How to read road construction plans

How do you read grade elevations on plans?

For example, given a benchmark at 100.00 and a grade elevation at 101.43, the difference is -1.43, which indicates that the elevation is 1 foot and some odd inches above the benchmark. Multiply the decimal part of the difference times 12 to find the number of inches. For example, 0.43 x 12 = 5.16.

How do I calculate my grade based on distance?

To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
