Cultural Resources Survey for the Sun River Bridge Replacement Project C-1

Inadvertent Discovery Plan

1. If suspected archaeological material is observed, the Construction supervisor will halt work in the vicinity of the objects. No new ground disturbance should be carried out within 100 ft of the find.

Archaeological material may include objects, foundations, wells, privies that are more than 50 years old; stone, bone, wood, or antler tools or artifacts;

deposits of midden sediments; clusters of fire-modified rock, charcoal, or other evidence of fire-related activities; and faunal remains in association with stone chips or tools.

2. The Construction supervisor will secure and protect the find from damage or removal.

3. The Construction supervisor will notify the FHWA archaeologist. The FHWA archaeologist will notify the land manager and the State Historic Preservation Office (SHPO).

5. If the archaeologist determines the find is not archaeological in nature, work can resume. If the archaeologist confirms the find is archaeological, they will provide information about it to the FHWA and the SHPO. The appropriate course of action will be determined through consultation with the SHPO and appropriate Tribal Governments.
