Simple download service (Atom) of the dataset: Regulated areas of the plan for the prevention of natural hazards of the municipality of L’AIGUILLON

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《自然灾害预防规划》（Natural Hazard Prevention Plan，PPRN）法定区划的数字化转换工作。 针对自然类自然灾害预防规划，《环境法典》（Environmental Code）将区划划分为两类（条款L562-1）：直接受风险影响区域，以及虽未直接暴露于风险，但可通过预先采取措施避免风险加剧的区域。 根据灾害等级的不同，每类区域均需遵循具有强制执行力的管控规则。相关规范通常将区划划分为三类： 1. **禁止建设区域（又称"红区"）**：此类区域灾害等级较高，原则上禁止任何建设活动； 2. **合规管控区域（又称"蓝区"）**：此类区域灾害等级为中等，建设项目需适配契合具体风险类型的管控要求； 3. 非直接受风险影响区域：此类区域虽未直接暴露于风险，但农业、林业、手工业、商业或工业类的建设、工程、开发活动或农场经营可能加剧既有风险或引发新风险，因此需遵循相应禁止性规定或管控要求（详见《环境法典》条款L562-1）。该类区划仅适用于自然类自然灾害预防规划。
