For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk.
Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones:
1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction;
2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue;
3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.

针对自然风险防范区域（natural PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及虽未直接面临风险但可采取预判性措施以避免风险加剧的区域。依据危险等级的差异，每类区域均需遵循可强制执行的管控要求。相关法规通常将区域划分为三类：1. 禁建区（又称"红色区域"）：该区域危险等级较高，通用管控规则为禁止一切建设活动；2. 合规管控区（又称"蓝色区域"）：该区域危险等级中等，相关项目需遵循适配问题类型的专项管控要求；3. 非直接风险暴露区域：该区域虽未直接面临风险，但建设工程、开发项目、农林场所以及手工业、商业、工业活动可能加剧既有风险或引发新风险，因此需遵守相关禁令或管控要求（详见《环境法典》第L562-1条）。此类区域仅适用于自然RPPs（natural RPPs）。
