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

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.本数据集内，自然灾害风险防治规划（Natural Hazard Prevention Plan, PPRN）的合规土地分区管控内容，已依据COVADIS的国家规范完成数字化处理。针对自然类PPRN，《环境法典》（Environmental Code）将区划划分为两类（L562-1条款）：直接受灾害风险影响的区域，以及虽未直接暴露于灾害风险但可采取措施避免风险加剧的区域。依据灾害风险等级，各区域均需遵守可强制执行的开发建设管控规则。监管规则通常将区划划分为以下三类：1. "禁建区"，又称"红色区域"：此类区域风险等级较高，通用管控规则为禁止任何建设活动；2. "依规建设管控区"，又称"蓝色区域"：此类区域风险等级中等，建设项目需根据风险类型适配相应管控要求；3. 虽未直接暴露于灾害风险，但任何建设、工程、开发活动或农场、农业、林业、手工业、商业及工业项目均可能加剧既有风险或引发新风险的区域，此类区域需遵守相关禁建或管控要求（详见《环境法典》L562-1条款）。该第三类区划仅适用于自然类RPPs。
