Flood directive, Isolate area height class of the IRR of the island of Cayenne, 2015

*** PROVISIONAL DATA, PB TOPOLOGICAL QUALITY *** An area for which a hazard of a certain type under a certain scenario causes a rise of water whose height is within a fixed range of values. A height class iso area is an area for which all water heights are within the same height range. A height class iso area is characterised by its spatial extension and the minimum and maximum terminals of the height range. Data sets produced by the GIS Flooding Directive at significant risk of flooding (TRI) of the island of Cayenne and mapping for reporting purposes for the European Flood Directive. The European Directive 2007/60/EC of 23 October 2007 on the assessment and management of flood risks (OJ L 288, 06-11-2007, p. 27) influences the flood prevention strategy in Europe. It requires the production of flood risk management plans aimed at reducing the negative consequences of flooding on human health, the environment, cultural heritage and economic activity. The objectives and requirements for realignment are given by the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. In this context, the primary objective of the mapping of flood areas and flood risks for IRRs is to contribute, by homogehising and objecting knowledge of the exposure of issues to floods, to the development of flood risk management plans (FRPs).
