Plan for the prevention of natural risks of landslide — Commune d’Auvillar — Regulated area — Department of Tarn-et-garonn

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PPRs（natural PPRs），法国《环境法典》（第L562-1条）划定了两类区域：风险暴露区，以及虽未直接面临风险但可预先制定防控措施以防范风险加剧的区域。 依据危险等级的不同，每类区域均需遵守可强制执行的用地管制要求。法规通常将区域划分为三种类型： 1. “禁止建设区”，亦称“红色区域”：此类区域危险等级较高，基本原则为禁止一切建设活动； 2. “限制建设区”，亦称“蓝色区域”：此类区域危险等级中等，建设项目需符合适配风险类型的合规要求； 3. 虽未直接暴露于风险之中，但各类建设工程、开发项目或农业、林业、手工业、商业及工业经营活动可能加剧既有风险或引发新风险的区域，需遵守禁止性规定或合规管控要求（参见第L562-1条）。该类别的适用范围仅涵盖自然RPPs（natural RPPs）。
