Map Viewing Service (WMS) of the dataset: Regulated areas of the former plan for the prevention of natural hazards of the commune of LE FOSSAT

The regulated zoning of the Natural Hazard Prevention Plan (PPRN) is digitised in accordance with the national requirements of COVADIS. 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.本数据集依据COVADIS的国家相关规范要求，完成了《自然灾害防治规划》（Natural Hazard Prevention Plan, PPRN）的管制区划数字化工作。针对自然类PPRN，《环境法典》（Environmental Code）于条款L562-1中划定两类区划：直接受风险影响区域，以及虽未直接暴露于风险但可采取预防措施以避免风险加剧的区域。依据灾害等级，各区域均需遵循可强制执行的建设管制规则。相关管制规定通常划分出三类区划：1. “禁止建设区”（又称“红色区域”）：此类区域灾害等级较高，通用规则为禁止任何建设活动；2. “限制建设区”（又称“蓝色区域”）：此类区域灾害等级中等，建设项目需适配对应风险类型的相关管制要求；3. 虽未直接暴露于风险，但建设工程、开发项目或农业、林业、手工业、商业及工业性农场等活动可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或管制要求（参见《环境法典》第L562-1条）。该类区划仅适用于自然类RPP。
