Preventive archaeology consists of detecting and safeguarding elements of the archaeological heritage affected or likely to be affected and destroyed by public or private development works. Archaeological remains are relatively well protected as long as they remain buried in the ground and for the vast majority of them there is no information, either by texts, ancient or recent iconography (maps, plans, aerial photographs, etc.). The facilities concerned by preventive archaeology These are constructions or works, the location of which is located on an area known for its “archaeological sensitivity”: - concerted development areas (zac) and subdivisions with an area exceeding 3 hectares - works subject to declaration or authorisation under the Urban Planning Code - developments and works subject to impact assessment (roads, quarries...) - works on buildings classified as historical monuments. The regional prefect — by delegation from the Regional Archaeology Service (SRA) within the Regional Directorates for Cultural Affairs (DRAC) — may issue a diagnostic prescription outside these areas if he has information indicating that a project is likely to affect elements of the archaeological heritage. Diagnostic prescription is not systematic.
