Dataset Direct Download Service (WFS): PPRi Essonne — Loiret Regulated 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 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PPRs，《环境法典》（Environmental Code）在其L562-1条款中划定了两类区域：风险暴露区域，以及虽未直接面临风险但可采取预判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. “建筑禁建区”（俗称“红色区域”）：该区域危险等级偏高，通用规则为禁止建设活动；
2. “合规管控区”（俗称“蓝色区域”）：该区域危险等级为中等，建设项目需遵守适配于风险类型的专项要求；
3. 间接风险关联区域：此类区域虽未直接暴露于风险之中，但各类建设工程、开发项目或农业、林业、手工业、商业及工业经营场所均可能加剧既有风险或引发新的风险，因此需遵守相关禁令或管控要求（详见《环境法典》L562-1条款）。该类区域仅适用于自然RPPs。
