Commonly Asked Questions about Section 106 and the State Register Act
What is "Section 106" review?
Section 106 of the National Historic Preservation Act requires Federal agencies to take historic properties into account in all projects in which agencies are involved. The Act requires agencies to initiate consultation not only with the state historic preservation officer [SHPO] but also with tribal representatives, local groups and governmental entities. In its simplest form, an agency is required to identify and evaluate the National Register eligibility of cultural resources within the area affected by a project; determine how a project will affect eligible or listed properties; and seek alternatives to avoid, minimize and mitigate effects to such properties. The role of the SHPO is to advise and comment upon an agency’s determinations at each stage of this process. The SHPO does not have the authority to stop a project, but it is entitled to obtain from agencies sufficient information upon which to comment.

The SHPO has a maximum of 30 calendar days to respond to most types of reviews. However, staff endeavors to respond within two weeks.
Four OAHP staff spend most or part of their time reviewing between 2000 and 3000 projects a year in consultation with staff archaeologists, historians and architectural historians. Projects range from U.S. Army Corps of Engineers 404 permit file searches to cultural resource survey reports with inventory forms, architectural drawings to NEPA (National Environmental Policy Act) documents, cultural resource management plans to regulations revisions and one-page project descriptions to complex multiparty agreements.
Prevent someone from demolishing a historic building?
We will need the following information in order to provide you with the most accurate advice:
What is the name, if known, and address of the building?
How old is the building?
Is there federal or state agency involvement?
Is the building locally landmarked?
The State Register of Historic Places Act or a local landmark ordinance may provide some level of historic property protection or consideration when there is no federal involvement.
