Map visualisation service (WMS) of the dataset: PPR ARROS-DE-NAY (64DDTM20010002) — Information area of a risk prevention plan Flooding of ARROS-DE-NAY (64054), department of Pyrénées-Atlantiques.

The plans for the prevention of natural hazards (PPRn) were established by the law of 2 February 1995 on the strengthening of the protection of the environment. They are the essential tool 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 PPRn are decided by the prefects and usually carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use by prohibitions of construction or requirements on existing or future buildings (constructive provisions, work to reduce vulnerability, (restrictions on use or agricultural practices...). These plans may be under development (prescribed), applied in advance or approved. Expert information makes it possible to shed light on the expertise conducted within the framework of the PPRn by specifying particular points (fracking zone, obstacle such as a bridge,...) or by adding information useful to the general understanding of the PPRn (benchmarks of flood, direction of flow, flow velocity, etc.).
