Simple download service (Atom) of the dataset: Regulated areas of the plan for the prevention of natural hazards of the municipality of Vernajoul

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.

本数据集依据COVADIS的国家规范，完成了《自然灾害防治计划（PPRN）》中合规区划的数字化转化工作。针对自然类PPRN，《环境法典》在L562-1条款中划定了两类基础区域：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。
根据风险等级的不同，各区域均需遵循可强制执行的管控规则。相关法规通常将区域划分为三类：
1. 「禁止建设区」（又称「红色区域」）：该区域风险等级较高，通用规则为禁止任何建设活动；
2. 「合规建设区」（又称「蓝色区域」）：该区域风险等级中等，建设项目需遵循适配问题类型的专项管控要求；
3. 虽未直接面临风险，但建设工程、开发活动或农业、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的区域，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）。该类区域仅适用于自然类RPPs。
