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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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.

针对天然风险防护规划（PPR），《环境法典（Environmental Code）》第L562-1条划定了两类区域：受风险直接暴露的区域，以及虽未直接面临风险但可采取措施避免风险加剧的区域。依据风险等级，每类区域均需执行可强制执行的管控方案。相关法规通常将区域划分为以下三类：
1. 禁建区（俗称“红区”）：此类区域风险等级较高，原则上禁止开展建设活动；
2. 管控要求区（俗称“蓝区”）：风险等级为中等，区内项目需适配针对具体风险类型的管控要求；
3. 未直接受风险影响的区域：区内的建设工程、开发活动或农、林、手工业、商业、工业类经营场所可能加剧既有风险或引发新风险，需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于天然风险防护规划（RPP）。
