The United States Army Corps of Engineers Tribal Nations Technical Center of Expertise (TNTCX) was established in order to provide a cost-effective administrative tool to improve USACE’s quality and effectiveness in delivering USACE missions and Federal Trust responsibilities to Federally recognized tribes. In that role, the TNTCX can engage with each of the 574 Federally recognized Native American Tribes, national and regional organizations representing Native American governments, Native American communities, and the USACE Commands serving those communities. The TNTCX program is vital to the successful management of our relationships with Tribal Nations, which helps us maintain and operate key infrastructure projects that contribute to the Nation’s economy, environment, safety, and quality of life - now and in the future.



Alliance for Engineering Resilient Indigenous Infrastructure (AERII)

Meeting participants included representatives from the University of Alabama, the Alabama Water Institute, the University of New Mexico, Mississippi State University, the University of Georgia, and the Georgia Institute of Technology.Inter-University Research Partnership Meeting

PURPOSE:  To leverage expertise across a variety of institutions and organizations to deliver the most innovative proof of concept solutions to Indigenous communities on topics related to Technology, Infrastructure, and Culture.

NEED:  Indigenous communities across the United States are in dire need of culturally tailored engineering solutions to resolve a host of infrastructure challenges.  These needs are further complicated by the historical disconnect between western approaches to delivering these services and Indigenous perspectives on how solutions should be constructed.  The aim of the alliance is to provide an agile and capable team to outreach and deliver best science, innovation, and culturally sensitive proof of concept projects that support Indigenous culture and sovereignty. 

SUMMARY: On March 3rd, 2022, the USACE Tribal Nations Technical Center of Expertise hosted an inter-university research partnership meeting to align University and Federal research and technical services with the upcoming infrastructure work in Indian Country. Meeting participants included representatives from the University of Alabama, the Alabama Water Institute, the University of New Mexico, Mississippi State University, the University of Georgia, and the Georgia Institute of Technology. Attendees discussed their institution’s research capabilities and resources, upcoming infrastructure work, and next steps toward collaboration. Attendees resolved to develop an alliance for the creation of resilient Indigenous infrastructure.

Tribal Treaties Database

The Tribal Treaties database is an initiative supported by the White House Council on Native American Affairs. It includes agreements between tribal nations and the United States (1778-1886) published in the 1904 work “Indian Affairs: Laws and Treaties” (Volume II), compiled and edited by Charles J. Kappler.

This is a beta test site, the database will continue to evolve into early 2022 as connections are built  with present-day tribes.
