(a) Lighting Plans. Full Lighting Plans shall be required prior to installation of any Exterior lighting improvements or fixtures. Full Lighting Plans shall contain all of the following:
(1) The location and height above grade of the luminaires;
(2) The wattage 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 cut-off 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 chapter; and
(5) Building walls which are to be illuminated by wall-mounted or facade- mounted luminaires shall be in conformance with Section 1165.04(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 system is considered to produce excessive light trespass when the lighting source or sources (the light emitting portion of the lamp) is:
(1) Visible from normal viewing positions on an adjacent property and the maximum light output per lamp is greater than allowed by Section 1165.05; and/or
(2) The total light trespass over a property line shall be limited to no more than 0.5 footcandle at the property line. All on-site lighting of buildings, landscaping, and parking areas shall be designed so as not to shine onto any adjacent property or building, or to cause glare that projects onto any public street or into any vehicle thereon.
(c) Measurement. All light levels shall be measured in footcandles with a direct- reading, portable light meter. Readings shall be taken only after the unit has been exposed long enough to take a constant reading. Measurements shall be taken at the property line, along a horizontal plane at a height of three and one-half feet above the ground.
(d) 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 1165.05.
(e) 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 1165.05.
(f) 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 shall be permitted but only for a set period of time not to exceed three (3) minutes after the motion ceases.
