Map Viewing Service (WMS) of the dataset: Restricted areas of the plan for the prevention of natural hazards of the municipality of BOMPAS

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，已完成自然灾害防治计划（Natural Hazard Prevention Plan，PPRN）合规区划的数字化转换工作。
针对自然型PPRN，《环境法典》（Environmental Code）第L562-1条将区划划分为两类：风险暴露区，以及虽未直接面临风险但可通过预先制定管控措施规避风险加剧的区域。
依据灾害等级，各区域均需遵守可强制执行的管控规则。相关法规通常将区划分为三类：
1. “禁止建设区”（又称“红色区域”）：灾害等级为高，通用规则为禁止任何建设行为；
2. “规划管控区”（又称“蓝色区域”）：灾害等级为中等，建设项目需遵循适配问题类型的管控要求；
3. 非直接风险暴露区：该区域虽未直接面临风险，但各类建设工程、开发活动或农林牧渔、手工业、商业及工业经营行为可能加剧既有风险或引发新风险，需遵守相关禁止性规定或管控要求（详见《环境法典》第L562-1条）。此类区划仅适用于自然型RPPs。
