Map Viewing Service (WMS) of the dataset: Restricted areas of the plan for the prevention of natural hazards of the municipality of Sinsat

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.

本自然灾害预防计划（Natural Hazard Prevention Plan，缩写PPRN）的合规区划已依据COVADIS的国家规范完成数字化处理。
针对自然类灾害预防计划，《环境法典》（Environmental Code）第L562-1条将区划划分为两类：受灾害直接影响区域，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。
根据灾害等级差异，各区域需遵循可强制执行的处置规则。现行法规通常将区划细分为三类：
1. 禁建区（俗称‘红色区域’）：此类区域灾害等级较高，通用规则为全面禁止建筑活动；
2. 管制建设区（俗称‘蓝色区域’）：此类区域灾害等级中等，相关建设项目需遵循适配风险类型的专项合规要求；
3. 间接风险区域：此类区域虽未直接暴露于灾害风险，但任何建筑、工程、开发活动或农、林、手工业、商业及工业类经营场所均可能加剧既有风险或引发新风险，需遵守相应禁止条款或合规要求（详见《环境法典》第L562-1条）。该类区划仅适用于自然类灾害预防计划（RPPs）。
