Zonings natural risk: Punctual issue of the PPRN of Theols

In general, the issues are people, property, activities, elements of cultural or environmental heritage, threatened by a hazard and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called "vulnerability".This class of subject brings together all the issues that were taken into account in the PPR study. An issue is a dated object whose consideration depends on the purpose of the PPR and its vulnerability to the hazards studied. A PPR issue can therefore be taken into account (or not) depending on the type or types of hazard treated. These elements constitute the basis of knowledge of land use necessary for the development of the PPR, in the study area or near it, at the date of the analysis of the issues.The data of stakes represent a photograph (figured and not exhaustive) of the goods and people exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after RPP approval. In practice, they are no longer used: issues are recalculated as needed with up-to-date data sources.
