Public plazas shall be illuminated to provide for safe use and enjoyment of all areas of the public plaza. Special attention should be provided in lighting steps and other changes in elevation and areas under tree canopies and permitted canopies within the public plaza.

Public plazas shall be illuminated with a minimum level of illumination of not less than two horizontal foot candles (lumens per foot) throughout all walkable and sitting areas, including sidewalks directly adjacent to the public plaza, and a minimum level of illumination of not less than 0.5 horizontal foot candles (lumens per foot) throughout all other areas. All lighting sources used to satisfy this illumination requirement shall be located outdoors on the subject zoning lot. Such level of illumination shall be maintained from one hour before sunset to one hour after sunrise, including public plazas that are authorized to close at night. A lighting schedule, including fixtures, wattage and their locations and designs together with a diagram of light level distribution, with light levels indicated at intervals of no more than every 20 square feet, shall be part of the required detailed design plans. Electrical power shall be supplied by one or more outlets furnishing a total of at least 1,200 watts of power for every 4,000 square feet, or fraction thereof, of the area of a public plaza.

All lighting sources that illuminate the public plaza and are mounted on or located within buildings adjacent to the public plaza shall be shielded from direct view. In addition, all lighting within the public plaza area shall be shielded to minimize any adverse effect on surrounding residences.
