Map Viewing Service (WMS) 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.

自然风险防治规划（Natural Hazard Prevention Plan，PPRN）的合规区划已按照COVADIS的国家相关要求完成数字化。针对自然风险防治规划，《环境法典》（L562-1条款）划定了两类区划：一类为风险暴露区，另一类为未直接面临风险但可采取措施避免风险加剧的区域。依据风险等级的不同，每类区划均需遵守可强制执行的管控规则。相关监管规则通常将区划细分为三类：1. 建筑禁建区（又称"红区"）：此类区域风险等级较高，通用管控规则为禁止任何建设活动；2. 指定管控区（又称"蓝区"）：此类区域风险等级为中等，相关建设项目需符合适配于风险类型的管控要求；3. 未直接面临风险，但农业、林业、手工业、商业或工业类建筑、工程、开发项目或农场可能加剧既有风险或引发新风险的区域：该类区域需遵守禁令或管控要求（参见《环境法典》L562-1条）。且该类区划仅适用于自然风险防治规划。
