Sloping sidewalk made with modular, concrete pavers that allow some absorption of water to enter the
ground underneath.
Figure 14.10-B
The same sidewalk located further uphill with a poured in place concrete surface.
Both sections of the same walkway were graded to conform to the existing sloping landform.
Figure 14.11-a and 14.11-B
Two design options for linking an upper area to a lower area using steps (A ) and terracing or
steps (B)
Figures 14.11-A and 14.11-B show two examples in which the grad-
ing strategies of steps and terraces are used to provide transitions from
an upper to a lower area, in addition to the use of contour grading to make
transitions from one elevation to another. While steps and terraces
may allow movement from an upper area to a lower area, each step
and terrace is graded or sloped to allow water to drain off, to prevent it
