Vuosaarenhuippu

Vuosaarenhuippu is a recreational area in the northern part of Vuosaari in eastern Helsinki. Earlier it was the Vuosaari dumping ground and a place where land masses from construction sites was deposited. Through ecological restoration the area has been turned into a natural-like environment, the scale of which is unprecedented in the history of Helsinki. A large number of both flora and fauna inhabit the area. There are paths connecting the area to the nearby Mustavuori protected area.
Dumping ground.
History of the dumping ground.
Vuosaari dumping ground was a municipal dumping ground in the years 1966–1975 and 1979–1988. During the latter period it was one of the “big three”. The two others were the Iso-Huopalahti dumping ground and the Pasila dumping ground. The Vuosaari dumping ground is the second biggest dumping ground in the Nordic countries ever, second only to the current Ämmässuo dumping ground in Espoo, Finland. The waste taken there included domestic waste, industrial waste, and in all likelihood also hazardous waste.
The Lohja Kalkkitehdas dumping ground.
In the early 1960s, the Lohjan Kalkkitehdas Oy (‘Lohja Burnt Chalk Factory’) had a limestone quarry in the area and also a dumping ground. The quarry could later be seen in the scene as an old pond. The speciality of the place was pink marble, which first jota Lohjan Kalkki Oy and later Rudus Oy would retrieve in slates from depths up to 60 metres deep. It seems that also a stone crushing plant operated in the area, since the local residents made a complaint about the dust it emitted. As a result of this complaint, it was found that the amount of dust in the air was harmful for human beings, and the company was ordered to manage its dust emissions. It is difficult of find more precise information on this phase of the dumping ground.
A city of Helsinki dumping ground.
The Vuosaari dumping ground was taken to use after Vuosaari had been annexed to the city in 1966 and after the Vartiokylä dumping ground had at the same time 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 400 metres from the dumping ground. In addition, the place was unguarded and it was full of rats and seagulls. The waste formed loose masses of matter, and for this reason fires were frequent, and the dense smoke from these fires was a severe inconvenience for the local residents.
From 1975 the dumping ground was temporarily out of use, but since the use of the Iso-Huopalahti dumping ground ended, the city began to transport to Vuosaari again. The residents considered this to be an illegal maneuver, and they were strongly opposed to it. It was said the site was still badly managed, after all, it was still unguarded, and it was claimed in the media that hazardous waste, such as poisons, petroleum derivatives and solvents were taken there. In 1980, the housing cooperatives of the neighbourhood complained about the dumping ground to the health authorities, to the Helsinki Police Department and finally, to the Chancellor of Justice. Also, the Finnish Nature Conservation Society demanded that the dumping ground be closed. The Uusimaa Provincial Court banned the use of the site, and as the possibilities for the city to dispose of its waste were thus narrowed down, the importance of the Kyläsaari Waste Incineration Plant grew accordingly in the city waste management. Apparently, since the use of the site became banned, it consequently became a guarded site in 1981.
It seems that domestic and industrial waste was no longer taken to Vuosaari, but landfill materials were taken there, apparently up to 1988. However, some sources mention the Vuosaari dumping ground as the main dumping ground for the city of Helsinki in the 1980s.
The site of the former dumping ground thus consists of two parts, the former dumping ground proper, which amounts to 25 hectares, and the landfill hill, which apparently amounts to 35 hectares.
Since 1983, the Helsinki Metropolitan Area Council has been responsible for the area. During its last years of operation, the dumping ground was repeatedly taken up by the mass media. The closing of this site in all likelihood was due to negative public opinion.
The amount and nature of the waste.
A total of 3.4 million tons of municipal solid waste and 150 000 tons of industrial waste was taken to the site. (Some sources indicate only 1,7 million tons of waste.) In addition to this, construction waste, sulphur removal agents, solvents, hospital waste and ashes from coal power plants and precipitates and silt have been taken there. Among these, there are polycyclic aromatic hydrocarbons, volatile organic compounds, heavy metals and sulphur compounds. In all likelihood, these include also toxic wastes.
Restoration.
In the 1990s, a gas emission collection system was built in the area. It comprises 27 wells, plumbing, a pumping station, a flame incinerator, and a system of pipelines that takes the heat into a heating plant. After fill was no longer taken to the place, substantial amounts of clean excess land has been placed on top of it. At some point, either before or after the use of the site as a dumping ground, the area has been cordoned off with land walls. In spite of this, the former dumping ground has been classified as a risky site, and what comes to the rain waters and waters from melting snow that are being filtered through the land is constantly being monitored.
Landscape restoration and landscape.
The actual landscape restoration can take place only when the gas emissions from the landfill have ended. The new pipeline system is designed to accelerate the escaping process of the gases.
Excess land has been accumulated on the landfill hill for decades. The top soil of the hill has been brought to the site from the construction site of the Vuosaari Harbour. Earthmovers have brought 80 000 cubic metres of earth from Käärmeniemi (the site of the harbour). The land masses have been re-placed in an innovative way, preserving the order of the original land layers. Thus the top layer, with its organic matter, with all its microbes, seeds and organisms on the top, so that after they have recovered from the shock of the transfer, they can start a new life at the new location. Certain precious soil types with their plants were even transported on stretchers, as if they had been human patients. Thus plants, organisms and mycelia will continue growing in the new location. The maximum height of the place is considerable after all the excess landmasses that have been taken there, and thus the place can be seen from afar, and also, from the top of the hill, one can see most of the surrounding areas.
But after all this had been going on for quite some time already, the plans changed again. One commentator said that
The landscape restoration of the City of Helsinki Public Works Department, and especially the head of its workshop, Mr. Jukka Toivonen, has been lauded by The Finnish Association for Nature Conservation, and they have received the Countdown Prize from the Finnish IUCN Committee. According to the commentator quote above,
Inspiration for the landscape design has been drawn from the biotopes of the outer islands of Finland's archipelagos, the open slopes of heights, increasingly rare type of groves and the grazed traditional landscape, such as the dale of Häntälä in Somero.
In the summer of 2014 land masses from the future residential neighbourhood of Kruunuvuorenranta have been brought here. The landscape designers are eagerly waiting to see what kind of plants will emerge from the seeds in that soil.
The present state of the site.
Although the city of Helsinki began the landscape restoration only in 2003, over 400 plant species are found here, as well as many rare or endangered animal species. A significant part of the flora of the landfill area has originally come here with the top soils chosen from construction sites, either as already in plant form or as seeds. The Vuosaarenhuippu area is a kind of a reservation, into which it is possible to transfer rare and regional plant species which are overrun by the expanding development of the city.
As a result of the accumulation of land masses, the hill is a rather high one, and it can be seen from afar, and from the top, one can also see most of the surrounding areas. At the highest spot, at an elevation of 65 metres, there is a scenic spot, from which one can see a view to e.g. the Vuosaari Harbour.
From the north, there is an accessible route to the highest point of the hill. The accessible route begins at the parking lot next to Niinisaarentie street, and it proceeds along the official route. The route proceeds between the old dumping ground and the reed growth of the Porvarinlahti Bay and on to the northwestern slope of the hill. From there the route climbs up the slope to the northern point of the hilltop.
From the south, however, there is no route accessible for all. The most obvious route, and the shortest, as the crow flies, from Niinisaarentie to the eastern slope is not open to the public.
