The maintenance of any historical structure or site shall in no way involve any direct physical change except for the general cleaning and <br />upkeep of the landmark. The Commission shall encourage the proper maintenance of all structure or sites (appendix A: Minimum Maintenance <br />Standards). <br />B. Treatment <br />Treatment shall be defined as any change of surface materials that will not alter the style or original form. Such improvements include <br />re-roofing, glazing, or landscaping lawns and may involve a change that can potentially enhance or detract from the character of the <br />landmark. A treatment change of any surface whether on the landmark or in its environment may require a Certificate of <br />Appropriateness if it significantly alters the appearance of the landmark. Although these kinds of changes may not require a Building <br />Permit, a Certificate of Appropriateness may be necessary. The commission should review the proposed treatment for character and <br />style consistency with the original surfaces. <br />C. Renovation and Additions <br />Renovation is the modification of a structure, which does not alter the general massing while an addition, is a change in mass. A <br />modification, which involves the removal of a part of the landmark, should be considered under demolition (see demolition). <br /> <br />Additions to landmarks should not detract from the original form and unity of the landmark and should not cover singular examples of <br />architectural detail. Additions to landmarks should be added in a manner that does not disrupt the visible unity of overall appearance <br />of the site. The proportions, materials and ratios of the existing structures should be carried through in the additions. Care should be <br />taken not to change or alter the following: <br /> 1. Structure—–Necessary structural improvements, where safety demands should be accomplished in such a way as to cause <br />minimal visual change to the original style and construction. <br /> <br /> 2. Material—Additions and improvements involving any new material in the landmark should be of the same material as the <br />original. It should be the same size and texture. An alternative material may be 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 additional siding. <br />Structures already sided with incompatible materials should be returned to a siding similar to the original when renovation is <br />considered. <br />D. Demolition <br />Historic landmarks shall not be demolished. When a landmark poses a threat to the public safety, and demolition is the only alternative, <br />documentation by way of photographs, measured drawings, or other descriptive methods should be made of both the exterior and interior of the <br />landmark. The person or agency responsible for demolition of 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, the owner of the <br />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-graphics will also be disallowed. <br />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 /> <br />1. Required <br />Major landscaping items, trees, fencing, walkways, private yard lights, signs (house numbers) and benches which reflect the property’s history <br />and development shall be retained. Dominant land contours shall be retained. Structures such as: gazebos, patio decks, fixed barbecue pits, <br />swimming pools, tennis courts, green houses, new walls, fountains, fixed garden furniture, trellises, and other similar structures shall be <br />compatible to the historic character of the site and neighborhood and inconspicuous when viewed from a public way. <br /> <br />2. Recommended <br />New site work should be based upon actual knowledge of the past appearance of the property found in photographs, drawings, and newspapers. <br />Plant materials and trees in close proximity to the building that are causing deterioration to the buildings historic fabric should be removed. <br />However, trees and plant materials that must be removed should be immediately replaced by suitable flora. Front yard areas should not be <br />fenced except in cases where historic documentation would indicate such fencing appropriate. Fencing should be in character with the <br />buildings style, materials, and scale. <br /> <br />3. Prohibited <br />No changes may be made to the appearance of the site by removing major landscaping items, trees, fencing, walkways, outbuildings, and other <br />elements before evaluating their importance to the property’s history and development. Front yard areas shall not be transformed into parking <br />lots nor paved nor blacktopped. The installation of unsightly devices such as TV reception dishes and solar collectors shall not be permitted in <br />areas where they can be viewed from public thoroughfares. <br /> <br />Appendix A: <br />Minimum Maintenance Standards <br /> <br />All landmarks and all contributing structures located in an historic district shall be preserved from decay and deterioration, and shall be <br />maintained in good repair and kept structurally sound. The owner or other person having charge or control of landmarks and property in an <br />historic district shall not allow or permit deterioration of such property from defects or conditions which in the judgment of the Commission <br />produce a detrimental effect on the character of the district as a whole or the life and character of the landmark, structure or property in question, <br />including but not limited to: <br />
