§ 14.04.252 Definitions.

Cut-off angle (of a luminaire).
The angle, measured up from the nadir, between the vertical axis and the first line of sight at which the bare source is not visible.
Footcandle.
A unit of illuminance amounting to one (1) lumen per square foot.
Full cut-off type fixture.
A luminaire or light fixture that, by design of the housing, does not allow any light dispersion or direct glare to shine above a ninety degree (90°) horizontal plane from the base of the fixture. Full cut-off fixtures must be installed in a horizontal position as designed, or the purpose of the design is defeated.
Fully shielded.
A fully shielded luminaire is a luminaire constructed or shielded in such a manner that all light emitted by the luminaire, either directly from the lamp or indirectly from the luminaire, is projected below the horizontal plane through the luminaire's lowest light-emitting part as determined by photometry test or certified by the manufacturer. Fixtures will be installed in a horizontal position as designed, or disability glare will result.
Glare.
The sensation produced by luminance within the visual field that is sufficiently greater than the luminance to which the eyes are adapted to cause annoyance, discomfort, or loss in visual performance and visibility.
Illuminance.
The quantity of light, or luminous flux, arriving at a surface divided by the area of the illuminated surface, measured in lux or footcandles.
Light trespass.
Light emitted by a lighting installation which falls outside the boundaries of the property on which the installation is sited.
Luminaire.
A complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps and to connect the lamps to the power supply.
Luminance.
The physical quantity corresponding to the brightness of a surface (e.g., a lamp, luminaire, sky, or reflecting material) in a specified direction. It is the luminous intensity of a area of the surface divided by that area. The unit is candela per square meter.
Lux (lx).
The SI unit of illuminance. One (1) lux is one (1) lumen per square meter.
Obtrusive light.
Spill light which, because of quantitative, directional or spectral context, gives rise to annoyance, discomfort, distraction or a reduction in the ability to see essential information.
Spill light.
Light emitted by lighting installation that falls outside the boundaries of the property on which the installation is sited.
Up-lighting.
Any light source that distributes illumination above a ninety degree (90°) horizontal plane.

§ 14.04.432 Definitions.

For purposes of this division, the following terms shall have the respective meanings as ascribed to them:
Ambient sound.
All sound present in a given environment, being usually a composite of sounds from many sources near and far. It includes intermittent noise events, such as, from aircrafts flying over, dogs barking, wind gusts, mobile farm or construction machinery, and the occasional vehicle traveling along a nearby road. The ambient also includes insect and other nearby sounds from birds and animals or people. The nearby and transient events are part of the ambient sound environment but are not to be considered part of the long-term background sound. If present, a different time or location should be selected for determining the ambient background sound levels.
Biological/environmental assessment.
An assessment performed by a degreed biologist of the on-site and surrounding area habitat and the wildlife species that may be utilizing the project site or neighboring areas for foraging, nesting, breeding, or migratory purposes that may be impacted through development actions; the assessment usually includes identification of wetland, creek, river, bay, and other watershed habitats, and may be species specific.
Building/structurally-mounted wind energy system.
A small wind energy system for permanent mounting and operating on a building or other structure. Building or structurally-mounted systems must not exceed ten kilowatts (10) kW in manufacturer rated power.
dbA (A-weighted sound level).
A measure of overall sound pressure level designed to reflect the response of the human ear, which does not respond equally to all frequencies. It is used to describe sound in a manner representative of the human ear's response.
dbC (C-weighted sound level).
Sound measurement used to measure low frequencies as a single number that represents the entire low frequency spectrum. A-weighted sound levels (dbA) de-emphasize and do not fully represent dbC sound levels when taken or recorded.
Fall radius.
The fall area for a wind energy system is measured by using the total system height of the tower as the radius around the center point of the base of the tower.
Flicker.
The visible flicker effect when rotating turbine blades cast shadows on the ground and nearby structures causing the repeating pattern of light and shadow.
Grid system.
The transmission system created to balance the supply and demand of electricity for consumers.
Horizontal axis wind energy system.
A wind energy system that utilizes the shaft of the monopole to support the propeller at the top and the generator is situated perpendicular and horizontal to the shaft.
Large wind energy system.
A wind energy conversion system consisting of one wind turbine and designed to supplement other electricity sources for existing buildings or facilities, from which the power generated is used for on-site consumption. A large wind energy conversion system consists of a wind turbine, a tower, base, rotor blades, and associated control or conversion electronics and has a total rated capacity that is at least one hundred kilowatts (100 kW) but less than two hundred fifty kilowatts (250 kW).
Medium wind energy system.
A wind energy conversion system consisting of one wind turbine and designed to supplement other electricity sources for existing buildings or facilities, from which the power generated is used for on-site consumption. A medium wind energy conversion system consists of a wind turbine, a tower, base, rotor blades, and associated control or conversion electronics, which has a total rated capacity that is greater than ten kilowatts (10 kW) but less than one hundred kilowatts (100 kW).
Rated capacity.
The maximum rated output of electric power production equipment. This output is typically specified by the manufacturer with a "nameplate" on the equipment.
Small wind energy system.
A single system designed to supplement other electricity sources for existing buildings or facilities, from which the power generated is used for on-site consumption. A small wind energy conversion system consists of a single wind turbine, a tower, base, rotor blades, and associated control or conversion electronics, which for the purpose of this division has a total rated capacity of ten kilowatts (10 kW) or less.
Survival wind speed.
The maximum wind speed, as designated by the wind energy system manufacturer, at which a system, in unattended operation (not necessarily producing power) is designed to survive, without damage to any structural equipment or components of the system, or loss of the ability to function normally.
Tonal or "pure" sounds.
Sound that is defined as sound at discrete frequencies. It is caused by components such as meshing gears, nonaerodynamic instabilities interacting with a rotor blade surface, or unstable flows over holes or slits or a blunt trailing edge. A highly tonal sound is often described as a buzz, whine, or hum.
Total wind energy system height.
The distance from the grade to the highest point on the tower, including the vertical length of any extensions, such as the rotor blade:
(1) 
For horizontal axis wind energy system towers, the distance between the ground and the highest point of the rotor blade in its vertical, upright position; and
(2) 
For vertical axis wind energy system towers, the distance between the ground and the highest point of the monopole tower/shaft.
Turbine, guyed.
Any tower or wind energy system turbine supported in whole or in part by cables anchored to the ground.
Vertical axis wind energy system.
A wind energy system that utilizes a generator positioned at the base of the tower and has the blades wrapped around the shaft.
Wind energy system or wind energy conversion system.
A shaft, gearing belt, or coupling utilized to convert the rotation of the surface area into a form suitable for driving a generator, alternator, or other electricity producing device to convert the mechanical energy of the surface area into electrical energy, and the associated, tower, pylon, and rotor blades or other device.
