List of Natural Risk Prevention Plans digitised in 2019 in Auvergne Rhône-Alpes

Annual consolidation December 2018. Risk Prevention Plans (RPPs) are the key tool of the state for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a series of geographical data organised into several datasets. The same PPR may include spatial datasets containing: — main perimeters encompassing the PPR; — restricted areas of the plan once approved. RPP regulations generally distinguish between “building prohibition zones”, so-called “red zones”, where the hazard level is strong and the general rule is the prohibition on construction; “prescription zones”, known as “blue zones” where the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions; — hazard zones shown on the hazard map used for the risk analysis by crossing the stakes, specifying for each zone the level of hazards to which it is exposed; — stakes which are persons, property, activities and elements of cultural or environmental heritage threatened by a hazard and likely to be affected or damaged by it; — origins of risk, i.e. the entity of the real world which, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object locating the actual entity causing the risk. Each element in the same PPRN dataset is bound by the GASPAR ID format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and order number of the PPR procedure associated in GASPAR) to a single object in the PPRN document table described by the metadata sheet N_DOCUMENT_PPRN.
