Dataset Direct Download Service (WFS): IRPP Restricted Area in the PORTO Watershed

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). These zones are referred to as “non-hazardous prescribing zones” and are of sky blue colour.

针对自然PPRs，《环境法典》（Environmental Code）第L562-1条将区域划分为两类：风险暴露区，以及虽未直接面临风险但可提前采取相关措施以避免风险加剧的区域。依据危险等级的差异，每类区域均需遵循可强制执行的管控规范。相关法规通常将区域划分为三类：1. 建筑禁止区（俗称"红色区域"）：该区域危险等级较高，原则上禁止一切建设行为；2. 规定管控区（俗称"蓝色区域"）：该区域危险等级为中等，相关项目需遵循适配问题类型的管控要求；3. 非直接风险暴露管控区：该区域虽未直接面临风险，但任何建设、工程、开发活动，或农业、林业、手工业、商业及工业类农场均可能加剧现有风险或引发新风险，因此需遵守相关禁令或管控要求（参见《环境法典》第L562-1条）。此类区域被称为"无危险规定区"，配色为天蓝色。
