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

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，已完成自然灾害防治规划（Natural Hazard Prevention Plan，PPRN）管控区划的数字化转换。针对自然风险防治规划（Natural Hazard Prevention Plan，PPRs），《环境法典》将其区划划分为两类（第L562-1条）：风险暴露区，以及未直接承受风险但可采取措施避免风险加剧的区域。根据灾害等级差异，每类区域均需遵守可强制执行的建设管控规则。现行法规通常将区划划分为三类：1. 「禁止建设区」（又称「红色区域」）：此类区域灾害等级较高，原则上禁止开展任何建设活动；2. 「管控建设区」（又称「蓝色区域」）：此类区域灾害等级为中等，建设项目需符合适配问题类型的专项管控要求；3. 未直接承受风险，但建设、工程、开发活动或农林牧渔、手工业、商业、工业项目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（参见《环境法典》第L562-1条）。该类区划仅适用于自然风险防治规划（Natural Hazard Prevention Plan，RPPs）。
