Work, including preliminary measuresto protect and stabilize the property, generallyfocuses upon the ongoing maintenance and repair oihistoric materials and features ratherthan extensive replacement and new construction. New exterior additions are not within the scope oithistreatment; however the limdetl and sensitive upgrading oimechanical, electrical, and plumbing systems and other code-required work to make propertiesfunctional is appropriate within a presen~ation project. 7. A property will 6e used as it was historically, or 6e given a new use that maximizes the retention of distinctive materials, features, spaces, and spatial relalivnships. Where a treatment and use have not been identified, a propertywill 6e protected and, if necessary, stabilized until additional work may 6e undertaken. 2. The historic character of a property will 6e retained and preserved. The replacement of intact or repairable historic materials or alteration offeatures, spaces, and spatial relationships that characterize a property will 6e avoided. 3. Each propertywill be recognized as a physical record of Rs time, place, and use. Work needed to stabilize, consolidate, and conserve existing historic materials and features will 6e physically and visually compatible, identifiable upon close inspection, and properly documented for future research. 4. Changes tv a property that have acquired historic significance in their own right will 6e retained and preserved. 5. Distinctive materials, features, finishes, and construction techniques or examples vi craftsmanship that characterize a property will 6e preserved. 6. The existing condition of historic Features will 6e evaluated to determine the appropriate level of intervention needed. Where the severity of deterioration requires repair yr limited replacement of a distinctive Feature, the new material will match the old in composition, design, color, and texture. 7. Chemical or physical treatments, fi appropriate, will 6e undertaken using the gentlest means possible. Treatments that cause damage to histaric materials vuill not be used. S. Archeological resources will 6e protected and preserved in place. If such resources must 6e disturbed, mitigation measures will 6e undertaken.

A property will be used as it was historically or be given a new use that requires minimal change to its distinctive materials, features, spaces, and spatial relationships. 2. The historic character of a property will be retained and preserved. The removal of distinctive materials or alteration of features, spaces, and spatial relationships that characterize a property will be avoided. 3. Each property will 6e 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 elements from ether historic properties, will net 6e undertaken. 4. Changes to a property that have acquired historic significance in their own right will be retained and preserved. 5. Distinctive materials, features, fin fishes, and construction techniques or examples of craftsmanship that characterize a property will 6e preserved. 6. Deteriorated historic features will 6e repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. Replacement of missing features will 6e substantiated by documentary and physical evidence. 7. Chemical or physical treatments, fi appropriate, will 6e undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not 6e used. S. Archeological resources will 6e protected and preserved in place.lfsuch resources must 6e disturbed, mitigation measures will 6e undertaken. 9. New additions, exterior alterations, yr related new cvnstructivn will net destroy historic materials, features, and spatial relationships that characterize the property. The newwork shall 6e differentiated from the old and will be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment. 10. New additions and adjacent yr related new construction will 6e undertaken in a such a mannerthat, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired.

The limited and sensitive upgrading of mechanical, electrical, and plumbing sys[ems and other code- requiretl work to make propertiesfunctional is appropriate within a restoration project. 7. A property will 6e used as it was historically yr 6e given a new use which reflects the property's restoration period. 2. Materials and features from the restoration period will 6e retained and preserved. The removal of materials or alteration of features, spaces, and spatial relationships that characterize the period will not 6e undertaken. 3. Each property will 6e recognized as a physical record of its time, place, and use. Work needed to stabilize, consolidate and conserve materials and features from the restoration period will 6e physically and visually compatible, identifiable upon close inspection, and properly documented for future research. 4.

Distinctive materials, features,finishes, and construction techniques or examples of craftsmanship that characterize the restaration period will be preserved. 6. Deteriorated features from the restoration period will 6e repaired rather than replaced. Where the severity of deteriaration requires replacement of a distinctive feature, the new feature will match the old in design, color, texture, and, where possible, materials. 7. Replacement of missing features from the restoration period will 6e substantiated 6y documentary and physical evidence. A false sense of history will not 6e created 6y adding conjectural features, features from other properties, or by combining features that never existed together historically. 8.

Reconstruction will 6e used to depict vanished or non-surviving portions of a property when documentary antl physical evidence 6 available to permit accurate reconstruction with minimal conjecture, and such reconstruction is essential to the public understanding of the property. 2. Reconstruction of a lantlscape, builtling, structure, or object in ds historic location will be preceded 6y a thorough archeological investigation to identify and evaluate those features and artifacts which are essential to an aceurate reconstruction. If such resources must be disturbed, mitigation measures will be undertaken. 3. Reconstruction will include measures to preserve any remaining historic materials, features, and spatial relationships. 4. Reconstruction will 6e based on the accurate duplication of historic features and elements substantiated 6y documentary yr physical evidence rather than vn conjectural designs yr the availability of different features from other historic properties. A reconstructed property will re• create the appearance of the non-surviving historic property in materials, design, color, and texture. 5.
