For natural PPRs, 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 three 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. This RPP defines 2 main areas: — red: principle of prohibition on construction — orange: principle of permission to build with prescription These two areas are themselves subdivided into 6 sectors: R1: Flood Expansion Fields in Low Hazard R2: Flood Expansion Fields in Medium Hazardous R3: Zone of strong hazards R3u: Urban centre area subjected to a severe hazard O1: low-risk urbanised area O2: urbanised Medium Hazardous Area针对自然风险预防规划（Risk Prevention Plan，PPR），法国环境法典第L562-1条将区划划分为两类：受风险影响区域，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。 根据危险等级不同，每类区划均需遵循可强制执行的管控要求。相关法规通常将区划分为三类： 1. 建筑禁建区（又称"红色区域"）：该区域危险等级较高，核心管控规则为禁止建设活动； 2. 合规管控区（又称"蓝色区域"）：该区域危险等级中等，建设项目需遵循适配风险类型的管控要求； 3. 非直接受风险影响区域：该区域内的建设工程、开发活动或农、林、手工业、商业及工业业态可能加剧既有风险或引发新风险，需遵循禁建或管控要求（参见法国环境法典第L562-1条）。该类区划仅适用于自然类风险预防规划（Risk Prevention Plan，RPP）。 本风险预防规划（RPP）划定两类主区划： — 红色区域：建设活动禁建原则 — 橙色区域：需满足管控要求方可开展建设活动的许可原则 上述两类主区划进一步细分为6个分区： R1：低危险等级洪水行洪区 R2：中危险等级洪水行洪区 R3：高危险等级区域 R3u：遭受严重危险的中心城区 O1：低风险城市化区域 O2：中风险城市化区域
