Redistribution of the map with the flood prone areas in Flanders (status 2017-07-13)

This is a redistribution of the data source 'Overstromingsgevoelige gebieden 2017 - (Watertoets), correctie 13/07/2017', originally published by 'Vlaamse Milieumaatschappij - afdeling Operationeel Waterbeheer' and ‘Departement Mobiliteit en Openbare Werken, afdeling Waterbouwkundig Laboratorium’, and distributed by 'Informatie Vlaanderen' under a CC-BY compatible license. It is redistributed for reproducible, analytical workflows on Flemish Natura 2000 habitats and regionally important biotopes.

In the context of the Flemish Water Assay (Watertoets), a fourth version of a map has been created that shows flood prone areas up to the plot level for the entire Flemish Region. The map contains the effectively flood prone areas (‘effectief overstromingsgevoelig’) and the potentially flood prone areas (‘mogelijk overstromingsgevoelig’). 

In this new version, the effectively flood prone areas were processed with information from new and updated modeled flood areas, in addition to the registered local floods between 2006 and now. These modifications honour the changes to the implementing decision that the Flemish Government approved on 15 May 2017. Unlike previous versions that were raster files, the 2017 version is a vector file.

The data source is a coproduction of the Hydraulic Engineering Laboratory of the Department of Mobility and Public Works (Departement Mobiliteit en Openbare Werken, afdeling Waterbouwkundig Laboratorium) and the division Operational Water Management of the Flemish Environmental Agency (Vlaamse Milieumaatschappij - VMM, afdeling Operationeel Waterbeheer), and is owned and administered by the latter.
