Flood Directive 2007/60/EC — Revision 2020

this map service shows the 2020 revision of the hazard and risk maps of the Flood Risk Management Plan. This revision includes changes resulting from: — Changes made in the context of the variants to the PAI for the modification of the river bands of the Oglio river and the Seveso River (RP field); — changes and updates to the IAP 2 draft proposed by the municipalities in accordance with the procedure referred to in Article 18 of the IAP (RSCM and locally RP scope); — changes to the RSP area proposed by the municipalities in accordance with the procedure referred to in point 3.3.5 of Legislative Decree 6738/2017 and already incorporated in the PGTs; — comments received from those received during the participatory phase of the 2019 revision of the maps. For the changes resulting from some of the comments accepted, given the size of the comments, the Basin Authority has ordered the need for a further three-month participation phase. The details of the changes made to the maps, and the need for a further phase of participation on some of the changes, are described in the decree of the Secretary-General of the Po River District Basin Authority approving the 2020 revision of the maps. The update of the maps concerns: the overall hazard maps (arrigable areas) that constitute a cognitive framework of the IAPs, the overall risk maps (R1, R2, R3, R4) in accordance with Legislative Decree No 49/2010, the hazard and risk maps (floating areas, tie rods, speed, exposed elements) in the APSFRs, which will be reported to the EU Commission.The map service Floods Directive 2007/60/EC — revision 2020, similar to the previous versions (2013, 2015 and 2019) contains the following information layers:PERICOLOSITY — 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 network (RP), hill and mountain secondary hydrographic network (RSCM), lowland secondary hydrographic network (RSP), lacual coastal areas (ACL).RISE — 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.本地图服务展示了《洪水风险管理计划》灾害与风险地图的2020年修订版。本次修订纳入的变更源自以下四类情形： 1. 为修改奥廖河（Oglio River）与塞韦索河（Seveso River）河道带而针对PAI制定的变体方案所引发的变更（RP字段范畴）； 2. 各辖区依据《IAP》第18条规定的程序提出的IAP 2草案修订与更新内容（RSCM及本地RP适用范围）； 3. 各辖区依据2017年第6738/2017号立法令第3.3.5点规定的程序提出的RSP区域变更，该变更已纳入PGTs； 4. 2019年地图修订公众参与阶段收集的意见反馈。针对部分已采纳的意见，鉴于意见体量较大，流域管理局已启动新一轮为期三个月的公众参与程序。 本次地图修订的细节及部分变更需新增公众参与程序的相关说明，均载于波河流域管理局（Po River District Basin Authority）秘书长签发的、批准2020年地图修订的政令中。 本次地图更新涵盖以下内容： 1. 构成IAP认知框架的整体灾害地图（可淹没区域）； 2. 依据2010年第49号立法令制定的整体风险地图（R1、R2、R3、R4）； 3. APSFRs中的灾害与风险地图（淹没区域、拉杆、流速、受影响要素），相关内容将提交欧盟委员会。 本地图服务对应《2007/60/EC洪水指令》2020年修订版，与此前2013、2015及2019版一致，包含以下信息图层： - **危险性（PERICOLOSITY）**：针对三种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地理单元分类：主要水文网（RP）、丘陵与山地次级水文网（RSCM）、平原次级水文网（RSP）、湖泊与沿海区域（ACL）。 - **风险分级（RISE）**：对淹没区内的受影响要素按风险递增程度划分为4个等级，从中度风险R1到极高风险R4。 - **重大潜在风险区（APSFR）**：具有流域及区域级重要性的重大潜在洪水风险区域。
