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.针对自然风险预防区域（natural PPRs），《环境法典》第L562-1条划定了两类管控区域：风险暴露区域，以及未直接面临风险但可通过预先采取措施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管控规则。相关法规通常将区域划分为以下三类： 1. 建筑禁止区（俗称"红色区域"）：该区域危险等级较高，原则上禁止一切建设活动； 2. 法定管控区（俗称"蓝色区域"）：该区域危险等级为中等，相关项目需遵循适配具体风险类型的合规要求； 3. 第三类区域：未直接面临风险，但各类建设工程、开发活动以及农林牧渔、手工业、商业、工业经营业态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合规要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然风险防护区域（natural RPPs）。
