Map Viewing Service (WMS) of the dataset: PPRNP Restricted Area Perrier Land Movement (63DDT20140006) Approved 18-07-2014 — Puy-de-Dôme

For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Within the framework of this RPP, 5 zones are defined: — a red zone (R): urbanised area exposed to severe or medium hazard for gravitary terrain movements*, — a blue zone (B): little or no urbanised area exposed to a severe, medium or low hazard for gravitary terrain movements*, — a yellow zone (J): low-level urbanised area for gravitary terrain movements* and a high degree of differential terrain movement — a grey area (Gr): area subject to a very low to zero hazard of gravitary terrain movements*, and an average hazard of differential terrain movement, regardless of space occupancy, — the cave sector In each of these areas, prohibitions and authorisations are defined under conditions.
