Map Viewing Service (WMS) of the dataset: Restricted areas of the plan for the prevention of natural hazards of the commune of CHATEAU-VERDUN

The regulated zoning of the Natural Hazard Prevention Plan (PPRN) is digitised in accordance with the national requirements of COVADIS.
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.

本自然风险预防规划（Natural Hazard Prevention Plan，PPRN）的合规区划已依据COVADIS的国家要求完成数字化处理。针对自然类PPRN，《环境法典》（Environmental Code）在条款L562-1中划定了两类区域：直接受风险影响区域，以及虽未直接暴露于风险但可通过前置管控措施规避风险加剧的区域。根据风险等级差异，每类区域均需遵循可强制执行的建设管控规则。现行法规通常将区划细分为三类：1. 禁止建设区（俗称"红区"）：该区域风险等级较高，通用规则为禁止一切建设行为；2. 合规建设区（俗称"蓝区"）：该区域风险等级为中等，建设项目需适配与风险类型相符的管控要求；3. 间接风险关联区：该区域未直接暴露于风险，但各类建设工程、开发活动，或是农业、林业、手工业、商业及工业类经营场所可能加剧既有风险或引发新风险，因此需遵守相应禁止性规定或管控要求（详见《环境法典》条款L562-1）。此类管控范畴仅适用于自然类RPPs。
