New Aquitaine partial: Restricted zones from PPRN Flooding (surfacic-threshold rating)

This dataset contains the restricted zones — threshold rating (surface objects) of PPRN Flooding of the Nouvelle-Aquitaine region, where GIS data exist. NOTE: this dataset is not exhaustive on the Nouvelle-Aquitaine region. 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 on which measures can be foreseen to avoid d’#x27; aggravate the risk.Depending on the level of #x27; hazard, each zone is the subject of an opposable settlement. Regulations generally distinguish three types of zones: 1- ‘zones d' prohibition to build’, known as ‘red zones’, where the level of #x27; hazard is strong and the general rule is #x27; prohibition on building; 2- ‘zones subject to requirements’, known as ‘blue zones’, where the level of hazard is average and projects are subject to requirements adapted to the type of #x27; stakes; 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 (cf. Article L562-1 of the Code of the Environment). The latter category is only applicable to natural PPRs. NOTE: Detailed metadata by PPRn is available from DDT/M. Some PPRn may be in the process of revision. GIS data are provided for informational purposes and have no regulatory value. GIS data for PPRs are not exhaustive (data in production). __Origin__ The boundaries of a restricted zone are represented on the graphical documents of the PPR. Regulatory limits are generally set on natural phenomena, which do not follow cadastral or administrative boundaries. A PPRT determines the boundaries of the different restricted zones according to the calculated right-of-way of the hazardous phenomena of the site.Some PPRs may sometimes contain regulations associated with linear or punctual figures (cavities, runoff axis...). The linear and point graphics primitives are to be used in these cases respectively. __Partner organisations__ DREAL Nouvelle-Aquitaine __Links annexes__ * [COVADIS data standard: Restricted zone of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ZONE_REG_PPRN_AAAANNNN_S) * [basketDownloadFrontalParametrage](https://catalogue.sigena.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=3933889) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/1bdf53cb0dad00128ccb27c7ec633f3efa2d0328)
