The Vuosaari dumping ground was created officially after Vuosaari had been annexed to the city in 1966 and after the Vartiokylä dumping ground had become too full to be used any longer. At the time, Vuosaari was a remote place next to the city boundaries against Helsinki Rural Commune and Sipoo. In spite of the remote location, the nearest dwellings were located only from the dumping ground. In addition, the place was unguarded and was full of rats and seagulls. The waste formed loose masses of matter and fires were frequent; the dense smoke from these fires was a severe inconvenience for the local residents.
