In order to support a long-term planning of snow-removal system in a city of heavy snowfall, annual amounts of snow damage are estimated in representative years of different amount of snowfall in areas of different land use. The calculated amount of snow damage in Nagaoka City is greatest in the commercial area, and least in the first kind residential area, depending greatly on the land value and the establishment of snow facilities. And an additional calculation has shown that construction of snow removing ditch is not economical except in the commercial area if the snow carrying man-power is taken into account. The total amounts of snow damage in 20 km^2 urban area are 15.1 billion yen, 10.4 billion yen and 7.5 billion yen per year in the years of abundance (1986), average (1983) and scarcity (1989) respectively.
