Dataset Direct Download Service (WFS): Regulatory zoning of the Forest Fire Risk Prevention Plan (PPRIF) of the municipality of Oletta 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日颁布的《加强环境保护法案》确立了自然灾害防治规划。此类规划是国家在风险防治领域的核心管控工具，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动态监测。
针对自然风险防治规划（Natural Preventive Plans for Risks, PPRs），《环境法典》（Environmental Code）第L562-1条将相关区域划分为两类：一是风险暴露区，二是未直接遭受风险威胁，但可采取措施避免风险加剧的区域。
根据灾害风险等级的不同，各区域需遵循相应的强制性管控要求。现行法规通常将区域划分为三类：
1. “建筑禁建区”（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. “合规建设区”（又称“蓝色区域”）：此类区域风险等级中等，建设项目需遵循适配问题类型的相关管控要求；
3. 非直接风险暴露区：此类区域未直接遭受风险威胁，但各类建设工程、开发项目，以及农业、林业、手工业、商业及工业类经营活动或农场可能加剧既有风险或引发新风险，需遵循相应禁令或管控要求（详见《环境法典》第L562-1条）。
