Table listing flood risk maps produced on a given IRR.

A series of geographical data produced by the GIS Flooding Directive of the territory of significant risk of flooding (TRI) of Mayotte and mapped for reporting purposes for the European Flood Directive. 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 a flood risk management plan aimed at reducing the negative consequences of flooding on human health, the environment, cultural heritage and economic activity. The objectives and requirements for achievement are given by the Law of 12 July 2010 on the National Commitment for the Environment (LENE) and the Decree of 2 March 2011. Within this framework, the primary objective of the mapping of flood areas and flood risks for IRRs is to contribute, by homogenising and objecting knowledge of the exposure of issues to floods, to the development of Flood Risk Management Plans (IFMPs). This dataset is used to produce flood surface maps and flood risk maps that represent flood hazards and issues on an appropriate scale, respectively. Their objective is to provide quantitative elements to assess the vulnerability of a territory more accurately for the three levels of flood probability (high, medium, low).
