Restricted areas of the plan for the prevention of natural hazards of the municipality of Montferrier

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的国家相关规范，完成了自然灾害预防规划（Natural Hazard Prevention Plan, PPRN）管制区划的数字化工作。针对自然类PPRN，《环境法典》将其管制区划分为两类（L562-1条款）：直接受风险影响区域，以及虽未直接暴露于风险但可采取防控措施避免风险加剧的区域。依据灾害等级的不同，各区域需遵守强制性建设管控要求。相关规范通常将区划划分为三类：1. ‘禁止建设区’（亦称‘红色区域’）：该区域灾害等级较高，通用管控规则为禁止一切建设活动；2. ‘限制建设区’（亦称‘蓝色区域’）：该区域灾害等级中等，建设项目需遵循适配风险类型的管控要求；3. 虽未直接暴露于风险，但建设工程、开发活动或农林牧渔、手工业、商业及工业业态可能加剧既有风险或引发新风险的区域，需遵守建设禁令或相关管控要求（详见《环境法典》L562-1条款）。该类区划仅适用于自然类RPPs。
