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

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的国家规范要求，完成了《自然灾害防治规划（Natural Hazard Prevention Plan，简称PPRN）》中合规管控区划的数字化工作。针对自然风险类PPRN，《环境法典》在L562-1条款中定义了两类区划：风险暴露区，以及未直接面临风险但可采取措施规避风险加剧的区域。依据灾害等级差异，每类区划均需遵循可强制执行的建设管控规则。相关监管规范通常划分出三类区划：1. 禁止建设区（又称"红区"）：此类区域灾害等级较高，通用管控规则为禁止所有建设行为；2. 合规建设区（又称"蓝区"）：此类区域灾害等级中等，建设项目需落实适配问题类型的专属管控要求；3. 未直接面临风险，但建设活动、工程作业、开发项目或农林牧渔、手工业、商业、工业经营等行为可能加剧既有风险或引发新风险的区域，需遵守相关禁令或管控要求（详见《环境法典》L562-1条款）。该类区划仅适用于自然风险类RPPs。
