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》（第L562-1条）将其所辖区域划分为两类：易受风险影响区域，以及未直接暴露于风险但需采取措施以避免风险加剧的区域。根据危险等级的不同，每类区域均需遵守强制性监管规定。监管规则通常将区域划分为三类：1. “禁止建设区域”，亦称“红区”：当危险等级较高时，通用规则为禁止任何建设行为；2. “受监管要求约束的区域”，即“蓝区”：此类区域危险等级为中等，建设项目需符合适配具体问题类型的监管要求；3. 未直接暴露于风险的区域，但在此类区域内开展的建设、工程、开发或农业、林业、手工业、商业及工业活动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监管要求（详见《环境法典》第L562-1条）。上述第三类区域仅适用于天然风险防护场所。
