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.

本数据集按照COVADIS的国家级规范要求，完成了《自然灾害防治计划（Natural Hazard Prevention Plan，PPRN）》合规管控区划的数字化处理。针对自然类自然灾害防治计划，《环境法典（Environmental Code）》第L562-1条将区划划分为两类：直接受风险影响区域，以及虽未直接暴露于风险但可通过预先制定防控措施以规避风险加剧的区域。根据灾害风险等级，每类区域均需遵循强制性管控细则。相关法规通常将区划细分为三类：1. 禁建区（俗称"红区"）：该区域风险等级较高，原则上禁止任何建设活动；2. 管控区（俗称"蓝区"）：该区域风险等级中等，相关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：此类区域虽未直接受风险影响，但各类建设工程、开发活动或农、林、手工业、商业及工业经营场所（含农场）可能加剧既有风险或引发新风险，因此需遵循相应禁令或管控要求（参见《环境法典》第L562-1条）。该类区划仅适用于自然类RPPs。
