The Natural Risk Prevention Plans (PPRNs) were established by the law of 2 February 1995 on strengthening the protection of the environment.
The scheme has been supplemented by the plans for the prevention of mining risks introduced by Law No. 99-245 of 30 March 1999 on liability for damage resulting from the mining; mining and the prevention of mining risks after the end of #x27; exploitation, codified in the new mining code (Article L174-5)
They constitute the essential instrument 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 in progress; development (prescribed), applied in advance or approved.
The PPR file contains a submission note, a regulatory zoning plan and a regulation. Can be attached d' other graphic documents useful for understanding the approach (hazards, challenges...). Each PPR shall be identified by a polygon corresponding to the prescribing perimeter set of municipalities concerned when it is at the prescribed state; and l' envelope of restricted zones when it is at the approved state. This geographical table makes it possible to map existing PPRMs on the department.
Each PPR document in this spatial dataset is linked to the GASPAR code “ddd[PREF|DDT|DDTM|DREAL]aaaanannnn” (AAAA and NNNN correspond to the reference year and order number of the associated PPR procedure in GASPAR):
1. to its administrative procedure; preparation (or revision) managed in the \#x27; GASPAR application, d' on the one hand,
2. its series of spatial constituent data described by metadata sheet N_PPRM_AAAANNNN, d' other.
__Origin__
This dataset is rendered geometrically using the IAL perimeter (prescription perimeter when the PPRM is prescribed or regulated perimeter when the PPRM is approved).
The geometry of the prescribed perimeter of the PPRM is provided by the prefectural prescription order of this PPRM.
The geometry of the regulated perimeter of a PPRM is constructed by the geometric aggregation of the polygons representing the zones restricted by the PPRM.
