Natural Risk Prevention Plan (NRPP) Restricted Areas Durenque Basin Flood — Tarn

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PPR（PPR），《环境法典》（L562-1条款）划定了两类区域：风险暴露区域，以及未直接暴露于风险，但可通过预先制定管控措施以规避风险加剧的区域。依据危险等级的不同，每类区域均需遵循可强制执行的管控要求。相关法规通常将区域划分为以下三类：1. 建筑禁止区（又称"红色区域"）：该区域危险等级较高，原则上禁止任何建设活动；2. 特定管控区（又称"蓝色区域"）：该区域危险等级为中等，相关项目需遵循适配风险类型的管控要求；3. 非直接风险暴露区：该区域虽未直接暴露于风险，但各类建设工程、作业项目、开发活动，或农业、林业、手工业、商业及工业类经营场所可能加剧既有风险或引发新风险，因此需遵循相关禁止性规定或管控要求（参见《环境法典》L562-1条款）。该类区域仅适用于天然RPP（RPP）场景。
