Map visualisation service (WMS) of the dataset: Documents of the PPRT of Haute-Vienne — departmental assembly

The Risk Prevention Plans (RPPs) were established by the Law of 2 February 1995 on the strengthening of environmental protection. They are the essential tool of the State in the field of risk prevention. Their objective is to control development in areas at major risk. PPRs are approved by the prefects and generally carried out by the Departmental Directorates of Territories (DDT). These plans regulate land use or land use through construction bans 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), applied in advance or approved. The PPR file contains a submission note, a regulatory zoning plan and a regulation. Other graphical documents that are useful for understanding the approach (alases, challenges, etc.) can be attached. Each PPR is spotted by a polygon that corresponds to the set of municipalities concerned with the scope of prescription when it is in the prescribed state; and the envelope of restricted zones 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 geographic table N_DOCUMENT_PPRT is linked using 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 PPR procedure in GASPAR): 1. its administrative procedure for preparing (or revising) managed in the GASPAR application, on the one hand, 2. to its series of numerical constituent geographical data described by the metadata sheet N_PPRT_AAAANNNN (#0001496) on the other hand.
