The planting pattern of Seoul street tree could be divided into six patterns, that was, one row, double row, median strip type and bicycle road type. The protection facilities of installed street tree was inadequate, because it was so small and weak. Recently, the growth rate of street tree in Seoul was decreasing because of air pollution. Strong alkali soil proved to be inappropriate for the growth of street tree. Soil hardness of treepit equipped with treegrill was lower than unequipped one. From the analysis of correlation between the growth environments of street tree, we could conclude that the vitality of street tree are proportioned to the distance from the center of Seoul. The way of improvement for physiological growth and increase of street tree were as follows; establishment reform of street facilities, the installation of protection equipment, continuous and systematic management.

The risk of flooding and groundwater depletion is increasing due to the increase of impervious area in an urban area that reduces the volume of infiltration and increases the outflow of rainwater. The objective of this study is to examine the impact of installation of roadside tree protectors with infiltration pipes in terms of the change of the infiltration rate. Through this study, it has been attested that roadside tree protectors with infiltration pipes increased the infiltration rate and decreased water level on the ground, and could be applied in an urban area as the low impact development (LID) facilities.
