LAST AMENDED
12/5/2024

For all #flood-resistant buildings#, the definition of #floor area# may be modified in accordance with the provisions of this Section.

(a)    Entryways

       In all districts, for #buildings# other than #residential buildings# with enclosed entryways below the #first story above the flood elevation#, up
       to 100 square feet of such entryways may be excluded from the definition of #floor area# for each foot of difference between the #first story
       above the flood elevation# and the level of the adjoining sidewalk, provided such floor space complies with the #flood-resistant construction
       standards# for dry-flood-proofing up to the #flood-resistant construction elevation# or higher. However, no more than a maximum of 500
       square feet may be excluded from the definition of #floor area# for each entryway.

       Such exempted floor space shall be considered #floor area# for the purposes of satisfying other ground floor #use# regulations of this Resolution,
       including, but not limited to, limitations on #floor area# for certain #uses#, parking wrap and screening requirements, and requirements for
       #floor area# at the ground floor.

(b)    Flood-proofed ground floors

       (1)    For #buildings# along #primary frontages#, or portions thereof, as defined in Section 64-11, floor space located below the #first story
              above the flood elevation# and within 30 feet of the #street wall# along such #primary frontage# may be excluded from the calculation of
              #floor area#, provided that:

              (i)    such floor space complies with the #flood-resistant construction standards# for dry-flood-proofing up to the #flood-resistant
                     construction elevation# or higher;

              (ii)    the level of the finished floor of such floor space is located no more than two feet above nor two feet below #curb level#;

             (iii)   such floor space shall be limited to non-#residential uses# other than #accessory# parking or #public parking garages# and subject
                     to the minimum depth requirements set forth in Section 37-32 (Ground Floor Depth Requirements for Certain Uses);

              (iv)   #ground floor level# #street walls# shall be glazed in accordance with the provisions set forth in Section 37-34 (Minimum
                     Transparency Requirements); and

              (v)     for #developments#, the level of the #first story above the flood elevation# is 13 feet or more above the level of the adjoining
                     sidewalk.


              However, such floor space shall be considered #floor area# for the purposes of satisfying other ground floor #use# regulations of this
              Resolution, including, but not limited to, limitations on #floor area# for certain #uses#, parking wrap and screening requirements, and
              requirements for non-#residential# #floor area# at the ground floor.

       (2)    In all districts, floor space located below the #first story above the flood elevation# may be excluded from the calculation of #floor area#
              provided such floor space complies with the #flood-resistant construction standards# for wet-flood-proofing up to the #flood-resistant
              construction elevation# or higher.

(c)   #Floor area# for existing #buildings#

       For #zoning lots# containing #buildings# existing prior to May 12, 2021, as an alternative to the #floor area# regulations of this Chapter, the
       amount of #floor area# allocated to a #basement# or #cellar# in such existing #building# may be determined in accordance with how those terms
       were defined prior to May 12, 2021.
