understand these conventions and expect them to be followed. Grading
plans contain a minimum of three layers of information: belowground
surface, or subgrade; ground surface, or at grade; and aboveground, such
as walls and other structures. The designer of site-grading plans needs to
provide information for each layer, using spot elevations and contour lines
for at grade, and spot elevations for below- and above-grade elements.
Details, elevations, and sections are used to provide additional informa-
tion to clarify the design intent for a site-grading plan.
The reader has a plethora of sources for researching the drawing
conventions used in preparing landscape-grading plans, sections, and
related graphic communication elements. It is not the intent here to dis-
cuss these conventions, although examples of grading conventions can
be viewed in the professional examples in a later chapter.

Figure 4.2 is one page from a musical score. Like a grading plan, it pro-
vides a set of instructions to guide the activities of the reader: in the
case of a score, the reader would be a musician, and in the case of a
site-grading plan, the reader would be a construction contractor.
A good example of this idea of the universality of drawing and com-
munication conventions can be found in music, starting out with the
composer: the creator of musical compositions. (See musical score, Fig-
ure 4.2.) Composers,

regardless of the genre of music involved (e.g.,
opera, jazz, rock and roll, or hip-hop), use a standard music notation sys-
tem. The music composed by the composer or artist is called the score.
The composer first creates music in his or her head by some creative
process. What is heard in the mind of the creator is transformed into
marks on paper, using standard symbols and notation. When read by a
musician, singer, or conductor, the score can be “heard” before the first
note is played or sung. The drawings we produce to convey a landscape
