The area between the #Barge Basin# and such #street lines# shall be improved as publicly accessible areas in accordance with the applicable provisions of Section 144-30 (SPECIAL PUBLIC ACCESS AREA REGULATIONS), inclusive. (2) Along the short dimension of the #Barge Basin# Along the short dimension of the #Barge Basin#, the southeasterly boundaries of the Barge Basin Subdistrict, including the boundary extending from the centerline prolongation of Taylor Street, and the boundary constructed from an offset of the southeastern terminus of the #Barge Basin#, shall be considered #street lines#. Within the area between the #Barge Basin# and such #street lines# shall be an area adjacent to the short dimension of the #Barge Basin# that connects the Barge Basin East Subarea pedestrian esplanade and the Barge Basin West Subarea pedestrian esplanade that shall be: (i) improved as a sidewalk to Department of Transportation standards; (ii) at the same level as the adjoining public sidewalk; and (iii) accessible to the public at all times the public access areas are required to be open to the public, pursuant to Section 144-33 (Hours of Operation).

(c) #Street wall# location, and articulation At least 70 percent of the #aggregate width of street walls# facing #Barge Basin# shall be located within eight feet of the #street line# and shall extend to at least a minimum base height of 30 feet, or two #stories#, whichever is lower. The remaining #aggregate width of street walls# may be recessed beyond eight feet of the #street line#, provided that any recesses deeper than 10 feet are located within an #outer court#. Any open area between a #street wall# and the #street lines# along #Barge Basin# that is within eight feet of such #street line# shall be improved as publicly accessible areas in accordance with the applicable provisions of Section 144-30, inclusive. Open areas between the #street line# and #street walls# that are beyond eight feet of such #street line# may be publicly accessible areas, as needed, to achieve the minimum percentage of public access area required by each Subarea pursuant to Section 144-31 (Required Public Access Area). For those portions of #buildings# facing #Barge Basin# with a #street wall# width exceeding 200 feet, a minimum of 20 percent of the surface area of such #street wall# up to the height of the second #story#, or 30 feet, whichever is lower, and a maximum of 50 percent of such surface area, shall either recess or project from the remaining surface area of the #street wall# by a minimum of three feet. #Building# projections shall be a permitted obstruction within any open area between the #street wall# and #street line#, including publicly accessible areas, provided that the minimum percentage of public access area required by each Subarea pursuant to Section 144-31 remains open to the sky. Additional permitted obstructions are allowed in accordance with paragraph (a) of Section 144-32 (Design Requirements).

(2) Dormers Along the #Barge Basin# frontages, dormers shall be a permitted obstruction within an #initial setback distance#, provided that: (i) the depth of such dormers does not exceed 10 feet for #buildings# fronting along the northeastern boundary of the #Barge Basin# or 20 feet for #buildings# fronting along the southwestern boundary; (ii) the #street wall# width of such dormer does not exceed 30 percent of the #street wall# width of the #building# above the maximum base height; and (iii) the #street wall# width of such dormer along a single tower does not exceed 100 feet.
