Assessment method for highway project impacts on real estates
Vitikainen, Arvo
In Finland the planning of new highways, motorways, main roads and other public roads is divided into preliminary and final engineering stages. According to the new Highways Act effective in the beginning of 2006 the preliminary engineering plan shall contain a report on the necessity of the highway and the alternatives studied, the transportational and technical fundamentals, the approximate location of the road, and its estimated impacts e.g. on traffic safety, land use, real estate structure and the environment, and on human health, living conditions and habitability. The plan shall also present options for eliminating or reducing detrimental impacts and a preliminary cost estimate. Further, it is also enacted in the Highways Act that the final engineering plan prepared on the grounds of the preliminary plan shall present the measures, which are necessary for eliminating or reducing the detrimental impacts caused by the road. A method has been developed in co-operation between the Finnish Road Administration, National Land Survey of Finland, and the Department of Surveying at the Helsinki University of Technology, for the assessment of highway project impacts on real estates. By the method it is possible to reveal and describe the detrimental impacts of a road project on the real estate structure and the use of real estates. The method is bipartite. In the preliminary engineering stage the impacts of the new highway on the real estate structure are studied by a map survey availing e.g. the road plan maps of the Finnish Road Administration, the land data bank and the National Land Information System of the National Land Survey of Finland. This information is specified in the final engineering stage by interviewing the landowners and the authorities.
