§ 155.137 SITE ORIENTATION AND DIRECTIONAL EXPRESSION.
   An important factor affecting the character of a historic district concerns the relationship between a historic building and its orientation toward adjacent structures and the street. An orderly rhythm in site orientation and directional expression can also lend harmony to a historic district and evoke a stronger sense of its historical character.
   (A)   Setbacks.
      (1)   In addition to the setback regulations prescribed in Chapter 156 of this code of ordinances, the street-facing facade of new and reconstructed buildings in the Commercial Landmark District should be erected in line with the street-front setback of existing buildings from the historic period on the same block.
      (2)   The street-facing facade of new and reconstructed buildings in the Commercial Historic District should be erected in line with the street-front setback of existing buildings from the historic period.
   (B)   Directional expression.
      (1)   To preserve the continuity prevailing along most block faces in the city, the principal facade of new or reconstructed buildings should be oriented parallel to the street it faces.
      (2)   The principal facade should be oriented parallel to the street it faces.
   (C)   Front yard additions. To preserve the orderly rhythm of front yard spacing and the architectural integrity of street-facing facades, front yard additions to existing buildings in the Residential Historic District should be generally discouraged when such construction will alter or obscure the street-facing facade of a building that has been designated as contributing to the character of the historic district, or if the construction of the addition will result in a street-facing setback of less than 80% of the average setback of existing buildings from the historic period on the same block.
