How do you read grading elevations?
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 you use grading stakes?
Pound grade stakes into the ground on each end of the area you need sloped. The stake at the top of the slope is called the hinge. The stake at the bottom of the slope is called the toe. Determine the desired grade—typically 1-2% (1/8″ per foot to 1/4″ per foot) is enough to provide enough runoff.
