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RPP区域（natural RPPs），《环境法典》（L562-1条）明确划定了两类区域：其一为风险易感区域（risk-prone areas），其二为未直接暴露于风险但可采取措施规避风险升高的区域。依据危险等级的差异，每类区域均需遵循可强制执行的监管规范。 该类监管规范通常将区域划分为三类： 1. 禁止建设区域（Building prohibited areas），即俗称的“红色区域（red zones）”：当危险度（D’aléa）较高时，通用规则为全面禁止建设行为； 2. 受监管约束区域（areas subject to requirements），即“蓝色区域（blue zones）”：此类区域危险等级为中等，建设项目需遵守适配具体问题类型的监管要求； 3. 非直接风险暴露区域：此类区域未直接暴露于风险，但区内的建设工程、开发活动及农业、林业、手工业、商业与工业活动均可能加剧风险或引发新风险，因此需遵循相关禁令或规定（详见《环境法典》L562-1条）。 该最后一类区域仅适用于自然RPP区域（natural RPPs）。
