The Podsljeme area of the City of Zagreb includes the southeastern slopes of Medvednica Mt., an area of 180 km2.

The pilot area includes parts of the city districts Črnomerec, Gornji Grad-Medveščak and Podsljeme.

Landslides mainly occur at the boundary between superficial deposits and bedrock, and many known landslides occurred at the geological boundary between Pleistocene and Upper Pontic deposits. Landslides are predominantly small to medium-sized, with sliding surfaces at depths of several meters to a maximum of 20 m.

Part of the Podsljeme area of the City of Zagreb was selected as a pilot area of hilly relief and a high degree of urbanization in NW Croatia, built of Neogene and Quaternary deposits extremely susceptible to landslides. The size of the pilot area is 20 km2, which corresponds to the production of landslide inventory maps, landslide susceptibility maps and recommendations for application in the spatial planning sector at the local level.
