and operated for periods not to exceed 60 days, completely removed and not operated again for at least 30 days.
TRANSLUCENT. Allowing light to pass through, diffusing it so objects beyond cannot be seen clearly (not transparent or clear).
UNSHIELDED. A fixture capable of emitting light in any direction, including downwards, or does not include a shield, louver, or baffle to reduce direct view of the lamp.
