Question
An equal-tangent sag vertical curve connects a -2.30% initial grade and a +2.30% final grade. The design speed is 50 mi/h and the elevation of the PVT is 802.3 ft. A storm drain is to be installed at the low point of the curve. What is the elevation of the low point? You answer must be in ft and rounded to the second digit, if you need to use values from tables, use "design" values (usually last column), not "calculated".
