Mitigation

Under the provisions of Sections 106 and 110b of the amended National Historic Preservation Act of 1966, federal agencies must produce documentation to Heritage Documentation Programs (HDP) standards for buildings that are listed, or are eligible for listing, in the National Register of Historic Places, to mitigate the adverse effects of federal actions such as demolition or substantial alteration. National Park Service regional offices oversee this aspect of HDP documentation, which is submitted to the Washington, D.C., office for final review and inclusion in the collections.
