how to calculate slope between two spot
elevations:
In Figure 9.16 there are two spot elevations: point A and point B. The
horizontal distance H between the two points measures 120 feet. The
vertical distant V is calculated by subtracting the elevation of point A
from point B, and equals 1.2 feet. What is the slope between points A
and B?
S = V / H
S = 1.2 / 120'
S = .01 or 1 percent
The example of a tennis court shown in Figure 9.16 is gener-
ally not the preferred approach for grading a tennis court. Typically
tennis courts are graded so that the net is set at a higher elevation
(essentially creating a crown) with the playing surface sloped down-
ward at 1% from the net to the back of each side of the court.
