PPRN document on the Côtes d'Armor department

Risk prevention plans (PPR) were established by the Act of 2 February 1995 on the strengthening of environmental protection. They are the essential instrument of the State in terms of risk prevention. Their objective is to control 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 use by prohibiting construction or prescribing existing or future buildings (constructive arrangements, work to reduce vulnerability, restrictions on use or agricultural practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The PPR file contains a cover note, a regulatory zoning plan and a by-law. Other graphical documents that are useful for understanding the approach (hazards, issues, etc.) may be attached. Each PPR is identified by a polygon that corresponds to the set of municipalities affected by the limitation period when it is in the prescribed state; and the envelope of restricted zones when it is in an approved state. This geographical table makes it possible to map the PPRN existing on the department. Each PPRN document existing in the geographical table N_DOCUMENT_PPRN is linked using its GASPAR code in the format ‘dd[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 preparation (or revision) procedure managed in the GASPAR application, on the one hand, 2. its set of constituent numerical spatial data described by the metadata sheet N_PPRN_AAAANNNN (#0001495) on the other hand.
