(B)
In considering an application for a certificate of appropriateness, the
Commission shall be guided by the following general
standards in addition to any design criteria in this Chapter and in the
ordinance designating the landmark or historic district:
(1)
Every reasonable effort shall be made to provide a compatible use for a
property that requires minimal alteration of the building, structure,
site or object and its environment, or to use a property for its originally intended
purpose;
(2)
The distinguishing original qualities or character of a building, structure,
or site and its environment shall not be destroyed. The removal or
alteration of any historic material or distinctive architectural feature
should be avoided when possible;
(3)
All buildings, structures, and sites shall be recognized as products of their
own time. Alterations that have no historical basis and that seek to
create an earlier appearance shall be discouraged;
(4) Changes
that may have taken place in the course of time are evidence of the history
and development of a building, structure, or site and its
environment. These changes may have acquired significance in their own right, and this
significance shall be recognized and respected;
(5)
Distinctive stylistic features or examples of skilled craftsmanship that
characterize a building, structure, or site shall be treated with
sensitivity;
(6)
Deteriorated architectural features shall be repaired rather than replaced,
wherever possible. In the event replacement is necessary, the new
material should match the material being replaced in composition, design, color,
texture, and other visual qualities. Repair or replacement of missing
architectural features should be based on accurate duplication of
features, substantiated by historic, physical, or pictorial evidence, rather
than on conjectural designs or the availability of different
architectural elements from other buildings or structures;
(7)
The surface cleaning of structures shall be undertaken with the gentlest
means possible. Sandblasting and other cleaning methods that will
damage the historic building material shall not be undertaken;
(8)
Every reasonable effort shall be made to protect and preserve archeological
resources affected by, or adjacent to, any project;
(9)
Contemporary design for alterations and additions to existing properties
shall not be discouraged when such alterations and additions do not
destroy significant historical, architectural, or cultural material, and such design is compatible
with the size, scale, color, material, and character of the property,
neighborhood, or environs.
