D.C. Mun. Regs. tit. 10, r. 10-C501
For properties designated solely or in part for their archaeological significance, the Board and staff shall determine the effect of the proposed work on the designated archaeological features, and shall recommend an appropriate treatment consistent with the Guidelines for Archaeological Investigations in the District of Columbia ("Archaeological Guidelines"), as prepared by the staff.
Upon receipt of a permit or conceptual review application affecting a property designated for archaeological significance, the staff shall determine in consultation with the applicant if the proposed work is likely to affect any archaeological site on the property. The staff shall consult with the applicant with the objective of reaching agreement on an appropriate treatment for the affected archaeological site, consistent with the Archaeological Guidelines.
Dependent on the circumstances, appropriate treatments may include avoiding disturbance of the site, archaeological testing, or excavation and recovery of artifacts and data. If the staff and applicant reach agreement, the staff may approve work covered by the delegation of authority in Chapter 3.
The staff shall determine whether review by the Board is appropriate, depending on the significance of the property and the circumstances of the case. If the staff and applicant are unable to reach agreement on a scope of work, the staff shall refer the case to the Board for consideration in accordance with the procedures in Chapter 3.
The Board may recommend that an archaeological site not be disturbed, or if disturbance is unavoidable, may recommend that the Mayor's Agent require the applicant to undertake investigation of the features in a manner consistent with the Archaeological Guidelines.
The Mayor's Agent may impose specific conditions or requirements for archaeological investigation as appropriate.
