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.针对自然风险预防区域（PPRs），《环境法典》（条款编号L562-1）划定了两类区域：风险暴露区域，以及未直接面临风险但可通过预先采取措施规避风险加剧的区域。 根据危险等级的差异，每类区域均需遵守强制性建设管控规范。相关法规通常将区域划分为三类： 1. 禁止建设区，亦称“红色区域”：该区域危险等级较高，原则上禁止任何建设活动； 2. 限制建设区，亦称“蓝色区域”：该区域危险等级中等，相关建设项目需遵循适配风险类型的管控要求； 3. 非直接风险暴露区域：此类区域内的建设工程、作业项目、开发活动，以及农业、林业、手工业、商业及工业经营场所可能加剧既有风险或引发新的风险，因此需遵守相关禁止性规定或管控要求（详见《环境法典》L562-1条款）。该类别的适用范围仅涵盖自然风险预防区域（RPPs）。
