The regulated zoning of the Natural Hazard Prevention Plan (PPRN) is digitised in accordance with the national requirements of COVADIS.
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.

自然风险预防计划（Natural Hazard Prevention Plan，PPRN）的合规区划已依据COVADIS的国家相关要求完成数字化转换。针对自然风险预防计划，环境法典（Environmental Code）在条款L562-1中将区划划分为两类：一是风险暴露区，二是虽未直接面临风险，但可预先采取措施以避免风险加剧的区域。根据风险等级的不同，各类区划需遵守可强制执行的管控细则。相关法规通常将区划分为三类：1. 建筑禁止区（又称"红色区域"）：此类区域风险等级较高，原则上禁止任何建设活动；2. 依规建设区（又称"蓝色区域"）：此类区域风险等级中等，相关建设项目需遵守适配问题类型的管控要求；3. 非直接风险暴露区：区内的建设工程、开发活动或农业、林业、手工业、商业及工业类经营场所可能加剧既有风险或引发新风险，因此需遵守相关禁令或管控要求（详见环境法典第L562-1条）。该类区划仅适用于自然风险预防计划（RPPs）。
