The federal agency overseeing the project inventories the project area (or contracts with a qualified consultant) to determine the presence or absence of historic properties. They then submit to the SHPO a Determination of Effect/Finding of Effect (DOE/FOE) outlining to the SHPO the project, the efforts taken identify historic properties, and what effects, if any, the project may have on historic properties. If the project is believed to have no adverse effect on eligible historic resources and the SHPO and other consulting parties agree, then the Section 106 process is effectively closed and the project may proceed. Alternatively, if an adverse effect is expected, the agency is required to work with the local State Historic Preservation Office to ensure that all interested parties are given an opportunity to review the proposed work and provide comments. This step seeks ways for the project to avoid having an adverse effect on historic properties. Ideally, a Memorandum of Agreement is reached between all consulting parties outlining agreed to mitigation or avoidance of historic properties, but this is not always the case. Without this process historical properties would lose a significant protection. This process helps decide different approaches and solutions to the project, but does not prevent any site from demolition or alteration.
