HPT Portal Access

The Historic Preservation Team (HPT) Portal is a web-based research database for the storage and retrieval of electronic project data on cultural resources along ADOT right of way, excluding those on tribal lands. This documentation facilitates appropriate consideration of project-associated impacts and subsequent mitigation measures. Access to the HPT Portal is limited to qualified cultural resources professionals and is gained through application and verification of qualifications. The four application forms are available below; get more information and/or return forms to Shearon Vaughn at SVaughn@azdot.gov.

Report Reviewing Checklist

The Report Reviewing Checklist is used to ensure the adequacy of cultural resource reports submitted to HPT. The Checklist is a compilation of the Arizona State Museum's Reporting Standards, the Arizona State Historic Preservation Administrative Procedures, and the Guidelines for Report Production Standards for ADOT Consultants.
