Restricted area of the PPRN flooding of the municipality of Castéra-Verduzan (Gers)

Regulatory zoning of the PPRN flooding of the municipality of Castéra-Verduzan in the department of Gers. For PPRIs, 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 two 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.本数据集涵盖热尔省卡斯特拉-韦尔迪赞市PPRN洪水管制区划相关内容。针对PPRI，《法国环境法典》第L562-1条划定了两类区域：直接受风险影响的区域，以及虽未直接暴露于风险但可通过预设管控措施避免风险加剧的区域。依据风险等级，每类区域均需执行可强制执行的管控要求。现行管控法规通常划分三类区域：1. 禁建区（又称“红色区域”）：该区域风险等级较高，通用管控规则为禁止建设活动；2. 管控区（又称“蓝色区域”）：该区域风险等级中等，相关建设项目需遵循适配问题类型的管控要求；3. 非直接暴露风险区域：若在此类区域开展建设、工程作业、开发活动或开设农业、林业、手工业、商业及工业类经营场所，可能加剧既有风险或引发新风险，此类区域需遵守相关禁令或管控要求（详见《法国环境法典》第L562-1条）。上述第三类区域仅适用于天然RPP区域。
