For each address in Dornbirn, 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. This story ranks the neighbourhoods by the 30- and 100-year areas. The neighbourhoods Lagecheck compares are statistical areas of Statistik Austria, each named after a street or a place inside it, and all 28 of them have at least 60 addresses. Dornbirn's own districts are a different division, which the data leaves out.

How do I find the flood area of one address?
Enter the address on the home page, and the report names its flood area. The map of Dornbirn shows the flood share of every neighbourhood. The method explains how a flood area lowers LAGE, and on the page your priorities, you set how much each part counts. Living in Dornbirn gives the other measures for the whole city.
How we counted
The flood maps come from the federal ministry BMLUK, which publishes them under the EU Floods Directive, in the 2026 edition. 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.
