Sketch, at a scale of 1 inch = 10 feet, the general shape of contours crossing a 30 foot wide street having a 5.5% longitudinal grade, a symmetrically-crowned 2.0% cross slope, and a curb height of 6 inches. Assume that the road is crowned symmetrically and that each lane is 15' in width. No gutter pan is present. What is the distance between adjacent one foot contours? Your sketch should be a plan view (ie looking "down" onto the road, not a cross-sectional view).
