For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Depending on the level of hazard and the issues, each area is subject to an enforceable regulation that sets out, in a clear and operational manner, the regulatory measures that apply to each of the restricted areas. The Regulation generally distinguishes five types of zones: 1. ‘Building prohibited areas’, referred to as ‘red areas’ or ‘pink areas’, depending on the level of hazard, in an area with little or no construction, or in an agricultural or natural area, then the general rule is the prohibition on construction; 2. “areas subject to requirements”, called “magentas zones” or “blue zones”, depending on the level of hazard in a built area, then the projects are subject to requirements adapted to the type of issue; 3. “white areas” not defined in the Regulation and for which the RPIP does not apply, as they are not subject to hazard. The identification of these homogeneous areas results in the development of a mapping of the regulatory zoning of the PPRi.针对自然型PPR，《环境法典》第L562-1条将区域划分为两类：风险暴露区域，以及非直接面临风险但可采取措施规避风险加剧的区域。 根据危害等级与相关问题，每类区域均需遵循一项强制性法规，该法规以清晰且可操作的方式明确适用于各管制区域的监管措施。该法规通常将区域划分为五类： 1. "禁止建设区域"：依据危害等级不同，又可称为"红色区域"或"粉色区域"。若区域内建设活动极少或无建设，或属于农业或自然区域，则通用规则为禁止建设； 2. "需符合要求的区域"：依据危害等级不同，又可称为"品红色区域"或"蓝色区域"。若区域为建成区，则相关项目需遵循适配问题类型的要求； 3. "白色区域"：法规未对其作出定义，且RPIP不适用于此类区域，因其不受风险影响。 对这些均质区域的识别工作，将推动PPRi监管分区地图的编制。
