Regulatory zoning of the PPRN flooding of the commune of Blousson-Sérian 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.法国热尔省（Gers）布鲁松-塞里扬市镇（Blousson-Sérian）的PPRN洪水防控监管分区。 针对PPRI，《环境法典（Environmental Code）》在条款L562-1中将区域划分为两类：洪水风险暴露区，以及虽未直接面临风险但可采取措施避免风险加剧的区域。根据危险等级，每类区域均需遵守可强制执行的管控要求。 相关法规通常将区域划分为以下三类： 1. 禁止建设区（俗称“红区”）：危险等级较高，原则上禁止任何建设活动； 2. 规定建设区（俗称“蓝区”）：危险等级中等，相关工程建设项目需遵守适配问题类型的管控要求； 3. 虽未直接面临风险，但各类建设、工程、开发活动或农、林、手工业、商业及工业经营行为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》条款L562-1）。该类区域仅适用于天然RPPs场景。
