Plan for the prevention of natural risks of landslide — Commune de Lafrançaise — Types of risk treated in a multi-risk PPRN — Department of Tarn-et-Garonne

Non-geometric table to be used for multi-hazard RPPs to inform the types of risk addressed in the RPP. Plans for the prevention of natural hazards (PPRN) 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 PPRNs 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 PPRN 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 PPRN 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. Each PPRN document in this geographical table is linked with its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and serial number of the associated PPRN 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 constituent geographic data described in the metadata sheet N_PPRN_AAAANNNN, on the other hand.本非几何表格（Non-geometric table）适用于多危害风险预防计划（RPP, Risk Prevention Plan），用于明确该计划所应对的风险类型。 1995年2月2日颁布的《加强环境保护法》确立了自然危害预防计划（PPRN, Preventive Plans for Natural Hazards），其作为国家风险预防领域的核心工具，目标是对重大风险暴露区域的开发活动实施监测。 此类计划由省长批准，通常由领地部门主管局（DDT, Departmental Directorates of the Territories）负责组织实施。该计划通过针对现有及拟建建筑制定建筑禁令或相关要求（含建设规范、脆弱性降低工程、农业使用限制或耕作规范等），对土地用途实施管控。 此类计划可分为三种状态：已下达编制指令阶段、提前实施阶段以及获批阶段。 PPRN档案包含编制说明、规制性分区规划与规制细则，亦可附加有助于理解该计划编制思路的其他图文资料（如危害分布图、问题梳理材料等）。每份PPRN均通过多边形矢量进行标识：处于已下达编制指令阶段时，该多边形对应指令覆盖范围内的受影响市镇集合；处于获批阶段时，则对应受限区域的范围边界。本地理表格（Geographical table）可用于在省级行政范围内绘制现有PPRN的空间分布图谱。 本地理表格中的每份PPRN文档，均与其GASPAR代码（GASPAR code）相关联，该代码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中关联PPRN编制流程的参考年份与序列号）： 1. 一方面为GASPAR系统中管理的PPRN编制（或修订）行政流程； 2. 另一方面为元数据表单N_PPRN_AAAANNNN中描述的全套组成地理数据。
