Regulated area of the Predictable Natural Risk Prevention Plan of the commune of Salon de Provence — Bouches-du-Rhône — 13DDTM19850140 (MOUVEMENT DE TERRAIN — Eboulement, CHUTES DE PIERRES AND BLOCS AND SEISME)

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，《环境法典（Environmental Code）》第L562-1条将区域划分为两大类：风险暴露区域，以及虽未直接面临风险但可预先采取措施规避风险加剧的区域。根据危险等级的不同，每类区域均需遵守可强制执行的管控要求。相关监管法规通常将上述区域划分为三类：1. "禁止建设区域"，俗称"红色区域"：该区域危险等级较高，通用准则为严禁开展任何建设活动；2. "指定管控区域"，俗称"蓝色区域"：该区域危险等级为中等，相关项目需适配问题类型遵守对应合规要求；3. 虽未直接面临风险，但建设工程、工程作业、开发项目或农业、林业、手工业、商业及工业经营活动可能加剧既有风险或引发新的风险的区域，此类区域需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。上述第三类区域仅适用于天然RPPs。
