A digital automatic level is used to profile a road centerline. The backsight reading is 3.57 ft on BM #1, which has an elevation of 210.50 ft. A foresight reading on Turning Point #1 (TP#1) is 4.52 ft. At the next setup, a backsight of 2.91 ft is read for TP#1 and an intermediate foresight for Sta. 0+00 is read as 5.67 ft. Determine the elevation of Sta. 0+00 in ft.
