contours, boundaries, roads, utilities, trees, structures, references,  and  other  significant  physical  features  on or near the construction site. A plan and profile sheet (fig. 15-6) and a typical cross section (fig. 15-7) are other information found on a site plan. Symbols Symbols  used  in  drawings  are  as  follows: . A contour  line  shows  us  an  imaginary  line, representing a constant elevation on the earth’s surface. Blueprints, or plans, use contour lines to show the final proposed  elevations. . Existing contour  lines identify the existing ele- vations  (fig.  15-8).  Existing  and  proposed  elevations  are used to figure cut-and-fill operations. . Proposed contour lines are those we work to- ward,  You  use  them  to  visualize  the  finished  product (fig. 15-8). . Utility symbols identify utility lines. The sym- bols for pipe are shown in figure 15-9. Once all the Figure 15-9.—Utility symbols for piping. Figure  15-8.—Existing  and  proposed  contour  lines. 15-7
