(A) Conforms to the city’s Historic District Streetscape Plan or Main Street architectural drawings;
(B) Conforms to the Secretary of Interiors Standards for Rehabilitation as follows:
(1) A property shall be used for its historic purpose or be placed in a new use that requires minimal change to the defining characteristics of the building and its site and environment;
(2) The historic character of a property shall be retained and preserved. Removal of historic materials or alteration of features and spaces that characterize a property shall be avoided;
(3) Each property shall be recognized as a physical record of its time, place and use changes that create a false sense of historical development, such as adding conjectural features or architectural elements from other buildings, shall not be undertaken;
(4) Most properties change over time; those changes that have acquired historic significance in their own right shall be retained and preserved;
(5) Distinctive features, finishes and construction techniques or examples of craftsmanship that characterize a historic property shall be preserved;
(6) Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture and other visual qualities and, where possible, materials. Replacement of missing features shall be substantiated by documentary, physical or pictorial evidence;
(7) Chemical or physical treatments, such a sandblasting, that cause damage to historic materials shall not be used. The surface cleaning of structures, if appropriate, shall be undertaken using the gentlest means possible;
(8) Significant archeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigation measures shall be undertaken;
(9) New additions, exterior alterations or related new construction shall not destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale and architectural features to protect the historic integrity of the property and its environment; and
(10) New additions and adjacent or related new construction shall be undertaken in such a manner that, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired.
(C) NPS Technical Bulletins, Keeping Up Appearances and other technical references;
(D) Alterations to an existing, contributing historic building, site structure or object located in a zoned historic district shall properly preserve the historical and architectural characteristics which make it unique, and any changes or additions shall conform to the intrinsic and unique character of the building or structure itself;
(E) The design should adhere to the Secretary of the Interior’s Standards for Rehabilitation and the owner or developer should be aware of current tax incentives when rehabilitation work is contemplated; and
(F) New construction within a Historic Preservation Zoning District shall require no specific architectural style; however, the following criteria should be considered in determining whether the proposed design of a new structure is compatible with the collective characteristics of the structures located within the Historic Preservation Zoning District.
(1) Height. Alterations to a zoned historic building may be no higher than the tallest comparable feature of the existing structure or adjacent structures.
(2) Setback. Alterations to a zoned historic building must maintain the original front setback of the existing structure or the prevailing setback existing within the Historic District; providing that, such a setback is compatible with the historic character of the existing building.
(3) Proportion. Alterations to a zoned historic building shall reflect the proportions of the existing building or can be demonstrated to be historically accurate.
(4) Roof types. Alterations to a zoned historic building shall have roofs compatible in configuration, mass and materials to that of the style of the existing building or can be demonstrated to be historically accurate.
(5) Texture. Surface texture of alterations to a zoned historic building shall be appropriate to the historical style of the existing building and the period in which it was constructed or can be demonstrated to be historically accurate.
(6) Site utilization. Site utilization shall be compatible with the historical period in which the existing building was built.
(7) Projections and recessions. Projections and recessions, such as porches, steps, awnings, overhangs, entrances, windows and the like, shall be compatible with the style of the existing building and/or the historical period in which it was built.
(8) Architectural details.
(a) Architectural details, such as cornices, lintels, arches, grill work, shutters, window and door trim canals and the like, shall be appropriate to the historical style of the existing building and/or the historical period in which it was built.
(b) An exception, for case by case review, will be grill work for security.
(9) Building form. Size, mass and scale of alteration to a designated historic building shall be compatible with that of the existing building or it can be demonstrated to be historically accurate.
(10) Color. Color of a building, including trim, roof and the like, shall be appropriate to the architectural style of the subject building and/or its historical period.
(11) Landscaping. Planting and other ornamental features shall reflect the historical period of the subject structure.
(12) Enclosures. Fences, walls or other physical features used to enclose open space or provide privacy shall be based on historic precedent or shall be compatible with the architectural style of the subject building and compatible with other historic buildings within the Historic Preservation Zoning District and reflect the historical period of the Historic Preservation Zoning District.
(13) Utilities. New power, telephone and cable television installation shall be reviewed for appropriateness and compatibility. No electric utility boxes shall be used on street side facades if any alternative location is feasible. Solar units and TV antennae dishes shall not be visible from the street level.
(14) Alterations. Alterations to a non-historic building within a historic district shall reflect the architectural style and characteristics of the existing building. In addition, such alterations shall generally conform to the above criteria of the buildings within the Historic District.
