Dataset description

For natural PPRs, the code of l'environment defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures may be planned to avoid d’#x27; exacerbate the risk. Depending on the level of d'aira, each zone is the subject of an opposable regulation. Regulations generally distinguish three types of zones: 1- “zones d' prohibition to build”, so-called “red zones”, when the level of #x27; hazard is strong and the general rule is #x27; prohibition to build; 2- “prescription zones”, so-called “blue zones”, where the level of #x27; hazard is average and projects are subject to requirements adapted to the type of #x27; 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 Code of the Environment). The latter category is only applicable to natural PPRs. __Origin__ Background on provenance: the perimeter of a prescribed PPR is usually provided in the prefect’s prescription order. The perimeter d' exposure to risks corresponds to the perimeter regulated by the approved PPR and also corresponds to the envelope in which the hazards have been studied. __Partner organisations__ DDT Ain __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.datara.gouv.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=52455) * [direct download of data](https://catalogue.datara.gouv.fr/rss/atomfeed/atomdataset/e5d09b42-a932-45d8-9d4f-2464d3747827) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/c9366ba72941b8225d674fa123d0061a88e1bf1b)
