For natural RPPs, the Environmental Code defines two categories of areas (L562-1): risk-prone areas and areas that are not directly exposed to risks but on which measures may be provided for avoid increasing the risk. Depending on the hazard level, each area is subject to a enforceable regulation. The regulations generally distinguish three types of zones: 1- “Building prohibited areas”, so-called “red zones”, when the level of D’aléa is strong and that the general rule is the prohibition on construction; 2- “areas” subject to requirements, referred to as ‘blue zones’, where the hazard level is average and that projects are subject to requirements adapted to the type of issue; 3- Areas not directly exposed to risks, but where constructions, works, development or agricultural, forestry, artisanal, commercial or industrials could aggravate risks or cause new, submitted prohibitions or prescriptions (cf. Article L562-1 of the Environmental Code). This last category applies only to natural RPPs.针对自然风险敏感区域（Risk-Prone Places，RPPs），《环境法典（Environmental Code）》（L562-1条款）划定了两类区域：一是风险易发区，二是未直接暴露于风险中，但可采取防控措施以避免风险加剧的区域。依据风险烈度等级的不同，每类区域均需遵守对应的强制性监管规定。此类监管规定通常将区域划分为三类：1. “禁止建设区”，即所谓的“红色区域”：当风险烈度较高时，通用规则为禁止一切建设行为；2. “需满足监管要求的区域”，即“蓝色区域”：此类区域风险烈度中等，建设项目需根据具体问题类型适配相应监管要求；3. 非直接风险暴露区域：此类区域虽未直接面临风险，但任何建设、工程、开发活动或农业、林业、手工业、商业及工业行为均可能加剧风险或引发新风险，因此需遵守相关禁令或规定（详见《环境法典》L562-1条款）。该第三类区域仅适用于自然风险敏感区域。
