data consultation service (WMS) from: Low coastal areas at risk of marine submersion

This map reproduces the map at 1/25 000 annexed to the Prefect’s letter of 18 December 2013 and allows an extension to 1/2000. This map cancels and replaces the low area maps broadcast in January 2011. Note: The regulatory zoning of the West-Odet and East-Odet PPRLs approved on 12/07/2016 replaces the 2013 hazard zones on this mapping. Definitions: NMR: The Marine Reference Level corresponds to the Centennal Marin Level (NMC) increased by 20 cm to take into account the effects of climate change. NMC: The Marin Centennal level was defined according to the methodological note of 22 January 2013 on the studies “Statistics of extreme marine levels of the coasts of France” published in 2008 and 2012 by the SHOM/CETMEF. Hazard zones areas of hazard ‘fort’ areas located more than 1 m below the Marine Reference Level (NMR) ‘medium’ hazard areas areas between 0 and 1 m below the Marine Reference Level (NMR) ‘climate-related’ hazard areas areas between 0 and 40 cm above the Marine Reference Level (NMR) ZDE: Energy Dissipation Zone (100 m) at the back of known protection systems (digues or dune cords) c_Zone_de_dissipation_d_energie_100m c_limite_communale_ Tags C_limite_communale C_Zonage_PPRSM_PPRL_Values_l_cartelie c_zones_basses_dpt29_colors_Values_H_eau
