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.

针对天然风险防护区（PPRs），《环境法典》于条款L562-1中划定两类基础区划：风险暴露区域，以及虽未直接暴露于风险但可通过预设措施规避风险加剧的区域。
依据危险等级的不同，每类区划均需遵循可强制执行的管控细则。相关法规通常将上述区划进一步细分为三类：
1. 建筑禁止区（又称"红色区域"）：该区域危险等级较高，基本原则为全面禁止建筑活动；
2. 合规管控区（又称"蓝色区域"）：该区域危险等级为中等，相关工程建设项目需遵循适配具体风险类型的管控要求；
3. 间接风险暴露区：此类区域虽未直接面临风险，但各类建筑、工程、开发项目或农林牧渔、手工业、商业及工业活动均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管控要求（参见《环境法典》条款L562-1）。上述第三类区划仅适用于天然RPPs（RPPs）。
