Risk — 41DDT19980003 IRPP Regulated Area (Black) in Loir-et-Cher

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.

针对自然风险预防规划（PPRs），《环境法典》第L562-1条将区域划分为两类：风险暴露区，以及虽未直接面临风险但需预先制定防控措施以避免风险加剧的区域。依据危险等级差异，每类区域均需执行可强制执行的管控方案。
该法规通常将区域划分为三种类型：
1. 禁止建设区（又称"红色区域"）：此类区域危险等级较高，通用规则为禁止任何建设活动；
2. 特定管控区（又称"蓝色区域"）：此类区域危险等级中等，建设项目需遵循适配问题类型的相关管控要求；
3. 虽未直接面临风险，但建设、工程、开发活动或农场，以及农业、林业、手工业、商业或工业经营活动可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。该第三类区域仅适用于自然风险预防规划（RPPs）。
