If we use a length of 70'ft. From a starting elevation of 100' ft above sea level. How many feet will it rise in a 70' ft. distance to aquire a 10% slope up hill?

7 ft (one foot for every ten feet of length). 100 feet above sea level does not actually come into the equation.

it will rise 7 feet. making it an elevation of 107.00.
i do construction layout for a living and that seems like a very unpractical slope for a driveway unless you live in the mountains maybe. but you might mean .10 percent which in that case it would rise only .70 feet which is approximately
8 and 3/8 inches in my part of the country that would seem more appropriate.

10% = 0.1 = 1/10
so it must rise 1/10 of the length
70/10 = 7
