Western Character.

The list below identifies some traditional building and roof forms that reflect
Western Character:

• Simple rectilinear boxes, especially those of commercial and retail-
oriented uses. Other roofs are flat, or have a gabled roof that is
concealed with a false front.
• Institutional buildings, including churches, often have distinctive, These curvilinear building accents are
not subordinate to the rectilinear form

• Lodging facilities often have sloping roofs, of gable or hipped forms.

Area 1 & Area 2 Design Guidelines:
1.13 Use a simple building form for a new building or addition.

subordinate to the overall form. Appropriate ways to vary the form
include:
» Varying height to reflect different building modules
» Increasing the setback for a portion of the front wall
For a larger building, divide it into
» Stepping back an upper floor to maintain a lower scale at the smaller modules that reflect the scale
