Any federal agency whose project, funding or permit may affect a historic property, both those listed or eligible for inclusion in the National Register of Historic Places, must consider the effects on historic properties and "seek ways to avoid, minimize or mitigate" any adverse effects on historic properties. The typical Section 106 Review involves four primary steps: 1 - Initiation of the Section 106 Review; 2 - Identification of Historic Properties; 3 - Assessment of Adverse Effects; and 4 - Resolution of Adverse Effects. Further steps may be required if there is a disagreement among the consulting parties on adverse effects or the resolution of the effects.
