Federal and state laws mandate that all projects be evaluated for their effects on cultural resources.
Determine the type of review needed
If your project:
- Has the Federal Highway Administration (FHWA) as the lead federal agency – You must comply with Section 106. See our Section 106 Process Flowchart (PDF 147KB) for an overview of the process.
- Has a different federal lead agency or is on tribal lands – You must comply with Section 106. Contact your Cultural Resource Specialist (CRS) for more details.
- Has no federal nexus - You are required to comply with the Governor’s Executive Order 21-02 (GEO 21-02). Review the GEO 05-05 Process Flowchart (PDF 57KB) for a general overview of this process.
- Is exempt from review per the stipulations of the Programmatic agreement (PDF 699KB) – Contact your CRS.
The CRS will define the project’s Area of Potential Effect (APE), initiate consultation with interested and affected parties, and identify resources in the project area.
Check the inventory of historic state highways and bridges in Washington state to see if there are any bridges recommended, nominated, determined eligible or listed on the National Register of Historic Places (NRHP) in the project area.
If your project affects a federal interstate highway bridge included in one or more of the following lists, maintained by the FHWA, your CRS must include the bridge in the Section 106 evaluation:
- Bridges listed on the List of Nationally and Exceptionally Significant Features of the Federal Interstate Highway System are not exempt from Section 106.
- The Common Post-1945 Concrete and Steel Bridges in Washington list identifies bridges of exceptional quality that are not exempt from Section 106.
