Regulatory zoning of PPRN flooding of the municipality of Marestaing 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.热尔省马雷斯唐市镇洪涝自然风险防治规划（PPRN）的管控区划。 针对PPRIs，法国《环境法典》第L562-1条划定了两类区域：受风险直接影响区域，以及虽未直接暴露于风险但可采取预判性措施以避免风险加剧的区域。 依据危险等级的不同，每类区域均需遵守可强制执行的建设管控规则。 管控规则通常区分以下区域： 1. “禁止建设区”（又称“红色区域”）：此类区域危险等级较高，通用规则为禁止开展任何建设活动； 2. “规定建设区”（又称“蓝色区域”）：此类区域危险等级中等，建设项目需遵守适配风险类型的相关管控要求； 3. 虽未直接暴露于风险，但农业、林业、手工业、商业或工业类建设、工程、开发项目或农场可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。 该类区域的适用范围仅限定于天然RPPs。
