For the planning of urban greening it's useful to clarify the relationship between the green coverage areas and the total site area at large scale facilities in the city, and also between the length of roadside green and the length of roadside of various facilities. On the study of urban greening we inquired into site area, green coverage area, length of roadside green with many other factors related to the greening of facilities, at 546 sites in Kumamoto city. With this data, the ratio of green coverage and the ratio of green length at roadside, compared with each type and size of the large scale facilities, are analyzed and interpreted.
