1. Shallow #zoning lots#
   
   The maximum #lot coverage# for shallow #interior# or #through lots# may be increased as follows:
   
   
   1. For shallow #interior lots#
      
      In the districts indicated, if an #interior lot# was owned separately and individually from all other adjoining tracts of land, both on December 15, 1961, and on the date of application for a #building permit#, and is less than 90 feet deep at any point, the maximum #lot coverage# of such #zoning lot#, or portion thereof, may be increased by one percent for every five feet the depth of such #zoning lot#, or portion thereof, is less than 90 feet. Where the #front lot line# or #rear lot line# of a #zoning lot# intersects a #side lot line# at an angle other than 90 degrees, the depth of such #zoning lot#, or portion thereof, shall be measured at the midpoint of such irregularly angled #lot line#.

   4. For #zoning lots# with shallow portions
      
      Where a portion of a #zoning lot# is less than 90 feet for an #interior lot#, or 180 feet for a #through lot#, an adjusted maximum #lot coverage# shall be established for the #zoning lot# by multiplying the maximum percent of #lot coverage# permitted for the shallow portion of the #zoning lot# established pursuant to paragraphs (a)(1) or (a)(2) of this Section by the percentage such portion constitutes of the #lot area# of the #zoning lot#, and by multiplying the maximum percent of #lot coverage# permitted for the non-shallow portion of the #zoning lot# established pursuant to Section 23-153 (For Quality Housing buildings) by the percentage such portion constitutes of the #lot area# of the #zoning lot#. The sum of the areas of #lot coverage# thus obtained shall be the adjusted maximum percent of #lot coverage# for the #zoning lot#.
   
   
   5. Maximum coverage
      
      In no event shall the maximum #lot coverage# of an #interior lot# or #through lot# exceed 80 percent. Shallow portions of a #zoning lot# may exceed such maximum, so long as the adjusted maximum #lot coverage# set forth in paragraph (a)(4) of this Section complies with such maximum.
