Map Viewing Service (WMS) of the dataset: Risk — IRPP Regulatory Areas in Loir-and-Cher

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PPR，《环境法典》（Environmental Code）在其L562-1条款中划定两类区域：风险暴露区域，以及虽未直接接触风险但可通过预先制定防控措施避免风险加剧的区域。根据危险等级差异，每类区域均需遵循可强制执行的管控要求。现行法规体系通常将区域划分为三类：1. "禁止建设区"，亦称"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. "特定管控区"，亦称"蓝色区域"：该区域危险等级为中等，区内建设项目需遵循适配风险类型的专项管控要求；3. 非直接风险暴露区域：此类区域虽未直接暴露于风险，但区内开展的建设工程、开发活动、各类农场（涵盖农业、林业、手工业、商业及工业类农场）可能加剧既有风险或引发新风险，因此需遵守相关禁止性规定或管控要求（详见《环境法典》L562-1条款）。该类区域仅适用于自然RPP。
