TDAT v2.2 was developed by the Office of Environment and Energy (OEE) to help users identify tribes that may have an interest in the location of a HUD-assisted project, and provide tribal contact information to assist users with initiating Section 106 consultation under the National Historic Preservation Act (54 U.S.C. § 300101 et seq.)

Two key aspects of TDAT are its ability to:

  1. Link tribes' geographic areas of current and ancestral interest down to the county level, and
  2. Perform a variety of queries related to tribes.

State reports link tribes to their counties of interest in the particular state. Tribes may reside in or outside of that state. Check back frequently for updates.
