Regulatory zoning of the Forest Fire Risk Prevention Plan (PPRIF) of the municipality of Furiani in Upper Corsica

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》确立了自然灾害防治规划体系。该体系是国家开展风险防控工作的核心工具，其目标为对风险区域内的城市规划与土地利用开发活动实施动态监测。

针对自然风险防控规划（PPRs），《环境法典（Environmental Code）》于条款L562-1中划定了两类区域：一是风险暴露区域，二是虽未直接面临风险，但需采取防控措施以避免风险加剧的区域。

依据灾害风险等级的差异，各区域均需执行对应的强制性管控要求。现行法规通常将区域划分为以下三类：
1. "禁止建设区域（红色区域）"：该区域风险等级较高，原则上严禁开展任何建设活动；
2. "限制建设区域（蓝色区域）"：该区域风险等级中等，建设项目需遵循适配风险类型的管控要求；
3. 非直接风险暴露区域：此类区域虽未直接承受风险，但各类建设、工程、开发活动以及农业、林业、手工业、商业或工业经营场所（如农场）可能加剧既有风险或引发新的风险，因此需遵守相应的管控禁令或要求（详见《环境法典》条款L562-1）。
