Map Viewing Service (WMS) of the dataset: Regulated areas of the natural risk prevention plan of the municipality of SAVIGNAC-LES-ORMEAUX

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.自然灾害防治规划（Natural Hazard Prevention Plan，PPRN）的合规分区已按照COVADIS的国家相关要求完成数字化处理。 针对自然类自然灾害防治规划，《环境法典》定义了两类分区（L562-1）：风险暴露区域，以及未直接暴露于风险但可采取措施避免风险加剧的区域。 根据灾害等级差异，每类分区均需遵循可强制执行的建设管控细则。 相关管控规则通常将分区划分为三类： 1. 建筑禁建区（又称"红色区域"）：该区域灾害等级较高，通用规则为禁止一切建设活动； 2. 规划管控区（又称"蓝色区域"）：该区域灾害等级为中等，建设项目需符合适配具体风险类型的管控要求； 3. 非直接风险暴露区：该区域虽未直接暴露于风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业类经营场所（如农场等）可能加剧既有风险或引发新风险，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）。 上述第三类分区仅适用于自然类自然灾害防治规划。
