In a certain road construction is undertaken DPWH, It was decided to connect a forward tangent of 3% and a back tangent of -5% by a 300 m symmetrical parabolic curve. It was discovered that the grade intersection at sta 10+100 whose elevation is 150 m falls on rocky section. With the exposed boulder at elevation 102.67 to avoid rock excavation , the engineer decided to adjust the vertical parabolic curve in such away that the curve will just clear the rock without altering the position of pc and the grade of tangents. Determine the elevation and sta of the new PT.
