Natural risk zoning: Creuse PPRN Regulated Area on the agglomeration of Argenton sur Creuse

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 areas:1- ‘Building prohibited areas’, so-called ‘red areas’, where the hazard level is high and the general rule is the construction ban;2- ‘prescription areas’, known as ‘blue zones’, where the hazard level is medium and 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, crafts, 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）在条款L562-1中划定两类区域：风险暴露区域，以及虽未直接面临风险但可预先制定防控措施以规避风险升级的区域。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三类：1. 「禁止建设区域」，俗称「红色区域」：该区域危险等级较高，核心管控规则为全面禁止建设活动；2. 「规制管控区域」，又称「蓝色区域」：该区域危险等级为中等，相关建设项目需遵循适配于风险类型的具体管控要求；3. 虽未直接面临风险，但任何建设、工程、开发活动或农业、林业、手工业、商业及工业类经营场所均可能加剧既有风险或引发新风险的区域：该类区域需遵守相关禁令或管控要求（参见《环境法典》条款L562-1）。上述第三类区域仅适用于自然RPPs。
