§ 153.424 ADDITIONAL DESIGN STANDARDS.
   (A)   Facade articulation.
      (1)   Intent. To create visually interesting and human-scaled facades, particularly those that face streets or open spaces and avoid large areas of undifferentiated facades.

         (a)   A change in color;
         (b)   A change in material or material module or pattern;
         (c)   A system of horizontal and vertical scaling elements such as a belt course, string course, projecting fins, or projecting cornice or eye brow;
