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

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.

本数据集依据COVADIS的国家级规范要求，对自然灾害预防计划（Natural Hazard Prevention Plan，以下简称PPRN）的合规管控区划完成数字化转换。针对自然类PPRN，《环境法典》（Environmental Code）在条款L562-1中将管控区划分为两类：风险暴露区域，以及非直接暴露于风险但可采取措施规避风险加剧的区域。依据风险等级差异，每类区域均需执行可强制执行的开发建设管控要求。相关管控规则通常将区划划分为三类：1. 建筑禁建区（又称“红色区域”）：该区域风险等级为高，通用管控准则为禁止任何建设活动；2. 指定管控区（又称“蓝色区域”）：该区域风险等级为中等，建设项目需适配对应风险类型的专项管控要求；3. 非直接暴露于风险，但各类建设、工程、开发活动或农业、林业、手工业、商业及工业经营主体可能加剧既有风险或引发全新风险的区域，需遵守相关禁止性规定或管控要求（详见《环境法典》条款L562-1）。该第三类区划仅适用于自然类RPPs。
