They provide technical advice about archeological and historic preservation activities and methods.

"Site" means the location of a significant event, a prehistoric or historic occupation or activity, or a building or structure, whether standing, ruined, or vanished, where the location itself maintains historical or archaeological value regardless of the value of any existing structure.

"Survey" is the accepted method of systematically studying historic resources. It includes statements of significance according to the criteria set forth in this article and, when available, a physical description and a photograph of each historic resource, legal information from title or assessment records, and a statement of any potential threats to the integrity or continued existence of the resource. The information is recorded onto a survey sheet and kept as a historic resources inventory.
