The Commission has the authority to determine the architectural merits and the extent of any proposed treatment,renovation,or <br /> addition to a historic landmark. The commission will require drawings,plans,specifications,and/or samples where appropriate. <br /> A. Maintenance <br /> The maintenance of any historical structure or site shall in no way involve any direct physical change except for the <br /> general cleaning and upkeep of the landmark. The Commission shall encourage the proper maintenance of all <br /> structure or sites. <br /> B.Treatment <br /> Treatment shall be defined as any change of surface materials that will not alter the style or original form. <br /> Such improvements include re-roofing,glazing,or landscaping lawns and may involve a change that can <br /> potentially enhance or detract from the character of the landmark. A treatment change of any surface <br /> whether on the landmark or in its environment may require a Certificate of Appropriateness if it significantly <br /> alters the appearance of the landmark. Although these kinds of changes may not require a Building Permit,a <br /> Certificate of Appropriateness may be necessary. The commission should review the proposed treatment for <br /> character and 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 <br /> change in mass. A modification,which involves the removal of a part of the landmark,should be considered under <br /> demolition(see demolition). <br /> Additions to landmarks should not detract from the original form and unity of the landmark and should not cover <br /> singular examples of architectural detail. Additions to landmarks should be added in a manner that does not disrupt <br /> the visible unity of overall appearance of the site. The proportions,materials and ratios of the existing structures <br /> should be carried through in the additions. Care should be taken not to change or alter the following: <br /> I.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 <br /> the 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 <br /> with additional siding.Structures already sided with incompatible materials should be returned to <br /> a siding 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 should <br /> be made of both the exterior and interior of the landmark. The person or agency responsible for demolition of the <br /> 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 <br /> necessary,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-graphics <br /> will also be disallowed. Only one appropriate identifying sign will be permitted per business. <br /> G.Building Site and Landscaping(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. Dominant land contours shall be retained. Structures <br /> such as:gazebos,patio decks,fixed barbecue pits,swimming pools,tennis courts,green houses,new walls,fountains, <br /> fixed garden furniture,trellises,and other similar structures shall be compatible to the historic character of the site and <br /> neighborhood and inconspicuous when viewed from a public way. <br /> 2.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. Fencing should be in character with the buildings style, <br /> materials,and scale. <br /> 3.Prohibited <br /> No changes may be made to the appearance of the site by removing major landscaping items,trees,fencing, <br /> walkways,outbuildings,and other elements before evaluating their importance to the property's history and <br /> development. Front yard areas shall not be transformed into parking lots nor paved nor blacktopped. The installation <br /> of unsightly devices such as TV reception dishes and solar collectors shall not be permitted in areas where they can be <br /> viewed from public thoroughfares. <br />
