Regulatory zoning of PPRN approved in Haute-Garonne

Regulatory zoning of Natural Risk Prevention Plans: flooding, terrain movement and avalanche. This includes RIPs (floods) and multi-hazard PPRNs. But this does not include dry RPPs (risk of clay withdrawal-swelling) that are in the layer: L_ZONE_REG_PPRS_031.TAB 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” where the hazard level is high and the general rule is the prohibition on construction; 2- “required areas” 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).自然风险防控规划监管区划：洪涝、地形位移与雪崩。 本数据集涵盖洪涝风险区划（RIPs）与多灾种自然风险防控规划（PPRNs），但不包含图层L_ZONE_REG_PPRS_031.TAB中的干缩-膨胀黏土风险区划（RPPs）。 针对自然风险防控规划（PPRs），《环境法典》（Environmental Code）第L562-1条将其区划分为两类：风险暴露区，以及虽未直接面临风险但可通过预设措施规避风险加剧的区域。 根据灾害等级，每类区域均需遵循可强制执行的管控规则。现行法规通常将区划划分为三类： 1. 禁止建设区：灾害等级较高，通用管控规则为禁止建设； 2. 管控要求区：灾害等级中等，建设项目需适配风险类型制定针对性管控要求； 3. 非直接风险暴露区：该区域内的建设、工程、开发活动或农业、林业、手工业、商业及工业经营场所可能加剧既有风险或引发新风险，需遵守相关禁令或管控要求（详见《环境法典》第L562-1条）。
