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

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.

本自然灾害防治规划（Natural Hazard Prevention Plan，以下简称PPRN）的合规区划已依据COVADIS的国家规范要求完成数字化处理。针对自然类PPRs规划，法国《环境法典》第L562-1条将区划划分为两类：直接受风险影响的区域，以及虽未直接暴露于风险但可通过预先采取措施规避风险加剧的区域。依据灾害等级的不同，每类区域均需遵循可强制执行的管控规则。相关法规通常将区划分为三类：1. "禁止建设区域"，俗称"红色区域"：该区域灾害等级较高，通用规则为全面禁止建设活动；2. "受限建设区域"，俗称"蓝色区域"：该区域灾害等级为中等，建设项目需遵循适配风险类型的专项管控要求；3. 非直接风险暴露区域：该区域虽未直接承受风险，但各类建设工程、开发活动、农林牧渔经营场地、手工业、商业及工业项目可能加剧既有风险或引发新风险，需遵守相应禁止性规定或管控要求（详见《环境法典》第L562-1条）。此类区划仅适用于自然类RPPs规划。
