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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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.

针对自然风险预防规划区域（PPR），《环境法典》（Environmental Code）第L562-1条将其划分为两类区域：风险暴露区域，以及未直接面临风险但可采取措施避免风险加剧的区域。依据危险等级的不同，每类区域均需执行可强制实施的管控方案。
法规通常将区域划分为三类：
1. 禁止建设区域，俗称“红区”：该区域危险等级较高，通用规则为实施建设禁令；
2. 法定规管区域，亦称“蓝区”：该区域危险等级中等，相关项目需遵守适配于问题类型的合规要求；
3. 未直接面临风险，但建设工程、开发活动或农、林、手工业、商业及工业经营可能加剧既有风险或引发新风险的区域，该类区域需遵守禁止性规定或相关合规要求（参见《环境法典》第L562-1条）。
上述第三类区域仅适用于自然风险预防规划区域（RPP）。
