(a) Lighting Plans. Full lighting plans shall be required prior to the installation of any lighting improvements or fixtures. Lighting plans shall show the following:
(1) The location and height above grade of the luminaires.
(2) The lumens and type of each light source such as incandescent, fluorescent, metal halide, etc.
(3) The general type and appearance of each luminaire such as lantern, globe, floodlight, full-cutoff area luminaire, wall pack, downlight, etc.
(4) Calculated or manufacturer-rated numerical values of total light output (lumens) of the luminaire or luminaires and the light output above a horizontal plane through the optical center of the luminaire if the light output per lamp is greater than allowed by this regulation.
(5) Building walls to be illuminated by wall mounted or facade-mounted luminaires in conformance with Section 1161.05(c) including relevant building elevations showing the location of the luminaires, their aiming direction and aiming angle (if directional), the portions of the building walls to be illuminated, and their color.
(b) Light Trespass. An exterior lighting system is considered to produce excessive light trespass when the light source (the light emitting portion of the lamp) is visible from normal viewing positions on an adjoining property and the maximum light output per lamp is greater than allowed by Section 1161.05.
(c) Light Pollution. An exterior lighting system is considered to contribute excessively to light pollution when light is emitted above a horizontal plane through the optical center of the luminaire and if the maximum light output per lamp is greater than allowed by Section 1161.05.
(d) Glare. An exterior lighting system is considered to produce glare when the light source inside the luminaire is visible as seen from normal viewing positions whether or not the light from the source is diffused or refracted by lens optics, and the light output per lamp is greater than allowed by Section 1161.05.
(e) Lighting Controls. To minimize the amount of light trespass, light pollution, excess lighting and energy use at night, unnecessary lighting shall be switched off. The use of photocell or photocell/timer switches which allow lighting to operate all night is prohibited. Motion sensor switches which turn lights on only when activated by motion and only for a set period of time after motion ceases are permitted.
