Regulatory zoning of the PPRN flooding of the commune of Urdens 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）欧尔当市镇（Urdens）洪水型自然风险防治规划（PPRN）区划监管规则。针对PPRIs（PPRIs），《环境法典》在第L562-1条中划定了两类区域：直接受风险影响区域，以及虽未直接暴露于风险但可通过预设措施避免风险加剧的区域。依据风险等级差异，每类区域均需遵守可强制执行的建设管控要求。 监管规则通常区分三类区域： 1. 禁止建设区（俗称"红色区域"）：此类区域风险等级较高，一般性管控规则为禁止建设活动； 2. 限制建设区（俗称"蓝色区域"）：此类区域风险等级中等，建设项目需遵守适配问题类型的相关管控要求； 3. 虽未直接暴露于风险，但建设活动、工程施工、开发项目或农业、林业、手工业、商业及工业类经营主体可能加剧既有风险或引发新风险的区域，此类区域需遵守禁止性规定或管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于天然RPPs（RPPs）。
