Outdoor lighting. All parking, loading and unloading areas and walkways thereto and appurtenant passageways and driveways serving commercial uses open to the public shall be illuminated adequately during the hours between sunset and sunrise when the use is in operation. The lighting plan in and around the parking areas shall provide for nonglare, color-corrected lights focused downward. The light intensity provided at ground level shall be a minimum of 0.3 footcandle anywhere in the areas to be illuminated, shall average a minimum of 0.5 footcandle over the entire area, and shall be provided by fixtures with a maximum mounting height of 25 feet measured from the ground level to the center line of the light source or the height of the building, if attached, whichever is lower, and spacing not to exceed five times the mounting height. Any other outdoor lighting, such as building and sidewalk illumination and driveways with ornamental light, shall be shown on the lighting plan in sufficient detail to allow determination of the effects to adjacent properties, traffic safety and overhead sky glow. No light shall shine directly into windows of off-site buildings or unto streets and driveways in such a manner as to interfere with or distract driver vision. To achieve these requirements, the intensity of such light sources, light shielding and similar characteristics shall be subject to site plan approval.
