Map visualisation service (WMS) of the dataset: PPR Aydius (64DDTM19970018) — Restricted area of the Aydius Flood Risk Prevention Plan (64085), Department of Pyrénées-Atlantiques.

For natural PPRs, the environmental code defines two categories of zones (L562-1): — risk-exposed areas, — areas which are not directly exposed to the risks but on which measures may be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. Regulations generally distinguish three types of zones: 1- ‘building prohibition zones’, known as ‘red zones’, where the hazard level is high and the general rule is the prohibition on building; 2- ‘zones subject to requirements’, known as ‘blue zones’, where the hazard level is average and projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, structures, development or agricultural, forestry, artisanal, commercial or industrial operations could aggravate or cause new risks, subject to prohibitions or requirements (see Article L562-1 of the Environmental Code). The latter category applies only to natural PPRs. Table containing all the restricted areas of the PPRn. Warning: The data disseminated are informative and not enforceable against the third party.
