To assist entities tasked with coordinating project review, the Texas Historical Commission (THC) has developed guidance and agreement documents for compliance with Section 106 of the National Historic Preservation Act and the Antiquities Code of Texas. This material provides supplemental instructions beyond the general overview in the Consultation Process portion of our website, and in the case of agreement documents, streamlines consultation for specific programs and agencies. For general updates regarding our project review procedures, please see How the THC Reviews Projects. To download the updated Request for SHPO Consultation form, please see What to Send for a Project Review.
