Non-geometric table to be used for multi-hazard PPRs for PPRT North Amiens

The plans for the prevention of technological risks (PPRT) 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. PPRTs 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 PPRT 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 PPRT 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 to map existing PPRTs on the department. Each PPRT document existing in this geographical table is linked with its GASPAR code of format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and serial number of the associated PPRT procedure in GASPAR): 1. its administrative procedure for the preparation (or revision) managed in the GASPAR application, on the one hand, 2. its set of constituent spatial data as described in the metadata sheet N_PPRT_AAAANNNN, on the other hand.
