The provisions of this Section shall apply to all developments fronting upon locations requiring sidewalk widenings as shown on Map 6 (Sidewalk Widening) in Appendix A of this Chapter. A sidewalk widening is a continuous, paved open area along the street line of a zoning lot having a depth of two feet or five feet, as set forth on Map 6. Such depth shall be measured perpendicular to the street line. Sidewalk widenings shall be improved as sidewalks to Department of Transportation standards, at the same level as the adjoining public sidewalk and directly accessible to the public at all times. No enlargement shall be permitted to decrease the depth of such sidewalk to less than such minimum required total sidewalk depth.

All mandatory sidewalk widenings must provide lighting in accordance with the requirements of Section 37-743, except that the minimum level of illumination shall be not less than two horizontal foot candles throughout the entire mandatory sidewalk widening.
