PPR inondation (périmètres)
What this layer shows
Perimeters of flood risk prevention plans, as published as PM1 servitudes on the Géoportail de l'urbanisme. An approved PPR is a public-interest servitude: its rules can ban building or impose conditions. Coastal (sea-flooding) PPRs appear here or in the multi-hazard layer, depending on how they are coded.

Constraints
The constraints a consultancy checks first: Natura 2000 (the basis of the impact assessment), nature reserves, biotope orders, ZNIEFFs, classified sites, historic monument surroundings and PPR flood perimeters. It does not include each PPR's detailed regulatory zoning or the PLU rules: consult the planning document for buildability.
Natural hazards
The risk prevention plan perimeters (flood, ground movement, forest fire, avalanche, marine submersion, technological and mining), the underground cavities, the recorded ground movements, the seismic zoning and the polluted-soil sectors. Each PPR's precise regulatory zoning remains in the document itself.
