Map Viewing Service (WMS) of the dataset: Restricted Areas of the Natural Risk Prevention Plan (NRPP) of Mées — Landes (40)

For Natural Risk Prevention Plans (NPPs), 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.

《环境法典（Environmental Code）》针对自然风险防范计划（Natural Risk Prevention Plans，NPPs）在条款L562-1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通过预先采取措施避免风险加剧的区域。根据危险等级的不同，每类区域均需遵循可强制执行的管控规则。

法规通常将区域划分为三类：
1. “建筑禁止区”，亦称“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. “合规管控区”，亦称“蓝色区域”：该区域危险等级为中等，相关项目需遵循适配具体风险类型的管控要求；
3. 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、商业及工业经营场所均可能加剧既有风险或引发新风险的区域：此类区域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），且该类管控规则仅适用于自然风险防范计划。
