Flood Directive 2007/60/EC — Revision 2019

this map service shows the 2019 revision (first revision under Article 14 of Directive 2007/60/EC) of the hazard and risk maps of the Flood Risk Management Plan. The Permanent Institutional Conference took note of this revision at its meeting on 20 December 2019. The update of the maps concerns: the total hazard maps (arrigable areas) that constitute a cognitive framework of the PAIs; the overall risk maps (R1, R2, R3, R4), in accordance with Legislative Decree No 49/2010, and the hazard and risk maps (floating areas, tie rods, speed, exposed elements) in the APSFRs, which will be reported to the EU Commission. The Floods Directive map service 2007/60/EC — revision 2019, similar to the previous versions (2013 and 2015) contains the following information layers: Hazards — Delimitation of areas potentially affected by floods for three flood scenarios: frequent H (TR 20-50 years), infrequent M (TR 100-200 years) and rare L (TR up to 500 years). The areas are identified for different territorial areas: main hydrographic grid (RP), hill and mountain secondary hydrographic grid (RSCM), lowland secondary hydrographic grid (RSP), coastal lake areas (ACL). Risk — Classification of exposed elements falling within floodable areas according to 4 degrees of increasing risk from moderate R1 to very high R4. APSFR — Areas with potential significant risk of district and regional importance. The changes made to the maps of floodable areas in the Lombardy Region are described in the document annexed to this metadata, which also shows the data sources used to update the elements presented in the risk maps. The same document also shows the list of Areas with Potential Significant Risk (APSFR) identified on the territory of the Lombardy Region with the comparison with the Areas of Significant Risk (ARS) identified in the 2015 PGRA.本地图服务展示了《洪水风险管理计划》（Flood Risk Management Plan）的灾害与风险地图2019年修订版——该修订为依据《2007/60/EC指令》第14条完成的首次修订。常设机构会议于2019年12月20日的会议上审议通过了此次修订。 此次地图更新涵盖以下内容：构成潜在受影响区域（PAIs，Potentially Affected Areas）认知框架的全域灾害地图（可淹没区域）；依据2010年第49号立法法令要求编制的全域风险地图（R1、R2、R3、R4）；以及具有区级及以上潜在重大风险的区域（APSFR，Areas with Potential Significant Risk of district and regional importance）内的灾害与风险地图（漂浮区域、系杆、流速、暴露元素），上述内容将上报至欧盟委员会。 《2007/60/EC洪水指令》地图服务2019年修订版，与此前2013、2015版本一脉相承，包含以下信息图层： 1. 灾害图层：针对三类洪水情景划定潜在受淹区域：高频情景H（重现期20-50年）、中频情景M（重现期100-200年）及低频情景L（重现期最高500年）。上述区域按不同水文分区划分：主干水文网格（RP，main hydrographic grid）、丘陵与山地次级水文网格（RSCM，hill and mountain secondary hydrographic grid）、低地次级水文网格（RSP，lowland secondary hydrographic grid）、沿海湖泊区域（ACL，coastal lake areas）。 2. 风险图层：依据四级递增风险等级（从中度R1至极高R4），对淹没区域内的暴露元素进行分类定级。 3. APSFR：指具有区级及区级以上潜在重大洪水风险的区域。 伦巴第大区境内淹没区域地图的变更细节，已在本元数据附带的文档中予以说明，该文档同时列明了用于更新风险地图相关要素的数据源。此外，该文档还列出了在伦巴第大区境内识别出的具有潜在重大风险的区域（APSFR）清单，并与2015年PGRA计划（Programma di Gestione del Rischio Alluvioni，即洪水风险管理计划）中识别出的重大风险区域（ARS，Areas of Significant Risk）清单进行了对比。
