Simple download service (Atom) for the dataset: PPR LESCAR (64DDTM20050021) - Hazard zone of the LESCAR Flood Risk Prevention Plan (64335), department of Pyrénées-Atlantiques.

Area exposed to one or more hazards represented on the hazard map used for the PPR risk analysis. The hazard map is the result of the hazard study whose objective is to assess the intensity of each hazard at any point in the study area. The assessment method is specific to each type of hazard. It leads to the delimitation of a set of zones on the study perimeter constituting a zoning graduated according to the level of the hazard. The assignment of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity. For multi-hazard PPRNs, each zone is usually identified on the hazard map by a code for each hazard to which it is exposed. All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) because they are always considered subject to hazard (case of rupture or insufficiency of the structure). Hazard zones can be qualified as elaborated data to the extent that they result from a synthesis using several sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards. Some areas of the study perimeter are considered "zero or insignificant hazard areas". These are the areas where hazard has been studied and where it is zero. These zones are not included in the object class and do not have to be represented as hazard zones. However, in the case of natural PPRs, regulatory zoning may classify certain non-hazardous areas as areas of prescription (see definition of ZonePPR). Tables of areas exposed to one or more hazards, represented on the PPR hazard map. Warning: The data disseminated are informative and not opposable to the third party. GIS data have been standardized from the numerical data used in the development of the approved PPRn. We do not guarantee their completeness and accuracy in relation to the opposable documents. Official documents that are opposable to third parties can be consulted at the Town Hall or the prefecture.
