Regulatory zoning of the PPRN flooding of the commune of Lias 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）里亚斯公社PPRN（自然风险防治规划，Natural Risk Prevention Plan）洪水管控区划。 根据《环境法典》第L562-1条，PPRI（工业风险防治规划，Industrial Risk Prevention Plan）将区划分为两类：受风险直接影响区域，以及虽未直接受风险波及但可通过预先制定措施规避风险加剧的区域。依据危险等级，每类区域均需执行强制性管控规则。 该管控规则通常将区划分为三类： 1. "建筑禁建区"（又称"红区"）：危险等级较高，通用管控要求为禁止建设活动； 2. "管控建设区"（又称"蓝区"）：危险等级中等，建设项目需遵守适配风险类型的特定要求； 3. 虽未直接受风险影响，但各类建设、工程、开发活动或农牧场、农林、手工业、商业及工业经营可能加剧既有风险或引发新风险的区域，需遵守禁令或特定管控要求（参见《环境法典》第L562-1条）。该第三类区划仅适用于天然RPPs（风险防治规划，Risk Prevention Plans）。
