§ 18.01.080. Criteria for approval of a certificate of appropriateness.
The following standards, guidelines and criteria should be used in a balanced evaluation of the property in question:
A.
The HPB shall follow the secretary of the interior's standards for rehabilitation and guidelines for rehabilitating historic buildings to assist in its consideration of all applications for certificates of appropriateness. These standards and guidelines shall be made available to property owners of historic landmarks or within a district zoned historic or with a historic overlay. In addition to the guidelines set forth by the secretary of the interior's standards for rehabilitation the following additional criteria shall apply in reviewing an application for a certificate of appropriateness:
1.
Every reasonable effort shall be made to adapt the property in a manner which requires minimal alteration of the building, structure, object or site and its environment.
2.
The distinguishing original qualities or character of a building, structure, object, or site and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural features should be avoided when possible.
3.
All buildings, structures, objects, and sites shall be recognized as products of their own time. Alterations that have no historical basis and which seek to create an earlier appearance shall be discouraged.
4.
Changes which may have taken place in the course of time are evidence of the history and development of a building, structure, object, 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 which characterize a building, structure, object, or site shall be kept where possible.
6.
Deteriorated architectural features shall be repaired rather than replaced, wherever possible. In the event replacement is necessary, the new material should reflect 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 historical, 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 materials 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 environment.
10.
Whenever possible, new additions or alterations to buildings, structures, objects, or sites 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 building, structure, object, or site would be unimpaired.
11.
In considering an application for a certificate of appropriateness, the HPO and the HPB shall review it for compliance with the secretary of the interior's standards for rehabilitation and any design guidelines previously ratified by the city council. The design guidelines shall apply in all zones within the city bearing the suffix "H".
B.
The HPB shall utilize a checklist of design elements to be reviewed and considered by the HPB in reaching its determination.
