4.7 Vertical Profile Grades

The vertical profile grade is the percent of elevation change along the centerline of the roadway. Vertical grades are necessary to assure drainage of storm water within the plaza to inlets and or outfall locations. Profile grades affectively reduce construction costs by more closely following the natural grade within the established right of way, balancing the quantity of excavation and embankment material and reducing the foundation and earthwork cost of bridges.
