Restricted areas of the plan for the prevention of natural hazards of the municipality of PERLES-ET-CASTELET

The regulated zoning of the Natural Hazards Prevention Plan (NRPP) is digitised in accordance with the national requirements of COVADIS. 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__ The perimeter of a prescribed PPR is usually provided in the prefect’s prescription order. The perimeter d' exposure to risks — or regulated perimeter — corresponds to the \#x27; geometric aggregation of l' all the restricted zones listed in the same PPR. The perimeter of the study corresponds to the envelope in which the hazards were studied. __Partner organisations__ DDT Ariège __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-c0ee630b-b761-4caf-b58d-79909089f8a3) * [COVADIS data standard: Restricted zone of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ZONE_REG_PPRN_AAAANNNN_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/aecb22f56898c54293bf641a3c398e0cfa74f47d)
