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.针对天然风险防护场所（natural RPPs），《环境法典》（L562-1条款）将相关区域划分为两类：易受风险区域，以及虽未直接暴露于风险但需采取措施以避免风险加剧的区域。依据危险等级差异，每类区域均需遵循强制性监管规定。 监管规则通常将区域划分为以下三类： 1. 被称为"红区"的禁止建设区域：当危险等级较高时，通用规则为禁止开展任何建设活动； 2. 被称为"蓝区"的合规管制区域：该区域危险等级为中等，建设项目需遵守适配风险类型的专属合规要求； 3. 虽未直接暴露于风险，但建设、工程、开发活动或农业、林业、手工业、商业及工业行为可能加剧风险或引发新风险的区域：该类区域需遵守禁止性规定或特殊管控要求（参见《环境法典》L562-1条款）。 该类区域仅适用于天然风险防护场所（natural RPPs）。
