Map Viewing Service (WMS) of the dataset: Regulated areas of the plan for the prevention of natural hazards of the municipality of ORNOLAC-USSAT-LES-BAINS

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.《自然灾害防治计划》（Natural Hazard Prevention Plan，简称PPRN）的监管区划已依据COVADIS的国家规范完成数字化转换。 针对自然类PPRN，《环境法典》划定了两类区划（L562-1）：风险暴露区域，以及虽未直接面临风险但可通过措施避免风险加剧的区域。 依据灾害等级，各区域均需执行强制性建设管控要求。法规通常将区划分为三类： 1. “禁止建设区”（亦称“红色区域”）：此类区域灾害等级较高，通用规则为严禁任何建设活动； 2. “约束建设区”（亦称“蓝色区域”）：此类区域灾害等级中等，建设项目需遵循适配问题类型的管控要求； 3. 虽未直接暴露于风险，但建设、工程、开发活动或农场、农业、林业、手工业、商业、工业相关业态可能加剧风险或引发新风险的区域，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）。该类区划仅适用于自然类RPP。
