PPRN — RPP Regulated Area Flooding — VOINEMONT (54591)

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PPR区域，《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及未直接暴露于风险但可预先采取措施规避风险加剧的区域。 依据危险等级的不同，每类区域均需遵守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，基本原则为禁止一切建设活动； 2. 管控区（又称“蓝色区域”）：该区域危险等级中等，相关工程建设需符合针对该类风险问题制定的适配性要求； 3. 未直接承受风险，但因建设、工程作业、开发项目或农、林、手工业、商业及工业类经营场所可能加剧风险或引发新风险的区域，此类区域需遵守相关禁止性规定或适配要求（详见《环境法典》第L562-1条）。 上述第三类区域仅适用于自然RPP区域。
