Simple download service (Atom) of the dataset: Multi-hazard RPPs of risk types treated in the Lower Fields of Southern Bay Somme PPRN

Hazard synthesis used to describe multi-random areas in the case of multi-hazard PPRN. This data is complementary to the hazard zone of the PPRN of Marquenterre Baie de Somme. Plans for the prevention of natural hazards (PPRN) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to control development in areas exposed to a major risk. PPRNs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through construction prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on use or agricultural practices, etc.).These plans may be under development (prescribed), implemented in advance or approved.The PPRN file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPRN is identified by a polygon that corresponds to the set of affected municipalities within the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table allows mapping existing PPRNs on the department. Each PPRN document existing in this geographical table is linked with its GASPAR code of “ddd[PREF|DDT|DDT|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and serial number of the associated PPRN procedure in GASPAR): 1. its administrative procedure for drafting (or revision) managed in the GASPAR application, on the one hand, 2. its set of constituent geographical data described in the metadata sheet N_PPRN_AAAANNNN, on the other hand.
