Regulatory zoning of the PPRN flooding of the municipality of Vergoignan 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）韦尔瓜南（Vergoignan）市镇的自然风险预防规划（PPRN）洪涝风险管控区划。针对洪涝风险预防规划（PPRI），法国《环境法典》第L562-1条将相关区划划分为两类：受风险直接影响区域，以及虽未受风险直接影响但可通过预先采取管控措施避免风险加剧的区域。根据危险等级的不同，每类区域均需适用具有强制执行力的建设管控细则。相关管控规则通常将区划分为以下三类：1. 禁止建设区（红色区域）：该区域危险等级较高，通用管控规则为禁止一切建设活动；2. 限制建设区（蓝色区域）：该区域危险等级中等，相关建设项目需遵循适配问题类型的管控要求；3. 虽未受风险直接影响，但各类建设、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的区域：该类区域需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。上述第三类区划仅适用于自然风险预防规划（PPRN）。
