A vertical tangent at 4.7% intersects a tangent at -3.9% at a PVI station of 310+11.23 with an elevation of 903.00 ft. Using a vertical curve of length 493 ft., find the elevation of each full station along the curve. What is the station of the turning point on the curve? {If your calculations result in more than 6 stakes on the curve, evaluate only the first 6}.
