107-241 - Special provisions for arterials LAST AMENDED 12/5/2024 Along those #streets# designated as #arterials#, the following regulations shall apply: (a) Access restrictions Curb cuts are not permitted along an #arterial# #street# on #zoning lots# with frontage on an improved non-#arterial# #street#. For #zoning lots# with frontage only on an improved #arterial# #street#, one curb cut is permitted along such #arterial# #street#. For purposes of this Section, adjoining #zoning lots# in the same ownership or control on November 2, 2023, shall be treated as a single #zoning lot#. For any #zoning lot# which includes an #area plan# approved by the City Planning Commission, no curb cut shall be allowed except where a curb cut is designated on such #area plan#. Such access restrictions with regard to curb cuts shall not apply to #schools#, hospitals and related facilities, police stations, or fire stations. For a #zoning lot# with no less than 100 feet of frontage on an #arterial# #street#, the Commissioner of Buildings may approve curb cuts that exceed the access restrictions listed above where the Commissioner of Transportation submits a letter certifying that such additional curb cuts are necessary to avoid adverse effects on the traffic operations and safety of the #arterial#, or that such curb cuts will not adversely affect traffic operations and safety on the #arterial# including, but not limited to, all curb cut locations on an #arterial# #street# by either implementing a traffic pattern serving right-turn only movements or the implementation of traffic signalization, or other reasons acceptable to the Commissioner of Transportation. (b) #Building# setback In all districts excluding #Commercial Districts#, along portions of the #arterials#, as indicated on the District Plan (Maps 2.1 through 2.4 in Appendix A of this Chapter), a 20 foot #building# setback shall be provided for the full length of the #front lot line# #abutting# such #arterial#. The front #building# setback area shall be unobstructed from its lowest level to the sky except as permitted by this Section. Where a front #building# setback area at least 35 feet in depth is provided, such setback area may be used for required #accessory# off-street parking or loading facilities. No portion of such required setback area may be used for open storage. In the case of the service roads of the West Shore Expressway, a 30 foot #building# setback shall be provided and required off-street parking and loading facilities are permitted within such setback. Within the required front #building# setback, there shall be provided one tree of three-inch #caliper# or more, pre-existing or newly planted, for each 400 square feet of such front open area, unless waived pursuant to the provisions of paragraph (c) of Section 107-483 (Planting and screening for parking areas). The trees shall be selected in accordance with the provisions of Section 107-32 (Tree Requirements).
