Dataset Direct Download Service (WFS): Restricted areas of the plan for the prevention of natural hazards of the commune of SURBA

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《自然灾害防治规划（Natural Hazard Prevention Plan，PPRN）》中管制区划的数字化处理。
针对天然灾害类PPRN，《环境法典（Environmental Code）》第L562-1条将区划分为两类：风险暴露区，以及虽未直接面临风险但可预先采取措施避免风险加剧的区域。
依据灾害等级，各区域需遵循可强制执行的管控规则。相关管控规则通常将区划分为三类：
1. "建筑禁建区"（又称"红色区域"）：该区域灾害等级较高，通用规则为禁止建设；
2. "管制建设区"（又称"蓝色区域"）：该区域灾害等级为中等，建设项目需遵循适配问题类型的相关要求；
3. 虽未直接面临风险，但任何建筑、工程、开发活动或农业、林业、手工业、商业及工业类场所均可能加剧风险或引发新风险的区域：此类区域需遵循禁建或特定管控要求（详见《环境法典》第L562-1条）。此类区划仅适用于天然灾害类RPPs。
