Introduction
An Introduction to Section 106

Section 106 of the National Historic Preservation Act of 1966 (NHPA) requires federal agencies to consider the effects on historic properties of projects they carry out, assist, fund, permit, license, or approve throughout the country. If a federal or federally-assisted project has the potential to affect historic properties, the Section 106 review will take place.

Section 106 gives the ACHP, the public, and other interested parties the chance to weigh in on these matters before a final decision is made. This process is an important tool for citizens and other contributors to lend their voice in protecting and maintaining historic properties in their communities.
