PPR USTARITZ (64DDTM20160012) — Information Area of a Ustaritz Flood Prevention Plan (64547), Pyrenees-Atlantiques

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. The objective of this procedure is to monitor development in areas exposed to a major risk. The PPRNs are decided by the prefects and usually carried out by the departmental directorates of the territories (DDT). These plans regulate land use or use through prohibitions on construction or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The expert information helps to shed light on the expertise conducted within the framework of the PPRN by specifying particular points (fracturing zone, obstacle like a bridge,...) or by adding useful information to the general understanding of the PPRN (e.g. flood markers, flow direction, flow velocity, etc.)
