Dataset Direct Download Service (WFS): PPRT — PPRT Document on the Department of Meurthe-et-Moselle (54)

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 RPP 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 municipalities 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 makes it possible to map existing PPRTs on the department. Each PPRT document existing in the geographical table N_DOCUMENT_PPRT is linked with its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and the order number of the associated PPR procedure in GASPAR): 1. its administrative procedure for drawing up (or revising) managed in the GASPAR application, on the one hand, 2. its set of numeric spatial data as described in the metadata sheet N_PPRT_AAAANNNN (#0001496).风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日颁布的《加强环境保护法案》确立，是国家在风险预防领域的核心工具，其目标是对存在重大风险区域的开发活动进行监测。 PPR由法国省长批准，通常由领土事务总局（DDT）负责执行。此类计划通过对现有或拟建建筑设定建筑禁令或相关要求（包括建设规定、降低脆弱性工程、农业使用限制或操作规范等），来规范土地利用行为。 此类计划可分为编制（核定）阶段、提前实施及已获批三种状态。 PPR文件包含说明性备忘录、管制区划图与管制条例。其他有助于理解该计划的图文资料（如风险点位、相关议题等）可作为附件附加。每份PPR通过多边形进行标识：当计划处于核定阶段时，该多边形对应纳入管控范围的所有市镇；当计划获批后，则对应受限区域的边界范围。 本地理表格可实现省内现有PPRT的空间制图。 地理表格N_DOCUMENT_PPRT中收录的每份PPRT文件，均与其GASPAR编码相关联，该编码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应关联PPR流程的参考年份与GASPAR系统内的流程序号）： 1. 其一为GASPAR系统中管理的PPRT编制（或修订）行政流程； 2. 其二为元数据表格N_PPRT_AAAANNNN（#0001496）中描述的数值空间数据集。
