To obtain the important information and parameter for the measurement of $^{137}$Cs activity per unit area on paved ground, this study evaluated their vertical and horizontal distributions. This study showed that $^{137}$Cs was retained in extremely surface layer with mass depth less than 0.5 cm$^{-2}$. This study also demonstrated the horizontal variations of $^{137}$Cs activity and the relation of the variation with grid size.
