In the districts indicated, and for C1 or C2 Districts mapped within an R1 through an R5 District, all developments on portions of a zoning lot landward of the shoreline or on platforms shall be subject to the underlying height and setback regulations, except as modified by the provisions of this Section. 

1. Modified base height and building heights in certain districts
   
   The maximum base height and maximum building height for buildings on waterfront blocks for certain districts shall be as set forth in the following table: 
    

   MAXIMUM BASE HEIGHT AND MAXIMUM BUILDING HEIGHT FOR RESIDENTIAL BUILDINGS ON WATERFRONT BLOCKS

   R3 C1 or C2 mapped within R3 C3	35	45
   R4 C1 or C2 mapped within R4	45	55
   R5 C1 or C2 mapped within R5 C4-1	55	65

2. Additional regulations
   1. Above the maximum base height, a building shall be set back at least:
      1. 15 feet from a narrow street line;
      2. 10 feet from a wide street line; or
      3. 30 feet from the boundary of a shore public walkway. Wherever a supplemental public access area is provided as a widened shore public walkway, such widened area shall be included in the initial setback distance.
          

          Dormers provided in accordance with Section 23-413 shall be permitted within any setback area, provided that the depth of encroachment of a dormer facing the shore public walkway shall not exceed 15 feet; 

   2. Any portion of a predominantly community facility building that exceeds a height of 35 feet shall be set back at least 25 feet from a front yard line or street line, where applicable, and no portion of such building shall exceed a height of 60 feet. However, within a large-scale community facility development, for portions of a building that are located at least 100 feet from a street line and, on a waterfront zoning lot, 100 feet from a waterfront yard, the maximum height shall not exceed 100 feet.
   3. All structures other than buildings shall be limited to a height of 35 feet, except that in C4-1, C8-1 and M1-1 Districts, freestanding wind energy systems shall be permitted to a height of 85 feet, as measured from the base plane to the highest point of the wind turbine assembly.
