foundation’s size and the distances to the respective property lines. Setback dimensions are shown in
feet and hundredths of a foot, as opposed to feet and inches on architectural drawings. Thus, an archi-

A site plan includes not only the project but also the surrounding area. Site plans should outline loca-
tion of utility services, setback requirements, and easements. Topographical data is also sometimes indi-
cated, specifying the slope of the terrain. The grades at fixed points are shown throughout the area to
show the land slope before construction is started and the finished grade after construction is completed.
