Regulated zone of the plan for the prevention of natural hazards of Cordon (Haute-Savoie) — approved on 31/07/2013

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PPRs，《环境法典》（Environmental Code）划定了两类区域（条款编号L562-1）：风险暴露区域，以及虽未直接面临风险，但可预先采取措施规避风险加剧的区域。 依据危险等级差异，每类区域均需遵循强制性管控要求。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”）”：此类区域危险等级较高，原则上禁止一切建设行为； 2. “合规建设区域（又称“蓝色区域”）”：此类区域危险等级中等，相关工程建设需遵循适配风险类型的管控要求； 3. “非直接风险暴露区域”：此类区域虽未直接面临风险，但任何建设工程、开发活动或农林牧渔、手工业、商业及工业经营行为均可能加剧既有风险或引发新的风险，因此需遵守相关禁止性规定或管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然RPPs。
