For the intersection curve (R = 10 m) at Elm Street, station A (0 + 15) to station D:
(a) Compute the length of arc.
(b) Determine the curb-line gradient (percentage) from A to D.
(c) Determine the proposed curb elevations at stations B, C, and D. B and C divide the arc into three equal sections; that is, AB = BC = CD.
(d) Using the grade stake elevations shown in the chart below, determine the cuts/fills for stations B, C, and D.
