To create a more interesting and inviting environment, all buildings shall include architectural details, including but not limited to cornices, and window and door trim. Buildings shall be designed with an architectural style that respects the historic character of the Heritage District but adequately accommodates the intended modern uses. When authentic architectural details such as windows and doors are not feasible, simulated openings may be approved.
   (A)   Roof type. The roof types of buildings in the OMG shall be designed in conformance with the following regulations:
      (1)   For approximately every front 60 feet of building facade a variation of roof type is encouraged to reduce visual monotony and assist in development of a human scale environment.
      (2)   Gabled roofs are encouraged; however, other roof types may be approved by the Planning Commission on a case-by-case basis.
      (3)   When gabled roofs are used, the design of the roof pitch may vary, but should not be less than one-quarter of the building height as measured from the grade line to the gutter.
      (4)   When flat roofts are used, decorative cornices and parapet roof lines shall be incorporated.
   (B)   Building entrances. The building entrances in the OMG shall be designed in conformance with the following regulations:
      (1)   When a commercial building has frontage on Montgomery Road or Main Street, the building entrances should be encouraged to face onto Montgomery Road or Main Street when feasible.
      (2)   When a residential building has frontage on Montgomery Road or Main Street, the first floor entrances should be located facing onto Montgomery Road or Main Street when feasible. Access to upper stories from Main Street and Montgomery Roads is strongly encouraged.
      (3)   When a new road is proposed for interior circulation and meets the streetscape standards as detailed in the city’s streetscape plan, buildings may be oriented to face onto these streets and the entrance may also be oriented to these streets.
      (4)   In all cases the main entrance of the building shall be easily identifiable, and should provide an introductory statement for a building using architectural articulation or landscaping or a combination of both.
      (5)   Entrances should be designed to allow individual business to present a clear image without compromising the sense of unity of the facade or development.
   (C)   Windows. Windows in the OMG District shall be designed in conformance with the following regulations:
      (1)   Windows in all structures shall exhibit symmetry and proportion to the building. Individual window proportions shall be more vertical than horizontal, with the height being approximately one and one-half times the width of the window. Display windows on the first floor of commercial structures may be larger and have more of an emphasis on the horizontal dimension.
      (2)   Windows that are visible from a public right-of-way, shall be divided into vertically proportioned components, through multi-part windows or other divided lights. Other than first-floor display windows and bay windows in residential structures, windows should be detailed with architectural elements, such as projecting sills, molded surrounds, lintels, transoms and/or mullions. Grilles in airspace and snap-on grille style windows are prohibited.
      (3)   Window and door openings on the ground floor of a commercial building should occupy no less than 50% of the building’s facade length on any facade facing Montgomery Road or another public street.
      (4)   Windows shall be constructed of clear  glazing and tinted glazing shall not be used.
      (5)   All-vinyl windows are prohibited. Extruded aluminum-clad or vinyl-clad wood windows may be permitted, if appropriate. Composite wood/PVC/fiberglass windows are permitted (i.e. Fibrex).
