Map Viewing Service (WMS) of the data batch: Upstream Vienna Flood Risk Prevention Plan (PRIP) — Availles-Limouzine/Valdivian section

The Risk Prevention Plans (PPR) 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 development in areas exposed to a major risk. The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through building prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The upstream Vienna PPRI — Availles-Limouzine/Valdivienne section was approved by prefectural order on 24 December 2009.风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日颁布的《加强环境保护法》确立，是国家风险预防领域的核心治理工具。其目标为监测存在重大风险区域的开发活动。此类计划由省长审批，通常由省领土事务总局（departmental directorates of the territories，DDT）负责实施。计划通过对现有或未来建筑设置建筑禁令或提出建设要求（涵盖建设规范、脆弱性降低工程、农业用途或耕作限制等），对土地利用进行规制。此类计划可分为三种状态：编制阶段（法定编制）、提前实施以及已获批。上游维也纳PPRI——阿瓦耶-利穆济讷/瓦尔迪维耶讷区段于2009年12月24日经省长令正式获批。
