movement of earth. Another design approach to this site-grading solu-
tion would be to round or bow out the new contours located between the
two walkways in an arrangement that mimics the existing landform.
This grading design would tend to blend the walkways with the adjacent
landscape forms.
The next step the designer would take would be to estimate quantities
of cut and fill. The quantity estimate is needed when putting together
an estimate of probable cost for all aspects of the project, including con-
crete, landscape planting, irrigation, and any other designed elements
that make up the project. As long as the estimate of probable cost falls
closely within the project budget, there may not be a reason for con-
sidering design changes to reduce costs. In the case of site grading,
cost reduction may not be feasible, given the minimal amount of grad-
ing needed for this particular site-grading plan. The same assessment
could apply to the site-grading plan in Figure 11.29. The grading design
for this example required minimal grading, since the new contours do
not extend very far into the surrounding landscape, but instead remain
pretty close to the outline of the parking lot. A method for estimating
cut and fill quantities is covered in a later chapter.
