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 hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, crafts, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.针对自然风险相关区域（natural PPRs），《环境法典》（Environmental Code）第L562-1条将其划分为两类：一是风险暴露区域，二是未直接暴露于风险但可预先制定防控措施以避免风险加剧的区域。根据危险等级的不同，每类区域均需遵守可强制执行的管控规则。 该法规通常将区域划分为三类： 1. “禁止建设区域”（亦称“红色区域”）：此类区域危险等级较高，基本原则为禁止建设； 2. “限制建设区域”（亦称“蓝色区域”）：此类区域危险等级为中等，相关项目需遵守适配问题类型的管控要求； 3. 未直接暴露于风险，但建设工程、开发项目或农业、林业、手工业、商业、工业场所等可能加剧既有风险或引发新风险的区域，需遵守禁止性规定或管控要求（参见《环境法典》第L562-1条）。 该第三类区域仅适用于自然风险相关区域（natural RPPs）。
