Dataset Direct Download Service (WFS): Restricted areas of the plan for the prevention of natural hazards of the municipality of SAINTE-CROIX-VOLVESTRE

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.自然灾害预防计划（Natural Hazard Prevention Plan，简称PPRN）的管控区划已按照COVADIS的国家要求完成数字化转换。针对自然类PPRN，《环境法典》将区划划分为两类（L562-1）：风险暴露区，以及未直接面临风险但可预先采取措施避免风险加剧的区域。根据灾害等级的不同，每类区域均需遵循可强制执行的土地使用与建设管控细则。相关法规通常将区划细分为三类：1. 禁建区（又称"红区"）：灾害等级较高，通用管控规则为全面禁止建设行为；2. 规定管控区（又称"蓝区"）：灾害等级为中等，建设项目需遵循适配风险类型的专属管控要求；3. 未直接面临风险，但建设、工程、开发活动或农业、林业、手工业、商业及工业类经营场所可能加剧既有风险或引发新风险的区域，需遵循相应禁令或管控要求（详见《环境法典》第L562-1条）。此类区划仅适用于自然类RPPs。
