Map Viewing Service (WMS) of the dataset: PPRI hazard zone of the catchment areas of Favone, Cannella, Tarcu, Cicolellu, Tafunata — municipalities of Conca and Sari-Solenzara

In the area exposed to one or more hazards represented on the hazard map used for the risk analysis of the PPRI in the watersheds of Favone, Cannella, Tarcu, Cicolellu, Tafunata, a grid of points makes it possible to know at each point the NGF coast of the highest waters for the reference flood. The hazard map (associated point grid) is the result of the flood risk study carried out by SUEZ-SAFEGE in May 2021 as part of the revision of the PPRIs of the Favone and Cannella watersheds approved on 22/04/2002 and the PPRi of the Tarcu, Cicolellu and Tafunata watersheds approved on 08/11/2001. This revision brings together the 2 PPRi into one. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity. All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure). Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards.
