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RPPs，《环境法典》（第L562-1条）将区域划分为两类：风险易发区域，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。依据危险等级，每类区域均需遵守强制性监管规范。该类规范通常将区域划分为三种类型：1. 建筑禁建区（俗称"红区"）：当危险等级较高时，通用规则为禁止一切建设行为；2. 需适配特定监管要求的区域（俗称"蓝区"）：当危险等级为中等时，建设项目需遵循与风险类型相匹配的监管要求；3. 非直接风险暴露区域：此类区域内的建设工程、开发活动或农业、林业、手工业、商业及工业活动可能加剧既有风险或引发新的风险，因此需遵守相关禁建要求或监管规定（参见《环境法典》第L562-1条）。该最后一类区域仅适用于天然RPPs。
