Regulatory zoning of the PSS flooding of the commune of Chélan, Arouède 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.热尔省（Gers）境内舍朗（Chélan）与阿鲁埃德（Arouède）市镇的PSS洪水管控区划。针对各类防洪风险预防规划（PPRIs），《环境法典》第L562-1条将区划划分为两类：受风险直接影响区域，以及虽未直接暴露于风险但可采取措施避免风险加剧的区域。依据危险等级的不同，每类区域均需遵循可强制执行的管控细则。相关管控规则通常将区划分为三类：1. 禁建区（又称“红色区域”）：危险等级较高，通用管控规则为禁止建设活动；2. 指定建设区（又称“蓝色区域”）：危险等级中等，建设项目需遵循适配问题类型的管控要求；3. 虽未直接暴露于风险，但各类建设、工程、开发项目或农场（含农业、林业、手工业、商业及工业类农场）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（参见《环境法典》第L562-1条）。此类区划仅适用于天然RPP（RPPs）。
