[R.O. 2011 §405.150; Ord. No. 10-6 §1, 3-8-2010]
A.
Design
guidelines for applying the criteria for review of certificates of
appropriateness shall, at a minimum, consider the following architectural
criteria:
1.
Height. The height of any proposed alteration or
construction should be compatible with the style and character of
the landmark and with surrounding structures in a historic district.
2.
Proportions of windows and doors. The proportions
and relationships between doors and windows should be compatible with
the architectural style and character of the landmark and with sounding
structures within a historic district.
3.
Relationship of building masses and spaces. The
setback and relationship of a structure within a historic district
to the open space between it and adjoining structures should be compatible.
4.
Roof shape. The design of the roof should be compatible
with the architectural style and character of the landmark, and with
surrounding structures in a historic district.
5.
Landscaping. Landscaping should be compatible with
the architectural character and appearance of the landmark and of
surrounding structures and landscapes in historic districts.
6.
Scale. The scale of the structure after alteration,
construction, or partial demolition should be compatible with its
architectural style and character and with surrounding structures
in a historic district.
7.
Directional expression. Facades in historic districts
should blend with other structures with regard to directional expression.
Structures in a historic district should be compatible with the dominant
horizontal or vertical expression of surrounding structures. The directional
expression of a landmark after alteration, construction, or partial
demolition should be compatible with its original architectural style
and character.
8.
Architectural details. Architectural details including
materials, colors, and textures should be treated so as to make a
landmark compatible with its original architectural style and character
and to preserve and enhance the architectural style or character of
a landmark or historic district.
9.
Signage. The character of signs should be in keeping
with the historic architectural character of a landmark or historic
district. Character of a sign includes the number, size, area, scale,
location, type (e.g., off-site advertising signs and on-site business
signs), letter size or style, and intensity and type of illumination.
10.
Minimum maintenance. Significant features should
be kept in a condition of good repair and maintenance. All structural
and mechanical systems should be maintained in a condition and state
of repair that will prevent decay, deterioration or damage to significant
features, or otherwise adversely affect the historic or architectural
character of structures within a historic district.
