Finishing the Driveway
A key element of any site plan is information that shows how the building is posi-
tioned on the site relative to the property lines. Surveyors stake out property lines.
After staking out the property lines, the surveyor will then begin staking building
offsets. They are generally placed at critical building corners and used by the con-
tractor to begin constructing the building. In this site, you need only one corner
because you're assuming the front door of the cabin is facing due east. A close look
at Figure 13.1, shown earlier in this chapter, shows that the end of the driveway
lines up with the top-rear corner of the cabin. Extending from the driveway are
sidewalks that run to the front and rear steps. This locates the cabin on the site
(see Figure 13.8).

Civil engineers and surveyors typically use labels instead of dimensions to
represent the length of lines and arcs. Because there are no extension lines
indicating what's being dimensioned, the placement of the label is key.
Unless designated otherwise, a label represents the length of a line or curve
until it ends or intersects with another object.
For instance, the 83 driveway label indicates the driveway is 83 feet long from
where it intersects with the property line to the point it ends near your cabin.
Because there are no other intersections to consider, it would not matter if the
label were placed above or below the line. Label placement does, however,
become important as we take a look at the lower edge of the driveway.
