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 zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the 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, craft, 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.针对自然风险预防规划（PPRs），《环境法典》（L562-1条款）将其涉及的区域划分为两类：风险暴露区域，以及虽未直接面临风险，但可通过预先制定措施以避免风险加剧的区域。 依据危险等级的不同，每类区域均需遵循可强制执行的规制要求。相关法规通常将区域划分为三类： 1. 建筑禁止区（亦称"红色区域"）：该区域危险等级较高，原则上禁止一切建设活动； 2. 合规管控区（亦称"蓝色区域"）：该区域危险等级中等，建设项目需遵循适配于风险类型的专项管控要求； 3. 间接风险关联区域：该区域虽未直接暴露于风险之中，但各类建设工程、开发项目以及农业、林业、手工业、商业、工业类经营场所或农场，可能加剧既有风险或引发全新风险，需遵守禁止性规定或专项管控要求（详见《环境法典》L562-1条款）。 上述第三类区域仅适用于自然RPPs。
