1470.17  PRESERVATION OF HISTORIC FEATURES.
   (a)   Every reasonable effort shall be made to provide a compatible use for a resource which requires minimal alteration of the building, structure or site and its environment, or to use the resource for its originally intended purpose.
   (b)   The distinguishing original qualities or character of a resource and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural features shall be avoided when possible.
   (c)   All resources shall be recognized as products of their own time. Alterations that have no historic basis and which seek to create an earlier appearance shall be discouraged.
   (d)   Changes which may have taken place in the course of time are evidence of the history and development of a resource and its environment. These changes may have acquired significance in their own right, and this significance shall be recognized and respected.
   (e)   Distinctive stylistic features or examples of skilled craftsmanship which characterize a resource shall be treated with sensitivity.
   (f)   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 duplications of features, substantiated by historic, physical or pictorial evidence rather than on conjectural designs or the availability of different architectural elements from other resources.
   (g)   The surface cleaning of resources shall be undertaken with the gentlest means possible. Sandblasting and other cleaning methods that will damage the historic materials shall not be undertaken.
   (h)   Every reasonable effort shall be made to protect and preserve archaeological resources affected by or adjacent to any project.
   (i)   Contemporary design for alterations and additions to existing resources shall not be discouraged when such alterations and additions do not destroy significant historic, architectural or cultural material and when such design is compatible with the size, scale, color, material and character of the property, neighborhood or environment.
   (j)   Whenever possible, new additions or alterations to resources shall be done in such a manner that if such additions or alterations were to be removed in the future, the essential form and integrity of the resource would be unimpaired.
