Math question for any engineers out here
I’m in the process of building a parking pad in this spot. I ran a string line to measure my retaining wall height. If I have the line 3 feet above the ground and check the line for level, it is still...

Harbor Freight will sell you a laser level for less than $30.00. Set the level at the front of the rig and using a two by four set perpendicular to the ground behind the rear tires measure how high the rear of the pad needs to be, skip the math.
Easier still. Take length of garden hose and fill it with water, holding one end of the hose a couple feet up against a board (the base end) at a known height (2 feet, 3 feet, etc) walk around with a tape measure and the other end of the hose (the roving end). Lower the roving end until the water is up to the open end of the hose. Measure from the end of the hose down to the ground. That length minus the height of the base end is the difference in elevation.
Water will always find its own level.
BTW, terracing the wall, go up 3’ feet, go in 3’, go up another 3’, etc, etc, and leaning the wall back into the slope will allow you to go up a lot more than a single height wall will.
