Natural Hazard Prevention Plan — All Regulated Areas — 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PPRs（PPRs），《环境法典》（Environmental Code）在条款L562-1中划定了两类区域：风险暴露区域，以及虽未直接面临风险但可预先采取措施以避免风险加剧的区域。 依据危险等级的不同，每类区域均需遵循具有强制执行力的管控要求。相关法规通常将区域划分为三类： 1. 被称为"红色区域"的禁止建设区：该区域危险等级较高，通用规则为禁止任何建设行为； 2. 被称为"蓝色区域"的特定管控区：该区域危险等级为中等，相关工程建设需符合适配问题类型的管控要求； 3. 虽未直接面临风险，但任何建设工程、作业项目、开发活动或农业、林业、手工业、商业及工业类农场/经营场所均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（详见《环境法典》条款L562-1）。该类区域仅适用于天然RPPs。
