STEP 4
Achieving a Resolution

The agency and consulting parties work to reach agreement on a resolution.

In the final step of the process, the agency explores measures to avoid or reduce harm to historic properties and reach agreement with the State (or Tribal) Historic Preservation Officer (and the ACHP in some cases) on measures to resolve any adverse effects.

Determination

Were the parties able to agree on a solution?
Yes
A resolution was achieved.
A Memorandum of Agreement (MOA) or Programmatic Agreement (PA), which are records of the agreed upon resolution measures to resolve adverse effects, is drafted, signed, and executed prior to approval of the project.
No
The parties were unable to reach agreement.
The federal agency must obtain formal advisory comments from the ACHP, which are sent to the head of the agency, who must consider them in making a final decision about whether the project will proceed.
