PPRN Hazard Zone — BREVENNE Turdine

Area exposed to one or more hazards and depicted on the map d' hazard produced as part of the RPP; development of the PPR. The map d'random is the result of the study of hazards whose goal is to evaluate the intensity of each hazard at any point in the zone of study. The evaluation method is specific to each type of hazard. It leads to the delimitation of a set of zones on the perimeter of the constituent study a zoning graduated according to the level of l'aira. 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-random PPRNs, each zone is usually spotted on the d'aira map by a code for each hazard to which it is exposed. For PPRTs levels d'aira are determined effect by effect on maps by type of d' effects and overall according to an aggregate level on a synthesis map. __Origin__ The boundaries of a zone d'aira are represented on the map d'random according to the level of l'random. In other words, polygon objects representing zones d'random form a cover part of the studied area where each cover element is a closed polygon in which hazards have the same level of intensity. In other words, the cutting modality in zone d'random is the level of l'random. __Partner organisations__ DDT Rhône __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.datara.gouv.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=7060) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/0d5673efd211afe730ec571c7b29e617bfc4f9fc)
