43-46 - Height and Setback Provisions for Districts With an A Suffix LAST AMENDED 6/6/2024 For M Districts with an A suffix, a #building or other structure# shall not exceed the maximum base heights or maximum #building# height set forth in paragraph (a) of this Section. A setback is required for all portions or #buildings or other structures# that exceed the maximum base height specified in paragraph (a) and shall be provided in accordance with paragraph (b). In districts without a maximum height limit, the tower provisions set forth in paragraph (c) shall apply. (a) Maximum base heights and maximum #building# heights The table below sets forth the maximum base heights and maximum #building or other structure# heights. MAXIMUM BASE HEIGHT AND MAXIMUM BUILDING HEIGHT Maximum Height of #Buildings Maximum Base Height (in District or other Structures# (in feet) feet) M1-1A M2-1A M3- 45 65 1A M1-2A M2-2A M3- 65 95 2A M1-3A M2-3A 95 125 M1-4A M2-4A 125 155 M1-5A 155 205 M1-6A 155 245 M1-7A 155 325 M1-8A M1-9A 155 N/A In addition, for #zoning lots# with a #lot area# greater than or equal to 20,000 square feet, a #building# may exceed the maximum building heights established in such table by 25 percent. (b) Any portion of a #building# above the maximum base height shall provide a setback with a depth of at least 10 feet from any #street wall# fronting on a #wide street# and a depth of at least 15 feet from any #street wall# fronting on a #narrow street#. However, such setback requirement may be modified as follows: (1) the depth of such required setback may be reduced by one foot for every foot that the #street wall# is located beyond the #street line#, but in no event shall a setback of less than seven feet in depth be provided, except as otherwise set forth in this Section. To allow #street wall# articulation, where a #street wall# is divided into different segments and located at varying depths from the #street line#, such permitted setback reduction may be applied to each #street wall# portion separately; (2) the depth of such required setbacks may include the depth of recesses in the #street wall# of the #building# base, provided that the aggregate width of any such recessed portion of a #street wall# with a setback less than seven feet, does not exceed 30 percent of the #aggregate width of #street wall# at any level; (3) these setback provisions are optional for any #building that either is located beyond 50 feet of a #street line# or oriented so that lines drawn perpendicular to it, in plan, would intersect a #street line# at an angle of 65 degrees or less. In the case of an irregular #street line#, the line connecting the most extreme points of intersection shall be deemed to be the #street line#; and (4) dormers may penetrate a required setback area, provided that the aggregate width of all dormers at the maximum base height does not exceed 40 percent of the width of the #street wall# of the highest #story# entirely below the maximum base height#. Such dormers need not decrease in width as the height above the maximum base height increases. (c) Towers For #buildings# in M1-8A and M1-9A Districts, no maximum height limit shall apply. However, any portion of a #building# above a height of 350 feet shall have a maximum #lot coverage# of 50 percent of the #lot area# of the #zoning lot#.
