Marquenterre Bay of Somme Restricted Area Reference Level Isocontours

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.

针对自然风险预防规划（PPR），《环境法典》（Environmental Code）在L562-1条款中划定了两类区域：风险暴露区域，以及未直接暴露于风险但可采取措施规避风险加剧的区域。依据危害等级的不同，每类区域均需遵守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. “禁止建设区域”，亦称“红色区域”，该区域危害等级较高，通用规则为禁止建设；
2. “规制区域”，亦称“蓝色区域”，该区域危害等级中等，相关项目需遵守适配问题类型的合规要求；
3. 未直接暴露于风险，但建设工程、开发活动或农林牧、手工、商业及工业业态可能加剧既有风险或引发新风险的区域，此类区域需遵守禁止性规定或合规要求（参见《环境法典》L562-1条款）。该第三类区域仅适用于自然风险预防规划（RPP）。
