About this file
This is an Archaeological Inadvertent Discovery Plan (IDP) prepared by the Oregon Department of Transportation (ODOT) for the I-5 Exit 135 to Exit 140 Selective Dead Tree Removal Project. The document establishes procedures and protocols that contractors and all associated personnel must follow during ground-disturbing activities for the removal of approximately 78 dead or visibly dying trees from ODOT right-of-way. The IDP provides comprehensive guidance on identifying potential archaeological findings, which may include precontact artifacts such as stone tools, arrowheads, and bone implements, as well as historic-era materials including nails, glass, metal cans, ceramics, and structural remains. The document emphasizes that all excavation and work must immediately cease upon discovery of archaeological material or human remains, with a mandatory 30-meter (100-foot) buffer zone established around any find while assessment and notification procedures are executed.
The discovery procedures outlined require contractors to notify the ODOT Regional Environmental Coordinator, ODOT Archaeologist, Project Manager, and lead Inspector upon encountering archaeological material. For human remains specifically, additional notifications must be made to the Oregon State Police, State Historic Preservation Office (SHPO), Legislative Commission on Indian Services (LCIS), and appropriate Native American Tribes. The document emphasizes strict confidentiality protocols in accordance with the National Historic Preservation Act and Oregon State law, prohibiting disclosure to media or the public without prior concurrence from responsible agencies and Tribes. Contact information is provided for key personnel including Terry Luecker (ODOT REC), Jessie Plueard (ODOT Archaeologist), Tobin Bottman (Archaeological Program Manager), and other state officials responsible for archaeological oversight and coordination.

DISCOVERY PROCEDURES: WHAT TO DO IF YOU FIND SOMETHING
1. Stop ALL work in the vicinity of the find
2. Secure and protect area of inadvertent discovery with 30 meter/100 foot buffer—work may continue outside of this buffer
3. Notify the Project Manager and the ODOT Regional Environmental Coordinator (REC), Archaeologist, and lead Inspector.
4. The ODOT REC or ODOT Archaeologist will contact a professional archaeologist to assess the find.
5. If the archaeologist determines the find is an archaeological site or object, the ODOT REC or
ODOT Archaeologist will contact the State Historic Preservation Office (SHPO). If it is determined to not be archaeological, you may continue work.
HUMAN REMAINS PROCEDURES
1. If it is believed the find may be human remains, stop ALL work.
2. Secure and protect area of inadvertent discovery with 30 meter/100 foot buffer, then work may continue outside of this buffer with caution.
3. Cover remains from view and protect them from damage or exposure, restrict access, and leave in place until directed otherwise. Do not take photographs. Do not speak to the media.
4. Notify the Project Manager and the ODOT REC, ODOT Archaeologist and lead Inspector. The
ODOT REC or ODOT Archaeologist will contact the Oregon State Police, SHPO, Legislative
