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.

针对自然风险防治规划（Natural Risk Prevention Plans, PPRs），《环境法典》（Environmental Code）的L562-1条款将区域划分为两类：受风险直接影响的区域，以及虽未直接暴露于风险之中，但可预先制定措施避免风险加剧的区域。根据危险等级的不同，每类区域均需遵循具有强制执行力的管控要求。相关法规通常将区域划分为三类：1. “禁止建设区域”，又称“红色区域”：该区域危险等级较高，通用规则为禁止建设活动；2. “管控区域”，亦称“蓝色区域”：该区域危险等级为中等，相关建设项目需遵守适配问题类型的专项管控要求；3. 虽未直接面临风险，但各类建设工程、施工项目、开发活动或农场、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风险的区域，需遵守禁止性规定或管控要求（详见《环境法典》L562-1条款）。此类区域仅适用于自然风险防治规划（Natural Risk Prevention Plans, RPPs）。
