APPENDIX B:
Secretary of the Interior's Standards


The Secretary of the Interior's Standards for Preservation are:

  1. A property will be used as it was historically, or be given a new use that maximizes the retention of distinctive materials, features, spaces, and spatial relationships. Where a treatment and use have not been identified, a property will be protected and, if necessary, stabilized until additional work may be undertaken.

  2. The historic character of a property will be retained and preserved. The replacement of intact or repairable historic materials or alteration of features, spaces, and spatial relationships that characterize a property will be avoided.

  3. Each property will be recognized as a physical record of its time, place, and use. Work needed to stabilize, consolidate, and conserve historic materials and features will by physically and visually compatible, identifiable upon close inspection, and properly documented for future research.

  4. Changes to a historic structure that have acquired historic significance in their own right will be retained and preserved.

  5. Distinctive materials, features, finishes, and construction techniques or examples of craftsman ship that characterize a property will be preserved.

  6. The existing condition of historic features will be evaluated to determine the appropriate level of intervention needed. Where the severity of deterioration requires repair or limited replacement of a distinctive feature, the new material will match the old in composition, design, color, and texture.

  7. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used. Archeological resources will be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken.

The Secretary of the Interior's Standards for Restoration are:

  1. A property will be used as it was historically or be given a new use which reflects the property's restoration period.

  2. Materials and features from the restoration period will be retained and preserved. The removal of materials or alteration of features, spaces, and spatial relationships that characterize the period will not be undertaken.

  3. Each property will be 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 be physically and visually compatible, identifiable upon close inspection, and properly documented for future research. Materials, features, spaces and finishes that characterize other historical periods will be documented prior to their alteration or removal.

  4. Materials, features, spaces, and finishes that characterize other historical periods will be documented prior to their alteration or removal.

  5. Distinctive materials, features, finishes, and construction techniques or examples of craftsman ship that characterize the restoration period will be preserved.

  6. Deteriorated features from the restoration period will be 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.

  7. Replacement of missing features from the restoration period will be substantiated by documentary and physical evidence. A false sense of history will not be created by adding conjectural features, features from other properties, or by combining features that never existed together historically.

  8. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible. Treatments that cause damage to historic materials will not be used.

  9. Archeological resources affected by a project will be protected and preserved in place. If such resources must be disturbed, mitigation measures will be undertaken.

  10. Designs that were never executed historically will not be constructed.
