For Natural Risk Prevention Plans (NPPs), 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.针对自然风险防范计划（Natural Risk Prevention Plans，NPPs），《环境法典》于第L562-1条中划定两类区域：一类为风险暴露区域，另一类为未直接面临风险但可通过预设管控措施避免风险加剧的区域。依据危险等级差异，每类区域均需遵循可强制执行的建设管控要求。 该法规通常将区域细分为三类： 1. **禁止建设区（又称“红区”）**：该区域危险等级较高，基本原则为严禁开展任何建设活动； 2. **限制建设区（又称“蓝区”）**：该区域危险等级为中等，建设项目需遵循适配于风险类型的专属管控要求； 3. **潜在风险关联区**：该区域未直接面临风险，但各类建设、工程、开发活动或农场及农业、林业、手工业、商业及工业业态可能加剧既有风险或引发新风险，需遵循相关禁止或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然风险防范计划。
