Dataset Direct Download Service (WFS): Regulatory zoning of the Flood Risk Prevention Plan (PPRI) of Golo, Asco and Tartagine in Upper Corsica

Plans for the prevention of natural hazards were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor the development of urban planning and land use in areas at risk.
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.

This PPRI concerns the Golo, Asco and Tartagine watersheds.

1995年2月2日颁布的《加强环境保护法案》确立了自然灾害防治规划，该规划是国家在风险防治领域的核心工具，其目标是对风险区域内的城市规划与土地利用开发情况进行监测。
针对自然灾害防治规划（Natural PPRs），《环境法典》第L562-1条将区域划分为两类：受风险影响区域，以及未直接面临风险但可采取措施避免风险加剧的区域。
根据灾害等级不同，各区域需遵守可强制执行的整治要求。相关法规通常将区域划分为三类：
1. "建筑禁建区"，亦称"红色区域"，此类区域灾害等级较高，原则上禁止任何建设活动；
2. "规制建设区"，亦称"蓝色区域"，此类区域灾害等级中等，建设项目需符合适配风险类型的相关要求；
3. 未直接暴露于风险之中的区域，但该区域内的建设工程、施工项目、开发活动或农场、农业、林业、手工业、商业及工业类经营活动可能加剧既有风险或引发新的风险，因此需遵守相关禁令或要求（详见《环境法典》第L562-1条）。该分类仅适用于自然灾害防治规划（Natural RPPs）。
本次自然灾害防治规划（PPRI）涉及戈洛河、阿斯科河与塔尔塔吉涅河流域。
