Dataset Direct Download Service (WFS): Regulated zone of the Seyssel Natural Risk Prevention Plan (Haute-Savoie) — approved on 08/06/1999

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.针对自然风险防范区域（PPRs），《环境法典》（L562-1条款）划定了两类区域：风险暴露区，以及未直接面临风险但可预先采取措施避免风险加剧的区域。依据危险等级的不同，每类区域均需遵循强制性管控规则。相关法规通常将区域划分为以下三类： 1. “禁止建设区”，亦称“红色区域”：该区域危险等级较高，基本原则为禁止开展任何建设活动； 2. “规划管控区”，亦称“蓝色区域”：该区域危险等级中等，相关项目需适配问题类型落实针对性管控要求； 3. 未直接面临风险的区域：在此区域内进行的建设、工程、开发活动或农业、林业、手工业、商业及工业经营行为，可能加剧既有风险或引发新的风险，因此需遵守禁止性规定或管控要求（详见《环境法典》第L562-1条）。 前述第三类区域仅适用于自然风险防范区域（RPPs）。
