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.

针对天然风险预防与保护区域（natural RPPs），《环境法典》（Environmental Code）于条款L562-1中将其划分为两类：易受风险波及区域，以及未直接面临风险但可采取措施避免风险加剧的区域。根据灾害等级的不同，每类区域均需遵守可强制执行的监管规定。此类监管规定通常将区域划分为三种类型：
1. “禁止建设区域”，即所谓“红区”：当灾害等级较高时，通用规则为禁止任何建设行为；
2. “受约束区域”，即“蓝区”：此类区域灾害等级为中等，建设项目需遵守适配相关问题类型的约束要求；
3. 未直接面临风险，但建设、工程、开发活动或农业、林业、手工业、商业及工业活动可能加剧风险或引发新风险的区域，需遵守相关禁令或规定（参见《环境法典》条款L562-1）。此类最后一类区域仅适用于天然风险预防与保护区域（natural RPPs）。
