Simple download service (Atom) of the dataset: Regulatory zoning of the Flood Risk Prevention Plan (PPRI) in the municipality of Saint Raphael (Var)

The Risk Prevention Plans (P.P.R) codified in Articles L562-1 to L562-7 and R562-1 et seq. of the Environmental Code, relating to the prevention of foreseeable natural hazards, the implementation of which is governed by Decree No 95-1089 of 5 October 1995, constitute one of the tools for the implementation of the State policy on flood prevention, which was redefined in the Interministerial Committee of 24 January 1994. This legislative and regulatory framework was supplemented by the law of 30 July 2003 (later on the date of approval of the Saint-Raphaël PPRI). The Plan for the Prevention of Natural Flood Risks in the commune of Saint Raphael, linked to the presence of the rivers Garonne, Peyron, Pédegal and Agay, was approved by prefectural decree of 20 November 2000. A regulation shall apply referring to prohibition and/or prescription measures depending on the different mapped areas. Two hydraulic studies were used as the basis for the definition of hazard: (one conducted on the Garonne, Peyron and Pédégal basins in 1996 and corrected in 1998), the other conducted on the Agay River watershed in 1996). As a result, a paper-based mapping was provided. This hazard allowed, following the application of a constructibility grid, to determine a digitalised regulatory zoning that was reported on a background IGN1998©EDR 25. A separate mapinfo table existed for each type of zoning: R1, R2, B1 and B2. These 4 tables were then merged to create a single table.风险预防计划（Risk Prevention Plans, P.P.R）的编纂依据为《环境法典》第L562-1条至L562-7条以及R562-1条及后续条款，旨在防控可预见的自然灾害，其实施由1995年10月5日第95-1089号政令监管。该计划是1994年1月24日部际委员会重新界定的国家防洪政策的实施工具之一。 该立法与监管框架由2003年7月30日颁布的法律予以补充，该法律的施行时间晚于圣拉菲尔洪水风险预防计划（PPRI）的获批日期。 涉及加龙河（Garonne）、佩龙河（Peyron）、佩德加尔河（Pédegal）与阿盖河（Agay）的圣拉菲尔市镇自然洪水风险预防计划，于2000年11月20日经省长政令获批。 针对不同的测绘分区，将适用包含禁止性及/或规定性措施的监管规则。 两项水文水利研究被用作洪水风险划定的基础：其一于1996年针对加龙河、佩龙河与佩德加尔河流域开展，并于1998年完成修正；其二于1996年针对阿盖河流域开展。基于上述研究，生成了纸质版风险测绘图。通过应用可建性网格对该风险数据进行处理，可确定数字化监管分区，该分区以法国国家地理研究院（Institut Géographique National, IGN）1998年版©EDR 25为底图。每一类分区（R1、R2、B1与B2）均对应独立的MapInfo表格，随后将这4张表格合并为一张总表。
