Dataset Direct Download Service (WFS): Regulated areas of the plan for the prevention of natural hazards of the municipality of Lassur

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的国家规范，完成了《自然灾害预防规划》（Natural Hazard Prevention Plan，缩写PPRN）中管制区划的数字化处理。针对自然风险类防灾规划，《环境法典》（Environmental Code）于条款L562-1中划定了两类区划：一是风险暴露区，二是虽未直接暴露于风险，但可通过前置管控措施避免风险加剧的区域。 根据灾害等级差异，每类区划均需遵循可强制执行的管控细则。相关法规通常将区划细分为三类： 1. “禁止建设区”（俗称“红区”）：此类区域灾害等级较高，通用规则为全面禁止建设行为； 2. “规划管控区”（俗称“蓝区”）：此类区域灾害等级为中等，相关工程建设需遵守适配风险类型的专项管控要求； 3. 未直接暴露于风险，但各类建设、工程、开发活动或农、林、手工业、商业、工业类经营场所可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（详见《环境法典》L562-1条款）。该类区划仅适用于自然风险类防灾规划。
