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

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.

本数据集将依据COVADIS的国家规范，对自然灾害防治规划（Natural Hazard Prevention Plan，简称PPRN）的合规区划进行数字化处理。
针对自然类PPRN，《环境法典（Environmental Code）》第L562-1条将区划划分为两类：受风险影响区域，以及虽未直接面临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，每类区域均需遵循可强制执行的建设管控规则。法规通常将区划细分为三类：
1. "禁建区域"，又称"红色区域"：此类区域灾害等级较高，通用规则为禁止建设；
2. "合规建设区域"，又称"蓝色区域"：此类区域灾害等级为中等，建设项目需遵循适配问题类型的管控要求；
3. 虽未直接面临风险，但各类建设工程、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，需遵守禁建或管控要求（参见《环境法典》第L562-1条）。此类区划仅适用于自然类RPPs。
