According to the National Electrical Code Handbook, clearance over public streets, alleys, roads, parking areas subject to truck traffic and driveways on other than residential property is 18 feet.
The point of attachment of supply service conductors shall not exceed 9 m above grade. The drop has be located so that the clearance of the conductors at any point above finished grade is not less than the following heights; across highways, streets, lanes, and alleys - 5.5 m, across driveways to residential garages - 4 m, across driveways to commercial and industrial premises - 5 m and across ground normally accessible to pedestrians only - 3.5 m.

There is no required height but normally it is best to keep them 12 inches off the groung.
You can use the Pythagorean theorem to solve for the actual height of the incline because you know they hypotenuse length of the triangle as well as the angle. sin(theta)*950 = _____( actual height of the ramp ) With this new height value you can determine the minimum work needed to push the car up the ramp. Remember: W=m*g*h =(850)(9.8)(actual height) Hope this helps :)
There is no minimum height for junction boxes per NEC. Any use of a junction box that would be subjected to harsh conditions because of its height would have to be rated for the condition. Personally, in outdoor areas, I like to keep boxes at least 18" above grade in areas that get snow.
