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.自然灾害预防计划（Natural Hazard Prevention Plan, PPRN）的管控区划已依据COVADIS的国家级规范完成数字化处理。针对自然类灾害预防计划（PPRs），《环境法典》（Environmental Code）在条款L562-1中划定了两类区划：风险暴露区域，以及虽未直接面临风险但可预先采取措施以规避风险加剧的区域。 根据灾害等级的差异，每类区划均需遵循可强制执行的管控规则。相关法规通常将区划划分为三类： 1. 建筑禁建区（俗称"红区"）：该区域灾害等级较高，通用规则为禁止一切建设活动； 2. 合规建设区（俗称"蓝区"）：该区域灾害等级中等，建设项目需遵循适配于具体风险类型的管控要求； 3. 间接风险影响区：该区域虽未直接面临风险，但任何建设工程、开发活动或农业、林业、手工业、商业及工业类农场均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（详见《环境法典》条款L562-1）。该类区划仅适用于自然类灾害预防计划（RPPs）。
