These regulations are established to promote the consistent, orderly development of the community, to preserve property values and to protect and enhance the character of the city’s visual environment. The requirements of this section are not intended to regulate structural quality, workmanship or the various performance and maintenance characteristics of the various materials listed in the following schedule.
(B) Applicability. All exterior wall materials installed in the Zoning Districts listed below shall comply with the Schedule Regulating Exterior Wall Building Materials. For purposes of this Schedule the Zoning Districts shall be grouped in the following categories.

(4) Chimneys located on exterior walls of a multiple-family residential structure shall be treated with face brick or stone on 100% of all exposed surfaces. The Planning Commission may grant an exception when the brick or stone would, in the opinion of the Planning Commission, be incompatible with or detract from the overall architectural design.
(5) On the side of the structure where the garage door is located the exterior wall surface above the garage door shall be treated with the same material as the remainder of the wall adjacent to the door.
(6) The rear elevation of all multiple-family residential structures shall provide at least 1 horizontal offset of at least 4 feet to provide for three-dimensionality to the facade. The rear-roofline configuration shall also provide similar vertical offsets.

(8) (a) Where the developer is proposing homes which reproduce specific historical periods in order to create a theme (e.g. traditional New England Colonials or Saltbox, Victorian, Queen Ann, Early American Bungalow or Farmhouse Styles), the Planning Commission may vary the standards in this schedule in order to create a unique and creative design theme.
(b) For commercial, office and industrial buildings and/or developments, the Planning Commission may approve modifications to these standards to achieve a specific architectural objective as demonstrated by the project sponsor in meeting the overall development objectives of the community.
