Plan for the prevention of natural risks of land movement — Municipality of Roquecor — Regulatory 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.针对自然风险防护区（natural PPRs），《环境法典（Environmental Code）》第L562-1条款将其划分为两类区域：一是风险暴露区，二是虽未直接承受风险但可通过采取相关措施规避风险加剧的区域。 根据危险等级的不同，每一类区域均需遵循可强制执行的整治要求。相关法规通常将区域划分为三类： 1. 禁止建设区（俗称“红区”）：该区域危险等级较高，原则上禁止任何建设行为； 2. 管制建设区（俗称“蓝区”）：该区域危险等级中等，建设项目需遵循适配风险类型的相关要求； 3. 间接风险管控区：该区域虽未直接暴露于风险之中，但各类建设工程、作业项目、开发活动、农林场所、农场以及手工业、商业、工业经营活动均可能加剧既有风险或引发新的风险，因此需遵循相关禁止或管控要求（参见《环境法典》第L562-1条款）。此类区域仅适用于自然风险防护区（natural RPPs）。
