A treatment changes of any surface whether on the landmark <br />or in its environment may require a Certificate of Appropriateness if it significantly alters the appearance of the <br />landmark. Although these kinds of changes may not require a Building Permit, a Certificate of Appropriateness <br />may be necessary. The commission should review the proposed treatment for character and style consistency with <br />the original surfaces. <br />C. Renovation and Additions <br />Renovation is the modification of a structure, which does not alter the general massing while and addition, is a <br />change in mass. A modification, which involves the removal of a part of the landmark, should be considered under <br />demolition (see demolition). Additions to landmarks should not detract from the original form and unity of the <br />landmark and should not cover singular examples of architectural detail. Additions to landmarks should be added in <br />a manner that does not disrupt the visible unity of overall appearance of the site. The proportions, materials and <br />ratios of the existing structures should be carried through in the additions. Care should be taken not to change or <br />alter the following: <br />1. Structure - Necessary structural improvements, where safety demands should be accomplished in such a <br />way as to cause minimal visual change to the original style and construction. <br />2. Material - Additions and improvements involving any new material in the landmark should be of the <br />same material as the original. It should be the same size and texture. An alternative material may be <br />allowed if it duplicates the original. <br />a. wood - all wood trim should conform with existing trim in shape and size. <br />b. siding materials - the Commission discourages the covering or alteration of original materials with <br />additional siding. Structures already sided with incompatible materials should be returned to a siding <br />similar to the original when renovation is considered. <br />D. Demolition <br />Historic landmarks shall not be demolished. When a landmark poses a threat to the public safety, and demolition is <br />the only alternative, documentation by way of photographs, measured drawings, or other descriptive methods <br />should make of both the exterior and interior of the landmark. The person or agency responsible for demolition of <br />the landmark shall be responsible for this documentation. <br />E. Moving <br />The moving of landmarks is discouraged, however, moving is preferred to demolition. When moving is necessary, <br />the owner of the landmark must apply to the Commission for a Certificate of Appropriateness. <br />F. Signs <br />No neon or flashing signs will be permitted unless they are original to the structure. Billboards and super - <br />graphics will also be disallowed. Only one appropriate identifying sign will be permitted per business. <br />G. Building Site and Landscaping <br />(These standards apply to both A and B) <br />1. Required <br />Major landscaping items, trees, fencing, walkways, private yard lights, signs (house numbers) and benches which <br />reflect the property's history and development shall be retained.

Recommended <br />New site work should be based upon actual knowledge of the past appearance of the property found in photographs, <br />drawings, and newspapers. Plant materials and trees in close proximity to the building that are causing deterioration <br />to the buildings historic fabric should be removed. However, trees and plant materials that must be removed should <br />be immediately replaced by suitable flora. Front yard areas should not be fenced except in cases where historic <br />documentation would indicate such fencing appropriate.
