PPRI Ept (Regulated area)

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.

针对自然风险预防区域（PPRs），法国《环境法典》第L562-1条划定了两类区域：受风险影响区域，以及虽未直接暴露于风险但可通过采取相关措施避免风险加剧的区域。根据危险等级的不同，每类区域均需遵守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"（俗称"红色区域"）：该区域危险等级较高，原则上禁止任何建设活动；2. "管控建设区域"（又称"蓝色区域"）：该区域危险等级为中等，建设项目需根据具体风险类型遵守适配的管控要求；3. 未直接暴露于风险的区域：在此类区域中，任何建设、工程、开发活动或农业、林业、手工业、商业及工业经营场所均可能加剧既有风险或引发新的风险，需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。前述第三类区域仅适用于自然RPPs。
