PPRN on the department of Val-d'Oise
Description
Risk prevention plans (RPPs) 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 the control of development in areas exposed to a major risk.PRPs are approved by the prefects and generally carried out by the departmental directorates of territories (DDT). These plans regulate land use or use through building prohibitions or requirements on existing or future buildings (constructive provisions, work to reduce vulnerability, restrictions on use or agricultural practices, etc.). These plans may be under development (prescribed), applied in advance or approved.The PPR file contains a presentation note, a regulatory zoning plan and a by-law. Other graphic documents 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 concerned within the scope of prescription when it is in the prescribed state; and the restricted zone envelope when in the approved state. This geographical table allows mapping existing PPRNs on the department.Each PPRN document existing in the geographical table N_DOCUMENT_PPRN is linked using its GASPAR code of format "ddd[PREF|DDT|DDTM|DREAL]AAAANNNN" (AAAA and NNNN correspond to the reference year and the serial number of the PPR procedure associated in GASPAR):1. to its administrative procedure of elaboration (or revision) managed in the GASPAR application, on the one hand,2. to its series of constituent numerical geographical data described by the metadata sheet N_PPRN_AAAANNNN (#0001495) on the other hand.
