A descending grade of 4.2% intersects an ascending grade of 3% at sta. 12+325 at elevation 14.2 m. These two grades are to be connected by a 260 m vertical parabolic curve. A reinforced concrete culvert pipe is to be constructed with its top 30 cm below the subgrade (or the lowest point of the curve)

What will be the invert elevation of the culvert?
