Linz is located in the Danube valley 200 km east of Vienna and approx. 100 km west of Salzburg. The Danube is a landmark within the city and supports ventilation of cooler air form the outskirts. The close neighbourhood of the Danube indicates quite some flood risk: in 2002 and 2013 large severe flood events took place, where the Danube banks and the lower historic centre south of the Danube were flooded. The historic centre of Linz is characterised by small, medieval, baroque to renaissance houses including several sacred buildings. Linz shows large plazzas with little to no green and a lot of sealed surface which has effect on heating up the centre as well as lacking leakage possibilities to soil and groundwater, concentrating discharge to the paved surface.

The political bodies of the Municipality are the Mayor, and the City Council. The administration is organized in 12 divisions, one of them responsible for Planning, Technique and Environment, which serves as partner in the project.
