PPRN — PPR Geographic Data Set Flood — LONGUYON (54322)

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 construction prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on use or agricultural practices, etc.).These plans may be under development (prescribed), implemented in advance or approved.The PPR file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPR is identified by a polygon that corresponds to the set of affected municipalities within the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table allows to map existing PPRNs on the department.风险预防计划（Risk Prevention Plans，PPR）依据1995年2月2日颁布的《加强环境保护法案》制定，是国家在风险预防领域的核心治理工具。其目标为对存在重大风险的区域的开发活动开展监测。PPR由省长批准，通常由领地事务总局（departmental directorates of the territories，DDT）牵头实施。此类计划通过对现有或未来建筑设定建设禁令或相关要求（包括建设规范、减灾工程、使用限制或农业作业约束等），对土地用途及开发活动进行管控。此类计划可处于三种状态：制定中（已下达制定指令）、提前实施或已获批。PPR档案包含说明性报告、管控分区规划及管控条例。此外，可附加有助于理解该计划制定逻辑的其他图文资料（如风险分布图、相关议题梳理文件等）。每份PPR通过多边形进行标识：若处于制定指令阶段，该多边形对应指令覆盖范围内的所有受影响市镇；若处于获批阶段，则对应受限区域的范围包络线。本地理数据表可用于在省内绘制现有PPR的空间分布图。
