The present study attempts to obtain fundamental materials for green planning of residential quarter. The quality and quantity of greens in some typical residential areas in Sapporo city were surveyed. The scale of each surveyed area was about a neighborhood unit or a quater subdivision of it. The results obtaided were as follows ; 1) Within the land under survey, there were many unbuilt areas that were larger than or equal to 0.1 ha and they were used as public facilities, cultivated fields or vacant areas. The large greens within the above mentioned areas amounted to a large percentage of total green. A number of tree-covered areas were seen also in small unbuilt-areas less than 0.1 ha, the majority of which were home gardens. 2) The size of housing lot was relative to the number of trees planted. From the result of the present survey, it seemed possible to indicate that about 132 m^2 or more garden space was necessary for a sufficient ornamental effect by tree plantings. 3) It will need approximately 10 years after planting for attaining sufficient green effects in housing lots. 4) It seemed possible to predict the visual green in housing area through the following equation. Y=1.12X_1+0.49X_2+9.85 Y : visual green ratio (%) X_1 : tree covered area ratio (%) X_2 : grass covered area ratio (%).
