STEP 3
Assessing Effects

The federal agency determines if historic properties may be adversely affected.

The federal agency determines how historic properties might be affected by the project and whether any of those effects would be considered adverse in consultation with other participants in the review. “Adverse effects” are those that diminish characteristics qualifying a property for inclusion in the National Register.

If there are no potential adverse effects on a historic property, the review may conclude here.

Determination

Are there any adverse effects on an historic property?
Yes
One or more historic properties could be adversely affected.
A finding of adverse effects requires further consultation on ways to resolve them.
No
No historic properties will be adversely affected.
The federal agency documents its finding, shares it with all consulting parties, and makes information available to the public.
The Section 106 process concludes.
