A sag vertical curve will connect two tangents, a -3% grade and a +5% grade, 800 ft apart. The ravine in which the sag curve will be situated needs to be built up. The elevation of the curve at its deepest point must be at elevation 168.00 ft or higher to clear a major pipe installation. If the PVC is at station 00 + 00.00 with an elevation of 176.20 ft, determine the location of the deepest point of the curve and the height of fill required about the culvert.
