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. The regulations generally distinguish between three types of zones:1- “zones d' prohibition to build”, so-called “red zones”, when the level of ' hazard is strong and the general rule is n°#x27; prohibition to build;2- “required areas”, known as “blue zones”, when the level of #x27; hazard is average and projects are subject to requirements adapted to the type of d' at stake;3- areas not directly exposed to risks but where constructions, structures, development or agricultural, forestry, artisanal, commercial or industrial operations could aggravate risks or cause new ones, subject to prohibitions or requirements (see Article L562-1 of the Code de l' environment). The latter category is only applicable to natural PPRs. __Origin__ Surface, linear or point information is shown on the graphical document of the PLU or POS.
