Restricted area of the Prevention Plan of the Predictable Natural Risks of the municipality of Gréasque — Bouches-du-Rhône — 13DDTM20020153 (MOVEMENT DE TERRAIN — SOUTERRAINE CARRIERES)

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，《环境法典》（Environmental Code）于L562-1条款中划定了两类区域：风险暴露区域，以及虽未直接暴露于风险但可通过预设措施规避风险加剧的区域。依据危险等级，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. 禁止建设区域（又称红色区域）：该区域危险等级较高，原则上禁止一切建设活动； 2. 规定建设区域（又称蓝色区域）：该区域危险等级中等，建设项目需遵循适配问题类型的相关要求； 3. 非直接风险暴露区域：此类区域虽未直接暴露于风险，但各类建设工程、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的风险，因此须遵守相关禁止性规定或合规要求（详见《环境法典》（Environmental Code）L562-1条款）。该第三类区域仅适用于自然RPPs。
