Plans for the prevention of natural hazards were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor the development of urban planning and land use in areas at risk. 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).1995年2月2日《加强环境保护法案》（Act of 2 February 1995 on strengthening the protection of the environment）确立了自然灾害预防规划，该规划是国家风险预防领域的核心工具，其目标是对风险区域内的城市规划与土地利用开发情况进行监测。 针对自然风险预防规划（Natural PPRs），《环境法典》（Environmental Code）第L562-1条将区域划分为两类：受风险直接影响区域，以及虽未直接暴露于风险但可采取措施避免风险加剧的区域。 根据灾害等级不同，各区域需执行强制性管控要求。相关法规通常将区域划分为三类： 1. 建筑禁止区（又称"红色区域"）：该区域灾害等级较高，通用规则为禁止任何建筑活动； 2. 管控开发区（又称"蓝色区域"）：该区域灾害等级为中等，相关建设项目需遵循适配问题类型的管控要求； 3. 非直接风险暴露区域：此类区域虽未直接面临风险，但任何建筑、工程、开发活动或农业、林业、手工业、商业及工业类经营主体均可能加剧既有风险或引发新风险，因此需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。
