1. (1) listing in the National Register of Historic Places;
2. (2) designation as a recorded Texas historic landmark or state archeological landmark;
3. (3) qualification, as determined by the commission, as an eligible property under the criteria for inclusion in the National Register of Historic Places, or for designation as a Recorded Texas Historic Landmark or a State Archeological Landmark;
4. (4) marking by an official Texas historical marker of any type, including centennial markers;
5. (5) certification by the commission to other agencies of the state as worthy of preservation;
6. (6) determination by the state archeologist or the commission that the site or resource is capable of yielding information important to the understanding of history; and
7. (7) an age of at least 50 years, unless younger and determined by the commission to be of transcendent historical or cultural importance.
