Natural landslide risk prevention plan — Municipality of Lamothe-Capdeville — Regulated area — Department of Tarn-et-Garonne

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.

针对天然潜在污染风险场所（PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区，以及虽未直接承受风险但可通过预先制定措施规避风险加剧的区域。依据危险等级差异，各区域均需遵循强制性管控规范。相关法规通常将区域划分为三类：1. 禁止建设区（又称红色区域）：该区域危险等级较高，通用规则为禁止一切建设活动；2. 限制建设区（又称蓝色区域）：该区域危险等级为中等，建设项目需遵循适配风险类型的管控要求；3. 非直接风险影响区：该区域虽未直接暴露于风险中，但各类建设工程、开发项目或农业、林业、手工业、商业及工业场所可能加剧既有风险或引发新风险，因此需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。此类区域仅适用于天然潜在污染风险场所（RPPs）。
