Dataset Direct Download Service (WFS): List of technological PPRs in Hérault

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) on the other hand.

风险预防计划（Risk Prevention Plans，简称PPR）由1995年2月2日《加强环境保护法》设立，是国家在风险预防领域的核心管控工具，其目标是对重大风险区域的开发动态进行监测。

PPR由法国省长批准，通常由领土事务省局（DDT）负责推进实施。此类计划通过针对现有或未来建筑的建筑禁令、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调整等），对土地使用与用途布局进行规制。

PPR可处于三种状态：制定中（已发布规制要求）、提前实施或已获批。

PPR文件包含编制说明、监管分区规划与监管条例。其他有助于理解该方案的图形资料（如风险分布图、相关问题梳理等）可作为附件附加。每份PPR通过一个多边形进行标识：若该计划处于制定阶段，该多边形对应规制措施覆盖的市镇范围；若处于获批阶段，则对应受限区域的边界范围。

本地理数据表可用于绘制省内现有PPRT的空间分布图。

地理数据表N_DOCUMENT_PPRT中存储的每份PPRT文档，均与其GASPAR代码相关联，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PPR程序的参考年份与编制序号）：
1. 一方面是其在GASPAR应用系统中管理的编制（或修订）行政流程；
2. 另一方面是其元数据表N_PPRT_AAAANNNN（编号0001496）中描述的全套数字空间数据集。
