PPRN — RPP Regulated Area Flood — VALLEROY (54542)

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.针对自然风险预防区域（Natural PPRs），《环境法典》划定了两类管控区域（对应条款编号L562-1）：其一为风险暴露区域，其二为虽未直接面临风险，但可通过预先制定措施避免风险加剧的区域。 根据危害等级的不同，每类区域均需遵循可强制执行的管控规则。法规通常将区域划分为以下三类： 1. 禁止建设区（又称“红色区域”）：该区域危害等级较高，原则上禁止任何建设活动； 2. 管控建设区（又称“蓝色区域”）：该区域危害等级为中等，区内项目需遵循适配风险类型的管控要求； 3. 间接风险管控区：该区域虽未直接面临风险，但区内的各类建设工程、开发活动或农、林、手工业、商业及工业类农场、经营场所可能加剧既有风险或引发新的风险，因此需遵守相关禁令或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然风险预防区域（Natural RPPs）。
