Dataset Direct Download Service (WFS): Regulated zone of the plan for the prevention of natural hazards of Saint-Jean-de-Sixt (Haute-Savoie) — approved on 30/12/2009

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（natural PPRs），《环境法典（Environmental Code）》第L562-1条划定了两类区域：风险暴露区，以及未直接暴露于风险但可采取防控措施以避免风险加剧的区域。根据危险等级的不同，每类区域均需遵循可强制执行的管控规则。相关法规通常将区域划分为三类：1. 建筑禁止区（又称"红色区域"），此类区域危险等级较高，原则上禁止任何建设活动；2. 指定管控区（又称"蓝色区域"），此类区域危险等级中等，相关工程建设需符合针对具体风险类型制定的管控要求；3. 未直接暴露于风险的区域：该类区域内的建设工程、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，需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。该类别的适用范围仅限定于自然RPP（natural RPPs）。
