PPRN document on the Deux-Sèvres department
Description
The Risk Prevention Plans (RPPs) were introduced by the Act of 2 February 1995 on the strengthening of environmental protection. They are the State’s key instrument for risk prevention. Their objective is to control development in areas exposed to major risk.PPRs are approved by the prefects and generally carried out by the Departmental Directorates of the Territories (DDT). These plans regulate land use or its use through building bans or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on use or agricultural practices...).These plans may be under preparation (prescribed), applied in advance or approved.The PPR file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (hazardous, stakes, etc.) may be attached. Each PPR is identified by a polygon that corresponds to the set of municipalities concerned in the scope of prescription when it is in the prescribed state; and the envelope of the restricted areas when it is in the approved state. Each existing PPRN document in the geographical table N_DOCUMENT_PPRN is linked using its GASPAR code in the format “ddd[PREF|DDT|DDTMDREAL]aaannn” (AAAA and NNNN correspond to the reference year and the order number of the associated PPR procedure in GASPAR): 1. its administrative procedure for the development (or revision) managed in the GASPAR application, on the one hand, and 2. its set of constituent digital geographical data described in the metadata sheet N_PPRN_AAAANNNN (#0001495) on the other hand.
