The owner is requested to consult with the Board before making any alteration. The Board shall determine if the alteration is compatible with the designation and by resolution, make a recommendation to the Council. Property owners making alterations or constructing new buildings on their property that are adjacent to registered building, landmarks, or districts are requested to consult with the Board prior to beginning construction. For this section, the term “alteration” shall mean any proposed modification to a designated historic site, structure or district, that could have an affect on the character of the historic resources relative to the criteria by which it was designated. Examples of alterations for structures may include additions, any exterior modifications, including signage to be affixed to the facade, and any interior modifications that may affect the characteristics for which the structure was designated. The Board shall make its review as per the time line in Section 17.90.050(A), Board Review, of this chapter.
A. Criteria to Review Alterations. In reviewing a proposed alteration, the Board shall consider the project in terms such as design, finish, material, scale, mass and height. When the subject site is in an historic district, the Board must also find that the proposed development is visually compatible with the development on adjacent properties, as well as any guidelines adopted as part of the given historic district designation. For this section, the term “compatible” shall mean consistent with, harmonious with and/or enhances the mixture of complementary architectural styles either of the architecture of an individual structure or the character of the surrounding structures. The Board will use the following criteria to determine compatibility of a proposed alteration:
1. The effect upon the general historical and architectural character of the structure and property;
2. The architectural style, arrangement, texture and material used on the existing and proposed structures and their relation and compatibility with other structures;
3. The size of the structure, its setbacks, its site, location and the appropriateness thereof, when compared to existing structure and the site;
4. The compatibility of accessory structures and fences with the main structure on the site, and with other structures;
5. The effects of the proposed work in creating, changing, destroying, or otherwise impacting the exterior architectural features of the structure upon which such work is done;
6. The condition of existing improvements and whether they are a hazard to public health and safety; or
7. The effects of the proposed work upon the protection, enhancement, perpetuation and use of the property.
B. Existing non-conforming single household residential uses in buildings located in the C-3 zone that have been granted historic designation as per this chapter may expand contingent upon the applicant receiving approval from both the historic preservation board as well as the Planning Commission and the City Council. Additional criteria that shall be used to determine appropriateness of the alteration(s) include:
1. The expansion shall not be greater than twenty-five percent of the total net floor area of the structure.
2. Proof that the structure was used and has continued to be used as a residence prior to the adoption of the original zoning code on December 31, 1958.
3. The addition shall be completed in a manner that will enhance and accent the historic character of the home with minimal alterations to the facade.
4. The requirements of the latest adopted revision of the building code shall be met. (Ord. 19-13 § 18, 2019; Ord. 08-11 (part), 2008)
