Information for County Historical Commissions

Please see this chart from the Texas Preservation Handbook for County Historical Commissions that outlines the basic steps of the marker application process (PDF).

County Historical Commission Chairs may submit to THC the Marker Chair Authorization Form (PDF) to appoint a CHC contact for all marker correspondence.

What is a marker chair? While many county historical commission (CHC) chairs personally oversee the local reviews, approvals and coordination of Official Texas Historical Marker applications, others choose to appoint a marker chair to serve in that capacity. Regardless of how your CHC is structured, the basic requirements for local review are the same. The CHC chair or marker chair (appointed by the CHC chair) serves as the sole liaison with the Texas Historical Commission (THC) throughout the marker process. See the Marker Chair Job Description (PDF) for more details.

If you need to move a marker, submit the Marker Relocation Form in Word (or PDF) to the THC.

To order a replacement for a damaged or missing marker, including replacement parts for Texas Centennial markers, use the Marker Replacement Form in Word (or PDF). To order a supplemental plaque to correct or add information (one sentence), use the Supplemental Plaque Order Form in Word ( or PDF). 

Found a mistake on a marker? Request to have the THC review a marker for a possible correction.
