For each address in Linz, we check whether it lies inside a flood area of the official flood maps. The maps mark three areas. The 30-year (HQ30) and the 100-year area (HQ100) show where a flood of that size reaches, and the 300-year area (HQ300) shows the reach of an extreme flood. The neighbourhoods Lagecheck compares are statistical areas of Statistik Austria, each named after a street or a place inside it, and we rank the ones with at least 60 addresses. The map of Linz shows every neighbourhood. The report of each address names its flood area.

How we counted
The flood maps come from the federal ministry BMLUK, which publishes them under the EU Floods Directive, here in the edition of 2026. They cover the larger rivers. Small streams and surface runoff after heavy rain are missing from these maps, so an address outside the mapped areas can still flood. The address register of the BEV gives every address, and each address counts once, however many flats it has. An address counts toward a flood area when its location lies inside the mapped area.
The report of each address names its flood area, and the map of Linz shows each neighbourhood. The method explains how a flood area lowers LAGE, and on your priorities you set how much each part counts. Living in Linz gives the other measures for the whole city.
