Regulatory zones of PPRI 2013 Dordogne and tributaries to Hautefage — Corrèze

Plans for the prevention of natural flood risk PPRI of the Dordogne basin and its tributaries of Argentat in Liourdres (15 communes) in Corrèze

Natural PPRs are established in accordance with Article L. 562-1 of the Environmental Code. In exposed areas, depending on the intensity of the risk, they shall define the prohibition zones for constructions and installations in order not to aggravate the risk, or, in areas where constructions and installations may be authorised, the implementation requirements.

The PPRi of the Dordogne basin and its tributaries from Argentat to Liourdres, approved on 30/10/2013, cover 15 municipalities (one PPRi per municipality). The rivers concerned are Dordogne, Maronne, Souvigne and Sagne and Filèle, Malefarge, Ménoire and Cerou. The hazard is derived from a modeling. The reference flood is the strongest history known for Souvigne, Sagne and Fidèle (crue of October 1960) and the centennial flood calculated for Dordogne, Maronne, Malefarge, Ménoire and Céroux. The purpose of the regulations is to prevent the risk to people and property. For this purpose, the flood-free territory is classified as red (inconstructible), dark blue (constructable under conditions for economic activities) or blue (constructible under conditions)

A PPRi is established for each municipality, i.e.: Argentat-sur-Dordogne, Hautefage, La-Chapelle-Saint-Géraud, Forgès, Saint-Chamant, Monceaux-sur-Dordogne, Bassignac-le-Bas, Reygades, Chenaillers-Mascheix, Brivezac (merged with Beaulieu-sur-Dordogne), Beaulieu-sur-Dordogne, Nonards, Altillac, Astaillac and Liourdres.

2013年多尔多涅河及奥特法热支流自然洪水风险预防计划（PPRI）监管区域——科雷兹省
本数据集对应科雷兹省利乌尔德尔地区阿尔让塔河段支流及多尔多涅河流域的PPRI，覆盖15个市镇。
自然洪水风险预防计划的制定需符合《环境法典》第L.562-1条之规定。在风险暴露区域，将根据风险强度划定建设与设施禁止区域，以避免加剧洪涝风险；对于可获批建设与设施的区域，则需明确实施要求。
本次阿尔让塔至利乌尔德尔河段支流及多尔多涅河流域的PPRI于2013年10月30日获批，覆盖15个市镇（每个市镇对应一份PPRI）。涉及的河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马尔法尔热河、梅努瓦尔河与塞鲁河。本次洪涝风险基于模型推演得出。参考洪水标准为：苏维涅河、萨涅河与菲莱尔河采用有记录以来最强历史洪水（1960年10月洪灾），多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河与塞鲁河则采用百年一遇计算洪水。本监管规则的目的是防范洪涝风险对人员与财产造成的威胁。据此，无洪涝风险区域被划分为三类：红色区域（不可建设）、深蓝色区域（符合条件可开展经济活动类建设）及蓝色区域（符合条件可建设）。
本次覆盖的15个市镇均单独制定了PPRI，分别为：阿尔让塔河畔多尔多涅、奥特法热、拉沙佩勒-圣热罗、福尔热、圣尚、多尔多涅河畔蒙索、下巴桑尼亚克、雷加德、谢奈耶-马斯谢、布里夫扎克（已与多尔多涅河畔博略合并）、多尔多涅河畔博略、诺纳尔、阿尔蒂亚克、阿斯泰亚克及利乌尔德尔。
