Dataset Direct Download Service (WFS): Regulated areas of the plan for the prevention of natural hazards of the municipality of USTOU

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.

自然风险预防计划（Natural Hazard Prevention Plan，缩写PPRN）的合规区划已依据COVADIS的国家相关要求完成数字化处理。针对自然风险预防计划，《环境法典》（Environmental Code）将区划分为两类（条款编号L562-1）：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以规避风险加剧的区域。根据风险等级的不同，每类区域均需遵循可强制执行的管控细则。相关法规通常将区划细分为三类：1. 建筑禁建区（俗称"红区"）：该区域风险等级较高，通用管控规则为禁止任何建设活动；2. 合规管控区（俗称"蓝区"）：该区域风险等级为中等，相关工程建设需遵循适配具体风险类型的管控要求；3. 非直接受风险影响区域：该区域虽未直接暴露于风险，但任何建设、工程、开发项目或农业、林业、手工业、商业及工业类经营活动或场所均可能加剧既有风险或引发新的风险，需遵循相关禁令或管控要求（详见《环境法典》第L562-1条）。该类区划仅适用于自然RPPs。
