Restricted areas of the OUDAN River Flood Risk Prevention Plan and its AFFLUENTS — Loire

Risk Prevention Plans (RPPs) are the key instrument for risk prevention. Their objective is to control development in areas at risk. L' development of a risk prevention plan generates a series of spatial 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. PPR regulations generally distinguish between “zones d' prohibition to build”, so-called “red zones”, where the level of ' hazard is strong and the general rule is the “prohibition to build”; “prescription areas”, known as “blue zones” when the level of #x27; hazard is average and projects are subject to requirements adapted to the type of #x27; stakes and areas not directly exposed to risks but subject to prohibitions or prescriptions; — hazard zones shown on the map of hazards used in #x27; 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 real-world entity which, by its presence, represents a potential risk. This entity can be characterised by a name, a reference to an external object, or a geographical object l' real entity at the origin of the risk. The same PPRN dataset is bound by the GASPAR identifier in the format “ddd[PREF|DDT|DDTM|DREAL]aaaaaaannnn” (AAAA and NNNN corresponding to the reference year and number d' order of the PPR procedure associated in GASPAR) to a single object. __Origin__ The master responsible for managing the PPR decided to take over the file to produce the data in COVADIS format. This production may involve the resumption of pre-existing geographical data as part of digitisation. __Partner organisations__ DDT 42 (Departmental Directorate of the Loire Territories) (Departmental Directorate of the Loire Territories) __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.datara.gouv.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=19838404) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/5e18cb511f93dc2f03840404fa579d25294cea40)
