Likewise, people ask, what is a good grade for a driveway?
As a general rule, a driveway should be less than a 15% grade, which means that it should not rise more than 15 feet over a distance of 100 feet. If your driveway is completely flat, however, be sure to build up the middle so water runs off the sides and doesn't pool.
Furthermore, how steep is a 40% grade? Slopes vs. gradients vs. % grades
Keeping this in view, how do you fix a steep driveway?
- Step 1 - Determine the Incline of Your Existing Driveway.
- Step 2 - Remove the Old Concrete.
- Step 3 - Determine the New Incline You Want for Your Driveway.
- Step 4 - Dig Out the New Driveway.
- Step 5 - Level the Subsurface with Proper Drainage Sloping.

Is a 10% grade steep?
Keep in mind that grade is generally an average over the entire run. There are probably portions which are steeper and some more shallow. 10 degrees would be a grade of 17.6% (tan 10 deg = 0.176) and yes that is very steep, probably steeper than any road you've run on.
