1. Reconstruction will be used to depict vanished
or non-surviving portions of a property when documentary
and physical evidence is available to permit accurate
reconstruction with minimal conjecture, and such reconstruction
is essential to the public understanding of the property.
2. Reconstruction of a landscape, building, structure,
or object in its historic location will be preceded
by a thorough archeological investigation to identify
and evaluate those features and artifacts which are
essential to an accurate 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
4. Reconstruction will be based on the accurate
duplication of historic features and elements substantiated
by documentary or physical evidence rather than on conjectural
designs or 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. A reconstruction will be clearly identified as
a contemporary re-creation.
6. Designs that were never executed historically
will not be constructed.
