128-40 Mandatory Improvements
Sidewalks with a depth of at least 12 feet, measured perpendicular to the curb of a street, shall be provided along the entire street frontage of a zoning lot. In locations where the width of the sidewalk within the street is less than 12 feet, a sidewalk widening shall be provided on the zoning lot so that the combined width of the sidewalk within the street and the sidewalk widening equals 12 feet. However, existing buildings to remain on the zoning lot need not be removed in order to comply with this requirement. All sidewalk widenings shall be improved to Department of Transportation standards for sidewalks, shall be at the same level as the adjoining public sidewalks, and shall be accessible to the public at all times.
The entire area of the zoning lot between the street line or sidewalk widening line, where applicable, and all street walls of the building and their prolongations, shall be planted at ground level, or in raised planting beds that are permanently affixed to the ground, except that such plantings shall not be required at the entrances to, and exits from, the building, within driveways accessing off-street parking spaces located within, to the side, or rear of such building, or between commercial uses and the street line. No zoning lot shall be altered in any way that will either create a new non-compliance or increase the degree of non-compliance with the provisions of this Section.
The designated locations for visual corridors, as defined in Article VI, Chapter 2, are shown on Map 5 in the Appendix to this Chapter. Such visual corridors shall be provided in accordance with the standards of Sections 62-512 (Dimensions of visual corridors) and 62-513 (Permitted obstructions in visual corridors), except that:
(a) lighting fixtures in visual corridors shall be considered permitted obstructions; and
(b) within the visual corridor provided through Parcel 2 to the Pierhead line within the flexible location zone indicated on Map 5, a portion of a building shall be a permitted obstruction, provided that such obstruction is located no more than 14 feet above the reference plane of the visual corridor, and that such obstruction occupies no more than 185,000 cubic feet in total above the reference plane of the visual corridor.
