Map Viewing Service (WMS) of the dataset: Restricted area of the PPRN of the commune of Grand-Village-beach in Charente-Maritime — Forest fires and coastal risks (coastal erosion and marine submersion).

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.针对自然风险防护区域（PPRs），《环境法典》第L562-1条划定了两类区域：风险暴露区域，以及未直接面临风险但可预先采取措施以避免风险加剧的区域。 根据危险等级的不同，每类区域均需遵守具有强制执行力的管控规则。相关法规通常将区域划分为三类： 1. "建筑禁止区域"，又称"红色区域"，该区域危险等级较高，基本原则为禁止一切建设活动； 2. "特定管控区域"，又称"蓝色区域"，该区域危险等级为中等，相关工程需遵守适配问题类型的管控要求； 3. 未直接面临风险，但各类建设工程、开发项目或农、林、手工业、商业及工业经营主体的活动可能加剧既有风险或引发新风险的区域，需遵守相关禁止性规定或管控要求（参见《环境法典》第L562-1条）。该类区域仅适用于自然风险防护区域（RPPs）。
