PPRM Montdidier Restricted Area

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.

针对自然风险防护区域（Natural PPRs），《环境法典》（Environmental Code）第L562-1条划定了两类核心区域：风险暴露区域，以及虽未直接面临风险但可采取预判性措施以避免风险加剧的区域。依据危险等级的不同，每类区域均需遵循可强制执行的管控规则。相关法规通常将区域细分为以下三类：1. 禁建区域（又称“红色区域”）：该区域危险等级较高，基本原则为全面禁止建设活动；2. 规制区域（又称“蓝色区域”）：该区域危险等级为中等，建设项目需遵循适配问题类型的专项管控要求；3. 非直接风险暴露区域：该区域内的建设工程、开发项目以及农业、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，因此需遵守禁令或管控要求（详见《环境法典》第L562-1条）。此类区域仅适用于自然风险防护计划区域（Natural RPPs）。
